Title: Had my 24v BOB Turbo mapped finally
Post by: Damocos on August 02, 2011, 00:03:27 AM
After 15months of being off the road and 11 months laying idle since doing my turbo conversion i can finally say that i have a pukka running 24v Turbo Sierra :D  :D On Tues and Weds last week i took my car to Emerald in Wotton Norfolk to see Dave Walker and he spent a good few hours with his laptop on his rollers to fine tune my home grown creation and eventually after a few hiccups i came away with a  very respectable figure...... :DD  :DD

Im now at a power figure of 330bhp@4877rpm and 376.5ftlbs torque@4377rpm  :th:  All this is being done at 10psi of boost.

Wasn't all plain sailing tho, we had a problem with the external wastegate........ on the 1st proper run the gate wasnt opening at all :shock:  so was holding boost 100%, had a look and realised i had the vacumn hoses plumbed in the wrong way on the wastegate body  :oops:  so a quick swap and another run revealed that the 10psi spring in the gate was staying closed till 16psi......bugger!!!!! Also blew a boost hose off too...... I obviously didnt tighten it properly as im using mikalor clamps. If we'd left it at that it would have only lasted a few miles before going bang..lol  As we didnt have a spare spring we took the wastegate off and cut the spring down to try and get it to a sensible boost level that we finally got after 2 attempts. Its only temporary and i now have 2 new different poundage springs to try and maybe a boost controller if needed.

Anyways, all i got to do now is give it a good clean and slap an mot on it..... I have driven it but only down a tiny road and couldnt get any speed so i dont know what its gonna be like but im sure it will give me a grin. All going well i will bring it to Ford Fair [-o<

Here are a few pics.....

After fitting the air filter, its a tight squeeze.....

You at Ford Fair with the car?

If so I will have a good look round her as she looks ace in the photo's!

Nice result but there may be more to come.  Cliffs racer was making 300 from 7 psi but he was on 7:1 c/r so had a degree of safety built in.  Your torque low down must be good.  Are you on stock c/r?

Congratulations mate you should be proud that's a very nice figure ;D and the car is looking awesome to, a really nice stance and looks so clean  :mellow: a credit to you. Glad it all went well for you and you got there in the end with only a few small hicups. I will look out for you at ford fair, I may have a stand pass for the Middx RSOC they would love yours mate, let me know.

Hi i remember this from a while back , very good job you done there , that is really good figures form a std bob you must have bigger injectors ? , what clutch are you useing , i have a std boa single turbo had problem with boost but now sorted , but std cossy escort clutch wont hold the power on full boost .

Alright Gerry..... Im using some 440cc side feeds from an Impreza, they good for the spec i have. Im on a 4 paddle AP centre plate with the standard cos 4x4 clutch, holds the power no problem but its not user friendly...... i get a tiny bit of judder when slowing down through the box as well as the pulling away but im learning how to manage it ;)

Thanks Ade, was a shame you didnt get yours up to Dave when i was there..... Would have loved to seen it ;) I was talking to ya mate that took ya spot, he seemed a nice fella, even took me out in his Saff to show me how well his suspension setup works on the Norfolk bends.... :blink: I am hoping to get the Saff to Fordfair, i just got an issue with no indicators holding me up from getting an MOT :angry: If i make it i will be on the Sierra owners club stand so pop over and say hi :blink:

very nice and good to see a blown b.o.b,thats not bad for 10psi,can you post a pic of your dyno graph.
Dont get me wrong I am not knocking the set-up but is it just me or does anyone else think the turbo is a little close to the inner wing,you might want to sheild that.

Will the 24v definetly not take a bar of boost on standard compression? I notice you have a nice big a/r exhaust housing. I've been pondering the 24v swap for a while as i'm on 304/320lbs ft at 14psi from my very worked 3.0 12v cologne with a holset turbo and was hoping to achieve 400 just by throwing in a BOA on standard comp. Thereby having a simple cheap setup. But it looks like I would have to rebuild my 24v with my 12v venolia pistons and rods? Perhaps better to push 28psi with my built 12v?
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: cossiemk2 on August 03, 2011, 11:48:21 AM
1 Bar is the top limit with the standard pistons I think.

Although my pistons were fine, but it blew the rings.(probably getting too hot.)

With a RS500 style intercooler it should cope if mapped properly, but I wouldn't push it further.

That's no problem at all matey, glad to help, much better trying the "coilys" for yourself to see how they are, I'm soon swapping to 225 or 250lb" rears though as felt a tad soft at 200lb".
Glad you're happy with DW, well worth the trip for a good job, with no pub figures!!
Mine made around 315bhp, 320lbft on 21 psi, but max torque was at 4150rpm, which surprised the hell outta me for a 4 pot yb lump, would have wound up to around 32-34 psi but run out of pre load, so need to thread the rod down more, I upped the CR from the std yb though mines around 8.3:1, the lightened flywheel is worth it's weight in gold though!!

Did you find out why the torque drops like it does?
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: Dave on September 12, 2011, 09:59:10 AM
Sorry to say you can see by the graph that turbo does not suit the engine.

The turbine end flows too much so it spools late & the compressor end flows too little hence the nose diving torque plot!

It will be off the effiency maps.

Post by: v6gerry on September 12, 2011, 22:10:05 PM
HI thought i would put R/R print out when dave done mine , std boa engine single t3 turbo 320 delphi injectors, as you can see i was losing boost , it turned out to be just needed a bleed valve , now sorted running 8psi and holding 5psi right up the rev band , need to get it back on R/R to see what its producing now  ;D

Title: Re: Had my 24v BOB Turbo mapped finally
Post by: Dave on September 13, 2011, 00:34:30 AM
I would say looking at your graph v6gerry your turbine end is way too small.

What is happening is your getting alot of back pressure by 3.5K which is forcing your wastegate open causing your boost to drop & the back pressure is killing your power.

When you fit the bleed valve your reducing the pressure on the wastegate spring which means it can cope a bit better with the back pressure from the exhaust so you run a few more psi of boost!
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: robrs2 on September 13, 2011, 01:01:57 AM
Looks like the T3 is a sensible option for single turbo.
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: v6gerry on September 13, 2011, 07:58:48 AM
Hi Dave since fitting the bleed valve and having it re-mapped live the power is up so much the std cossy escort clutch slips badly , so when i've done the clutch i'll get it back on a R/R to see what we have . when i fitted the valve on the first run we hit 1.8 bar so adjusted it back , then field motorsport remapped it . it really picks up and go's untill the power comes in then clutch slip , i think its a good match for this set up . will post up when i've R/R it .
Cheers Gerry

Post by: Dave on September 14, 2011, 00:23:25 AM
If your happy that is all that matters :mellow:

Is this a T3 from a Cossie or something cause that should set off alarm bells as it's 2 litre.

The same turbine shaft spec was used on engines from 1.4L to 2.5L.

Never fitted to anything bigger than a 2.5L.
Of course the turbine housing matter's too but if a Cossie then it's the smaller of what's around.

The turbine side of the turbo is too small for a 2.9 engine as it will flow more exhaust than the turbo can flow at anything over a few psi!

When does it actually hit it's set boost as it's already there when the graph starts at 2.5K!

Title: Re: Had my 24v BOB Turbo mapped finally
Post by: v6gerry on September 14, 2011, 18:36:29 PM
Hi Dave yes its a 4x4 cossy turbo , i went for this because it was the same turbo as the 2.8i tt set up i had on my old engine , i won't know about when it reaches boost untill i get the clutch done and back on the R/R . i,m not that gend up on turbo sizes , you seem to know a lot about them is it your trade as a job ? like your input tho dave , what turbo would you use just out of interest.

Title: Re: Had my 24v BOB Turbo mapped finally
Post by: Dave on September 14, 2011, 23:06:44 PM
I have done alot of research & have alot of experience with turbo cars.

Firstly I would get a China GT30 copy & get it VSR balanced.

A good intercooler & pipe work will give you a turbo that's happy at 300 - 500 bhp for about £300.

China turbo's are still a risk but one I am willing to take.

They get better each year & are nothing like the horror stories of old.

A 24V is gonna be making at least 20% more power on the same boost as a 12V mate, TT used to max out their turbo's for the installs to make them responsive.
So a STD T3 is already maxed out on a 2.8.

TT built a few 24V turbo's they used T3's but they used two of them!
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: v6gerry on September 15, 2011, 18:53:42 PM
so do you mean the GT30 flows more ex gases and won't have the problem i have had with pushing the waste gate open ?
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: Heiki on September 16, 2011, 14:08:41 PM


I have made good results on the 24v vith one of these gt35 turbo`s.

http://www.cxracing.com/mm5/merchant.mvc?Screen=CTGY&Store_Code=CXR&Category_Code=TRBT35

They have a 61.3/82mm compressor wheel and a 62/67.8 turbine wheel. .70/.63AR

Yes a copy of a GT30, 35 or even a GT40 will do the job.

Without working it out at a guess a GT30 would be best as it will spool up pretty fast on a 24V.

Yeah I remember you saying.
The turbine is a little different to a true GT35 by the looks of it.

You got a dyno plot so v6gerry can see the difference.

Also note it has no inbuilt wastegate.
Most of the China copies do & they are usally journal bearing.

Would be a good idea to start a new topic now as it's not really got anything to do with Damocos's topic anymore.

That would be a good idear Dave as it already showen we have all done differant set ups with diferant results that can be built on , i  for one don't no much about turbo just no that it should give you more power , like you your really indepth with them with very good advise.

Thats a big hill  ;D

Did you find out why the torque drops like it does?

Yeah it was where we cut the wastegate spring in half.....!!!! It wouldnt open till 17psi.... :o So to get it mapped as we couldnt locate another spring we cut the original so the gate would open at 10psi but towards the end the gate was staying open permanently so the power just dropped off  :( I now have a boost controller so its now set perfect. After the mapping i took it for a brief spin up the road but you could hear the screamer blowing where the gate was open so it would boost then drop really quick. Its ok now, i have an 8psi spring in place and all seems well but it will be a few weeks till i know if it holds boost properly. Should be ok me thinks...... :unsure:

Really........ Bugger!!!!   I did alot of research before buying a turbo and from what i read and asked the one i have is about right?  Hmmm Would you think that where i had wastegate issues and the gate staying open all the time where i cut the spring would be one of the main reasons why the power dropped like it did? I did drive it on a 12psi spring without a boost controller and it was holding boost till 18psi but i didnt notice any drop in power through the rev range..... Admittedly i only did this twice as im sure it would have gone pop...lol and i only took it up to 5.7k  

The turbo i have is a KKK27  Anyone know what measurements this turbo has as im a bit underknowledged in this area. Atm the turbo is apart so i can measure the compressor and turbine wheels. What else do i need to measure to get the right info?
Title: Re: Had my 24v BOB Turbo mapped finally
Post by: Dave on February 24, 2012, 22:50:32 PM

I can only see what your graph tells me mate, so if you have had issues & it's affected your graph then it will also affect what I see so then what I say is then rubbish!  ;D

I am assuming everything is set up correctly.

Your torque is dive bombing above 4K it shouldn't be, if your pulling 375 lbs of torque then you should make a very similar horse power figure with the 24V. If not somethings wrong.

So your down by around 50 hp.


What is the full part number from the plate of the turbo & I will see what I can tell you.

Hey Ade  ;) Not much really.... Did Nurburgring in Aug, did nearly 800 miles in a day there and back. Was bloody hot tho and had a few little issues but got me there and back so all good ;D Used the car for a weekend jaunt to Amsterdam to see friends in November and its been tucked away ever since lol. Have fitted a 3.36.1 rear diff now and I am literally about to have the gearbox out to get it freshened up and try an organic clutch as I'm pissed off with the harshness of the 4 paddle :angry: Also booked into Emerald next month for a health check as my mate Pete has now finished twin turboing his BOB Capri so it made sense to travel up at the same time ;D

How's the 3dr coming along?

Hi Gerry, do you get any judder from pull away? That's what I get with the 4 paddle.... Apart from that its ok but just the initial pull away I hate. If it was an out and out track toy I would live with it but on a day to day basis its shit  ;)

I think hydrolic is the way to go much better control then cable , really pleased with the alcon nearly went AP route but got advised not to for road use , cos they are heavy / in or out for track use . i'll try and get hold of that chap I spoke to i'm sure he had organic and hated it .

if your flywheel is not ground flat then clutches will judder on take up,could be a high spot.I have a twin plate paddle clutch and get no judder,its either on or off but the hydraulic set up i have works well.
  Does your paddle clutch have the springs on the centre boss? if so it could be those worn out,or if its solid it will judder if the flywheel is not flat,they act like a mini dual mass flywheel and protect transmission.

i had my f/wheel skimmed when fitting my  alcon , my prop shaft is direct with no rubber in it , now its bedded in it seems fine , would like to go hydrolic but there not much room under bonnet for m/cyl .

I fitted my master cylinder in the car under the dash,fitted on the otherside of the pedal pivot and facing backwards,this increased my fulcrum and made for less effort on the foot but an utter twat to fill up to bleed the system :P its not leak as yet so hopefully wont have to bleed again anytime soon.

When I fitted the clutch the flywheel looked good as it had been skimmed previous and had only done approx 4k on a std clutch with std power. The plate itself was brand new and it does have the sprung middle. It is an AP one tho and have heard they are quite fierce. So maybe then it could be the flywheel contributing..... I shall be getting it skimmed again to be safe ;)

I am looking to do the hydraulic conversion too but as I run a big servo I cant get a master cyl out the bulkhead :( I would be interested to know more about your setup and if you run a std pedalbox ;D

its a standard pedal box but i modified the clutch arm and made a plate to hold the master cylinder.

How are you getting on Damo any updates ?

Hey Ade  ;) Not much really.... Did Nurburgring in Aug, did nearly 800 miles in a day there and back. Was bloody hot tho and had a few little issues but got me there and back so all good ;D Used the car for a weekend jaunt to Amsterdam to see friends in November and its been tucked away ever since lol. Have fitted a 3.36.1 rear diff now and I am literally about to have the gearbox out to get it freshened up and try an organic clutch as I'm pissed off with the harshness of the 4 paddle :angry: Also booked into Emerald next month for a health check as my mate Pete has now finished twin turboing his BOB Capri so it made sense to travel up at the same time ;D

How's the 3dr coming along?

That's good news then mate  ;D  eu touring  :mellow: I found the six paddle Alcon fine really, people I have spoken to say its best to have the flywheel ground as it gives a much better finish removing any high / hot spots. I had wondered how Pete was getting on, any pics of his Capri ?
That sounds like a good day on the cards at emerald then Damo two v6 turbos  :wacko: what date is it?

Mine well....  I have a new 6 degree beam and a supra diff I'm sorting out ATM and the new engine is well underway, not sure when it will be back on the road yet  :unsure: but defo this year.

Well I have gone for an AP 6 paddle with a std cover. Have had the flywheel skimmed again and for now just a new grp A quadrant and cable as I simply don't have the time to sort a hyd conversion :( Asked loads of people for info and advice and this seems a good route but we shall see...??? Im off to Emerald on 17th & 18th April so got a bit to do before then. Pete's Capri is all ready so will be interesting to see how that performs ;D

it shouldn't need alot as its just boost they have to deal with.the boost fueling and timing is already set on the map sensor parameters.but be good to get a graph.get them to set the igntion to 31 @0 throttle above 3k to 6k.leave the full overun on and you should get some nice pops and flames when you lift off

Watch the egt aswell as ades standard exhaust valves got a little to hot.you need nimonic with bronze guides to run over 850 degrees celcious on a long pull.be ok for the odd squirt on the road but watch it if on track.

You could use stainless steel valves and Berrylium Copper seats.

Here a picture of the valve seats and valves I use for my 7.0 v8 twin turbo.

Didn't make it  :( Pete needed a new BOB waterpump so gotta wait till one comes in from Burton's, about 2-3wks  :rolleyes: So re-scheduled for mid may ;)

hi have you tried your clutch yet , I heard that no one done the bob water pump which I thought strange but they do . someone bought my old one I had for that reason!! looking forward to getting mine on the road next week  :mellow:

Been re reading through turbo stuff for the 24v as I started to mock up my bob for a pair of Nissan r33 gtr turbos. There like T28's. well hit a few problems.
Position of the passenger side is easy, but the drivers side means moving loads of pipes and bottles. Not what I wanted. Also it tight on room anyway that side.
Then I found I had been sold 2 cracked turbos, waste gate seats on both are craved through. I'm guessing the person I hit them off knew as they were cheap And I didn't know that was a fault with them.

So I'm now looking to a single turbo, manifold is now mostly built. But what turbo spec for around the 350 bhp area with good boost from 2500 rpm???
