Dyno sheets
« on: July 31, 2010, 10:09:08 AM »
Just wondering, as I'm contemplating both supercharged and/or turbocharged 12v v6 builds (even if I'm half way through a NA build)

How much power has people made on their builds? I have a hard time finding any posted rolling road results or dyno sheets.

It would be great if people would post more of them on here, or just their results, especially interested in torque figures from supercharged engines (found some from Cossiemk2's supercharged 24v with un-intercooled m90), but anything would be fun to see, even 24v v6 builds €Ã‚ 
PS: NA tuned figures would also be very helpful just to see if there's any point in NA tuning the old Cologne...

I agree on that.

I posted my dyno sheet for all to see.

People saying I have this HP and that torque is fine but prove it.

Im not claiming to have a 1/4 mile monster but I post results if I have them.

I should have another 50 HP or more now, but until it's been on the rollers I haven't got proof.

One day, I'll get near some rollers. But until then it will be ass dyno figures :D

I believe sparkplug has some dyno figures and are very typical from what you'd expect from a supercharged cologne. See picture below nicked from the xr4reg.

That looks great. It's nice to be able to see the difference between TT's and Superchargers like that.  It sure looks like the TT conversions are quite effective, but I love the torque figures for the superchargers, and I don't like all the plumping for turbo's

Maybe one day we will have a dyno section on here for you to look at.

A dyno plot can tell you alot.

The peak figures are not as important as the shape of the curve.

Basically a N/A 12v will feel strong upto about 5K then flat = easy to drive fast but unexciting!

12V superchaged will be the same but between 2 - 4K it will pull like a train & be responsive.

12v turbo if a TT one will pull hard from 2K to 4.5K but goes flat around 5K. Alot like a supercharger but with a sec of lag or so.

12v with bigger turbos will build power as you climb the rev range making it both exciting to drive & feel very quick.
However it won't be as easy to drive as the other 3 & no quicker than the other boosters but you will swear it was.

Depends what you want.

24v is pretty much the same but figures are higher & don't go so flat at 5K+
