My Escort Mk2 is finally mapped.
« on: September 09, 2013, 14:04:58 PM »
It took almost  a year after fitting the turbo but finally had it done last week.

Running 0.8 bar/12 psi it made:

356 hp @ 6220 RPM.
411 Nm/302 ft/lb @ 5820 RPM.

Torque is a bit disappointing I think and could do with some improvement but at least it's very usable.

Spotted your car at fordfair but couldn't see you.

Is it a standard 24V with the turbo?

It's got lowered C/R pistons and running BOB cams.

Custom intake and exhaust manifolds.

Nothing done to the heads, they are bog standard BOA.

(E.g. the sprint sessions...)

Should go well now it's mapped :)
Keep it very sideways..

411 Nm/302 ft/lb @ 5820 RPM.


140.4!! drag hp? Did they do the pull with the brakes on?
I'm not much into dyno testing, but something looks a bit odd here.

Well it might have something to do with the fact it's 4x4??

I always go to this dyno so it must be right?

I'll take a pic tomorrow.

CR is a bit low, I think it's 7.5/1 so probably more suited to higher boost.

Horse Power is O.K but peak torque is way down mate.

It looks like you have a boost issue, pity you couldn't have data logged it  :rolleyes:

On the run the boost came in late so you missed the mid range torque peak but was there for the end so HP was alright.
The torque plot will follow the spool of the turbo & you can see yours is flat until 3500rpm

You said before it's on boost around 3000rpm normally so you may have a wastegate problem again or something.

Once that's sorted you will be around 360lbs & the extra momentum will add a bit more HP which will be more like it.

Better still run a bar & it will be around 400 hp / lbs which is a nice place to be.  ;D :mellow:

140.4 hp of drag is a little high but only 20 hp or so for a 4x4.

MAHA dyno's measure actual drag on coast down so a rubbing brake pad, tyres low on pressure etc etc will show up.

I found one reason for the high drag : the front left wheel bearing is fubared.

I fitted another dumpvalve as the old one started venting above 0.5 bar.
I don't trust this one either!! :angry:

I'll also try to disconnect the wastegate and see how it spools then.

It's a GT3582 going from Dave's advice.

And for Dave: I went on a drive to day and wrote up the boost.

RPM vs Boost

2000  0.2
2250  0.3
2500  0.4
2750  0.5
3000  0.7
3250  0.8
