What wheel/tire combo are you running Harry?

Since I can't drive.

13.2 at 117mph is all I can do.

Broke an axle trying to launch it with drag radials and 4000rpm. Didn't get a pass.




Upped the boost and took it to DynoJet ($50 per 3 runs vs $250 / hr at Dyno Dynamics). 367whp, boost spiked over 29psi and come back around 26psi



More importantly, I can get a nice flat torque curve with 7psi boost that creep to 13psi and make 248whp at 12.5psi. Good for 1st and 2nd gear pull on the street.

Great work and glad you stuck with it and were able to realize how possible it is to make good power from this platform :)
Thanks.

I think I'm done increasing HP, unless I can do it without increasing torque.

Torque breaks stuff, my stuff isn't breaking and I'd like to keep it that way.

Read it for yourself, I never used 86 or older stuff. Not sure if I ever had one open.

Can't tell you power numbers, between the dynos, different intercooler, different turbo, different fuel, different muffler were used. What I can tell you is what timing I used.

Timing on the 290whp on E85, on LM and HEP.


Timing on 350whp on E54, on Microsquirt and 36-1 wheel.

Simple 1 chip upgrade in the 87 LM vs 2 chips in the 86 LM.

You did see my 350whp dyno, right? Good head that can flow mean peak HP is in the later RPM.

I can't believe that even in these they didn't bring the MAP out into the engine compartment. What other differences are there in that upgrade?


I saw your post about the Ed Peters comparison today. The head I have was ported using an Ed Peters head as an example. I have heard bad things about that style of porting though. That it doesn't flow much better. My head has +1s as well.

I'm not sure if this question was directed to me but I'll answer.
Flow is key to make power. The classic 300ft lb and 200hp dyno on 2.2/2.5 turbo dodge is because the stock cylinder heads just don't flow. You need flow to make horse power. Make the cylinder head flow, peak power will come after 6000RPM instead of 4000 RPM.

My setup has a minimal boost of 13psi, as you can tell from the second graph where boost started at 9psi and creep to 13psi at 7400rpm.

Distributor and HEP robs power due to inaccurate and inconstant spark timing. You can see this happen when you use a timing gun to time the 2.2/2.5 engine.

If the LM works, leave the wiring and upgrade to 87 TII LM would be my suggestion.

I have one for my truck so I tried it against the crank pulley .. bolt spacing is definitely wrong - an entire center for it would have to be made - or something to space it out above the heads of the pulley bolts as they prevent it from sitting flat in the center of the pulley

- something like a thick aluminum washer with a hole for the center bolt and 4 or 5 bolt head reliefs drilled into the backside of it (?)

Something like that would be easy enough to machine. And nice to see the cutouts don't have to have square corners inside to work.

Re: 350whp at 6250 rpm

For the timing wheel you welded to the crank pulley. They have to be steel for the timing sensor to read them right? I love my aluminum UDP and really wouldn't want to lose it. Good Results. I'm not surprised you made 250hp at such a low boost # at all.
