Default My powerlab gt37r numbers

OK, so at last i manged to fix my utec voltage and some breathing issues.....power kept dropping at around 5500rpm.

After a 4hour dyno session my DW600 injector was maxed.
Keep in mind it made stock 202whp on the same dyno a while back....dyno was calibrated two days ago.

-437whp with 7.8psi, 95 pump, power all the way to 7000rpm.
Then manage about double spring pressure on my MBC
-542whp/464lb/ft with 15.5psi, 100 race fuel power to 7000rpm....ran a bit leaner due to IDC with very conservative timing.

will post up sheet tomorrow.

nice.

so you needed 100octane to run 15psi? Intense ran that turbo up to 700 hp, so it seems that mid 500s should be doable on pump.

he probably was running high octane to get that much power out of 600cc inj. I bet your IDC is way too high.

great #'s in for dyno sheet.

I'd guess but around here we don't like going past 1bar with pump.
Low stock numbers due to altitude, around 5000ft.

Ya IDC hitting 90's....static fuel pressure just under 3bar so I'll bump this a bit tomorrow when i pick up my car and maybe just one run for safety.....might be looking for 750cc.
My intention is only to run high boost map for a few 1/4 passes if my axles last

I wish I went with the 37r. I would get some 750 or 800 like you mentioned beter safe then sorry. And after you get use to it you will be wanting more. Enjoy the power.

Congrats Nice numbers for the PSI levels, especially at 5000 feet elevation... or are these numbers after a correction factor for altitude?

Not knocking your numbers, since 550whp is no slouch....but why not stick with the GT35R and get those same exact numbers with less lag? Unless you wish to push it upwards of 650whp ( I have no idea what your plans are ).

So you rather have a Powerlab GT35R Kit instead of your GTM TT HR Kit?

and the HTA wouldnt be insane either. maybe on a honda or any other sub 3000 lb car.

a 76mm or bigger is insane for a single. a sub 650 hp turbo is never insane.

Lag's my friend, i have much more traction out blocks and as soon as i hit higher gears you're always in the boost....prob was just loosing power after 5500rpm in past.
Lets see how it goes now.
I don't think the gt35r would if made the same power at set manifold pressure, especially at the top rpm range.

They recon altitude loss on turbo cars 3% around here, numbers corrected accordingly.

HP loss is about 2-3% for every 1000 feet of altitude. 5000 feet you are losing about 10-15% so great numbers with this disadvantage

You sure this is on Turbo as well? most guys around here correct 16-18% on N/A and Supercharged cars.
