After a few days of street tuning and workin out some bugs with the datalogging, I made some base runs on the dyno tonight to see where it sits...

First run was 442 whp 288 tq corrected... Using a Dynojet. Ill post the graph later on
wastegate set to 1 bar, and creeping up to 20 psi slowly up to 8200
made a couple more runs fixing the A/F a tiny bit.. it was a tiny bit lean because my wideband had been reading slightly off compared to the dyno..
Started to rev higher and it was still makin power up to 9000... thats where we stopped...

This is still on PUMP gas, 91 octane, with nothin touched for ignition basically... very mild..
the shitty plugs i was using started crappin out on me, so we stopped, but this was a good start I would say... Not gonna go higher on pump... still gotta make some mid range power, it hasnt been touched at all.

about time !!

can i borrow your shortblock ?

ZeremiaH

wow, very nice we have almost the same build. Mine is not done yet but I hope to get the same results.

Topdawgg

not sure why the 44mm was creeping up to 20 psi... wasnt too impressed.. Im gonna change springs and get the 20 psi throughout the powerband, not just up top

gotta feel good to finally get it on the dyno. congrats topdawg, im sure youve been waiting a long time for this.

that engine is way to sexy for low boost, pump gas, and a single plate clutch! mmmmm pauter rods.

i feel your pain, 20psi is crazy on pump, 91 at that, i was creeping to 20-21psi on my old manifold, and with my new manifold i got it down to 17.5psi at 9k, i only spin to 8k on pump though. people were telling me i was crazy for wanting to go dual wastegate!

dyno chart, and pics of the car please

Once I knew that there was still power to be made up around 9000, i called it a night... and put the rev limit back down to 8000...
no point really...
but we also richened it up, so its even better now.... alittle less power, but its conservative..

4" DP into a 3" exhaust? Interesting.

Either way...looks great man.

just for daily driving... IDEALLY i wanna just remove the 3 inch for the track and for big numbers.... thats how i set it up

0morgan@synapse motorsport

are you gonna do any race gas tuning or hit the track as is first?

Topdawgg

race gas and a BIG tune first...

0morgan@synapse motorsport

haha i wish you were on aem, i would love to see the similarities in the tune.

Creeping from 15psi to 20psi and you wonder why its still making power It just means your turbo isn't blowing hot air yet.

Still 442 on 91oct, gsr cams and nothing too fancy, good numbers for the GT35R. I bet it still has a decent spool time too.
