What's up guys!!!

I finally had the time to dyno my car too bad the whether was almost 100F

01 C5 ZO6

Engine/transmission

Built 347ci 9:1 comp
Brutespeed cam 232/240 595/608 115
stock untouched 241 heads.
All valvetrains.
stock intake and tb.
RAM Carbon twin disc clutch / aluminum flywheel.
RPM T56 trans / stock rear 3.42

Turbo setup:
Custom build ST80 Turbo kit 1.15A/R
3.5' Downpipe going to STOCK TI EXHAUST for now.
Percision WG
Tial BOV.

Fuel:
RSI Fuel pump hanger (great product)
DW pumps.
Fast rails.
83lbs Injectors.
Aeromotive fuel pressuer.

Cooling:
Dewitt Radiator.
Hypertech thermostat.
stock water pump.
also waiting for the dewitt bigger fans..

and some suspention/brakes/show parts here and there

couple of pics




















on 10psi made 598rwhp 549rwtq SAE with very safe 10:7 A/F Ratio, 15timing.
91octane, 98F whether Running heavy 360Forged 19×12 in the back...


The car spools extremley fast on the street and drives awesome I'll post some dyno/street vids very soon (needs some better tires though) ..

Waiting for the boost controller to arriver then we'll turn it to 14-16psi.

Even though I wanted 600-630rwhp on 10psi I'm still very happy with the numbers with the safe tune , whether and stock catback...

Do you guys think it's possible to get 700-750rwhp on 14-16psi??
Hopefully we'll find out in the next two weeks..

Let me know what you guys think?

The math is pretty simple as far as break horse power. The crude number is that you'd get about 100% your N/A power for every 1 bar (~14.5PSI) of boost. You'd need about 830 BHP to make 700 RWHP. So your motor would in theory have to make 415 BHP without boost to make 830 BHP at 14.5 PSI.

So, yes, I'd say you should be able to hit your goal with about 15-16 PSI.

Thanks.
I Dynoed the car before the turbo with stock headers/heads/intake and tb.
very rich tune the car made 379rwhp 9:1 comp I think thats close to 440 BHP

I guese will find out in the next two weeks about the numbers



Still not nice enough for me I need to turn it up
But the damn stock 241 heads are killing it ..

nice work, looks great

That sounds about right. I think you'll hit your goal around 15 PSI.

I'm a little iffy about the 15% loss rule with a manual transmission when it comes to Corvettes. I think even though Corvettes have IRS, the loss is closer to 13%. Either way, your 440 BHP sounds about right and you'll probably see about 840-870 BHP at 1 bar.

You're not on 241 heads, are you? Your car should have come with 243s since it's a Z06.

Thanks man..





I agree I always thought the Vette IRS have 12-13% loss.
I sold my 243 heads long long time ago I had MTI 317 III Heads but I also sold them looking for aftermarket casting heads

Thanks.

Gotta watch out for those devilish smiles. Usually means plotting is underway

Gotcha. I must have misunderstood and thought you may have had 241s.

OK, yeah, get yourself a set of AFRs or something. They're money but they're good. (Especially ported)

Not a fan of the interior of the C5 but the exterior is to die for. Nice numbers and vette even if it is school bus yellow.

I talked to Tony@AFR and that's what I'm going with very soon..
Gotta save up though when I heard the price I was but I also was when Tony told me the estimated power gians..





thanks.

nice bro.... lets see some new numbers with your boost controller!!!!!!

SCM_Crash

iTrader: (2)

Yeah. It's hard to beat the numbers you get from AFR vs. the power gains from just porting stock heads.
