My vote is ~400 RWHP.

Make sure you tell us where you end up.

usually 15-17% with FF and MR and RR cars
usually 18-20% with FA and MA cars

525bhp (brake horsepower) not 'crank horsepower'
451whp

480bhp = 413whp

not being a dick, just trying to help spread factual numbers and legit expectations.

I'm going to agree with some on here at ~410whp.
tuning is vital to reliability and performance.

Re: How much HP from an 02-04 Z06 with Bolt-on Mods

Attached is chassis dyno results of STOCK :

01 Z06 375 HP
03 Z06 405 HP
09 coupe LS3 435 HP

If you take all 3 runs ( 9 pulls total) of each you will find they ALL come out with a 11% drivetrain HP loss.

Pre C5 had the higher drivertrain loss, not C5 and newer with MN6/transaxle

Cannot take the drivetrain percent loss used with other makes/models as the Corvette drivetrain was designed with rear transaxle that has less loss.

Yes A4 trannie has a bit higher loss but nowhere near 16% loss.

Re: How much HP from an 02-04 Z06 with Bolt-on Mods

the corvette might have a lower draw (~11%) but there have been a lot of dyno's of corvettes showing 13-14%.

the cars are under-rated... my car dyno'd 15bhp above where a '01 should be.
dyno a car without a hand-built motor and you'll find a little more stable dyno result.

look at a car like the G35 and the whp vs bhp numbers are almost dead on 15% as with MOST FR cars. (~230whp-AT / ~250whp-MT)

AT usually takes more power from the engine and differences in fluids, tires, rolling weight, etc.
A/C will take 10% of the power and if the fans kick on you'll also lose power.

lets also not forget that a dyno is just a measurement tool for tuning and all are going to be different depending on the operator.
Poll: Dyno numbers of 405HP stock Z06s only
read that thread, the results are all over the map.

Re: How much HP from an 02-04 Z06 with Bolt-on Mods

My car had 358 with stock tune, and according to my tuner, who owns a corvette, the loss is about 65. That works out to 423 hp at the crank. I have seen half a dozen write ups about the c5z, and they all say the engine is underrated, and makes more like 425. That's about 16 percent. It probably isn't the same at all throttle levels, and probably increases with hp. Mine is at 407 rwhp, and I'm at 90 percent injector load at wot, with 28lbs injectors. Can this info be used to extrapolate the true hp? And the corresponding parasitic loss?

Re: How much HP from an 02-04 Z06 with Bolt-on Mods

The 3 dyno results shown in my last post was 3 different Corvettes, at 3 different chassis dyno locations in the country and done over a span of 7 years

Considering all 3 were stock, GM rated 375, 405 and 435 HP and all NINE pulls were within 11 percent drivetrain loss shows the loss % is valid and that GM ratings are correct.

The kicker was in including the LS3 dyno results as GM switched from the older J607 dyno test standard considers that the engine was run on a 60F day with 0% humidity and a barometric pressure of 29.92 in-Hg

to the newer SAE J1349 standard of 77F (25C) day with 0% humidity and a barometric pressure of 29.234 in-Hg (99 KPa) which is required for MMVS federal testing GM must do to get car legal for selling.

So NO the GM numbers are not underrated and the 3 dyno results show if it's a 2001 Z06 or 2012 LS9 the GM numbers are correct and the drivetrain loss is close to 11%.

Of course numbers change as if car is at sealevel and 50 HP less if car is at 4,000 feet elevation and not that GM is fudging their number low.

zsteve06 says his 02 Z06 reported 358 rwhp on chassis dyno to flywheel rated 405 HP

Oh, that is just about 11% drivetrain loss
so added another testpoint shows that number is correct and any difference is error of chassis dyno, weather/elevation correction, improper strapping down the car or

Flat cheating to bloat the numbers.

Re: How much HP from an 02-04 Z06 with Bolt-on Mods

February 13 issue of Vette magazine, article titled Arctic Assault, page 74-76, direct quote.
"To get things rolling, Redline Motorsports dyno tests the show-room-stock GS. The results--425 hp and 401 lb-ft at the rear wheels--reveal this Vette may have left the assembly line with more power than GM advertised. (Sub quote) Typically our dyno reports 390 to 408 rwhp on the 12 Grand Sports, so the 425hp peak is quite a surprise, (end sub quote) says Redline owner Howard Tanner."
You are simply wrong about 11 percent.
Sometimes a car has more hp than is published.

Re: How much HP from an 02-04 Z06 with Bolt-on Mods

Your joking right ?
Your taking what a car rag and venders profit from making bogus claims

So what your says is GM, SAE, Feds and others are lying about the Corvette engine output specs and to boot are claiming is people spend $20,000 less then a Z06 yet really the 435 HP LS3 equals almost what a LS7 is ?

Now we know your problem in this thread quit reading marketing hype.
Yea real surprise
