Very nice numbers. The stock 09 zr1 i dynoed only made 525rwhp.

REDIMIX

just what i said i own the company!!!!!!!!!!!!!! I started the company with my partners nick and jose.

I know its clear, but some are probably thinking you "have" american racing headers, as opposed to you OWNING the company.

At least if you had even the slightest hint of information in you're profile people wont go around asking you weird questions, but again 600rwhp for a bone stock ZR1 is not realistic at all - YES YOU GOT THE NUMBER, no doubt im not saying you;re lieing, but its not realistic.

Tell us the results when you put the car on the other dyno you mentioned, would probably clear the doubts

REDIMIX

As soon as i put the car on a different dyno you will be the first one to know the results. I hope your wrong and the dyno is right or i will have to apoligize to everyone.

I don't know if all Dyno's are the same, but the one I have used, had the operator bring the rollers up to speed, in the gear you are making the pull, and you have to feed in an engine rpm number. If the number is off by 50 or a 100, it could change the outcome. Is this correct or not?

KILLER06GT

Maybe your SPRAYING it just a little

Just like I WAS

stkjock

/\ or a lot??? like you used to Mike

zeshawn

Dont worry, I hope im wrong either, but my car and many others cars wont make close to this power in stock form

REDIMIX

made the same power at the vette docs dynojet. Now we changed the lower pulley 2 more pounds of boost 642rwhp and 652rwtq how about that.

stkjock

nice Dave - will we see it out in the AM?

It is only a # guys. Any given time the numbers might be the same with his dyno,your cars,same time.As long as all cars are bone stock.We all know what the zr1 will do on the dyno.We all just want to think ours is the Biggest. The Old Man

Nice ZR1 but the supercharged LS2 Vette was fast.

3 Z06ZR1

Don't **** yourself a coated hesder is better all the way!

3 Z06ZR1

His ZR1 puts out no more or less than the rest of the stock ones! Dyno's are for tuning, Sometimes they put out a bogus number

zeshawn

what else did you swap, headers, CAI any porting/polishing?

I dont know but you're numbers seem way off, id like to think that 2more PSI would net 40+ rwhp, but LPE claims 40 BHP from 3-4psi of boost.

Tell us more about what you have on the car right now

stkjock

well I am sure the tune with the pulley helped on some of that gain.

zeshawn

sounds right, by just looking at the gains, ~40ish RWHP from a pulley and tune over a stock car sounds right.

Guys read the OP. Yes it was a happy day. For the dyno that is.

commanderzim

My Zr1 put 572Hp 470Ft-Lb and that with a cam, a lower underdrive pully and headers xpipe and corsa exhaust. Granted thats on a Mustang dyno that is very conservative. when was the last time that dyno was callaborated? your numbers sound high
