Put The 92 on the Dyno Last Night
Ran it with the valet key on and off to checkout the secondary operation. The only non-stock part is the flow master cat-back exhaust system.
 Here is the run for my 95. More mods including headers, exhaust, porting and Haibeck chip.

Re: Put The 92 on the Dyno Last Night
Aw, you should've let me know! I would have gone to watch. :-)
Looks healthy. I've been looking for an opportunity to take mine to Arthur's dyno, too. Maybe I'll go later this month.

Nice #'s... My 91 did 335RWHP, with just flows & stock chip also. (324 bone stock 11k miles on it)

Re: Put The 92 on the Dyno Last Night

Re: Put The 92 on the Dyno Last Night
Mike Ebert did it I believe...

Re: Put The 92 on the Dyno Last Night
Yes Mike Ebert did the work. Very nice job. All I did was port match the heads to the injector housings and clean up some gasket issues. Didn't pick up much HP, maybe a few. What I did was not worth the effort. When I get around to replacing gaskets, servicing injectors and Fuel line o-rings, I will see if I can track down Mike to do the same thing to the 92 intake and housings.

Re: Put The 92 on the Dyno Last Night
Update: Flash forward 5 years..... I can not believe it has been 5 years already. The attached photo is of a dyno run I did in 2018 after porting the intake, injector housings and port matching and blending the head ports myself. It took the better part of a year to do this. Along with the porting I also locked the secondaries and had Mark H. adjust the fuel curve on the chip. Pretty good increase in power and torque for just letting her breathe better. My guess is a set of headers with no cats would put me close the 95's performance of 400 RWHP. I chronicled the whole porting job complete with flow data on the corvette forum ZR1 tech section. I wish there were a way of transferring to this forum.
Tested at 371 rwhp & 362 rwtq
