Highest HP out of a ZR1 to date!!
Just finsihed installing our complete REAPER package on Andrew Alepa's 09 ZR1 Corvette. We achieved 752rwhp and 740rwtq on 15lbs of boost and 93 Octane. You can see our setup is a little inefficient due to the boost dropping to 12.5lbs at the end of the pull. We have a few more tricks up our sleeve to try and keep the boost steady at 15lbs. If this thing will stay at 15lbs of boost at 6500rpms we should see 800rwhp. Keep in mind this thing is on 93 octane unlike alot of other ZR1 build threads I have been reading lately. Enjoy!

Very nice !!!! What headers were used ?? Could you post what the Reaper pkg consists of ? Obviously head work from the looks, cam, headers, clutch. Was that the stock AIR BOX, and is there a CAI available for the ZR1 ??
Can't wait to see the vid at home. Damn firewalls.

Id like to thank the guys at LMR for taking their time and giving me what I wanted. They were very professional working on the car and even put it on the showroom floor for 2 months while the heads were off. All the research on the car finally paid off and was done right the 1st time. The factory LS9 heads were done by none other then "Slick Rick" McConathy from NRC. I couldn't be happier then I am to have 750+ on pump gas and drives and sounds like a stock car with the exhaust closed. Thanks again guys, can't wait to pick it up 2 morrow. I guess I have to pay for it now, damn.

Ricky is the man. How is it that I have never met you ProStreet 632? I grew up in Friendswood and now live in League City. Anyways, very nice car and awesome numbers. Absolutely love the ZR1's. Hands down the best factory car built, IMO.
