Corey Henderson

Well I trailered My 90 ZR-1 and made the trip from Houston down to Corey Hendersons shop saturday. It was about a two hour trip. And I met the man himself. He has a nice shop that they are already outgrowing. But as I pulled up that dyno was going the whole time with about five Corvettes. Three Z06's and a couple of Cobras lined up out the back door ready to be dyno tested. I also saw 4 other ZR-1's in the shop. A white one. And two black 91's that had been pumped up to 600hp. And an admiral blue one. So I had no doubt I was in the right place. And Corey let me know that if I ever decided to get more performance out of my Z that there is so much more untapped power you can get out of the LT5 that in its stock form does'nt even begin to scratch the surface to let him know. He thinks I just have a couple of bad injectors. He said the dual mass flywheel is designed to absorb vibration from the engine and transmission. So if you have a bad injector the first place your going to hear it is in the flywheel. That's why he said that I'm hearing that slight knocking that comes and goes right where the flywheel is. So I can't wait to get her back.

you have found one of the best that i know for fact . i drove 1500 miles one way to have him do my car . he ported my injector housings and plenum put in 410 gears and dynod the car which with the restrictive flowmaster exhaust made 409.9 rwhp and 373.3 tq. after designing my own exhaust for it . took it to a dyno here and she made 426.2 rwhp and 380.8tq . the car has run a best of 11.88 2118.76mph @ famoso on mt etstreet radials . that iis hp and times most other get with full porting inc heads . what he does is take the time to treat each and every car like its his own zr1 . its his atten to detail that gets that extra hp. he also owns a zr1 .to top it off his pricing is very fair if on the low side (hope he doesnt see this hehe ) first class all the way. i just got a callawy for the wife and will be doing the 1500 mile drive to have him do what the boss (wife ) wants . wouldnt take my zr1 to anyone else
