Finally getting my ZR-1 back from Corey's!!!
On the flight down right now to pick up the Z from Corey Henderson's. Following is a brief list of all the work that was done:
OBX Long Tube headers installed Fuel Injectors installed (from Fuel Injector Connection) 4.10 speedo gears installed C4 beam plates Removed secondary throttle blades new plugs Updated top end port work Dyno tune Final numbers were 360RWHP, which while not earth shattering is way better than the 300RWHP that I was getting. Corey said it didn't look like the secondaries had been working in quite a while. He also said the he would guess that I could probably gain another 20HP with a better flowing exhaust (currently have a Borla) and maybe a 160 thermostat. I was also thinking that I should probably MAT sensor relocation too. He said he was about 2.5 degrees short of where he normally can set the timing to without knock. I didn't have time to really talk with him in depth as he was finishing up and getting ready to go to BG. For any of you interested in OBX headers, make sure you ask him his opinion if you are there. If not, I will request a full email opinion on them and post it on here later. Can't wait to get there and drive the car. Should definitely be a lot of fun now! |
