It's Finally Done!
Just to recap a little for those who don't know me. I've owned my 1987 Camaro IROC-Z with the 305 HO TPI, Borg Warner T-5 and 10-bolt 1LE differential for about 5-6 years. I run a tire, service, performance store and we have on and off played with the car to see what we can do to maximize the car as a bolt on only project. I had no sucess with the differential and modified the internals as well as created a few parts to strengthen the smaller axle shaft tubes to make a pretty darn bullet proof differential without moving to a 12 bolt or the Ford nine inch conversion (not to fond of putting Ford into Chevy or Chevy into Ford). But that's another thread all together!!!
So the biggest part of maximizing the car was Horse Power of course. Started off a couple years ago with a direct port nitrous injection system with a progressive controller and that was a lot of fun! After a lot of testing (lolo) decided to pull that in favor of a Procharger D2R system but found along the way the ATI has sort of crappy support, so we pulled the Procharger of and moved to a Vortech V7Ysi and that seem to be the best fit! Vortech was very helpful over the last year and a half with helping come up with brackets and a 10 rib pulley combonations that works very well! The biggest part of the challenge was fuel delivery! With the NOS system it was easy, just put bigger jets, with a supercharger it's all about EFI! Keep in mind I'm still using the OE MAF system and customized a 3.5 MAF housing last year to stay with the factory ECM.
If anybody has been reading my post about the stand alone FIC system I just fabricated up, they know there has been some issues on using this to suppliment my fuel deficiency epedimic. So did it anyway and just on the test drive it seemed to work pretty darn good, but the Dyno is the heartbreaker so we called in a appointment for this Saturday and off we went. I only had the dyno reserved for 1 hour and think with a little more time and tuning we could probably grab another 25-35 hp but after 9 full pulls here are the results and you be the judge.....
Keep in mind this is a stock cast internal, stock cast iron head motor.
459.13 HP and 479.22 TORQUE at 5500 rpm and 11 psi boost
For further info, feel free to post up or pm me. I tried to keep it basic, not everybody on forums are super techies or know tons of fancy achronyms and engineering techno mumbo jumbo. LATER GUYS
PS- NOW COME THE PURPOSE BUILT MOTOR CAUSE THE BOLT ON PROJECT IS OVER!!!! HOPING FOR 650+ YEE-HAA!
