It's All About the Build
When this project started 3 years ago, my goal was to achieve a reliable 500 (SAE) RWHP daily driver. The last time the vehicle was custom dyno tuned by Justin at VMP Tuning, I reached 446 RWHP/427 RWTQ, still 56 RWHP short of my goal. Since then I have:
I know I have a few issues that prevent me from reaching that goal:
You can check my signature for a current list of mods. I should also mention that I do not have belt slip or all the other belt issues normally associated with manual transmission vehicles. Nor am I convinced that an electric water pump reduces parasitic load enough to even be measured at the wheels. I do not have any spark blowout issues. I am not convinced that aftermarket cams are required for a F/I application at only 500 RWHP. I already went the TCI SSF T/C route and at 425 RWHP found the lockup clutch to be slipping. Pulled the TCI converter out and went back to the stock converter.
Please remember this thread is not about track times as my vehicle will never see the track. It's about reaching a goal. As Chevy Killer mentioned in another thread: Start with a goal and stick to the plan.
So for those of you with more knowledge than me, which is probably most of you, what else am I overlooking? Please feel free to make suggestions.
- Changed the 3.2" (12 psi) pulley to a 3.0" (14 psi) pulley
- Replaced the 90mm Lightning MAF housing with a BA-2400 MAF housing (my 90mm Lightning MAF was maxed out at 12 psi)
- Replaced the 39 lb. injectors with Siemen Deka 60 lb. injectors
- Replaced the GMS coils with MSD coils
I know I have a few issues that prevent me from reaching that goal:
- My vehicle is an automatic not a manual
- My RWHP is measured in SAE not STD
- I am currently running FRPP shorty headers with a Magnaflow Catted X-Pipe
- 4.10 gears
- Lastly when my vehicle was dyno'd the last time, ambient air temps. were 99+ degrees
