The GenIII w/mods has a sbc ID blitz boost controller. We are removing this since we cannot get consistent boost levels.
Having the combination of a DFI and using a dyno w/wideband allows for the best results for finer tuning & driveability.
We did not use a helper spring for modifying the actuator. Will share the way we did it once there is consistent safe results.
The dyno log showed @29 psi on the run where we let out at 4200rpm (334rwhp/377rwt) 100 octane was used for that. We let out due to being on stock injectors. On the 100 octane pulls the leanest a/f was 12.5:1.
You should expect @300rwhp on 93 octane w/o a turbo kit or a dfi. You can review my other post results on my own street GenIII. (this car has run @ 300rwhp for the last 4 years on 93 octane daily driven up to 75 miles a day at times since the GenIII swap). I run 100 octane for insurance at the track w/higher boost.
After building a GenIII many years ago and seeing the the hp numbers soar on every level, I wouldn't bother building a GenII. In the past we consistently made 800rwhp for the street class NHRA and now have 1006rwhp with the Scion TC (expect 1200 rwhp once tuned).
