Hi Malcolm! Compression is about 9.2. Never CC’d the chamber. 9.2 is based upon Wiseco’s spec sheet based upon -6cc. The dyno numbers are from VMPs Dynojet dyno.
This is a question for your tuner but yes the Gen 3 will work well with your stock motor. Keep the boost and timing conservative and you can run 92 with no issues. You can have a separate tune if you add more octane for a race tune.
I have a Teksid block, 9.5:1, return system, 80s, twin 465s(base pressure of 60) with a VMP TVS 2.3.
Power is 740 at 22lbs on E85. 800+ with a 75 shot.
The 80s will work but are not ideal. 1000s or 1300 are a better choice.
Thank you! I was amazed at hitting the 5s. Hope I can do it again!
Unfortunately I did miss a gear. Based upon calculations it could have been a [email protected] pass. I like my 57 Chevy wheels! LOL!
