Compression Ratio: 9.25:1 (too low)
Motor/Displacement: 346 LS1
Amount of Boost: 10psi
Type of FI: Turbo
Meth Yes or No: Yes, sort of.. -20* WWF
Max Power: around 550 based on weight and MPH
Verdict: NEED more compression! LS2-3 are around 11:1 and for daily drivers, around 10-12 lbs run GREAT. The next motor I build will be a fairly high compression FI motor running about 10-14 psi.
Old school thinking was add boost, lower compression. They drop it to 7.5-8:1 and boost 10psi. Sucks big time out of boost. Now we've pushed that up to around 9.5:1 and 10-14psi. Getting better, runs pretty good out of boost and even better in boost. I for-see more and more 10-11:1 and 10-14 lbs of boost and lower timing to be better for all around driving day to day. If your gonna go BIG race setup, then maybe a 9-9.5:1 20+psi of boost with race gas or alcoholic/ethanol and medium timing. Theirs my .02c on it.
