Sounds like a good setup, cant wait to hear how far you dip into the 12's!

any mods needed to mate the 8.1 injectors with the tbss rail?

I went to the track last night and ran a best of 12.7@105. my best time so far, before the stock 243's and tbss manifold i ran a best of 13.1@103. there was a 15 degree difference in temp at the track that really helped
|
congrats!!! does it "feel" faster

Nice times! is this on street tires or did you get some slicks?
|
thanks guys! the run was full weight, system, spare, 1/2 tank, with street tires. i know the temp decrease helped along with the higher cr. im sure the intake/tb helped some. my cr is around ~10.2 . the stock 243's bumped me up almost 1 point in compression
|
Then your CR should be closer to 10.5 Did you adjust your tune at all when you did this swap?
|
tune adjustment was the first thing done. what formula you using to get that cr? with a stock .53 gasket i was getting 10.2
