iron 8445s , stock bottom end (rods mains caps crank pistons and all the stock bolts ) thats right no girdle studs or steel mains ,
flat tappet cam ,stock rockers /shafts /pushrods ,
stock untouched intake
on a TT chip
went back last night (changed the wastegate spring from 5 to 11psi ) adjust alky controller internally and adjusted the fast program .
now ive got much better spoolup but with more boost at launch than i can handle with 275/60 DRs and it comes on much much quicker than before
so my 60s sucked as all i got was tire spin even coming off as low as 7psi
best run was only
1.67 slipping through 1st
4.49
102.89 6.87
127.05 10.71
capped up through the mufflers
race weight 3498
so next outing will have to be on slicks
