Just got finished with install and dyno tuned.
7.5 Crank
2 3/4 pulley
18# boost
dual focus pumps
dual #8 fuel pump outlet
#8 line to rails
65# injectors
SCT 2800 MAF
93 octane..
Almost 100 tq difference at top end.
1.7 gave up at top end.
The 2.2 pulls hard until you stop. Got to hang on at higher rpm.
I'll get some datalogged results including timing and AIT.
BTW- the stock computer would not allow more fuel after a certain point. We were 14 a/f .. Though 30% more fuel and added 20 fuel pressure no change in results.
Switched to an 01 GT box. All is OK....
I am sure I have some belt slipping up top.
We wanted to see how things ran with a conservative tune. Timing 13 low, 15 mid 16 at the high end.
Fix the belt slip, little more timming, run it to 6500 sure to get 640.
A/F around 12.
Some 100 octane turn up the volume 700 would be getting close.
