After seeing the impressive results with jc05e46m3's thread
here, we were eager to get our JB4 installed and get some numbers. With cooler weather and some race gas (97 octane blend), we were able to crank out some pretty impressive numbers. An 1/8" NPT fitting was plumbed into the charge pipe to get boost readings.
Running Stage 3 configuration on 97 octane fuel, stock exhaust. Runs are maps stock (91 octane), 1 (mild boost, 97 octane) and 7 (E85/high octane map).
