I've been piecing things together, so far I've gotten a jokerz full tilt with 2.3 ,a 9.17 lower, 2inch tsp headers, low side fuel kit, and heat exchanger upgrade. Not looking to do heads and cam at the moment if possible. Just seeing if im overlooking anything.

103 throttle body and Rotofab Big Gulp.

Unless you are going to use methanol, a 2.3 and 9.17 is a lot of pulley and will spin the blower too much making more heat. I would either do 2.3 upper with stock Lower or stock size upper with 9.17 lower.

Yes, forgot the 103. That's been my concern with that lower. But without the lower am I sacrificing much?

I don’t think so. If you are tracking (road racing) I wouldn’t do any pulley. If roll racing then do either or. The 2.3 will spin slower than the 9.17 but will produce less heat. My “theory” run the 9.17 lower and stock size 2.5 upper.

I have cam, headers, meth, 103 TB, Big Gulp, 2.3 upper, and 9.17 lower. I’m planning and scaling back to 2.5 upper and removing the meth.

After thinking about it, I think for now I will do the put the ported blower with the 2.3 on 103tb, big gulp, Headers, HX, and tune.
