H/C/I D1SC dyno predictions
Previous combo made 430/396
-Stock bottom end 346
-Cnc 243 heads milled .030 for 11.1 CR
2.08/1.57 manley race valves
-Ported Fast 92/92
-TSP 228R .600/600
-1 3/4 QTP headers
-Magnaflow cb 3" exhaust
-Fast 36 lb injectors
-Mosier 8.8 12 bolt 3.42 gears
-Built T56 M6
Adding
- D1SC 4.5" twin intercoolers w/8 rib 7-8psi
- 60 Lb siemens injectors
- lonnies dual in tank pumps
-Alky control methanol 50/50 mix
What do you think it will make? Im assuming i will lose a couple pounds of boost due to the efficiency of the fast and the heads. Think it will break 600 rwhp?

If your making 5psi @6000 rpm you either have a really efficient setup or your bleeding off boost. The 4" crank pulley should put you up to 8-9 psi IF stock. Im trying to gauge what crank pulley i should use because i have the heads/cam and i was thinking of going with a 4.5" but maybe i should go with the 4" and hope for 5-6 psi.

Well just wanted to give an update being that its finally June and just got the procharger on the car. I took it for a few data runs with the meth injection and 4.5" crank pulley. The car made 3 psi @ 3000 rpm and 8.2 psi @ 6500 rpm but made one freak pull of 10 psi @ 6500 rpm on one run. Anyone want to venture a guess to why that happened? Also, anyone want to reguess hp estimates?
I have a base tune by Frost @EFI. The car feels very under powered actually feels naturally aspirated, so im wondering if once i get a dyno tune and adjust a/f and timing if this thing will evolve into a beast. Any thoughts?
