After a couple false starts and some down pipe fabrication I got it installed last night. Put some miles on today around Denver(5000') and have a few observations...

5th gear 10 sec pull

Stock hx35/12
Comp 3x5
Max Boost: 31 psi
EGTs quickly climb to 1400 and then go on up to 1600.

Comp 5x5
Max Boost: 31 psi
EGTs quickly climb to 1500 and then go on up to 1650+.

B1-2
Comp 3x5
Max Booost: 34 psi
EGTs slowly climb to 1100 and top out at about 1150.

Comp 5x5
Max Boost: 38 psi
EGTs slowly climb to 1450 and then fall back to 1400.

So far I am impressed. Spoolup is very little different. Seems to have lost a little low end hit but comes on harder from 1800 on up. I think I need a little more fuel to turn this thing though. I thought I would see 42-45 psi boost but with Mach 2s and Comp I may not have quite enough fuel at this point to make 45 psi. With stock 35 I could hammer it for a few seconds before EGTs started to get a little high. With B1-2 EGTs are now a non-issue no matter how long I stand on it. I think some Mach4s are in my future
