355/854 12v

[AHall]

Ran the gmc on the mustang dyno at school. made 13 total runs. best ended being fuel at a little less than 3/4 and 36psi. Lost some torque when i slid #0 full forward. This was with very light load because the load software is broken or something. hp and tq were at 70mph. i would think if the dyno could load better i could see 45psi like i see on the street and torque would be in the 2000rpm range like it should. im guessing it'd do around 400hp on a dynojet that could load right. ill run it again when i get my gt4094 and 5x0.017 injectors in. not bad for the first time on the dyno tho. 355/854:Cheer:

I took the .89 a/r put the .99 exhaust housing on my gt3788 and man what a difference. Power used to be sluggish and wouldnt begin to clean up smoke. Now it will easily break the duals loose in 4th gear and cleans up alot better. It has easily twice as much thrust as before. By switching the housing it made more of a difference than going from a stock turbo to the garrett. SOP dyno would have to be at least 50hp id say much more tho.
