That was really close to what you were expecting... The turbo adds 62hp and 133lb-ft. Not bad for a pretty stock truck with a turbo... I am really curious who all went and what Racin put down? Tell hi to post it up already. Lol

 

haha quite a jump! if that doesn't sound too impressive to ya,folks.remember we're talking old school low hp idi's (no offense there '91! good numbers!)
that difference is a whopping 71% more HP and 147% more grunt!!
putting it this way,really shows the increase.......if i did that right lol.sounds a bit crazy.someone better check the math lol.

you didn't say what it took for boost to get so much increase though '91.i think it's a bit higher than one would run without head studs.
nice going!! you can't knock that much increase via just a bolt on kit.impressive.

 

That last video was a bit smokey huh lol

I hit 17-18 psi on the turbo run.....scary I know

 

I am surprised you didnt blow a head gasket...

 

I do 30+ on a daily basis.... and 40+ regularly
