We'll I finally installed the meth kit and 10lb pulley at the same time. The truck pulls a lot harder and gets to 8lbs boost right at 2000rpm and reaches 10lbs at 3000rpm. The truck feels insane off the line since it reaches full boost much sooner. I have not done WOT yet as Im waiting for HPT to arrive. At 60% throttle it was doing 0-60 in 6 seconds according to the crappy ATAP program. So the question to you experts is .... Can I get to 15lbs? and what do I need to get there?

 

I don't know 15 lbs, but with a FMIC and your meth kit you should be able to do at least
13 lbs on 93 oct pump gas.
now with the FMIC, your meth kit, and track fuel at a higher oct, you should be able to do 15 lbs easy.
I think parish is close to 18 lbs with his meth kit, FMIC, and track fuel on his turbo system.
I know his boost numbers are allot higher then everybody else's on here.

 

Nice. Dont see a lot of the KB's on here, but with the FMIC I would deffinetly expect that thing to be fast. With the meth you might be able to get 15, who knows.
Good luck.

 

I make 18lbs on the street no Meth and on 93

 

Hey V,
I have tryed getting ahold of you a couple of times, I am getting ready to do 8psi and had some questions for ya. I think that the number that I called was a work #. Get ahold of me.

 

That's awesome! You must have the FMIC.

 

Been Quite busy. Will Call you soon!

 

The top end has dramatically improved. I can feel the engine ripping the tranny on the 1/2 shift. Looks like the 4l80 is next on order of priority. I am dreading it because of the work involved. Any Advice!

 

What size pulley are you using to get 10 psi? I know on my whipple a 3.0" pulley on my 5.7LS1 makes 11 psi.

Thanks

Yellow

 

Im using the 3.125" pulley.
