Yeah it was a 3". I think the guy said he had a stock mustang, but was making a lot more power than that lol

 

Maybe i missed it but what was your boost number after smaller pulley/tuning?

Congrats on your newfound power, damn i wish i had E85 here!

 

With a 3.1" I run about 11psi. I think thats about all my 112 can do without turning into a furnace lol.

 

Nice!! I bet she moves out real nice!!!

I dont get into the "heat" thing with the 112's. Im mean unless your hotlapping all the time its no biggie.

I think i would like my next project to have a 112 , cause damn i love that whine!!! And i rode in a 5.3 S10 with a 112 and it was scarry fast, a real rocket!

 

Yeah it moves pretty good, always puts a smile on my face when I can tap the gas and spin the rear tires whenever I want

Speaking of heat, how bad do you think it would be to drop from a 3.1 to a 2.9? I know the E85 will make it much better than pump gas would.

 

Only one way to find out bud!!!

I would give her a try , you got the fuel and a dyno to use, DO IT!

Damn boost is addictive isnt it? !!!

I wanna try to get 12#s out of my setup next, hopefully without having to go 8 rib.

 

I run a 2.9, and I see about 10 with my heads headers and large exhaust.

 

Man I couldnt agree more. I remember when I got the truck I thought 5psi 'stout'. Things sure have changed in the last few years lol


I think I might try a 2.9 on my 4.8. I dont have the heads or lift you have but it if I keep my A/F in check I know Ill be fine. Im going to the dyno again in a little over a week with my new driveshaft, Ill post new numbers when I do.

 

Plenty of time to order a smaller pulley

 

is he high speed balancing these shafts he's "building right" for you? not balance, but high speed balance.
