What's the smallest pulley I can safely run on 60lb injectors, meth injected and second front mount intercooler?

 

prob 2.8 lol more of a matter of opinion ? though

 

if you run enough meth you can run a small pulley.

 

You shouldnt have any problems as long as you have enough meth.

Just keep an eye on your injector duty cycle. You don't want to drive your injectors them too hard to where they are constantly open or your PCM will hate you. Recommended IDC is anywhere below 80%. GMS2 runs at 110% though, so take that with a grain of salt. If the car runs with no knock and you arent noticing any particular symptoms, it should be fine.

What kit are you running?

 

2.8 with no meth, any size with meth.

 

I run a 2.5 on 60's with 10 gph 50/50 meth. 85% duty cycle

 

im alsao running a 2.5 with 60's

 

So no problems running the 2.5's....seems pretty small

 

x2
what boost levels are you seeing at a 2.5 and with what exhaust mods

 

2.6 tvs pulley + ported head, 60s, enough water/meth, 80% by 7200

 

What does everyone consider enough meth? 10 gph? 12gph?

 

any other opinions?

 

zrated89 runs a 10gph nozzle and ran some very impressive times.

 

what power do u make on a 2.5 tvs? Talk me out of going turbo

 

From what i've seen 350-375whp

 

On stock head?

 

Yup. He's an example what WSfrazier made. On a 2.7 yet.
