what size pulley you running and how many lbs of boost are you getting?

 

I run a 8 rib dedicated drive with a 8" overdrive damper pulley and a 3.7 blower pulley. 17lbs of boost with no intercooler just lot's of Alky.

 

My 60's got me pretty far, however I've seemed to have lost control of them at this point. I'm running a magnafuel 4303 pump 80 psi in boost and my injector duty cycle was 138%.


Your running a bigger motor and bigger blower than me, so I could see you needed quit a bit of fuel if you turn it up.
I'd go straight to some 83's or bigger. Probably bigger...

 

Guys I really apprecieate the help. I just ordered a set of 80's I just hope I can turn them down enoough at idel. I still have to pass a sniff test. But with the DFI I should be ok. I will post some pics as I start the conversion
