Pulleying a YSi strictly for 93 pump gas

**Pro Stock John** · 12-27-2005, 11:35 AM

I'm selling my custom YSi setup to a guy who wants to start out with a 93 pump gas setup.

I'm currently running:
Vortech LS1 crank pulley
Vortech 2.85 blower pulley
Griffin A/A FMIC
Vortech Mondo Bypass
Vortech YSi
LS1 348ci 8.2:1 engine
Peak of 754rwhp @ 6600, but did 680rwhp for 144mph passes
3400 raceweight
TCT 4500 converter
3.50 gear
28W

I'm thinking 3.33 pulley for pump gas, what do you guys think? Or a 3.4.

Ut Ohhhh......Turbo???

I would say a 3.33 should be OK with a safe tune. Unless a small Cu In motor?

What Cu In motor will it be on?

I'm pulleyed at 8.25/3.15 at the minute, 8.7:1CR making 16psi at 6300rpm.

I am using a small quantity of water/meth via aquamist, but it is small.

Your lower compression, bigger cam and potential larger pulley should make for a safe pump gas combo if my own is anything to go by ??
certainly as far as staying detonation free is concerned with proper tuning.

I'm not sure the size of his motor, I will check. I'm selling him my 236/246//114 cam too. I think I'll get a 3.33 for him then. I'm surprised Bob was so weird, you'd think a guy trying to sell parts would be more constructive. :)
