Roush Series IV question

[Rotzs99]

Bothering you guys again.

How much boost can you run with the 3.0 pulley. What is the max boost the series IV can handle?

I'm running Chicane's pulley (not sure the size) and I'm seeing just shy of 12 lbs of boost.

I run the chicane and i have a smaller one yet a 2.8 from pulley boys i never used. the key with these cars is getting those act's lowered. For one a chicane intercooler is key im getting one this fall i tested a car with one and it saw a easy 20rwhp. Remember if you drag race vs a dyno pull drag race you have to do a burnout rev stage a car bang the tires for 4 gears so you can imagine the temps vs a 6 second dyno run in one gear. intercooler and some sort of big intercooler tank to put ice in is key.

LFP has a heat exchanger and a bigger coolant tank(supertank) I have both plus the Chicane intercooler the cars IC temps run about 40+- cooler..I have a 03 saleen.Also the opening on the supertank is big enought to add ice if needed...

yup but there is gaps between intercooler and intake under the blower so some hot air goes right into the motor.

Thanks for the input guys. Im not really thinking of getting a saleen. But my dream right now is a 01-04 GT with saleen IV. IMO kenne bell is overplayed, so with a built motor and a series IV im just wondering what kind of power is possible.
