To run higher PSI on a SC you will need to get a smaller pulley, not sure if anyone with a stage 1 has done that yet actually. Would be curious to see the results and if it overspins the unit.

I may be upgrading to the 1.5. I'll let you guys know if that goes through.

You may want to pm me I have a lot of stuff that is right up your alley.

As of now the Stage 1 is ordered, upgrading to 1.5 this afternoon once I call them. Oil cooler with thermostatic plate added to the order. Custom stage 2 clutch kit from Zspeed along with supporting parts (csc, etc). Working something out for some gauges lol. Anything else I may need? I saw some people including radiatiors. Doing research on that.

Again, I'm trying to build a powerful, [U]reliable[U], car. So if there's anything else you guys would suggest, let me know.

To be honest, this motor can use all the cooling it can get, especially FI. Half my costs were supporting the power. 3/4 of that was just on cooling. Yes, I consider meth as a method of cooling. So be sure you have your budget and another budget for "incidentals"... GTM won't steer you wrong, but what they recommend and what you need are two different things.

What would you suggest to aid with cooling?

Kinda depends on your location and how you use your car

A radiator at the minimum, maybe fans/shroud. Have the tuner set the fan temps lower through Uprev.

I'm in VA..it's actually starting to get chilly about now. In terms of heat it really doesn't get that bad. Might be high 90's with a ton of humidity in the summer.

Same here. like 404/340 i think is what it dyno'ed at last time i had it checked.

I honestly think you'll be fine for like 99% of the time with just the 25 row cooler. Sounds similar to Chicago weather. Only thing I did in addition to the cooler was cut slits in the fender liner right behind the oil cooler to help get some additional airflow through there.

What size pulley?

whatever came with stg 1 kit. 8psi

Guess I will have to go back and look at tuning mine out for 405. :p

Well, just got my full ceramic Southbend stage 2 clutch and flywheel, along with master cylinder and slave kit. Last couple things are the gauges and camber arms...and then I should have everything needed to do the install at once.
