What is a safe pulley size to run to keep it under 450rwhp? I think the PSI range is like 7-8...

I'd just go with Whipple HO kit and be done with it if I were going to supercharge!

This will leave you right around 435rwhp (members of the whipple crew have confirmed that). And then you have a much more upgradeable system that runs more efficient plus the roush is only a 1.8L where the whipple is a 2.3L system... I personally will be getting the Whipple HO kit and running a 7-8psi pulley. That way I know if I ever want to go crazy with the system I can, but if I don't I'm in a perfectly safe range.
Even if you detune the kit, simply installing it kills the warranty.

I can speak from experience. I thought xxx would be enough, then just a little more, a little more, infinity. I was absoluetly sure about my decision too.

LAX,
Check out Tousley Ford in MN. An FRPP Whipple HO is $6400 shipped. All Whipples drop ship from Whipple in CA.

It's alot cheaper to get the HO kit from the start instead of adding the big boost kit later.

Yeah i didn't mean you specifically on that, just in general any time you ask about a roush charger someone jumps in and says they are junk and can't be upgraded. Sorry if you thought that was aimed at you, i didn't mean it to be. and tousley is the shiznit on price for the whipple if that is what you want.

Lol, i am ready to order my R90 tomorrow. Just to prove myself right or wrong, i am going to start a thread talking about ordering the R90. see how many comments it takes before someone says it's junk get a whipple.

I know a bunch of you all are all going to claim that the stock engine with it's cast crank, cast rods and pistons not to mention a compression ratio above what you would use for a supercharger can handle the 550 hp... No one day the pistons will swap holes before exiting your block. I know the 550 is crank hp not rear wheel hp, but it's still more then that bottom end can take. A lot of us with Ford Lightnings been there done that. It will hold the 435 hp but not much more.
Okay, let all the people with a buddy running 500-600 hp everyday for years start the attack.
Good Luck
JE

PS: There is a reason the 435 hp kit gives you the 36,000 mile, 36 month warranty.

Just because he has had no issues does not mean anything. How conservative is his tune? How hard does he run the car?

I personally would not risk it which is why I am going with the Edelbrock or Roush kit. Either is more than enough power for me
