24psi spike, drops to 18psi at redline

 

So if i run cosworth 272's with stock rev limiter i'm not going to need upgraded springs and retainers right?

 

Yea, but its still highly recommended

 

interesting.... so since i already have them in and everything is running fine.... and got tuned by ivey...

lets just say i plan on upgrading them in the future.... do i need a retune?

 

Went with cosis installed last weekend, and I love em.

 

soo like my question was... if i install springs possibally retainers do i need a retune?

 

i made 360hp/375trq on 23lbs with all stock FMIC,IC piping, Maf pipe with cone filter. and 3" TBE, Comp 272's. not lopey enough for me.. really dont want to go wirth 280s tho...

 

I personally have GSC S1's, but have been told by a very popular tuner that the cosworths can make more power as they can take more timing...Reason I didn't go with the Cosworths was because I was on stock valvetrain, and while the difference is minimal the cosworths are slightly more aggressive and I personally didn't want to risk it, so I went with the GSC's, and they're great. Stupid friggin mid range with great top-end too...

 

Obviously i like s1's by my sig, and plus im suprised no one had mentioned greg yet. He is the best person in the customer service department i have ever dealt with. Big thumbs up to him. Customer service goes a long ways in my book when deciding on a hard choice like that.

The s1's are sneak sneaky to so i like that even more.

 

can any one pm where i could ge the best deal on the S1's

 

pm greg directly for gr8 customer service and gr8 prices .

 

I have an Evo 8, but got a great deal from Justin at JSC for the S1's.

 

You getting cams FINALLY!!!

 

All of the IX guys with Cosworth cams are you running with upgraded springs
and retainers?

If you don't mind me asking, in general how much does a cam install usually cost?
