iF anyone has ever had their car tuned and then retuned with cams on an 03 please give your gains and what cams. There are so many cams out their, i like HKS but i dont know anymore.
thanks

 

Based on what I've read people have been getting the most gains from comp cams on 8's.

 

whatever happen to revolver or jun's? but those require some headwork

 

yea sorry I was thinking about cams that can be run on stock valve springs.

 

definite gains of around 20-302whp...i personally love 272s and GSC as far as cams go...

 

im getting 272's but HKS or COSI? HKS are more, if they are better ill pay more, if the Cosi are getting better results, Ill be happy to pay less.
I understand their is a specific way they act throughout the power band meanwhile everyone just wants peak numbers which dont mean as much.
I just do not want to be unsatisfied with HKS if i pay they extra money.



03- HKS 272/272 or Cosi 272/272

 

yeah i went with gsc s1's and i love then, maybe you should read up on them

 

Stock cams I put down 300whp, with HKS 272/272 i put down 320.

 

i have bc 272 and i love them...havnt been to the dyno tho

 

I put down 343whp at 21psi and a boost leak with Helix V2 272 cams. I am upgrading to revolvers soon.

 

I have HKS 272 e/i but no direct before and after numbers. My tune was with basic bolt on and cams. My graph is pretty square in transition from TQ to HP. I enjoy them and they sound good.

 

Also have BC cams and love mine too

 

What kind of mods did you have at that time if you dont mind me asking? (I'm assuming that was before alky and the IX turbo) I am thinking i'll sit at around those numbers after i put in comp 280's 10.5 hotside and 02 housing this week.

I currently have a catless tbe, turboxs copy fmic, injen upper lower pipes injen intake, turbo xs ebc. and the supporting mods such as fuel pump clutch etc.

 

Revolvers have the best gains from what ive heard, but i also think they have gone out of business or something, but thats just rumors. GSC's seem to produce really good gains and seem to have similar characteristics as the Revolvers, but without head work. They both have 264 or 262 degree's, but their lift, duration and all produce excellent results. Average seems to be 30whp with the cams and a dyno tune.

 

The mods I had are listed below. After we fixed the boost leak we when up to 27psi and I made 359whp. I think the turbo was out of breath. My Helix cams will be up for sale soon.
