the vehicle is a 2005 GTO,

a buddy of mine has a cam that is 236/244 592/592 112lsa... I can have it for DIRT cheap.

would it be possible to get near 425rwhp with this cam? to me it is a bit iffy...and fuel mileage would be ****... more then the cams listed below.

otherwise.. I was looking at the HPE-S cam or the VRx5-6 cams...to make sure I get there.



your thoughts?

 

yea you should be able to get there with full boltons and a good tune..


and my friend with an 05 gto gets pretty decent gas mi with a cam comparable to that one.

 

Id be really happy if she made more than 400 with that cam, I'd be really really happy with 425.

I have all the bolt ons already.... wouldnt take long to throw a cam in her.

also if I do choose my buddies cam. would you go with dual? or the new .625 revised 918's?

Check the cam for wear as it is used. If the cam is good then go for it.

Comp or PAC .600" behives with Ti Retainers and locks should last a while with that cam (20 to 30k before needing to be replaced).

Use an adjustable push rod to get the correct rod length (so the valvetrain geometry is correct).

With stock 243 heads and a full intake / exhaust bolt on setup 425rwhp should be do able.

Tune it properly to optimized everything (WOT performance and daily driving). Don't forget to remove Torque management!

Don't forget that the Stock LS2 clutch (if it's a M6) will start to wear out if you push it with that kind of power to the ground.
Or if you have an automatic that a new converter will be needed to get the best out of that cam.

Also be carefull of wheel hop as the added power will make it easier to break the cv's, drive shaft, or half shaft's.

Good luck and enjoy the upgraded goat.

 

First off, need to know if your car is an A4 or M6. Also, what bolt-ons do you have exactly, and who is tuning it? My M6 car made 395/415 with full bolt-ons (minus UDP and RR's) before the cam. I would say 425 is definitly possible with the right combo and tune.

 

With an M6 05 GTO i've seen 420rwhp made with 228/228 camshaft, UDP, Kooks headers, borla exhaust.

 

cool thanks guys! I've decided to upgrade to the HPE S cam...

my car is an M6, with a monster stage 3 clutch, tick master, pedders....etc...

 

i see no problem with what you want to achieve. From what i've been seing you will be fine.

 

I've actually looked into this and it cuts real close with a good tune and seems to be okay on gas mileage, who buys a 6.0 and is looking for perfect fuel economy anyway haha

 

If you want gas mi,I got a moped for sale.lol Your goal will be easy with boltons and a cam. I did it on a ls1 and got it to 463hp with good heads. Good luck.
