EPS 222/226 vs 226/230, LS2 GTO
Ordering a Cam package and I decided to go with Geoff at EPS.
Car is a 2005 GTO, a4, LT headers, intake and catback.
For a number of reasons I do not want to put a larger stall in...I don't want to get into those reasons here, but I have decided to do 3.91 gears with a stock stall knowing that even a 3200 stall would perform better at the track.
Given that, which cam would you recommend? I'm thinking the 222/226 would be better suited with the stock stall and still pull pretty good for a street driven vehicle that will probably only go to the track once a year....This is a car i want to mess around on the street with, so i want a strong snappy setup that rips on the street and doesn't have to spin to 6800rpm to get the most out of it.
In the future I may also consider an intake manifold (typhoon probably) and ported 243's (AI most likely)
What do you guys think?

Either one should be fine. If you dont have to worry about smog i would go with the bigger of the two. Geoff and Pat G should be able to shed more light as to what works best than any amateur on these boards though. Lol

I would even concider a smaller cam, I have dynoed, installed, and had tons of success with cams with 219 @ .050, They typically gain 40+hp and street manners are wonderful. Part throttle torque is awesome, so much that Its what I installed in my truck! Not to mention they a easier to tune, use beehive springs, and pull to 6200-6500RPM without a problem.
Here is one two steps down, a 215/223. No torque loss, Its actually up 40lbft down low with lots of power gains! Win-Win.....

In this situation I would go with the smaller. Stock stall, track once a year, wants snappy feeling = smaller cam.

I ordered an EPS 222/226 113Lsa +2 cam from Geoff. At around 3700lbs I think it should be a good torquey cam in a Ls2

Thanks for the responses guys. It's nice to get an opinion from someone who understands that even though you are modifying a car some people want more then the absolute best 1/4 time. 226/230 with a 3200 would no doubt be faster at the track, but I think the 222/226 with 3.91 (3.46 stock) Will be a ton of fun to mess around with on the street and probably FEEL faster while keeping stock like driveability (stalls have more disconnected feel to me)....I am after all only trying to impress myself with the mods.

222/226 Cam
Attention OP
I have a G8 GT / A6 & Stock Converter that I getting ready to cam as soon as my new heads show up.
Patrick G. did my selection with the 222/226 115 LSA for a stock converter.
I know others that have done the exact mod with good results but do say you need to keep the LSA around 114 to 115 for best results.
Contact Patrick G. and you'll be confident with your plans.
Good Luck!!!

I've had a Lunati Voodoo 222/228 in my M6 GTO for 5 1/2 years now (installed March 2006) and love it.
The 113 LSA is better for a stick, a wider LSA is usually better with an Auto (or so I've heard).
No matter what you do... Have fun with it!

The higher LSA gives a wider powerband in addition it starts sooner. For instance a 115 LSA may have a powerband from 2500 -6800 and a 113 LSA from 3000- 7000. Thses aren't actual powerbands I am just showing you an example. Of course there is more to a cam than just LSA but basically the lower the LSA the higher in the rpm range it will make it's best power. That doesn't mean that it won't make power down low, but the smaller cam will make more down low and better average power in the operating range of most street driven cars. I would still consider installing a very mild converter , maybe a 2800- 3000. I had a Vig 2800 in a stock z28 and it drove completely stock until you got in it and it would flash higher. My wife drove the car for about a year and never knew It was any different and she did plenty of stop and go city driving in it.

You are correct sir. I typed it wrong for sure. Basically what I was trying to say is the lower LSA will have a narrower powerband that starts later and have to rev higher to use the power. The higher LSA has a wider power band that starts lower. Correct? The torque falls off earlier in the narrow LSA but the HP doesn't if other supporting mods are there such as intake, other parts of valvetrain etc, right?
