LS2 GTO w/ Advanced Induction 226/234 Cam Kit – Pics & Vid I'd like to share some results of a recent cam install I did on my daily driver LS2 GTO, I installed an Advanced Induciton cam kit w/ a 226/234 .600/.600 112LSA cam in the car recently and had some great results.
The car is a LS2 06 M6 GTO Red on Red with the big ole boat anchor 18" wheels on it heres a pic of the car.....
The car previously made 373rwhp and 367rwtq with only 1 3/4" Stainless Works headers, gutted cats, a Bassani cat back exhaust, and a K&N Cold Air intake. I also tuned the car with EFI live. With the later addition of one of the older first FAST 90mm intakes and the stock throttle body the car ran 13.0 @ 110mph with a garbage 2.1 60' on stock Bridgestone tires.......
After having such great luck with Advanced Induction on my LT1 Camaro (see sig) we decided to pop one of their smaller street oriented cams into my daily driven GTO to see what it would do. The install was a piece of cake; Phil at AI supplied the correct PSI Valve Springs, Shims, and Pushrods to make the install a breeze. Two friends, 8 Hours, a 6 pack and pizza later the car was running
I tuned the car in Speed Density mode with EFI live (MAF is still inline on the car however, just unplugged), car idles awesome at 850-900rpm and sounds great also with an aggressive sounding idle. You can cruise down the street at 1200rpm in 6th gear with no bucking or surging at all and the car will also just put along in traffic idling in 1st gear ......torque is excellent in the 2-3krpm range feels much stronger than stock and the cam really woke the car up above 4500rpm in the HP department....... a second gear roll on from 35mph equals tire smoke without a burnout first.
Here’s a video just putting around the neighborhood.....

So now for the good part...........dyno day.......
After messing with some fueling i wound up at a very conservative 22* of timing and 12.7AFR to make the most HP and TQ made 422rwhp at around 6200rpm and 397rwtq at about 4800rpm great power for a street oriented cam with great driving characteristics. All pulls were made at 185* coolant temp with a 85* IAT temp.
Here is some video of the dyno pulls:

Here are the dyno graphs from the pulls:
As you can see below the area under the curve on the graph is awesome
Overall the car picked up nearly 50rwhp and 30rwft/lbs tq peak.......the most impressive part to me is the broad torque curve making over 350rwtq by 3200rpm and over 400rwhp from 5300rpm to almost 7000rpm....one of the most important things i know from being involved in drag racing for quite a while now is builds that focus on area under the curve in the usable rpm range are the builds that are fast....not necessarily the ones that make the most "peak" power....so seeing this kind of power curve has me excited ...this means with the T56's shift extension the car will never fall below 400rwhp while rowing through the gears which is nice......the flatness of the torque curve from 3500 all the way out to nearly 6500 is also great to help get this 4000lb tank moving!
All in all I’m pleased with the power it makes, and the way it drives, and most importantly the way the car actually pulls on the street I’m a stern believer in racing cars not dynos Thanks again to Phil at AI for producing another great product for me and soon as the weather comes back around and my local NH track opens up I hope to see some 115+mph traps with this 4000lb boat

Yea I think he and I were looking at a 228 cam with a 112 LSA to go with his 226 CNC'd headwork and a FAST 102 LSXR. Can't wait to get home and get the build going, the results of yours are certainly giving me something to look forward to!
