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

Great writeup and strong results. Gotta love the numbers the AI combos are putting out.

This makes me mad that your car with nothing but a cam made almost the same power as my stroker on the same dyno lol, DAMN YOU V.

I bet you didnt make 400 RWTQ at 3000 RPM though =D

haha lets do the heads on that thing and you'll make way more lol........nah i only made 345ish at 3k lol

haha yeah we will see... great power though

Nice results. Now let them do the heads!

Off topic, but who grinds AI cams?

Great results OP! Gotta love AI's work. Get those heads ported for some insane power.

From Phil at AI, "We regularly deal with 10-12 cam grinders and often a few other obscure sources. In the end, the grinder doesnt really matter, it is the lobe characteristics that matter."

If you get bored with it shoot me a call. I've got a great Cam for that motor that when tuned right drives very well and makes sick power. Just did one in a A4 05 GTO. Cam only with headers made 430hp/400tq through an unlocked 3600 stalled tranny. Easy 450/460rwhp through a M6 car on my dyno (480-490 hp on Dez's)

Goal of this cam is a mild lobe design that will be durable with mild valvesprings for 40k+ miles and make decent power while still retaining great maners.......obveously more could have been achieved with more agressive lobes and valvetrain components but that wasn't the scope of this project.........490wrhp cam only LS2 on any dyno are big numbers....do you have these numbers cause id love to see them? also do you have a dyno graph of that cam you are speaking about? I'd like to see the hp/tq curve.....peak numbers sound good and sell but arent always the fastest as you know

as far as i know they are using comp right now.....

Cmon now, we all know mid range torque means nothing Mike!

Slowhawk

iTrader: (12)

It's all midrange.Peak at 6200-6300rpm. But I know you wouldn't do it..LOL

490rwhp is a loose dynojet like Dez's. Mine are a bit lower.

iTrader: (7)

if you have a graph id love to see it........also i have a hard time seeing a 30rwhp difference from dez's DJ to yours with a stick car.....ive seen consistant cars that have dynod on yours as well as dez's and there is around a 5rwhp difference auto's are a different story espically with large stalls......id be happy to take my GTO up to your place and do a test to see.....

Slowhawk

iTrader: (12)

At Dez's the dyno was very incosistant between hot/cold days. Expecially when it was under 45 degree's out. Remember I worked there for many years. But the dyno is just a tool.

Can't remember the last time I even posted a graph on here..LOL

Phil @ AI suggested that same cam for my car with the 226 port job on my 243 heads. My goal is 450 HP to the wheels.

a-low

iTrader: (26)

Wow! How well will that cam workout on a 3800 stall full bolt on ls1?

quik95lt1

iTrader: (7)

that would be easily attainable......id expect to see 460-470 if i ported mine......



and to show what i mean by drivability and a mild lobe cam i took this video the other night driving home........keep in mind its about 25* also......1100rpm up hills and cruising no problem no buck no hesitation all day long.....car drives like stock.....it truly is a mild cam designed to last a long time and drive everyday regardless of the weather.....car was tuned by me in Speed Density in Closed Loop with EFI Live.....

Advanced Induction

Indeed. There are dozens of cam grinders out there, and a great many have a handful of lobes I think are an ideal compromise between their relative aggressiveness and the time area they provide. Sometimes they can provide a cam, other times I mix and match lobes between vendors, and other times I alter an existing design to taste & come up with something new.

Mac is referring to our cam page, which roughly outlines my POV: http://www.advancedinduction.com/LSX...BilletCams.php



I can only surmise that the marketing theory that one is born every minute works for you. How about a real cam comparison - eliminating the multitude of variables that an actual vehicle adds to the equation. I am happy to overlay actual data from whatever lobes you think are appropriate with Mike's current grind should you care to be measured up.


Ahh, another characteristic of the predatory vendor - I believe we're establishing a trend. "I own the brand of dyno that is known to put out the most consistent results... but mine just happens to be "tight" and other shop's DJ's are "loose.""



Almost 14,000 posts, no data to support your assertion, and desperate attempts to catch the coattails flying past you like we're enjoying here? Perhaps they're born more frequently than on the minute.

Guys like you are what prompted that cam page I linked above. I thought the flow # games were bad, but little did I know that selling a camshaft these days has become more an exercise in theater than quantitative analysis.

Most any cam in that size range is going to make mid 4XX's with the 226cc head on a stock short block. The difference is going to be in RPM headroom, component longevity, etc.
