Pontiac G8 2008-2009 - G8 GXP - 490 RWHP N/A - Video Inside

We recently installed our L92 Stage 2R MAX camshaft in a customer’s 2009 G8 GXP (6-speed manual). We’re very happy with the results. The car was baselined stock and made 351 RWHP / 360 RWTQ. When finished, it made 490 RWHP / 442 RWTQ…. A gain of 139 RWHP / 82 RWTQ! We haven’t had a chance to do any fine tuning on the street yet due to the current weather conditions, but I’m confident it will drive very good for having a camshaft this large.

Modifications were as follows:

Livernois Motorsports CNC Valve Job
Livernois Motorsports L92 Stage 2R MAX Camshaft
Livernois Motorsports LS-Series Dual Valve Spring Kit
Includes: Livernois Motorsports Dual Valve Springs, Titanium Retainers, Valve Spring Locators, Locks, & Valve Seals)

Kooks 1 7/8" Longtube Headers & X-Pipe w/ Cats
Factory Catback
Rotofab Cold Air Intake System
Powerbond U/D Pulley
ARP Head Bolts
GM MLS Head Gaskets
NGK TR6 Spark Plugs
Synthetic Oil Change w/ Filter
Professional Installation
Livernois Motorsports Dyno Tune

Strong. Well done.

Very very nice Rick Great work.

do you think with an aftermarket Catback you'll gain those 10hp to get 500rwhp??

wow, just plain sick!

Thanks for the replies!

I know that when our GXP was stock we added only a Corsa system with no other mods and no tuning and picked up 10 RWHP, so it's possible.

what would that cam kit do in the g8 gt?????

White looks great. Impressive power

-Nathan

nice numbers and doesn't sound to bad either

what would that cam kit do in the g8 gt?????

probably the exact same thing that is sick i'm glad livernois finally posted up one of the big cam cars or i have just been missing them thanks guys if i had a shop and this customer turned his back for a second i'd have that catback on just to see LOL guess thats why i don't



Livernois FTW

I'm pretty confident that you would have to notch the pistons in GT for this camshaft. You'd also need a converter for a GT, and I'm not sure how drivability would be with an auto.

damn i was looking at the g8 forum and there was member saying that the stage 1 dod delete kit was a hassle for dd and that the idle would drop really low off sudden braking...

I guess it comes down to personal preference. I think the stage 1 cam is pretty mild and if I had a G8 GT, it would be my cam of choice. The stage 1C is even more mild, yet makes good power and has near stock sound and drivability.

-Rick

very nice

Cost?

Stock clutch ??? Or did you have to upgrade it?

nice power. sounds mean.

Cost?

Cost for this package installed and tuned is around $6,999.99

Stock clutch ??? Or did you have to upgrade it?

Stock clutch, it didn't slip at all, then again, it only has 900 miles.

yall wouldn't happen to have a clip of a G8 GT with the 1C cam would ya or a dyno graph

I have a video of that cam in our GXP, but I don't have any videos of a GT with that cam. I know a guy on the G8 board installed the 1C and AR 1 7/8 Headers and exhaust system in his GT and made 400 RWHP.

and the dyno graph from our GXP stock vs modded.

You can drive in 6th gear at 35-40 mph at 900 rpm's and there's no bucking or jerking, it drives likes it's 100% stock.

Mods are:

Livernois Motorsports L92 Stage 1C Camshaft
Rotofab Cold Air Intake System
Kooks/Livernois Custom 1 7/8" Shorty Headers
Corsa Exhaust & Integrated "X" Style Crossover Pipe
Tuned by Livernois Motorsports

Nice!!!

Hey Rick

the LS9 cam is 211*/230* @ 0.050" .562"/.558" LSA????

1C is 218/229 .600/.600 117.5

would you stay the 1C would be a good conpairable blower cam ......

here is the deal i wanta do a little to the car soon but will not be able to put a charger on it for a while so i see the 1C does great without the power adder

i just don't wanta have to buy another cam when i do the blower and this is a daily driver that gets raced very very min

The 1C works very good N/A, but would be a great cam for a blower.

SOLD so if i order the DOD delete kit instead of the Stage 1 L92 Camshaft i can sub it out for a L92 Stage 1C Camshaft
:)

i'll be like a ginny pig :) first 1C cammed G8 GT then add the blower and another first :) i can deal with that :) i'm excited

I can swap it out for you. Our cost on the stage 1C is more, so it would add $30.00 to the price. If you pm me your name, you can order online and I will substitute that cam or you can call me at 313-561-5500 ex. 2123.

We've sold quite a few mail order for GT's, but I have yet to see any results other than the one I mentioned earlier. We did a normal stage 1 cam, Kooks shorties, Corsa Exhaust, and a Rotofab with a Maggie 1900 on a GT and it made 530 RWHP at 6 lbs.

-Rick

well i would like to be getting the DOD delete with 1C cam and full exhaust but leave the factory mufflers and yall can tune it to see how it does and then hopefully if all goes well 6 months to a year (probably a year being realistic) add a blower 6 to 8 psi and yall can retune it thats the plain

your call good idea or bad idea Optional CNC Valve Job??? factor in i'll be adding the blower in a short time

Sounds like a plan! They sound great with headers and factory mufflers.

N/A, it's good for 15-20 HP, so I would do it.

good then i'm gunning to make the order in jan. this month is my girls 2 year birthday and then with thanksgiving and chrismas it will have to be jan.
