LS9 camshaft with GMPP heads.

[Juice2SS]

OK all. I changed my cam, removed the radius intake manifold, removed the VMAX TB, removed the Yank 3600 SS converter, and had the car tuned at ADM. Car lost 24 HP before and after. For all those who want to remove AFM, run GM parts, and keep drivability... this is a good setup. I'll be posting the before and after measurements later. All I can say is I love a car without cam surge. After driving the car for the last 9-10k miles... I started to hate it. Car would buck poorly at street lights. Died completely when I would exit the highway or do a low speed roll. Truly a painful car. I'm back to loving it again. The LSA goes on next. Can't wait for dependability.

Sounds like wrong cam or wrong tuner or both.

[62nalide]

Yeah buddy !

[Juice2SS]

Cam was tuned by the creator.

I've remember your posts from here and there and it seems that your more of a budget build kind of guy that like milder modifications. Looks like you wound up with an aggressive cam that you shouldn't never had put in the car. A LS9 cam is a huge jump from any aftermarket cam that would need a 3600 converter to work to its optimum. Sure I'm the kind of guy that would run a 3000+ on the stock L99 cam but most other people wouldn't. Its all in knowing what you want and sticking to it to the end result. I've had 11 previous Camaros, I know. My most loved build was the one I stuck to my game plan and didn't deviate from it.

I'm just happy the car runs the way it does now.

I let the budget aspect go long ago. Wanted to see how far the car could be pushed. It went to the edge pretty much. New path for the car with the LS9 and the blower. Sometimes, hindsight is 20/20. Should have stuck with my original plan.

I agree with you on the most loved build guide. I had a 98 before this car that was an LS6 swap. Car got 30MPG on the highway and outran my father in laws GT500. Miss that car to this day. lol

Your going to make a lot of power.

[Camarojt]

Nice! Glad to hear your happy with it.

[Rhino79]

Glad to hear you are happy with it. Never heard back from you on getting back up here to dial in the tune though?

That same cam is in several cars with no issues (SS3 VVT) not real sure what was going on with your setup, needed to log it in person and see.

Good luck!

As we all know big cams make great power. No news to any of us on that one. But like juice said the driveability goes to the crapper. Everyone who does a cam or upgrades really needs to know what they want in the end. It is easy to get wrapped up with what everyone else is doing and jump on in with the masses. Then to realize what you dont like about it and its already to late. I had a stage 3 btr cam in my other car. But it also needed a stall to drive ok. I knew that when installing it. I was ok with it. I liked the sound. But without the forced induction it was a waste at that time. Car ran hard and was fun. Dipped into an 11.97 with stock tires. But it was kind of annoying at times. Like 5am going to work. I know i woke my neighbors up quite often. Lol. But what im getting at is it really worth the extra 25-30 hp in the end. Maybe if you are looking to get every last bit out of you setup. Ya maybe . But 95 percent of us dont live at the track. Most dont even dd them. I can say that i do dd mine. About 50 miles a day. My new car has a 417 gt9 cam lsa blower ported heads etc etc etc. Built by adm performance. Yes it has a stall in it. But it runs and idles way better. Does it make a lot of power. Yes. Is it fun to dd. Yes. Will it scare the poo out of people. Yes. It will spin the tires at an 80 mph roll. My point is driveability is way nicer to me that a little bit of horsepower and a constant lumpity lump driving around in it everyday. So i can say this to the op juice2ss. I know where your coming from. And you will enjoy your car a lot more if you install a blower with that ls9 cam and heads rather that that big obnoxious cam.

Nice, good luck with the 2nd build, are you adding a ZL1 blower at some point too?

I think it would be interesting to create a context for what these cams are like:

Stock GM L99 195 Intake/201 exhaust @ .050
LPE LS9 211 Intake/230 Exhaust @ .050
GPI SS3 VVT 228 Intake/243 Exhaust @ .050

Could you share what you dynoed before and after?

I just had the GPI SS3 VVT cam and Bo White ported heads installed and I like it alot. Last time I dynoed was 2 years ago, just headers/ underdrive/ airbox/ tune, and did 367 RWHP. Since then added 3.91 gears and a 3200 stall and went 11.8 best MPH of 115. My 2015 goal is 10.99 or quicker with the new heads and cam.

Ryan and I have been tweaking the part-throttle downshifts, like when you coast to a light. One of my local buddies likes it when the RPMs come up a bit as it shifts down, get a big of an engine braking effect. I like something more like stock, so we've lowered the MPH at which each downshift occurs. But I also have 3.91 gears, so 3rd gear for me at a low MPH is still quite driveable. Even when I had my old 2000 Z/28 with the TH400 and manual valve body I'd tend to shift down when I was nearly at a stop. But since I have my own copy of HP Tuners, I like being able to drive the car, log mentally what I like and what I would change, and then go in and say drop the MPH for the 3-2 shift change another 2-3 MPH.

That's the intent. Have two tunes. Street and fun... I like the idea.

You know far too well how long I've been having fun with it. Thanks for being a sounding board for me to whine to like a 10 year old girl. lol

7 1/2 drives each direction kind of suck with full schedules. Flying to and from Arkansas was enough of a lift when dropping off and picking up the car.

Oh I have seen it perform very well in several cars. That's why I was thoroughly into getting the car updated with tunes from afar. Wasn't much that needed changed as I replaced lots of stuff. Sometimes, eyes on are better. I couldn't break away for the time for the eyes on fix and was hoping the remote stuff would work. Alas, it didn't. Easier for me to be local. Car has been at ADM many times and I doubt that will change. Track season opens soon. We all have things to accomplish.
