[kwt chevy]

heloo

How are you guys

I am Wilshere from Kuwait I want to advise me






i bought a zr1 ls9 cam what do you think its good ? I really want cam with no sound I want to look like a car without cam how much it will give me hp

And i heard about the gt11 cam Is it good ?

What needs to be installed with the gt11 CAM must change Springs in l99 ?




Excuse humble English and thnx

[Mr. Wyndham]

The L99 valve lifters will need to be replaced with almost any cam replacement. They are designed for the Active Fuel Management system that shuts down 4 cylinders on light load.

do you have an automatic or manual? You can't put the ls9 cam in the L99 without removing the lifters.

True. I don't know that I'd even consider it on an L99 car personally, but that's just me.

It's an easy and common upgrade worth about 20-25 rwhp in an LS3 however.

No springs or pushrods need to be swapped either which makes it a very economical hp/cost mod.

Best of luck and keep us posted!

l99 mean auto ha guys give my some information

Not sure on the LS9 cam, you might need to delete variable valve timing (VVT).

Also, you might need a torque converter for the transmission.

The LS9 cam and the GT11 both have very wide lobe seperations made best for use with positive displacement forced induction. Use of these cams in a N/A will result in poor performance as compared to cams made for N/A.
There are also many things to know about the VVT and AFM before jumping in. This thread might help some.

I beg to differ about the wide lobe separation angle being only good for forced induction. Check out the LS3 cam comparo by GM HiTech. The GT-11 Had some of the best all around #'s in the test and was one of the ones with the best street manners.

[PoleCat2SSRS2010]

If that's what what is preferred. Great. Then there will be missed benifits sacrificed because the wider lobe seperations don't permit the better intake charge and exhaust scavenging from their lobe centerline locations.
If the GT11 is such a great NA performer then why are all the cam grinders making NA cams on 106 to 115 centerlines some with 0 to +4 advance?
Just saying that there are better options.

any videos of the LS9 cam in an LS3?

DIY?

3 bolt or 1 bolt?

[mrvenicess]

I am interested in the LS9 swap or some other cam that does not require new spring and lifters. Any links to that GM hi po comparison. What about the GMPP "big cam"? 20-25 hp increase would work for me on my daily driven LS3. Any thoughts?

[caverman]

I think that's the cam that ADM uses for their Stage I kit. If I remember correctly it's about 20 rwhp and you can't hear it. That means they won't know about it for warranty work either.

so, you can't hear the lope of the LS9 camshaft in an LS3? I guess that's what I wanted to know... I want at least a slight lope.

I just liked the idea of not changing the springs/rockers/lifters... and having something that GM designed.

Has anyone tried the GM hotcam? I know Robin L. at GMPP tried it and only got ~9 HP when the rest was kept stock... but I think it has a pretty nice lope... and maybe with headers/CAI/tune... it will get more than 9 HP net gain.
