Caliman93230 · 12-09-2010, 10:33 AM

hey guys i was looking to get a cam for a whipple s/c. I was thinking of getting the ls9 cam but was also interested in the GT9. any body have installed these cam's. I have ls3 with a whipple no other mods making 598 rwhp and 546 rwtq i don't want to be having to change springs very often. also I wanted to be able to run stock exhaust and intake to pass smog, and use LT'S and CAI intake at the track.

Given your Info the LS9 Cam may be a best fit for you but not necessarily the best Blower cam for a Whipple.

A buddy of mine has headers, cai, whipple w/ 3 7/8 pulley and a LS9 Cam and put down just over 600rwhp, through an automatic trans! Matter of fact Ted tuned it. LS9 is not bad at all but like Ted said there are better cams matched for the Whipple I`m sure.

ted has his new smooth idle blower cam, but you will need to change valve springs with it. i'm actually considering that cam or the gt9. i'm gonna install the whipple later down the road.

The Emissions thing and NO Valve Spring thing really limits you on cam selection.

As far as the GT9 being smog friendly, I think that's going to depend on what state your trailer is parked in

Weve been camming LS motor cars with top mount twin screws for about 5 years now. I have 1 specific cam that, in my opinion, is hands down the best cam for these cars. Last saturday, on an LS3 Camaro, we made 678rwhp 606rwhp, at just over 7psi, on a Maggie!!!.
Honestly though, virtually every single Camaro we have done, with this cam, has made 660-720rwhp with 8.8psi or less. With nothing more than the cam kit, and exhaust.

Our lift is just at .600" at its peak, and the car drives, and idles perfect. Its got just just a tad of lope; just enough to know its cammed, stays within 7-10% of your current mpg, and has absolutely perfect driving charicteristics.

I believe we have idle videos, but I also think their on youtube. There is a member that has a thread on here with our cam, videos, and dyno graphs. His name is "Stealth Camaro". With this cam, you will have to replace your springs at the very beginning, but you will not have to do it again. We run them on XER lobes, so your valvetrain stays safe, and happy.

I dont think we are allowed to post up prices or anything like that in discussion threads, but if you decide you want it, you would refrence TPE-G5.

Call, PM, or post, if you have any questions.

In my opinion, the LS9 cam would not compliment the Whipple. Not only is it a 211/230, but its got a 121LSA. The Whipple is to efficient, and capable of flowing significantly more air than the blower on the ZR1. So what you would end up with is an extremely hard hit, but it would struggle to really climb hard in the RPM range. You want a nice flat torque curve, and as straight up up hp as you can get. The wide LSA, low intake duration, and extreme exhaust bias, is going to give a very broad, and flat power curve. You want a heavy exhaust bias on these motors due to the head design, but you need to factor in a few other variables, as well as the efficiency of the blower.

IMHO

I dont know that the GT9 specs are, so I cant comment.

SRT10KLLR · 12-09-2010, 03:12 PM

The GT9 cam has the following specs: 215/247 .629/.656 121 CL

BTW, how would your cam(TPE-G5) do in a turbo setup?

Im interested in getting a cam that can get the good use of LT's and a CAI on 91 octane, and if i had to go back to stock header and intake would not have an issue to pass smog. I now its allot to ask but its hard to play here in CALI :(

Total_Perf_Eng · 12-09-2010, 07:39 PM

Well, our cam is at home with LT and catback, with a blower. The amount of airflow the blower and motor is able to produce, requires the ability to remove it. This is why the LT and catback work so well.

Smog passing has mostly to do with tuning. So basically, as soon as you needed to smog, I would suggest you had it tuned again. But tune it to pass, not for power. Swap back when your done.

We've seen larger cams pass, but weve also seen smaller cams fail. So as long as you have a compitent tuner, you'll be fine.
