Hey all,
Ok, I just got off the phone with Lingenfelter and asked them about maxxing my car out. Currently I have the following:
Magnuson Intercooled Supercharger (kit)
3.1 pulley
LS6 CAM
Morley Hardened Push Rods
(i think they also did the springs too)
Dual Chain
FLP Long Tube Headers w/High Flow Cats
Corsa Indy (Pro Tips) Exhaust
BPP Vortex Cold Air Intake
and Injectors

I want to max out the cars potential with a STOCK BOTTOM END. Please understand I dont wanna crack the engine open. There is only 44k on this car and I wanna make her do everything she can on everything she has.

Ok, so Lingenfelter told me that dropping to a 2.9 pulley would be the max that the stock bottom end could take, and then he asked if I wanted a stock like idle or if I wanted it more aggressive. I said I dont mind coming off the street setup just a little bit and being more aggressive. His suggestion was to put an LS9 cam (ZR1 cam) in the LS1 setup (stock heads with some upgrades as stated above).

Just wondering what you all though.
Will this max out my performance the best while keeping the car's stock bottom end together? I dont want to risk grenading the engine. Do you think the LS9 cam will do the trick for me, or should I have done a custom grind. According to Lingenfelter, I would be happy without going with a custom grind (and understand I NEVER said anything about price).

All constructive inputs are welcome (please note: if you input, please have something to back it up. please dont just say i love my cam without saying why and what it does over the rest)

 

The ls9 cam uses a single bolt on the cam gear and a ls1 style cam uses 3 bolts. The ls9 cam is .562"/.558" and 211*/230* @ 0.050" which is a bit small imo. I would go with a different cam.
How much power does your car make now?

Thia is a ZR1 cam in a LS3 Great power stock like idle.

 

The LS9 camshaft's specs are close to the camshaft that is in my LPE TT650 engine.

 

and?
(not being a smart ***, what i am asking is what are you really saying? that its a good cam or should do the trick over the grinds that are twice as much?)

 

Sorry, should have been more descriptive. The LS9 camshaft's specs are similar to an LPE custom camshaft that is/was used in there upper end FI builds. It will have a very smooth idle and won't be peaky like some other grinds. Could you pick up more HP with another camshaft, probably. But, the LS9 camshaft is very civilized and still will make some impressive power.

Here's a dyno chart of my 346ci TT at 8psi boost.

 

The cam he is talking about is there GT7 cam 208/230 lsa 121. When I did my build LPE said that I should use this cam and it does cost less. Hope this helps.

 

Yeah my LS9 cam cost me a whopping 160 bucks
Hopefully that with the 2.9 and a Centerforce Clutch and a good tune and I will be hitting the streets hard

 

according to lingenfelter it's a 3 bolt cam.
