I've have had dual exhaust since 2002, three different setups. They tune just fine.

Would changing the cam to a larger than stock (like listed above 214/220 .559/.566 115) produce more boost or less?

there is alot more factors than just the cam, headers will help bleed alot of boost of due to less backpressure, even cats play a big role.

A bigger cam than stock will help you make more total power.

so would the cam in my sig adversly affect anything when running it with a turbo? Just curious because if it doesn't sell in time then I will have to run it for awhile until I get another.

I am running a 230/236//115.

Aren't you running an ATI tho? I thought the turbo's like a different profile?? Thanks

I'd recommend this one:

LPE LS1 GT2-3 Cam - 207/220 .573/.580 117.5 CL - Excellent supercharger/turbocharged cam with a smooth idle.

We sell these for 428.99.

With the above cam, would it lower my boost or bump it up? And how much loss or gain in #'s?

100% stock except for sig below

Phil,
Isn't the GT2-3 cam ground straight up? Meaning it has no advance or retard? If it's got a 117.5 CL it sounds like it's a straight up design. I looked into that same idea with Comp. For my 383 stroker/ 14# D1SC setup we came up with a few cams. Here's what we came up with:
Cam 1: 222/230 .566/.573 115lsa +2
Cam 2: 224/232 .568/.575 115lsa +2
Cam 3: 222/230 .566/.573 115CL (no advance)
I liked the idea of the #3 cam cause it will have a smooth idle and with little overlap it will build killer cylinder pressure, which will build torque early yet still have killer top end. If i do decide to go alittle bigger on duration on the intake, something like 226 or 228 i would have more advance built in but maybe go on a 116lsa. Something like a 226/232 116lsa +4. I don't want to delay my power band too much with the larger cam. I know if i was staying with stock cubes the Lingenfelter cam would be very interesting to try. Just a few ideas i was thinking up.

I'd have to grab the cam card to verify but I believe it is ground straight up. The nice thing about this cam is the split duration/lift and 117.5 centerline. The intake duration is very low with a much higher exhaust duration which is perfect for a boosted application. You shouldn't loose any boost with the cam and the idle will be very smooth. This is the same cam Ligenfelter uses on their twin turbo cars which have a great reputation for drivability and power. The ramps on the cam are very agressive as you can see by the lift figures compared to other cams. It would also be very easy to get this cam to pass emissions etc.

It would really suck to install a cam and loose boost and power. Of course, depending on your blower, you could just change the pulley to get your boost back if that is an option for you.

Look boost is not that important a supercharger with a set pulley araingement will put out the same amount of air at any given RPM it is the heads and cam and intake that determine how much boost is present. The cam and head will just help you move the air more efficiently so you may see a drop in boost, but you will not see a drop in power ETC... So don't look for a specific number on the boost. Just look at the basic principles force more air in you need to get more air out that is the reason for the larger exhaust duration. You don't want too much over lap on a cam or you will be blowing your air and fuel out the exhaust unburned ETC... If you install a cam or heads ETC... you can pulley up or down to get it back to where it was before the install of these items, but you will also be making more power at that point and will need to be tunned for such. Hope this help you understand what some of the specs of these cams are trying to do. Hey what do I know I am just quoting what has been taught to me for years about basic principles.

I know what you mean..I've installed a few blowers and cams over the years in my f-bodies. The right cam is as important on a blower setup as the heads are. Too much intake duration will cause the intake charge to actaully over fill and bounch off the piston and revert the charge back into the intake which kills power. Small duration with a good amount of lift ( as long as the heads can flow it ) and as little overlap as possible trap more air/fuel in the cylinder making the most torque and hp. That GT2-3 cam is very small yet it's used in a twin turbo vette making 650 hp If i was doing a forged 346cid motor instead of a forged 383 stroker i would use the Lingenfelter cam in a heartbeat. Killer idle quality, killer tq, and ease of tuning it in a A4 makes it a great cam.

BlackNite,
I agree with you that it is a good cam I thought about it for a while but then I came up with the specs for my cam while looking at what everyone was offering ETC... I wanted to hear my cam too. I like mine and it makes good power too sounds mean.

Oh yeah i know what you mean, I love the sound of a cam. That's why i'm going with something in the 224/232 ..570/.570 115lsa range for my 383/blower setup. It should give alittle lope but not be too big for the blower.

I have the TR224 114lsa in my car now. I'm planning on getting a vortech kit (~7#) and spraying with water/alky. Will this be a bad setup?

Thats exactly what I have. I am just waiting to install the new heads and blower. But I have alot of nick nacks to buy for the install.
