Default Procharger Cam

What would be a good cam to run with a Procharger at 10psi and still see some good gains without the Procharger? It will be a year until I will be able to get the charger but it would be nice to see some gains this year. Mid 12s is just not satisfying me any more.

I plan on going with LPE's GT2-3, and I'll probably order 2, 1 for the z and the other for my bone stock 5.3 silverado

Sounds a bit expensive. But then again that is Lingenfelter for you. Nice lift. The duration and LSA are not much different from stock is that what I should be looking for? A cam with higher lifts but pretty much the same on everything else?

What kind of gain do you think I would see without the charger? My guess would be about 20rwhp.

I ordered Thunder Racing's Blower Cam:
224/227 .563/.569 114 LSA to replace my TR224-112, to go with the ATI D1-SC I am installing mid April. I am leaving the 918 springs in along with the Ti Retainers and hardered push rods from the old cam since they only have 6-7k miles on them So we'll see how well it works out soon

If you are swapping cams, you may want to look into that other stuff as well: springs, retainers, push rods, and possibly an oil pump and timing set.

What do you guys think of this:

116 CL
intake: .335 exhaust: .335
Total lift: .570 (intake) Total Lift: .335
.212 duration .216

How would it perform?

Way to small.... wouldnt even be worth the time or money spent to get it...... I had a baby 212/218 .522/.529 in mine and i wished i had went bigger fron the start...

You both can go with a 224/230 .575-.585on the intake and a .585-.595 on the exhaust on a 114 LSA..... Never just replace the cam and not change valve springs........... go with a good set of springs and a new set of pushrods and you should be fine..... it will make plenty of power on motor to tide you over till you install the blower...

So, do you recommend a specific cam or do I need a custom grind?

I'd go with a cam that was around 222/224 intake, 228/230 exhaust, for 10 psi and a 6500 rpm shift point. The more you push the blower the wider split you want. But you have to be careful about running too much intake duration because too much intake will raise your power peak to the point where your power band could end higher than where you want to shift a car (or a car with a stock bottom end)

Would you be satisfied with mid 11's? A D-1SC at a "mere" 8 psi laid down 479 RWHP in my stock internal '02 Z28. I've only had it out to the track once, but I ran 11.71 twice, back to back, and hitting the rev limiter (4.10's) at about 1100 feet. The car is easily good for 11.4's, just need to bump my limiter a tad and roll out on slightly taller tires, which I now have.

Is a 12 degree split too much? I was thinking for a blower cam like 216/228. My other choice with less split would be 216/224.

I would be satisfied with mid 11s with the cam only. Without the blower and without touching the engine, not even an LS6 intake I will run a high 11. So mid 11s with a cam does not sound bad. But I will not be happy until I hit 9s. But that is a long time down the road. My goal is to knock off 1 sec every year. This year it’s to hit 11s.

Senior cam designers have said to run more split with race-oriented builds. 8-12 degree split stuff would be considered more race-oriented. But in our scene we tend to push the envelope so we are all race-oriented.

Oh and to the guy running the B1; Some cam designers indicated that they would start out with single pattern cams for 5-6 psi setups.

I am running a FMS/ Cam Motion 230/236, 115 LSA = 3.5 degrees of overlap at .050. I think it's +2 I can't remember it's in my notes.

I'm looking at a custom cam from FMS spec'd at 220/226 560/565 115. Not pure raced oriented, but moreso than most blower cams. Sort of a mid sized cam.

ATI D1.

Comp also has a 220/226 564/569 114 cam that is close t this worth considering, IMO.
