F/I Cam experts-Stick with LS6 cam or 224/230, 114 lsa for 346 forged LS6 D1Sc motor Have a lead on picking up a decent blower cam COMP 224/230, 581/591 lift, 114 lsa, for a stock cubed forged LS6 blower motor I am planning to build for my ECS D1SC Procharger setup that will see between 10 and 12 lbs of boost.
If your a f/i cam expert you already know that a stock 02+ LS6 cam makes great power on and off boost and makes for an excellent cent. supercharger stock cubed blower cam.
I LOVE the low end torque that the stock LS6 cam makes off the boost for normal driving and of course it makes big power on boost; howerver, i prefer an aftermarket cam if its going to make sig. more power without the car feeling like a dog off boost. and don't mind the extra hot rod sound of the aftermarket cam.
QUESTION THEREFORE is: Do I just keep running my stock LS6 cam for the new forged LS6 blower motor or will the 224/230 cam, 114 lsa, 581/591 lift cam make sig. more power off boost and still not feel sluggish down low (off boost).
Question number 2: Will the stock LS6 cam make more torque down low off the boost stop light to stop light for normal driving vs. the aformentioned blower cam.
Question number 3: Is there another cam you recommend that will fit my goals for this motor which is max power on top on boost and not losing anything down low vs stock LS6 cam (off boost).
Thank you for informative reply!

How can you measure low end torque in a car that stock doesn't even hook in 1st gear, you must be pulling a small trailer around.

And for low end torque...just select a high gear, and put your foot down. It does matter.
For an auto car, or a race car....it may not, for a manual, its very important IMO, and a manual road car...even more so.

If you like having your low end grunt stick with what you have. The 224/230 cam really shifts the powerband up higher where you wont be as much.
I'll take more low and midrange anyday.
just add more boost and have that nice rock steady idle.

Currently useing a TRAK cam from Thunder. I was a nitrous setup,..then found the blower. Bought a 2 piece cam cover,...and reinstalled my TRAK cam, just to see what would happen.
I truly can't complain, even with my little 42's maxed out at that time. Anyways...here it is. Car sound crazy at idle, and runs like a champ around town on a stock gear. The midrange is nasty.
580,510 on 8psi and maxed out 42#'s

I don't quite get your reply, especially since you don't state what your cam specs are. If you don't mind give the specs so we can compare apples vs. apples and stay on topic here!

Yeah a big cam with lots of overlap could be a beast in the mid range, and just gives up some power at the peak. It would be interesting to put a turbo on our project Camaro, as it's a 240/244//112.

Actually a tight LSA will lose little power anywhere inn the usable rpm range and pack a lot more in the upper midrange. The main tradeoff is idle vacuum and quality. Race car, no big deal, street car, kind of a big deal.
Be interesting to see engine dyno tests with a smaller tight LSA cam and larger wide LSA cam on a centri blower LS1.

defo....there was a massive thread on ls1.com.au ages ago about the same topic... and they did claim they were going to do tests. Nothing ever came of it though. Which I thought strange.

simply giving you a dyno graph, of a 346ci motor, on about 8 psi, and a "NON-BLOWER FRIENDLY/BOOST freindly camshaft"....that is actually for me, perfect.
.231/ 237 .649 .598 on a 112
...and I believe I stated that I have no loss of torque, or driveablity. The GRAPH, was given for your reference, so you could see how the camshaft performs.
The TRAK cam is a common cam, therefore the reason not posting the original specs.
...anything else?
