BE CAREFUL WITH THESE COMP WILL TELL YOU USE AT YOUR OWN RISK!!! THESE ARE NOT SPECIFICALLY DESIGNED FOR OUR MOTOR THEY WERE RELEASED BEFORE OUR MOTOR WAS EVEN OUT, i got very in depth with comp on this one and all they could say was use at your own risk
And keep in mind...
Regular ECOTEC camsets will not work on the LSJ
So make sure if you order something it is for the LSJ specifically (or possibly the B207R used in the Saab 9-3 but since they are turbo may have higher exhaust lift/duration)
Technically it's just the exhaust cam that's different as on the LSJ both cams are the same length but on the "reg" Ecotec the exhaust cam is shorter.
On a supercharged engine you want a cam with lots of lift but with much less valve overlap than a "hot" naturally aspirated cam. I've been asking for COMPcams "boosted" ECOTEC cam specs but they have yet to reply.
I have a guy that will grind GM blanks for us to ANY spec we provide, but the GM blanks are expensive- $200 each!
im just going to have saturn do it when I get the Psi kit I will do it all at once in their bay. Tell me they void warrantys for aftermarket my ass. They help me do almost everything I put on these cars.
ahh son of a bitch upon closer inspection they are differnt lengths. This is not going to work is it. FUdge.
See on the LSJ you can use 2 regular "intake" blanks and have them custom ground
I've been messing around with various lifts and grinds in some cam software I have
But it might be better to copy a commercial cam (with a dyno chart) setup to make sure we get what we want. (Daily driver 400WHP @ 18psi boost and 25mpg)
Were these supposed to be a "supercharger" grind? It should have come with a spec sheet for degreeing it during installation, can you post the specs??
Hi guys! I registered here because I have an Ecotec and I'm thinking of getting a IRL down the road as I'm gonna need a 4 door, since I have a Grand AM coupe right now. I wanna get another Ecotec but as much as I love my Vortec SC, I want a factory SC Ecotec this time. Anyway, about camshafts....
I have camshafts in my Ecotec and I'll tell ya, do not get camshafts unless you are prepared to do some tuning. The cams cause the engine to lose vaccum, I have only 12in of vaccum at idle. Therefore the ECU reads that as load and dumps fuel and makes you run rich and also pulls timing.
Its killing my SC power so I'm taking them out Tuesday and going back to stock. I've had this verified by RSM and a friend of mine who is GM tech. He tried putting W41 cams in a regular QUAD HO and had the same problem, he took them out at ran better times.
25-30 horsepower with cams? I don't think so..not at the top end at least. It's the gaine throughout the torque curve that make people buy them. I think i'm right, am i? Thats what i've learned all my life.
anyone know the stock specs on the redline cams if so can someone tell me
the techs at crower cams said they can custom grind a cam to fit our applications but im sure your going to dip that wallet pretty good for a set
