Turbo Camshaft ; Grind / No Grind ?

If you call Delta and tell them your specs, and what you are expecting to get from the cam, they will cut it however you want.
Those guys are awsome at Delta.

just referring to dyno! :)

we should look into a custom boost grind, chris... im thinking maybe 242 or 252 but an assload of lift?

maybe i will call them up sometime next week and pick their brains.... delta cam is so cheap i would be willing to try a couple different grinds (of course this doesnt matter until i get my turbo system installed)...

ps im considering AEM EMS... :( MS is seeming kind of ghetto, and i like the features of EMS. but not the price tag.... maybe ill roll SDS EFI like jason! heheh

call up Colt them are suppose to have the specs on a turbo grind for us, and or talk to delta and talk about your set up. Idealy a 272 would be the most duration you want for a turbo. The idea with a turbo is to have as little valve overlap ass possible, so less duration and more lift.

from all the stuff ive been reading lately, maybe a 262-272 might work good also? Ive been seeing some high revving boosted b series guys make power with like Jun/skunk 2 stage 3 cams, more so than the specified turbo grinds by the same companies... so maybe im a little too conservative on cam size?

is the specs from colt cams.. and I thought I did mention it to you awhile back...

Does "Advanced for turbo 2" mean they are cutting the exhaust lobe further from the intake lobe (Increased LCA "Lobe Center Angle"), making the exhaust open and close earlier, at the same time decreasing overlap that would normally be there with the regular Stage 2 N/A Triflow grind?

im trying a gude cam for boost. Ill let you guys know. I think its a 252 grind with big lift

hopefully ill get to try my delta 272 for boost. ill also try stock and tell you guys what the butt dyno tells me :D

this prolly wont be any time soon though *sigh*

the butt dyno is gonna be very misleading comparing cams on boost

Lets say I were to get the tri-flow from colt, then later I add a turbo. would that grind be compatible or would I need a specific turbo regrind.
I want to increase hp but don't have enough yet to get Sean's turbo kit. So I was going to get the cam regrind to make due for now. another concern is that I probably won't gain much benifit from the cam without headers so that would also need upgraded. But then when I go turbo, the header(and maybe cam) will be useless.....
What are some thoughts??? Should I just go the N/A route for now or save up for the turbo. In either case, I will be getting the gm ECu upgrade with DIS. But if the cam will give me noticable power with out header upgrade and if it is compatible with turbo, I will just get the cam for now then add turbo when i have the money..
any insight into this matter would be great.
Peace...

hey what you want is the valve open right when the piston starts going down, and close just before it come up, but i cant find my manifold, do you know a company who can do it and ship it to me?:violin: i got a big turbo off a volvo and i want a manifold to use it with:rockon: i figure with the displacement theary, it should blow the crank right out .:rockon:
