I'm about to pull the trigger on a sc here shortly, but my 08 base mn6 car has a cam designed for na application. My concern is what are or would be the effects with boost. I have an ls7 cam on hand as well that seems more sc friendly. I plan to run the stock boost for now.

Current cam specs are 230/240 609/588 114+3. My car has been as fast as 11.32@123 in the 1/4 mile. What should I expect as far as hp? My car also has full exhaust and ported tb. I have a 25% ud pulley that I know that needs to come off.

Any ideas? Suggestions?
Thanks

I would leave it in. It's not that far off from an aggressive blower grind. Lift isn't too crazy either.

Quick tip on a new crank pulley. ATI has an Ebay store where they sell "blemish" pulleys. I got my 7.5" ATI crank pulley for less than half of retail. It has a scratch on the back side of the pulley that you can't even see.

I know the cam isn't that aggressive, but I'm just not sure about behavior with a blower.

Im going to check out that store. Thanks!

is it an ideal cam no. but it will work just fine Your still on the stock motor so it will still take boost great even with that cam with no issues.

I know tht ECS kit is calling your name

It really isnt too far off at all. Keep it

Mike, I guess you replied to my work email. It's 5:40am here and I will be in later. So I am 8hrs ahead. If I need to call you I'll do it.

Thank you for the reassurance! Any ideas on how much power the FI would put me at?

jon6.0

If you wanted to put it on kill and you went with an ECS1500 setup with no inlet restrictor plate you would be around 750rwhp with methanol injection and pump gas.

With the inlet restrictor probably around 625-650rwhp and about the same torque.

Sweet! Well I just ordered the ECS kit!! I'm going to take it easy for now. I'm not in a hurry to make a lot of power that can become potentially useless. As it is these vettes are no joke with a few bolt ons, so I can't imagine what they're capable of at 600rwhp!

I'm currently deployed, so I won't be able to install and tune for now until I get back. I'm sure the wait would be well worth it. Thanks for your input!

Mike Im just being a right now.

Not a problem! I've heard your name for a while before you became a vendor. So I feel that I needed to give you my business to help you in your endeavor. It was nice to talk to you.

Thanks!

Can i piggy back on this thread? I have a 222/228 x 114 +4 (.578/.561) cam on an otherwise stock LS2 with long tube headers. I am contemplating going with an eforce. I was thinking about going back to the stock cam. Other than adding more power how does the supercharger effect the cam? Does it even out lope?

jon6.0

That cam will be fine with a blower. It may smooth it out some in the lower RPM's while driving. It will lope the same as it does now. If you don't want the lope your tuner can raise the idle a touch and smooth it out.

mfoti

Thanks! that helps. Do you know if the Eforce tune will work with a cam? I guess what i am asking is.... how good is the included tune? is it for a "stock" car? Is a dyno tune a must after adding the eforce with a cam?

jon6.0

The canned tune is for a stock engine. I would just get the Edelbrock tuner kit that doesn't come with the canned tune and have your choice of tuner tune the car.

Pitufina

Those tunes that come with kits are usually for a stock engine. They tend to be on the very safe side. Meaning running somewhat with an a/f ratio that is richer that what a tuner would use and possibly even low timing as well.
That doesn't mean that is going to run great with the cam either. Personally I would start the engine with the included tune, stay off boost and take it for a real tune. Not only would it help power wise, but drivability too.

Hope that helps.

Pitufina

Or you can do what jon6.0 suggested.

great thank you
