if you don't know if cams will or will not hurt your engine you might be a *******

again go read about engines and modding it doesn't have to be about ecotecs all engines are the same in one big way

 

I was wondering because with the extended powerband that going stage cams give weather or not 60#s would flow enough fuel through to support revving to or past 7500. I'm under the impression that it wouldnt make a hugw difference provided its tuned well, but I wanted to double tap and make sure before I started getting parts together. Reasonable logic/question for someone with minimal experience.

And I'd just like to point out that if you don't have anything constructive to say, then get the **** out and quit running up your post count.

 

I have given you use full advice your to blind to see it

 

Dual pass or better yet single pass does slow the rate of temp increase. I don't know how you got the results you did unless it was plumbed wrong or had an air bubble trapped.

Testing has been done over and over.

 

No, I got your message loud and clear. Going on to call me a ******* for asking a reasonable question is a little excessive.

 

no they don't ive ran both of the all they do is decrease recovery time and not so much that its worth spending the money on. its just like you saying swapping the cores for a dual pass is worthless

 

good go get some books and read you will benefit from it

and its not excessive

 

Maybe not excessive, but unnecessary. I might be ignorant to the topic at hand, but it doesn't make me a *******.

 

So ALL the other tests showing it decreases iat rise, including mine, are wrong?

 

Do the dual pass. Sorry MR B I dont agree. I think it does help a bit and the quicker recovery is worth it for such an inexpensive mod. Also Option B is great.

 

The dual pass aids in recovery. Drops temps faster than stock setup.

It does not slow how fast the temps rise much though.

 

only thing that changed for me was recovery time and it was not worth the money spent the only thing that helped was capacity

 

How do you figure? On my single pass with a 2.5, my temps climbed like a stock setup on a stg2 pulley.

Yes it helps with recovery as well. But it also keeps them from climbing as fast. I thought this was general knowledge. Do you need logs for proof? I'm sure I can dig some up.

 

I didnt say it doesnt help with rise.... I said it doesnt reduce the rise by "much".

Yes, it is slower, and all around better. I run a full GMR dual pass and Opt. B setup.

The main purpose of the dual pass is better recovery, so when you are driving around the track at full swing the temps can be controlled better.

My IAT2's still peak at 135-140 at the top of 3rd with or without the dual pass, that did not change. Nor did the speed of the climb change much. Recovery is what I noticed the most. Much, much quicker drop.

 

Same here. I did a heat exchanger, dual pass and option b all at once. Once fully bled I personally saw no difference in peak IAT2. Climb rate didn't really change much either from what I noticed. Recoupe time was noticeably wayyy faster though.

 

As long as you're not doing pull after pull after pull after pull, you'd be golden then.
My lsj is my dd and I log a lot of highway miles so I'm looking at a fmhe just to help with recovery times. Dont want to run hot and stay hot

 

Single pass ftw then.

 

I already have my fmhe waiting to go on, not gonna blow more money if I don't have to
