I wonder if thats why the engineers didn't design the car with a ported manifold, cause of the whistle. Odd.

[simulatedwood]

Thanks. Unfortunately, the ported intake manifold will be coming off. Since the install I've heard a faint whistle on moderate acceleration. I initially thought it may be a slight leak, but I've heard from others that they experience the same thing after installing a ported intake manifold. It would be nice if things like this were disclosed beforehand rather than people not mentioning it until others have trouble. Luckily, I should be able to do the swap myself this time around in under 2 hours. Sticking with my goals: No compromises.

This made me think of whistle tips, that could get annoying fast.

This is the first time I've ever experienced any type of noise from a ported intake manifold, but it's also the first time I've done a N/A car or a plastic manifold. A few guys have some theories as to why the manifold does it, but I'm not going to dink around with it; I plan to just reinstall the stock manifold and not worry about it. I think I know what aspect of his porting it is causing it too but don't want to risk it by having anything done to my stock core.

About 30 miles on it so far...and yes, I'm ready to be rid of it :lol: The first time I accelerated I was like WTF?!?!

You should throw it on the dyno before you switch back, just to see if the gains are even more than a couple hp.

[Spoolin_Turbo]

^ second that

[Kracka]

You guys are killing me...I'm trying to fight the temptation to keep it, not tempt myself further :D

[A//// Guy]

Haha regardless you can always switch out, but might as well test and compare things since you are doing that with all the other mods? Or did you not dyno after exhaust and whatever else.

[Kracka]

I've only done direct back-to-back dyno testing on the ported/coated exhaust manifolds since that was part of my deal with MAP. Otherwise, I have a stock baseline dyno run @ Cobb and that's it.

Well then it's about time to get more numbers :)
