RED = MAP ported exhaust manifold (SPC coated)
BLUE = MAP short-runner tubular exhaust manfiold (SPC coated)

Crazy you make that much power on 93, badass.

You think the short runner might perform better with a bigger turbo or more RPM?

Looks like the ported does perfect for everywhere on a street car.

Re: GheyrodX - bigger, fatter, gheyer!
 

Most likely. The only place the short-runner showed an advantage was in the upper RPM band. With these results, I'm going to stick with porting as my recommendation for stock and smaller stockframe turbos.

Re: GheyrodX - bigger, fatter, gheyer!
 

Looks like an intelligent decision.

Re: GheyrodX - bigger, fatter, gheyer!
 

I agree, thank you. I should have just done the MAP ported from the beginning...

BLUE = PPI "extreme" ported
RED = MAP short-runner
GREEN = MAP ported

Re: GheyrodX - bigger, fatter, gheyer!
 

Damn! That or you should have gone to a long-runner instead of the short-runner mani!

Re: GheyrodX - bigger, fatter, gheyer!
 

Ported stocker looks like a win to me. Not only dyno chart wise, but also keeps the setup simple / OEM under the hood which is always a plus in my book.

Re: GheyrodX - bigger, fatter, gheyer!
 

I agree completely; plus it's much better for heat management, less risk of cracking, etc.

Re: GheyrodX - bigger, fatter, gheyer!
 

I compared all of these manifolds, the short runner was huge gains over ported stocker at ~550whp, baseline was like 525, and with short runner it was 550ish.

I'd post it here but not the right thread.

I agree though, on a stock turbo car the ported manifold is king.

Re: GheyrodX - bigger, fatter, gheyer!
 

I agree, with an EF4 and big power I think the tubular will dominate. We know how they compare on the EF2 and EF4...wonder how they'd stack up with an EF3?

Re: GheyrodX - bigger, fatter, gheyer!
 

^Well my testing was on the FPblack, but I get what you are saying :)

I wouldn't ever run the short runner personally though, I like American welded things. But the design is solid.

Re: GheyrodX - bigger, fatter, gheyer!
 

My friend down here does has a MAP long-runner just sitting in his garage... ;)

Kidding kidding, I'm done testing out exhaust manifold setups, I've made enough changes to that! Now if MAP were to place a Rev2/3 ported intake manifold in my lap... :D

Re: GheyrodX - bigger, fatter, gheyer!
 

Mike Rizz, said that is one of his reasons from getting away from a tubular manifold, he had 1-2 of them and he said the engine bay heat was terrible and they would fade/ruin his clearcoat on his CF hood.

It's making me want to stay with the FP cast manifold I have.

Re: GheyrodX - bigger, fatter, gheyer!
 

Ceramic coat it and call it good...maybe do a little cleanup porting too?

Re: GheyrodX - bigger, fatter, gheyer!
 

The OEM manifolds ported work very well, they are a bit restrictive for sure, but spool up is always a good 400-500 rpms better with them and heat is managed better and you get to keep stock heatshields on the Evo X anyway.

Still made 570whp+ on the FPblack with one, it held it back for sure but was adequate.

Both have great benefits.

New Girodisc S/S (orange) brake pads on the way...I don't need them yet, but they offered me an introductory price that's too good to pass up.

Re: GheyrodX - bigger, fatter, gheyer!
 

Those sound awesome.

Re: GheyrodX - bigger, fatter, gheyer!
 

I hope so. I had terrible luck with their Magic pads (twice) so this is my final attempt at running this company's products. My current Stoptech pads are probably still good for at least another 10k miles so I'll probably swap these new ones in sometime next spring.

Re: GheyrodX - bigger, fatter, gheyer!
 

^Sweet I have about the same amount of miles left if not more on my car, but it's all good parts store stuff.

Re: GheyrodX - bigger, fatter, gheyer!
 

Hmmm...what is this?

A second compressor cover you say?

http://www.mitsustyle.com/photopost/...m/IMAG0024.jpg

Both covers have a 3" inlet for maximum airflow so that alone is a nice upgrade vs. the EF2, but we're also going to be testing standard vs. anti-surge to see how they compare. Stay tuned for data this weekend...
