to my disapointment, not alot were taken. I guess I can't blame anybody seeing as how we were all pretty content with just hangin out, drinkin beer, and swappin stories.

The WestFest might have some great pictures ( June 29 to July 1 ) but I myself can't make it due to work. For me it's not even really worth going to any show untill Chris West brings his car out for the first time with the new drivetrain. Essentially a V8, but WCF style!

Cool, a fiero meet where the average age isn't 50+.

Nice headers on the Aurora. I see that it is a 2000+ engine, what are you going to use to run it?

Did you make the headers for the 4.0? Looks like a cool project with the NSX transmission.

I'm not so sure I like the non-equal length 4-2-1 setup, I doubt it will do anything more than a basic shorty header. However it solves the space issue, and more flow can't hurt.

Steven, is this you on the left with the red "sash" thing around your back?

Looks like it flows 10x better than my non equal length, non smooth factory stamped manifolds. My manifolds are completely different front to back, probabaly flow way different from eachother.

I get so tired of hearing about "tuned" and "equal length" headers.... DUDE, THERES NO ROOM :la:

Besides, it's still a V8 setup that will get V8Archie all un-hinged and worked up, hehe

Hi V8Archie

Really? I beg to differ.

Shorty headers suck to begin with. Full length tuned to the motor headers are ideal but it would be guess work in a fiero.

You could get a set custom made but it would be $$ and would never fit.

Those headers are good for what they will be doing.

Completely agreed.

You guys are more than welcome to come on down to WCF and show Chris how you would do it. Be prepared for long, insightfull points of view from Chris that stem from 40 years of engineering.

I myself am trying to figure out what the point would be of tuned headers when the exhaust is just going to slam agains the turbine wheel anyways - but thats just me.

crzyone · Post by **crzyone** » Mon Jun 25, 2007 12:24 am

no idea it was turbocharged. Completely different story.

A.G. Bell, from Forced Induction Performance Tuning, says that optimal is a 16"-24" equal length header with a standard collector. He also said there is no real way to figure out which will work best, as there are just so many variables. For their racing team, they started out at 20", and then added and subtracted until the power curve suited what they wanted. It showed the dyno numbers, and there was no obvious correlation between short primaries and which side of the power curve it favored.

He said for most street cars, a 20" long primary would be as good as is plausible. For race cars, with the resources to do so, starting at 20 and then dyno tuning them shorter or longer is optimal.

I am using 20" primaries on my car.

partially my fault, I never mentioned that it will be turbo'ed . Not sure what type Chris will be using but when I held it it my hands it could swallow a T3 whole

Sure, thats cool if you have the time and money to do that - more power to them.

I'm kinda thrown off by "street cars" should have a specified length and what not. A Honda Accord and Pontiac GTO are street cars, but WAY different motors. Does this idea still apply?

I know it doesn't logically make sense, but that's what he said, so I'm running with it. The headers don't seem to play a part on changing the power curve too much from what I gathered, that was determined more from the engine itself, and the turbocharger to be used.

No, I wasn't at the BBQ except before everyone got there and after they all left (to pick up my car).

And my hair is at least twice as long as that little shrub.

Probably Delphi MEFI 4 as its not very expensive and is small and tunable. Still looking into other options though.

Did you make the headers for the 4.0? Looks like a cool project with the NSX transmission.

Steve and Chris made them.
There is no possible way that equal length headers are going to fit in that engine bay with that motor. Actually, the headers in the pics don't fit either. Steve and Chris were redoing them when I was there on Saturday. They hit the firewall in a few places... That motor is HUGE and there still needs to be room for the turbo and exhaust downpipe.. don't forget a muffler too.
They're designed so that two adjacent firing cylinders are never sending pulses down the same primary. If it doesn't make significantly more power than stock manifolds it will at least sound pretty bitchin

.
I can't remember what the turbo is but its a large twin-scroll piece.. looks about the size of a GT40 or something. It's not a Garret though.

I can relate.

There is no room in my engine bay, only way to fit a turbo that I coul see is to cut out the trunk, which I did anyways.

The turbo kit I got from PBJ puts the turbo right over the tranny. I think he kept the trunk. My N* has no trunk right now. There's room to build a shallow one.

The NSX tranny shift cables and clutch hydraulics are all underneath the trans, so the turbo will be over the trans by the decklid vent. Plenty of cooling airflow for it there. The trunk won't be touched

The turbo PJB tried to put on the N* is way too small. A proper size turbo, a GT42 or other large turbo would never fit in that location with an intercooler and plumbing.

He said his turbo spooled at idle, not good.
