LET ME GET SOME FEED BACK OF WHAT YOU THINK
 
I think I would remove the insulation , reroute the wire harness and VAC line before it go's POOF into flames.
 
Those are some LONG runners on the headers....looks good though. You gonna be able to close the hood?:poke:

Joe
 
ya i have some more stuff to reroute, but the hood does close. i still need to heat coat the header and wrap it. the header has long tubes for the floe of the exhaust. the head has been ported to hell and back so its flows better with the header.
 
How big are the header tubes ? They look kinda way too freakin big. LOL
 
Be pretty good on a 6000+ rpm engine. Lots of volume to fill and surface to loose heat energy.
 
The intake looks okay but the exhaust is crazy. From other header results on here, big tubes like that loose power. ATS or PDI t4 is the way to go. Easy, 10x cleaner, and doesnt loose power. Props on building your own stuff though. Tim
 
i think your giving the intake a run around too cuz you went fron the front tube of the intake to the rear of the head and vise versa. unless you want equal length intake too? other than that the fab work looks very good.

Joe
 
You appear to have some pretty good fab skills, but the design is very lacking IMO. This is not an attempt to insult you or your abilities. Heck I can barely even weld. I will give credit to anyone fabbing up their own parts and trying new things. However I feel that you will be disappointed with the performance of the exhaust manifold. I think the intake manifold will work alright, although Im not real keen on the design. Also I am not sure if thats the best way to have your water injection system hooked up with 3 ports feeding off of 1 line, especially if its only a snow kit.
 
It looks like the header may be made out of stainless weld els? If so did you backpurge it when you welded it? Every stainless manifold I know of around here has cracked if it wasn't backpurged...

I'm not too wild about the intake design either, but it would be interesting to see some dyno numbers before and after to see if it helps at all.
 
I love the intake! I am curious how the exhaust will work, Killer fab skills! Keep up the innovative thinking.
 
the question i have is whats the reason behind the intake runners crossing i think it would have been just as efective to run the left side to the front and right to the back and take less room up and would be fairly the same length good to see someone trying new things and good fab work not sure how the header will turn out for you far as spooling but should be good on the topend
 
looks good man. way to think out side of the box, don't let those who can't get you down ,keep up the good work, it's always better to build than buy.
 
what size primaries are those 1 7/8? 2"? it's gonna be a dog down low for sure, but it'll be interesting to see how it does up top and what the EGT's look like assuming you can get on the turbo
 
i will let every one know how it all works at my shops DYNO event is tomorrow. i will have it all to gether so i can make a few pulls. some questions answered, the intake is like that to clear the stock fuel lines and the fire wall. the header i dont know what the theory was. i will see if it can spool a BIG A TURBO on the street and if it works i will be happy, if not i will just start from square one. thanks for the input
