The pictures are deceiving because of the angle they were taken at. There is actually 4" between the closest runner and the fuse box. I think if it were going to melt it would have happened on the dyno where there is no air flow going through the engine bay.

Of course i experience some vibration with solid motor mounts, and a fully gutted car your going to have that. Other than 2100rpms (where my mirror wants to jump off my windshield) it's a non issue it doesn't bother me at all.

If some one wanted to buy that setup it would cost a ton of money. I have no plans on producing a second one however if someone seriously wanted to buy one I would. To give you an idea of what i would have to charge that manifold cost me around $2200 in materials (including cutting the flange) and the wastegate tubes.

The intake manifold was significantly cheaper I think i payed around $600 or so in materials, plus a throttle body.

 

Quick random question...

How did you get the throttle cable to work with the relocated throttle body? That cable is a specific length, with minimal play for adjusting for when it slacks out with age.

actually the cable has about 3 feet of extra slack where it wraps around in a circle for absolutely no reason... I always though that was a bit weird but turned out to be useful. It's still to long but at least it's not quite as ridiculous looking.

 

wait, you said the exhaust manifold cost you 2200?

 

dear god!!!

 

yeah those burns collectors are about $700, the flange was about $300 (321 1/2" thick cut on a waterjet), 2 flanges for the wastegates were about $40 the wastegates took 4 u-bends to make $160, 4 u-bends for the header $480, and about 6 90* bends $420... so maybe $2100 mostly because its 321 tubing instead of the 304 pipe most people make manifolds out of. I built it myself so there was no labor cost. Obviously if i made a bunch i probably wouldn't waste as much material and would be able to buy in bulk but no one would buy them. Its worth it to know its not going to crack though and its actually equal length, you would be surprised how many "equal length" manifolds are not even close to equal length.

 

321 is some expensive/strong stuff... a bit overkill for most applications, not so much for a Time Attack car... the stronger the better on that application.

My header uses ACMS (Aluminum Coated Mild Steel), and was then ceramic coated for corrosion resistance/heat mitigation. Apparently Mild Steel is less apt to crack compared to 304 stainless, but tends to corrode... hence the coatings.

it's way overkill for most applications, being that it has a slip collector its probably even overkill for time attack but i would rather build the first one right and know im not going to have to build another.... if you want expensive though check out some inconel prices.
