Its not painted... But I understand what you are saying its ceramic coated and it looks hott! But teach each his own like you said...

 

The goals are quite simple. Accept whatever it will deliver around 35psi on E85 (fuel system permitting) while maximizing transient response and spool characteristics, and care for it such that it lasts a long time.

It's easy to make power
It's easy to have quick spool
It's easy to make it last

The real challenge lies in getting all three at the same time.

 

looks slow...

 

that is so true. i used to do 1 mile shootouts. i've had motors last thousands of miles and some would let go during test runs before the event . now a days, i would rather have it last, make power and lastly, spool. in that order.

 

And not many people can do all 3.

Exactly, which is why I reasoned that if I can get 600+whp from this twinscroll setup that already delivers 20psi (1.4 bar) by 4000rpm in a 2.0L, while having enough airflow capacity to get a broad powerband inside a moderate rpm range, I'll take that all day long.

 

Sweet set-up Ted, looking forward to your results and as always enjoy your transparent information on your projects. I seem to remember you thinking the heat treatment was Ted. I hope it performs up to your expectations and doesn't flake or deteriorate. Any chance it the HPC coating? Merry Christmas.

 

I am not convinced these paint-like coatings work nearly as well as advertised, but if it works half as well and does not flake, it is better than nothing. I prefer the Swaintech product, but I don't trust it being exposed to direct moisture.

 

why not go with a wrap?


i had my subaru up-pipe swain coated and it only lasted 6-8 months before it started chipping

 

Keeps heat in the metal, not just solely in the Exhaust gasses. Does a better job of keeping the manifold hot than anything...

still works, and a properly designed and built manifold should take it no problem


but really we are talking about tenths of a percent in performance increase

 

Depends on your goal.

No manifold is built with exhaust wrapping in mind, the fact that all manifolds don't break from using wrap isn't from the fact that it isn't causing fatigue but that some manifolds can take the extra heat.

I guarantee you GOOD thermal coatings (swain is one of them)have much more than the tiny benefits you mention.

For thermal coatings to keep heat in, like manifolds, I wouldn't be surprised if the main gain comes from reduced water and intake air temps just from the drop in underhood tempreatures, the gains from keeping heat out like what they use for coating pistons and such can drop temps dramatically, which help lots of things...

Great looking engine bay, Ted. Can't wait to see what she does when everything is complete.

 

Update?

 

Between the holidays, rain, and a faulty starter solenoid that we had to replace, I haven't had time to do much. As soon as I can pick up again with the tuning, I will provide updates.
