the hot jetcoat is supposed to work simple physics the hotter the gases the faster they travel if you cool them down they will slow down, jetcoat helps the hot exhoust gases to be containned inside the manifold and not radiate, however does the car actually see the difference i think they are to minor to be noticed.

did i pick up any power with the ported exhaust manifold i dont know i did my hot side and exh mani in one package, i dont know if it hurted the car or it helpped it because i did not do a back to back test.
my take i think it helpped maybe not

i am sure Bushcur has tested this long time ago i am just not sure

 

Whats the turn around time if I were to send you my manifold for porting as well as the jet coating? Looks great!

 

+1 on turn around time.

 

I had one Ported by Buschur and sold it so I can now do another one ported and coated this time

 

heres mine very happy

 

Thanks Jarrod, I appreciate it! I will be in touch for sure.

To be honest the buschur is just a basic port with coating to make everything nicer looking. As I said before coating cast iron is only for looks since it holds in heat perfectly fine. Can you get a better ported manfiold? Yes, but it will cost a little more.

 

Lots of proven results here, and the cost is unbeatable. I have the whole package except for an older O2 (ported/coated hotside, ported/coated mani, SS O2), and you see in my sig what I ran on the stock turbo at extreme altitude (subtract 3-4 tenths for sea level if you wish). I now have added the Buschur ported intake manifold, Buschur 3.5mm TB, and a Green. I've lost some spool as expected, but it pulls like a freight train far into the nether regions of my tach. That is of GREAT SIGNIFICANCE due to my mile-high altitude where turbos lose efficiency, especially stock-style ones. My stock turbo would peak at 5300rpm and drop ~60whp by 7000rpm. Now, the Green spools later, but already matches the stock turbo peak by 5300, continues to climb, and then levels off instead of dropping like a rock. I hope to show these improvements at opening day this weekend...

 

buschur all the way!

 

+1 Just need to finish the tune and waiting for my new turbo to go on it.

 

the megan manifold is a POS. It Will crack

 

Jrod how long dose it take to port the intake manifold with the TB, and also do the build head??

Planning on getting this for my next build

 

^ +1

 

anyone have a diy on exhaust manifold, searched and only found one for the o2 housing

 

When will buschur start doing this for the EVO X stock manifold?
