Are the 2-3 runners equal length on that exhaust manifold?

 

2 of the runners are long and each go to one side and two are short. Its well designed. Here are the Dyno charts.



As you can see the Stock turbo just runs outa juice. The over all mid range gain is nice considering once again... its a stock turbo.

 

Impressive gains IMO! That's a nice midrange kick.

 

That manifold is really going to pay dividends once you start revving higher with cams/springs, especially if it's with a larger turbo.

 

It's unusual map would go to the trouble to make a tubular manifold and not make the runners equal length. Usually if you Cant make them equal you Should make them as short as possible, like a cast manifold.

Good news is the stock manifold flows very poorly, so you've taken it out of thr equation now

Do you have the boost Logs from the runs? I don't think you should be maxing the turbo out at only 314whp.

 

 

wow, there is some power left on the table there. boost is falling off really bad. let me know if you want to fix it

 

Mmmm i bet your licking your porkchops on that one

 

Please post some dyno charts on some EVO X you have done with stock turbo.

 

Are you running a 3 port bcs, mbc, or stock bcs?

 

3 Port

 

Why did you go back to pump? Also, can you update with all of your current mods?

 

Im back on 93 octane because Im going larger turbo and cams. Im sure I will go e85 again at some point.. However not for now.

I literally got 98 miles to a tank of e85 a few weeks ago. I love the e85 feel, power and not blowing huge smoke clouds on my fellow motorist... but I also like getting MPG not GPM

i wonder if you just use stock ported MAP manifold exhaust and intake. maybe higher gains
