Have you used one of the Mondello wet flow benches on an Evo head?

 

If those #s are proportional to what we found then your head is spectacular. What kind of flow bench and what does a stock head flow on there? My SF1020 reads pretty low compared to most benches I have compared (10-15 less than an SF600). We also flow @ 50 and convert back to 28. If I flow straight up at 28 it gives me even more. I'll have to go back and read through my notes to see if I saw that 265 straight at 28 or converted. A stock EVO head flows 208 here.

 

The flowbench used for working my head is a JKM unit (a smaller version of the models used at GM and Ford), which consistently reads within 5% of a SF1020 - much different than a SF600. Everything was done at 28". I'm trying to put my hands on the stock EVO head data, but it isn't here with the others. I'll post it, even if it means putting it back on the bench.

 

Wow,,, boost does make up for alot...
A stock TSX (k24 head) flows around 280cfm if I remember,, and a well ported head with some larger valves and decent seats go over 340cfm...

It makes me want to turbo a honda...

 

A 600 can give varying results...3% either way. You are talking up to 10cfm above or below run to run. I know a few guys that have both a 600 and 1020 and with jump back and forth depending on what they are trying to do. I don't know anything about the one you have.

 

I looked but the only stock headflow numbers I still have in my notes are the Cosworth ones and I dont trust them entirely. I can post them up if anyone wants a look though.

The HKS manifold as pictured above was used in a car with restrictors, made peak power at 6500rpm, and wasnt really entirely succesful in competition.

Sean Glazar (as I recall, I know it was one of the OG DSMers) used ITB's on his racecar and didnt really see more power. This setup from Kinsler could be different, since I havent tested it I wont rule it out.

RB26s are factory ITB/Turbo but they are dual MAF so it goes along way to help keep it streetable. That is the only factory Turbo ITB setup I can think of as well so its not entirely common. I would assume the Alpina B10 is as well (though not factory and I believe also MAF based) but I cant seem to find any data one way or the other.

 

Johnbradley, I believe the SR20 also came with ITB's on the little hatch GTI-R. My friend Bill uses a modified version of the setup on his 240 TA car.

You guys do see that they aren't an ITB right? I keep seeing people mention this, but the one I pictured is nothing more than an intake manifold that you can tailor to your car... the runner length, runner diameter, and plenum size. You tell them your setup, and they help you make more power.

 

This is very true. I had a GTI-R swap into a 200sx as my first project car. I totally forgot about that haha... I miss that car..

On a side note i think the big thing here is the manifold will be tailored to your specs which you dont see hardly ever when it comes to intake manifolds. A huge plus IMO!

Yeah we have switched subjects slightly. I am sure Kinsler can offer it as an ITB manifold if it was needed though....especially since you said they can

 

Apparently you were the only one paying attention

Just gorgeous, If there's a need for a EVO Guinea pig just let me know, I've got a 35R that would love to push some compressed air through that thing.

 

Looks really good. Anybody know if those stands on the plenum are just for show of the velocity stacks or could there be a option to expand the plenum to a larger volume which would be a great idea!

Chris

 

I would think they're just there to showcase the sexors underneath the plenum... Cool idea though to have an adjustable Plenum size with a spacer...
