Thread: Mike Kojima's Dog 1

This is so cool..

Thanks for your advice Mike,

Are those lengths based around using a lowport or highport head? I remember you doing some testing on a lowport.

I am using the highport head which has the longer intake port and with the manifold im using has a total length around 12" from valve head to plenum.
The addition of a thermoblock inlet spacer would bring this upto around 12.5" and near optimum for my application, if not maybe still an inch short.

Any longer than this, and i'll have clearance issues with the firewall..unless the runners are curved upwards/downwards.

I am however satisfied with how the engine is running since installing this manifold and tweaking the cam timing, but i'll have to see what the dyno results say.

SR20-AUTECH

It was with a length of about 10" and 12" to the center of the valve with a low port. If you get good results please let us know. I have a short runner VE manifold I have yet to test.

choaderboy2: What you think about stock (or light port and polished) VE manifold on DE (Roller Rocker, Lowport or Highport)?

I think the ports don't line up since the VE's are higher. The VE is like a Honda engine, no torque and in a heavy Sentra it is sorta lame. Honda's weigh about 3-400 lbs less in race trim.

On this manifold comment, is this geared more towards DE or VE expreiments? I'm going 92x86 on a VE and I'm thinking a better manifold would help in my case, but for what you use ur car for, not so much.

An apples to apples comparison to th BTCC engine isn't possible IMO. To be in the game in that Series would have required 300HP at the flywheel. I think we have all seen the pictures with the custom header and individual runner intake, plus built on the different block, not sure about bore and stroke.

Awesome racing action by the way. I hated seeing that 1st lap deal and was impressed at the recovery. That is one of those corners where it seems very wide until everyone gets there at the same time, then you just run out of room.

I try telling people the DE has such a broad powerband (with the right cam and exhaust manifold combo seems to be key) and I get annoyed trying to convince people so.

Thank you for posting in here, Mike. It;s been a while seeing you on here.

Good to see you back on track Mike

yaya, stick with your de. lol.

mike its good to see you posting here more often.

enjoyed watching the race, motoiq is becoming a site i frequent, keep up the good work.

stratton.
