Does anyone know if this makes midrange power at the sacrifice of high end? Or is it a win/win situation?

If the information provided here is correct, it looks like it may not be a bad investment.

 

i hear it doesn't help really...

 

Spoon's actual application for the ventulli plate was just for the B16A. Of course it will fit on Type R's too but that's not what it was designed for. I would think our rod/stroke ratio is too low to take advantage of this and would be a restriction as our engines require faster intake entrance speeds. For a B16A I could see it helping as it doesn't need to move air as quickly with it's slower piston speeds and longer dwell times so it may give it some of the midrange it's missing.

 

these are made for b16a plain and simple ...

 

Another thing we don't need to waste money on.

 

Ventuli plate narrows down the inatake port of the B16A and B18C engines to offer more mid-range power. we tried and test on the ITR the low end was improved and a bit more mid-range but no gains at the top.

 

So are you saying that there was no topend loss?

What were the gains in the low and mid?

 

Any numbers?

he sells them. why would he say they lost power? that's just bad business practice.

 

Granted.

and I'm still waiting

it restricts flow simply because it's there (versus not being there).

unless the ventuli velocity can offset this...I don't see high-end power

but numbers are numbers...

 

I am just interested in numbers. A graph would be nice too!!!!

 

I tried but it was a long time ago so I think I lost that plot already. 1000-6000 +3whp but after that is the same.
