I have picked up both of these items and plan on using them with my B16 head. My question is do I put the Spoon plate closest to the head or the Hondata gasket or does it not matter.

Im assuming it will effect power at a certain rpm differently each way im thinking ill get more mid-range power the closer it is to the head but I wanted to get a expert opinion

Thanx in advance

 

the spoon plate is junk and will cost you hp, throw it in the trash. problem solved

 

Beat me to it.

 

The Spoon rubber chicken!

Seriously though, does anyone have a dyno chart of one of these things in action?

 

Any ideas as to why Spoon would make something that costs HP?

It has absolutely no benefit?

 

plenty of reasons why...

throw it in the trash, lol

 

Well thanx for the heads up,

I got a spoon ventuli plate for sale...lol

 

it is used kind of like a restrictor plate for engines running in classes with hp limitation, it sacrifices high rpm power for low end torque and midrange.
I might be wrong though!

 

I always thought it was a way to narrow the intake port to increase velocity. If it worked it would be a great idea but I have never seen a dyno chart to prove if it did or not.

However, at $250 or whatever it cost I'm sure the HP:dollar ratio is all out of whack!

 

That's what I was thinking, ill just sell it and get my IM port matched,
I only bought the plate for a buck so it'll be easy to re-sell

 

When I changed my b16a2 head for a p+p ITR head last wkend, I found one of these venturi plates fitted to my engine (jdm delsol sir). It had no other gasket, just this plate fitted.

I have no dyno numbers but the car pulled ok for a b16, full weight delsol, non transtop, all stock apart from 4-2-1 ebay style header and intake, OEM exhaust, no cat, ran 15.1 with 2.3 60ft on nasty JDM tyres....

Not worth the cash obviously tho...
