Best intake plenum/TB combo?

[Pertums]

i'm using a 75mm accufab with a p&p plenum. works great and you can buy a stock plenum on ebay for like 20 bucks to work on.

looks pretty good too:

Remember it's not all about hp the feel comes from the +20 tq you gain with a 75mm TB/P... BBK

If thats not a joke we require a dyno sheet, before and after.

It's nice to know the work I did way back when is still helpful.

I tested all the products that were available at the time.

Would a P/P job just clean up the plenum, I don't think you would get that much more CFM out of it...or am I wrong?

Aren't the newer plenums bigger?

mines matched up to the outlet of a 75mm tb. if you looks at just the inside of all the plenums out today they are really all the same thing. depending on how much material you take out you can probably land anywhere between stock and tops with a p&p plenum. for me the 1-2hp/tq gain with some 150-200 piece that i didn't even like the look of seemed like a waste.

as far as bigger, most of the new plenums have basically a spacer built into it on the bottom. i used a spacer and then ported it to match perfectly.

the debate will go on forever with these things. for the 40-240 range a plenum costs i'd say get whatever you like the most.

That is about right for a plenum but not for a throttle body...
