Plazmaman Plenem Vs Greddy

[9krpm]

Has anyone got any comparison data for Plazmaman and Nismo plenum?

The Nismo plenum is designed for mid range response and would be a better comparison.

I doubt you'd be able to do so to a point where air in the intake is anything but turbulent, mate.

But wouldnt there be a pressure drop in there arising from something not really worthwhile chasing?????

has anyone managed to fit in a strut brace over a 25/30 in a r33 engine bay without having to lower the cross member? (i know it would depend on the brace)

yea mine with the Greddy intake.

[juggernaut1]

Yes, with a long slot in between the first and second plenums (and longer runners).

Here's a closer design:

In this design, the vertical slats help to smooth and direct the flow of air.

Here's a couple of pics for a sr20 using the above "dual plenum" concept.

wonder how im going to get my q45 throttle body onto my plazmaman plen. gonna be a nasty cut n shut job LOLL.

[rad100]

hey all,

so i have read this whole thread.. great info..

i see so much love for the plazmaman.. but still undecided on if i should go for this or the greddy..

how do they both compare with stock throttle body? will a plazmaman fit on a rb25 in a r32?

i want to make my car responsive (grip, drift, hill climbs)

i have herd the plazmaman are a pain in the ass to do work on the intake side of the car..

any tips/info would be good.. thanks!

Do you have any pics of the 40mm phenolic spacer?

Cheers

Here are some of Noel's:

God those throttles are gorgeous, gotta get around to getting one, would finish mine off nicely me thinks. I see that they have slighlty changed the plenum with "Plazmaman" not being engraved on the top but now on the bottom.

I like the alloy boxes you have made Im doing some like that soon

Here are some of Noel's:

i spy a 30, they must be fairly recent pics?

[rad100]

can u still work on and remove injectors easy with a plazmaman?

and is it worth biting the bullet and getting a 80mm throttle body straight up?

yeah thats just after it went in end of march i think

[FineLine]

Thanks Daniel. the spacer can clearly be seen in the 2nd pic.

It not only lengthens the runners but even at track working the engine hard I can put my hand on the plenum. Whatever its made of it is brilliant insulation material.

MY EYES!!!!!!!

Chrome overload.

Got myself a p/m stealth series plenum. Love it.

[FineLine]

MY EYES!!!!!!!

Chrome overload.

Not yet! Theres still a few bits I want done.

Not yet! Theres still a few bits I want done.

the only things left that haven't been are the speedflow fittings and the fuel rail.

Cheers man. Turned out pretty good for a first effort. They are quite good at concealing a bunch of things

[PM-R33]

Yeah the injectors aren't a problem. Honestly I don't find it a problem to work on anything with the plenum. The only thing which is a bit annoying is doing the oil filter but you get used to it or just buy a relocation kit. However mine is probably a bit more annoying than most because I have briaded fuel lines everywhere and the taking the filter out snags on them all and they aren't easy to move around like the factory rubber ones.

I am also wondering about an answer for these questions?

Anyone?

Cheers.

[RBceffy25]

and is it worth biting the bullet and getting a 80mm throttle body straight up?

And this?

I will be using a Q45 throttle and I am wondering, what are the merits in this?

I was going to buy a P/M plenum but then i came across this puppy on ebay for pretty cheap which originaly had a 90mm GM throttle but i pissed it of in favour of a newer and in better condion Q45 model.

[RBceffy25]

whoops.

and the rest.

[PM-R33]

No offence but that looks hideous and it's ability to flow well would be questionable.
