Plenum Most Capable Of High Hp

[Tocchi]

hey guys, looking at purchasing a plenum asap.

currently ive got the stock F6 bbm (so no butterflys)

this needs to go

basically, got a Phoon motor going into a capri drag car with an ETM kit that has a rather large turbo

looking for 800rwhp

im just wondering what the best plenum is out there for high HP applications -- if there's a conflict on this issue because of site sponsors, please PM about the plenum I should choose

ive been looking at:

Process West

Plazaman

Nizpro (carbon fibre plenum)

so yeh, basically, need something that wont be too laggy. running a big turbo gives me enough lag.

Maybe a nitto or get someone to build a custom unit. I have a process West plennum I dont know what its max HP would be, I am running 500rwhp.

There is only a small handful of people on this forum that have gone to that sort of level!

In a capri that thing will hammer down the quarter! What time do you hope for?

ive seen the Nitto ones.. they are a compete upper and lower plenum if I remember right??

it has run 8s with a Clevo 383 pumping out 650rwhp

but im "new" to racing, so I wont be seeing those times for a good half a year at least.. need experience.

but once I get speed, the 800rwhp should see me in the 7s

nitto plenum is complete replacement including the runners

Any of the plenums you have mentioned would be good for response, but the little used Nitto plenum would mor than likely have a larger capacity for air

I would go the nitto plenum, in this application. would be the biggest hp gain - most direct air path.

Without sounding like a Nizpro stooge here but the only plenum on the market that is PROVEN to flow 1000hp which is close to your 800rwhp is the Nizpro plenum. I'm not saying that it is the best one for your application, I honestly would imagine that a custom job fit for EXACTLY your application would be best but outside of that if you aren't interested in doing the R&D involved and only looking for 'an off the shelf item' then I would think that the Nizpro plenum would be your best bet.

I would think (actually hope) that all of the plenum's on the market are derived specifically for a street or actual use application. This is a scenario that you aren't after as it is a drag car first and foremost. So low down response, fuel economy etc wouldn't come in to it...

Ive run 650rwhp out of the Process West plenum on mine and will be running around 800hp very soon. I dont expect to be changing the plenum so I have no doubt it will manage the power without problems. This was on a T51R running about 25-27 PSI. The rev limit of the engine (about 6200rpm) was the limiting factor. This should be fixed shortly as well

The older Nizpro version has been publicly demonstrated with over 1000HP on the engine dyno, and run to around 1250HP, done about 3 years ago.

New carbon fibre Nizpro version (not yet available) that includes lower runners should have better low down response, but not sure about top end. I will test a new version soon.

Nitto is laggier down low, but looks like it could have very good top end capability.

Plazmaman looks to be slightly larger in volume than Nizpro. YLD-11Z (with his ETM manifold and GT45R turbo) is running a Plazmanan plenum and wants to push around 800rwhp (600rwkw). You could try pm'ing him about his current test results.

Process West looks to be around the same size as Nizpro. You could pm Process West (Kevin) regarding any big hp cars using his plenum, and there are quite a few guys running his plenum with 350-400rwkw.

RDP were running 800RWHP through the process west plenum.
