I know all the different plenums sold and wonder which one works the best. Looking to try one that would inhance my combination and help prevent a lean out condition at the rear cylinders! Suggestions or comments! Thanks! Gene

Just my $.02 is that the powerplate, stock doghouse and jay jackson TB, will be good for anything up to and maybe beyond a TE62 turbo. Assuming that a good flowing IC is being used.

It would seem that the pte version does the best job...but it also seems that a power plate does even more for less money.

I'm runing a stock plenum, powerplate, and ported intake/heads. I'll probably go to a jay jackson TB eventually.

I seen alot of back and forth opinions(this and other site) regarding the powerplate but I have not seen anyone really say "yes I was able to increase boost by 2 lbs with no knock", etc. Of course it would vary based on car setup but still someone should have some hard data, not just "It seems to run better or spool slower. Would think it would help the cars more with bigger turbos and higher boost.
I don't know, guess it can't hurt to try for $60, can it?

I have installed them on two cars...no hard performance data but both were able to run 1-2# more without incurring knock.

A number of people have posted 1-2 tenths better performance after tuning. Some dyno data has been presented to show a bit more power and Nick Micale did back to backs at the Nats and showed about 2 tenths as I recall on the test car.

My question was intended to improve flow with a big turbo, TE70, massive ported iron heads and intake, 206/206 cam, PI Vigilanti 0 pump/ 6 pump, 3:42 rear end, ATR headers and 3" DP and exhaust, no cat, 28" tires! I know Race Jace runs GN1 alum heads, TE70 turbo, PTE Plenum with power plate. Gene
