I am looking for all information on the Power Intake Plenum for our cars. I see they say 30hp but I assume thats just what the turbo will get.

Who has one?

How do you like it?

Install?

Pics Pics Pics in the engine?

Pics Pics Pics of the Plenum itself (inside and out) and what makes it so special?

Places to pick one up?

THANKS!!!!!

 

on the 3.4 you get that power. not on the turbo.

 

ok well good, then for my N/A what do you got?

 

Havent officially dynoed my car, but according to my butt dyno, the power is much smoother in delivery. Its not like your going to get pushed back into your seat power, but its noticeable change.

 

ok so is this the one. This is the first pics i have seen installed









So looks to be the big difference is that thing in the middle that redirects the air
flow better to the sides?

 

Where did you get the plenum? Curious as to cost v. horsepower (or perceived hp)...

Got it on a group buy ~800. Performance ~25hp dyno'ed by some folks here on 6 speed.

Perceived, much better throttle respnse and the power curve feels more flat. Pulls even at 90.

I like it and it was worth it to me.

Im talking to a local shop to see if they can make one of these or not. A friends place and he says the cost of materials is so small he doesnt know where the extra price comes in...... i said its because its for a Porsche haha

 

are there any problems with the engine running lean, or not passing emmissions?

 

You paid $800 for yours? Was is the group buy the ended on 8/31/07? I paid $875 for mine.

 

my car runs lean. Pulls even on 6th gear at 90 + a have a bigger throttle body

 

I dyno'd my car. It made power. Do a search for my thread. I posted the dyno charts if I remember right. The product works.

 

No problem passing emissions, just had mine done. Passed with flying colors.

I saw somewhere on here, that you need shorter bolts to install the plenum? If that's true, do they come with them?
