Yow. That's gonna cost like a hundred bucks or something.

 

Wow, it looks like the dinner I had last night.

Can't wait to see the performance results.

 

Chad, could this plenum be used in a 996 C4S?

 

wow subscribe

 

is it really for sale???

 

The car is not for sale.

What will soon be made available is copy of our system which consists of:

1) Carbon fiber plenum as shown above.
2) Six 48 mm throttle bodies.
3) Linkage.
4) Two servo motors for drive by wire.
5) Single or dual injector manifolds.

 

I don't believe so, but nothing is impossible. The reasons are many.

First, the runners are deigned to fit our heads which are GT3 Cup heads ported to RSR valve specs. In other word those intake runners are very large. A turbo head could be used but these would require some major machine work on the intake ports. This is something that many tuners are doing with the present big output motors.

Second, I do not know the lay of the land on the top side of the 996 C4S. This plenum was designed to fit in the 996tt engine bay along with being compatible with all the other parts in this area. The linkage/servo motors were a major undertaking. They had to fit and be compatible with everything from alternator to smog parts being in the same area. Our linkage runs under the plenum. We first tried to go above, but there simply wasn't enough room.

 

Is there any info on the pricing yet? or what it would take to install this? Do we need a retune etc.

Thanks

 

Pricing info won't be assembled for about 30 days. Yes, it will take a tuning adjustment because to get the response and power available due to increase in available air flow, fuel will need to be added.

What will it take time wise to install? I can give you a good idea very soon.

 

Looking forward to the additional info. I did, however, followed the above link which had a number of pictures. I could not figure out which configuration was the one your design was targeting.

 

Go to Tuning and Modification forum for additional infor.

 

Beautiful stuff indeed.

 

Joe,

Neil Harvey was a part two Championship F1 Teams. The guy is off the charts. These plenums are almost perfectly balanced runner for runner, minimal negative spots and designed to obtain maximum flow. This in combination with the individual TB's and dual injectors should provide the response of a race tuned NA motor.

 

Absolutely stunning, any idea on prices? Is it engine out to fit? Again beutifal workmanship

 

No pricing from Neil at Performance Developments as of yet. He has a couple more weeks to tie up all the loose ends. If you want to contact neil with further questions he can re reached at neil@performancedevelopments.com

I am not sure what you are asking when you say. "is it engine out to fit?"
