What is in the works. Below is a couple pics of our World Cup Challenge plenum. We will cut the lower legs to to required length to match the 50 mm barrels. Further research indicates by use of the 50 mm barrels we can pickup 75 hp along with alot or response time on our engine build.

The parts are just over 8K. The labor will be about 6K and that will probably end up being a very good deal. That does not include the cost of the World Cup Plenum.

This is a three index oil pump. The gears are being prepared for friction coating. These pumps today cost about 12K. They suck the oil off three different areas of the motor virtually leaving no loose oil anywhere.

Suspension is a long story and as radical as the motor. The front hubs and cross member was designed by Cary @ ERS, Currently about a 20K system for parts only. The coils are JRZ four ways, everything is mono balled and control arms and camber plates are GT2 or RSR. The brakes are Brembo full floaters, Leman Callipers, 380 mm fronts 350 mm rears. Lexon tranny mounts and motor mounts. The tranny is fully built, changed all six gears/shafts, steel syncros and tranny cooler. It also has a billet RSR LSD It has been so long that I can't remember it all anymore..... sorry If you find a April 2004 issue of Excellence it pretty much describes how it is set up. The article is called "Clear for Takeoff." The author Dave Colman took it out and his first run was Top Time of the Day with no one else even close the rest of the day. One other thing, the car is very light.
I took sharkster from sharkworks for a ride on the Mt Hamilton twisties a few years ago. Ask him what he thinks about how she handles. He will probably tell you a story about dodging a bird in flight. The story is true.

Either way after that drive I've been using double and triple adjustable JRZ/Moton combos ever since heh... Not to mention all of this stuff too: http://www.sharkwerks.com/products.p...ype=Suspension
Even my daily driver 2009 997S has all the arms/links and solid stuff
Your car was quite ahead of its time eh?! I wonder if that bird is still alive
It had a death wish and it's lucky that the car in questions was yours. Try doing that in a normal car eh
?

LOL that was fun... I think it's actually partly you're fault I'm in this industry now Either way after that drive I've been using double and triple adjustable JRZ/Moton combos ever since heh... Not to mention all of this stuff too:

How many people from 2000/2001 are stll around these boards? Remember when 500 hp for a 996tt was the Holy Grail? Porsche with it's GT1 won Le Mans with a 600 hp motor!

I'd like a GT1 with a KA engine in it

During discovery I learned the barrel has no obstruction "a la buttery fly and shaft" as the RSR type does. The RSR type was designed for a NA motor. By design given the same size throat ...... the RSR flows less air than the barrel type because of the shaft and butterfly. The RSR type has a history of having a weak shaft. If the shaft breaks it can be catastrophic to the motor. A fix is to have new shafts made of 300N material which will add an additional cost of $1,200.00 just for machining the shafts.
The RSR type is designed for a NA motor. Under boost one bank could become stuck which would result in another problem. This has been an issue where the RSR type has been adapted to turbo use.
The above being said, I would like to see a picture of Neil's part if possible. I have discussed this with Neil and he has not mentioned it to me. Is his part for a turbo charged motor?
In addition, the actual fitting of the World Cup plenum to the barrel units is a fairly simple job. To have one plenum fabricated for each side and then add a crossover would be a lot of work.
Then again, this is fairly new to me, I'm always looking for more information.
Here are some pics of the RSR type and some fabricated plenums. I believe Loren Beggs of 911 Design did the work.

I am taking the liberty of assuming you are asking why "barrel" type versus "butterfly" type as used on the RSR is our present choice.

I have attached a picture that Neil sent me some time ago when I was looking into this. I have also attached some pictures of what I ended up doing. Sportec had some nice cast plenums on their SPR1 but it seems they won't sell you them without the car.

Looking good. Can't ignore the amazing fabrication work!
Couple of quick questions--what is the scheduled first drive date as of right now? How many miles are you expecting to put on the vehicle each year (street or track)? Also, how often are you expecting to have to do rebuilds (re: the engine)? Hopefully not too often considering how much time and effort has been required to get it to where its at today...but at least you'll have a much better idea on what needs to be done.
Take care

I hear you on the flow of the roller type barrels.
I have attached a picture that Neil sent me some time ago when I was looking into this. I have also attached some pictures of what I ended up doing. Sportec had some nice cast plenums on their SPR1 but it seems they won't sell you them without the car.

I just returned from Monaco and I didn't do any answering.
I see what Neil did, however we are still using nitrous and the above in my opinion just doesn't have the same mixing chamber.
