what p/c combo r u using

 

He has a gt2, thats a gt3 with a turbo engien so its the best car to start from

 

Thats what im looking in to, buying a RSR and swap out the engien for a TT one

 

I believe this car will still be registered for street use...

 

I looked into purchasing of an RSR, but they r hard to find and then you don't have the street capability. I will tell you that this car will complete at less than the cost of a new 997 RSR, but you could easily purchase a very nice Carrerra GT for less than I have in this car. But that is not the point. This has been a very interesting challenge to build and keep street legal. I will not guarantee its registration in every state, but it will be, and is, registered in Arizona. The engine is not a turbocharged RSR motor. I will tell you that many of the parts are from the RSR motor, but there are an equal number of custom fabricated parts required to make it all work properly. There are 5 versions of this engine in track cars and they have been getting 65 to 75 hours before rebuild. That is amazing considering the power and torque. This is the first street motor and we are testing a new turbo design that has not been used on the race motors.

As for the 3.8 conversion; we are using Mahle cylinders with a custom made piston and ring set..

The 840whp is conservative, and frankly, is based on the 3.6L race motors. I will publish the actual results of the 3.8L design with the new turbos when the car is dynoed in a couple of months. I would guess an actual of close to 900whp. We will see.

 

I am speechless.

This is an amazing.
Thanks for sharing

 

the wing looks a little shopping cartish but the car is unreal.

 

insane build! extremely bad ***

 

So in your opinion, every how many miles ( street miles) will you have to rebuild the motor?. You see, I had the choice of going with a RSR head but chose not to due to the frequent rebuilds required. It just did not serve my purpose. So I opted for a slightly used world cup challenge head with GT3 cams.

 

Mark, the RSR engine would need to be rebuilt quite often if it is driven like it should at high 9k RPMs and huge stress of a race environment, many components go by number of hours, but that is with certain race usage. Otherwise it can be driven as long as any 996TT engine and longer, provided it is used the same way, albeit with some more maintenance items.

 

This is a friend of mine's RSR motor after a Sebring "mishap" two weeks ago...

NOT GOOD: Someone hit him while he was down in the grass and the rest is tangled
RSR.

Absolutely amazing. That thing is Porsche sensory overload!!

 

markskiI tend to agree with Jean. The entire engine is rock solid and its longevity clearly depends on how you use the car. I will not use this on the track as much as one might think. As a matter of fact, I am starting a sister project to build a similar Speed GT World Challenge car that I will race only. Loren Beggs and Cary Eisenlohr are going to build that car as well. It will certainly be very different due to the WCGT rules.I would guess that the current car will see some leve of inspection and rebuild every 200hrs or so based on how I will drive the car. You certainly do not build a car like this if you can't afford the 40 or 50k it takes to rebuild the motor every 200hrs. It would not make sense.

 

****. I guess I'm out then!

 

I actually asked because I did not know... I only recall my tuner having both heads in his hands and opting to stir away from solid lifters in the RSR head...
best,
