Great job petevb....I really love it...

High pressure area - for intake. Same principle as the current GT3.

...One of the cool things about Porsche's family of cars, particularly the 911, is all of the fun things that can be done to them.

Consider a car like mine from a few years ago... mid-70's 911 with composite later-model bodywork and a modest interior, a cage and a weight of about 1950 pounds. Then consider (unlike mine) a 3.8 twin turbo motor installed in it. Who knows how much power-- north of 700 for sure. Now this car also has heat, and is driven, not infrequently, on the owner/builder's ~45 minute commute to work (on street tires, not slicks). Now consider that this car is also raced, and it shows up at PCA Club Racer at Laguna and beats all of the other cars, including highly modified GT3 Cups. Now the car has different body work, an engine with slide valves and is active in vintage racing.

^ Excellent comment.



PVX beast needs a couple of goPro's mounted on board to shoot something like this...

What a great build. I like the attention to weight distribution and shaving weight. I have thought of building some tail lights for my project and also moving more weight forward.

I especially like the oil tank, it was something I wasn't thinking about. I too will be moving my engine forward. I am interested on how you tied the front side of the torsion tube into the chassis. I was planning on picking it with the roll cage.

North hollywood speedometer does gauge conversions as shown on Pete's car. But there are others that do that too.

Hi,

Amazing work!

It is hard to believe that these two little radiators are able to keep the engine temperature down.
Are there any more rads in the car or just those two?

Many Thanks!

[not_hans_stuck]

Pete,

Did you run the cooling tubes through the rockers? Did you do that before the bodywork, or after? - please say after...

I'm doing a Renegade conversion and I've decided to run aluminum tubes for the coolant runs.

Thanks,

Hal

With the front fenders off you can make the holes and run the cooling tubes after the bodywork is done...

Just the two, but they are high quality, thick, and need careful ducting and four fans to keep temps down in traffic. They do a good job at speed, but it took a couple tries to get traffic temps where we want them on hot days. Doesn't help that the cup engine idles at 2k rpm, and throws enough heat that the headers glow red at idle...

Link to the 911 world article for those that are interested, btw:

I'm slowly working through some potential suspension changes in all my spare time, and a couple other changes. Learning some interesting things, I'll start a new thread at some point...

[petevb]

Any idea why it won't let me edit my old posts on the previous page to fix the pictures? In any case, here are some of them again:

The car looks great Pete!

Pete, do you know the ballpark weight difference between the water cooled gt3 motor and an air cooled 993 motor. The car looks awesome I think I saw it out at point Reyes over the summer.

Thanks
Ken

nice

These types of builds hook me and makes it difficult to stay focused and near the edge of the slope and finish off with a stunning piece.

Are those last few pictures posted with the 19 rear wheels?

[redridge]

wow! speechless....

Ken, vs a 993 VRam you're looking at ~48 lbs empty, ~56 lbs including water weight within the motor, more like low to mid 90s with the full weight of all cooling systems included (also accounting for less oil cooling weight), though much of that is forward in the car and so doesn't hurt the weight distribution.

No, those are the 17s. The 18s and 19s look huge on an early car:

[itsnotanova]

Do you have any pics without the tape on the rear? I've been thinking about 19's for the tire/wheel selection but not sure they can look good. Did you go back to 17s?

[kojo911]

Thanks Pete, love the car.
