CJV, still following all of this and having lots of fun doing so!

When you say the crank journal radius is small to take the raised redline, do you mean the crank lobs have been decreased in diameter? I am a little lost here on what exactly was done......

 

Garey,

It is the large end of the rod that connects to the crank shaft. The 996/GT3 journals have a diameter of over two inches. We are using exactly two inches. Hope that explains it better.

 

Some additional information. Our pistons weigh 312 grams each.

Not sure anyone has an interest, however if you do, these pistons, wrist pins and rings are now available from S Car Go Racing. Contact Rob King for further information.

 

Wow that's some PIA!!! I'm glad it's not me paving the way with this stuff... I wish it was ready by July 1st so you could come to the track event with it. However you've got PLENTY of other cars so how about you come along to it anyways? At worst you could also check out other turbos and give advice

 

Alex,

Even if the motor was in the car .............. it wouldn't be broken in by July 1st. Actually, we are suppose to have all the internal motor parts back from HPC Utah by June 2nd. Won't have the turbo's and the headers back from HPC Oklahoma City until about June 15th.

I'll post some pics of all the parts prior to assembly.

 

Looking forward to those pictures Chad.

 

03-turbo911,

HPC Utah should be returning the pistons and bearings by the end of next week. As soon as S Car Go Racing receives them, Rob King will start assembling the bottom end.

 

CJV--

Sorry for the ignorance, but I have a few questions.. I have tried my best to stay awake and get through some of these pages but there are just too many!

1.) What are you trying to accomplish here? By the looks of it a porsche with 1000+ HP? Sounds like you had one awhile ago but had problems with the internals not being able to hold the power or something?

2.) How fast do you expect this car to be 0-60, 1/4 mile approximately when it is finished? What is the nickname for this car, what was the car origininally?

3.) And HOW LONG have you been working on this thing!? I wouldn't be suprised if you got over 50% of your post count in this thread lol

Thanks man! Seems like a very special project you are doing... would love to knoe more about it!

 

I hear ya- it's going to be some ways off... Well you're still invited to come/drive in any one of your "other" cars I'm sure there'd be plenty of people from the board that'd love to meet you in person anyways

 

rduffyt,

This is only part of it. There was thousands of posts and replys prior to this on Rennlist and prior to that on Funcarsonline. The last motor had about 800-850 on stock internals. Yes, we had a little set back ......... we bent all six rods.

How fast we expect the car to be will depend on how much octane, boost and nitrous is applied. Anything below 1.9 and above 148 will be an improvement. The nick name is "Killer Angel" and she was a 3.6L turbo.

We have been working on her since she was delivered in July 2001. Alot of the posts don't get replies. Probably because once we started to modify the internals past the rods and the oil pump we were in an area most others would never go. I had offered to stop the thread but it seems to have a small following that wants to see what is being done and where we end up.

We are building a motor designed to hopefully withstand 1200-1500 hp with a redline just under 10,000 rpm's and be streetable. The upper end of the power band will arrive with about 2 bar and a 250 shot of nitrous. The everyday driving bar will be 1.1-1.2 bar and around 900 hp without any nitrous.

You know, everyone wants to look at KA's motor, but her weight reduction and handling really rounds her out and gives her alot more appeal to me.

 

Thanks for the nice detailed reply! Now I am an avid follower

Sounds like a nice project, already can't wait for it to be finished and to see pictures of teh actual car!

good luck!
Ryan

 

Thanks Ryan,

Not going to have any news until sometime between June 5th and June 10th. Then things should really start to pick up speed.

 

Maybe the second most advanced piston Glad they were able to make a set for you quickly. We had CP manufacture our engineed pistons last year and we have had great luck with them. We had a few pressure tested to 1580 HP! Those pressures are almost double what the OEM piston can handle. We should have our latest beast fired up next week and we will give that Tilton clutch a workout. Speak to you soon

 

Yes, Todd deserves credit for steering us in this manufacturer's direction.

Todd,

What I was refering to when I said most advanced was:

1) The exotic aluminum used so as to withstand the combined temperatures of the nitrous and the boost we specified. This ran the cost of the pistons up alot by itself. We could have gotten by with alot less expensive material.

2) The depth of the top ring in conjunction to the 9.2-1 compression ratio we are using. From what I have seen others have lowered their compression ratio alot more to get even more boost. We wanted to keep the compression ratio up to keep the throttle response up in the lower rpm's (2000 thru 3800). The design of the piston was derived from countless mock ups using our cams and the Woosner/Porsche GT3 pistons we used in our mock ups.

What compression ratio did you choose for your latest monster motor? Do you happen to have a pic that could be shared of the CP piston EVO designed? I realize certain things are proprietary, so if you can't that's OK.

3) The depth of the valve pockets to handle the larger diameter valves with a very radical lift. This motor is designed to turn just under 10,000 rpm's.

4) These pistons are not 100 mm, they are just a little bigger. We decided to use the 102 mm bucket size.

I believe we are using the same or very similar clutch. I wish you all the best with your new motor. EVOMS is kind of like Star Trek. To boldly go where no tuner has ever gone before.

 

Chad it has been a pleasure following your car over the years. I have the luxury of seeing the build in person. Both you and Rob have been very resourceful in thinking outside the box. I have learned a lot about how far I can safely push my own car (993tt). Look forward to the results of all of your madness.

Todd please don't ever back off or Chad may lose his competitive spirt. I think both of you guys feed off each other.
