Hi Chad~~~nice to hear you are making progress. BTW is that the same Loren on Renntech?

 

Chad - I'm missing you not being involved in some of the recent big dog action. Must be driving you nuts.

 

I do not believe it is the same Loren. Loren Beggs is from Montclair.

 

Zippy,

I don't worry about things I can't control. We'll be there in due time. Besides I really enjoy watching Alex reel all these guys in.

 

Zippy,

It is strange that your mentioned this. I was on the phone with Rob King of S Car Go Racing today and he said to me, "guess who is over here looking over your engine?" I replied ........... Alex? He said yes and I said put him on the line. We talked in full detail for along time about his motor and what could be done to harness a few more of his ponies to the ground. It was a good conversation and I believe his car is about to become even faster, if you can believe that.

I was set back a bit more when he said that after reviewing KA's motor that it was at a level all it's own. That was real compliment coming from him. He also felt that we should use the 35 or 40 GTR turbo's and offered to let use try his car just to get an honest feel. I was very appreciative of this most generious offer but the real compliment was yet to come. He said that KA was the inspiration for his current 996tt project.

You know Zippy, 6speedonline has some of the biggest dogs around. Contrary to what members other forums like to say, these big old dogs share information and root each other along. It's really a great feeling.

Go VRAlexander!!!

 

What do you guys think about GT40R turbo's? We are seriously looking at them. It looks like KA's motor would be more than up to the task.

 

Which turbo's to use. I never thought this would be such a difficult decision. VRAlexander was by the other day to review the motor. He felt that nothing was left unturned and this was going to be "the" motor. He offered to leave his car with me sometime next week to see how the GT35R's performed. Alexander believes we should use GT40R's and Todd Knighten previously made the same comment.

Then there is Rob King, he keeps asking how drivable do you want you car to be? Rob's choice is the GT30R's and I understand these are the same turbo's Loren Beggs of 911 Design has utilized in his GT3 turbo race motors. I understand Loren is presently developing 870 rwhp with his motors. Rob hasn't as of yet driven Alexanders car and I am hoping Alexender will allow him to. It would be interesting to see weather or not Rob changes his mind after a test drive.

Then, we have one other item to factor in. KA's motor isn't a 3.6L. Every part has been strengthened/re manufactured and in many cases additional hidden power should be realized. The question is how much more turbo will she be able to handle and still be drivable/responsive through the whole rpm range?

As an update, Rob is talking about having the motor completely assembled by the end of February.

 

Head gaskets.

We have chosen to use EVOMS's head gasket because this head gasket appears to be able to accomodate high boost pressures and not burn through. That is the plus. The minus (depending on your outlook) is the gasket is approx, 22/1000ths thicker. The stock head gasket is approx. 20/1000's while the EVOMS head gasket is appox. 42/1000's. This translates into a compression drop of approx. 3 points. The stock compression is 9.4 to 1 with stock head gasket or 9.1-1 with the EVOMS head gasket.

In our situation, when we designed our pistons we opted for a 9.2-1. If we use the EVOMS head gasket we would has a 8.9-1 CR. We like the EVOMS gasket so it looks like we will cut approx. 22/1000's off the bottom of the barrels so as to maintain the 9.2-1 CR.

 

Rob's probably erring on the side of caution. You will, probably, be never satisfied with the Gt30's and it'll never end there. KA has a unique engine and it might need a unique turbo to take advantage of it.

 

Good to hear about the progress. It is nice to see the true community come out with you and Alex. When KA is done, I would love to see that race.

 

Porscheboy16,

If you want an honest opinion as to where KA's motor stands compared to all other motor's out there ............. ask Alex, he's had a full view.

As for a race ............ well we would both win. I don't believe with KA's smaller turbo's, NOS and suspension/drive train that there will be anything even remotely as quick. As for brut power from a roll I don't believe Alex will be beat.

We expect to be attaining full boost at approx. 2400 rpm's and maintain it through 8200 rpm's. The car is being built to handle 2.5 bar, however we expect to attain approx. 900 rwhp at 1.2/1.25 bar. To use much more boost with the GT30R's would be overboosting them.

 

The heads have just been sent out for a little intake work and assembly. I'll report on the new flow tests next week. Should be somewhere around 280 cfm.

 

How does that compare to stock? Wha t would some minor head work net on stock heads?

 

Zippy,

I never flowed a stock head, however I'll find out and get back. My guess would be somewhere below 200 cfm. I spoke with VR Alex the other day and he port, polished and used larger valves to attain 360 cfm.

Porting and polishing will help, but you can get only so much air flow through the stock size valve. If I remember correctly stock size valves are 32 and 35 mm while stock Cup size valves are 37 and 42 mm. I believe RSR heads are 37 and 43 mm.

 

Custom Pistons designed for higher lift, longer duration, high boost and NOS.






The ductile iron barrels have been cut, the mockup is complete, the S Car Go Racing modified intake and exhaust cams work. We are finally ready for assembly.
