Is the 3.8L RS conversion worth it?

I hope you have an aux oil cooler. Willow in July is tough and you may not be able to run for long. Also, you can run most Firdays at Willow as a test day. $150 for one car and one driver, as I recall. First time is another $75? for an annual test card.

Unfortunately, when I upgraded to the 3.8L kit, I also at the same time added Varioram. I really felt a difference, also because of the much better torque curve. But a lot of the improvement certainly came from the Varioram enhancement. Guess if you have a Varioram engine, the improvement will not be quite that noticeable, as Hank says...
Afterwards, I then did the RoW gearing. Subjectively, this was a similar jump in performance as the prior, much more expensive modification.
BTW: In Paul Frere's excellent book, he mentions the 911 Cup 3.8 RSR used in the Japanese GT3 class. It developed 340 hp at 7000 rpm with a 7400 redline. The higher hp, compared to the European Cup car, came from a slightly different camshaft, but essentially from the absence of the exhaust catalyser, he says.

Mark - we do have a Turbo S aux oil cooler. Good point about Willow Springs in July, though. We were there in April and it was perhaps 80 degrees at the warmest time of the day. The oil temp held at the first notch or below all day. I prefer not to do open track runs as I value the more controlled environment of a DE.

Bill, I think I'm 170 lbs over the limit. The gearbox hurt me too. I think you would go through three to my one. It's true that doing everything at once and dynoing it would be the right way to go. My car has add ons thrown together. The exhaust and headers probably hurt HP but the weight savings make up for it. Never dynoed the car to see. YES I am ready to lie cheat and steal for that upgrade.

Jerry - when you say 3 to 1 are you taking about the back straight. I was getting into 5th there and existing the keyhole in 2nd. This was the same as I did in my 996. You could not be in only one gear there. At Sebring Greg and I were shifting at about the same place.

Jerry - Also if you have not done the RS gears. I would definitly do this before the engine, and delete the extra 170 pounds would be the first thing I would do. The engine upgrade helps but not that much.

Bill,
You are not helping.
I have enough trouble staying near Jerry now. I think he needs to add weight.
I do agree the gears and weight are probably a better place to spend the $$ first.
Jerry was so fast he was coming out of the keyhole in 4th gear, so he only needed to shift once on the back straight.
Did your shop install the Woodruff (sp?) keys or pins for the camshafts? There have been a couple posts on the subject and Steve W. has suggest doing that.

Jerry,
I think Larry S. has some aluminum doors ask Brian next time you talk to him.
Hank,
How much weight savings do you get with the aluminum doors, and hood?
Why don't you use them on your RS conversion?

If it doesn't offer at least a targa top, I'm not interested
I feel the same way about automatic transmissions, just isn't a sportscar that way. I understand what the post is about, that's why I recommended a supercharger

Greg:
I weighed them a while back and posted the results, but I don't remember the numbers now. I think the aluminum hood weighs 17 lbs and the doors weighed about 55 lbs if memory serves. I don't think RS doors are aluminum, but I may be wrong. As far as I can recall, there are no aluminum doors for the 993 series of cars.
