I want to have a car that in the end can put up with DE usage and the occasional weekend drive.

So it has to be streetable durable and quick.

I currently ahve a Speed Force MAF and their Stage 1 turbo. ALong with 30 mm tbars and 400 lb coilovers with Koni Yellows on all 4 corners.

The suspension lacks sway bars.

My skill level is novice (Blue Group).

Did I miss anything Chris?

why are the sway bars off the car?

Im just curious about one thing, When you have a scaper, and all the doodads that prevent oil sloshing how do you get oil under the pistons to cool them and lube the cylinder walls? the 968 has jets the 951 does not... Could this be a cause of so many scored cylinders??

They aren't. They are just stock.

Sorry I wasn't very clear.

I spent quite a bit of time recently talking to a guy who does all the work on one of the fastest 944 Turbo PCA E cars in the country. He's a former Porsche mechanic who used to work in dealerships, and the race cars he works on today are really well prepared. Anyhoo, he mentioned they had run the same motor for about 5 years without spinning a bearing, so I started quizzing about all the things they had done. He may have been holding back, but he claimed it was a stock crank and that the most important thing they did was watch the oil temp very closely. He said there were a number of times the driver had to back it down because of oil temp, but the engine never popped. I'm installing a temp gauge now!

What was his max oil temp recommedation?

and where did he locate the sender?

simple - you build it right the first time. You don't install new rings in old bores, you use twin oil coolers, you make sure your cooling system is top notch, and decide on your max rpms and get valve springs accordingly. You take care of the car on the track, especially at DE's, it's not a race. That sounds kinda of general and broad but if you band-aid it, you'll get band-aid performance. Knock on wood, our track car as seen three flawless year so far. I just changed belts, All fluids, changed head gaskets just so I could inspect the bores, and she's ready to go again.

Keeping the revs down is the big thing. don't exceed redline, even if your chip will let you. Go for amsoil, redline or royal purple oil. If you use Mobil one, you would want their M1 for motorcycles.

>>What was his max oil temp recommedation?

That would definately have been the next logical question, wouldn't it?

I think I was so shocked by the statement that they ran a rocket racecar for 5 years with a stock crank and no problems that I was speechless. That's my excuse anyway.

I hear all the talk about keeping oil topped up and limiting revs. I'd like to hear from anyone here who has tracked a stock car hard for years on R compounds and had success with this method. Of the 20 944 and 944T guys I know, only one made this method work. I tried it and spun #2 the second season on R compounds. The car only had 80K miles.

I spent a lot of time yesterday speaking with my mechanic (who raced numerous 944 spec cars) and oil temp was a big thing we talked about. His keys to keeping from spinning a rod bearing were 1) keep the oil temp down and 2) keep the revs below 6k. The times that they spun a bearing were when one or both of those limits were broken.

The temp he mentioned was 250*. He told a story about how one of his cars was in 2nd place, and the oil was up to 280. He told the driver to come in, but the driver refused. Oil kept going up, and about the time it hit 300* he spun a bearing.

I am working on the same issue right now. For reliability I am going for new rod bearings, crank scraper, KISS secondary oil cooler, 1989 oil pan with improved baffle and oil pick-up, all new belts and hoses. For power the mods are limited to a rebuilt K26-8 at 15-16 psi and chips with stock rev limit, in addition to the TiAL wastegate, test pipe and catback already on the car. I want decent power in a reliable car.

quiet understandable, hey, but you scored one good pearl of wisdom

Great info., keep it coming....
