Well if they are using Ti, thats piss poor gimicky engineering. As an engineer, Ti would be way down on my material fo choice list for a spring.

I guarantee you that no CART, F-1 or other engineering intenstive racing series use them then!

Well, this may shock you as much as it did me, but in the December 2002 issue of Racecar Engineering there is a Ferrea ad that actually lists Ti springs.

I haven't had a chance to check out the details yet. Crazy.

I just learned of titanium valves! Big dog racing obviously means big dog bank account.

Hmmmm - drag racing springs last 20 passes - that's less than two minutes at full fury. Ti might be just fine.....for about 10,000 cycles. F1 engines see 1.2 million cycles per race, good SCCA motors about 420,000 per weekend, maybe 2.4 million between rebuilds. 150K mi street cars see something like 10-15 million cycles. It's all about replacing the part before cyclic failure breaks it. NASCAR engine shops are fanatics about this stuff.

Going fast is about having more seat time than the other guy first, talent second, esoteric mechanicals come in waaaay later. when you're looking for 10ths - look at the driver. When you're looking for 100dths - look at the car.
