1. JUN if you can a) find them b) afford them

2. Cosworth (I love mine!)

 

The Forced Performance 4R grinds are made specifically with stock valve train compatibility and EVOGreen turbo performance in mind. Some people might think they are "huge" cams, but they run very well on stock ECU, Autronic, AEM and Motec. We've had all of those ECU in the car over the last year with the 4R grinds in place. Also with the stock retainers and springs in place.

4R is great all around cam, dont let the big lift numbers scare you away. 9sec9 is popping some in to replace his Jun272 grinds and increase power.

BOOST ON!

S2's are a great cam.

 

Robert, you gave my secret away. We are changing from the JUN 272's. As most of you know, we've had very good luck and numbers using the JUN's. Recent tests and our own 'profiling' shows that the 4R should make more power than the JUN 272's. It's nice to have a sponsor for parts, but still, our ultimate goal is to run as fast as we can. To do that, we have to make a higher average powercurve. The 4R's will be installed on the car in the next couple of weeks and hopefully track times immediately thereafter. From the information that I've been looking at, the 4R's are a no brainer. Forget the 'hype' of some of the other cams. I know that recent tests show this and that, but I know that some very good information is being overlooked. Smooth, higher-average whp is what we're after.

 

cams do miracles
