Real Steel/Viper Typhoon Cam and other bits
Discussion
Can someone in the great body of knowledge that is PH answer a few questions for me...
The Typhoon cam, is it any good? How does it compare to, say, an MC1? What is power delivery like and what ultimate power is likely from this cam on a 3.9/4l engine?
Also, Rhodes bleed down lifters, what are the advantages of using them over standard tappets etc?
Regards

If my data is correct, the Typhoon has 276° inlet / exhaust advertised duration.
Lift is 12.19 mm for both. That is not far of the Kent H218, which I think is very close to the MC1. It does not look like a great deal of difference on the paper.
I used to have a Typhoon in a 3.9 with stage 2 heads, Weber 500 carburettor and Edelbrock performer manifold in a kitcar. Did not think much of it though. Flat torque curve but not much top power.
But then again, my heads and intake system were not the best either.

As I understand it, they reduce the valve lift a low RPM's - which effectivley makes your cam look smaller and hence improving idle/low range.?
eliot.
you can really compare cams on what is written down on the paper, for instance all they normally give is duration/lift and opening and closing times, i have just had a cam ground which is 320 deg of duration but more importantly full lift hangs open for 20 deg longer and at 1 point has 100 thou more lift than a normal 320 deg cam that kent grind, i pesonaly havent tested any of the real steel cams so cant comment, the roads lifters to be honest are very good at taiming a wild cam and cant believe they are not used more than they are! they do indeed bleed down at low rpm to make the cam feel like it has less lift, however the downside is they can sound very tappety!
