350 HP Potential for CIS

[Todd Phenneger]

 Can you explain Why you dont want more push out the exhaust valve?  Wouldn't this decrease lag.  Are you thinking that above 4k RPM at full boost it will be to hard on the Turbo?  

    I'm pretty sure that Chad Clark ran a 272  (err, wait,  now I seem to remember it was a Piper 268 cam).   What is the duration on the Stock MC cam, do you remember?  Also, do you mean Elgin is also doing a 272 for you?    Will you try that in the MC for a bit and see what it does?

   gary, what cam are you running?

thanks

    Todd

<< Javad,
I'm VERY curious as to the results. I know that a Shrick 272 had great 
results in a couple turbo cars. Can you explain how you came up with the 
264/260 dimensions you did? I havent' put MUCH thought into this yet other 
than I know I'm going to Elgin for it and I know I want a Cam. I had planned 
on basically copying the Shrick cam but maybe I wont. 
Anyhow, I'm Very curious to hear the results. l8r

I talked to John and mentioned it was for a turbo car. We came up with 
the asymetrical grind with a little more aggresive duration on the intake to 
reduce push out the exhaust valve. This cam will slightyly soften the bottom 
end, and may increase turbo lag a few hundred RPM, but hit 4000 RPM, and son, 
hold on, that little I5 is gonna scream for the rev limiter!! =)
I would not use a Shrick 272 cam in a turbo motor unless it was a race 
car, you are going to be pushing boost out the exhaust valve up past 4000 
RPM, a little aggressive for forced induction IMO. 
Elgin is doing one of each for me, however, so I can let you know for 
sure...
