Default Re: how much ET improvement with cam only?

There are way too many variables to say how much a certain cam adds. Gearing, A4 or M6, which torque converter if A4, weight, weather, etc. I dropped .4 from a cam and converter swap (Vig 3200 to a Yank PT4400) in worse conditions w/ the same raceweight. If I was in the same conditions, I'd say the cam/converter swap was worth .5-.6. You should be able to gain around .4, give or take, with just a cam swap (in the 222-224 duration @ .050" range) if you have the right setup.

obviously it would be assuming same weather conditions. basically, you run a number, swap the cam at the track <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> and run again.

I saw roughly around .2 and about 3 MPH with my T1 cam but I had a slipping clutch so who knows.

Default how much ET improvement with cam only?

looking to get a cam- what kind of ET are people seeing over stock cam? something not too large, like a 222/222 563/563.

i have headers, ls6 intake, and tuning.

thanks <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
