TRex Cam What do you have to do to get this cam in....I dont mean like "how to," but like, what do you have to change(i.E. Valve springs) Also on an A4 with 4.10s what type of 'Verter would you recommend???
Thanks
Thanks
with most large cams...even most mild ones youll make peak tq upwards of 5000 rpms...for me i could only breakstall mine to mid 2000's thats not even close to that...id rather you be in your powerband than to depend on the gears to pull it through the powerband.

For a street car you would be much happier with the performance of a cam that will maximize power from 2,500 - 6,000 than a cam that produces virtually no torque below 4,000 and peak power at 7,000. Trending Topics

but all things considered it would win races...power under the curve is all fine but if hes over the curve for an entire race who cares? JMHO LS1 Tech Stories

Well, whats a good cam that does what you were describing above??
Thanks
check out tsp's 225 or any of the 224 cams...they all peak between 6200-6500 and will give you a decent amount under the curve...but even the 225 doesnt make more power than before the swap till 3200 rpms from the looks of it...my 231/237 didnt make power till after 3800

thats the most mis-used line on these forums.
how many times does your car dip to 2000 or 3000 rpm during a drag race?
its power under the curve IN THE RPM BAND THAT YOU RACE IN that wins
check what rpm your tach drops to between shifts.........any power/torque under 3500-4000 or so rpm is useless in a race. the higher up the powerband that your torque peaks, the higher your power will be and the faster you will accelerate in your racing power band.
unless of course youre racing to see who can pull that stump the fastest.

as far as i know its avg power in your powerband that wins races not power under the curve. FormerVendor
