Ams Evo Cam Test
also for those who didn't read the turbo article, they mentioned about how too aggressive of a cam wears out drivetrain parts. some cams can wear out parts in 5000 miles!!! cams w/more than 12mm lift run the risk of smacking the valve cover. alot of people here in the US focus on PEAK power, & should focus on USEABLE power. for example, a guy running a 2.4 w/a gt37R only has about 3000rpm of useable power, vs the guy w/a 2liter & same turbo might have up to 5 or 6000rpm of useable power assuming both blocks built...
the best way to shop for a cam is to look at the curve, not the specs. u want a cam curve that looks like an arch, not a pyramid. tomei is solid yes, & most people running 350-600whp could benefit from the tomei 270 pros w/out losing as much low end drivability. i used to want tomei 280's until i realized they only make sense for drag monsters pushing 600whp+. instead i will stick with JUN 272's or Dentist Mapped 276's which would include all JUN drivetrain internals which brings up my other point. alot of ppl 1/2ass cam installs & then wonder y their car runs like bubu. just like a turbokit u need all the supporting parts. a cam job done right would take an additonal $3k in extra parts to extract the most power...
You are very correct, that was a little more in depth on what i said earlier in this thread. the point of this test was not to pick the cam that makes the most peak power but rather to use this as a guide so customers can go back and view this thread when looking for a cam that suits their needs the best.

Will this guide still be usefull for other applications such as stock ix turbo? (spool and curve wise)
I think its awesome you guys are doing the testing for the community. Big thanks!
