Just curious if anyone has the power/torque etc etc difference between the two. I have been very upset with my power/times with what I have. I currently have the 264/272 and am thinking about buying the 272 intake cam. But I am curious to see what the differences that can be expected between the two. I know the idle is rough, my Bro has the 272/272, but am more wondering if it is worth getting the 272 intake cam... thanks!!!

What's happening with your power/times? I'm thinking about the same setup that you presently have. How mucg better is your bro's evo running?

There should be no problem with your cams. But just for information's sake, at what setting do you have them installed? In any case, those cams are capable of making a good deal of power.

I don't know which type of dyno you used to come up with those numbers (it does matter), but they don't look bad to me. Also, I don't know if your Dynoflash was actually done with your car on the dyno, but if not, I'd venture to say that you may find a bit more power in the programming.

If you do switch over to a 272 intake cam. I will have one for sale when I install a new 264 intake cam next saturday. I will let the 272 go for $275 shipped.

It was at Pruven, Dynojet. I do have 18's and stock IC piping. And it doesn seem like Im about 20-30 WHP lower than most who have my setup. From everyone Ive talked to with my basic setup ro very close, most are running 12.3-6's, and have about 340-50WHP. I am alos getting my car raised a bit, diff springs from the 2 / 1 3/4 inch drop to a 1 1/2 / 1 drop as well as my alignment has been off for a bit which is getting fixed next week. And all of my flashes were done on the Pruven Dyno. And my car was low to begin with on my original dyno with a full Tback w/HF cat, that was only 230WHP. Anyway, can anyone really answer my initial ques about power diff between the 2 setups?? Thanks.

Check this link out for a comparison between cams. This should answer your questions.

Wow, so it looks as if there is no diff between 264/72 and 272/72. Maybe I should save my 300$. Seems strange though, cause then why would so many street "race" EVO's prefer and use 272's when the idle is much rougher when there is no power diff and a lower torque. Strange..........

Havent driven it yet. Its out of commision waiting for the Buschur dual ball bearing turbo....

This is a nice comparison, however:

(1) The most objective way to test the difference of the cams is to tweak the A/F ratio while conducting the dyno test so that all of them are equal, and then record the numbers. The article doesn't indicate anything where this is concerned, so it's entirely possible that more power was to be had in at least several cases - especially with longer duration sets.

(2) The comparison does not take into account the benefits of altering the angle of separation via cam gears, which can significantly alter the low to mid-range torque of cam sets with longer overlap.

Of course, a test thorough enough to take (1) and (2) into account would be lengthy and expensive.

If only it was all crystal clear, but unfortunately, it rarely ever is.
