What will new cams do?

[twilightprotege]

midnightracr, i'm not sure on this, but i heard (could be me just misreading something) that perf's cams are going to be just regrinds....can anyone confirm this???

either way, they probably didnt spend weeks testing the specs. they probably had 3 or 4 specs made up and tested those. could be easily done in a day. they would have just used educated guesses and cam programs to work out what is best. i would REALLY REALLY REALLY like to know if they had the head flow tested to get perfect cam specs with the stock un-ported head!

thanks too to moeed and iluvmacs honeymoon is during this week (not now) in the gold coast hinterland (i say gold coast hinterland because most people know the gold coast in queensland, australia)

macs - the reason i said 280 is the max duration at seat (the cam will be more duration, but because we have solid lifters we should only ever talk about valve events not cam events), is like you said - it would move the power band way outta our rev range and the low end would just die in the ass. max amount of lift out engines could sustain (with new valves and valve springs etc) would be about 0.450", but why? 0.350" is enough when the duration is right and you wont have valve float issues with the stock valve springs

way to go twilight.... its awesome u got married.... good luck and have fun on the honeymoon, Perf told me that they were billet grounds... at least i think he did. As i said above if he had them reground he wouldnt be able to get too much over stock... although it would explain the price $550 for a set... ouch.. Also i wonder where he got the billet exhaust cam from since u said thta u had to get a billet intake and make it into an exhaust right? hey either way at least there are some options now.

I was just curious. I love the sound of a loping idle, and I really want to shift the torque curve much higher in the revs, so I'm trying to get as much info as i can right now.

I'm not going to get anything soon, since some new cams are supposed to be appearing, and I don't have engine management yet.

well my cams came from the blanks that mazdamotorsports sells (got them through protege5online.com). they were pretty much the limit of what i could grind them out too. and yeah, both intake cams, exhaust just repinned.

for $550, i'd hope they were new cams. i wouldnt be happy if i'd spent that much and still had to buy new shims.

macs, dont worry too much about having to have a new ecu to get power out of cams, yes it will help, but it's not a must have

I'm just waiting for a solid, tested set of cams to match up to some tri-point adjustables..then i'll move forward..
