Well, with the recent break up, I have decided to spend some more money on the EVO, and I decided next on my "grocery list" is a set of cams. What do you guys recommend? I have been trying to decide between 272's and 280's. Keep in mind this car is mainly just a street car, I hardly ever get to the track, and my over all goal (for now) is ~420whp on race. I have heard the 280's can be a bit much for street cars without some kind of stand alone, or something along those lines. Now would it be that bad if I'm having the ecu flashed again by Turbotrix? Or even if I eventually get the E-Flash from Al? Whats the biggest differences (hp gain, tourqe, etc) between the two? Also, lastly, yay or nay on Comp cams? From what I have been told by a few people, they are almost exact to HKS', but at a fraction of the cost. Or is there even another brand I could go with that I have overlooked? Thanks in advance guys..looking forward to spending more money..lol

 

Dude, I don't won't be an A-hole but, SEARCH.

There have been tons of these threads and I'm pretty sure almost every conceivable cam question has been answered at one point or another.

 

280's make more top end, not much more though. You should be able to get them to work fine with a reflash.

Comp's are not copies of HKS cams. They have a different LSA, lift, duration, and ramp.

I have Comp 272 and love them. The car passes emissions and makes good power.

 

I might be going with HKS or Buddy Club 272/272 soon.

GSCs are the ones that are supposedly just like the HKS' for about 100 bucks less for the set

 

So are Buddy Clubs, plus they are made by Tomei.

Comp cam 280s :-)

 

i really like the revolvers, expensive though if its just gonna be a street car. Honestly, if turbo trix is gonna flash it for you, have them recommend a set for you. A lot of times you can get better overall results if your makin the right combos on parts, not necessarily getting the "best" of everything.

 

How about low end? I was told with the 280's you will gain a little top, but sacrifice low end torque?

 

If you are seriously wanting to achieve 420whp then you dont want to leave any potential on the table...Go for the major power givers...get the 280's(whichever brand you wish) and a set of sprockets so as to tailor the powerband to your particular requirements. Al @ Dynoflash can get them to idle smoothly and I imagine that TT and Jester can as well.

 

With cam gears you can dial 280's in to maximize midrange torque and fast turbo spoolup and still retain more on top than the 272's.

 

depends on how high your rev limits will be set...the 272s and 280s are a peak power item...they wont have full potential till after about 7500 rpm...they are top end. Staggering a 264/272 may work for you better however. i can tell you for a fact im going to be putting down better than 450 on a mustang dyno on 93+alky with my 264s... (and a 3076r calm down guys) but my car will spool much quicker than any 35r you see around and your 272s without utilizing thier true potential- you'll eat through gas anyway. 280s are outof the question unless youre going for a strickly drag car, or track i suppose if your driving style and car set-up is for high-revs. stick with 264s or at least do a fair share of research 1st.

 

wont have full potential until after 7500? i dont think so. i have 272/272 and i have significantly increased pull in from 4000 rpm up in all gears.... they are very useable IMO, i did lose some low end but it is hardly discernable.

 

Getting Tuned with 280's on a flash is extremely hard. Coming From Martin at AMS because I was looking to upgrade me HKS 272's and he flat out told me that it's going to be very hard on a flash. No offense but Martin is one of the best in the country at tuning.

Depending what your goals are I would stick with either the 264/272 combo or the Hks 272's. They are proven and perform very well. As far as them not reaching full potential until after 7500 that is nutz!! Redline in most cars is 8k unless you have a built motor that just would not make sense.

Do a bit of research or any questions call one of the tuners, AMS, Turbo trix any of those guys will be better at helping you that all of our own opinions. Just make sure you buy a set of ARP headstuds while doing the cams. If you are sticking with a flash, I would run the 272's.

Just me .02 cents

 

its nuts because youve never had your car to that point am i right? I thought the same thing when i first heard it too. imagine the power youre making/losing all over the powerband...you know for a fact its got to be somewhere...and it is; all top end. im not denying they are a great upgrade for certain applications, but we're talking about a street machine...plus the 264's will be more beneficial to a mid-range turbo, with the proper supporting mods youre looking at spooling where stock spools for a 3071 or a 3076 well maybe not the 3076...but damn close.
