Just wondering, has anyone ever put in 264 in. and exh...and changed to something else. I think was planning on going 264/264 but i see a lot of people going 264/272, is it yielding that much more power? I think i read buschur uses 264/264 right?

 

do a search and u'll get a ton of comments..

yes, buschur ran 264s when they ran 11.65 with stock turbo and no spray...

unless u plan on doing a huge turbo with a built engine and ported head.. meaning a very high reving engine.. go with 264s and be done with it.. up to 7500rpms there's no hp difference, plus the 264s give better torque from lower rpms all the way to redline.

but again.. just search and get lots of opinions on it.

 

there are lots with 264/264, 264/272 and 272/272. The combo that is right for you depends on what you other current mods (or future mods) might include, and where you want the power band to be.

264/264 works great on a street car, as it maintains alot of low to mid end power.

The 272/272 is geared more towards higher end rpm power. Though its the biggest set HKS offers, these work amazingly on the stock turbo, and are also well suited for larger turbos down the road. These cams, when properly tuned, will support the most peak HP. However, there is no mistaking a 272'd equipped car.....it's got a very noticeable exhaust pulse thats impossible to mask (some like it, others want more stealth, so a matter of personal choice). These cams also require a good tuner to get the idle perfectly set, since they can lope otherwise.

264/272 - a good blend of the 2, hence the popularity of the combo. tne stagered setup offers a good idle with strong mid and top end. Not quite as much peak HP as the 272's, but not far off either. Seems to be a popular choice with customers who use their Evo's for mixed duty (street and track use).

well i think the farthest im gonna go is bushcur stage 4, i dont think i want a bigger turbo at this time and i wont be going past redline.

 

Honestly any of the combos would work best, but I would personally most likely recommend 264/272

 

well ive noticed with the 264 264 buschur doesnt use cam gears i think. would you need cam gears for 264/272 tho?

 

I have the 264 and 272 setup, no camgears and the car pulls hard from low to mid up to redline

You can feel the difference when it boost, the car never stop pulling hard to redline.

 

okay thanks for the info, wasnt sure if they were needed or not.

 

They aren't needed but they can be usefull. I know that seems like a double edge statement but if you want to change your powerband they are very helpfull. You can extract more bottom or topend out of them if you don't want the all around feature. Right now I run the 264in/272ex with -2,-2 and it pulls mad down low and still just as good up top but they can also just confuse the crap out of you. If you want every last cent out of it get them other wise don't bother, right now anyways. Just my experience with them.

 

Good piints - the cam gears can be another very useful tuning tool, but it also requires increased time to get them setup just perfectly. most of the time, our customers opt for cams only, as they provide amazing results on their own. The cam gears, as GTEVO said, are for those looking to extract every last ounce of juice out of their setup.

 

With a set of cam gears and some tuning my Evo gained 18 whp and about 13 torque on a mustang dyno. This was with my Piper cams over a stock 0/0 setting.

I'm sure the numbers are different with the HKS cams, but there should still be some gain.

 

erioshi, do you have the dyno sheet. Im interested in Piper cams myself and would love to see what kind of torque curve they make. Which ones do you run? also what other mods do you have? Any info on these cams would be greatly appreciated.

Thanx

 

Bump, lets see a piper dyno sheet =)

 

I am hearing that combo impairs power versus a 272i/264e due to the engineering o fthe car.

 

The 272/264 works well as well, but shifts the power band downward in the RPM range, whereas the 264/272 shifts it upwards and makes for a bit easier of an idle. All depends on where you want to power band to be. The 264/272 combo has proven itself many many times on the dyno already - as with any of the cam shafts, proper install of the cams and proper tuning is the most important factor
