What Delta cams? 264/272 or 272/272?

[MattratfTSI]

Im sending my cams in for a regrind at Delta cams. I just cant decide if I want 264/272 or 272/272. Actually, I dont know what the performace differance would be. They will be in a stock head aside from 3g lifters. Not reving passed
7k. So my question is, what's the performance difference between 262 intake and 272 exhaust, or both 272s? And what would you suggest to a fairly stock motor? thanks alot.

I suggest the 264/272. Just make sure you tell those guys which profile you want to go with which cam. They did mine a while ago and I ended up with 272 Intake/264 Exhaust.

what turbo? had the HKS 264/272 on my 1st gen with a 60-1 but wanted more out of them cams it was a small regret.. FPX2 cams for a small turbo would be great though.

that sucks so bad..

its funny you responded to this thread... I just watched your video on youtube. The red gst sounded bad ass with the wrong cams haha. I think im going with 264 intake 272 exhaust from Delta. I hope they dont screw mine up. I wil make sure to write exactly what I want when I send the cams in. how long did they take to get back to you?

 

[jstgon]

Would like to know how long as well.

I got my cams from them.I got them very fast.Then I sent mine to them as cores.I got 272/272 and I love them.They pull hard in the upper rpm's running 20psi.They sound awsome too.
I got my cams in 2days I think But I live 1 state over

 

[turboking15]

What turbo are you running? Another thing to take into consideration is where do you plan to go with the car? If you plan on going farther with the car than where you are now why not get the 272's? They will be able to hold there own with some pretty big flowing turbos all the way down to a 16g. Personally i would get the 272's and not have to buy new cams for a while.

 

[jjrock5]

IIRC it took like a week for them to get the cams, they ground them in one day, and it took another week for me to get them. I do live in Connecticut and they are located in Washington state...

Let me clear up the 'error' that was made by Delta. I told them I wanted some 4g63 cams done, they said theyve done plenty in the past. I told them I wanted to have the 264/272 combo but never really understood which cam had what profile (I should've researched) so I asked them to grind the combo in the typical way that most DSM ppl get them ground. And everybody know it's 264 I/272 E.

I get the cams back and look at the cam card to find out they had done it the other way. I call them back and they tell me that this is the way EVERYBODY has had it done... but offer to regrind a second set if I cover for shipping and send them another set of cores. I never really got to it since I sold the car.

After researching, ppl had told me that 272 I/264 E had been done years back and it wasnt "wrong" but just not the typical way ppl nowadays do it.

Delta really is a good company and the ppl there are very friendly and can really inform you before buying. I recommend them, just tell them exactly what you want.

I would do a 272/272 combo for anything with a 16g hotside or bigger. That includes a 14b with a 7cm^2 turbine housing that turns it into a 16g hotside. It's worth it. The increased overlap really helps spool and midrange. So you don't feel a drop in VE that you would normally feel with increased duration. Fp2 fp2X and hks 272s (delta regrinds are like hks) all have a sizable increase in overlap. I loved my fp2X cams with my small 16g. It pulled great from 3K up. REALLY hit hard at 3500rpms (16g hit). The delta 272 regrinds are doing really well on my other awd 93 car. This has a 14b with an ebay 16g turbo 7cm^2 turbine housing. VERY much fun. I never noticed a drop in spool speed. And based on the hertz count, I GAINED air from 3700rpm on. That's an INCREASE in midrange. Ken of Delta is areally good guy. He's been into the scoobie scene recently. Get him some more DSM orders

 

[MattratfTSI]

ok thanks for the feedback guys. I have a 14b with stock hotside at the moment but ill probably go bigger soon. I still dont really understand what the obvious differences are between the 264/272 grind and 272/272. Are we talking different power bands with a different intake cam or what? different idle quality? It sounds like 272s are good for 16g and bigger... I just want something that will pull harder in mid range rpm on the stock 14b or 16g and have a mean lopy idle. so now im torn again!!! 264/272 or 272/272!!!

 

[jrohner]

The 272's are not very aggressive actually, so I would never go less. It would be like doing half an upgrade.

 

[dsm-onster]

Yo will NOT stick with the stock 14b hotside for long. . . Either new turbo or bigger turbine housing. Any cam upgrade will only exacerbate the situation

 

[95gst16g]

I think you should just do 272's.The only reason I see doing 264/272 is if you DONT like the lope on idle.You really dont notice the difference in power in the lower rpm's too much.The 272's will sound more aggresive,if thats what your into....And I dont care I love the lope.

 

[MattratfTSI]

ok thanks. Ill run with 272/272 as it seems there wont be much of a difference or reason if I do a 264 intake cam. And to jjrock5, how does payment work with these guys? When I called they just said send your cams in with a note with your info on it. The guy said nothing about payment. Do they do paypal or what?

 

[Delta Cam]

This has been a "hot" topic up for discussion for many years.
272/264 exhaust camshaft smaller in profile, to keep cylinder pressures up and benefit from the forced intake.

264/272 exhaust camshaft larger to spool the turbo faster.....

272/272 damn bigger cams move more air right.

I have heard all these arguments over the years, and yet nobody has run side by side dyno pulls to find out which actual combo works the best !

If anyone has the shop to swap cams and do dyno pulls back to back please PM me or text directly (253) 241-7447
My Mitsu is a 92 na car if I had a turbo car I would have posted the #'s
Not selling anything nor am I promoting our product, I just want numbers !

They are really great on the phone. I send my cams in, called the day they got them (checked tracking info) and they said we just got them give up 2 days we'll call you.

They called me back, I paid over the phone and I recived my cams in FL with a week and 1 day turn around. Product is really really nice, below are pictures taken with my camera phone but they look great.

(REMEMBER TO CLEAN them well as they get cardboard and paper scraps on them)

Great work, any thing you see on the as dirt is from the shipping box, it wiped right off.

Payment was the same way for me ^

 

[JayRolla]

Delta someone has done a side by side of the 264/264, 264/272, and 272/272 on a 16g powered car. I cant find the old link but I do remember the 16g benefited best from the 264/272. It made almost 15lb tq over the 272/272 if I remember right. The 272 barely gained a little power up top but lost so much tq downlow it was not worth it. Still I'm about to order a set of straight 272's since I know I will upgrade the turbo someday.

[hurricanecris24]

Good to see some numbers on this topic. I'm going for the 264/274 combo

 

[dsm-onster]

HLS 272s are not IDENTICAL to delta 272s, just for reference. That cam test does not include delta cams. A tiny difference makes a huge effect with cam profile characteristics.

 

[Delta Cam]

correct, out test has yet to be run. Aaron has the cams and is awaiting swap dyno time.

 

[nitrokid]

did those cams come with the shims?

 

[Delta Cam]

yes all regrinds come with shims.

 

[BrokenTsi]

Hey DeltaCam, dont you guys make an exact copy of Kelford 272's? My buddy said to call and ask for K272's and you would know what I wanted.

 

[Delta Cam]

yes we offer that profile
