Cam test: I will be dyno test: delta hks 272, delta K272 and BC 272 cams!!!!

[VETTE_50_TH]

VETTE Tsimage is right. You want 212-213 duration @ .05" lift cams like the fp2s, hks 272s, bc 272s, or comp 101200s, or similar. 226 duration kelford 272s are way more than you want. Especially with the td05h hotside.

True. But again, are they streetable. I dont want to buy cams twice. So if i can run the kelfords, instead of buying two sets of cams, thats what i want to do. Esp if i go to a larger frame next year, such as a hx35 or a fp3052/3065.

Dsm-onster,

Did you get the PM i sent you a few days ago about cam selection?

What is your definition of "streetable" The Kelford 272s are indeed streetable but for your specified turbo, smaller cams will net you better gains. If you aren't revving over 9K smaller cams are far more "streetable" options. However, for the turbos you mentioned such as the HX35 etc, a cam the size of a Kelly 272 will better flatten your power curve, however this setup is far less "streetable".. There are pros and cons to everything.

 

[VETTE_50_TH]

Are you saying an hx35 isnt streetable? I bet there are a bunch of people that will beg to differ.

 

[BigBeans]

He's talking about cam streetability, not turbo streetability.

 

[VETTE_50_TH]

Well, either way, i guess ill just wait til the dyno sheet comes out. I want to see how quick his spool is hindered and what kind of more power he makes compared.

 

[Bender]

Hx35 will perform the same as your 20g. That would be a stupid upgrade. And yes, the kelfords would still be too much for a fp3065. I would get them for something in the Gt35-37 range.

Hmm. Ok. Well, thats good to know. Thank you.

Stop bickering with me, you are making yourself look quite foolish. Try learning something instead of acting immature. You ask me not to talk down to you, but ill admit you're making it hard.

On a side note, a HX35 will most definitely outperform a bastard tod05 20g. It really isn't close.. Look at the housings alone and lets use some common sense here. Sticking with the billet 7 blade wheel and a bolt on setup with Kelfords would be quite the potent setup but would be furthered by going full T3. (Cmon, we are talking abotu a turbo that puts out, near 35r power and is the same size as my 35r was with the larger S housing)

Not only will it make more power, but it will do it a lot easier. IF you are looking for something more laggy to improve millage then a T3 HX35 7 blade setup, full T3, external gated with Kelford 272s would be perfect and a track beast at that.

Then again, as I mentioned before, it'd be easy to find out about if you used the search feature.

Ok man. Whatever. You still have stated nothing that i dont know. And i have a TD05H 20g. Not a bastard. I realize a Standard 20g will not perform at the same levels of a hx35. I have read all the compressor maps. I know what my 20g will max too as well as the hx35.

I was looking for real world experience with the Kelford regrinds and i have only gotten one real answer. Please learn to respond to the questions rather than your opinions of what you think i should and shouldnt do. Thanks.

Post your paypal ID. I'm sure people will help donate a few bucks here or there. Every little bit helps.

Why thanks fellas much appreciated. My paypal Id is [email protected] I have a dyno session scheduled for tommorrow with these Delta K272's! Hey fellas please pm each other if you may have a problem with a post that someone make here. I really want to keep the thread open until I have tested all the cams

Did you have to shim these? Are you buying these cams or are they providing them to you for cheap? I am torn right now between getting the Delta HKS 272 or the Delta K272's. The HKS are 250 where as the Delta K272's are 350 regrinded.

Not sure which to do. I guess itll come down to the dyno and what happens. Suggestions?

No I didn't have to shim the the Delta K272's because they are cut from a brandnew billet core. They are not a regrinded camshaft. These cams are really aggressive almost too aggressive for my setup being that the power really kicks 6000 to my redline which is 8000rpm combine this with the bw259 the stock intake manifold may have a problem letting the air pass without restriction dyno will let us know.

Are you kidding me? The bolt on hx35 comes in what? A .55 A/R housing? The turbo is comparable to a 50 trim as is, then you are going to choke it out in that puny housing?

The 20g's have been proven to 119 mph trap speeds, and the HX35 is right up there. Actually, most of the Hx35's are in the 110-115 range. It is a stupid upgrade to buy a whole new turbo for what? 1-2 lb's of air per minute.

The only way it would even be thinkable was so you can upgrade to a T3 frame, with the manifold, then a week later get a bigger T3 turbo.

A sensible upgrade would be the 20g to an HX40.

 

[dsm-onster]

The 50-trim compressor flows 49lb/min. The 20g compressor flows 48lb/min. Even the lower flowing hx35 flows 53lb/min. That's a 5lb/min difference; 60+whp. And the hx35 has been proven to 126ish with even the stock intake and exhaust manifold. In fact only one of the hx35 results in the holset results thread show it to be under 119mph, to which you say the 20g is proven (126, 122, 119, 115). And the bolton hx35 is proven twice to be 500whp turbos with lower reading mustang dynos. Up through this level of performance 1mph is a big deal, especially with the stock manifolds. There is much more to a hotside than the turbine housing. In the hotside, not only is the turbine wheel MUCH larger than the td06h turbine wheel; but also the .55 a/r turbine housing has a MUCH larger critical area, and a MUCH better shaped volute (centered and tear shaped vs offcentered) than the td06h 20g.

With that said I still don't feel the kelfords are a good upgrade for an hx35 build unless you want to max it out completely in the bolton housing. If so, go for it. Also if you plan on running the larger stock hotside or the bep t3 .70 a/r hot side and especially something like the 60 lb/min 7 blade hx35 compressor, then yea definately look at the kelford 272s. . . You'll get no benefit going to the kelford 272s, because they make power through raising the rpm range of peak torque-- higher duration. You need to modify the nature of the 4g63 intake flow, IOW, running a SMIM, like the ams tests provide to get the benefits of such high duration that kelfords use to make those better results; and run a turbo large enough to merrit such an upgrade. So IF your build doesn't include a SMIM, you're really wasting your time with huge 226 duration cams like the kelford 272s. Especially since hks 272s, and others like fp2s having the same effective duration, resonate at the 2nd harmonic with the 1g intake manifold runner length right at 7000rpms. . .

Thanks matt for this. What you are suggesting is all in the works. Such as the SMIM and going to a fp30 style turbine or maybe a t3 .70 Ar. It all depends. I just want to see how it performs on the dyno. So that if his 4-8k rpm range is improved, itll be a worthwhile upgrade. If its from say 5-8 or even later, then i wont go for them. Thank you.

Has anyone heard or know the validity that FFWD cams (DKS, etc) are actually Delta that have been rebranded and marked up?

This is news to me, I was reading a thread about it on link and someone had some claims in regards to it.. if you have access to it..

ECMTuning User Support Forums

I know the FFWD DKS cams have been around for quite sometime with no real bad results..

Maybe jon from delta will chim in and set this matter straight I have wondered this myself

 

[Delta Cam]

red turbo you have PM

 

[VETTE_50_TH]

Please send me one too.

 

[keltalon]

Finally dyno tested the Delta K272's. And all I have to say is wow! These bad boys put down 536hp and 499tq @ 31psi. The stock intake is really hitting its limit at around 6500rpm. Posted is a dyno sheet and log for observation. Cam gear settings were as follow intake settings 0 degrees and exhaust 8 degrees advance. This dyno sheet is a comparison of theDelta K272's vs the bc 272s

the dyno sheet on the bottom is the hks 264s vs delta kelford 272sgrind

 

[JEFFREYCASTGSX]

Kelford regrinds are next on my list.

 

[Killa_dsm]

They are not regrinds.

 

[JEFFREYCASTGSX]

They are not regrinds.

Deltas kelford spec GRINDS then.

 

[Rob10_99]

Yeah that stock intake totally dies at 6.5k,

 

[TSIfreek]

Thanks for the fast reply on the test. I noticed you only reved the motor to 7k according to the dsm link graph. Not that it would have mattered. What kind of vacume are you seeing with the kelfords??

 

[RedTurboEclipse]

is the last test the delta hks 272 grinds?
