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

[Artago]

A nice (picture oriented) summary would be great!

Thanks,

Tom

Keltalon, thanks for your contributions.

I don't suppose i can talk you into testing the HKS 264/272 combo, is there?

I'll contribute $30 towards the dyno time.

 

[keltalon]

I would have posted these sooner but I just got them in a email from the dyno lab. His network was down and could not send them redlines hks 264s blue line Bc 272s

Here is the 31psi run

 

[dsm-onster]

Interestingly, at 4500rpms you gained airflow going from 31-33psi, but you lost torque and horsepower. Timing was the same. Fuel settings weren't altered.

 

[keltalon]

I got you. Heres my prediction from highest to lowest Kelford>>>HKS 272>>>>HKS264=BC272.

Well the Bc out performed the the hks 264. Bc sent me a set of 280s to throw into the mix. So know I another set of cams to test before my car gets back to normal. I don't mind for I myself have always wondered about different cams and their impact on power I think I just might look into a smim for the testing of the BC 280s and the delta Delta K272's. I need you guys input

Maybe let see how tired I am after the testing. I tell you what I really would like to test is some manifolds!

So, the BC's and the HKS' were both installed straight up, no degreeing, right?

Dang, .

well the hks 264s was installed straight up the bc 272 was retarded on the intake about 5 degrees and the exhaust was advanced about 5 degrees. As far as actually degreeing the bc's I didn't but just played with different settings until I acheived a hp that I was comfortable with on the streets.

It should be noted how the cams were installed per how they were set up on each cam gear. This gives us a good idea were to start with going to the dyno. Cams set up on my engine might not be the exact same per the cam gear marks on your engine but they should be close.

 

[Bender]

Well everyone's setup is different per many reasons stated earlier in this thread. I think a note saying the cams were degreed to his setup would suffice.

 

[keltalon]

Well I have installed the Delta K272's. I am very impressed with the quality of these cam shafts. You can tell that they are a new grind and not a regrind Vacuum is around 13hg. I have also played around with various cam settings and have decided to leave them as follows: Intake 0 and Exhaust 8 advance I will change them more once I hit the dyno. The car has a slight lope to it even with the exhaust cam advanced 8 degrees nontheless she pulls very hard up top. A little power is lost down low but makes it up on the top. It must me noted these are not small cams!! I repeat they are monsterous I will be getting to the dyno no later than wendsday to see what they will do Like all large camshaft fuel setting at idle had to be adjusted. Stay tuned

 

[welfle18]

When you say your fuel settings at idle are you talking like the dead time and what have you by dailing in your LTFT and STFT? Just curious because I am about to install a set of these and to have somewhat of a base to know where to start is always good to know.

One thing that is bothering me about the dyno comparisons and your logs. . .

The hks 264s are making 10whp less but with less timing and higher IAT. The airflow is HIGHER everywhere in the rpm range with the hks 264s at the same boost. 20 degrees different IAT and 1-2 more degrees of timing certainly makes up for the 10whp difference.

Look at the timing settings I used the hks 264 dsmlink settings on the bc run. hks cams were tuned the bc was not. also look at the hks 264 boost estimate its about 3psi higher than the bc boost estimate. I think i made a mistake in saying the hks 264 run was at 31psi when I think it was more like 33psi. So if you really want to compared apples to apples then the 529hp logs is the one you should be comparing. So the bc really made 10 more hp than the hks with 2psi less boost Thanks for helping me to make the correction!

I had to richen the idle setting via airflow sliders to get the car to stay running.

 

[dsm-onster]

AHA! I see now I forgot that you weren't tuned with the bc272s too.

BC272s are definately a nice step up from hks 264s.

 

[keltalon]

I will fine tune the cams that I will end up using. The dyno time is kicking me in the rear cost wise. and still have 3 more sets of cams to test. Thanks for ovservation though

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

[fergulus]

I would donate, especially to see how the kelfords do with a proper tune versus the others.

 

[TSIMonsteR]

same. I'd gift a few bucks over to you.

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 Kelford 272. The HKS are 250 where as the Kelfords are 350 regrinded.

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

Do yourself a favor and get the HKS 272s, you aren't ready for Kelford 272s.. Do a search before you post up questions like that. The only similarities the Kelllys have to the HK$ versions is the number 272s. The Kellys are twice the size, require special valve train and sound like a tractor.

Please do not talk down to me, thank you. I know what Kelfords and have done the research. This question really wasnt directed to you. I will be running beehives.

So, could you OP please give opinion on the Kelfords for the street? I am kind of fed up with being in boost at 3 grand. Its killing my gas mileage. When does the kelfords really open up? Are they streetable? Do they hurt your performance that much more in the lower rpms compared to the HKS?

You aren't being talked down to, the fact of the matter is that the comparison of the 2 isn't tangible.. If you are looking for cams to push your power band higher up in the rpm range the obviously the bigger cams will do so, which in turn is a no brainier.

A more important piece of the puzzle is, what turbo do you plan on running and what are your ultimate/final goals. That will determine which cam is truly better for you.

 

[VETTE_50_TH]

TD05H 20g. I more looking for a cam that will do really well in the mids and highs. And allow the turbo to breath in the upper rpm. Im not really looking for a higher rpm range, just more power throughout the 4-8k range.

 

[dsm-onster]

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.
