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

[fergulus]

I just want to say thank you for the extensive amount of work you put in to test the standard cams we buy. You definately helped shine the light on many of the questions people have been wondering, especially myself. Your work will no doubt help many people make the right choice for their setup based on your results.

I too would like to commend you for the great work you have done. I hope you will find the time later to summarize your findings in a single document and put it in the Tech Guide section.

Thanks! The only regret I have is I wish I could have finished!

ok well i didnt want to start a new thread about results for delta cams ( 272/272) so i figured this thread would be appropriate to post my results.

to give you guys a little background on my setup with stock cams:car has a 20g ( td05 clippped 20*) and was only able to squeeze out a maximum airflow of 40 lbs/min at 28-29 psi. i could not go any higher than this airflow point no matter how much boost i pushed through the motor. i was told that my stock cams and stock throttle body(2g) was a huge restriction for the motor; resulting in these low airflow readings. i have attached a dsmlink log with my stock cams and stock throttle body ( labeled accordingly)

so, i ordered a pair of delta 272 (in /ex) camshafts and slapped on a 1g throttle body. i was able to extract 41 lbs/min at only 21-22 psi!! huuuge improvement.thats a 15 lb/min increase comparing both logs at 21-22 psi. i couldn't turn the boost up due to the limiting factor of my injector size ( ordered a new set yesterday should be here by friday) i have attached a dsmlink log ( labeled accordingly)


spool time was slower by 400rpm ( comparing logs) and some low end torque was lost but man does the car pull on the top end. idle is moderately to very loopy. vacuum dropped from 20-21 in/hg ( stock cams) to 15-16 in/hg (272's)at 1000rpm.
overall, im very impressed with these cams. obviously all the gained airflow was not soley due to the cams ; throttle body was also added into the equation. but i have been told that a 1g throttle body will only add 1-2 lbs/min at most over stock 2g tb. so i believe the cams were the major contributor to this.

Boosted, Was this the hks replicas or the k272's?

All cams sold! Turbo will be here next week.

glad i purchased the Delta K's off you

Nice review. Do you have cam gears installed? If so you can gain A little of your down low back if you advance ex cam 3 degrees and retard the intake 3 degrees it will still pull amazing up top but will give you a little more vaccuum at idle and a little better gas mileage

unfortunately, i have no cam gears (yet). i wanted to see if these cams were truly "drop in" as rumored. and i believe that these cams can perform up to bar right out of the box. and definitely even more once degreed.

Ive read every page of this thread but I wasn't able to find out on what motor these cams were tested on so was this on a 2.0L, 2.3L or 2.4L?

lil ole 2.0L

Well my new turbo came in this week. My new t3manifold will be here thrusday. This is one of the main reasons I couldn't finish the testing because so much would be changing on my set up as far as the turbo is concerned. The new unit is a comp turbo from the ct3 series. It has a 62mm billet compressor wheel 65mm turbine wheel .63AR exhaust housing triple ceramic ball bearing center section . It is oiled and water cooled and should last a lot longer than the journel bearing bw259. the turbo is rated to flow around 70lbs/min so its should out perform my old bw s259. Here is quote from comp on the new ct3 unit

"Faster boost response
Less friction—ceramic ball bearings

CT3B Ceramic Ball Bearing Turbos
The Comp Turbo CT3B turbocharger is relatively new on the scene, is dynamite in a small package and has a bearing system that utilizes the latest in ball bearing technology. Racing applications need turbochargers that accelerate at the fastest possible rate and the CT3B bearing system allows it to do just that.

The CT3B bearing system is a proprietary design that is unique in the industry. It utilizes full compliment, angular contact ball bearings with ceramic balls. Compared with steel balls, ceramic balls in ball bearings have a number of advantages. Bearing service life is two to five times longer.

They run at lower operating temperatures and allow running speeds to be as much as 50% higher. The surface finish of ceramic balls is almost smooth, producing lower friction losses and lower vibration levels.

There is less heat buildup during high speed operation, they exhibit reduced ball skidding and have a longer fatigue life. All these characteristics make ceramic ball bearings ideal for use in turbochargers where they must operate at very high speeds and survive in a high temperature environment.

The Full compliment bearings do now use a cage to position the balls and this additional feature, combined with the ceramic material provides a combination that has minimal friction losses.

The mechanical efficiency of the CT3B turbo can approach 99%, and this contributes to rotor acceleration rates that have been shown to be faster than competition

So what about people running 2.3 and 2.4 motors. I still have a smaller turbo, HTA3076R from FP, but im on a 2.4 now. I want the fastest spool and a flat HP and tq curve. Any recommendations?

After waiting 6 day I recieved the wrong manifold therefore had to send it back. In the meantime I ordered the punishment racing cheaper t3 manifold I will be using this one until I can have one custom made. Now i am back waiting on a manifold again should be here tuesday or wednsday. Just want to see what the bc280s will Do

Any updates? It's been a couple days (26 to be exact)...

non yet got to find a little time and money.

 

[burkgonzo]

How about HKS vs FP2s

 

[chanley talon]

I also wanted to say thanks for your hard work. It was very enjoyable to read. I would have liked to seen results with 264/272 hks regrinds but we can't have it all . Good job and i am looking forward to your bc results.

I also want to join in a commend you on a job well done. I am not the most knowledgeable on this subject and must say i have learned alot reading through this. Keep up the good work!

Thanks! I will someday get the bc280s tested I am having to fix a few things and its taking longer than expected

here is my latest delima/update and the main reason why my testing is currently on hold. As soon as I work this issue out I will get back on track.

Awesome thread on cams. I was told the motor I recently purchached has FP 272 cams in it. Im running a evo3 16g. I just wanna get close to 400whp and have a streetable car. The pistons are 10:1 weisco though thank god they arent cp. IM sooooo glad I read this thread. If I won the lottery or something Id send you all the money you needed to finish your testing. Good luck and for the heck of it keep posting your dyno results up here so we all can follow,

After making a few changes to my set up ( fully working cyclone intake manifold, Drop in compression from 9;0 to 1 to 8:5 to 1 Custom Cp slugs and the Comp
CT-3 6265 turbo) Well finally after spending most of the day dialing in the cam gears. The car runs sooth with little to no overlap and with the bc 280 this gives me the best of both worlds smooth idle, quick spooling turbo, and lots of down low to midrange power . The car still pulls hard to 8000rpm. I forgot to mention that the pull in the video was done on 93 octane pump gas with cyclone manifold butterflies open all the time now they are working the way they should after installing a rpm swith from summitt racing. I finally fill her up with a little E85 what a difference. Next will be the fuel pump.

Time to update the mods
Im loving all this info, its like a tuner braingasm
