Thread: Great Thread For Kelford 184c Users To Talk

Which is why I thought that a 20V/184c would be ideal since the 20V low & the 184c low may make the same power. Just ask Kelford to make the combo or have the 184c low cams with similar duration and idle quality as the 20V lows. Since the 184cs are supposedly a race cam the use of cam gears by Cory may be the temporary solution for the idle for now. Don't know if additional timing down low would have helped the 20V lows like it helped the 184c lows, torque gains were impressive. Then again we'll find out soon through SR20GtiR's test results. Curious how much larger the duration of the 184c lows are compared to the 20v lows, if at all. Since this all pertains to idle just throwing it out there, kinda like S4 idle lopiness. Thoughts?

You really dont understand.

I am the biggest fan of 20V L lobes, I cam up with the concept 5 years ago of running these things down low.

Changing the low lobes is not the problem that we might be having If the both are the same size and or make the same WHP. The problem is the low lobes are not centered properly on the kelfords. If you take any cam and move them to far of the center lines that they were designed for you will get a bad idle.

SR20GtiR understands what I am saying and that is why he is going to run the 20V Ls to see the power curve vs the Kelford Ls.

has any one actuly 100% degreed the cam per kelford spec's or are we tossing them in and just playing with gear settings? i know they share the same base circles but if the other specs are off like lash etc that might cause some issues as well.

i would love to test these cams for my motor...

Yeah ppl have degreed them and run them on kelfords suggested centerlines... results are about the same as mine. Very simmilar gains and curve. The thing about the suggested centerlines is that they suggest both 102/102 aswell as 104/106. But iv heard ppl having great results with 100/98. So I think just playing with gears works just aswell. The base circles are ground very well and lash is still good.

These were based on the sr16 cam and them the intake was advanced slightly and ex retarded a bit...

well that narrows that part out lol.

I do understand, the low lobes are not centered properly and that alone can be the cause of the bad idle. Doesn't make sense for Kelford to muff the centerlines on the low cams on their remake of these and risk the centerlines on the high cams being off also. Thought they resolved those issues with the v2 remakes.

We are all, human and we all make mistakes. The V1 cams did not do anthing special, so some mistakes were made. The V2s are doing great things. It might have just been and oversight or a small mistake. I am not putting them down as I will be getting a set, all I am trying to figure out is whats up. When SR20GTi-R finishes hi dyno runs we will know.

Does cams peak at what rpm an hold up too what rpm

This question is hard to answer because of size of motor.

On Cory's 92mm piston x 86 mm crank 2.3L, peak WHP is 8500 and holds to 9500.

On a 86mm x 86mm 2L motor, this will be much higher.

On a 92mm piston x 92mm crank 2.45L motor, the larger crank will cause peak WHP to be much lower. You are looking at something in the 8000 and holding to 9000 area.


For an example. Corys N1 cam 2L peaked at 8600 RPM, and his N1 cam 2.3L motor peaked at 8000 RPMs. You can clearly see the bigger motor having a lower peak RPM. This is more exaggerated with a larger crank.
