Re: EF-1 (EK-TUNED)
you reall didn't find any useful info on EF-1? hmmm... well what do you want to know. I'm sure that Rocket would be able to tell you everything you'd ever want to know and then some. I know a little and might be able to help.

Re: EF-1 (EK-TUNED)
i'm buying cams pretty soon and TODA's seem like a good reliable choice, but if these EF-1's are better, i'll go with those, i just need some info on them from people that have used them or currently using them...
here are my plans....

Re: EF-1 (EK-TUNED)
Agreed. I think it would be wise for sales reasons if EF-1 could get some dyno numbers, comparing various EF-1 cams to the popular alternatives, Toda B's, Jun III's, Skunk2 Stage1's, CTR's, etc. I too would consider these cams in the near future, but I can't find any difinitive dyno numbers or proof that they are comperable or superior.

Re: EF-1 (Unsung EM1)
The "Jun Killers" are pretty big. Wouldn't you have to have EVEN higher compression to utilize those to their potential? Or with the same compression, it would still yield more power then jun 3's?

Unless the comparison is done in the exact same car with the exact same set-up and tuned by the exact same shop the numbers would be misleading and possibly biased depending on who wanted what cam to SEEM like the better alternative.

agreed... most of the dyno plots I've seen on the net are from "simiar" set up cars... but even with the same car you'd still have issues such as heat, humidity, etc... I don't think that there is really ever a 100% accurate way to compare parts.

TODA and JUN's are not with out there problems. Toda A, B, C profiles are very harsh on the valve train. The ef-1 profiles are decently smooth for race profiles and can be taken to high rpms without causing most aftermarket springs to bounce.
However the availability of our cams is excruciately slow. If you want a non ef-1 cam that is a really good cam and is available PM and I'll tell what cam that is.

Yeah, I am going to build myself a 2L BVTEC test mule and test all cams I can get my hands on. Everyting from m20 to m25's and all competitors.
I need help finding a EF hatch as my test mule.

Re: EF-1 (Art701)
a myth? did u not see the dyno vs jun 3's? what sort of evidence do you need?
they're hell of a lot cheaper then those other "jdm" cams
we'll be dyno'ing m22's in about a months time on a stock ls vtec, i'll post up the results as soon as we get them
