Well since we're doing the header test why not a cam test. I figure most peeps would be interested seeing how thats usually the next step after i/h/e.

otherwise stock car with only cams and gears. what ya think?

 

I think in order to see how well a camshaft perform, tuning will be the most important factor of it. And it will be difficult to do, since it may actually take up to one day on a dyno to tune for a set of cams. And then even after you tune it to the best you can, people will then you should use this I/H/E combo for this cams and other combo for the other cams. And then there is the ECU factor, there is no one ecu that will suit best for all the cams, expect for the programmable one like the Power FC or Hondata. But then I wonder how long would it take to tune these on a dyno.

Afterall, with all the money and time that possibly require, I don't think it is possible to do.

 

A real good cam test is going to cost in excess of 20k easy, and at least 2 weeks of solid 9-5 work, with at least 100 hours of labor.

Ill do it if everyone who has a particular brand "loans" me a set of each, and I get like 5k to close my shop for 2 weeks just doing it non-stop.

I will put in Toda Valvetrain, since that valvetrain I believe will handle any cam you can buy for a VTEC head.

And then, after I test for 2 weeks straight, a bunch of people are going to complain I used the wrong header, or the motor wasn't enough compression, or the cam gears were wrong, or whatever.

And the test will absolutely **** OFF alot of people, and companies...

As will the header test, which is also not a good idea. After that test, people are going to be PISSED and companies even madder.

I have a *unofficial* test going right now.

I'm just doing it for my own knowledge.
I'll be posting results very soon, but I'm not gonna put up with any smart-*** remarks or wise-cracks. I'm gonna be posting this as a "look at this and make your own judgement on it" kinda thing.

B18C5 with a ported head by Topspeed Performance
.5mm over stainless valves, ITR outers, Portflow inners
Endyn 81.5mm pistons, 12.2:1 compression
OBD-1 conversion w/ Skunk2 program
JDM Mugen stainless 4-1
Tanabe Hyper Medallion exhaust
Stock ITR intake pipe w/ Comptech foam filter

So far, I have dyno sheets of the following...

CTR intake/ITR exhaust
Toda Spec A's
Toda Spec B's

Working on the following in the next 2 weeks...

JUN Stage III
JUN Stage II
JUN II intake cam/ITR exhaust cam


Later..

 

Mike, I would be really interested in your results regardless of how they are interpreted. That is interesting that you are contemplating testing Jun2 intake cam with the ITR exhaust cam. I have the Jun2 cams on my car but I have been thinking of trying out a bigger exhaust cam, you are doing the reverse, going to a smaller exhaust cam , interesting. How about testing the Jun2 intake cam with a bigger exhaust cam while you are at it ? , perhaps along the line of the Toda A exhaust cam or Jun3 exhaust cam. that would be interesting as well. keep us posted , look forward to the info.

JSIR.

In looking at the Honda motor...the cams in the exhuast do not mean much compared to the intake cam.

The intake cam is where the power is made mainly.

Notice JUN 3's.

The intake cam is 12MM lift, but exhuast is ONLY 11.5 MM. Thats tiny compared to a Toda Spec C exhuast cam, or B.

I have run stock exhuast cams with a big intake cam, and the results will open eyes.

Running huge exhuast cams, is pretty much a total waste of money and time in most applications. THe motor breaths tons with even a small exhuast cam. And with cam gears, you can take a small cam, and dramatically increase its breathing.

You can also do the same thing with different valve adjustment heights.

Watch Mike's tests...

I suggested that he took a JUN cam, and use a stock Honda exhuast cam...

and watch...its going to dominate the Toda cams. And the mid range is going to be strong.

Good job Mike. I wish we lived closer, I would throw some more cams in there.

Skunk 2 cams are really good for the money also. Similar results to JUN 2's.

Yea we'll see Jeff.

So far, I have seen good results from the Skunk cams. Stock GSR bottom end with a ported head, 10.5:1 compression(milled 18 thou), JDM 4-1 and skunk cams.
181 and 131 at the wheels. sick.

 

Mike: could you happen to post what power you made with the CTR cams?
