The settings for the jun 3 was 0 intake cam and +1 exhaust cam. 47 psi @ idle, 17 degree timing (gained an instant 10 hp between 14 to 17 degree spark timing)
my setup that is relevant to making power is..

b20/vtec, Endyn RW high compression pistons, 3 layer b20 gasket, endyn ported head, 310 injectors, 255 lb/hr high psi walbro fuel pump, eagle rods, 9 lb flywheel, msd 6al, jdm dc header, endyn ported ITR intake manifold, jg 64mm tb, homemade 3" cai and of course, jun3 cams, chipped P28 with a stock jdm b16a program w/ raised rev limit.

The dynoes were made on the same motor roughly 5000 miles apart. I compared the jun3 cams vs the 403 and the advertised lift of the 403 were 12.5 vs jun3 12mm. I can tell you with certainty that there is no way that the 403 has more lift than the jun3, maybe possibly that they both have 12mm lift but if anything the jun3 has more lift no doubt. I believe the reason why I made more power with the 402 is because I had the old-style 63402. These 402 had a 12.5 mm lift but recalled them because of a few cams breaking due to the excessive lift. That is the only reason why I think I made more power with the 402 because the old-style 402 actually had a bigger profile than the 403. Now crower has reduced the lift of the 402 to 12mm to be safe. Somebody correct me if Im wrong.

This was not a perfect test as the 402 could have been tuned a little better (but would not have gained top end) and the 403 were tuned with an ls distributor that could only retard 19 degrees when intake cam is +4. Also the jun3 was tuned with an open header and without a wideband o2 sensor because the o2 sensor just couldnt heat up with an open header to read anything.
I still like the 403 and I believe that they would actually be good on a stock valvetrain and if anybody is interested, I'm selling them for 550 shipped. email mingchi69@hotmail.com if interested.
Also notice the flat torque curve of the jun3. If it was plotted on the same scale as the hp curve which was 0-250, that torque curve would almost be flat. Also my peak of 225.9 with the jun3 is actually prob 224. The ecu im running is weird as in it has different rev limits whenever it feels like it. sometimes the rev limit is at 9000 and other time it is at 8700. I believe I would make more power if i had a higher redline and better headers. This motor has roughly 15000 abused miles. I have zinged it to 9000 prob a gazillion times. Just goes to show that power and reliability can go hand in hand if the motor is built right.

 

where are the pics?

 

woops.. here it is

it says page unavailiable

 

dewd no offense but it looks like with the JUN you were using an open header, while with the Crowers you had your full exhaust on. If this is so then the comparison is not fair. If I am wrong and you used an open header on all three then

I am doing something similar, with my B20. Except I will use Hondata, ITR cams, B16 head, JE pistons and either Eagle or Probe Industry rods(same price), I will be happy with 205whp

 

Dewd 146 torque seems really low

 

jun3 looks amazing

 

The Crowers don't seem to be any better than CTRs. Oh well. Although...the issue with the distributor and the 403's probably killed a good bit of power. Great, I have still yet to see a good dyno test of Crowers.

If I ever got cams I'd get a JUN 2 intake and CTR exhaust.

I said it was not a perfect comparison, but the main idea is there. Besides, I dont really think an open header did that much anyways. Yea the torque is prob lower with an open header. Also, I had a lot better average torque than most people. compare my torque curve to that of my 402 which I peaked 151. No comparison, the jun3 torque curve is much better. if you were to take the area under the curve of the jun3 vs the 402, there is no doubt that the jun3 will be soo much more. Also notice the nice fat torque curve during vtec and it does not die down as fast. It might not peak as high but, average torque is what I would rather have. The only reason I dynoed open header was because my header collector was 2.5" while my exhuast piping was only 2.375". You dont want to go from big to small.

just delete http:// and it works..

 

Bringing this back from the dead because his cars on ebay.

Where did you get the car tuned? 235 is awesome

 

your not doing justice to that setup with that ECU program, i bet with the right fuel and ignition tuning you could easily gain 10=15 more hp. I know because I was running JUN III on 12:1 compression and swticed out my old ECU to a hondata with a SGT tuned jun III map, I cant get any traction now

 

your motor is sick
