The other day, Saturday, myself and little brother trundled out to what appears to be the only accurate local dyno.

It was a cool, rainy day. The fella that was running the dyno was having huge problems with the printer software, and unfortunately, we did not get a chance to tune the cams/timing. We did, however, get enough runs in to accurately dial in a nice flat fuel curve at optimum mixture, with a wide band 02 sensor. Yes, I know the proper word, but I have problems saying it, let alone typing it.

It was interesting to watch the characteristics of the car (engine) change with increases in fuel pressure, and fine tuning on the VAFC. But the really intersting stuff (cam tuning) will have to wait until the next time. It took about 2 hours to get the fuel tuned properly, and by that time we had to bugger off.

We ended up with a best of 188.9@8300rpm, and torque was at 128, somewhere a little lower on the rev scale; cams set at 0 degrees, both intake and exhaust. What I found interesting was that my peak power was relatively low at only 8300rpm. That suggests to me that my goal of 200whp is actually realistic, considering I should be able to see my peak move to over 9000rpm with the Spec B's.

All told, I was pretty happy with that, and it gave me hope that I should be able to realize my power goals.

My thanks go out to Little Bro for the time he took to sort the fuel mess out, Lip, who gave me somewhere to start, and to A&J Racing for building what is becoming one kick ***, daily driven motor.

One other question: I noticed that I could only get the VAFC to go to 9000rpm on the fuel scale. However, on the graph scale, it would go to 10000. Is there way to bump the fuel scale up another 500rpm?

I would post the graph, but I have no idea how to do it anymore. If anyone wants to see it, and can post it, let me know.

 

nice going

once you hit 9k....whatever percent increase in fuel you made at 9k would be the same at 10k.

the fields unit only goes to 8k which is one of the reasons i prefered the vafc over it

 

Email it to me and I can post and Host it

 

Cool!

What's your setup?

Thanks,

Is that the infamous Technik printer? I've been telling Ross to fix that damn thing since February. Next time I'm bringing a gun.

Cam timing should yield a lot more power given you're running higher compression. Are you still running that crazy side pipe exhaust?? don't you get tickets for that?

 

I do not know what kind of printer it was, but it sure was irritating; really took the steam out of what was going on.

No, the side pipe is gone.... for now.

I see on another thread that someone else posted similar results with only one major difference: I do not have a Hytech Exhaust. I thought the Hytech was good for 20 or so bolt on Hp.

 

I will post all my dyno slips soon. The one I posted earlier was indeed wrong and did not include the Mugen ECU (i made closer to 185 i think). hopefully it won't take TOO long to break in the new rings and i will be able to post my results with higher compression.....that is if the printer is working. A&J said that they could get Yoshio to fly in to tune my car when it is ready - I think I will take them up on that...that is if I can get some dyno time.

Have you noticed any difference with the CTR pistons? power? torque? pinging?

 

i'm not sure when people started making assumptions that whatever you do to your motor...you can add 20hp to your plot once you get a different header. Thats like the people that add thier hp by mod claims and saying thats what power they are making without ever even seeing a dyno machine in person. I think the point is....you can make MORE power with it then your current header since your current header thats not stock is more then likely making a few hp already.

enough of the bashing folks
