Compiled Dynos, I was bored

[Claviger]

I paid for their most worked head, and biggest offered cam. Considering the 210 kit is stock pistons and a smaller cam and far less capable head I expected something north of 210 as a minimum. Again I don't fault Carpenter at all at this point, all indications are that they did their part in full and I was let down by my former mechanic.

My bet is the installer moved the exhaust quite retarded in fear of having valves meet pistons again....

If the exhaust cam is retarded the valves will be CLOSER to the piston.

 

[Claviger]

Yeah I have it backwards in my head at the moment thanks.

The timing being way off is the only things I can think of that could cause such a drastic reduction in power, unless the CES exhaust really is ****e for built motors, something I highly doubt given certain bikes I've seen dyno's from coming out of your shop making great power.

First things first, Nels is using the new Winpep 8 software, as of yesterday, and straight from Dynojets own mouth, it reads 5% lower than winpep 7. He verified this by testing two bikes that are like clockwork and put down the same numbers over and over.

Final numbers were 187.8 WHP/154LB-FT, on a winpep 7 Dyno, that's 197whp/162LB-FT.

Correction factor was 0.98, SAE.

There are only two possibilities that can account for this:

1) I was sent the wrong cams, possible but unlikely based on where the torque peak is. The location suggests they are the right profile.

2) The installer has my intake cam rediculously advanced or the exhaust cam is very retarded or some combination of both I/E being way off creating massive overlap.

When testing with no air filters Nels yanked his leg away from the TB mid pull. Afterwards he said it had massive reversion that he could feel on his knee, indicates waaaaaaay to much overlap.

My bet is the installer moved the exhaust quite retarded in fear of having valves meet pistons again....

Looks like I'll be dialing in my own cams after all.

WOW thats way off your correct check the cam timing youll figure it out call BOB tomorrow

I have not personally done any real "built" motors with the CES, although some of my parts have gone into a few guys engines with them.

Mines making 240 rwhp and 189ftlb with a full CES exhaust

Yeah, that's one Dave put together. He is a good guy. Cheers Kel.

Spoke with Bob, agrees there is something really off regarding timing.

Bikes going to NJ, not risking piston/valve unholy union again, and frankly I don't trust anyone with a wrench in their hands anymore.

Proper engine builders are a rapidly dying breed in the US it would seem. Yet another tick in the box for "time to move to Australia".

It's in good hands with Eddie.

I do my own work. More satisfaction that way. I have a top notch machinist at work that took care of a lot of the work done on the Harley and I have a good friend who owns a repair and custom shop that is really good at turning a wrench or two. I have gone to him on several occasions when at odds. When you do your own work the only person to blame is yourself if it doesn't work out. Then again if it all works out the satisfaction of not only owning a fast bike but knowing that you built it can not be topped. Still have a lot to learn about the Rocket but after reading all the stories on here it just motivates me to continue to learn more about the ins and outs of the Rocket.
