Just got dynoed, 130 hp does not impress me

pcv works fine on a roadster

It also works with the autotune they have set up for the roadster as well. Bruce and I installed the PCV with autotune to cook at the mid and low range since dyno dwork is done at WOT. Bruce is running it on his bike now.

yes but with the tors and the KN filters, shouldn't I have gained approx 10-15 hp compared to stock?
otherwise, the mods are just for show..

ONLY if its retuned properly

I have so many friends with older rockets that just overtakes me! why can't I have the same numbers that they have. the Roadster is supposed to have more power? that's why I bought it.

Here's a seat of the pants comparison: I started with a 2006 R3. Before I sold it I bought my '11 Roadster for the ABS, so was riding both. I always felt that the '06 was faster. It had stock air filter under the seat, exhaust, etc. I suspected that the secondaries were removed (or something?) to account for the difference.

After selling the '06 I got around to putting 2780s and TORs on the Roadster and physically removed the secondaries- big improvement, but still not sure it is faster than that '06 was.

I've not dynoed her, just running the TuneECU for my setup. My next move is a free flowing crossover pipe to replace the restrictive mass (there is no CAT in Roadster crossover) currently in place.

I'm watching this thread with great interest (thanks), as I feel that there is more available power to be extracted from my Roadster from my current setup. I thought a custom tune might be it, but you seem underwhelmed.

Forget the numbers for a second, did you notice any significant difference in seat of the pants performance after the custom tune?

It seems there are some variations in performance out there, even between stock (or lightly modified) bikes. The Lifted the front thread, for example seems to reinforce this.

Maybe because, unlike you, I'm the only Rocket 3 in my area, I'm not losing any sleep over this. The bike is crazy fast and ta' ta' torquey. Still, one can always want more.

This thread is older than dirt .... i wouldn't expect too much conversation from the OP :roll:

So while this is old, it is clearly showing up in searches, so I'll input. Reasons the OP only pulled 130...
1: The redline is set too low, peak power tuned will be above where it cut off.
2:. Timing is weird in his map, apparent by the shape of the plot after torque starts to fall off.
3: Manufacturer numbers are meaningless. You can't simply take a precentage and say that's how much is lost to parasitic drag, it doesn't work that way.
4:. The roadster is down between 3-5 hp compared to a healthy standard/classic when 100% stock, but that goes away as soon as the exhaust is changed. Roadster typically right at 118 +/- a few, older R3s usually low-mid 120s.
5: Different dynos, different calibrations. I don't believe ANY stock engine R3 has done over 160hp on our local dyno regardless of which intake/tune. It's a VERY stingy dynojet.
6: Will get a 100% stock bike strapped down and tuned soon to have a frame of reference.

All that said, I know certain member here on the forums did like 143whp with TORs, catless crossover, and RAMAIR on a tuneecu tune on said dyno, I was quite surprised. The same day two other bikes we're dynod and make exactly what they should, so it wasn't giving out free hp lol.

One more note:.

There's "free" power to be had by adjusting the cam timing using adjustable gears. Same cams, re-timed, should be good for about 8-10 more whp after being timed in a "not so ridiculous" way.

Taken a step further, a second exhaust cam substituted into the intake position and timed at a 107 lobe center for both intake and exhaust should yield good results.

Below is an approximation of stock vs dual exhaust cam on 107 centers, you can see there's a small trade below 3,800 for a good gain up top, which will help the bike not feel like it falls off so quickly (this is flywheel HP/TQ):

CES/RAMAIR/Dual Exhaust cams = Red/Light Blue
CES/RAMAIR/Stock Cams = Green/Dark Blue

If he's still around, tell him to go see Scott's @Steel new tuner!

WELL STEELS bike has not been modded and has over 135000 miles on it and was done on the same DYNO as the other bikes around here

Just got dynoed, 130 hp does not impress me
