Where to go for a dyno tune

I have a well set up 2006 SV1000 that I'd like to get dyno tuned.

Details:
Full M4 exhaust, modified a bit
Secondary Throttle Valves removed
Airbox top hacked off
PCIII

Rich Gibbon @ Berkeley Performance Motorcycle offered to tune it for a good price. From what I've seen he does good work. Is there any reason to take it somewhere else?
 
+1 for BRG

I have had work done at both places and trust them both with my bikes. If you are looking to improve HP and get that air fuel mix just right throughout the powerband then you want the dyno tune.
 
There's also a coupon on the Riders Recycle site for a free dyno run at Mammoth Motorsports in Santa Rosa, if you're on a budget and up that way.
 
I couldn't find that coupon. Do you happen to have a URL?
 
+2 for BRG

They have a constant load dyno which far superior to inertia dynos (e.g. Dynojet) and have pretty much written the book on tuning SV 650's

For those interested in learning more about constant load pulls, here is a video of my R1 on BRG's dyno a couple of years ago (before I fabricated the new 1 piece tail). You can see the motor being held at various constant loads - this allows the engine and headers to heat soak as they do in real world track conditions.

OP, if you're in Berkeley, then go see KC Gager at BRG. Just exchanged emails with him today. Neat guy.
 
Rich, in Berkeley said $120 for a dyno read, but I don't know what type. For baseline to afterwork, unless you are race tuning, it wouldn't matter.
Both good solid shops. lick your finger, and feel which way the wind blows...jmhohthgl
 
What's the typical price range for a good dyno tune?

I'm not certain on that. Did some reading and get very conflicting arguments, both compelling.

Well I am :thumbup That's me in the booth holding the camera and KC running the dyno.

There is a reason that all serious powerplant development is done on brake dynamometers (hydraulic, eddy current, etc) rather than inertia dynamometers (eg Dynojet).

If you take the time to watch the video you will see and hear the motor running up to a series of loads at pre-determined RPMs. BRG have an eddy current dynamometer (Mustang), which allows the braking effort (load) to be varied.

Inertia dyno's can't do that, so you only get transient data.

I think I get it.
 
Hi guys
KC from Brg here. I don't get up on barf as often as I should. But I saw this post and it caught my eye of course. So I thought I'd throw my 2 cents in. Here is some information I think could be useful for you when picking a Dyno shop that would best serve your needs and checkbook.

When you're tuning an engine, any engine, the base purpose is to get all the power out that's in the motor. Yeah, I know that's a duh. It's very easy to say, but sometimes not so easy to do. Ok, so how do you accomplish this? By manipulating the air and fuel so it optimizes the air fuel ratio at all RPM's and throttle openings, throughout the operational range of the motor.
To do this you need 2 things, time and data. It take time to get anything that is custom, to be right. And you need data. I'm hoping that I'm not being to presumptuous, when I say we do a pretty good job getting all the goodness out of any given motor. To be able to do that, it is not that difficult when you know what the motor wants. With the Eddie current Dyno, and just as important the 4 gas analyzer, the Dyno puts a steady load on the motor at whatever RPM and throttle position I choose, and the 4 gas looks at what comes out the pipe. Then I interpret the numbers and make changes to the fuel and or ignition map. Then you go back and see what the changes did to the horsepower. When you're on a inertia type Dyno and they're using a wide band o2 sensor, you run through the RPM range at full throttle looking at what unused 02 is coming out the pipe. Other than a horsepower number, and only a very small picture of what's going on in the combustion chamber, what does that tell you? Certainly nothing under wide-open throttle. Even in the hands of an experienced Dyno jet tuner, the tune will never be as good as a Brg tune.

We charge $325 for your standard power commander fuel only. Ignition is an extra $100.00. We also do a Woolich tune which will re-flash the ECU--no power commander needed. That's $475. There's is a small harness that is needed at a cost of $15.00 and labor to install is $65. The Woolich tune is truly amazing.
Yes you can get a Dyno tune done cheeper elsewhere, but I'll guarantee there will be room for improvement. What it comes down to, how good a job you want: if good is ok, Then we are not the shop for you. But if you want your baby running the best it ever has, please give us a call. Every bike I do has my name on it. It has to be right.
Thanks
K.C.
