Weather conditions greatly affect a bikes performance. At the 2 extremes you could see upwards of a 5% delta in power... It doesn't sound like a lot but if you've got a 195HP super-sport that could be 8+HP. Best time to hit the dyno, or break drag records, is perhaps in August/Sept. if you're in MI like me.
Exactly Brock. "Average power is what accelerates, not merely peak power." So much ado about peak speck sheet numbers these days. Engines that make broad torque just feel quicker all the time.
Hi! I hope you get to read this, Brock (or anyone else who knows what he 's saying)... I noticed the flame poppin out of the muffler and made me think about my own bike. Aside it's slip-on, it's a completely stock 1998 gsxr750 fuel injected and on the dyno it put 127hp on the wheels (dyno is prob quite right, cause my mates stock cbr rated around his listed hp...), but the guy said it tends to be a bit lean here and there and could use a mapping... now, first I had a Lazer exhaust, but since I have a Delkevic exhaust on it, which seems to be more "open" or less restricting (prob the db killer) , I tend to have FLAMES out of my exhaust on the track. And I'm not talking about a "pop", no its like till up to 8sec of flames, bout 15cm long... Does this tell you something? I really hope it aint bad, cause it gives me a lot of positive comments and even seems to make guys with 20grand bikes a bit "jealous" ;-) It's cool, but if it hurts the bike....
lillnemo1 - your 1998 is a very early model motorcycle OEM fuel injection system and your bike was not subjected to the emissions regulations of today. Not that it makes it 'bad' or in need of replacement... it's simply not as refined as todays motorcycle EFI systems. The flames you see are 100% normal for your bike and are more likely caused by a RICH condition upon deceleration. Excessive fuel in the pipe makes flames/excessive air-mixed with fuel makes 'pops'. There is no risk of damage to your engine, but the flames can accelerate the natural degradation of your baffle packing - which can create the need to repack or replace the muffler more frequently. Hope this helps - Brock
@Brock - Great video, what a difference a few months make from winter to summer conditions, and how that affects engine performance. I'm a little surprised Justin didn't ask, if you believed his bike's performance could be improved upon as is? And the STD correction method with its Relative Air Density of 99.8% (1.223kg/m3) vs 94.4% (1.157kg/m3) for SAE is a monster influence on power output. Just how many air molecules can we pack into a given volume of space? Reminds me of watching the same Super Comp dragsters up in the mountains vs when they'd race at PBIR in Florida, the bracket time differences were huge.
Another factor is how he rides the bike daily. Commuting and/or casual street riding tends to make the bike 'lazy' I was told. Mine was also broken in on the dyno and I saw some pretty nice numbers. After a month or 2 and full Yoshi R11 + p08 (no flash/tune) the numbers dropped by 5-7 hp. Now after a flash/tune the numbers are the same as the very first (stock) dyno I had. So basically it looks like I did everything for nothing but that can't be true and this video demonstrates that...
That depends on the make/model/year and usage. It can be as low as 11.2-1 (Nitrous Oxide) and as high a14.7 (Fuel efficiency mapping). Most normally aspirated applications are between 12.8 and 13.6. Check out this FAQ for more info: blog.brocksperformance.com/faq/how-can-brocks-get-mapping-so-close/
Interesting what you say about real life, have agree. Time to accelerate in real world is what matters, I've tried Dynojet autotune in the past but believe the bike was running leaner than what the lambda sensor was saying.
Maybe when you guys take it to the track you can get a 175-185lb rider on it to get an ( SAE) type Time instead of the time everybody wants a (TEASLEY) time run lol But I think you should still baseline it then do your clutch magic and show the numbers fall As always we love the videos keep it up

How do you guys tune ECUs for international customers if the fuel and octane rating varies in other countries? Do you get similar and consistent results compared to the US ones?
Not really. The Canadian gentleman mentioned had a horrible running bike when it arrived. We did the work and now have a great fuel tune for them. You can see it in action on 650 Ib's page: th-cam.com/video/7UI-1r-taOs/w-d-xo.html
Am i understanding this correctly? The base model 2017 gsxr 1000 non "r" version, has a quick shifter that can be activated with a flashed ecu? Nothing else is required? @Brock Davidson
@Jermain - correct. Of course, you must also purchase the QS/Autoblip: brocksperformance.com/flashtune-quick-shifter-auto-blipper-retrofit-kit-gsx-r1000-2017/ - we have it all in stock, ECU flash is same day turn around.
Our goal wasn't to tune or measure anything except HP on Justin's bike. Gixzilla runs considerably better in poor conditions with our Stage 1 flash and PCV with map.
What are the big differences between the dynojet and the factory 997 eddy current dyno for your fine tuning what I read (marketing) dont trust it, we know you are the man and will give us the real truth please.
They are both very good tools. We choose the Dynojet Model 250i, not only for it's measuring capabilities, but for the integrated tuning of the PCV. It's a package that no other aftermarket fuel tuner offers, and we feel it provides the best product for our customers.
We just did a test on our long-term test 10R. It made almost 194 on pump during our #sprintfilter F1-85 test: brocksperformance.com/sprint-filter-p08-f1-85-zx-10r-16-18/
That's the same bike u got what 200 plus hp out of. So the weather effect that bike that bad, I take it.
Brad Quinn he was using MR12 when he got 200+ horsepower
Thank u Brock for the pin on the video. Carzy but true.

Great to see these types of comparisons and for brock to give us another master class understanding of the results. Love it, keep it up brock! 👌😎
Hard facts and numbers, doing it RIGHT ! Thanks, Brock !
Exactly Brock. "Average power is what accelerates, not merely peak power." So much ado about peak speck sheet numbers these days. Engines that make broad torque just feel quicker all the time.
That guy was not happy with your dyno run. Lol he's like "Noooo, my basically stock gsxr makes 205hp!" 😆

Enjoy these vids keep them coming :)
What type of AFR do you usually aim for: 12.2, 13.2 or somewhere in the middle?

Fun video to watch Brock
Hell yes new vid day made!
Great conclusion numbers are just that
Maybe when you guys take it to the track you can get a 175-185lb rider on it to get an ( SAE) type Time instead of the time everybody wants a (TEASLEY) time run lol
But I think you should still baseline it then do your clutch magic and show the numbers fall
As always we love the videos keep it up
Busa1811 wolaver we have plans to make everyone happy. Stay tuned.
Think that gsxr on the 4th you mentioned showed its face on 650ib most recent video.
That was him, at the end of the video spanking some S1000RR's with MUCH lighter riders.
Brock can I make a appointment to bring my bike in for tuning I have your complete predictor system installed ? I have 2017 GSXR1KR

wished you where in Texas:) Id bring my 2016 gsxr 600 to you..that being said...have you done a gsxr 600 like this before?
We have - but not documented to this extent. It's on our todo list for this year.
Ok but now how was the kids air/fuel ratio. The bike was flashed but could his bike have run better with a PC and tune?
Our goal wasn't to tune or measure anything except HP on Justin's bike. Gixzilla runs considerably better in poor conditions with our Stage 1 flash and PCV with map.
At what engine temperature did you do the runs?
We typically start around 180F and try not to go above 200F.
Brock Davidson awesome 👍🏻 thank you for the info I'm new in this dyno stuff

How much hp on the zx-10r?
We just did a test on our long-term test 10R. It made almost 194 on pump during our #sprintfilter F1-85 test: brocksperformance.com/sprint-filter-p08-f1-85-zx-10r-16-18/
square tires?
Made 205? No it didn't, you're not fooling anyone
No Sh** it’s hot and humid I can see your 💦. Just like here in Sydney it gets humid and I lose 10bhp🙄
