134whp, 58ft/lbs @2:10 - 125whp. All stock. @5:26 - 125whp. Full exhaust, oil, adj chain, pair mod, no flash or tune. Lost few hp low to mid range from being lean. @10:00 - Basemap/mail in tune, fuel changes, exhaust valve delete, TB butterflies de-restricted. Too much fuel, no hp gain. @12:50 - 131whp. Tailored fuel for the Brock’s system. @13:41 - 133whp. Fuel is spot on, played with ignition timing. @14:54 - 134whp. Didn’t video dyno run. Raised rev limiter and other “small adjustments”. Over all, 10whp throughout the entire rev range!

[@Jmeez69]

I want to clarify some things for some of the guys who are disappointed in the final power figure for the bike once flashed.... I'm going to explain this stuff in generalities without getting into nitty gritty math. So, your average (*NEW*) liter bike is somewhere between 440 and 460 lbs wet and they generally produce, (once flashed) 180-200 whp..... A flashed 750 with a pipe will make 135 hp at the rear wheel but it literally weighs 419 lbs wet and it is simply disingenuous to ignore such a significant weight difference. So, you have to factor in the power to weight ratio. No, it isn't as fast as a 1000 but you can't simply compare 190 hp vs 135 hp without factoring a 30-40 lb weight difference.... That's what makes the gsxr-750 such a remarkable machine is it's power to weight ratio! To give a sense of how truly light the 750 is, I owned a Kawasaki zx6r that is actualy more modern, and more recently updated then the GSXR 750 yet even still it actually weighs more then the GSXR at about 435 lbs wet and it is over 100 cc's less then the gsxr..... With the 750 you are riding on a 600cc Chassis (literally) with an extra 150cc's of engine displacement and only 9 lbs of added weight. The truth is there is no other bike like the GSXR-750 available on the market today. It's a unicorn, perhaps even a Relic, but it holds a special place in the hearts of many motorcycle enthusiasts. If I had to guess the real power differential while factoring weight it would only be a difference by a factor of about 30 hp as opposed to the actual difference which is something around "60"... (roughly).

Often wondered with your mail in tune..I know your tuning with a bike on a dyno but on a mail in are you able to extrapolate the f/a via another source in ecu setting to fine tune a tune..Not every zx10 or gsxr 1000 ect ect will get their best just with flash.. I have the woolich on my gen3 zx10 and i need to learn about these timeing tweeks..Suggestions?

[@iannsr125]

From watching the first run of the bike stock , it would be interesting to see what the bikes stock exhaust can offer with all the restrictions lifted on the bike and tuned as that would be more of a fair test between factory exhaust system and brocks pipe .

[@danielresch2975]

how much did the bike weigh after putting a different exhaust on and what was a horsepower ratio from weight you know from horsepower to wait compared to a thousand with the header on that's all great job love you

If you do a cat delete on a 750 and add a power commander is it necessary to do an ecu flash to avoid engine damage?

[@MoodSwingZX]

My gues: 122 after new system I think it should loose power first 133-135whp after tune... Hmmm exhup removal has to be fixed.. I had a big deep... After exhaust change.

[@mindspinn311]

Everyone who installs full exhaust and doesn’t tune needs to see this video.

Yes to realize that on the 750, better keep the excellent oem headers, put a slip on and tune and flash like mooore did, I think the gains were for the tuning and cat delete.

[@mauserman8mm1]

@ yes headers are great I got a 2015 GSX-R 600 and cut the cat got a 125$ MJS mid pipe with m4 shorty.ftecu flash with it fine tuned on Dyno made 113 whp, only 2 hp less than r6 with full system!

[@timothy9596]

@@redline350zHR I know exactly what you're talking about. Last August I was riding my 750 coming up to an intersection and a guy turned left right in front of me. My bike crashed right into his right front quarter panel and I went flying over the hood. Then the guy takes off. A couple of people that witnessed the accident followed him, called the police and they got him. He was drunk. So a felony hit and run for him, and minor injuries and a totalled bike for me. I'm not kidding, the bike was split in half as both sides of the bike were split in two at the frame. The bike you see in the picture, a ZX14R is the replacement for the 750. I've always wanted one since they came out and I'm loving it. The funny part about the whole thing was how pissed I was after I got up off the ground and saw my bike. I was supposed to be going on a pretty big group ride the next day and because of that drunk fool, I was going to miss it. The month that followed without a bike was probably the longest of my life. I'd never gone that long before without riding. There was no fear once I got back on. The only difference is now I'm hypersensitive when I see a car getting in a left-hand turn lane, lol.

The stock GSXR exhaust has no restrictions and is titanium. The restriction will come from the cat and lean settings from the factory. Even a stock GSXR with a re-tune would get close to 135HP which 99% of people can't use all this power anyway. The headers and aftermarket exhaust are not going to get you large gains.
