What is the real HORSEPOWER 4 the ZX14? I know there is alot off variables that can effect horsepower ratings on a dyno but i was looking at the power for the Yosh full system on this board and it was 170????? How can that be when Sportrider or was it Sportbiker just had a write up last month on a stock ZX14 with 174 RWHP and Cycle World rated it at 170RWHP. I have Brock's GEN 3, power commander, flies out and definitely feel a difference. So how can the yosh system just produce 170rwhp? Anyone dyno Brock's Gen 3 yet?

Yes----I went from a stock 169 to 186.2 with the Brock system and map--same dyno.This is with the secondarys removed. Dyno guy said he could not improve on the Brock supplied map. Tire distroyed.

The dyno is just a tool.....there will be variations between bikes too. There are sooo many things that can affect #'s...weather,humity.elevation,tires,chain,stretch even the weight of the person on the dyno. It's just a tool that will give you a ideal of what your bikes capable of. Dont wory about the numbers...any aftermarket exhaust is usually with-in 1to3 hp of each other and that could be differnt dyno number readings. Hell with hot oil you can pick up a hp or 2

Mine stock was 162 SAE, smoothing of 5, on a DJ250. 178 Brock'd and PC'd. That was a custom map, 'flies intact. Elevation here is about 850.

The easiest way to get more measured horsepower is to just use a more generous dyno

The manfs test bikes at random during production and the bikes that put out the most power are sent out to the mags......help them look better on avg. I live blocks away from Primedia - Motor Cyclist - and know that the dtnos they use are a bit optimistic. The only dyno I use is run by one hell of a tuner/racer and everone says they get lower numbers from him.......cuz they are REAL numbers.

I don't care if the engine makes 50 hp or 300 hp on the dyno...Dyno is just a tool and used as a tool is very helpfull ...But the best test is the track, trap speeds don't lie and is the best way to read hp...

I saw a dude at Road Atlanta this weekend pay thirty bucks to get his heart tore out.He may or may not be a member of this board but he was sick when they told him his numbers.Older gent,06 zx14 with muzzy pipe and no PC pulled 162hp on this dyno.I dont know what model it was or how it was set,but i know this guy was almost embarassed when they told him the figures.It had drawn a pretty big crowd since it was a 14.He was under the impression the bike had 175 stock and with the pipe he should have been 185 or so.I told him without PC and some tuning his pipe might not be doing him any good.

I understand variances between dynos...but if you look at the sheet from yosh..it looks like the pipe only picked up about 5hp over stock ON their dyno. The graph shows stock, slip-ons and yosh full system if you look at it. Also in the pictures of the pipe..check out how small the pipe necks down just after the collector. There has also been a post on here that showed that a Brocks and Muzzys both tested on two different bikes that started out within one horsepower of each other, and both tested on the same dyno that the Brocks made something like 8hp over the muzzy's. ZX-14.net also just dyno'd a Muzzy's alonside a set of slip-ons, once again on the same dyno and found the slip-on made as much or more hp than the Muzzy full system. Every body that I have seen dyno a Brocks system is getting anywhere from 12 to 17hp gains over the stock system when run on the same dyno. So, NO not all systems are within 1-3 hp of each other. Just my $.02

I was at Road Atlanta this weekend and my totally stock 14 did 158.2 hp!!! It went 184.5 mph when the speed limiter kicked in. WTF!!!! How are stock bikes doing 175 hp? I guess it's not worth it to spend $1000 for 4 hp! I still love this bike and its PLENTY FAST enough!

Brock Davidsons explanation during purchase to me....
stepped, larger, tuned length primaries, 4-2-1, and larger secondaries....
Brocks pipe is not a copy of the stock header configuration or dimensions like many are...
He does not simply reproduce the factory piping and turn it into a 4-1 system.
His systems are built from a clean slate, and tested many times over until tuned.
Call it a sales pitch if you like but seems to have rung true!
Thanks again Brock!
I think the only systems that will be close to his will be the Ti force or MC xpress.
Lee shierts tested a shit load of pipes for the 05 gsxr, and the time slips for Brocks were #1.
Ti Force a very close second.

Well hell I was just wondering for my own idea of what the bike had with a pipe, power commander. All I can say it there is a definite difference with this Brock's set up. The other nite I was out with a passenger, she weighs 103lbs, and a CBR954 decided he wanted to play normally I keep kool if I have passenger on board. There wasn't much competition and couple times I let him "get away" and when i hit it hard i could reel him in and just fly right past him. What I like most about the bike is the flies being gone, the power is rite there all the time now.

My .02.
I know that I am 45 pounds heavier than before my surgeries, and the 14 was laggin below 6000 rpm's. With the flies removed, the new exhaust, the pc with custom map, and sprockets at 16/42, I can launch.
Most of my friends have litres, or less. They also weigh in the 165-185 range. At 245 (with no gear on), I can now launch and be competative with the litres and the middleweights.
I have had problems believing in these dyno numbers, and I just know up to 170 my bike is one of the fastest around.
The advantage to the exhaust that nobody seems to talk about is how much cooler the bike runs. With my mods, on the freeway, my bike never goes above half on the temp guage. That's worth the 1000.00.

I've never had a heat issue with this bike. Always runs half or below on the temperature gage even in 90+ weather. The only time it goes 1 bar above halfway is in stop and go traffic. With temperature here now in mid 70's just running 1 bar on the highway.

Ok checked with dynojet today...they claim that all of their dynos are withing 1% of each other unless someone is intentionally playing with number to make it read high (yes this can be done). Just got my bike off of the dyno again today...Brocks Gen 3 carbon, zx-14 PC III power commander, and TRE all with Brocks map for this combo installed. 187.7 rear wheel horsepower. The same dyno showed 173.8 rwhp when my bike was stock with 1700 break in miles...todays run was with 3200 milesplus the bolt ons. The stock 173.8 rwhp was on a dynojet 150....I took the bike to a local Harley dealer the next day and put it on their dynojet 250 and got 172.6 so two different dynos a day apart within 1.2 rwhp. 187.7 rwhp...I love this thing. You know how much money I had to spend and what kind of gas I had to use to get these kind of numbers out of my old GSXR's LOL.
