Fellow 14 riders I'm interested to see results of your Dyno results after installing Brocks CT series exhaust ON MY 09 ZX-14 SE STOCK motor. I had my bike Dyno'd Sat and my results was very conservative 170.65HP / 96.88 Torque fuel 89 pump gas PCV W/Brock Street Map, GiPRO ATRE, see my signature for my bike setup. I'm comparing my results to the Dyno results Brock has posted on he site using an 06 zx-14 w/flies out. Now my flies are still in is the only differece I see between the bikes. Surely the removal of the flies won't cause such a large hp chg... will it?

Shouldn't make any differnce except maybe below 3500rpm which I believe does not usually even register on the dyno.

You sure you just didn't get an obstinate dyno? First time I've heard anyone report normal #s with brocks. HOw does it feel when you ride it?

I had the dyno done at MARRS Performance in Fayetteville, TN. Dan the owner who done the Dyno thought it was a little odd considering the results that he saw on Brocks site for an 06 zx-14 making 187hp. As far as any difference in seat of the pants feel I think that is in part mostly from the gearing change 16/43. A friend of mine went out Sat and did a couple of roll-ons at about 70mph... he's about 165lbs and I'm 246lbs, he would pull about a bike length lead on the two runs we did and once I get into 4th gear I'm starting reeling him in and pass him, I'm about 246lbs. I'm just disappointed with the gains I've gotten for the investment. I will be in contact with Brock to see what could be holding me back.

bank, first you need to reinstall the stock system, dyno the runs and then call Brock. Not fair is this game of gamesmanship. Maybe yours is more 169'ish and come on, that 1 found hp for the bang is your buck.

But if your stock [pipes] makes more hp than the Brock... Case closed. See your position either way?

I find it completely stupid to compare bikes from different dynos. With Different brand of dynos, different weather, different elevation, it can all make a big difference.

What I have always done, is I also go to the same dyno, I dont care if my ZX14 only does 150, its my starting point, as long as I go up from there, thats all that matters. Now if I did 150, and 1/2 hour later my buddy with the same mods does 180 on the same dyno, then id be pissed and trying to figure out whats wrong. But to be within a couple HP, there are way too many variables.

Kolk has a point. You and Dan need to do a little R&D right now. See if he'll throw a few WOT's just to get a baseline. And no, you do not want this to drag on, you decide to do this 4 months from now and it's snowing/damp/etc.

Hub, Dan did 4 or 5 WOT for me all in 4th gear we didn't do an avg but he has my results. Dan is a authorize Brock reseller and is willing to work with me and Brock. I'm not slamming Brock by any means I just want to make sure I don't have an problem. That would be the ultimate route to go and something that is out of the question until winter. I would've loved to have baseline and have a before and after result. Here is a copy of my Dyno sheet.

From AlienHead to CT singles or Duals, I don't remember seeing any numbers under 175 hp so it's definitely not the pipe. Your torque is pretty low too. I barely cracked 100 and thought I should have been at around 102 but crisp and cool weather should give me an 180hp-102tq so I'm waiting for fall for the custom tune! Brock will probably tell you to get rid of the K&N and go OEM as far as the filter go. I have read that some make you loose power. Check the ZX-14 diary on Brock's website.

I couldn't read what temps your dyno pull was done in! The graph above is the first and only pull and it was humid and close to 90 degrees that day! I'm using a stock filter with the back screen removed, filter had about 6k miles on it. Also how many miles on your bike? 08-11 take longer to show their true potential.

As far as the Brock's numbers, mods are on the graphs. The 187 hp ZX-14 has o weight oil, o-ring-less chain, and maybe race gas. Basically it's set up for the strip!

Kolk is right though... you're not that far off of the average I'm seeing with the same mods and you're on a different dyno in hot and probably humid Alabama!

The run conditions:86.17F, 28.69 in-Hg, Humidity: 36% STD: 1.07 my bike currently has 4707 miles on it. On the test 14 Brock is using it shows 89 oct gas, flies removed and TRE. There is nothing about type oil being used, I'm running AMSOIL 10w30 synthetic.

If you want to try and compare numbers, how about this.

On the Brocks Map I had, I barley did 150whp, first pull was 148, 2nd was 152. Then we flashed it a previous ZX14 that Jerry had tuned, and it did 169 on the next pull. Then after further tuning, I was around 177 or 178 with 103 Tq. He said most ZX14s on his dyno usually do low/mid 170s with all the basic mods depending on weather. He also said, most 14 owners wont listen to him and will only run premium, and he has had several 14s normally put down around 2-3 more whp on 87octane, which I was using due to his recommendation.

Mods at that time was BMC Race filter, no flies, Brocks Long Street Meg exhaust.

And Im using that same dyno to tune my current Turbo setup, so I can compare it to my old NA and old Nitrous numbers.

I'm pretty sure it's your mileage and the weather! I bought mine with about 3000 miles and she was running super HOT on long trips etc. After another 3k miles and better weather, I'm sure you will pull solid numbers.

Beside Kolk, another member here with an Alien Head had low numbers. A custom tune got him 5 hp and he ended up with 175 hp if I remember correct. I forgot is username but check the dyno room section. He's got a 2009 special edition (black and green) with "comfort" handlebars.

Don't be shy about asking Brock's for different maps. I got three maps from him (one was wrong)but when I tried the one I'm running now, I knew it was the ticket. My tuner say I can only get 1 hp here and there and maybe 2-3hp on top with the reflash. The only thing he adjusted was the idling which was too rich. I use 89 octane and set my TPS following Ivan recommendation. Good luck.

Dan my tuner says thats a good map that I have from Brock and and If he was to tune it he probably wouldn't get no more then 1-3hp and improve my A/F. I'll try the stock air filter before I re-Dyno, I read it on Brocks forum about that. I've posted to Brocks site about my situation I also gave him Dan's contact info if he needs to talk to him. But I would like people to post there Dyno results using the CT series exhaust. I just what to get a concenses.

bank, my sponsor buddy has a dynojet dyno, lets me borrow things. The one time I borrowed the shop book to the dyno. The instructions say, and you can watch the dyno runs [on the net] to see if these guys are following directions, but it takes a minimum [says the instructions] to eliminate any phantom number that the dyno my expose. It says it takes a minimum of 4 runs before you pull a real number outta the hat.

So it's warmup, pull, run back down to 2,000rpm and begin there again 3 more times[as you've probably seen]. This blows out any rich running, any debris that can be cleaned off the spark plug at a higher rpm range and all that carbon being blown out the back. 4th gear is the constant from 2k rpm to redline = Are your consistent beginning marks for that one HP number.

As fast as you can strap the bike up with the stockers, you just time it in as you roll the bike on the dyno. The engine is warm enough so as if it was cold you be there 10 minutes more. This way you are in and out and off the dyno. Buy [him lunch] the time he lights up the computer to warm up, he sticks the sniffer in the pipe, straps the bike down, it's under 10 minutes to my kind of experience watching mine have at it.

I think the cigar humidifier for HP numbers goes something like this? :

Sea Level ~ Air pressure @ 14.7 psi
70°F ~ Room Temp at
29.29 ~ in Hg ~ Sit at the dyno and keep watching that number climb up/down to it.
69-70% ~ Humidity [water = packed w/oxy]
240-260° ~ Engine Temp
PULL!@ ~ HURRY!

The CT-Dual is a rare exhaust, you aren't going to find a lot of data on it. Also Brock's map is so close that people don't bother putting the bike on a dyno. My advice would be to put the OEM filter back in and add at least another 3k miles before your dyno the bike.

Good call, dKing. If the OE filter makes more hp, where is that K&N coming from if they boast 'increases pee forum ants it ain't happening on some bikes' was I needed HA magnifier to read that line on the box. Now, where did I read that?

You know bank, it's really hard to find hp. Sometimes it goes well, sometimes it needs 3 or 5 more operations to leap over that tiny bit you go chasing that, 'every little bit.'

That 170 doesn't sound that bad. Depends on the dyno really. You could go to a different dyno and pull 180hp but what does that do besides make you feel good. I have the 2012 14R with the single sided ct exhaust and I pulled 201hp. And on the same dyno a 2010 with a different full system (dont remember) pulled a 173hp. So yours seems to be about right. I had the 09 se with brocks alienhead full system and on a very happy dyno I pulled in the 180's but like I said the dyno was way off. It had a r6 pulling in the 120s.

If your that worried about power do what I did.......forget about the exhaust, upgrade to the R!!!!!!!

zx14racer
Yeah I was headed to pickup a pearl white 2013 zx14 in ATL when I came across my current bike, I was made an offer I couldn't refuse.

Honestly your bike is a great bike. Really not that much of a difference unless your pinning the throttle everywhere you go in a straight line. I only sold my 09 because I was buying a bigger home and thought I would need the money. I loved the colors on my 09 SE.

Ok after consulting with one of Brock's tech guy's and reviewing my Dyno print out... my power killer is the high correction factor the machine had 1.07 and weather. There are some things I can do for my bike so I'll repost my updated Dyno sheet if there is any changes. But please still post your dyno sheet if you have any of Brock's CT series exhaust installed.

Thanks Don
