LDH HELP,AKRA EVO DYNO

LDH,need some help trying to figure out whats up with my dyno run.this is how it is,my 1krr has 473 miles,full akra evo system,air filter mod,it dynoed at COOL SPRINGS HONDA @ 148.47hp.thats less than some stock bikes.he showed me some other dyno runs on stock bikes and they were in that range,showed me dyno run with a micron slip-on that made 149hp.he had said he thought the bike should make more power and i thought the same also.was thinking in the mid 150 range.did not have dynoed before i put the system on,he also said that he was getting a couple more HP with the 1krrs with the CORSAS on them.im just wondering if the air filter mode hurt me in this case?LDH where do u get your bike dynoed?i know u do your own mapping,but where.COOL SPRINGS is the nearest power commander certified dyno and its 3 hours from me.your only about a hour.

In order to have unlimited access to the dyno I actually have to either drive to Nashville (2.5 hours) or St Louis (4.5 hours). Yea it's pretty far for me, but I'm willing to do it for the testing time. One weekend I actually drove back & forth to St Louis twice cause I had to run home & get more parts to test... :D

Anyway back to the topic at hand.

#1 Your bike will most likely loosen up & produce more power after the motor gets really broke-in. Bikes usually start making the best power after about 1500-2000 miles. Everybody always talks about engine break-in, but they never mention transmission break-in etc...

#2 Yes it is possible that with the air-filter mod alone that it could hurt your performance especially on top end, but it's just speculation at this point cause it could be helping too ya just never know until you test it both ways & get some mapping done.

#3 Finding a qualified dyno tuner is a lot harder than it may seem. You would be amazed at how many dyno operators just simply don't know what to look for or how to get an optimal mapping.

yeah,i have read just about every thing out there.i just thought i shoulda had more hp.reckon that the pipe even made more power than stock?he also said i lost a little torque over the stock 1krrs he had dynoed.you go to nashville,where do u go there?thats where i went to COOL SPRINGS HONDA about 3 hours away.i live in jackson thats about 1 hour north of you.

Partner of mine has a private dyno in Hermitage which is just outside of Nashville

As close as you are you should come on in & ride with us MSSR guys on Sunday's. Straight down I-40 to exit 20 is where we meet

F4I how did the graph look on the dyno?
not every bike will put out the same HP as the next also..you can dyno your bike on 2 different days and get 2 different #'s..how often was the dyno calibrated? if they dont keep up with the hourly maintenance that would give you a lower # also..lots of things could to consider..but your bike didnt lose peek HP by adding a full Akrapovic..
theres a place in NC if your any where near there called Lee's performance in Charlotte they make some fast bikes and have a dyno room ..

If you did not dyno your bike on the SAME dyno/same day right before installing those mods, then you have nothing to compare to. Your bike could still be making 10HP over stock, you just wouldn't know it.

LDH,im so disappointed in this exhaust.so i get home last night start taking my bike back apart to put the stock exhaust back on,so i can dyno it,to see if i gained any HP with AKRA at all.ordered new air filters too.going to dyno it with stock exhaust with the air filter mode.thats how i dynoed it with the AKRA.then im going to put the stock filter with no mode to see what diffrence that might make.just to many stock 1krrs that dyno at that hp in the high 140s,147 148 149.also emailed AKRA to see what they say.there web site graph shows no loss of HP or torque from 4400 rpms.Hardracing dynoed there bike with 300 miles,it made 150hp stock,dynoed 163hp with the Micron system.i believe that Big Valley honda also dynoed there stock bike at 150hp too.hey what time do u guyz meet on sunday?where did u order your BMC filter?

8am on Sundays.

However tonight is Sportbike Night at Joes Crab Shack just off of exit 18. I've only been to 2 of them ever, but I am going tonight as is most of the MSSR. They start showing up around 6:15 to eat & socialize. You should come on out this evening.

You can't compare what other CBRs are getting on other dynos.
It just doesn't work that way. Two different dynos can be different by 20 HP! My completely stock CBR1000 got 130 HP, while some mags are getting 153 on a completely stock bike. That doesn't mean my bike is down by 23 HP - it only means my DYNO is down by about 20 HP.

Don't get all upset because you're down on power compared to BVHonda's results. It doesn't mean jack.

Jrod,that means my bike would dyno in the low 140s,141,142 not seen a dyno run thats that low have you?this is why im putting the stock exhaust back on to see what it is makeing.all the dyno runs he had done on the stock 1krrs were above the 145 range.he had done about 10 or so.he just got his 1krr told me he would let me know what it dynoed with less than 100 miles on it.dont get me wrong would be happy if this was a slip-on.but a full system and everybody else is getting in the 160 range.have had this system on all 3 of my last bikes and they all made more power than the stock on average about 7-8hp over stock.i did not dyno those first but they all ended up with way more power than the dyno results i seen.im talking about magazine dynos and real world dynos.this is not even close on my 1krr.

Ok, I read it twice - still not too clear on what you're saying. I'll try to take it step by step:

"that means my bike would dyno in the low 140s,141,142 not seen a dyno run thats that low have you?"

Did you read my post above? Mine got 130 HP (133 corrected) bone stock, on a dyno that reads notoriously low. Yes, I have seen a dyno that reads low, if that indeed was your question. You got 148 HP - with your mods, you'd expect an 8 HP gain - not unreasonable. That puts you at about 140 HP stock - again, not unreasonable at all. I'd be very happy with those gains. Don't compare the peak HP number, but compare the GAINs. BVH gained about 12 HP with a full system, PC3, and race gas (or 8 HP with just the exhaust). If you get similar gains, it doesn't matter if your peak HP is 120HP.

The only way you're ever gunna know is if you dyno your bike completely stock, then again with the exhaust and PC3, and then again with the air filter mod. All on the SAME day, SAME dyno. It's unrealistic to expect to match the 160+ HP numbers being produced on a completely different dyno.

Jrod,i understand what u are tring to say.but let me see,i did not ask if you had seen a dyno that read low.i asked have u seen a dyno run or pull that read that low.u said yours dynoed at 130hp what did the other 1krrs dyno at on the same dyno.[were they close or average to yours]if the answer is yes then you can say that the dyno u use reads low.see if yours dynoed at 130 then the other stock 1krrs should be close on that same dyno if not then your bike is down the 20+ hp.the 10 or so 1krrs he had already dynoed were in the 145hp range NO 1krrs had dynoed any lower on this dyno.i know diffrent parts of the country,such as sea level,temperature,humidity,etc.do effect the dyno readings.but im talking about the same dyno.u said dont compare peak hp but compare the gains,thats what im trying to say.out of all the dyno runs on the other stock 1krrs i did not gain muchif any.if u take the avg of the ones he had dynoed.that would mean that mine would dyno the least amount of hp stock out of all the others he had dynoed.140hp is not even close to his avg stock hp dynos.

Paragraphs man, c'mon!

I think I understand what you're saying. So you're saying because other CBR1ks got 145 stock, and you only got 148 modded? By your logic, yours would probably get 140 stock - or 5 HP less than some other stock CBRs on that dyno. Right?

It's perfectly normal for identical bikes to be off by a few HP, even 5, on the same dyno. I think Hondas have been known to vary a bit between bikes too.

You also might be on to something about the different tires. It's possible that the BT014s are heavier than the Corsas, making them read lower.

Tires do make a difference, according to that article a couple months back (Sport Rider I believe) the Corsa's should read slightly higher on the dyno.
