Dyno results in

damn son those are some big numbers!

 

translation?

Cool. Bhp was never a priority but good to know

I have made the following assessments of the chart (am I on the right track? - see below)

It looks like there is some improvement at the 3-5k mark

Looks like between 9-11k I'll need to hold on I don't see myself getting much benefit from this on the street but should be fun at the track..

Looks like there is no point in revving past 11k as well..

That is if I am reading this correctly.

Does that sound right?

 

definetely sounds about right to me lol

 

Is the mid-range 'flat spot' based on VF engines having a 360 degree crank with a 1-4-3-2 firing order?

(source: Wikipedia)

 

Maybe it's because there metric? LOL

 

I can see how the crank rotation and firing order can affect the HP/Torque curve but the specifics of each style are still not clear to me.

On a side note I did get a kick out of the chart noting the VF as being a 'droner'.

 

ok tink, you will not see any HP gains from those mods.
What you do get is better throttle response, so I would consider it a performance mod.

 

Take a look at the dyno chart above for the 07 at 6,800 rpm, you will see the dip at the vtec trans.
I have not seen this dip in any VFR's other then the 6th gen due to the vtec.

 

ound: lmao must be the reason!

 

I did not get any fuel ratio stuff. He has not sent my chart yet. I had to revert to the pic I took on my phone..

As for the other stuff NFI...

 

The PAIR block is a requirement for FI bikes being tuned with a Power Pommander, so you could say it is a performance mod.

Brother Tink, I regret to inform you that your dyno numbers have already been altitude adjusted for sea level. In other words, those graphs are only accurate whilst riding butt naked in the moonlight down Daytona Beach. Rather than adding to the numbers when you get to sea level, you'll need to deduct 15% for cruising around FoCo, and 42% should you find yourself yodeling on top of Mt. Evans.

 

Hi everyone,

I have a tip for people getting dyno work.

After getting the bike dyno'd the idle was fast. After adjusting the idle as per the manual the bike was running crap when cold.

I decided to do some searching and found this thread:

http://vfrworld.com/forums/mechanics-garage/29099-cold-idle-adjustment-video-00-01-a.html

This was not adjusted correctly and once changed the bike was back to awesome "when cold".

This is really worth knowing about if you plan to adjust your idle. I had no idea there was a cold idle adjustment.

Thanks to the dude who posted the video. Very, very helpful.

 

I have a lot more experience with these things than you might think. Of course, that doesn't mean shit in the rarified air of FOCO. My guess is that you know more about what you have read, than practical experience, but that's just a guess.....
