Dyno results in

OK I have no details on what my bike was stock before anyone asks.

Since buying my bike (Blue VFR800 2001 model @ 55K) I have added the following:

- Basic service (plugs, oil, oil filter, coolant)
- delkevic stainless header (without cat)
- GPR hi rise exhaust
- Flapper/snorkel removal
- K & N filter
- Smog block off plates
- Power commander 3

All of these changes were completed over time and its hard to gauge what mod did what and so forth.

Here is the final dyno results

Max HP 106.45
Max Torque 58.01

I am having difficulty attaching pic so stay tuned. The file is being sent to me today.

 

Dyno

I am not sure how many 10 year old stock VFR's would be performing at 110bhp Mine was at about 102 prior but was not using stock map.

Ridability has improved heaps and that would be what I think is the biggest benefit. All jerkyness in accelleration gone and the throttle just wants me to keep turning it.

Its definately great to know its running at its optimum.

You could say the mods did nothing, if HP was the only factor. I have seen another guy with dyno results of 109 but thats the best I have seen on a dyno chart.

I think the HP gains are marginal for what you spend (it seems the consensus on this site).

Ridability gains however, to me are substantial.

 

Good stuff Pap11y,
All it needs is a coat of red and she's good to go... LOL:vtr2:

 

I am not man enough for red

 

Pap11y, where did you have it Dyno'ed??
Did they touch it up much??

 

http://www.doinbikes.com.au/ were the guys who did the work.

Touch it up? HP was 97.73 to start I think (I can't read it clearly on the phone pic I have). The torque changed slightly (I will post the chart when it arrives)

So with the tuning he got approx 7hp extra out of it. I did not have the stock map. I had loaded one of the 5-6 options I could find for my bike but none were really close to my setup (in description).

I had to laugh as he said "VFR's usually run rich after 9000 but I have sorted that and it will be fine"

I replied "mate I never get to 9000.."

That being said the bike will be fully setup for track days at the end of this week.

Hopefully I can find out what he was talking about at Eastern creek

 

While peak HP may look good on paper and sound good at the bar and internet forums, increasing power throughout the rpm range will yield far better performance gains even if a couple ponies are sacrificed on top.

Have you done any suspension work Pap? A hundred bucks spent on proper springs and fresh fluid will improve lap times more than a grand in motor upgrades.

 

I agree thats very important. I have replaced the rear shock with an ohlins HO801 and the forks are getting rebuilt with ohlins springs/valves.

The front was shot and I would get bounced through rough corners. It didnt make me want to go faster

I had been debating whether to get a VFR and a track bike, and I finally decided to make my vfr into a track bike.

The cost was about the same

 

You know, everytime I ride mine I feel like it would be able to do pretty well on the track. Then I look down and realize that just getting to the ton mark pretty much taps everything she's got. I did two sessions at Barber on a cross country trip two years ago but I had only done two trackdays prior to that so regardless of the machine, I wasn't that good (but still got a knee down). I really love the power delivery and sound but I think the weight would really prevent a decent pace. The pristine fairings also limit my lust for the track. There's a VFR of some type at nearly every trackday I've been to. I can't recall any running above the beginner group though.

Good luck with yours. What are you doing for fairings?

 

At this stage I will repair my fairings. There is damage on both sides. I still haven't decided which way to go with that yet. There are plenty of replacement options online at this stage so if I feel the fairings are at risk I'll get some race glass. I don't expect to be pushing to that extent in my first year. I'll be concentrating on throttle control and corner entry speed to improve my skills.

As far as track days, I don't expect to do more than 4 a year. That being said I ride every day so will get the benefit of the changes every day I ride.

I had a zx-7 and it was super quick (at the time). Would have been awesome at the track but was shit riding around balmain (inner city sydney).

I didn't ride it near what it could do and I think it will be a couple of years before I am exhausting what the viffer has to give.

I will always keep it and when I think I need more, I can get a purpose track bike..

 

you guys know that they are rated at 110 hp at the crank not wheel right? after you figure a 15% drivetrain power loss youd be lucky to see 95 hp at the wheel. so when he says the bike put down 106 whp and you say the mods did nothing... lol :crazy:
gaining over 10 wheel hp is almost unbelievable on a vfr. provided this is on a dynojet dyno not a knockoff or mobile dyno id say this dude did a damn good job. with that being said lets see a print out already lol.

this is what a brand new, stock, well maintained vfr800 will put down on a dynojet dyno:



so id say those mods did a lot!

 

I'm gonna have to con a dyno centre into letting me do pre and post mod runs.

Pap, You will love Eastern Creek.
Did an Advanced Rider course there last month.
It was humbling to see how slow we were on the track compared to guys who do it regularly.
I went around turn one at about 120-130km (with my eyes bulging) and those guys were doing it flat out in fifth.

 

i hear you on that, the snorkel/flapper is only good from anywhere from .5 to 1 hp. but the sound is worth about 50 hp. lol
and the pair block off, well is worth nothing, but it is necessary to get accurate air/fuel reading for tuning purposes.

ps im usually all about the red, but that candy blue looks awesome!
