Dyno Results and Mods "Dedicated Thread"

[topher]

Hey Topher
How ya like the ride now Bro? Ain't it a hoot to hit the bottle. I'm gonna have to refill mine before I go to the track just from having fun on the hwy. Congrats.
If you have the readout of the fuel curve that might help a bit.

Like a rocket! I'm using 2 10oz bottles so I don't get much NOS time. I'll probably get a bigger bottle so I can have more playtime!

This is a copy of another thread. It's being posted here as well for preservation purposes.

To start with, I was not unhappy with the FI2000 that was on the bike. It made good HP/TQ numbers and the AFR was acceptable. But, I did pay to have it dyno tuned, most don't. The settings ended up at 2 - 2.5 - 0. My goal was to compare a dyno tuned FI2000 to the PowerPro on the dyno to see any differences between them.

My goal was to get a baseline dyno number on the FI2000 and then switch it out and dyno the PowerPro the same day within just a short time span between. That proved to be a mistake since the PowerPro didn't care for the dyno at first. It needed to be ridden for a bit to adjust to the bike. Running it on the dyno did not allow it to adjust itself properly. It did all sorts of weird things after about 4500 RPM. So, I abandoned that idea and rode it for awhile before I put it back on.

When I did get it back on, it performed very well. The chart below is the comparison between the dyno tuned FI2000 (from Jan 2011 - .003) and the PowerPro (Nov 2011 - .015). The HP/TQ numbers/curves are virtually identical. Don't pay attention to the lower HP number on the PowerPro. He just didn't rap the motor out as high so the HP number is a few down. The HP was following the old curve so I do not expect that there would be any diff in the numbers at 6700 RPM which is where he cut it off on the prior run.


The PowerPro did produce slightly more torque (122 versus 121) but I'm going to call that a statistical wash.

The real diff between the controllers came in the AFR numbers. The ProwerPro ran slightly leaner than the FI2000. This is pretty predicable since it's not using AFR as a reference, only crankshaft acceleration. This would coincide with the reports of slightly better gas mileage with the PowerPro versus other controllers.



What can I conclude from this? The PowerPro makes as good HP/TQ as a dyno-tuned FI2000. I think it wrung just as much out of the engine as one can given the other mods (intake-pipe) present. Overall, I am impressed.

That 4000 rpm wide torque above 100 lb/ft just makes me love this bike. A Busa never even gets to 100 anywhere in its curve.

Yup. Having 100 lb/ft on tap at 2K RPM is kinda cool. Still having it at 6K is also neat.

[Screamnyellozonker]

I really do believe that dumping the secondary valves cost me some midrange torque but when I start really poring the coal to it I am hoping it will make up for it in top end.

[zed]

yes I agree the power of the beast is fenomenal, running PC3 custom exhaust, and a nice tune, i will be fitting the O2 sensors back on it it will make more power with them with a finer tune, any of you guys using anything to adjust ignition timing?

[zed]

dont know if the pics worked before hope they do now,

[Screamnyellozonker]

They did work. I am using a GIPro TRE first and then a PCV ing timing module because of the nitrous. If your not using that then the TRE is most likely all you will need. Nice Numbers.

[BAD BOY M109R]

It may have been a little too rich to make max power. Most will disagree with me but a little leaner can make more power until it gets too lean then power drops off and engine destruction begins (if run that way for a long while).

like when a lawn mower starts to run out of gas it reaves up....

Hey just wondering, with all the mods done are your bikes as smooth to ride as when before the mods? My one is a bit rattly up till 2300rm just vibrates under torque if you try and pull away to over take a car, finding having to shift down a gear so its smoother,

[Screamnyellozonker]

The bikes have a retarded timing curve built into them at the factory in the first 3 gears. The TRE makes the bike think it is in 4th gear with no retard or lowered rev limit. It will smooth out your power and increase torque in the lower gears. So yes it is better all around.

[1 BAD 9]

I cant find my dyno sheet, but I remembner it was 114.5 HP / 109.5 Ft Lbs torque. My best time at a local track, 1/8 mile was 7.569 @ 92.51 MPH. I took first place, (Cruisers only race, no turbo's, nitrous allowed, and street tires only) and ran against everything except a V-Rod! There was even one guy there on a Triamph Rocket III, with a SUPERCHARGER! I actually beat him several times, until he got that beast dialed in anyway. He was really screaming as he crossed the 1/8 mile stripe...wouldnt even want to line up against him in the 1/4. I talked to the guys that worked on his bike, and he reportedly had 225 ft lb of torque at the back wheel! Makes me think someone needs to develop a SC for the 9!

I dunno that any of them are smooth under 3K RPM, stock or modded. Mine vibrates like a paint shaker if I wick it on at low revs. Part of it's charm.

[zed]

must be my imagination then, it was a while back the gf and I wore on a holiday found a rental place that had a 09 LM M109, fell in love with the beast as I nearly lost here of the back seat several times hehe, so I got my one just presently I did think the rental was a little smoother, may have to have a ride on a new one again to compare,
thanks on the reply TRod just got to have them revs up sure its smooth and sounds great up at the top end heheh,,

a SC for the 9 may prove to be a little to difficult without remodelling the entire crank case or modifying one of the cylinder heads in order to get the drive for the SC then you are faced with reliability problems like broken chain drives and snapped camshafts, the obvious other option is the turbo, and in todays age the high teck turbos on the market will be perfect with the electronically controlled variable veins and boost pressure control, can easily get 200hp at the wheel with out any turbo lag just a small turbo that spins really well,
You haven’t ran a 1/4 ,i am curious to see wot times people get on 1/4 , i am planning to get my one to the 1/4 track as soon as i get my silly clutch problem fixed..

[tbar]

NOW THAT"S IMPRESSIVE!!

So, have you found it fastest to run right up to redline before shifts?

OK here is some hard core numbers for us to use
Primary gear reduction 1.757 the following numbers will include the final drive ratio of 2.823 and a 25.5 inch tire on the speed
First gear 10.84 speed at 7400 = 52 mph
Second gear 6.91 speed at 7400 = 81 mph
Third gear 5.13 speed at 7400 = 109 mph
Fourth gear 4.09 speed at 7400 = 137 mph
Fifth gear 3.38 speed at 7400 = 166 mph
92 mph in third is 6600 rpm
Hope that helps

can anybody post the correct settings for the cobra fi2000. i have cobra swept pipes with no baffles and stock air box. i will be doing some kinda intake mod later when i figure out what kind i want. for now i just need settings that are close and will improve driveability with my current setup.

u would think cobra would have this on their web site but they just tell u to use the factory settings. any help would be appreciated

Each motor/mods is going to be different. Cobra gives you a starting place and then tells you how to go about making changes to it. With stock intakes, you aren't going to need much extra. Mine, with fully open intakes and Road Burner 2-2 only needed pots at 2 - 2.5 - 0 to make best power and good AFR.

[raynicole]

[Nemo]

Very nice. What mods you have?

[raynicole]

I have done quite a bit. Power commander, but the most impressive is the custom air intake my good friend Tony from southwest cycles in south Florida had done on the bike. I have Vance and hines pipes that were cut down with monster baffles a
s far as performance goes. Braded steel brake and clutch lines to
name a few upgrades.

Friendly Yamaha here in BR has a Brand new state of the art Dyno. I put my bike on it right before Xmas. Now keep in mine Im running RC comp 10" and a 280 metz (alot more weight than stock). It ran 110hp and 108 tq. Recently I put a PCIII back on it and had a tune done by them. This bike is Strong!!!!!!

[xSkyLinedx]

I just got my bike dyno tuned last 4 days ago and the SAE was actually showing 1 more hp than the STD.
To be honest I really don't understand that result or why we even have two standards.

[Screamnyellozonker]

In the old days you could fool the dyno's by flashing the rpms to the moon and hit the water hard. It would give a momentary spike in the power. Then after you played with the air temp, humidity, etc. you could come up with a big correction factor and instant 50 hp over what was real. SAE came out with a standard test procedure that calls for a set series of steps and a set standard for figuring corrections. It is a much more cheat proof std and usually shows a smaller number. Lots of shops will still use STD over SAE to pump up business.

Has anyone with Cobra swepts dynoed thier bike? In all the years I've been on this site I've never dyno numbers for these pipes....I'd like to see what they do....I'm sure others would too......

[VinnieB]

MOST OF THE DYNO SHEETS HERE ARE UNCORRECTED!!!!

TOP RIGHT HAND CORNER SHOULD READ "SAE SMOOTHING 5"

[ROTREXPOWER]

Just started the final stages on our conversion. Will be back on it when I get a new clutch in it on Monday. But its looking promising. Although its a rudimentry map, it got us to the redline. The drive belt had bedded in and was a little slack so there will be more boost when I run it again. We pulled 10psi on this run but I would expect to see 14psi when I run again. For the street I will limit it to around 9psi. For the strip I think we could see 240 whp and 180ft.lb torque.
