Getting my bike Dyno'd today.

[Rocket Scientist]

Well I'm happy enough with the result.

I turned this,


Into this,


and got this.


Good increases in power till 6000 RPM then a drop of 3.5HP (2.3%) over the next 1200.
TBH, I don't spend much time riding over 6000, so I'm calling it a win.

No idea how to convert tractive effort (lb) to torque (or is it the same thing) but seems to be a big increase in that as well in the low to mid range. 560+ up by about 30 lb.

Hmmm......that looks like aseptic grade stainless tubing like we use in the food plant where I work. Kind of pricey isn't it ?

Yeah I remember him saying it was but he wanted a natural look if you were going to powder coat it you could probably do it for a lot less or you could chrome it but that would bring the price back up

If that is 316 (even 304 I believe) stainless it can be buffed to look just like chrome.

Yeah I think that was his intension as the one he had one he had on the day he passed away was only version #2 with #3 on the Way, he spoke about polishing it or powder coating

Just a snipet to help understand why things do what they do, this is what i know and please correct me if i am wrong.
Another reason for the low to midrange gains is the inlet tract length which is why Warp went for a common air box with a hi flow cleaner element using the original velocity stacks.
To explain it differently we can use the tech advancements in super bikes the early Fireblade's and R1's were very peaky hi powered but little torque they used ram air with short velocity stacks which is great at speed but did not help coming out of the tighter corners so a smart cookie worked out that to produce more torque they needed to slow the flow they achieved this by using a valve in the exhaust and longer inlet tracts the exhaust valves worked great as they were ECU controlled but then they couldn't get enough top end power that is when they developed the variable inlet tract velocity stacks this works by lengthening at lower revs and shortening at higher revs, servo motors do this on command from the ECU at the same time as the ECU opens and closes the exhaust valve and different times. This package is why the modern sports/ Super bikes are so much easier to ride and don't have to be ridden at max revs all the time, all this stuff was developed originally on the proto type class racing bikes known as MottoGp

Must say there looks to more room up front than I was expecting to have so there may well be some manuevering I can do. I'd like it sitting in a bit anyway and the front could be shortened - although I won't to making any changes to this unit. It stays the way it is so cutting the rubber tubing is a much as iI'll do. Doesn't feel like the filter's hampering things too much but if I can get a K&N to fit I'll try it. The colour on this one goes well with bike though.......

It is quite heavy. I'd like to look also at getting them made out of a lighter material.

actually it really was not That heavy probably the heaviest part is the filter

on the weight side of thing I could weld a tab so yo could fix it to the tabs hanging of the back of #1 and #2 Throttle bodies, even if it were made out of Alloy it would not be very much lighter.
A good way to see how much restriction is in that filter would be to go for a run with the filter of, .... the odd bug wont hurt her just stay away from new road works

Hmmm.......Carbon Fibre would look sweet......

Just a thought.....

If it is falling over at 6000 rpm on the dyno...

Would it change the falling over if you were running 150+ mph....wind

or just a fan blowing on the front of the bike.

Not heavy compared to, say, the rest of the engine , but still about 5-6 times heavier than the triples. I'm just guessing but all that heavy gauge stainless probably weighs more than the filter, but just guessing as I said. I actually took the Caliber filter off and it weighs only slightly more than just one of small K&Ns.

Had another good look and on full lock there's no clearance issue with the indicators at all. I can see that if I shorten the rubbers by more than about 3/4 inch there could be though. I think Cobba must have been using much shorter ones. Don't want to pull it in just at the back as that would make it point out. Think I'll leave them (the rubbers) for now and give it a run with no filter first. Then if needed get a K&N on there before fitting it exactly. Only problem with that is going to be my driving lights - they'll have to be moved.

Exploring fabrication options and might even flick it up the QLD for someone TC knows to have a look at. CF would be nice too.
