Default Re: Cam Swap Pointy?

I am sure a lot of race teams would be very interested in employing you as they get rid of a lot of very over paid techinicians they obviously do not not need.


And you can measure air speed and temperature flowing into carburretors actually. The system collectively is called telemetry. Everyday cars use it along with modern motorcyles in fact they need it to run their fuel injection. A couple of These sensors are called Mass Air Flow [MAff] and Air temperature sensors along with a whole host of other clever little senors.

Like I originally said you can use the Math to predict an out come that can then be proven.
From what you say obviously the fastest bike on track is the more powerfull, rider skill aside, of course.

Good on you for apologising Dave. Have a beer.

Your first paragraph on post 31 made me ROFL though.

Already employed
You just said same thing I did, you can use electronics and sensors to measure everything in real world. Which is why teams do have technicians at track. How many have dyno at track?
ps. there is none of this sensors on curvy.

And this thread is about Pointies... (2003 and up fuel injected SV650)

I can see people use the Flat Slides carburetors with pod filters on Curvies...

We all know how sensitive the Flat Slides can be to elevation and temperature variations...

This is not something we see on 2nd Gen SV650... A good dyno run on a hot dry day will assure a good result on an average day...

Most guys racing an SV650 do not have a team behind them...

This thread is about cam swap, remember the thing you said we can't use same marks.
You also said dyno is ultimate test which I don't agree. Ultimate test is real world conditions that can not be duplicated on dyno.
You can also run pods on pointy and gain power. Been there done that. From all the set ups you can do I had the best result with lid removed. ymmv.

LOL guys handbags down. Everyone has a differing opinion as to what works respect that please.

We have done alot of testing on various airboxes on the dyno (yes have seen a difference on all of them) and tested on track (yes have felt a difference on all of them)...we have now found what works best for us.

The funniest one which worked along with the theory I linked to was on my Ducati. Running a supposed performance air filter in the airbox with aftermarket air scoops made the bike feel on track strangled. On the dyno it lost 5bhp!. Running stock airtubes and stock filters gave the urgency back on track and the bhp back on the dyno. Strangely the fueling didnt alter much at all between the 2 but by god could you feel it!. Performance filter binned. Duke airboxes are very sensitive to volume and resonance. Yet so many duke owners wont listen and insist on if it says performance it must be better!..sometimes stock can be a better option.

What I said was that if you are to install intake cams on exhaust side, you can not use the marks on intake cams...

A Dyno gives you real numbers... Getting on your bike and going for a spin is not nearly as reliable... Dyno butt lies...

^ I would disagree on one part that riding the bike aswell as using a dyno is the best way to tell if an improvement has been made as a dyno will show fueling and power, torque and gains but riding also backs up what the dyno is telling you.

Ok just riding and not using a dyno I agree is not ideal by a long way and butt dynos do tend to lie and cant tell you that the reason the bike pulls so strong at the top end is because its pulling out of the hole you have created in the midrange LOL.
