Part throttle performance

[Big Lee]

Howdo folks,

If anyone has this months BiKE mag they`ve done quite an interesting article on part throttle power and torque rather than full. On the graphs it shows a marked differnce in power & torque between an `06 & `08 ZZR1400 at 40% throttle. That got me thinking of what difference exhausts and or headers would make to this as the times I use full throttle are fewer than I`d like to think
Have I killed my bikes "midrange" with a remus end can? Should I put the standard one back on & stop being a fashion victim? Get some remus headers or smash the cat out to free much more power?
I`d like to see the real gains of cans rather than an extra 2 bhp up when I reach it every now & again.

Anyway, I`m off to work now

Yep, Id be interested to see as well, look forward to seeing the results of your bikes dyno tests after you've tried all the different variations.

This was the area that I was most interested in when Dynojet used my GS as a testbed for their Powercommander. They got me a 10% improvement in performance at a 40% throttle opening & that translated into much better throttle response

No problem, if everyone would send me the different variations in exhausts I`ll do it

Good stuff Paul Did you try any variations of exhaust setup with the PC? Before/ after etc?

'fraid not... I've had a y-piece & Remus race can fitted for years, also got R1100S Boxercup inlet tubes & a K&N filter fitted - all to help the breathing.

I've just added to another thread on the site, about changing to twinspark c/heads, & I've got another little project in mind, to twinplug my single spark & give it a bit more oomph with different cams & different exhaust headers...
