The older ti version (no carbon tip) makes more power and torque than the carbon, and won't contact the ground if you drop the bike. The chart on their site is fake. It shows the carbon makes like 65 trq! Link to comment Share on other sites More sharing options...

It's probably measured in newton-metres (nm), not lb-ft. The units are irrelevant, the gains over stock power & torque are all that matter. Don't bother looking at the peak figures on dyno charts, they're not comparable between different dynos.

It says trq. Immore interested in the curve not the peak numbers. I'm coming from a zx11 the peak on an Mt07 is invalid. 1 Link to comment Share on other sites More sharing options...

Looking st the chart from akra doesn't show the hord intake. Edited August 13, 2021 by Yamahansolo Link to comment Share on other sites More sharing options...

Looking st the chart from akra doesn't show the hord intake. I have the (early) Akra ti and Hord's airbox on my 07. Hord used the yoshimura exhaust for all of his dyno runs and testing, the charts on his website are really useful to see how different mods afected the power/torque curve. I imagine the Akra exhausts would give similar gains to the Yoshi. Yamaha FZ-07 Link to comment Share on other sites More sharing options...

Mine is Hord's PCV file. I imagine they're pretty similar. I'm planning to get mine on a dyno soon, mainly to confirm that the air fuel ratio is all good but will be interested to see what sort of power it's putting out compared to other 07s they've had on the dyno.
