Air Box Mod

Inside peep for Spa man & Chriss
Re; Air box stacks I'm trying this set up next week for the Drags

Hmmmm interesting, I'm on all shorts for the time being, hiccups lower down, but nice and flat across the top end, so shift points not critical.

[simmo]

The last set up I had all shorts, I put the longer ones on the outside of the box this time as there is more air flow area there for the longer stacks.

You need a lambda sensor rob.Perhaps we could go thirds and all do some development.Combined with my veypor some good data could be coalated.

If you could tell me what a lambda sensor & a veypor is would be a good start

A lamda probe is fitted into the exhaust and analyses the gasses to arrive at an air/fuel ratio.

Need one of these or similar. The only problem is having the Bung installed on everyones bike and having a Tach Signal easily accessable

Hiya Blackzook. Is yours fixed yet?

Hi Pan, mine is running like a dream - has been ever since it was tuned by Croyden in Sydney. The only thing still to be done is to wind the boost down at the moment it's an eye opener to ride on the road.

Eye opener!


Understatement of the year award goes to Blackzook!

Hi there,

Looking at your pic Simmo, those outer bellmouths look very close to the top of the airbox housing. Is it possible that the close proximity to the top of the box could be partially restricting the flow into the throttle bodies, making the cylinders affected go rich?

Just curious, could be wrong.

[spamanglenn]

the outer most stacks are the least shrouded.The inner 2 near touch the back of the airbox on the back of the bellmouth.This is the reason for this orientation.As my dyno graph shows they do make more torque and flow better,2 factory pro longs and 2 shorts would be an interesting set up.Either way with all factory shorts simmo has seen 145mph as have I with all factory pro longs and shifting at 10000 Coil rpm not tacho rpm(approx 10400).3rd gear wheelies out of corners with stock gearing at the last track day showed me the torque increase more so than the drags.I,m guessing the above set up will be pretty good.Only an individual cylinder tune will tell the real story.

[simmo]

As Glen said there is heaps more room on the sides of the airbox, that should make it breath better thats why I did it, its all trial and error but for airflow it looks like the best set up for the longer stacks.

so it made a difference you could feel?
