check out dylmrt's showroom thread, he has a GT3076R. I'd say you would expect peak boost around 4,250. in regards to Haltech, why dont you save the current tune and then saveas a new file and fool around with the settings?

SO... will soon have some KW V3's in it (thanks Dylmrt)
and probably some whiteline swaybars.

a set of Tein coilovers...
and a MOMO steering wheel ...the only thing actually i can see the whole time i drive my TWO....
 
just realise someone has the same combination as me.... SW20 + 600RR...

 
There's my dyno with boost graph. I have the twin scroll gt3076r which is a 0.76 housing size, but should still give a good indication of how it should spool up.

Pity that graph is in kph rather than rpm.
 
anyone know the ratios in 4th gear to work it out approximately?
 
IRRC 100km/h is about 3k rpm in 4th... i can never quite remember.

Thats because they are both fun weapons in their own right!
I shall soon be joining the CBR600 team, up from CBR250 
 
anyway...
I have roughly calculated for my Gen2 turbo in 4th gear that:
70 km/h = 2250 RPM
90 km/h = 3000 RPM
 
dunno if gen3 is any different? also wheels and tyres can affect this.

the gen3 came with different ratios to the gen2. When I get my car back i'll have to test it out again.

Nice chart!!  Dont forget the dyno would be actual KM/h (not speedo) so when checking use a GPS for better accuracy.

hmmmm for some reason i can't get my dyno graph to show.
 
however!... out of interest how many torques are you making? looks pretty flat by the boost (mines flat while boosts flat but im only at 14psi

Can't remember the Nm that its making... the dyno number for torque are always all over the place...
