we found that running a Bonneville was quite a challenge,over 4 thousand feet altitude and 46deg c air temp,takes a good setup bike to run fast speeds there,the first thing I did to the bike when we arrived was remove 7% fuel from the whole fuel map,this could not be foreseen setting the bike up in ...

hi all and lorcan,its been a while since i last posted on here,we built a 500cc bike last year and ran at bonneville in august at speed week,the 489cc motor was based on my fzr500 drag bike setup,we managed 203.3 average,with around 210hp,which is not bad for a 500cc non streamlined bike

it looks like a t2 garrett,not a gt,the gt series turbos have bolt on compressor housings,t series use a big "c"clip.

hi lorcan can the wolf 500 data log,as i could not see this in the specs,the ecu like it can do a lot of functions,good price against the motec.

ok i may be a bit oversized i used 5.6cc per min of fuel x hp =injector size at 100 duty cycle,yours is like 5.3cc of fuel per min x 280hp /4 injectors =371cc injectors,but thats flat out,not at say a max of 80% duty,or maybe ,are you using a rising rate fuel reg. also?,will i get my coat?

how do you work out what size injectors to run the lorcan?

i was using a set of bosch 370cc injectors on my bike last year,when doing a flyer at woodbridge,i melted one piston,when i checked the injectors thay all gave about the same flow rate,but you cant always tell if thay are working ok all the time,also my air intake temp and engine temp were a lot ...

thanks lorcan,only just catching up posts,yes i am chuffed,should go quicker yet,me hopes.

thats on my fzr not a 750t the fzr makes max torque around 9500rpm and max power around 12000rpm mine was making 100hp at just over 7500,not bad for a motor with a 40mm stroke

i machined out the exhaust housing of my garrett t2 ,to fit in a gt2065 from a saab ,worked ok had a good spread of power from 6000rpm up to 12000rpm,170hp with no intercooler at just under 30psi boost,turbine wheel is slightly bigger than the t2,and turbo spins up quicker.

i got 125hp out of my fzr500 with a t2 but you may get more on a 750t with race mode and an intercooler.

hi all you can run the 750turbo ecu upto 11500rpm then it shuts down, to go beyond this you need a
piggy back ecu like a dynojet or an earls mf2 that i used to overcome this problem.

hi all i did some flow tests on 750 and 1100 injectors this is the results at 37psi fuel presure gpz1100 175cc per min,gpz 750 210cc per min.

hi are you in the u.s or the u.k?

i agree ,i use nitrous ,so i get no lag at all,but its not the way to go on a stock motor,the smaller turbo will work better on the road bike.
