some pics Some Turbo questions posed by ST lister Martin Retherford and answers from Brian at Turbo Connection. Question 1: Can you find out the process for setup. I was reading something and if I remember correctly someone setup a 595 with a turbo and an extra set of fuel injection with no other work and it runs. This goes against every concept of what a turbo is in my experience. Answer: The only addition to the fuel injection is our supplemental boost computer, which is run in conjunction with the stock Triumph computer. Question 2:Small displacement motors generally require some engine disassembly, combustion chamber reshape/compression reduction (especially 11.2 : 1 ratio), and special lump stick. These are the absolute minimums to run a turbo. Answer: By using a intercooler and keeping the boost levels below 8 psi in our kit we are able to leave the motor stock. Question 3:It may also require new rods / crank possibly specialty pistons and if you're really going for it, porting of the head. Answer: The Triumph motors are built plenty strong enough for these boost levels. Question 4: What boost is this thing running at? Answer: 6 psi on low 8 psi on high Question 5: Without a compression reduction it should be guzzling 92 octane or running on aircraft fuel 120 ctane + or maybe alcohol. On normal water cooled motors as a general rule 9-15 lbs. boost is about all you can get out >without pinging/detonation problems. Its no more than 9 lbs. boost for air cooled motors without special fuel. Answer:92 is definitely recommended and higher octane is recommended if prolonged high boost wide open throttle blasts are done. Question 6: It is possible to run a turbo with 11.2:1 ratio if you retard the timing way back. But I don't know if the ST can be manipulated like that. Answer: The timing for the these motors has not proved to be too excessive. If you have any questions, please email Brian for more information. ** Also ** SuperBike did a review (Oct99) of this bike - Click here to read it now Motorcyclist did a review (Jan00) of this bike - Click here to read it now |
