Yes, only 3rd. This is the weakness part of gearbox.mx3matt wrote:you only have a straight cut 3rd gear?



Of course, standard pulley will rotate about 8,5k rpm (aprox. preassure 0.3bar) . I`ll use a 58mm pulley which gives 14-14,5k rpm which is nominal speed of Eaton M62 (aprox. pressure 0,7-0,75bar).Josh wrote:Nice, I cannot wait to see this put together.
Are you planning on eliminating the clutch and going for a smaller pulley?
Nice, are you going to be running some kind of waist gate as to not run full time boost? I have been researching the 62 and the 90 and seems the 62 with the smaller standard size pulley is the best option. But I want to save a little fuel economy while driving so I have been looking into incorporating a waist gate to help releave some of the boost under normal driving.weede_klze wrote:Of course, standard pulley will rotate about 8,5k rpm (aprox. preassure 0.3bar) .

14,9 but my engine doesn`t generate full power, only 180 hpIMACHU2 wrote:You never mentioned your 1/4 mile time at the meet???
Waste gate is used with turbo systems, not supercharger - I will have full linear boost from low rpm. I`ll use bov to open intake when throttle is close. Thats itJosh wrote:Nice, are you going to be running some kind of waist gate as to not run full time boost?
hmm, that was my first initial thought, but then I started looking at like the 62 out of the Cobalt and a couple of others, and they have a regulator valve to keep boost levels low during normal driving. a similar valve would be like a waist gate, and you could plumb it in a such a way to do the same thing or act in the same way. I know there is not much room to mount a colbalt M62 int he AC location so I was just looking into other options for like benefits.weede_klze wrote:Waste gate is used with turbo systems, not supercharger - I will have full linear boost from low rpm.

In your case the best solution is clutched SC - normal, economy drive you simply dont use it. But you must have MAP sensor in intake manifold to control the pressure with mapped ECU.
