Supercharged Project

[ben11]

Hi all

I am in the middle of building a puma 1.7 powered fiesta with a supercharger. I have been talking to a guy who has said with the bottom crank pulley not having a keyway there is a chance that it could move nocking the timing out?? what are peoples thoughts and do you agree.

i am only aiming at running 7-9psi and 160-180bhp maby 200bhp if i am very lucky.

:lol: it is a funny system... but unlikely, if it's torqued up correctly.. 40nm + 90deg

I tend to clean off the bolt and also clean off the mating face of the bottom pulley with a fine paper so that it grips well

Im sure you can get it keyed somehow

Sorry for the late reply. According to this graph the power consumption of a m62 running appr. 7.5psi and 10K RPM should be appr. 17bhp.

If I remember correctly the A/C that is normally where the supercharger usually goes drains about 10-15bhp. I don't think that the difference is too great to cause problems. (I hope so because I have the same plans for my car).

If you have the time please do a project thread because there are not a lot of supercharged 1.7s and I think it would be a nice solution for more power.

Youll get more than 200bhp on an M62 if you thrash it and let it produce decent boost. StuMC on here got his to 170bhp on an M45 on standard compression poorly running.
