My 525i is about due for an overhaul and i am thinking hey, perhaps after i pull the head etc. i should put a megasquirt on it and run LPG injectors (run lpg instead of petrol/gasoline/benzene) and run a non-intercoolered super from VF engineering like jon did.

now I know you probably think I am nuts, but lpg is over 100 octane and does cool the manifold when it goes in could be an interesting project also since you are running LPG i have it on good authority that insurance wouldn't class the supercharger as a performance modification.

Would be looking for modest power gains, looking at previous threads Jon said he ran 7 or so PSI unintercooled I would be very interested to see what kind of power he got from that. i'd like to have 250ish hp at the crank so obviously i am not going nuts here.
