Straight LPG... much higher octane, vapor fuel... to me it solved all the problems w/turbos.
Mine has not been really road tested.... I have spent the last 2 months building it, and I am just getting to the road testing phase.
I have discovered this....
1- My engine seems to be pretty doggy on the bottom end(up to 15 mph) this may go away with more tuning.
2- When the needle on the boost gauge hits 4 psi start holding on, cause past 5.....lest just say that 20-75 happens quick
3- I like propane. The system is just so simple and foolproof. But time will tell.
4- One of two things happen when you tell someone about a project like this either; they just walk away slowly and think that you are completly mad, or they just say that you are a total moron and that will never work. My neighbor is the latter... he just shakes his head as I go by with a full on F-16 whine.
