Re: Reid vapor pressure
I always forget about RVI. It was either high and now it's low or else it was low and now it's high. Whatever or better, whichever way it went is irrevelant. Todays gas will percolate much more quickly. Pre-percolation or boiling off the aeromatics (cooking) will make the gas more like it was in the 60's and hence less likely to cause partial vapor lock in the spyder. Yes, there's an idle air bypass on the FI and an idle bleed orifice as well. The idle line pressure is low, compounding the problem of smooth idle. I used an all aluminum 400 cu in sprint car engine in my 62 for years and needless to say the engine compartment was very hot all the time. I had a problema grande till I figgered out what was happening.
