I think we invented the "dial a boost" back in '77. We had a customers car come in witha Fairbanks TH400 and a "dial a shift".This varied the amount of vacuum applied to the modulator to change shift "feel". We got the idea to apply this to the unused port in the (then new) Deltagate. Dial a boost was born. Were we first? I dont know , but there weren't a lot of CO's in the turbo biz back then.
Fuel pumps: We used the Holley "blue" with the Moroso "high pressure spring" which boosted the pressure to 20 psi, enableing boost pressures of 10-12 psi. At that time we retained the boost compensated mechanical pump which was much more reliable than the Holley elec. and came up with an elec.pump automatic bypass device so that the elec. pump would not have to run full time.
