Inliners International Forums General Discussion Blown and Injected Hacking together EFI on an Pontiac OHC Six

Those Gtech's & smart phone apps for estimating HP, 60 ft 1/8, 1/4 mile HP etc are pretty good.

I have a Belltronics Vector FX2 https://www.youtube.com/watch?v=AqaOOD8U5tE & it is pretty accurate. Timed my car on the street then went to a track & was pretty much dead on.
