Horspower Depot has a Youtube channel that is really interesting.
Granted, they're racing BBC in Corvettes and a '69 Camaro in F.A.S.T. but it's super interesting to see them test and find out what works and what doesn't. Apparently sidepipes on 'Vette kill about 40 hp over rear exit exhaust! Crazy!
They've been 9.31's at 147mph in a factory appearing Corvette and 9.50's in the Camaro.
Here's a video about the Camaro where he "reveals his secrets". Have to wonder what was left out.
They are running hidden Holley EFi stuff to control timing and data log. Don't know if that alone makes them faster per-se but it does give them a better handle on their data with all the sensors. You can run whatever sensors you want with the Dominator modules - wheel sensors, driveshaft speed, etc. It all helps.
Over the summer I spoke directly with one of the more competitive F.A.S.T. racers about this idea and he basically admitted he was behind the curve without it.
I thought the electric vacuum pump he showed recently was pretty cool. You can see it in the passenger floor if you look carefully and he turns it on with the cigarette lighter knob.
