She’s a ’Runner
Blow-By Racing boosts Ford’s high-revving Boss 302 with impressive results
By Steve Turner
We love visiting performance shops. You just never know what kind of wild projects you might run into when you sneak behind that plastic chain that separates the customers from their in-progress rides. On a recent trip to South Florida we popped in on the crew at Blow-By Racing in Boca Raton. What we found on the dyno had us breaking out he camera to snap a few shots.
You might think that the owner of a Grabber Blue 2013 Boss 302 might be satisfied with the performance of his high-revving corner carver. Well, that wasn’t quite the case for Clint Bates. Not only did he want more power from his RoadRunner rocket, he mainly wanted to put that power down in a straight line.
“He wanted to build a fun, fast street car to play on the Oklahoma streets,” Blow-By Racing main man Chris Jones explained. “Also, he wants to get his wife behind the wheel and build a motor during the winter and go into the eights. More to come in a few months…”
To achieve his goals, Clint brought his Boss to BBR for a complete make over headlined by a cog-driven ProCharger F-1A. When we spotted the car it was on the lift getting tidied up before dyno-tuning commenced. We prowled around its underside, and quickly learned the car had all the support hardware to make the most of big-boost.
Underneath, Clint’s boss is bolstered by a Freddy Brown 4R70 feeding power through a PST driveshaft back to the stock 8.8-inch rear. Strange shocks, a UPR anti-roll door bar, BBR lower control arms, and a BBR Panhard bar plant that rear. A Tig-Vision five-point cage, with swing-out door bars, and Stiffler’s subframe connectors tie the chassis together.
It is definitely ready to rumble, and while we were in the shop, the car made its first dyno hits with the big ProCharger installed. Chris dialed in the tuned quickly, but the boost level was a little too high for comfort. The F-1A immediately created 20 pounds of boost. Even with C-16 race fuel in the tank, Chris believed this was a little much for the stock engine. Yes, RoadRunners are stout from the factory, but Clint was wise to plan on fortifying the engine for his future plans. In the meantime, Chris swapped on a larger blower pulley and reined the boost in at 17 psi.
“Because of the stock motor, we opted for safety and only running 15.5-16 degrees total timing and an air/fuel ratio of 11.2-11.4:1,” Chris said.
With the boost level reeled in, he could focus on dialing the car in for streetability. Yes, Clint wanted the car to maintain its dual-purpose personality, trading street and road course for street and strip.
“Tuning was pretty straight-forward on the ProCharger side. However, when going to a manual-valvebody transmission, tuning around a few things and calibrating the speed sensor can take a little longer. Overall the car drives great. It is quite streetable, and it should be a mid-9-second daily driver.”
Now you can see why we enjoy ducking under that shop chain so much. It’s not every day you see a ProCharger-blown Boss scream on the dyno. This should make one heck of a “street” car for Clint and his wife to enjoy the open roads of Oklahoma.
