the car: 2011 brembo GT, 3.55 gears
the engine: parts bin build factory boss engine with upgraded cj pulse ring, billet oil pump gears, C&L cold air, OE throttle body
ancilliary mods: kooks shortys, bbk cat deletes, gt500 mufflers, spec stage 1 clutch and aluminum flywheel, dynotech aluminum driveshaft
the tune: Adam from Revolution Auto in Rosedale, MD on a DynoJet
First, thanks Adam and crew for the most extensive dyno session i have ever witnessed! Adam perfected the tune for both the gt and boss intakes on this engine.
They had issues maxing out the MPH on the dyno in 5th gear above 7500, so I have 4th gear pulls for both manifolds as well as 5th.
5th gear GT:428/413, BOSS:426/388
4th gear GT:430/396, BOSS:441/377
the GT and BOSS were even from 2200-3000
the GT had the BOSS from 3000-5600
the GT and BOSS were even again from 5600-6600
the GT fell off after that and the BOSS held pretty steady, but showed a small hump peaking at 7600 and continued to make great power to 8200
what is clear to me is the boss mani works much better with the boss motor than the gt motor. what is also clear to me from looking at tuned coyotes is that the gt intake doesn't drop off as dramatically after peak on top of a boss engine as it does on a coyote motor. i think the gt is a solid contender for supremacy on top of a boss engine! it doesn't peak as well, but the power throughout the curve is better or equal up to 6600.
what do you think?
