By popular demand, we are dedicating a page aimed to share all of the build specs and products used on our 2022 Camaro ZL1 1LE test mule. Our goals for this car were simple. Find ways to maximize the 1.7L blower with Di fueling only, for a low boost fun street car… which I think we achieved as we recently made 915rwhp and 850rwtq on only 15psi of boost and E60 blend. Because this car is being wrenched on constantly testing products, and configurations… the list below may not be 100% current all the time. Any questions on the stuff we have, or wanna know what we have tried? feel free to email us at info@griffin-motorsports.com. We would be happy to help you learn from our mistakes, and help you spec your build from mild to wild.

Factory 1.7L Blowers suck…
Until you have it ported, install it on a motor made more efficient using ported heads and an efficient camshaft. With the right fuel system and supporting mods it’s doesn’t even take much boost to pass the 900rwhp on only 15psi of boost, and an upgraded Di fuel system. No Meth, No Port, No 2650. Just instant torque and a blower whine that can make a grown man cry.
