INFO

Designed for use with a FP RED or GT30 size turbo or larger, the Buschur Racing BF272 camshaft set delivers power without any significant idling issues. Compared to the factory camshafts, the BF272s extracted more than 110 additional horsepower from our 4G63 engine. With the BF272s, the peak power shifts from 7,000 to 8,400 RPM. These camshafts also require the installation of aftermarket valve springs. Although the power drops noticeably from 3,000 to 4,500 RPM, this loss of power may be attributed to the large runners of the aftermarket intake manifold on our test vehicle.

From 4,000 RPM to redline, the Buschur 272 cams delivered a significant increase in VE over the factory units.
