The Forced Performance "Big 28" - This may well be the ultimate autocross turbo, and may wind up being the ultimate 2G drag upgrade turbo too. Still in the design stages, this turbo is also based on the T25 core, with a T28 turbine section. However, it has a 520 CFM @ 15psi compressor wheel that outflows (and is more efficient at high boost levels too) than the mighty 16G! Faster spool and more power.
And as it turns out, the Big 28 absolutely kicks ass. It spools almost as fast as the T25 did, and pulls hard through the entire rev range, maintaining over 20 PSI all the way to the limiter. This is the turbo for an SM car.
Hey, we won a ProSolo Championship with this turbo - it works.
