Yeah, I used to work for Airsensors, the company that originally made the castings and electronics back in the late 1980s. It will make your car go fast with an extra 1000 rpm to boot on a stock L98.

Sounds nice.

Would be nice is someone made an LS style manifold for the L-98.

Sure looks like a good setup. Those runners are huge, and I can only assume the base is matched to them.

The runners had a 30% increase in flow over stock and the throttle body was 1000CMF. I only drove the cars to develop the software for the controller and I remember 1000 rpm increase from back then, 18 years ago. Thats 1000 above the 4500 rpm peak HP of the 1988 L98 TPI corvette.

BadSS knows a bit about them. He participates over on 3rdGen.
german-motorsport is another member there with some knowledge about these.


There is a new "TPI" intake on the market, It's called the "FIRST".
