Nos51 & Acrite(big names in the K series world) from Florida recently broke their own record of 742whp/487wtq on 30psi on STOCK K20 2.0L sleeves. That set-up went 9.94 @ 153mph.
They just recently made 885whp/586wtq on 39psi tapering to 37psi on STOCK 2.0L sleeves and “pump gas”…E85. They’re switching intake manifolds and some bigger injectors(they’re maxing out the 1600cc’s now) and going to do 900+whp on stock 2.0L sleeves.
Here’s the car & dyno graphs:
