Pumpgas 93 61mm 528whp Single Scroll ETS Kit!
Nice before and after results there and yes the Walbro fuel pump starts approaching it's limits at 600 crank HP. I love the turn around story going from 348 whp to 528 whp on the same dyno. Even if it's not a "low reading" dyno the changes before and after can't be denied. That's likely 110 mph trap speed potential bumped to 126 mph trap speeds and a HUGE difference although the stupid short 4th gear is going to limit some 1/4 mile numbers without some tweaks.
Should see some nice numbers with more fueling in place and higher boost.
