Some jb4 big turbo dyno charts!

Mike@N54Tuning.com · 02-26-2011, 02:36 PM

Just saw these customer dyno runs and thought they were worth sharing. Car is an automatic with full bolt ons, JB4, dual CM10 nozzles 95% meth, race gas (as insurance), and RB turbos. Even with the dual CM10 nozzles he is still fighting fueling problems up top. The 14.5psi run and 20psi run are targeting the same air/fuel curve but you can see at the higher boost level something just isn't keeping up. Possibly the in tank pump. Still not bad numbers. STD numbers were 1-2% lower.

Nice results! Is there a reason why so little boost is pushed down low?

Fueling problems. These turbos would probably hold 22psi from 2500rpm to 7000rpm if we could get enough fuel in there to support it.
