A little 5862 vs. 6465 twin scroll spool data

Hey guys,

For kicks we swapped the 5862 Precision turbo on our FFTEC 135i top mount twin scroll over to a 6465 Comp turbo. The new turbo should support another 75whp to get this car up closer to 700rwp.

But in the mean time I was able to do a quick spool test. At 3300rpm the 5862 hits the ~17psi target. But the 6465 takes another 500rpm to get there. At 3300rpm it's at ~13psi. Not bad considering our 6466 bottom mount makes almost no boost at 3300rpm. We'll find out if the extra lag is worth it on the dyno next week. Click here to enlarge
