Fwiw 900 rwhp is what, 100 lb/min airflow?

Assuming e85 with a stoich is 9.8/1 and a wot lambda is .82 you’d need 746 lb/hr fuel flow. At 22 volts a single dw400 w/ check valve, stock siphon system, stock bucket, and stock line will flow that sustaining 55-60 psi. That’s about all it will do though…

yes 900 wheel is ~ 100 lb/min airflow.
I thought he would need something like 500 LPH.
746 is something ~460LPH

E85 could be as much as 10% more dense than gas, which works to your advantage. Wonder if that’s the discrepancy.

He mentioned it in his lastest video about swapping.
I’d like to know how he has the DW810 set up ? He has now change from a fore system due to fuel problems and now running a single dw810. I think he is around 1000 rwhp.

 

[Timbuck]

he is running a return system with the standard dw810 kit with 2 speed controller (hobs controlled) 1/2 speed , full speed…. In a radium bucket.
