Dieselmax Diesel land speed done with WI

[Dieselmax]

Its a bit quiet around here,but i wanted to share something of interest about the landspeed record of the Dieselmax a few months ago. Twin 5 liter,twin turbos.
They ran special turbos @ 70psi..seventy. I was emailing the engineer and he said the only reason it could such preasure was due in part to WI. He wouldnt go into much detail,but thats what he would share.
