I have to agree in that by pulling the exhaust gases out, the volumetric efficiency will increase.
Any ideas on a high suction / flow device that will also hold up to the exhaust temperatures? Most shop vacuums will pull less than 1 psi of vacuum and I would rather pull more than 5 psi to really see a difference.
I might be the ideal person to try this out as my car won't need an extension cord
and I don't use all of my battery pack's 2.9kwhs during my drives.
I appreciate the device tips as I sure can't find an affordable device that meets the bill!
