4BT drag car
 

Alright so im building a drag car around the P-Pumped 4bt engine. My issue is finding parts for it right now but I think ive gotten that narrowed down to a few vendors etc. But my main question is which would be better for this vehicle. It will be possibly street legal (in a few states) But I wanna know which in your opinions would be better. Running Nitrous, water-meth, or propane.

I know this is for 12 valves but there isn't a section for 8Valves unless I haven't looked hard enough

nitrous will definatly run cooler than propane and make good power

Twins and more fuel won't get you enough?

same engine just shorter block,

You can get alot of engine parts from cummins directly, but the exhaust manifold may be the trickiest since alot of the 4bts are found on tractors and generators.

Yea I was thinking of doing a custom exhaust manifold. DPP sells an exhaust manifold flange just have to add the piping myself.

I would run duals but from what ive heard 4bt's do not spool well with compounds (beans diesel tech informed me).

Consider looking here for more 4BT info: Cummins 4BT & Diesel Conversions Forums

Thank you very much
