I'm currently watching Spike TV and there's this car show,
I'm not sure if it's Car and Driver or another show, I wasn't paying attention.
In any case, they're installing a Propane System along with a NOS System on a Diesel Engine Truck...
I never knew that you could put NOS on a Diesel truck...
But apparently it works...
Check out the site above... although most of the applications are for USDM Diesel trucks. And I believe a VW.
They were also using a 4" Exhaust pipe with a 5" Polished Muffler...
Now they're putting in a ECU add on ...
(btw... this is a normal everyday truck... not a racing truck on anything...)
Original = 294 hp (no mods)
1st Run... Propane only = 421 hp
2nd run ... w/ NOS = 455.1 hp over 480 pounds of torque...
