    Searched, no matches...

    I'm wanting to hide all the ugly, and obviously modern, cooling nonsense on the drag truck. I'm thinking about putting the radiator, fans, and maybe even a remote pump out back in the bed area and plumbing it to the motor.
    Anyone know how this is recieved as far as NHRA tech goes?
    I'd love to be able to have no modern amenities showing...but, I need this thing to function AND I don't want to be stuck only running at nostalgia events. If any specifics are in the NHRA rulebook, I couldn't find them...
    thoughts anyone?
    thanks,
    Mark.

    Don't know about rules now,but for the drag races,or very short trips,trailer queens and show cars,rear mounted rads work,vs rear rad don't work for road cars,long runs with big hp just never git enough air no matter how u duck it,except if the rad is way over size and hp is low. HP is heat!
    I've seen a lot of rear rad's done ,some even say they work on long runs as they lie like mad.

    Not a street vehicle....drag only, that reduces my cooling needs, a bit, but: I still want cooling, I'd like to make more than 3 or 4 passes a day, with a push vehicle.

    I see no problem w/ it......As long as you do not have water,fuel or oil running through the drivers compartment and no leaks you can mount things wherever you want whether its for looks or for a functional reason..mounted well of course.......You can make it work at the Drag Strip or on the street if you want it bad enough.......Talk is just talk...experience is King.....Goodluck,Littleman...it is always good thou to talk to your local track tech guy if possible......

    I cannot speak to NHRA rules, but I did do an Opel GT drag car for a customer that runs IHRA. He wanted a rear mounted radiator for the same reasons that you do. I mounted the radiator over the rear end housing and plumbed everything along the frame rails under the floor. He has been running the car this way for 10 years with no problems getting through tech.

    There arent any rules on radiator location,, the only hiccup I can see is that you will have to run hard lines to the radiator, there is a rule on how much rubber line you can run. Most techs will let you slide, but ya never know!

    AOK for drags,one thing too look out for in the water feed lines is places that can trap air pockets. Trick being to keep high line running high but not higher then the rad or fill cap
