taking out radiator - cooling options

(1/6) > >>

FEDNV:
Since I am redoing everything on my car and running alcohol I have decided to not put my radiator back in the car.  I was planning on filling the block with water but was wondering if just using block off plates for the water pump is fine or if I should use something like this http://www.jegs.com/i/Dedenbear/302/WH2/10002/-1?parentProductId=1418208 and a remote water pump to just circulate water? 

While running alcohol I have never run my water pump until after a pass as it is fine during the burnout and staging and reaches about 160-180 and about 200 after the pass.  I also warm the car up and heat up the oil in the pits before staging.

I also got a new oil pan that has a pan heater.

thanks
Scott

Are you running a blower???

GlennLever:
I run a pump and radiator in the dragster.

If I had to do over I would mount the radiator pump and fan in the trailer in the pits and run quick disconnect hoses from the trailer to the engine when return to the pits to cool the engine down for the next round.

I have seen that setup work and it works well.

H.G. Wells:
If you are towed to the line and towed back to the pits after the run you should be fine dry. Lots of cars run water in the block and heads with no pump and it steams out as a direct loss system, this will reduce hot spots but I never liked it. Glenns thought on the trailer system would be great if you are making rounds.

FEDNV:
I do not run a blower just N/A.

I was told by the guy that does my heads not to run it dry as it will cause hot spots.

I was still going to run an overflow tank off of the normal spot on neck filler if that makes any difference.

I am towed to the line and towed back to the pits.  I run NE1 so I normally have some time between rounds for cool down.

I have an open trailer so no way I could do that radiator deal (hard enough to carry all my crap now) but I guess I could always drain it and refill with cool fresh water if needed between rounds.
