Cooling
dusterdave173:
I start my car in pits and get a little heat in the engine--I drive to staging and shut off --I make my run and can drive back to the pits--When alky is at idle you are rich so it is COOL--when you stomp it--thing goes lean and temp builds during run until you close the throttle, then back to rich and major cooling If you learn all the tricks with fuel shut off you can build heat easy when needed and also using correct shutoff procedure ensure it will fire right back up usually without a prime--most primer systems sold use the cheapo electric pump from auto parts ebay and it is a sorry piece of junk though those kits may be sold for couple hundo--a squirt bottle is all you need --you are show racing--you have time--if you want to bracket race then that is a whole different kettle of fish--sure 180-200 runs faster than 150 at the line but ain't that big a deal unless you are real racing and need that extra--sure! you need good heat to be safe for the engine but again not that big a deal. Yes you MUST drain system when you get home from wk end of running--you develop a routine and it becomes second nature--easy as pie--gives you a chance to go over everything and get to know your car. An old dragster with a radiator just looks wrong to me , same goes with a carb--take your time do it right the first time Help is all around you--several of us run near you Good Luck!

I do understand the benefits of running alky. That is the reason for planning to do the switch. But my plan for now is to get it to the track before the end of the year and make a few passes and try to see what I need to address before racing begins in the spring. I had the intake carb, and water pump laying around, so really just need to add a radiator to be gas ready. Injection just isn't in the budget, with all the other things I need to do to get it race ready, if I'm going to run it before winter. I do appreciate all the offers to help with the tuning of the injection when the time comes, I may need a little bit. My one alky car was blown injected but it was close to 15 years ago, so I'm sure I will be very rusty tuning. But most of what goes on in my area is bracket stuff anyhow, so if I'm gonna run more than a couple times a year, a cooling system will probably still need to be in place

VW Rabbit radiator here. 12"x 24" two 10" fans sitting on top sucking the air through. Stock aluminum water pump with electric moroso type motor. We run a BBC on gas in Las Vegas, running in two bracket classes super pro & pro each event.
We always run the water pump and fans. Stage at 170. Drive back to pits 180-190. When we start hot lapping in the heat in booth classes, we put the charger on and run the water pump between rounds to cool it.
crider:
Thanks Scott. How many cubic inches?
