Do you allky guys run radiator fans?

Like it says. I have a 89 ranger 408w. Went to allky and blew head gasket. Was thinking when putting the radiator back in leaving the fan off. Heard of people not running them and not running radiators all together.

Thanks for your reply, I normally like to make a pass at 140-145 when I ran 110 gas it would get up to 170-180 coming back to the trailer. I have an electric fan to which I leave running till it cools back donwn. Now havent got to make a full pass with allky. But it can set there for 8-10 mins without the fan on to get up to 170. So I think it would be fine.

I run 150 at the line with the electric water pump and fan on. Go thru the traps at around 160 deg. by the time I idle back to my pit its back down to 150.

Do you run alcohol or gas?

Yes running a BG400 pump rear mounted. I blew a head gasket first try at a pass. Think I did it on first crank up switching fuels. Bad back fire caught the headers on fire, when I first turning the pump on I guess their was a spike in pressure and the rear bowl sprayed a lot. I am fixing to put motor back in hope to run it agian this weekend. Best it has ran was a 6.49 at 106 1.45 60ft. Put new tires on, changed gear from 4.56 to 5.14, and changed to allky. Hope some 6.20's

All the people I know that run allky do have belt pumps and front mount. One has a front mount and rear cell. What kind of pressure do you run at carb and pump?

Are you bracket racing?

Put a fan on the radiator. Consistent temps can and will help your overall consistency...and not just coolan temp. Oil temp and trans temp play a huge role (especially trans temp) in consistency. My stall speed at 120 deg is 5700. At 200 deg, it increases to 5900 give or take about 50 RPM (on the datalogger). Higher oil temp means slightly more HP due to less drag BUT too much oil temp is obviously not good. Gotta watch oil temp with alky-it will get up there but coolant temp can still be "ice cold". I've seen my oil temp get up around 220-240 with coolant temp stuck on 130.

I also have a front mount cell and belt pump. The only way to run alky, IMO. I also now idle on gas rather than on alky-which saves a TON of fuel and warms the engine in no time flat. Oil lasts all season too without changing it. Idles on 93 octane.

I also have an '84 coupe that used to run rear cell and alky carb. Fuel pressure always drops at the end of a run. A1000 pump. I'm at 1-2 psi at the 1000' finish line. Since it mostly ran 1/8 mile, I didn't worry with it too much. The cell feeds into a single 10an line, then to the pump, same 10an size line which runs up to the carb and to a home made log with a return style regulator on back (Mallory 4309, which BTW works GREAT for alky-hook the boost reference to the manifold vacuum fitting....1 psi at idle under vacuum and with no vacuum it goes up to 8-9) and an 8an back to the cell. I've since added a front mount cell and believe it or not, a holley black pump. Same 10 an line feeding the log, reg on back (after the carb) and a single 8an return. Pressure never drops unless there is vacuum on the regulator.

Friend of mine tried a BG400 in the rear, a similar setup as yours. Granted his was a pretty hot BBchevy (about 850 HP) but it never did feed the carb enough fuel. He switched to a front mount cell and the problem went away and consistency came back. Runs 5.62 all day long in almost any weather. He's got his game together. Too bad his health isn't good.

As far as running no radiator, that's best left for the aluminum block guys with dragsters that have plenty of air circulating around the engine. For those of us with cast iron blocks and/or concrete, because of the heat retention characteristics, it would be best to retain some sort of radiator, if for nothing else, to keep the coolant temp regulated. Or find yourself a billet block and forget about a cooling system altogether
