how old is your radiator also what your timing set at? any chance of a vacume leak somewhere? use some wd40 and spray around the intake and base of carb and see if it revs up at all

There are a million questions I could ask so I will start here and see if I can help you. I didnt here any thing about a fan shroud that is a major plus having a really good fan shroud.I would still jet up the carb since your running on alky that will always help and wont kill your performance. If you think of anything else let us know....Towman

1 to 1 would be same size pulleys

just a thought, but on my buddies b-mod the first year he had about the same problem (running gas though) after he chased this for about 4-5 weeks we noticed that at speed down the straights the plastic he had on his nose piece was folding down and almost dragging on the track. it was cutting off the air flow under the front of the car to the radiator. we trimmed that off that night and instantly lost 30 degrees on the water.

If you mounted that plastic back farther and it guided the air up through the radiator it would help even more.

The larger crank pulley would speed up the water pump. Something to keep in mind is that all water pumps are not equal. Some just do not perform well when turned faster than say 5000rpm. Get a water pump designed for racing and higher rpm effeciency if you havent already.

Is you lower radiator hose sucking shut? make sure it has a spring inside the hose. Make sure your radiator fill cap is the highest point of the entire cooling system.

Have a couple of comments for you. We run 1:1 on our water pump to crank belts, further we run 2 belts. NOticed some time ago that there was excess slipage if we ran a single belt over the water pump and then over tot he power steering. Double grip notch belts are definately appropriate here. BEWARE, if you want to run the D&M or Speedway front mounted water pump drive on your KSE pump. KSE only wants the pump to operate at 50% of crank speed. The standard kit is designed for 30% reduction pulleys. If you want a drive for the 1:1 thing let me know. We run a 140 pill in our KSE for Alky and finally, we do not run a restrictor of any type in our water pumps. More water flow is ALWAYS better. If you want some technical resource for these items you should go to STEWART components website for racing water pumps. I think you will find this information very consistant with their requirements. By the way use a 4 blade Deep pitch STEEL fan and when you go onto gas use a shroud.
