top end lube

(1/3) > >>

hemidakota:
So does everyone run top lube? We went testing this weekend and slowed down .45 on et and 11 mph. The problem I think could be in the top lube. We have been running M5(with no top lube, is premixed) for a while and really like it except for cost. So to make a long story short engine is also fresh, only changed compression to a little higher and now have a mag. Other than that all is the same except for the fuel. We had a friend recommend blendzall gold for a top lube so we tried it. Called blendzall and their tech dept. said to add 1 pint to every 3 gallons. So it seems odd to add so much? So 1 1/2 pints into a 5 gallon jug of M1. We only made 3 passes one of which did not get a time slip. so only two time slips. Down low fed is pretty good. by 1/8 mile it starts to slow just a tad. on the big end it lays over. My thought is the top lube just makes the fuel too thick and being n/a our nozzles are pretty small. Or the mag has a problem. I just don't see tune up changing that much due to fresh motor. And tune up did not respond to changes like it always has. So before I ramble for hours Ill stop here and see what kind of input or questions. And yes everything has been double and triple checked. and no we do not have any data system...A lot of people have told me not to run a top lube also?

digster:
Seems like a lot of top lube. I use Klotz top lube 1 qt. to 55 gallons Methanol

Totally T:
Im on Klotz and its two cap fulls to 5 gallon.

ricardo1967:
Can you guys tell any difference of using Klotz lube at 1:220 ratio? Is it really needed? There are millions of passengers car in Brazil fueled by 100% ethanol, lube-free.

Has anybody ever thought of using 2-stroke oil for methanol?

George:
I run no lube in my fuel. I do lube the blower strips before every race.
