NO SECRETS! THE TRUTH! The dyno test on the engine I built was performed by a PBM customer that does not want to be involved in this. All we want here at PBM is to give our customers a good product that performs up to there expectations.

I will compare with your specs to the Little-M only

Silicon Dart 1.270 PBM 1.630
manganese Dart 0.663 PBM 0.930
Copper Dart 0.404 PBM 0.320
Nickel Dart 0.149 PBM <0.01 which mean less then
chromium Dart 0.194 PBM 0.320
Titainium Dart 0.0058 PBM 0.052
Molybdenum Dart 0.211 PBM <0.010 which means less then
Aluminum Dart<0.003 PBM <0.010 which means less then
Vanadium Dart 0.0059 PBM <0.010 which means less then
Lead Dart <0.01 PBM <0.010 which means less then
Magnesium Dart <0.002 PBM <0.010 which means less then
Tin Dart 0.0058 PBM 0.004
Iron Dart 93.2 PBM Not mentioned


I have no record of Sulfur or Phosphorus

With no Nickel and no Molybdenium and low in copper I can't see how it would Brinell test very good but I am not a metal guy either.

I am sure there will be someone that can shed some light on these numbers.

Thanks for posting
