>Billhendren... please don't take this the wrong way, I am not insulting you, or the product that you suggested in any way, but I wouldn't judge an oil by what the dyno says , if I put brake fluid in a motor and it gained on a dyno doesn't mean that I would run it in my race car, what good is an extra couple of horsepower if the bearings don't live? Friends of mine and I run Brad Penn in blown alcohol and blown nitro cars with excellent results.
The question wasn't about a Blown alky or Nitro engine,it was a bracket engine. The Gibbs oil was developed for racing use only and they spent millions on it. the Nextel Cup cars run 500 miles at full throttle making 830 H.P. and have NO bearing problems.probably 60/70% of the cars run this oil.we have used it for two years in all our normally aspirated engines because our own Dyno tests showed it was superior to any dinosaur oil out there. the 2-2.5 percent gain in H.P. was from friction reduction.You would be surprised at the gain in lifespan of roller lifters.
There is nothing wrong with the Brad Penn oil especially when you throw it out every run or two in a blown alky or Nitro engine,we used it for years but time marches on,look how much computers change in three years,engines are the same,if you want to stay on top you need constant R&D and oil is a big part of it.you cant afford to give up 2 percent of your power these days.Bill
