Q: What's the difference between Blue Thunder Sport Formula and
A: Blue Thunder Sport Formula features a unique additive called
ZX-7, that provides over-lean indication/ protection. When an engine is
over-leaned, internal engine temperatures dramatically increase. At these
critical temperatures, the ZX-7 in Blue Thunder Sport Formula actually
changes from a lubricant to a combustible, giving an immediate indication
to the driver that the mixture is too lean. On the track, if the engine
is over-leaned, the driver will immediately notice that the car hesitates
during acceleration, indicating that it's time to pull in and richen the
mixture. If the engine is continued to run at these over-lean settings,
it will quit before damage to internal engine components occur.
Blue Thunder Race Formula features a caster-base oil package that utilizes
the highest purity caster oil, combined with a small percentage of a synthetic
additive, to reduce carbon buildup. Caster offers maximum engine protection
under the highest stress and heat conditions. Blue Thunder Race Formula
allows the broadest possible tuning range. This allows engines to be tuned
beyond peak lean settings for maximum performance and fuel economy, while
preventing engine over-lean sagging/bogging.
Q: Which Blue Thunder Formula is right for me?
A: Blue Thunder Sport Formula is ideal for those who are new to
gas cars or for drivers who want maximum protection for their engines.
It prevents engine damage due to unknowingly running an engine over-lean.
This is especially important for your first time nitro users.
Blue Thunder Race Formula is blended for racers who want maximum performance
from their engine. In order to extract every last bit of power and fuel
economy from an engine, this is the best choice.
Q: Why is Blue Thunder blue? When I take my engine apart, sometime
the internal parts are blue. Is this a problem?
A: A small amount of blue dye is added to Blue Thunder to make
it more visible. Fuel's natural color is of weak tea (transparent brown)
and is difficult to see in your car's fuel tank. The blue die is added
to make it easier to see the fuel level in the tank. Plus, when doing
quick pit stops, it makes it easier to verify when the tank is completely
filled. The blue dye molecularly attaches to the oil in Blue Thunder.
When disassembling an engine, a blue tint indicates a concentration where
oil has been. The blue can easily be wiped off with a clean rag or cotton
Q: Blue Thunder is offered in 10, 20, 30 and 40%. What is the difference
and which should I use?
A: These percentages refer to the Nitromethane content. Nitromethane
is an oxygenator and can significantly boost engine power. It's much like
raising the octane in the gas in your full-scale car, but nitro has an
even greater effect. The most popular nitro by far is 20% and we'd recommend
this amount for nearly every application. When the traction comes up with
4WD on-road cars and the track is big, stepping up to 30 and even 40%
is common practice. On slippery tracks use 10% for better control. Blue
Thunder is specially blended so that changing from one nitro content to
another has minimal effect on engine tuning. You can usually make nitro
changes without having to re-tune your engine.
