Hi guys, this year I'm setting up to do some creative fuel experiments in my NA racing class.
I want the huge oxygen advantages of Nitromethane/Methonal blend fuels, but I don't have the cylinder pressures to make them run properly, and the combustion chamber on my heads doesn't really function well with out blocking the flamewave travel if you try to reach the pressures just through adding a massive piston dome for 18-20:1 compression.
So... doing some reading, it turns out Hydrazine does exactly what I need, destabilizes the Nitromethane to let it liberate it's oxygen and have complete combustion at lower pressures/temps.
I'm willing to have a dedicated second fueling system, and to flush everything clean after every event, yes I'm aware it destroys fuel pumps and eats alumium like candy, and I'm aware anything caustic in the fuel system results in pretty high danger levels. I'm willing to go through all the work of puttiing together a fuel system on-par with the all stainless/Titanium parts that Top-Fuel uses, and I'm willing to replace/rebuild pumps after 1-2 events.
The nitromethane is easy to source, and just 5gal will get me through a whole season. To destabilize it, I only need about ~50cc of hydrozine (non-hydrate) to do the whole batch of fuel for the season.
I guess this stuff used to be pretty easily available for racers to tinker with in adding into fuels, and a ton of records were set by using it. But it seems to have been almost universally banned in racing for various safety reasons about 15years ago, and the public availability of it seems to have dried up.
If any of you old-school hot-rodders happen to have an extra 50cc sitting on a shelf somewhere, I will gladly pay for hazmat shipping, and pay you well for the hydrazine.
Thanks!
