Discussion
Just thought some of you drag racers might be interested in the worth of oxygenated fuel

Blimey that's a lot of ponies released there, a great experiment. It reaffirms the theory more air + fuel = more power, in this case the extra O is already in the fuel, just need to open up the jets to let more fuel in. I suppose a similar thing is injected NOS + more fuel.
I suspect the fuel is a weaker version of a full mono-propellant/fuel used in say torpedoes, where it provides not only the fuel but it's own oxegen in the liquid. Tis a bugger to put out if it catches alight though, as you can't starve it of oxegen with the usual foam blanket, cooling is the only thing that may work.
Putting my UK elf n safety hat on, is the fuel 'approved' for use at circuits/strips as I suspect they might be interested in it's burning properties, more specifically the ability to quench it once alight.

Hello David,and welcome to PH.
I tried the VP Q16 version and made an extra 150hp with twin turbos.
We increased fuel 6% but didn't touch the timing. Maybe we'd have made more if i did.
Very interesting video,thank you.
150 hp increase - good lord there are cars out there that don't even make 150!!I tried the VP Q16 version and made an extra 150hp with twin turbos.

Love to see what your motor looks like.

Car is in my profile,although that is my new one.Just click on my name and visit my garage.Or go to my website at www.redvictor1racing.co.ukLove to see what your motor looks like.

Just realised my old man used to have the ventora version of the FD victor, thought the lines under your dragster looked vaguely familiar.David Vizard said:
What can I say - i like it. looks like a nice piece of engineering from the ground up.

Thank you David.DV
A very long build thread detailing the whole build of the car from start to finish is here.

It is very long though....
Sorry for the slight hi-jack. When I was eighteen I had an old Austin 1100, and for Christmas that year I got a copy of your book on the A series motor. Regrettably I only read it before the car was pinched, but it taught me a lot. Then I saw your book on the small block Chevy, and thought 'wow, this is the first time I have heard of someone covering such a wide range of topics, from my crappy Austin right through the the drag Racing V8s.
Thanks David.
(And yes, RV 3 is a work of art, is it going to be at Autosport Andy so David can take a look?)
Thanks David.

Unfortunately no Jon. The heads,which were supposed to be ready for before Xmas aren't. This gives me no time before autosport to put it back together..Thanks David.

Well Pistonheads strikes again!
I am old enough to have raced in Minis against a forerunner of the OP Clive Trickey who died sadly very young from Asthma.
Clive Trickey was the best A series man in his time: an absolute mountain of information and ideas.
The mantle shifted quite rightly onto Mr Vizard in due course whose engineering knowledge is legendary to this day throughout the car industry.
The power output of these engines is just magnificent. Well done sir!
I am happy getting 350 BHP from my various V8 Rover based cars which is quite enough for me.
But I can only admire the knowledge, education and application that Mr Vizard demonstrates with his successes. This much knowledge takes an awful lot of effort! Much time wisely invested and a good deal of money!
I would like to see the car performing on the track. From a distance!

Not at all a fan of oxygenated fuel.
As with any time you bring in oxidizer with your fuel, you will need more fuel.
This would mean more injection capacity would be required which complicates idle fuel mixture even further because of the difficulty running an injector pulse width narrow enough for large injectors to arrive at a good idle fuel mixture.
If manufacturers are bringing in oxygenated fuel, then there must be consistency across vendors.

Just use the right fuel injectors, we do and had no issues.. As with any time you bring in oxidizer with your fuel, you will need more fuel.

I just feel it's a good way to shrink your margin of safety concerning a tune that won't suffer a detonation or leaning event that quickly destroys an engine.......because the addition of oxidizer in the fuel tipped the scales.
As far as being able to run larger and larger injectors...............
Many ECUs, even with a proper tune, won't run a pulse width narrow enough for our twin turbo ford GT (current standing mile world record holder) to idle.
