Since you already have nozzles, and are on your way to Nobels price in research, you might want to try Hydrogen Peroxide(H2O2) in approx 30% concentration. If memory serves me right, it transit into H2O+O at 4-500°C, this requires energy, lowering the temperature, and on top of that you have added an extra O in liquid form(= very dense = just about no of the normal air is displaced = more air at ignition). I'm not sure if the alloys will be able to take H2O2, as it's very reactive with some.

I wouldn't really do that if I were you, peroxide produces its own heat as it decomposes in fact it tends to explode and this will add to the shock and induce wear on the engine also if the peroxide is decomposed before going into the engine the water vapor and oxygen will be very hot and thus take up a lot of space and not very much could get into the chamber at a time and the amount it heats up upon reacting with the fuel wont be as dramatic and so the power would be low.

Good to hear you are enjoying your setup. Must be the definition of well deserved! Would really like to join for a ride, but 17624km says no.....

Brett,
So, is the whip down for upgrades...the turbine upgrade If so, how's it going? Curious what was the negative result of earlier swapping to the smaller AR housing. Obviously you're looking for improvements from a larger AR...what target objectives do you have in mind in terms of boost threshold, spool dynamics, top end

The dynamics of my manifold design work in mysterious ways and it took me a long time to understand it . When I tried the smaller AR the minimal effect on spoolup was offset by lower torque , so I got less power per psi at both low rpm and high rpm.
With the larger AR I'm hoping for a small reduction in spoolup (14psi by 4000rpm vs current 3800) without a corresponding drop in torque. Up top I'm hoping to see the maf peak rpm go up 200-300 rpm which should give me an extra 20-30whp. All the other 'upgrades' I've done have had the effect of putting more air through the wastegate and moving the maf peak rpm down (producing the same whp but at a lower rpm) . Getting more air through the turbine SHOULD have the opposite effect . Fingers crossed.
As to why that happens ..... my theory is that the path through the manifold tubes that feed the turbine is way less restrictive/turbulent than that through the wastegate , so more air through the turbine is always going to be more efficient and make more power than more through the wastegate.

Just gunna park this here for future reference . Good info on Intercooler core design !

But per Stroker's comment... did you experiment w/ increasing boost &/or timing while running W/M? If so, what were the results of your experimentation w/ W/M injection combined w/ increased boost &/or timing?

Then your testing did not rule out power gains d/t increased timing or boost while injecting W/M for those with MAF headroom under the 400 HP level.

If you are referring to my 'ceiling' theory ....then yes of course it's still a theory . That test was never trying to prove or disprove it so not sure why you would say that .....

Know of anyone who has successfully run it?
#1873
I'm investigating W/M injection vs. Ethanol mixing. W/M is attractive..., the thermodynamic theory is sound, but haven't found anyone to successfully run it on a Renesis. I'm wondering if the labyrinth of long and winding passage ways in our UIM/LIMs prohibit successful application.
Lot's of people run it ........... whether it is actually saving their engines ...I don't know.

If we want to be completely technical/scientific, it is not a scientific theory until it is proven and can be repeatedly tested and confirmed, until then it is just a hypothesis...
No I have nothing productive to add to this conversation.

It's actually closer to a theory by that definition RMRx . It has been repeatedly tested by quite a few people that have tried to make big power on a Renesis and failed. I would venture to say ......it's been tried more times than we all think it has. But no-one likes to admit failure so we never find out about most of them.
