Quote from: gillard28;504160Sure Rich.

The problem is the atomisation of the droplet. If you spray it from where Ross is the droplets clump together. the larger sized droplet causes the impellor to chip and errode.

You need very fine atmoisation and the ratio needs to be finely worked out.

I have done this in tha past with great success. To name one, high compression rotors running high boost.
S

p.s its not going to unballance anything if done correctly and is not going to do anything to his intercooler becasue he dont have one.

With the meth he will gain loads by having extra ignition advance etc

Dear oh dear my efforts are really underestimated. But dont underestimate holding together an engine on PUMP FUEL at 1.9 BAR with 70 degree + intake temps, with a 1000 HP turbo.
PS, I believe you are mistaken as to where I am spraying it, I think you are confusing a push fitting that allows intake removal for a jet.

What happened to your wee beastie yesterday Ross ??

Are you spraying it onto the nut on the compressor Ross, or completely away eg opposite direction away from the turbo inlet and letting the pressure differential caused by the turbo to suck the water mist in?

Dont worry if you cant devulge all your secrets on here, I understandy :Thumbs-up

Rice Racing in Oz has done pre turbo WI many times with good results, never seen any broken blade eveidence before. location and direction of the jet is key

What ever really. I was just trying to help you out but you seem to know the lot. Best of luck.

When I was looking at the car i thought that it the water metanaol was getting sprayed into the plenium . Guess the debate is if the water/methanol injection is going in preturbo or not. Wouldent have thought so but i may be wrong.

Id be very warey of water droplets going into the turbo. Ive seen at first hand the damage a blade of sand strikeing the titanium blades on jet engine can cause and would have thought the effects would be similar..

Quote from: DRAGON;504485Jon if you actually had a clue what you were talking about I would be prepared to have a discussion with you. But as you just regurgitate what out dated or biased information youve heard I have no interest in responding to you.

...responded Ross. :Giggle

Ross - looks very interesting, no I/C seems to be a very brave move but if it works and the engine holds together then it\'s great. Clearly good to use this in appropriate applications though.

Would I be right in guessing that, for longer runs then Time Attack, an I/C would be needed or are you able to do 10+ laps without giving the car a breather?

He\'s not the first person to try that though. Tims been running his FB without an intercooler for ages.

Yes it is a the debate on pre turbo WI,
Just a thought to mull over in terms of water when a jet plane is travelling fast through rain, does damage occurs to compressor blades or does it occur over time?, a question to you aviation engineer guys I know a few are on this forum
I will have to look into when WI was used in WWII fighter planes did they spray directly into the supercharger/turbo or post charger

Dont be so sensitive. I just told you that you are mistaken as to where I have the jet. And I far form know the lot. If you\'ve got any advice or suggestions then im more than happy to take them on board.

Blimey, all a bit warm here...

Well, I think it\'s cool to be trying something a little different to what I\'ve expected. If it works, then WINNER!! I\'m certainly keen to hear the results, and see what the long term effect is on the components.

I\'m a big fan of different things being tried and tested - in Practical Performance Car mag, the cover car has a turbo in place of the rear silencer... and it works fine apparently. (athough I love their Rolls Royce track day car with the truck turbo. Or the SD1 Rover with the 27 litre tank engine).

I\'m not suggesting that Ross hasn\'t considered and thought about what he\'s doing, and I\'d like to think that we\'ll see the results of these ideas shared about... After all, if it wasn\'t for people thinking out of the box, dear old Felix might never have come up with our fave power plant!! And god bless Mazda for sticking with it!!

Now a Datsun 240Z with a naturally aspirated Bridgeported 20B would peak my interest....

but you can\'t have a 240z without a straight 6!

anyhoo, back to the topic:
I think this has been asked, but how long can you run a car at high revs using WI (well ok Methanol) instead of an IC or is it down to the reserves of Methanol you carry on board?

Maybe, but you wanna see the rascal go ferreting!!! Need a bigger pooper scooper tho... *grin*

PPC is one of the best mags out there

Also, congratulations Bish on a well exectuted thread hijack. :yes
