Pre Turbo Methanol injection.

[BlackFastRT]

Are you serious... this method isn't sprayed into the turbo but on the turbo... which makes the heat disapate quicker so it creates a colder air charge...

WTF? Read the thread?

Why would you spray the turbo housing with methanol?!?

[Ondontii]

Um, He said spraying methanol, not water.

Aquamist is just a "brand" of nozzle that he says is high quality.

Draw through carb turbo setups have proven themselves to be great performers and I believe they were often superior to blow through setups in the past 70 years or so.

The reason people avoid draw through has nothing to do with the turbocharger being damaged and everything to do with ice forming in the carburator. Not a good choice for daily driven cars.

And he is talking about spraying a small amount of fuel into his turbo, not 500-1000 hp worth of fuel.

Draw through carb turbo cars running circuits for hundreds of miles or even endurance races in the past put more of a beating on the turbo in one race then you could hope to accomplish in multiple lifetimes of normal driving with boost.

If draw through carb setups really ate up the compressor wheel, they would never have won a long distance race because they would be down on power at the end.

Now, not running a filter on your turbo........yes, that is stupid and you will ruin your turbo and your motor will be hurting. (some drag cars can get away without a filter but if you plan on driving more then 10 miles a year in your car, be smart)
-Yes and my pictures below make me look like a bad guy because the filter is not installed but I have one! Just doesnt look neato for pictures :P

I will be using 3 spray nozzles...spraying a small one into the turbine outlet and then 2 others about 2 feet before the TB. My only worry was about fuel puddling in the intercooler if the intercooler was working too well (if that were even possible). My front mount seems more likely to have that problem BUT I would bet that I am just being paranoid and it would not actually happen even if I sprayed a lot of meth into the turbo inlet.

I`ll be using a 0.3mm jet per turbo which equates to 100ml/min for each of them, the jet holders will be butted up to the inlet of the turbos.

My mix at the moment is 75% methanol 25% water, the air displaced by the injection is miniscule compared to the amount of air entering the turbo.

I have seen pics of compressor damage, unfortunately nearly all the cars also ran no air filters, I understand there`s a risk of pitting the compressor blade edges so I`ll take some before and after pics as I go.

At the end of the day it`s an experiment, and the car won`t be on 9b`s for ever but I`d like to see first hand if there are any gains to be had.

If I can gain 2 to 3 psi of boost to redline with minimal wear I think it`s a worthwhile exercise, if not I can just take it out again..

So do we have any results yet?

[keithmac]

Not yet, got all the bits just have to build my jet holders and plumb it in. Will do some road logging to see if it holds more boost in the higher revs but I can`t do any 1/4 mile runs until the track opens again next year.

Will keep you all updated as I go.

I'm interested to see how this turns out. From what I've read, moving methanol (turbulance) causes it to evaporate and get really cold, I've seen this on a blown alky drag car that I pit for, sprayed before the blower, and the blower actually gets ice cold from whipping it around.

But turboglossary.com or something like that, used to have a turbo calculator that and apparently they measured in three places before the turbo, before the IC, then before the TB, and they claimed that before the TB had the best results.

forgive me for my lack of knowledge, but would this be the same as spraying the IC with NO2?

Read the thread. inlet of turbo = what (air/fuel/dirt/rocks/sunshine) goes into the motor.

Sorry I did not make my self clear. I was reading that people use No2 to freeze the IC which in turn decreses the Air temp inside the IC.
