has anyone tried this pre turbo water injection idea? got any logs or data from it? i have heard some VERY intresting things about it. sounds like you have to make sure you run LOTS of presure and spray as fine as you can.

Anyone got any coments??

Also could water bve injected before a centri SC???

Cheers,

Chris.

I would think that that would work better on the centri to keep the actual blower temp down. On a turbo, I was under the impression that you want it hot.

The idea is that as water has a very high specific heat capacity when the air is compressed in the turbo (not seen it in a SC) the water helps absorb some heat. this results in lover temps after the turbo. also the turbo work more efficently.

ye you do want heat in the turbo but not the comp housing..if you spray some gas/meth water mix it will do some crazy cooling for the better.. kinda like a draw/pull thru turbo set up. its nice to see the intake frost up on a 95 degree day with 80+humid day.like sub 30 deg intake temps cold and dense. some people will say it will hurt the turbo but i have run a turbo for 4 plus years with a draw thru setup on it and it had tons of fuel run thru it over the years so good luck with it ..

i have done it, i ran a single M5 nozzle about 4" before the turbo and 2 M10 nozzles a the TB. I was running around 30psi with the dual setup, and when i added the M5 i saw my inlet temps go from about 5* over ambient to 10-15* below ambient. I also went up to 32-33psi as i was maxing out the turbo and had the wastegate tied shut. This was on my stock motored GN with a TE-44 (60 trim, stage 3 .82a/r). No problems with the M5 at all, didnt even take the paint off the compressor blades. Overall i gained a solid 30whp just by placing the one nozzle there, dropped 3/10ths and picked up 4mph

I currently have my M5 post intercooler (just for IAT reduction) but this week i'm going to move it pre turbo to see what kind of differences i'll see.

Everyone always advises against it saying it can ruin your turbo and puddle in the IC but i think it's fine as long as its not a crazy amount.

I think I'm gona try it on my Turbo/Super setup. Gona ditch the FMIC in between the turbo and blower and then spray a M3 pre-turbo and a M15 between the turbo and blower. The blower still has a A/L intercooler under it.

i bet if you take the i/c out you will see a gain with more meth pre turbo it works wonders...

What does M3, M5 and M15 refer to?

Please keep us posted with results of pre-turbo injection. I might try it with my setup.

Is it better to put a mix of methanol/water or just run straight methanol for cooling in pre-turbo injection?

BootnTBSS and Grr did you just spray 100% meht or a mix? i hear there are addvantages to adding water as its higher specific heat/latent heat will absorb more energy. i guess if you are below 100 degress C however you need a fluid that is going to evap before then. and im guessing thats when meth comes in....hmmmmm

is it really that important to atomise the water/meth?? i know the turbine will do it but im guessing (again lol) that its better if it dosen't have to! lol

dose this have any effects on spool? just thinking that if the turbo is working a bit more efficently it might come on a little sooner??

M3 etc refers to M=100 psi. M3 = 3 GPH @ 100, M10=10 GPH @ 100 and so on.

For IAT reduction I use 100% Meth

chuntington101

That should be a mental setup mate!

simething i was thinking of this morning, could you use fuel instead of water/meth?? just thinking there is already a system installed on the car that will diviler fuel at a good presure, the bloody injection system! lol also you have loads of this stuff on board already.

Could it work? im guessing it should ofer similar benifits to spraying meth pre turbo??

i use E85 now but yes you could use gas too.. fuel gets nice and cold when compressed

it's more effective to do it after the intercooler than pre-turbo.

Starting at a 100 degree ambient temp, it's much easier to drop temps from 150 degrees after the intercooler by 50 degrees than to drop turbo/super discharge temps from 300 to 100.

Not according to the laws of physics. Compression = heat.

Denali08

Good point.

Does it reach 300 at turbo/sc discharge?

Does the methanol have any negative effect on the turbo/IC?
