hello i'm from greece and i want to put a wi to my car but none here have any idea.I also have a strange car.Well lets start. My car is a renault 5 alpine turbo.The strange with this car is that it mounts the carb before the turbo so the turbo dont just boost air but it boosts all the air/fuel mix. after the turbo there is just a pipe which goes straight to the inlet.There is no intercooler because of this setup(a/f in turbo). So only the wi will help me. I boost up to 1 bar(14,5 psi) but i retard to much. Please help me with the questions i have.
1: where sould i put the jet before or after the turbo?
2: what jet should i use and how should i calgulate it(i dont have injectors to calgulate the fuel that my car uses in order to make a 15% wi, i use carb)
3:in what psi should the wi work?
Finally do you think wi is agood idea for my car? Thank you very much you are the only one that can help me....

One idea would be to inject after the carb and before the turbo.
This way the carb's fuelling balance wouldn't be affected and you'd have maximum cooling effect afterwards.
Can you post pictures of this part of the engine? If there is a pipe bend it might actually be useful for the water atomisation and distribution before the turbo's compressor.
Next best thing would be injecting after the turbo I'd think.
