Water injection for a 355?

Water injection as far as i know is only used in short term, high boost applications ( like 1/4 miles runs0. meth is usually the preferred fluid, but it its sprayed in the intake usually well before the motor, in order to fully evaporate in order to cool the pressurized air.

It would have zero benefit in our cars unless you slappin some turbos on.

Look into fuel treatments or seafoam for internal engine cleaning (after some research)

 

It will help with steam cleaning your motor if that's the question.

 

No

 

My personal opinion as a car nut and aviation mechanic is there is no benefit to a fuel additives/cleaners. Gas is already a solvent. only fix for a clogged injector is removal and professional cleaning.

As for carbon build up, warm it up, drive it hard. it will burn it off.

I've used seafoam on a few of my other cars with good success, but the risk outweigh any benefit to me on a ferrari. I would not recommend it.


Stop worrying, just drive.

 

Anyone on here remember (Johnk possibly) the old '63 Oldsmobile F-85 Jetfire with the 215ci aluminum engine that had a turbo with FACTORY water injection? Nothing like some sixties GM engineering for our F cars.

 

IMO there is no real use for WI on our cars ..... but I've working on a new heatshield system that will reduce intake temps enough to see some HP gains ............ before and after intake temp data will be shown along with dyno data .... we'll see how the numbers turn out ...

 

I will be the lone dissenter. I can guarantee you that if your naturally aspirated sport car or racecar was on track at Buttonwillow raceway today that water injection would increase your horsepower. And yes I have done this. WI works even better with compressors. There is a mild cleaning action of the fuel air water mixture to mildly improve the valve cleanliness. But the reason for WI is not to reduce carbon but increase performance. A much easier way to have cleaner valves is just to make valve cleaning part of your routine major service as done here on this Ferrari motor. It takes 10 seconds per valve with the proper equipment and experience and scares the begeezzers out of people who don't really understand. It ain't magic folks, it is just an engine and they all get dirty.

But the way to keep them clean is to use good gas and drive the car all the time.

 

Nice work ..

+1 .......... driving the car often does a lot of good in this respect ...

 

There are expensive systems and inexpensive systems. There are systems that are completely mechanical, but i've only seen it demonstrated on boosted engines. Some systems run off boost levels, some systems run off what your fuel injectors are doing. If you just want to clean the motor, I suggest looking on youtube for some mechanical systems built cheap. Use distilled water.

 

Hydrogen cleans really well and speed up flame travel speed heheheh

 

Quite a few issues in engines occur because they get driven too cautiously too often.

Good quality petrol/gas is a must, regular use is ideal, and the occasional "Italian tune-up" works wonders on engines!

Sometimes you've just got to blow the cobwebs out of them! - It's for their own good!

 

I had always thought the water and methanol injection were to lower the fuel charge temperature for greater density and, consequently, more power. I am not sure what the actual benefit would be but I wouldn't try it unless I was on a track and it meant something. For the street, bah, wasted.

 

Walnut shell blasting, bmw and others sell a tool that's basically a sand blaster hooked to a shop vac for this exact purpose. You could do it yourself if you had a decent wand for your sand blaster and got the right media. Just need to be very careful not to make a mess and be sure the valves are all the way closed on each cylinder when you do it.

 

It won't clean the combustion chamber but will clean the carbon off of the valves and in the intake port. You'd have to do the same on the exhaust ports to clean the exhaust valves. Here's how it's done on the bmw's:
