I've had much success with pre-throttle body water/meth injection on my tuned and heavily modified turbocharged vehicles in the past. I understand that this is a controversial topic when it comes to pre-supercharger water injection, but the community is split as to benefits versus the potential for supercharger damage.

Charge cooling at higher boost levels with the overdriven TVS blowers could become an issue, well, will be an issue as the combos of lower and upper pulleys are explored. Besides a twin-screw conversion, this may be a viable option to help suppress detonation and increase air charge density.

Of course the engine internals could become a factor before this matters, but it's worth discussing IMO.

Thoughts?

 

On a $20k track "fun" car, I'd be tempted to try. On a $110k car with an engine that costs more than a weekend "track car", you go first!

 

Lol, that's a fair reply.

 

There are many older 4.0L and 4.2L V8 Jags running water/meth injection. I haven't heard of any that have gone "bang" because of it. Other reasons perhaps but no hydrolocking due to the water/meth.

 

Yes, with a good check valve backing up your solenoid (I only ran a check valve) and a flow sensor or other fail-safe measure, modern systems are very "safe". It is always possible to flow way too much fluid with the wrong nozzle, but that mainly results in quench, not lock. Good nozzle sizing and atomization is always the key along with tight control.

 

Curious if there is any other info out there on this....Pictures ...how too...setup ...cost...etc...thinking about doing something on XFSC.
What would be expected HP increase...I am sure some variables?

 

Got something in the works - prob have the full rundown, dyno, etc. by end of next week

 

So, how many drums of methanol do you need to strap to your F-Type for a 2 hour romp through the twisties? I remember MeOh/H2O injecting one of my cars about 40 years ago and went through a gallon in 15 minutes. Not very useful for serious track time, but the technology has likely changed.

 

This is about a 1/4 mile at a time, which is a serious and respectable sport for many. I'm a road-racer type too, but I respect the pursuit of the best 1/4 mile time, which also requires some serious skills. There's quite a lot of science involved as well.

 

I certainly respect it as well, and recognize that the technology (and required driver skills) is far beyond anything I would pretend to understand.

 

Hey Philly, could you PM me about your blower porting? I want to get it done as well. Also, are you injecting water/meth at the Y pipe just pre-throttle body?

 

The new tech is great and it lasts quite a bit longer than you all may think. I mean if I MUST (you know for research) - I'll schedule a day at the road course and report back to you guys Granted my road course skills are FAR behind you guys.

cbroth - you got it.

 

Bringing this back, any updated and or pictures and also which system (brand) was used?
Thanks

 

I went with an AEM unit. Sadly, I dynoed with a few other mods AND the methanol spraying. I'll try to get a run in with and without the meth.

 

Hey philly,

Ok thanks, sounds good. What did you get with meth and your other mods?
Where did you spray? I'm assuming the y-pipe right before the throttle body?
Also where did you tap in for boost reference?

 

Oh man...I picked up a pretty good bit and (of course) great IAT's. I really need to do a with and without meth dyno. But...the car picked up 55rwhp on a Mustang dyno and car went 11.02 vs. 11.44. The low end toque is bananas. But as posted, the car also had a ported blower and such.

Correct, sprayed at the y-pipe. I'm not sure where the guys tapped for boost reference, I could make some guesses - but would rather not guess. I'll check.

Give David a call at PowerHaus here in Cherry Hill, NJ (856 432-6017) - tell him you were talking to me. They can really give you killer details and some good ideas to go fast

Philly, thanks my dude, appreciate the response...
Also you mind posting a pic of the setup?

 

no luck with the boost reference location?

 

Doubt you will get an answer here. Last post is from ~6+ years ago, and I do not think the member is on here any longer. He moved on...

I tapped into the hosing behind the supercharger that runs to the symposer assembly for my line to the boost gauge.
