Engine/Transmission (1994 - 1998) How much ~BOOST~ is safe?

[JFisher]

I am in the process of installing the water meth injection on my 97 dodge, ctd 5 speed. I will be using the www.Aquastealth.com

kit with the 300cc injector.



I currently am getting around 44 lbs of boost and the truck runs great! I have been told that adding the water/meth injection can increase your boost up to 10 more pounds!



I am worried that if I do this, I might be having to do a head gasket, or something even more serious! I hate breaking down! #@$%!





Any suggestions?

what turbo do you have?

I have the stock hx35 turbo. stock intercooler too.

If you are compressing 44 lbs of boost now that is already too much if you haven't done anything to your head gasket. I recommend o-ringing!

X2 your drive pressure is way up which will kill headgaskets fast!

hey there,

I looked at your truck profile. What is your current timing set at? I would bump that to 15. 5 or 18* before the water / meth thing. Also, I'd look at upgrading the air flow, eg. turbo before water. But, if you think you're going to push 45+ lbs, becareful...

water/meth adds timing, too much and you will get detonation... .

You're already overboosting your turbo and way out of its efficiency map . . . time to upgrade it before doing anything else.

I had a stock turbo making almost 50 psi and added water methanol. The headgasket lasted a week. Do the headgasket and turbo before putting in the methanol.

I disconnected the wastegate again and it seems to run way better!

More power cooler temps!



I am worried that if I advance my timing that will increase the cylinder pressure and blow the head gasket quicker than stock timing. ???



I do run the truck hard but not for long times. No hard heavy pulling for long periods of time.



When I add the water/meth, will it raise my boost? or just run cooler? Does it make a difference if you use only water or 50/50 mix or the boost juice?



Thanks For the info, just trying to save some time for my poor Headgasket.
