very high egts.. water meth?

I see way to high of egt temps at wot it is 1700-1800 and 600-800 highway 80mph. looking at water meth kits to try cooling it down what is the best ones? I was also debating between watermeth or steed speed exhaust manifolds until i seen that u have to buy $700 up pipes for it. are there cheaper exhaust manifolds that will help lower my egts? i dont want to melt my pistons? mods are in my sig.

Re: very high egts.. water meth?

From the information I've gathered water/meth is probably more dangerous then you high egts are. Try a ported intake and manifolds should give you a 350 degree drop

if he sprays just water or a -0 rated fluid what is the danger? assuming it is installed as it should be and runs as it should.

Water meth is not the solution to your problem, neither are aftermarket exhaust manifolds. Whose tunes do you have?

Re: very high egts.. water meth?

your cruising egts sound fine for your mods and your WOT egts sound only a little too high. You could always have your tuner pull a little bit of fuel.

Does your RCD turbo still have a cast wheel in it? A billet wheel would help out. Also a ported intake manifold would help out.

Water with NO METH will definitely help out. But IMO I would get the egts where you want them and then make them even better with w/m kits. I would not use a w/m kit to get them to acceptable levels.

Re: very high egts.. water meth?

Dual hpop might help atomize fuel better too. That will make things more manageable. Without ICP these are big smokey turds. The 100 nozzles might be too much for the stock pump to keep up with, depending on the tune.

I would look into the tuning though. Guys are running 285/100s on a stock turbo and not melting pistons.

You could pull the stock intake manifold and see how dirty it is too. If you just clean that it could help you out some.

A billet wheel does help. It pays to also smooth out the path of airflow with a ported intake and such.

After w/m I can run 65-70 all the way up even slowdown to 45 or slower if I get stuck behind a semi then accelerate back to 65.
