TBSS intake and Water/Meth Injection Hey everyone tried searching and couldn't really find an answer to this. I want to run a turbo LS setup without an intercooler and use a water/meth kit to cool intake temperature and other benefits. I have been told to use a direct port setup on the plastic tbss, ls1, truck, etc stye intakes because if you spray say before the throttle body or at the turbo the intake doesn't do a good job distributing the mist/spray into all cylinders evenly.
Is there any truth to that? Would a single plane carb style intake work better at distribution?
Thanks all for the help. I am running this setup on an airboat in Florida where the ambient temps are easily over 100 degrees and have seen multiple guys have trouble with intake temps on forced induction with a2a intercoolers.

Wanted to add the setup. Built aluminum 5.3 with a 78/75 turbo. Plan on running 15-20 lbs. Spinning to ~6,300-6,500 (limited by prop speed and gearbox reduction). I could run e85 if necessary too.
Thanks for the help!

Why no intercooler? Even a **** intercooler is way better than nothing. What is your base fuel going to be, pump gas? Could be done on E85 for sure but you're leaving a lot on the table with no IC. Did I mention running an IC is a solid bet for what you're wanting to do? Intercooler, intercooler, intercooler....LOL

I've seen a couple guys have trouble with intake temps on their boats running forced induction. I'll be running e85, and was going to run the water meth in place of an intercooler. Just looking to understand if the single plane or maybe even pro flow would work better for distribution or are the plastic ones fine. I have a friend that switched to it and his intake temps dropped. Over 200 with a2a down to like 120-150 when spraying water/meth. He doesn't own an LS and has a different style intake.

If you're running E85 and don't care that you will be giving up prolly 50 HP due to very high IAT temps then nothing at all is required. Drag guys have proven E85 will take 250+ IAT temps and not hurt the motor, but go a hell of a lot faster and have a much larger tuning window when an IC is added. I would not run a pre TB meth kit on a factory plastic intake. It's been shown they are not designed to flow liquids and have bad distribution. I haven't really researched an aftermarket intake but they are likely better. I would personally put a budget but decent A2A IC on it and call it good.

That's why I was looking at the carb style intake. Right after the 90 degree elbow put something like this. I figured since the single plane intakes are designed to flow air & fuel originally with a carb it would do well with distribution. Or do the proflow, Holley high ram, etc. Or do a direct port setup. I want to run ~20 psi and try to make it as efficient (and safe) as I can. If I break down in the swamp it's hard to get back home, no trailer to come get me.
I got the new summit log style manifold. I'm putting it on the block tonight to get a look. Maybe I'll try an intercooler first.

Have you considered a water cooled heat exchanger? In a boat, you have an infinite source of ambient temp or below water to help cool your intake charge. E does cool the intake charge also. There's just no way to measure it if it's introduced to the intake stream as it's going into the cylinder head. Agree with the other guys. You might not get totally cool intake air with any kind of heat exchanger, but it will be surely cooler than running without one. You'd think, with a large prop moving a huge amount of air, you'd be able to position a h/e that would have enough air flow to be of benefit.

Your proposed water meth idea and injector deal would likely work fine on a cab intake. It is a solution, it just isn't the best solution, especially in a boat where you should have tons of room. If you can't provide a reason why you can't just add a decent A2A or A2W intercooler, both of those are much better options.
This is $395 and would be very legit on your set up. It won't ever stop spraying, have a pump die, have distribution issues, need to be refilled with liquid you need to purchase etc. etc.
