Ways to lower intake temps

[08nastygt]

Is there anyways to lower intake temps safely. I really don't want to run meth after reading more about it. I have a turboed car and it was 82 out yesterday and my intake pipe was really warm. Would a turbo blanket help?

Would nitrous work.

I would think an intercooler spray bar would work. Something like this http://www.amazon.com/NOS-16034-Intercooler-Spray-Bar/dp/B000COYBCW

they dont do jack shit

yes get a turbo blanket, wrap you pipes and have them coated. what is the iat getting to. jsut because the pipe is warm doesnt mean the iat are high.data log at cruise and at wide open throttle.

to cool IAT you can either remove the heat from your intake air stream via Meth, Meth&water, Water, N20, A2A Inter-cooler, W2A Inter-cooler, larger water reservoir for your W2A, add ice to your reservoir.

Or you can remove heat from your engine bay, i.e. vents in the hood/side panels to lower temp in engine bay, or coat your headers/wrap(or both) to keep the heat from ever getting in your bay.

Thats about it. Nothing else really works. the N2O sprayers on your inter cooler dont have any measurable effect. but look/sound cool!

Yeah for a second and then blow the engine since hes already pushing the limits with the turbo

killer chiller

He has an air to air setup

I didnt coat the pipes i am just doing a turbo blanket and header wrap on the up/down pipes.

Did the hood scoop mod

See my thing is, is I feel like when its like hot out my car is dog slow. Almost like heat soaked so bad it doesn't want to move.

What's your hang-up over water/meth exactly?

 

[08nastygt]

From what I was reading, if someone doesn't know how to tune for it it can be a very bad experience. Then if you don't run it right it seems like some cylinders can get to much and cause your motor to pop. Does that seem right or am I being to conservative? If someone like you told me to run it and how to run I wouldn't second guess it.

You beat me to it. Meth would really help him. My car felt N/A on really hot days and sustained boost. Didnt want to get out of its own way..Meth and another pro tune cured that.

Running your car the way it is now is not helpiing it either. It feels dog slow becuase the IAT's are getting so high, its pulling all sorts of timing to compensate.

Steedman what stage of snow did you go with, also how many nozzles are you running?

stage 2..And Im using the next to largest jet, I think its good up to 500 whp..I havent gone through 2 gallons of boost juice since last June. Run the meth from your windshield washer tank, and you will be fine. To be safe, you can get the low level indicator light..

On a turbo car I was seeing spray like in the intake pipe and also into the turbo? Then I read that it can harm the propellers.

Not sure for a turbo, but I spray mine after the blower, but before the IAT sensor..Im sure you can do the same...

I think your cautious approach is absolutely warranted. But let's look at a couple of your concerns you listed.

Tuning for water/meth is very straightforward. I think if you worked with a knowledgeable tuner you would have no issue properly dialing it in. The only serious tuning complication I could imagine would be if the flow of water/meth to the engine unexpectedly stopped during a WOT run. This can be a serious problem, but there are a few tools available to stop accidents before anything goes wrong. More on this in a second...

As far as running too much, I've never heard of that problem before but that doesn't mean it isn't possible. Methanol is corrosive to aluminum, but if you're spraying a modestly sized 50/50 mixture I don't think this is a serious issue. Run the proper sized nozzle and you should be okay.

As I mentioned before, the only real concern in running water/meth is making sure the flow doesn't stop, be it from a break in the line, a clogged nozzle, failed pump...whatever. So long as you can ensure good flow, you should have a relatively uneventful experience running water/meth. It's evaporative cooling effect really brings down boosted air temps, and the added octane does allow you to run more timing in some circumstances. All good things.

Here's what I recommend. Labonte Motorsports makes this device that monitors water/meth flow. In the event that water/meth flow stops (despite the presence of a signal to the pump) the unit will output a 12-volt signal which you may use to trigger some event: Shut off your wastegate solenoid (bringing you down to wastegate spring), change maps, pull timing, whatever. The point is that you'd be protected against like 99% of the potential failure modes from running water/meth. The only way this fail-safe would, well fail, is if you had a break in the line AFTER the fail-safe module and still had water/meth flowing through the line. In that one particular circumstance the you would risk serious engine damage.

Great example.

Where would be the best place for me to spray my car at you think?

I'm not sure if you were asking me but I'm going to tell you my opinion anyway, lol

On a turbocharged car I would spray several inches before the throttle, and preferrably not right behind a bend. I would be hesitant to spray before the turbo only because the methanol may do funny things to the impeller. I've never done it though so I don't have any useful experience to share either.

When you spray you're really looking for two things: Maximum evaporative cooling and atomization, and equal distribution to the cylinders. Typically people spray just before the throttle as a compromise in cooling and equal distribution, but you can get creative and find better spots if you're sneaky.
