intake temps

[redgsturbo]

Hey, I installed a charge air temp gauge mounted in the elbow before the tb and here in charleston (95 degrees) I have found that the stock intercooler is keeping the temp under 105 degrees while driving at 19psi on a T-25 (yes yes, I AM trying to destroy the turbo) Thought this might be of interest. So at what point is the air getting heated enough to warrant a $1000 worth of intercooler?

Well, thanks for the info. Honestly I find that hard to believe, but I am not going to say your doing something wrong. If you touch your upper intercooler piping does it feel hotter than the ambient temp? How about the lower intercooler piping. Just some ideas so that you can verify your temp sensor is working.

P.S. It isn't measuring Celcius is it? That would be about 220 F and sounds much more reasonable.

keep in mind this is on a T-25.. it is not celsius, its a westach unit. when I stop the temps soar so I know its working right, as soon as the engine starts sucking in alot of hot engine bay air it shoots to about 150 or more like while sitting at a stop light. In the winter time the temps never even go above 90 unless I REALLY push it(which is the lowest reading on my gauge) just flooring it through 5th to max speed it gets to about 120

dont know how reliable this is but this is a quote from autospeed's web site
In all cars, the lower the intake air temp, the better. In a naturally aspirated car with efficient cold air induction, when the car is moving the intake air temp should be less than 10 degrees C above the temp of the day. The best we've ever seen is 5 degrees above ambient, and many cars - even after cold air intake modification - still have an intake air temp about 15 degrees C higher than the day temp. In forced aspirated cars, the highest temp that you want to see - depending on how much boost you're running, of course - is about 30 degrees C above the day temp.

maybe I could mount a second sensor before the intercooler

what did the gauge and probe run you? autometer has a 2 channel gauge on carparts.com for $350.(way to much for experimenting IMO). on a side note, I recently bought a portable 12v fan that takes icepack inserts. I was planning on hooking it up in front of the IC to blow cold air on it. I wanted to take some temp reading before and after the install to see how much of a difference it makes.

[redgsturbo]

it was something like 70.. but I had to wait forever for them to make it.. as for the fan.. I would sooner go to the local grocery store and break off some of those veggy rack water sprayers to make a nice intercooler sprayer :)

Thats the best description I've heard for those sprayers. Does anyone know were I can get some of these. Nobody knows were to get these around here.

Thanks,

I used to keep various exotic reptiles... some of them require spraying devices as chamelions lick water of the leaves (which you must mist on). Check aquarium stores. Or... some grocery stores are open 24 hrs...

I just bought 15 ft of vacuum tube,a tee valve,an agaurium one way valve and a Ford Explorer windshield sprayer nozzle for under $12. I cut into the rear window sprayer line where I put the tee and the one way valve (to pull in air to break the siphon) and ran the vacuum line out and under the car and then Dremeled a hole for the windshield nozzle to fit right in front of the IC (side mount) through the splash shield.

Now when I'm dragging,after each shift I just push the botton on the dash and spray away. I pour a mixture of 70% rubbing alcohol ($.50 a bottle) and 30% water in my rear washer tank. Use alcohol because it stays cooler and evaporates fast (no moisture on the track),especially on a hot IC,the water is there to dilute the alcohol so it isn't flammable.

I don't know how much it helps but for a $12 investment it can't hurt.

first off if you were running pure rubing alchol and water at a 70/30 mix thats still flamable. don't belive me just go into your local albertsons and buy some rubbing alchol there its almos allwase 70/30 righ out of the bottle unless you get the expensive shit wich is about 95/5. just put some it a spray bottle and get one of those super long fireplace matches and poof. second there is no way in hell your stock ic can be working that good. i have an ic sprayer and even after spraying my ic for a while it is still way to hot to touch. have you ever felt that throttle body elbo i did onec and burnt the piss out of my hand. now if your stock i/c was that efficant then imigan a frontmount with a good watter sprayer, can you say more than 100% eficant.

my temps are verified on more than one guage with more than one temp probe at the elbow.. .those are my intake temps.. accept that.. its not an arguable point i am running a t25, which that intercooler is designed for.. i dont have the time or inclination to go putting a probe before the intercooler so i will probably never know how much that intercooler is cooling the charge i clean the inside and outside of this intercooler fairly frequently.. (lots of oil had accumulated from when the valvle cover vent had spit)
