just kidding...

it's like this...the air coming from the ProCharger head unit is at its hottest point...this creates heat soak under boosted runs...I'm attempting to cool the air before it hits the IC using a boost referenced switch...it will not come on during normal driving...it WILL under boost, the charged air will then be cooled somewhat before hitting the IC, then pass through it to the MAF, then get hit with a spray of 50/50 (maybe straight meth one day) before TB...

Having said this...it brings up the question I posted a couple of weeks ago...why not eliminate the IC altogether w/ and spray meth before TB...as suggested by an undisclosed person... ...I don't get on it hard that much around town, so, would it work? who knows...I think if I did that, I would have hot air coming at my TB because there would be nothing cooling it UNLESS I was at a boosted level to kick in the meth...

and we all know with a ProCharger...I am sucking in hot air and then charging it...so, I am trying to come up with alternatives...to use what I have + a lil' sumpin'-sumpin'...

 

You will never convince me an intercooler isnt needed unless its a track only setup. I still say, the nitrous would be most benificial spraying on the discharge side of the intercooler. The way I see it, the intercooler cools the air, then the nitrous cools it even more. Spraying on the inlet side would work, but I dont see how it can help cool the air charge down as much as spraying on the discharge side.

 

We agree on this...

 

I usually see 10 deg above ambient temp after my charge air cooler, so if I sprayed nitrous before the cooler it may cool the air down below ambient but the charge air cooler would then become a charge air heater. It makes more sense to me to spray after the cooler.

 

i am not informed on spraying and using a supercharger. but i would think if the intercooler is going to cool the air then spraying after that would cool it more. if the spray is cooler than the intercooler and you spray before the i/c then the i/c might heat the air back up. anyway to move the maff to after the i/c? not sure if you said it was before it or after.

 

Haha. I see. I was a bit *** backwards. You arent trying to cool the nitrous, you are trying to cool the aircharge. Ill go sit in my corner now and shut up.

 

my current set-up...inlet to TB changing soon...lowering the MAF closer to the IC, coming out of it with a 4" tube reduced on MAF end...one piece tube...no reducers...only 2 couplers...

well the way i am thinking of this is you want to spray it on the n let side to help it ic cool the air ,but say it is 90* outside and you spray it in front of the ic it will probably drop the ait 20* then it goes through the ic and gets heated back up because of the hot air running through th ic so it will not be to u'r adv. to do this. a if i am wrong then please tell me.

 

If you sprayed before the I/C it would help to prevent a heat soaked intercooler, heck spray it with a dry shot on the intake side of the supercharger.

Without knowing the calculations for the thermodynamics of heat etering and leaving the system by compressing a gas, the I/C, the injection of nitrous, the ambient air temp, the only way to determine which setup will give you the coolest intake charge would be to install thermal measuring instruments at : 1. the blower intake, 2. the blower outlet 3. the I/C inlet 4 the I/C outlet, 5. and the t-body inlet and doing some experimenting by moving the nitrous injection point all around. Whichever gives you the coolest final t-body inlet temp, is the setup you will want to use.
