Beating the heat with TVS?
Run a DBL nozzle setup into the top front center of your intake manifold; 1st and 2nd gear should cool you enough to stabilize and hold an acceptable (130-160) IAT2 temperature throughout 3rd in that kind of weather.
i went to school to pick up my little girls and it was hot outside so i left the car running with the ac on for about 45 minutes and my iat2 s got to 140 s never got higher than 140 s. is that normal? and that is with the 2.9 pulley and cxracing heatexchanger and no other cooling mods.
If you want your IAT's to come down quickly at the track, start by lowering your coolant temps. Turn the heater on in between runs and pop the hood. That helps out a lot. A bag of ice on the blower between runs helps out too. Finally your supercharger should not get hot if you are properly spraying meth down the track. After intial cool down, shutting the car off and pushing it in the staging lanes doesn't hurt either.
imo...grab a WOT box...sitting on the 2-step will draw in more air this lower you IATs...strictly a track benefit...but why not...cheap and also helps more than just ur IATs...better 60'...
Hey, see my suggestion in your other thread first before you throw in the towel. Hell if you get that M5 jet in and send me your tune I'll make some changes to it for the better for free. If you can datalog some runs too even better.
it is def more beneficial to spray after the laminovas as far as removing heat, however, that doesnt give a lot of time for the meth to atomize with the air before reaching the cylinders.
I disagree. Killing the heat from the damn thermonuclear reactor is more benefitial so the luminovas are starting with a lot cooler air to begin with.
physics FTW!
The reason I feel this way is because the intake manifold with those luminovas is sandwiched between a thermonuclear reactor and a combustion chamber. It is made of aluminum which heats up really easily and you can bet being between those two heat generators it gets hot. Neutralize one of the those heat generators, add the coolant feature of the luminovas, and now by the time we get to the combustion chamber we are chilling. Remember, the M62 doesn't compress interally, it just crams air into the intake manifold so if that air getting crammed is cooler we're better off. Now if you were to spray before and after, we could get a double wammy out of it.
well, theres a good amount i can continue with, but i'd rather not cause im lazy right now (maybe tomorrow? lol). It's definitely more beneficial to spray after the laminovas though. If you spray it before the blower to cool your "nuclear reactor" down (lol), then you're wasting potential cooling power on cooling off the blower when instead you can focus all of the cooling power of the water/meth directly at the compressed air.
also, lets say the meth/water mix can remove 20* worth of heat. The laminova system will remove heat proportional to the temperature differential between the coolant flowing through them and the IAT2 charge. Therefore, the hotter the IAT2, the more heat the laminovas will remove.
now, im gonna use some made up numbers for this example. say the lamonovas remove 50% of the difference in heat of the IAT2 charge. lets say the coolant in the lamonovas is 60*. lets say right after compression (with no meth), the charge temp is 120*.
example 1: spraying before the blower/laminovas
the 120* charge is dropped to 90* by the meth. this 90* charge then passes through the laminovas, which will remove half of the temperature differential, as stated earlier. The temp. differential is 30* (60* laminovas and 90* charge). that would mean once the charge passes through the laminovas, the final IAT2 charge is 75*
example 2: spraying after the laminovas
same numbers. the 120* air charge passes through the laminovas. The temp. differential is now 60*, meaning the laminovas will remove 30* of heat. This leaves you with a 90* air charge. Now spray the meth after the laminovas have done their work, and remove the 30* that the meth can, and whala, you have a final IAT2 temp of 60*, 15* lower than the first example.
The only issue with this is, as stated, there isnt a lot of room between the laminovas and the cylinder ports for the meth to distribute and atomize with the air charge.
it all comes down to the fact that the laminovas cooling capability depends upon the temperature differential, whereas the water/meth mix does not.
i guess i wasnt as lazy as i thought...lol
