They're cold pulgs but work well for me.
btw which is your evo, dr.evo?
an additnional 50hp might only be worth 1-2 tenths on a 650+hp car. The faster a car gets the more power it takes to make the same gain in ET and MPH. And on street tires another 50hp and even more torque might not be usable in first gear on the launch.

Logic dictates that the nos sprayed isnt even travelling upwards when on a dyno with fans and even more so moving on the street.
How can it get into the intake if the air current is pushing it towards the back of the car? I just don't buy that enough of the nos being sprayed on the intercooler can make 25HP.
As for the afr's changing, we saw this (reefro and I) on a buddies with the sprayer and we had a discussion and concluded that it was probably due to the intake charge being much cooler and therefore contains a higher density of 02. Maybe this is what makes the extra power, but I just can't buy the theory that enough nos is going into the intake to make 25HP.

Whats the "old rule" for ever 10 degrees you get 1 hp . and you think that the car gained 25 hp from cooler air . WOW

actually isnt it for every 10 degrees you gain 1% hp?? not just 1 hp...
so in this case to get from 261 to 286 you would need to reduce the temp by about 90F ...
anyone have any idea how cold these n20 sprayers can cool the air going through the intercooler by?? i have no idea

Arguing over these stupid IC sprayers just baffles me. Who cares what it does on the dyno. Has anyone made any ET/mph gains on the track with one of these?
I firmly belive these IC sprayers are a waste of time and most of the power gain SOME people see is the n2o getting to the air filter and that additional o2% going through the air filter.
Why would you bother to buy and install what is basicly a complete nitrous kit and not spray it into the engine and make the most power you can with the parts you bought.
Spraying the IC seem to me like buying a turbokit, installing it and using the hot air it puts out to heat the windshield. complete waste of your money and parts.

the amount of nitrous you need to make 50hp is sprayed through a .018" jet. The jets on an intercooler sprayer are HUGE...they dump the equivelent of a 100+hp shot worth of nitrous in front of the car. how you can think that won't make it through the radiator and into the air filter I can't understand.
