Dan, did you monitor your boost levels during the run? I'm just curious to see your max given the massively cold charge.

Thanks!

 

Have you driven it on the road or at the track and used th N-tercooler. If so how much betterdoes it feel now?

 

Sorry, no. (The Dynojet doesn't log boost.)

Damn you Mach V. Now here's another thing I have to buy. It's getting harder and harder to hide my addiction from my g/f

 

That wouldn't even make it one lap at most any road course! Wow that would become some expensive seat time. $50 a lap.

Though for the ice down your intake and waste 20 mins prepping a car for a 15 second shifty shifty experience, that has some good gains.

Do they have a slower release version or something that may last at least 30 mins?

 

Of course this will work good on a dyno.

#1 The intercooler itself isnt working. There is no air flowing, so you aren't seeing any heat transfer due to it. Under normal circumstances the delta T will be lower and therefore any additional cooling device like the Ntercooler will be less effective.


#2 The air from the Ntercooler is able to "sit" on the intercooler longer, since it is not being pulled out at 80+ mph. In normal driving, the cold air will be dispersed much faster and well before it can be effective.


Im not saying it does nothing under a 1/4 mile drag, but it definitely won't be as effective as it is during a dyno pull.

 

All our pulls are done with a 3-foot diameter high-speed fan blowing directly on the front of the car. Now, I haven't done a wind-speed test on that fan, so I admit I don't know what speed the air is going through the intercooler...

I actually think it would work BETTER at speed, since ALL the liquid will be pulled THROUGH the intercooler, and none can spill off the front. (This happens a little on the dyno.)

That is an excellet point, any N20 making into the engine will boost power. Any C02 making into the engine will reduce it…

So unless you have a system where intake and I/C well separated, your choice for cooling gas will be very important and might be worth the extra cost.

But if it is N20 in the engine that is accounting for some of that power increase, I would much rather spray right into the engine. It will be much more controlable and would not waste as much gas.

I would love to see 3, back to back runs:

-stock
-N2O cooler
-CO2 cooler

I can also see different cars responding differently to such test, depending on location of their air intake with respect to their I/C.

I dont see how gas sprayed at the intercoller would stay concentrated enough en route to the intake, a 90 degree turn and a few feet straight up, to make any signifigant impact on hp

 

uhhhh......no. explain to me exactly what force would cause the nitrous to go up towards the intake when a fan is blowing the gas parallel with the ground.

 

Yeah, Leon doesn't know what he's talking about.

 

I had the same thought as Leon; if I had the time and the gas (), I would refill the bottle with CO2 and repeat the test. I think Alfriedesq has done this, maybe?

Take 5 there sport, Leon was making a very valid point. That was not specific to the stock filter location of the EVO.

Last I checked this was not a EVO specific system and his point was. If you have a setup like He and I both have. Where the intake filter sits next to the Intercooler.

You run the possibility of having C02 or N20 sucked into the intake. Its not helpful to attack accurate comments from very knowledgeable members.

 

My filter is up near the I/C spray reservoir bottle.
