NX intercooler sprayer on MSP

[mspeed101]

Hey I was wondering if its safe to run this on a msp with all the bolt ons?

[KzA]

its safe to run on anything...

Itll only cool down the intake charge a bit, its not like its putting nitrous into the airstream...

It might lean you out a lil bit, but I cant imagine it being enough to give you trouble..

i know there some people running this..but you cant boost to high or you will hit fuel cut do to the very low intake temps..

I have heard of this lowering intake temps by 30%. The intake temp difference between CO2 and NO2 sprayers should not change by much. CO2 is cheaper...make friends with a welder or a paintball store that have fillers. System would be setup the same I believe (in regards to solenoids, tank, etc). Let me know if you get the system, I am interested.

Should be fine to run on the MSP..b/c the msp loves to run uber rich!

Its cool at stock boost but I hit fuel cut alot sooner when pushing 9psi. at stock boost and just the sprayer I was holding 7.5-8.0psi all the way to redline.

I belive they have a fix for this called joep fcd.

I have the NX-Ntercooler sparyer. And it DOES NOT.. I repete it DOES NOT have any effect on when you hit fuel cut. however a CAI does. Run the tsock air box and you wont hit it. The air is already metered before it goes through the IC. Your intake temps are colder but the MAF doesnt know that.

Im blowing through my MAF

Yes it would. Colder air is denser. It doesn't matter when it gets cold it still allows more air through the maf thus increasing chances of fuel cut.

It is getting cold after the MAF. The engine might run differently with a larger amount of mass than was metered, but you should not hit fuel cut. Remember, the MAF is oblivious to the sprayer when it is not on the pressure side (the MAF that is).

Actually blk zoom is probly right about this..

i have never hit fuel cut...but than again i am no msp.

The fact that it drops the air to -30degrees..means that the velocity of the air flying through the maf will def increase..so yeah..the chances of hitting feul cut is greater..I know..that w/ my setup..when i hit the nos..the car def pulls harder..and also..i noticed that since the temp of the air drops...my car seems to lean out a bit...

The fact that it leans out the mixture..is beneficial for a msp that runs Pig Fucken Rich...But for me..well..that's no good..which is why i am creating a seperate map for the nos..

ah its not that much of a difference

[acidbbg]

oh really..when i hit the nitrous..i do notice that boost will go above what i set it at..aka..i set boost to 10psi...and hit the nos..and i saw 12psi...but it dropped back to 10..by end of the run.

Okay... So where does the extra air come from then?? Colder air is denser correct? Denser air means there is more air molecules in the same space right? So when the air gets colder it condenses and more air rushes in to fill the space. All that air still goes through the maf. Thus you are more prone to hit fuel cut. It doesn't matter where in the system it gets colder because it is a closed system with only one inlet. I have proved this every time I used my co2 sprayer before I put the fcd on 2yrs ago.

Ah....you got me. You are totally correct. I didn't sit down to think about it last post. Just to spit more mechanical engineering out there....air does rush in, due to the moving car....but it mostly gets sucked in. The level of entropy within your intake pipe is a great deal higher than ATM, so airflow into the intake is less natural. The veolicty of the car drives the air in to a degree, but your engine grasping for more is what really gets it in there. And like you said....it is a closed system; The more the engine needs air, the more it pulls through. The more area within the intake system, the more it gets filled.

Nice thread. These things are all good to understand, especially while toying with your car. Knowing what is going on under the hood....and why it is going on, helps determine problems faster....come up with solutions faster...and allows one to mod better.

Spend the money for a FMIC, it will turn out to be cheaper and better.

[BlkZoomZoom]

prove it.

[A.V.MSP]

wouldnt the combination of both be better? have the sprayer for a little extra when needed

[BlkZoomZoom]

Not in my opinion... then again this year I won't be running a "intercooler". And I only run the stock one now.

[A.V.MSP]

How come you are not gonna run one? or do you have another trick up your sleeve?lol Why dont you think its better, cuz of pressure drop or are FMIC's over rated?

[BlkZoomZoom]

If what I'm working on does what I expect, or even half, I may be looking for ways to warm up the air after it so that it isn't too cold. All with virtually no pressure drop when compared to a regular intercooler.

I personally don't see the benifit of a huge intercooler for drag racing. And I personally have never experienced any kind of "heat soak" that everybody talks about.

[A.V.MSP]

very nice man. Never heard of anyone wanting to warm up the air. I tptally agree with you about the huge intercooler for drag racing. The only time I got heat soak was driving the car in 100 degree weather and it would get mean lag, may have been from the pipes stretching when they got hot.
