N-tercooler makes 48whp&56 lb/ft TQ on bolt on EVO8

[jdmawd]

Local dsm shop owner had his bolt-on evo8 dynoed up a Altered atmosphere in gathersburg today here are the results

Not shabby, have you noticed a noticible difference with your kit?

 

[dsm]

man if it really makes that kinda power id be intereted to try it on my car

 

[al5dsm]

^^^^ i agree, if it really does make that much power, itd be a good investment.

Cant honestly say, ive been very lazy the last couple weeks. I have not done Dick. On a good note my favorite local dsm shop just got an AWD dyno. So I should be able to give you so feed back soon. Im very excited about having an AWD dyno in walking distance from my house 48 whp on a bolt on EVO 8 is definetly something to look at

If my memory serves me he still has a stock intercooler. If that is the case then it definitely makes sense. Get a turbo blowing nice hot air and cool it was down with the sprayer. I would also theorize if he had a 216 core on there he wouldn’t have seen the same improvements because the IC core wouldn’t have been all that hot.

I still think that he would see a MUCH bigger gain spraying all that nitrous into the throttle body as opposed to splashing it over the IC.

those are impressive numbers none the less. jdm do you plan to dyno with nitrous and without to have a similar compartrative on your car?

Absolutely but ill be spraying co2 just like dan did. i can get co2 all day for fee

 

[DSMTurbos]

dan sprayed nitrous on that run actually http://www.machvforums.com/showthread.php?s=&threadid=22608&pagenumber=2

i just would like to see a non shop dyno it (not saying that dan is baised)

 

[GaRn]

co2 generally better for intercooelrs than nitrous?

 

[Flat Lined]

From what I hear it is that is a bit cooler and cheaper. My cousin always got the "whoa you running nitrous?(acutally they said NOS, but I perfer to be correct)" when people saw the bottle in the car.

 

[Groomz]

I don't think spraying nitrous into the engine bay is too smart. CO2 is a pinch safer. Buts that just a thought....

 

[GaRn]

but nitrous isnt combustable until its under alot of pressure, or thats what i thought.. which one gets colder?

 

[jdmawd]

i personally would not run N20 for two reasons. 1 its cost more to fill and 2 my filter sits right next to the intercooler. would not want any N20 to get sucked into the air filter.

i would ..

I have an ntercooler on my car, but I also have a slightly shorter version of a 216 (28 x 8 x 3.5) and when I used my ntercooler at the track I didn't notice any difference in my 1/4 times.

I think it's partly because my intercooler is so large it never really gets hot anyways. I have noticed that when I come back from a run I touch my intercooler the hot side is a little bit worm the cold side is freezing and thats without the ntercooler so I can't really see how much benefit I get from adding extra cooling. If my intercooler were small or a starion unit or seomthing like that then yeah I could se 50hp gains but I think I have that 50hp gain already in my big intercooler setup.

 

[GaRn]

good point.. would it be better for my 20g to run with a sprayer and modded SMIC or just go FMIC?

That really didn't make much sense. That's like saying your car would be just as fast in 110* heat as it would be in 60* heat. because of the size of you're intercooler.

I have an intake temp gauge in my car ill have to see what the charged air temps look like while spraying the core, the rest is tuning.

 

[kpt4321]

N2O is stable until the molecule is split up into its N and O components, which doesn't happen until it gets really hot.

I've said it before, and I will say it again. If you're on the street moving at decent speeds (good airflow through the FMIC) then spraying it with N2O or CO2 is not going to do you much good. In reality, it only really make a difference when the temperature of the IC core is rising.

It will always help A LITTLE but not enough to be worth the cost in most instances.

IMHO.

I agree Kyle. I only ever see test results from dyno's never track testing. I'm interested to see what jdmawd's results are without the dyno. Keep us updated.

 

[greyforestgst]

well of course a ic chiller is going to rock ####ing hardcore on a dyno, there's no air moving through it

ive been thinking about making my own co2 kit using paintball hardware, and making my own cooler bracket...

Well make sense or not, the fact of the matter is my car goes fast enough and makes enough power to be able to see if there was a difference or not and in my case there was no difference. Believe me I was surprised to.

I tried it in 100deg and 75deg weather at the track and did back to back passes with it on and off and different combinations of spraying for part of the track and the whole track and every thing else I could think of and honestly it didn't matter what I did, the damn thing didn't make any difference in my 1/4 time or MPH anywhere on my time slip.

It doesn't make sense to me either I would think it would help but what I figure is my intercooler at the end never gets hot even in 100deg weather the cooler end tanks on the cold side are still cold even without the ntercooler so Its just not making enough of a difference on my car to show on my timeslip. If I had a really small intercooler which heatsoaked then maybe it would help. I dunno...

My inlet and outlet are centered on my cooler so you can see how much goes upinside my bumper. The cooler is also spaced back 2 inches from the bumper so air does get up in there no problem, I shaved the re-bar back on an angle to help air up there and cut my bumper cover back to match for airflow.

I would agree with you Jim. A 216 sized core will probably make sure the intake temps never get above ambient. Combine that with a larger turbo that isn’t WAY out of its efficiency range and I doubt you would see a big gain when the temps go up 20 degrees or so. Hell I ran a 126 trap on pump gas on one of the hottest days of the year. That doesn’t mean I could go back now and run a 130 on pump gas. At least I don’t think it does hehe. However in the case of an Evo where you have a decent size IC core and a turbo running out of its efficiency range its not a big shock that it picked up all sorts of power being brought down to temps at or below ambient.

Man, I am really pissed for not pursuing this idea back in ’96-’97, when I first got into racing DSMs and was still heavily into paint-ball . We discussed this on the old Talon Digest.

My main objective to using CO2 sprayer was the fact that CO2 is a fire suppressant, so if you ingest any of it into your engine, you will LOSE power. Stock DSM sidemount is just under the air intake, so I thought that it was not going to make for a good combination. Look at it now, everyone sells these kits on e-bay .

I wonder how much of Dan’s gain was due to N20 making it into the engine? I would love to see him do a 3rd run, only this time using C02.
