As title states.... looking to built a 750whp or so setup - has anyone run big hp thru an AWIC on the street? Heatsoak issues? How well does it work? etc......

 

i'm curious on this. Next years setup consists of a 6x10 pwr barrel and 2 heat exchangers

 

bump!

 

bumpo!

 

I'm interested to see what comes of this as well, but i have one question. How can you drive a 750whp Honda on the street and have any fun with it. For all practical purposes, i would much rather have a 500whp car that spools before 7k rpm

You cant, didn't you know thats the cool thing to do. lol

 

500whp on the street isn't fun either.

 

Its not a Honda

I've already got almost 6k of lag.... I dont really care.

 

i don't see how power levels matter, I would say that an a/w setup has to be designed to meet the cooling requirements of your discharge from your turbo.

you will run into the same problems on an a/w setup thats 300whp and a 700whp. the only difference is traction. If you do it right then it should be just fine. You just need a good way to get the heat out that you put in.

I can't really comment on such a high horsepower car, but i have had experience with a couple street a/w setups. maybe you could ask more specific questions. A general comment is to build a system where you can isolate the a/w unit from high under hood temps. Its not practical to drive around dumping bags of ice in every 20 mins. If you can get the heat out of you air efficently with a good a/w unit and then get that head out with a large front mount radiator , then your golden

 

after some research, it seems that the A/W IC get heatsoaked therefore making them a Not street friendly setp.

And after they get soaked, they tend to take a while to disapate the heat.

I have no fist hand expeirence with them sooooo i really have no actual info to back this.But this is what ive found.


Edit:And 750hp on the street probably wouldnt be to cool either.

this is not nessasarly ture, if you plan ahead alittle you can make a very streetable a/w setup.

this is ture, that is why one must isolate their a/w unit as much as possible , and use a large enough front mount radiator. a properly designed setup can work as efficently as an air to air

 

Have you seen an AWIC work fine on the street?

um.,. yes.

There are alot of people that use a/w setups, its not too common on hondas because there isn't a whole lot of space under the hood and air to air is usually much more simple. I have personally seen many sucessfully street driven a/w setups.

 

cody at lovefab up in MI designed a turbo setup for the nsx with an a2w setup. He has videos of the car being flogged on with minimal heat soak

 

i ran air water last year and when i drove it on the street, i could get on it and have some fun but i only did it in my lowest boost which was 20 psi. Never had any issues with that. PWR 6x8 intercooler

 

generally, what kind of IATs did you see over ambient?

 

i dont know on the street but on the dyno at the end of the pull it would be around 75-79 degrees

 

75 over ambient?

 

I have a friend who runs a vortech s/c on a GSR with a liquid to aid aftercooler and a radiator out front. on a 75 degree day we saw a 90 degree IAT with the aftercooler water pump running. Don't know what it was with the pump off.

 

people need to state iat and ambient - just iat means jack

Unfortunately your engine does not feel the same way.

 

LOL.

IAT is everything. Ambient - THERE AINT **** J00 CAN DOO ABOUT IT.

 

No - you cant know how well the I/C is working without knowing ambient. IATs could be at 75 degrees, but ambient was 0!

the efficiency of the setup is dependent on how well the system is designed. you can't run a 700whp setup through a small eclipse side mount intercooler. Just the same if the heat exchanger out front is large enough and the a/w intercooler is properly size and designed to flow for your power requirements, then the setup will be just fine. If a system is designed right then the only things you need to worry about are heat soak when you park the car..

but for you i would suggest not to go a/w. Its clear that your unsure and that if you did go a/w and it didn't work out then you would come runing back here and say how wrong we all are and that a/w sucks. Just go air to air.

 

a/w ftmfw!

key areas to address in any a/w setup:
-complexity & piping lengths...the shorter the better
-keeping the charge temps down to start...aka cold air intake pre-turbo
-keepin you i/c core isolated...once the get hot w/o a decent radiant setup it will remain hot...common problem w/ a/w is that people dont set it up properly
-good heat excanger w/ a switched shutoff for the tracks so your not pumping you ice cold water thru the entire system only the isolated i/c core
-pump...it has to flow a decent amount...dont worry to much about pressure...ive run 1/2 & 3/4 lines and havent seen to many changes
- the a/w i/c core itself can be much smaller than the standard a/a units making the effective area after the turbo much smaller = increased throttle response...also these need to be very good at dissapaiting heat...ive seen spearco cores work extremly well and im currently running a denso core...which is alright but not thee best it could be
