Supercharged CRX

[OBD1 Kenobi]

Fock, sorry I can't resist on this topic. I've read a lot of JRSC customers didn't have a good experience when ordering coz peeps at JRSC suck. but the unit itself is great.


I wish my car ran crappy... My car runs quick being "almost" stock. I have turbo parts laying around, but I really don't wanna end up having problems with my engine. All set, I have a Z6 head and 14B turbo, HF mani, IC and other shizzle that can go on. I DON'T have EMISSIONS.. car is registered in TN so, no inspection, no emmision. I love it, but the car is running great, perfect set up for autoX... Maybe I hook up this Nitrouswerks shizzle and blow it up then start over.or Anyone selling a rex that needs some werk for cheap?!

ooo obd will you let me register my car in tn?
youve got an addy there or something?

see I heard jrsc's suck.  Its because they get themselves too hot.  If you dont' run an intercooler with it, it can much more easily burn itself out.  Where as a vortech has a better system as it pulls from the front of the engine, charges there, and has a short run of pipe to the intake mani allowing for a better intercooler design(water to air) and also the heat generated is kept away from the intake mani.

water to air intercoolers are not practical for daily driving, coz you'd then need an auxillary system to cool the water down, perfect for the quarters though, coz you can jus dump ice and water in there and run! Also, another thing about intercoolers is amt of piping and pressure drop. Basically more piping means more surface area to pressurize, the longer the lag.

[dilbert]

ok, well maybe you like cheapo air to water coolers! lol, cause the ones I have seen have a small electric pump that is turned on or off by a switch that you have inside the car but it flows water through another air to water rad.  but its nice cause it doen't have the problem as you stated with the amount of piping and also is easier to install.

[OBD1 Kenobi]

that's what I mean you'll have another intercooler cooling the intercooler............... HAHAHAHA that's good... more weight...

[sxy_rexi]

omg youre really gonna have to worry about those extra maybe what 5 lbs in order to improve your 1/4 by what? maybe .005? maybe.. if youre lucky

yes every ounce you take off adds up
but whats 5 lbs if you can get it to go faster in the long run?



actually I know absolutely nothing about this turbo shit yet.
but just feeling the need to start arguments recently  :roll:

why dont you remove that huge gas tank, lexan the windows, or do a fiberglass one piece front and then you can worry about an extra 5 lbs.
then the percent weight will actually change more dramatically and really affect your time more.
2100:5 lbs or 1800:5 its a lot bigger percent drop

[OBD1 Kenobi]

anytime you can save weight, save it. But the idea of an intercooled intercooler jus doesn't appeal to me. it's too complicated...


calculate cooling efficiency of the air to water intercooler to the output of the type of turbo... then calculate the cooling efficiency of the intercooler/radiator that cools the water that cools the air charge from the turbo....

so in layman's terms.. you have the air cooling the water that's cooling the air.. why not jus have the air cooling the air, and save weight on the water and misc. parts.

if you really need cooling, rig up an IC sprayer (stock on evo's) but go one step further and mix water and alcohol for max cooling. Of course ya gotta be careful, alcoholo is flamable, but it sure does evaporate fast.

[dilbert]

The nice part about the air to water to air cooler system is that it tends to stay colder.  and will actually make more of a drop in temp than a air to air.  plus the fact that the air to water part that goes between the charger and intake is much smaller and since the piping is less distance you can create boost much sooner as you do not have to actually compress the same volume of air.  The weight thing is bad though, but the weight woudl be more than 5lbs, it woudl probably be more in the range of 15 to 20 if you figure a rad full of water, lines full of water, rad weight, rad weight(yea, two), small electric water pump.

[OBD1 Kenobi]

true true, but the IC sprayer will work jus like it. Dilly your right, the pipes won't be long.... I dunno, I've looked thru these when I was thinking of an upgrade on my dsm. The only thing I did is the sprayer... it works pretty good. oh, yah, cheap too.

[cottagecreep]

Or you can just use my fat ass air-air IC, or run a complete custom one from my cores

[silverkorn]

in the end the water-air IC will always be better, thats why drag cars use them. but like knobi said your now adding more weight. yea it may not be that much. in the end if you want to have a higher cooling effect you could just setup the CO2 N2O IC sprayer on a air-air and now you get the same thing of the water -air. only problem is that people who use the sprayer often get a hot spot since the air temp has dropped so rapidly that the car will suddenly run lean for the lack of fuel.

SC? I wouldn't do it again...I am a Turbo man now!

[super-rex]

I have ran my car in the 1/4 mile and it ran a 13.92 at 101.  Would have bee faster but I'm not going to lie if I could of driven it better and not spun through most of 2nd and the beginning of third.   If your looking to do the same setup I could sell you mine because I want to do a little different setup with my car.  My kit only has about 900 miles on it and I'll part with it for bout' $2000.

[dilbert]

but my question is, why after only 900 miles are you getting rid of it?  what made you change your mind?  Thats the thing that is against me on going supercharged.  becuse I see this all the time, people just then say, "I want a change"  that doesn't make sence, you have only gone 900miles....
