Wow.. One of my ideas inspired a veteran z-racer..... I feel so special.

 

if you really want to hook some sort of ac motor for minor cooling effect why not get the vapourator off a a small 90/120l chest freezer. from there this runs electrically not mechanicly so does not sap the engine of power. The only problem would be the location of the unit depending on the size of it and remember to generate cold air the unit will generate heat so will need to be in a well ventilated area. you just need a power adaptor running that can handle it

 

I think this should be considered / calculated before physically doing this "Icebox Intake." If the motor pulls more air than the condensor can cool... well, you get the idea...

 

all that work when u can just do methanol injection my next upgrade

 

this whole thread reeks of the "e-charger", and we all know how great those are.

 

hmmm.....whats an e-charger?

 

electric "super charger"

basically a blower motor in your intake that doesnt do squat.

 

email... e=electric / electronic.

electric charger = rice

 

to late i win!!!

 

take your fuel injector cooler, make it bigger.. and you have the turbonater, no self respecting car enthusiast would ever buy one.. jperkins.. you might consider a swap if you wanna make your car faster, there are a ton of nissan guys in the OKC area that can point you in the right direction, an SR swap maybe

 

That's not the right direction. Well... at least you kept it Nissan.

 

now there is a idea, i can get those anywhere, and run an inverter to power it, they really dont take that much juice either, and i can get a really small evaporator. although this type of thing would work 100 times better on a turbo, where cool air rules. my n/a application wont show as much of a differance. but still interesting to try at some point

 

 

Fun thread. As long as "out-there" ideas are floating around, here's a truly awful one to throw around, just for fun on a Friday :
Buy a dewar flask (~$300 new, http://www.coleparmer.com/catalog/pr...x.asp?cls=2645 , or less for "used" on ebay or whereever) and use liquid nitrogen as the source for the cooling.

I guess you'd have to use a new IC or other apparatus, as any remaining water from the original system would freeze and block the whole thing, probably causing a rupture as the Nitrogen boiled), and you'd need all solid tubing for the supply (any rubber would freeze and shatter), and you'd have to have very good venting for the boiling. No loss of power from the engine to run fans or pumps, though. And the vapors coming off would look very "Back To The Future". ("Don't take the Z over 88 mph, Marty!")

Other nasty downsides:
Risk of cryogenically burning yourself and losing flesh when you fill up.
You can't store liquid Nitrogen outside of a cryogenic industrial facility for more than a few days, typically.
If your venting is wrong, the flask and/or cooler will rupture or maybe explode, and damage/destroy whatever's around it.
If you ran it on the street, you might have to run a placard on your car for cryogenics, and maybe get a CDL with a HazMat endorsement.
It might be so damn cold that the whole cooler assembly would ice up, so you'd have to regulate the Nitrogen supply to the cooling system very carefully.
You'd have to fill up at the local University physics department or welding supply house (same PITA as nitrous) every time you wanted to use the system.

I'm sure there are other really bad downsides to this idea. Add to the list for fun!
Okay, guess I better get back to work.

 

that e-charger looks like it'd break. but the idea wasn't for the air pressure increase or any sort of blowing effect. it was just for the colder air from the start. figured it might help people who live it 100+ degree places.

 

All these ideas are mostly useless on our NA cars. Not because it won't increase the density of the air at all, but because our ECU's won't care much. They use a fixed fuel map based on the reading from the AFM resulting on the physical position of the AFM flapper. This is why MAF and MAP sensor upgrades are popular. They actually measure the air density.

Now the cryo idea has significant merit on turbo cars. I'm not sure I'd go to that extreme, but I have seen a Z33 TT on the dyno make 60 additional whp with a CryO2 system converted to use nitrous instead of CO2 with absolutely no additional changes to the car.

 

I would certainly hope that before you start looking at doing a whole lot with an N/A you'd upgrade the fuel injection. This theory is best executed with current technology in mind, not 60s EFI.

 

ive never upgraded my n/a injection at all other than the throttle body!! i can only wish for money to upgrade parts in that system. for crappy fule injection, it does alright, all ya got to do is fool it!

 

Fool it nothing. If you tune it properly through the AFM there's no fooling it to do anything. The stock EFI has plenty of room for adjustment, you just have to know how to make the proper adjustments to get it there. In the end the only problems I had with the stock EFI is the damned wires. The wiring is so old it's just worn out and ready to fall a part at a moments notice.

 

One of those "red neck" (one word or two?) tv hot rod shows, using a new corvette, placed twin turbo's behind the driver! The distance required from the turb to the intercooler was off set by the lack of heat. The heat generated by the turbo was 1) not under the hood. and 2) The air flow produced was cooled on the way back to the intercooler. This resulted in a (if I remember right) almost 12 percent increase in turbo efficancy while cooling the underhood temp's! Just a thought! PS! Yes I am a "redneck!" (from NY?)

 

^^^ There's a company called STS Turbo Systems ( www.ststurbo.com ) that has been doing those rear mounted turbos for years now. It is indeed a very good idea... but their setups like to blow stock motors that aren't prep'd for the higher pressures.

 

At the same time, I've heard that the problem with those setups are more or less that it takes longer to spool, and the boost isn't as effective do to the long distance of having to be routed through a bunch of extra piping, and the fact that the exhaust pressure wouldn't spool the turbo when it got all the way back there. It might be wrong, but that's what I've heard before.

 

^^^ There's been a lot of controversy about their setups. But all the people who have driven one, loves it... so I don't think turbo lag is too bad. Check out their vids:

it DEFINATLY doesnt take them longer to spool, your just going to get a pressure drop but with the turbo's they use, it shouldnt be an issue. the further away a turbo is from the motor the better it spools. thats why alot of turbo drag cars/track cars use those long headers and put the turbo somewhat far away from the stock location.

 

nathavan, thats basically what ive done too "fool" it, i just did the big tb, and loosened the afm till it felt good. i really, really need a dyno tune tho, it has so much more potential left, i can feel it. then comes the big intake mani!!
