I installed a heat exchanger on my Escort last weekend. It is exactly as described above. I have pictures, but don't have internet access at home (damn DSL) to upload them.

So far, I am impressed. I have not relocated the FPR yet, but I intend to as soon as I figure out a way to effectively seal the end of the fuel rail where it is bolted.
In my Escort, city driving only would yield 23 mpg. Last week, when I filled up after only city driving, I got 22.91 mpg. That's pretty crappy for a 4 banger in my opinion. When I filled up yesterday after a week of only city driving, I calculated 29.62 mpg. I gained nearly 7 mpg. Not too bad.
I've only had it on a week and will be putting it through the paces over the next two months. If all works well, I might just install one on the 4Runner!

Once again, THANKS, GADGET, FOR THE GREAT IDEA!

congratulations! i'll be installing mine in the next few weeks. if i can get even a 1-2MPG increase i'll be happy! my feeling is that the highway is where this device would really shine, given that the coolant is already at its highest temp.

Alan-

Please post pics when you get a chance, I'm very interested.

Thanks

My TDI Jetta already gets 52 MPG on the highway - and its diesel. If VW ever decided to make a diesel/electric hybrid then we'd be looking at way higher numbers. Yes - there are cars that get great mileage out there but no heavy truck with the aerodynamics of a brick will get close. Be realistic. Start with simple things like synthetic fluids and check your tire pressure - and take it easy on the gas pedal.

Pics and instructions for the Fuel Atomizer and Heat Exchanger would be great! Anyone already done them both?

Very interested in these 2 mods. I'm not overly interested in HP gains. If that was all I needed (quick 0-60 times) I'd have kept my Katana. I'd be absolutely thrilled w/ 20-22 mpg hwy w/ my Runner. I'm also planning on a flex-a-lite elec. fan for a little more efficient use of what little power the 3.0 has.
Think a guy could consistantly gain 4 mpg?

we'll see . . . .

Haveblue -

do you have a parts list for the compression connections you used in your heat exchanger?

For my heat exchanger, I used 2" copper piping and 7' of 3/8"copper tubing. I cut a 6" section of the upper radiator hose and inserted the copper piping. I coiled the 3/8" tubing around the pipe. I re-routed the main fuel line from the filter to the copper tubing, then from the tubing to the fuel rail.
In a perfect world, I would have removed the FPR, but it's attached in such a way that it would leave a gaping hole for fuel to spill out. I need to seal that some how.
I insulated the whole thing with header wrap and Thermo-Tec adhesive backed heat shield.

Keep in mind, I installed this on my Ford Escort.
If all goes well and I don't experience and vapor locking or any other adverse effects, I will probably make another one for the 4Runner.

I will upload pictures soon, hopefully. I am waiting for my DSL hardware from Earthlink.

Have, when you do your write-up, (you are meaning to do one, arent you?) please remember to use VERY small words and not to abbreviate. There are some on this forum (me) who are interested in trying this on their rigs.
While I'm capable of chewing gum and walking @ the same time, trying to chew gum and work on my 4Runner @ the same time would be a death sentence.

HaveBlue

I will do a write-up if and when I install one on the 4Runner, but for right now, I have only installed one on my Escort. I don't think an Escort write-up in a Toyota forum would be a good idea

Actually if it's not a problem I'd like to see a picture of how you plumb the copper line into the fuel line at the beginning and end.

I just wanted to let everyone know that my last tank of gas, with my wife driving it by the way, I got 16.1 mpg. This is with the new SMT-6 partially installed too, and no professional installation either. I'm hopig that once I get it dialed in, I'll be able to get better gas mileage on one map and better power out the other map. It's been fun!

Alan, have you done the writeups for the fuel atomizer and the heat exchanger yet?

Chris

Any additional info on the fuel atomizer and heat exchanger for the 3.4L???

ravencr

I just got mine in the other day, and I plan an install pretty soon. I'll keep everyone posted on the progress.

a bump from wayyyyy back. hey blue have you finished the heat exchanger on the runner yet? if not would still like to see the pics of the ford.

RavenCR and/or HaveBlue:


Any news or results that you can pass on concerning the Fuel Atomiser or the Heat Exchanger?

p5150

holy sheite - its not easter yet man.

No complaints though, just thought Id post some legitimate ideas for better fuel economy:

KN filter,
headers with an effecient exhaust and better cat,

AFTERMARKET injectors like bosch, etc. They have a finer spray pattern and atomize the fuel better than 80 something Toyota injectors.

P/P manifold/head
Thinner tires or higher tire pressures.
Lower the truck
Put an airdam on the front of the truck
Synthetic oil/ gear oil
Wax your ride to reduce drag
Lower your tailgate if equipped
Take your hubs out (unlocked)
Good spark plugs (splitfire plugs are BS)
Aftermarket ignition.

Larger injectors are a waste of money even if you are looking for power. The only reason you should ever need bigger injectors is if you are going forced induction.

I guess I can give some testimonies on this product.

I originally purchased this unit for my honda accord. I only hooked up the PCV part of the unit due to the fact I had fuel leaks at the junctions on various occasions. I'm going to make another attempt to work this out again come springtime.

So far, I've gone from 36 on the highway to "on average" 54-60 mpg. I say average because this units seems to work much more effiently on hotter days. It seems that the hotter the outside temperature, the better the milage. I'm not the only one to comment about this. All of my best milage runs were on 90+ degree days.

The best milage I've ever pulled was 74.5. Yep, you read that right. It normally takes 100-120 miles for my guage to move from the full position. That particular day it didn't move unitl 163. I thought my fuel sender/float was toast by the time I hit 145 and the guage didn't move. The best milage I could ever achieve on that trip, same temp, driving style and everything, without the Fuel atomizer was 51, so thats pure proof to me. The temperature that day? 100 degrees the whole entire trip (243 miles).

After my constant blabbering of these figures, my parents wanted to give it a try on their camry. I've taken that car on several of the same trips as the accord so I knew what kind of milage I can pull out of that car before the installation. Milage went from 35 w/out fuel atomizer to 52 w/ atomizer. This is pure freeway driving like the accord. Temperature that day was about 86, so I will be able to pull more on a hotter day, we'll see come summertime.

I'm toying with the idea of routing some of the hot air from the radiator to my air filter housing to see what effect that will have on the milage. Lost of experimentation this summer. I'll post results if anybody desires so.

Remeber that I only used the PCV part in this experimentation on both vehicles. I know for a fact if I get the fuel end of it working properly, I'll pull even better milage than the above.

I've purchased all of my units brand new on ebay for $75-$85. That is considerably cheaper than through the dealer. Just keep an eye out, they pop up from time to time. I alreay have one waiting for my 84 EFI 2wd pickup, but will not install until after the rebuild is done.

Intresting reading.

85sr5toy, when you say, you just hooked up the pcv part, you mean to say that you had no fuel what so ever going into the unit?
