Propane finally installed

[detpac]

Propane went in finally today. The actual hardest part was trying to put in the spray port. With the GT Pro Y-pipe, the metal is not very thick and therefore had to be built up. Other than that it was pretty simple. No testing yet as I just got the tank. I don't know what is up with El Paso, but no one carries the 5 lb. bottles of propane. I had to buy the 18 lb. one for outdoor grills. Not a big deal. I will be testing soon and tuning it to my liking. I will update you all as I go.

Cool beans David. Let us know how it runs and what you boost up to.

Bwhahahahahah, 18 lb tank. No weight reduction there.:D

[detpac]

I can see it now.

"No officer, I'm going to a cook out. I just needed a tank refilled."

[last_in_line]

ya hehe where are you going to put the tank

[detpac]

Mounted in the Back seat right now. I have got to find a suitable mounting place and bracket.

[detpac]

Took it out to test and Made a huge difference in boost. Clutch is slipping so I could not get it to hook up very well but man is it nice. I had the boost set to 18 lbs and got a little scared. Anyone know how to adjust a clutch (not clutch pedal)?

Here's some pics of my propane kit installed from DR.

Perfect timing since gas prices will be skyrocketing.

It doens't replace the fuel, just injects in right before the intake in the y-pipe.

Race gas for Super Unleaded prices:D

Is the propane just a octane booster?

[red3kgtvr4]

No. It injects a few inches before the throttle body in the y-pipe and cools the exhaust gas temps which allows you to run more boost. I'm at 19psi right now with no knock. :D You're supposed to be able to run 5-7 more psi from the point where you started to knock. I should be able to turn it up a bit more, but I need to do some more logging first.;)

It is a fuel that acts as an octane booster and cools the intake air. More boost. More power.

Gutted precats on your 96?

[red3kgtvr4]

Cat? What cats?! :D I've got a Stillen dp and a rear precat eliminator. Pics on the link in my sig.

CEL? I got the ATR DP but never gutted the precats.

[red3kgtvr4]

No CEL here. I've had it that way for a while - no problems.

You suck. :)

[red3kgtvr4]

Are you sure the CEL is from your cats? Do you have a logger to check the code to be sure?

Actually, there's a recall for the OBDII ECU where it doensn't pick up all CELs for emissions. That's why SOME have it and SOME DONT. I just don't wanna do it and get a CEL and can't fix it. :(

[red3kgtvr4]

Never heard about that one. Is it a recent recall. When I had my TC checked out, no other recall pulled up on my car. I think I'll leave my ECU alone for now. Having a Mitsu dealer mess with my ECU is the LAST thing I want!:D

Back on thread topic...
Any more propane install pics?

[detpac]

No.

[bishi2NR]

thats a sweet set up, i checked out your site. have you timed any runs in the 1/4 mile?

If you're referring to me... no times - yet. Going to be doing a rebuild in Feb or March with forged pistons, DR stage 3 heads, possible a mild cam grind, DXD-F clutch, 3rd gen lifters, etc...
Of course all this will be documented and added to my site. :)

After everything is broke in and tuned, I'll be looking for low 11's. I'll post slips when I get 'em! ;)

What turbos and what fuel?

[red3kgtvr4]

Phantoms from turbochargers.com and 660cc's w/ the ARC2 and 87mm mas. There's pics of everything on my site... old and new comparisons of turbos, injectors, precats...

Just to clear up some misconceptions about Propane.

It is a Fuel, unlike Nitrous.

It adds NO power itself, it just allows for higher boost on pump gas.

It Does NOT lower intake temps. It was thought early on that it did but accurate tests with temp porobes proved otherwise. Now I knwo you will say "Expanding gas cools etc" By the time it reaches the injection point it is not cold. Tests have proven no cooling to the intake.

Why Propane?
Very High Octane Rating of 110+
Allows You To Run Higher Boost Levels Without Detonation
Very Cost effective. One $2.50 Propane Tank fill up lasts many gas tank fill ups
It's like running Race gas on the street....Except it only costs $3 month to use!


For Gasoline Forced Induction Vehicles:
Higher Octane allows for higher boost pressure
without detonation which is the leading cause
of engine failure in F/I setups

The Gaseous/Vapor state of Propane forces a
better distribution of Air/Fuel charge greatly
reducing "Hot Spots" in the combustion chamber
lowering the chance for detonation

Propane can and has been used succefully in NA setups when High CR and timing calls for High octane fuel.

Doesn't reduce intake temps? Similiar to n20, it comes out of the bottle very cold, why wouldn't it reduce intake temps?

Because it does not come out of the bottle as cold as N20 and By the time it reaches the injection point it is not cold. After traveling 15 feet of line it is no longer cold. Hell, I sell it so If I could get away with saying "Cools Intake" you know I would back that up. But it doesn't so we don't sell it with that assumption.

when injecting into the ypipe it doesnt have far to go tho. even then it doesnt make a difference in temp?

The Y Pipe is where it is injected. Doesn't have far to go? That is like 15 feet.

I have tested this with a Fluke temp probe. If anything there is a 1-2 degree drop in charge air temp. That is all.

Benefits of propane are:

Higher Octane allows for higher boost pressure
without detonation which is the leading cause
of engine failure in F/I setups

The Gaseous/Vapor state of Propane forces a
better distribution of Air/Fuel charge greatly
reducing "Hot Spots" in the combustion chamber
lowering the chance for detonation


Heck, you think I would debunk the temp thing if it was not true? It sure don't help sales to tell everyone it don't lower temps as previous thought.

[last_in_line]

gawd damn what a bummer. thats one of the things i liked about it even more than the octane boost

[last_in_line]

but still like you say theres plenty of reason to use it.

[red3kgtvr4]

Hey DJ ~
Any pics of your install?
