Alright..well here's my question. I have a propane injection kit. I used it on my turboed civic so I could run higher boost since the propane was preventing detonation...i was wondering if I should use the propane on my evo...or opt for the widely used alky kits...some input would be appreciated..thanks

 

Ive heard of it for Diesel's but not Honda's or Evo's

 

I don't have any real useful information to add except that my cousin used a propane injection kit on his stroked 2.3l 4g63 powered Galant VR4 with pretty good results. He ran 30+psi with the only problems being drivetrain or rod bearing related, which shows it had nothing to due with the propane just too much power.

If you can find a way to control the amount delivered, instead of it being an on/off switch it should work.

 

I think I would rather have a jug of alcohol than a potential missile of propane or NOS. Those pressurized cylinders of any type in a car kind of scare me.

 

Ya...in my civic it was just mounted in my truck..so basically..if I got rear ended I would have exploded. The proprane is boost triggered..so as the boost increases...so does the propane..but thanks for the imput

 

The alcohol functions pretty much the same. I just think for basically the same effect the alcohol seems to be the easier and safer path. It is probably lighter than one of those propane tanks as well.

 

Actually, those propane tanks are engineered with the dumba$$ in mind that tosses it in the back of his pickup and gets rearended. They're pretty difficult to get to blow up...
Otherwise, they would have devised some kind of special way or container to transport it from the store to your house because it would be too dangerous to let people on the roads with it in their cars. There are even vehicles that run on propane...

As far as weight: a tiny 10lb tank can last as much as 5 months. 3 months with constant hard driving. If you get a regular BBQ-size one, it'll last you a year or longer. When filled, the stock FMIC sprayer water bottle that most kits utilize is a little heavier than a 10lb tank.

Water/alcohol is also much harder to design maintenance-free because of the inherent difficulties that it presents. Even the best water pumps will fail, and you have to worry about galvanic currents, plugged nozzles, mold, contact electrification and such. Propane injection is as simple to set up and maintenance-free as nitrous and actually makes the perfect companion to nitrous.

I really hope that it'll catch on more, because it's really a much safer, easier, and overall better solution than WI.

AlwaysInBoost: did your friend install/tune his propane injection hisself or did he have a shop do it? I'm trying to find somebody that knows his $h|t about PI.

 

Actually the propane would be a lot safer than alchohol to transfer. The propane tanks are DOT approved, and often are mounted to the back of RV's.
The main drawback of propane is that is very hard to regulate the way alchohol injection is.
First of all it seems to only work as an on/off configuration, with flow rate determined by a hand adjusted valve, rather than a computer adjusted device. It cannot be ramped up as a function of boost. Also as a propane tank is used up, its pressure gets lower, so your base rate is less and less as time goes on until it is refilled.
If there was a system that had a pressure regulator, and a electronically controlled valve (the latter probably can be obtained, just dont know how fast they react), then the system would probably work quite well.
Heck you could use both types of system at the same time.

Again as far as safety goes though, your gas tank is far mor dangerous in an accident than a cylinder of propane is!

 

hmmm....never heard of it before.....maybe a good idea to invend one, patent it and sell it, make some big bucks LOL.....j/k ... i dont know i know methanol is good stuff.....never heard anything bad about it?? i would ask a few more tuning experts before setting it up on your evo.....good luck, lataaaa

 

he tuned it himself with MAFpro & an SAFCII.

 

the 3000gt guys have been doing it for quite a few years now.
unfortunately, the 3si.org forums seem like a ghost town...

 

I use a Water/Methanol Injection System in the past and it works just fine. But after reading more and more about PROPANE INJECTION.
I'm thinking about giving it a shot.

Some HighLights...
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

Any more INFO would be great,
Thanks,

 

You can use it but the added weight of the tank is a monster. I think this is why a lot of people opt for methanol with a tad bit of water instead.

 

added weight of the tank? one 5lb tank lasts about 3 months of average driving...
water is heavy, too... and you have to fill it alot more than a propane tank.

even the BBQ sized tanks don't weigh that much... they weigh less than a spare tire, and they'll last you at least half a year.

i think the reason so many people use WI now is because it's hit the mainstream... the word on PI just hasn't really spread yet.

 

WOW! this is interesting! $3 a month is cheap!! compare to WI! but unfortunately there is not much info here yet! anyone knows anything abt this?
