Yes it is! The tank is a lot stronger than your Gasoline tank and Gasoline is also flammable, LPG tanks a really overbuilt

 

So how would running a system like this effect tunning. For example if you were running a hondata setup. Tune for low boost and 91 octane? Then tune for highboost with propane and 91 octane?

 

boosted 92- your buddy has a 250 shot on pump gas made possible through the octane increases provided by the propane, correct? could u shed some light on how to calculate the correct nitrous/propane ratios? i have been wanting to try this for quite some time. do u know anyone else that runs nitrous with propane that could provide tech info on their setup as well?

There is really no Propane to Nitrous ratio, you just have to start out with to much propane and tune it down from there. Its all about datalogging!

I remember when he first introduced it a few years ago.

 

how do u know when to stop leaning out the propane mixture? is it similar to tuning with fuel jets? do the plugs look any different? is there any method that you would recommend to do this easy/safe?

 

The way I would do it is take it to the Dyno. Or if you have a nice datalogger that can show EGT, A/F, knock sum, timing advance etc. Just use your datalogger to moniter all of the above and tune from there. Really not that hard. If you do not have a Datalogger take it to a Dyno and tune it there!

this is very interesting. i am actually planning out a nitrous d16y8 crx and now i am considering propane injection. i've got a couple questions, like can the zex air amplifer be used to inject propane? also, how would the propane be actiavted with a nitrous kit like zex?

thanks

The only thing that might hold you back with the ZEX Amplifier is the pressure that propane is injected. Nitrous is not regulated in most cases when its injected, So you are looking at a 1000+psi when nitrous is injected. Propane is injected at abou 90-100psi so the amplifier would not really help you. You can use any simple switch to activate the propane. You can tap off the TPS sensor wire that the ZEX kits uses. you can use a basic window switch that will activate the nitrous at any given RMP point.

I read through the thread and maybe I missed it, but are there any detrimental(sp?) effects involved with propane injection??

 

for those of you that have tuned on the dyno with propane... did you see power gains outside of what u expected to get from the increased boost/ timing? did anyone ever see low egts, high timing, high boost, and record a power loss? the reason i ask is because ive been debating the same thing on g2ic. some think that the propane will make the mixture so rich that the engine actually loses power. i think the trick to this is just getting the prop injection on point, but u guys that have done it let me know what you think. thanks again.

how did you guys connect the propane tank to the nozzle/jet?

I was ready to order this until I saw this.

For safety purposes use a CLOSED LOOP BOV ONLY to keep unspent Propane from entering engine compartment.


Most of use have open loop BOV's so this really isn't a good idea having a highly flammable gas in the engine bay.

 

WOW...thats a good heads up!!! didn't think of that.

 

could it seriously matter that much? if you were boosting and injecting propane, then you would hopefully be moving pretty fast. a lot of air would be moving thru the engine bay and under the car. it seems like the propane would disperse throughout surrounding atmosphere quickly and be extremely difficult to ignite unless one was trying to. what could possibly go wrong? in theory, it sounds dangerous, but can anyone substantiate this with any factual evidence?

point made but propane is too dangerous to take that chance I rather be safe than sorry propane is more volatile and flammable than gas I wouldn't do it on a open bov its not worth it I value my car more than 20hp

 

this is awesome. lets see some pics of setups!

They only way this will even matter is if you are injection before the BOV! if you are injectiong into the TB it will not matter.

I can still see it happening. TB suddenly closes blocking the left over propane from going into the Intake manifold. Thus being released by the BOV.

 

So recirculate the BOV... not a big deal to do. I do it on my civic & Talon (even though I have a GM-MAF on it now) because I think BOV sound = annoying. Seems worth it to me to gain major power!

Or at the very least plumb it out of the engine bay.

Not that easy to recirculate an HKS SSQV. If you have seen it, post pictures.
