Ohhh, I forget that people only have access to 91. I was wondering why you and fromWRX were using 91. I was thinking that it might not be worth the extra money or something....damned noobs!! Thanks Guys.

 

Those aren't alky supporting mods - those are big power, big boost supporting mods. YOu'll need them on race gas for the same reason as meth. In fact, you need them moreso, because you won't be getting the cooling effect of alky/meth when you use race gas. YOu might also need injectors, since alky/meth significantly reduces injector duty cycle, whereas the race gas not so much. You'll have to watch the IJDs and make a choice based on the percentage you see. Spark plugs will need to be copper "8" heat range and probably gapped tightly unless you get an ignition amplifier (e.g. HKS DLI2), because the big boost will blow out the spark otherwise. The FMIC will be needed due to the extra heat generated by running such high boost - the stock FMIC will lose efficiency and heatsoak faster.

There is a reason to do both - I thought I said that. You would run alky daily with a normal alky tune, then at the drag strip you could toss in race gas with the alky and run a full-out ***** to the wall aggressive tune. THat's what I'm doing - I have 4 separate custom tuned maps from Al for 3 types of racing + daily driving.

 

Interesting. I am just afraid of something going wrong with the alky. Who has the best failsafe out there? Isnt there one that actually prevents high boost when a problem arrises?

 

Ditto...I was thinking about having my kit removed during my turbo install this week. I have heard to many horror stories of pumps failing. Who makes a good failsafe system for alky/meth kits?

 

this guy still has no idea what hes talking about. doesnt understand whats going on.


running higher boost or agressive timing and such, you need higher octane to not blow up.

alky or meth, provide cooling, and the effect of higher octane, SO YOU DONT BLOW UP.

HIGHER OCTANE GAS, (racegas) 100+ octane IS WHAT YOUR GOAL IS.

meth or alky is just making your ****ty pump gas close or closer to the same effect as racegas. making your 91-93 octane act like 100+ so you dont blow up, so you can run higher boost, more timing.

these guys explained it a couple times and you still dont understand and i dont know if what i said will help either. sell your evo asap, you obviously dont understand.

OR make a phone call or talk to someone in person so they can actually explain so you can understand.


sorry, and good luck

 

IF YOU HAVE ACCESS TO RACE GAS, USE IT. that is the safest way. no matter what gas you run there still will be limits to how much boost you can run. injectors, fuel pumps, your engine, a tune all are factors in how much boost you can run.

alky and meth can run out, and when they do your car doesnt just stop like if you ran out of gas, you have a very high chance of doing damage if your driving aggressively. if your racegas runs out your car runs out of gas, its fine.

if you run out of alky and meth at full throttle you run the risk of blowing up, if your running more boost than pump gas can handle.

 

Hey neighbor...lol I live in glendale heights, right next to addison....there is actually 110 octane like down the street from my house which is probably not too far from yours! why settle for 100 octane...lol

 

There are dangers and risks associated with running alky injection, but randomly running out while boosting is not one of them. That is the least of the worries, because there should be an indicator of when you're low just like on your gas gauge. My SMC kit displays a low light when I reach a 1/3 tank, which is plenty of time to refill or just not boost. It's not like I'm going WOT and all the sudden I run dry...

The main worry is a pump failure, which is what he said in his last post. If the pump fails while boosting, then you likely detonate the engine to death.

 

Because 110 is leaded, and the power differences would be negligible.

 

That's the only problem that I have with Meth/Alky. I have already had a problem with my control box not working which caused serious damage to my old engine a little over a year ago. I'm having my SMC kit removed for now but would like to know if there are any proven failsafe systems out there for future use....maybe? Please excuse me for getting a little off of the topic.

 

Snow Performance seems to have one of the best failsafes. Anyone with more info about that?

 

what im saying is there is risks when running those systems if you have access to race gas perminately, USE IT.

 

What is the highest octane gas you can buy at a pump that is unleaded?

 

It's usually 100, but it depends on your area. There is a site that shows all the gas stations in every town that sells GT100. There are 4 in Denver, 2 of which I have used, but I don't have close enough access to use 100oct 24/7. You can probably find a place near you if you go to that website. I don't remember the URL off-hand, but you can surely find it with Google.

 

Snow performance for the money have one of the best failsafes out there, if anyone wants to know anything about them pm me, I happen to know a thing or two...
