has anyone really messed around wih the methanol injection into the intercoller set ups...


i dunno im just looking for info on it...like that and a pulley would u need to tune???

is it useless to do?

i guess im lost...can anyone help me???

 

Not worthless at all. If you run straight alky it will richen your a/f but that's not a problem. It will allow you to run more timing/boost on pump gas for sure. I have a system on my truck and wouldn't go without it unless I was going to run straight race gas all the time.

are you talking about something that would spray onto the heat exchanger??? i think that it would work, but not that great because you have coolant flowing though, and the short period of time that the coolant is in the heat exchanger a blast of cold gas really wouldnt cool it down much???? i might be way off, but thats just the way i see it... something that is an air to air intercooler it works great, because it can cool the air much more effectivly..

 

he means injecting it into the motor through the intake.

 

We've done alot of the "meth" kits and they work wonders on the "heaton" and on Whipples (or KBs), on both the Lightnings and the Cobras. The water/methanol not only cools down the exit temps from the supercharger, but it also increases the octane rating of the fuel. This results in lowering the cylinder temps and allows for a lot more timing without the fear of detonation. A 30 to 40 HP gian is not unusual on a Lightning. Horsepower gain will vary depending on how much boost you're running, the amount of additional mods on the vehicle, ambient temps, etc.

 

There is an article on water/methanol injection in the July 2005 issue of Popular Hot Rodding. PHR used a '94 KB supercharged Lightning as their test vehicle.

 

now is it goin to have to require remaping???

 

Yes and no. To get the gains out of it you'll want to add timing and/or boost, which will require re-doing the tune. Just installing it on the truck can be done without touching the tune. It will show a richer a/f when under wot with the alky, but doesn't have to be re-tuned for that.

so it would be smarter to invest in a tuner at the same time wouldnt it?


yeah there arent enough hours in a day for me to research this...

 

My thoughts are for any decent mods like a pulley, alcohol injection, full exhaust, etc. you need to get the proper tune. They go hand in hand. Any of the handheld tuners work great, and have different advantages/disadvantages. But with any of them I'd hook up with a good Lightning tuner to get a custom tune for your mods. It is worth it.

yeah but its that$$$ thing that kicks my *** right now...i werk and werk and werk....

 

As mentioned in a previous post is that it will cool things down. We learned very quickly when running a stock L on the Dyno, as the temperature increases, the stock "software" begins to pull away timing to prevent detonation.
HP dropped dramatically from run to run on the Dyno.

Is the HP gain from running extra timing? I was at the track last week and with pure 100 unleaded in the tank, I ran 21 degrees timing and didn't feel it picked up much over the 18-19 degrees I've run in the past.

 

Did you log each run? Depending on how a few things are set in the two different tunes you might not have gained any timing. And at the same time the A/F may have changed. 2~3 degrees of timing wakes my truck up big time at the track.

 

What kits is everyone running for there "injection" setups? And wasn't methonal suppose to be very corrosive to the whole intake system(blower/intercooler)?
