Race gas or meth?

ride_the_pony69 · 07-13-2006, 03:58 AM

Hey I wanted to know if anyone thinks I should just use race gas or just meth for an fp red? Has anyone used race gas with a red yet? The highest I have seen with meth on an internal wastegate was 485whp and 507whp with meth on and external gate. So I just want to know how much more hp will I gain from using race gas?

Both, they each have thier benifits and draw backs.

Ok well I know both, but should I do just meth or race gas and meth?

Having a race gas map will allow you to eliminate a meth pump as a source of possible failure. On the other hand, meth has it advantages as far as cost/longevity with its use with pump gas. It depends on your goals. Glory runs at the track? Do a race gas map. If its consistent high power useage on a more daily basis go with meth.

I went through the same situation, well minus the red. My thoughts are if you do a lot of daily driving and still want that kind of power go for the meth. If you don't and have racegas widely available the do that. When I got tuned, there was no way I could get the injection kit and installed in time so I just went for the racegas map. I took that and reworked it into my alky map. They both yield more timing and leaner mixtures, also more boost. Racegas is cheap in the short term, but meth/alky is way cheaper come long term.

meth is going to be a lot cheaper and a lot easier to run day to day. if you just want a map for special events (drag's, hpde's, etc) def go with race gas.

Pump

Meth and Pump

Race Gas

Meth and Race gas

(if it's even possible never really thought about it or research'd it).

4 maps

actually depending on how high the octance of the race gas is, running both isn't actually better. meth makes it like running 112 oct i believe, so running higher octane (above 112) wont help.

Meth/WI will help any setup no matter what fuel is used.
The cooling properties of the Meth/WI will allow you to get a denser charge into the cylinder. It is not only the octane bump that helps make power with meth/WI.

Meth for sure....

Race gas is more expensive, but like others have said...it depends on your wants/needs.

I would go with 4 maps like The Clap posted...

phil is injecting windshield washer fluid through his hydramist setup and just tuned his car as if it was c16. we're getting one of his next hydramist setups, hopefully before the shootout.

Thanks for the info guys. I think I will just have a pump map, meth and pump map, and meth and race gas map.

just an observation, there are way too many people on here running meth injection like its a bolt on. most dont understand that if your system fails, clogs, a hose pops off, or runs out, your motor is most likely going to be done for. depending on the tune and situation of course.

if you get a kit, do your research, get a quality one that fits your needs, AND GET A FAILSAFE.

im currently running a coolingmist trunk mount kit with variable controller and an Aquamist DDS3 failsafe.

And I see WAY to many people say **** like this. I have personally seen 3 WI kits FAIL in 3 different ways. Guess what if you use the OEM ECU or a Utec you WILL feel something wrong. And guess what, as long as you don't try to drive off that wrong feeling the car WILL be fine. Failsafes are a great waste of money, unless you are an idiot. Think of how many kits are on other makes of car and have been for many many years. About the only thing you really have to worry about is the WI tank siphoning into the intake. As long as you have a check valve that won't happen.

^^ ditto. I'm using the SMC kit and only bump boost 1 psi and timing an additional 2*. I didn't trim too much fuel just for my daily driving style. If it were to fail or run out, I wouldn't have any problems as my car would just be running a little bit leaner but nothing unsafe, and the majority of timing added was around 3600+rpm's. Stay out of that and your fine, even if I was to not notice it for some freak reason the ecu would take care of the extra timing as it would pull the KC as soon as a hint of knock was detected. The guys in Alaska run these kits with their stock ecu's or just an AP OTS map to make up to the lack of octane up there. As long as you use your kit safely and have a seperate map for racing you should have no problems. I have read about failsafes failing also so you can't count on that to 100% save you.
