It was installed by one of the Euro…. techs prior to the last two days of tuning and is spraying through the SC. I have two custom Dyno tunes (Tony at Eurocharged) maximized for both running with N2O and the second tune without N2O for everyday use (tune currently installed) so pulling back the timing has been a challenge. We were originally going to have a dual tuned chip installed but I think the cost was an additional $900. you can ask Jake about the Chip if you’re interested. I only planned on using the N2O at the track or the occasional spirited race so spending $900 just to switch between tunes was a little high for me to justify. Running the NOS tune was not an option for daily use since it pulled the timing back too much.

Just remember you will need to pull at least 5-6° from your timing if you run a custom tune so watch you’re A/F , generally it’s around 1° of timing per 50# shot.
I’m able to retard some timing and safely run 35#-50# shot (pending on what fuel I’m running) but anything more and my knock sensor count escalates upward unless i'm running 100-104 race gas.

My times have not been posted on Drag times yet, but I have Jeff Croy’s time in my crosshairs, I’m having major traction issues between the 60’-140’ area around the time the N2O is activated. My concern is pulling additional timing reliably enough to confidently use 75#. Now I’m thinking about using H2O/Meth setup to reduce the chance of detonation throwing the 75# w/slicks for my next trip back to the track this spring. Just waiting to read up on OleDoc’s report on the Meth system he is installing before I jump in.

Good Luck
check your pm, I got ideas....

If anyone is running either nos or meth make sure to tune appropriately. Massive timing issues, and possible blown motors are very easy. You never want a dry shot with these cars.

If using nos shoot to the throttle body. We tested 6-8 different locations.

If you use a wet shot and shoot through the throttle body it will strip the coating on the supercharger rotors, that's what I've been told anyway.

lol

It was recommended to us to do it that way by renntech. I ran mine for 40k heavily modded with no problems or loss of boost.

Sorry Jake I wasn't trying to undermine your expertise on the matter, I'm just stating what I've heard.

The active agents in most fuels whether it be methanol or normal pump fuel apparently strips the coating off.

But I'm well aware your company has alot more testing and info done on the topic so if you say it's ok I'll take your word for it....might have go talk to you about this dual chip process.

Also tri zombi thanks for your info man, just curious how to you adjust timing? Have you got your own software? Or is it done s different way? Excuse my ignorance on the matter.

nitrous and meth works fantastic together and is safer than just nitrous alone since the meth raises the octane significantly to reduce the chance of detonation.

Photo,
Where are you injecting the meth? I don't remember seeing any pics or mention of where you installed your AIS system nozzle(s). That is going to be my next mod for sure.
If you don't mind sharing I would appreciate it. Also, you did get a tune specific to the meth use, correct?

Cheers,
KrzyFast

it should be all posted in my photo thread, yes i datalogged my car with a wideband for several weeks and had the tune customized for the meth/nitrous. My a/f with the meth and nitrous is 11.75:1 and my air temps in 90 degree weather with high humidity is in the 99 to 108 degree range. i posted a video on youtube of my AIT's. i also run 1 step colder copper plugs for safety. i posted up quite a bit of info with dyno's, datalogs of my a/f ratio and air intake temps and the meth mix all over the site quite a while back.

meth kits are super simple to hook up. i picked up about 25whp with my old car with just meth but it had a roots style supercharger so it had more of a heat issue than this car does. my air intake temps even stay cool on the road course with the meth, when i run on the road course i just use a 25% meth/75% water usually. that way it just cools the car and only increases the a/f ratio about .5

Photo,

I really appreciate you sharing! Thank you. I will have to look at those threads again. I must have skimmed over some of the info before.

Again, thanks!

Cheers,

here is a vid of the car's iat's after multiple wide open throttle runs. when the meth kicks on the temps stay in the 90's and when i slow back down and the meth kicks off the temps go back up to the lower 100's and then go right back down again when i go wide open throttle again. i did that like 6 or 7 times in this vid and the car never gets hot.

Yooooo man!! I figured I stop in and say hi. I finally ran my car with the meth setup (2 nozzels in the intakes and 1 through the supercharger) a while back and it yielded zero gains. Now granted my car is not tuned for it, but I thought it would show me something? Yeah, I ran exact same times with and without the meth. I want to eventually get it tuned for the meth, but I lost interest in modding the car and dealing with fueling and tuning issues.

how have you been! I haven't been on here for quite a while either. Do you still have your car?

We have tons of snow here, i have winter tires on mine but it hasn't moved for about a month due to the amount of snow we have.

I always try to use the least amount possible because it really increases your a/f ratio. I just use a 3gph nozzle and the least amount of alcohol as possible when i just use it for cooling (like at the road course). alcohol kits really are not power adders they just cool the temps and raise octane so you can run more timing. if you spray a small amount through the supercharger though you do pick up a little boost i see an increase of .5psi to barely 1psi depending on the nozzle.

Here is my dyno with and without meth before i datalogged and tuned back in 2009. I picked up a few whp from the increased boost from the meth.

I like the road course so much better that I haven't been back to the dragstrip since I added all the last mods. I sold my drag radials and bought some nice pole position tires for the road course.

Since the middle of the summer though i have fell back in love with bikes and been obsessing over that since then lol.

Nice! And as always your photo's rock! We are getting snow too, but I know it's not nearly as much as you guys! I still have my baby although I hardly drive it anymore......I probably put 2500 miles on it this past year. lol Yeah, I think im gonna leave it be and just enjoy the car for now......I am a little disappointed I couldn't get the car consistantly in the 11's, but such is life.

Bringing this thread back from the dead. I bought my car forever ago of from me photoman. Been spraying meth through it for over 10!years. I’m now running a wet nitrous kit through it to and changed the meth system from a 3gph to a 6gph progressive supercharger is still fine. That’s a lot of meth through it over the years and no failures. I say spray meth with confidence. With my recent tune I pick up 22hp with the meth and this is with a nitrous tune that pulls timing.
