Re: Nitrous & Meth
Hey Kolevski,
I have a ZEX wet N2O kit purchased at Eurocharged during my tuning week at the their shop.
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
