Own a 2004 1.8T GLI with APR ECU programming. Installed a single nozzle Labonte meth kit a year ago. Labonte has since gone out of business but the kit is almost identical to what Snow Performance is offering. A DO7 Nozzle (7GPH) was recommended and was installed about 6" from the TB. I found the nozzle to be WAYYYY too large and it bogged down my engine. Damn felt like I could have hydro locked it. The shop I purchased the kit from insisted that this was the correct nozzle but tossed me a smaller size (size unknown) after my second visit to complain. This nozzle seems to be working well and I have been running 100 program on 93 gass or 93 program on 87 octane gas. After a friend of mine running the D07 nozzle on a similar setup had to replace his TB I decided that I needed to get a handle on my meth setup.
Scott from USRT has posted some really helpful information here on the vortex regarding Meth injection. We corresponded on the vortex and hammered out a plan to address my meth needs. I even had the pleasure of talking to him directly and was not only impressed with his Meth knowledge but it was clear this guy is passionate about cars! Weeks later I placed my order and very soon there after Scott called me to inform me that there might be a delay in the order because they did not have spare hose but quickly located a another kit they could "borrow" from to get my order out quick. Sweet ... not delays. I was later contacted by Justin (I think) who noticed that I had ordered an extra nozzle holder ant that I should be refunded the $18 it costed. Impressed! He didn't have to do that.
I am looking forward to receiving my parts and installing a two nozzle Meth setup. I will post back to tell you all how it went.
The motivation behind this message is really to tip my hat to the boys (and possibly some girls) at USRT. If you are considering this upgrade do yourself a favor and contact them!
I would put this upgrade on par with getting my car chipped and for those who are budget minded ... it can also pay for itself in one winter!!! Who needs 100oct program in slush anyway?
