We just finished up with this Nitrous and Methanol install this week. We have installed Methano on a few NA Cars now. It is a fuel source so it richens up the cars a good bit and needs to be retuned when using it NA. You have to be carefull with the mixtures though. Just like when running Torco, race gas has a slower burn which can cause a loss in power. We witnessed this with this car. The wrong jetting for the meth and this car was losing power. After getting the meth right the car was back where it needed to be. It didn't make any more power. What it did do was lower the intake temps by 30 degrees. This is nice for going to the track on hot days.
Now onto what the meth helped with tremendously. Usually when running a 100 shot you pick up 100 give or take a few ponies. I normally tune the cars down for spray. We hooked a Lingenfelter timing box to the setup so we would not change the NA tune. It is wired into the Nitrous Switch so when it is on the timing is automatically drawn back. With the timing back it dropped the car to 550 rwhp. When we sprayed the 100shot we picked up 190rwhp I can honestly say I have never seen this. From 550 to 740rwhp. We even backed the shot down to a 75 shot and still ran 681rwhp, +130hpgain.
Needless to say we were very impressed. I had planned on running 125shot on the car, but with the results and a stock bottom end we felt it was best to leave it at 681 for the trip home. If our customer decides to pump it then that up to him
The Meth being a fuel source give a nice margin or safety for nitrous as well, but like I posted earlier you need to know when enough is enough. You can see huge gains with out having to use a huge shot of nitrous. This is a very big plus. We have picked up power, usually 7-10 with meth, but it was 60 degrees in the shop today. The Iat's were dropping to 30. It wasn't 100 like it has been in the past few months. I hope you guys like to video and graphs.
