Best N55 Meth Kits?

I'm interested in installing meth on the car but the only kit that people seem to be using the the WW meth kit from BMS. Is this the only meth kit for the n55? For those who have installed meth, how are the gains? Do you recommend it? What kit are you using? Thanks for the help

All of the BMS meth kits work. I have the 2.2 Gallon trunk mount meth kit with stainless steel braided lines.

Works very well. I run a mix of E85/93 octane + Meth with Map 3. The most gains that I find are on a road course where over 30 mins of hard driving, you find very little heatsoak and power loss.

On the street it's pretty nice. Just more power. Not much to gain in terms of heat suppression if you run E85 + upgraded FMIC.

How much did you have to pay for your kit + install? Will I need to be filling up with e85 or is it just a personal choice? I do have the flex fuel wires already installed and currently am doing a 40/60 mix of E85/91 octane on map 5. I don't have an upgraded FMIC though so will that be a problem or is it fine? Thanks for all the help and have you put your car on the dyno? I'm curious as to what kind of gains the N55 see on meth and all the other goodies.

I have the bms meth kit with Devils Own meth nozzles, lines, solenoid, and the 2.2 gallon trunk tank.

Yes, because race car, you need upgraded FMIC. I have dozens of dynos which prove the benefit. U do NOT get large HP gains or TQ. What you DO get is LOWER IAT's, and in Florida....... anything I can do to make my setup run COLDER it's a good thing. The n55 has a bad heat soak issue, the upgraded fmic addresses this problem. Just do it.
