Hi, I got my nitrous kit and it was only the hardware to install a complete purge kit. A 10lb Bottle, 15' hose, one solenoid, a push button switch to purge it and a wirring relay with all apropriate wires and instructions. So I put all this in and it works great. But not a single boost of speed. Well I ordered all the rest of the pieces and some little extras to make it a awsome set up. I will post the rest of the install as soon as the rest of the pieces get here, should only be a few days. Thanks for looking.
Hey guys, I finished the set up a while back and have been buisy with school so here is the update. The set up was easy as hell to install, and its practicaly fool proof. I used a NOS (name brand) EFI set up. The EFI set up made by NOS is a simple set up that comes with all the parts and only takes about three to four hours to install. The nitrous hose goes from the bottle to a solinoid and then to a nitrous fuel presure regulater and next it goes to another solinoid and then the hose goes into the intake. This is where the nitrous is sprayed into the motor. Fuel needs to be added to make the nitrous effective. The way to add fuel is by cutting the vacum hose that is on the car's fuel presure regulator and instaling a "T" fitting that comes in the kit. After the "T" is in place you run a one foot piece of vacum hose from the nitrouse feul presure regulater to the new "T" fitting that is now in the middle of the car's feul presure regulator vacum hose. The jetting specs are available on HOLLY.com as well as all install instructions and very detailed diagrams. There are many safety features available that make a setup expensive but you can get a basic kit and add all the fancy stuff later. I'm pushing a 125 shot right now and she is amazing. I ran a 2009 M3 coupe last night, we ran two runs both rollling starts and I got spanked both times but he was asking if mine was a 540 and I replyed no It's a 525, then he asked if it was stick and the answer was no. I told him it had nitrous and headers and ram air he thaught it was cool it gave a great fight. I have although SPANKED every thing else I've linged up with, and with ease. I highly recomend the add on if you do research on it and follow the rules its fool proof. By the way I,ve blasted through four bottles so far, so that means I've sprayed it at least 40 times and there is no problems in fact I'm pretty sure the car runs even better due to the fact that the nitrous cleans the motor to spotless every time you use it. I know it was long but people hate nitrous for some reason so I just like to put it out there in a lump sum. Thanks guys hope you try it out on your machines and get the most out of them. It is amazing what a BMW will do on Nitrous. If you have any questions just ask and I'll do my best to answer.
