Has anyone added a nitrous oxide system to there type-4 motor? Any thought on doing this?
In "Hot VW" they are doing this to a type-4 motor, but haven't finished yet. What are some considerations when adding a 50shot or 100shot. -Britain |

I was trying to buy a 914 that a guy had turboed and added NOS. He said the first time he rev'ed it out and hit the nos it blew the intake manifolds right off it. The 914 was only $600 because he didn't know how to fix it.
I thought with nos the heat was the problem, too hot a burn. Geoff |

NOS is cold (which is why you see them using bottle heaters to raise the pressure in the bottle)
Its the thermal shock associated with cooling a hot piston down that causes them to shatter. B |

I ran 100hp NOS fogger kit about 14 years ago on a 1776cc VW engine controlled by a Jacobs Nitrous Mastermind. It was great! No problems at all.

NOS really came on strong when injection became popular. The biggest fear is leaning a cylinder out while on the bottle. This was easy to do with a carburetor (lean a cylinder out and burn holes in the pistons).. injection gave us better fuel control.
Its a waste. Buy a turbo or supercharger. Finding a place to refrill NOS bottles in NorCal is not real easy... B |

you should be able to slow down the system .....hell i dont know.............but i do know i wouldnt. if your serious trade your 914 for a honda ......or let these guys tell you how to make your car perform with mods you will be happy with.

Well.. if you look at his avatar (912 Porsche)... we could Turbo his type4 engine or his 912 engine very easily. We could even use a stock 930 intercooler.

One big pisser with the NOS is that no one allows it for any type of road race or auto-x event.....the bottle alone will cause you to fail tech.
Personally, i think NOS is stupid on a street car, why put a device on your car that you cannot use anytime you feel like it? With NOS, the bottle has to be opened (and filled), sure they have remote systems, but what if you run low and cannot get to the filling station? I'd rather have a powerbooster that I know I can use 24/7 and with a degree of "real" adjustibility (the gas pedal being the main one) |

while in NOSLAND, what is the difference between a WET setup and a DRY setup?
also, NO2 raises the amount of oxygen in the cylinder right? then why not run staight up o2, its all around you and you just got to bottle it? anyone ever super-charged a teener or VEEDUB for that matter? |

The was a Florida company back in the early 90's who sold a supercharger kit for 2.0 914's. It looked "ok" except they used a HOKEY 2 barrel progressive Weber on top of the supercharger (and it made it into the magazines... how... I will never know.

A wet NOS system injects fuel as well as nos, and a dry only nos.. Nitrous is to cool the charge, and for extra bang (correct me if im wrong). What you could also do is a water/methonal injection system, my father has one on his car, but we didnt see much increase in hp, although he havent tuned it yet though... and the compression numbers are low on his car, and we need to put a new headgasket on, ext, but hey thats his track car..
