Nitrous

Has anyone here tried n2o injection for there H3 yet. Im starting to collect parts and will be fitting it in a few weeks. FYI, Im Basically using WON pulsoids and injector, with FOJ progressing controller. looking for 75hp or so progressive power. It should be fun

If no one can help you here you can try coloradofans.com.

I would not do it unless you're running base size tires.

The engine really stresses to turn the additional rotational mass of larger tires, especially 35's.

If you start spraying on top of a situation like that, the cylinder temperatures are going to be very high.

It's common knowledge that you generally shouldn't spray in 1st gear, especially low RPM's, because the engine cannot freely accelerate.

The same principle applies here.

Thanks for the info. The tires are 33", and the FJO controller I will be using can sense if 1st gear... but my car is an automatic, so Im not sure if I can do anything about it. Never the less, as I will be using a progressive controller, I can introduce the power relatively slowly. I was going for 75hp max and may settle for less.

not knocking the idea, but why are nosing a hummer? Just curious. If you do, you have to share video though.

The alternatives to increase HP are very expensive. The setup should be very cool. I'm working on a way to 'fool' the pcm into retarding the timing during nitrous burns, so it 'should' be safe.

buy a replacement cylinder head/gaskets now, they go on backorder from time to time.
