VQ Engine after 24 bottles of nitrous

Cranberry

So its been a good year now and i feel this is a well deserved post. I should mention there are several other people on here that have done full nitrous install explinations etc... but there always seems to be those few people who condem nitrous with bold statements about “have fun blowing up your engine” etc...

First off I want to go over my set up to clear the air of any false senses of security that could arrise

- Nitrous system - Zex wet direct port with Wide Open Throttle Switch
- Zex bottle heater
- NOS window switch (on - 4100 rpm —- off 7200 rpm)
- NX Fule Safety Switch - (shuts down the nitrous if fule pressure drops)
- Autometer Pro Comp 2 Nitrous pressure gauge
- Autometer Pro Comp 2 A/F Wideband gauge
- HKS 2 steps colder plugs
- Wide band A/F readings at 12.2 on WOT when firing nitrous

I started running the nitrous back in august last year where i managed to get about 4 bottles through the car before putting it in storage for the winter. We got the 370 back out on the road in June and its been nothing but nitrous and fun since then.

Yesterday after burning our 24th 10lb bottle i decided to pull the throttle bodies and inspect the plugs for any detonation or over heat. The plugs had less then 3 km of regular driving on them when they were pulled. After review I can saftly say the engine is taking the nitrous with absoultly no issues at all!

Plugs on each bank






I am currently running a 75 shot but after the review of my plugs i feel its definnitly safe to up it to a 100.

There are a lot of people out there who condem nitrous, and i know its got a bad name from people over spraying more then the block or plugs can handle. But essentially from my experience and based on the condition of the plugs after heavy nitrous use. I believe as long as you stay within the HP ratings of your block and maintaine a 12.5 or richer A/F you cant go wrong.

Any way, i hope this can help calm some people on the “nitrous is bad” band wagon. This is my 3rd car im running nitrous on and will probably always choose the spray over the boost!
