To NOS or not to NOS your 928

Hey Austin, we have all heard about those nasty nitrous gone wrong jobs.

I would not have considered it myself if I had not searched out more info on it.

When you search 928 nitrous on u-tube and watch the videos of the races and of guys running 1000 HP out of these little 5L engines it really started to make me wonder if a small 50 or 100 shot kit may not be to bad.

Now I really don't need the tickets and I know that more power will!!! be trouble, but ..... What the H3LL.

Who convinced me was (N2O-928) off of rennlist. I also asked him to add to this thread.
When he told me that it is more stable with the controllers monitoring the air/fuel mixture my ears perked up.

Both N2O-928 and Brett have convinced me to do it right, don't cheep out, and the rest is pleasure.

have you all seen this one?

I have been meaning to post the how to and lessions learned but have been working way too much OT to sit down in front of a keyboard, but i will do it.

Here is the kit I use, I also use their Progressive Controler, works great w/ our cars computer signals.
(you need to pull out at least 6 deg of timing I am doing 8 right now) and install two heat range colder non-projected copper plugs)

So here is my question.

How do i retard the timing on my 89 S4
I can't turn the distributor if there is not one to turn.
just 2 caps bolted to the cover

Brad,

The SharkTuner is your answer. If my understanding is correct, then the SharkTuner makes adjustments to ignition timing on its own. You give the SharkTuner information about what grade fuel, injector size, etc. and it programs ignition timing accordingly. Another advantage is the wideband o2 sensor.

Is the Shark tuner a scan tool? guess I could look which I will after this post.

Hi Brad

If you dont want to buy a Sharktuner, then John Speake will always blow you a chip with whatever advance or retard you wish....

He blew me one with the rev limit sort of removed for my 200 plus runs... he couldn't actually remove the limit, but he moved it up as high as he could ...which was 9710 revs lol, which I figured was just as good

I think he charged me £50 for the custom chip...

All the best Brett
