Right then, I was just thinking lateraly.
Could I get a useful NOS shot for a 1/4 mile drag, from a scooter NOS system?
You know, the ones that use the 16g whipped cream canisters(like shown below).
I know I won't get much from 1, but would I get enough to make a difference on a drag run?
What i wondered was, how much NOS does, let's say, a 25bhp shot use?

Ironically, i was discussing this today.

Concensus was that (from previous knowledge) on a 2L car running decent sized jets, would use 1lb of nitrous per quarter mile - roughly.

I doubt the little sparklets would do much.

Mmmmmm, I just wondered if I could get a single shot, in 1 gear(maybe in 2nd or 3rd), as I ran the 1/4 mile.
It was a thought I was having for my BMW 328i, £999 Challenge entry. I just wondered if I could get a usable kick out of 1 of those £20 kits, I'll have to see if I've got enough time and money left for a 2nd hand kit off the bay...

How about 2 or more?

I collected my 10.5L six cylinder nitrous kit today. Do you want to borrow that?......






Yeah right!!!

I've always wondered how those silly Nitrous Oxide kits on eBay inject the extra fuel required? It appears they don't have any facility for this, so all you'd end up doing is dangerously weakening the mixture.

Then again with 16 grams in a sparklet it's all going to be over in a second or so.
