been toying with the idea of adding a 50-75hp jet kit to my scoob, is it worth it, how much power will i lose from retardation etc..?

on paper it sounds pretty appealing, insurance is a little nasty (£80 a year increase)

anyone care to shed any light on this funny gas?

oh as I have a VTA dump valve I will of course be opting for the purge kit too :)
 
Don't get a Wizzards of n0s kit.

Heard a lot of bad things about them.

How about getting a bigger turbo and just using the nitrous to spool it?

N2o injection dictated by a boost-triggered switch. Floor it and it injects the laughing gas, making the turbo spool quicker. Once it's at the required boost, the switch cuts the gas.

bigger turbo is coming when the xmas bonus hits the bank :)

im only going for a gt30/35, or a garret, so I dont think its large enough to have incurable lag (hope im not wrong), just been peering around the web and looking at *** kits and just struck me that once im around the 400hp mark any further gains arent that likely (or indeed wanted by me) without massive outlay, so to get a parttime 450 car I thought maybe *** was the way to go.
 
Would people stop saying N.O.S. That's Nitrous Oxide Systems, a US based retailer for it. The gas itself is N2O! :)

Holley (the N.O.S company :D)

Ok, I am sure I am being real dim here, but from what you are saying there it sounds like the N2O is injected directly into the turbo, to make it spin up quicker??

To me that sounds a bit wrong, injecting a highly combustible gas into a red hot chamber??

I am sure that I am wrong, it has been a long day (16 hours and counting), and I am not really with it at the moment, more coffee methinks.

Nope sorry - bad phrasing on my part :)

You inject it as normal. It increases the exhaust gases and allows the turbo to spool quicker :)

Okay no probs, but I am still being a bit dim, I admit I have not a huge amount of knowledge on N2O, but surely to use it at low RPM, as you are suggesting would over strain the crank and conrods etc.

I have never heard of a setup using N2O below about 3-3.5k rpm, usually they are fitted to only come in on full revs foot to the floor type scenario, so not a huge amount of extra strain on engine components.
Also surely using N2O at to low an RPM is going to overpressure the cylinders and cause detonation.
 
Well reccomended.

It's expensive to keep filling up the bottle, but the extra torque is mindblowing.

You'll be shoved into the back of the seat even at well over 100mph.

I've seen it a few times.

You don't use a big 50-75brake slug of gas.

http://www.google.co.uk/search?q=nitrous+spool+turbo&start=0&ie=utf-8&oe=utf-8 has a few links.

(A lot of crap too...but then again, it is the internet after all...)

Thats the point of using small jets, you map the car so it comes in before boost kicks in properly so the extra kick combats the lag
