nitrous specialist??

[chriswilks]

right i thought id call on the old faithful here as the vauxhall forums are bloody awful and useless sometimes,after a bit of extra poke out of my astra and thinking of going down the n20 route,just wondering wether u guys on here could give me some pointers as to what sort of things to look out for???

ANY info will be a huge help

Devonutopia and DevonMikeyboy have NOS on theirs IIRC - I would go for a progressive system at any rate, smoother and more tunable that way I guess

thought about water/methenol injection instead?

If your running 200bhp from your car can you not just get a bigger turbo ?

If it's a N/A, then put a turbo to it. If it's already charged, then put even bigger turbo to it.

This is what "red top" astra engine (N/A, 150hp originally, C20XE 2,0L) did with 1,2bar. Only upgrades to the engine were H-beam rods, exhaust manifold with Holset HE221W and DTA engine management.

470Nm @4750rpm, 311kW (~420hp) @5600rpm.

With 1,7bar it broke drive shaft into two pieces.

Here's the car. BMW with Opel engine.

Here's the engine bay.

well tbh i was trying to skirt around the idea of a big turbo,due to the amount i would use the extra power,and general drivability....and cost, as theres still alot of development going on!!wish id bought a bloody vag tdi now!!

also once you have an n2o setup,it doesnt mean its vehicle specific to a degree so could be used elsewhere in the future??

how often do you use yours mate??

not really,i wouldnt know where to start??!! never considered that as i didnt know about it!!

NOS can be moved from vehicle to vehicle but would need to be adjusted to the engine, so you may need to change nozzles if they cannot be adjusted enough. Pretty sure you could re-use the bottle, wiring and controller at least though

Remember you can't inject extra diesel into the inlet tract the way you would with petrol. You would need to run somthing with a much higher octane rating like Propane for the aditional fuel (or up the injector opening times, but this will be an all the time or switchable map (not that I know much about the ashtray TDi ECU)).

Water or Water/Methanol inrection is also movable from car to car. The water works to both cool the incoming charge and act as an artificial compression booster (old trucks used to do this with diesel to boost power on steep hills though it was only suposed to be used when starting), methanol is more effective in cooling the charge and acts as an aditional clean burning fuel.
