Can someone give me some useful contacts for NOS installation to minmise lag on a large Turbo Installation pls (the engine spec is extensive before anyone asks)

Someone mentioned Highpower in Doncaster on another post - but they dont exist according to 192!

Evade on the MRT forums has lots of experience with NOS on Subaru engines here are some threads.

Just to let you know I'll be getting NOS aswell.

And don't forget if you have a 400hp motor and you add 100hp of NOS your motor must be built to handle 500hp safely.

FYI a 10 pound bottle will last approx 100sec if set to give a 100hp shot.

For serious NOS you will also need to tweak the ignitoin for the NOS operation, as it's paramount to running more boost.

One way is to have a dedicated fuel tank for the NOS fuel supply (with it's own pump etc) and fill it with octane booster rich fuel.

Your normal ign map may be tame enough to prevent det, and there will be reduced temps that will help, but just bear it in mind.

Pavlo,
I only plan to use about 50 to 100hp and will investigate whether it can be mapped with a motec ecu and water injection. I was thinking along the lines of having it variable with boost so that when armed it comes in strong at say 75hp at 1500 to 2000 rpm then taper off as the boost rises. So with a 450hp external wastegate turbo with max boost arriving at 4000+ rpm. With nitrous this may be able to be reduced to say 2000rpm.

I think an external wastegate would be a must to have precice control of boost under these conditions.
I'm only speculating here but im going to see if it can be done.

Its going to be a long term project I won't be able to do it till next year.

Ok

I was not looking at a 100bhp yet

I only wanted 25bhp initially to get the Turbo spooling up quicker - plus its gimmicky - and yes you can drop down gears but I'm very lazy!

I was aware of the remote fuel source - I've read this - dont really know all the practicalities yet - and I also knew about the ignition advance

My engine SHOULD be able to handle 500bhp (wonder what the limits of the crank are!, gearbox, clutches!!!!) - I was looking for a bigger turbo than 450bhp - dont see the point of a remote WasteGate on that sort of power as the remote waste gates are not that cheap. Now if you were talking about say a large Garrett - pumping out circa 550bhp.....then would make more sense..

I must sort out the Cams! and the airfilter restrictions

I'm only aiming for a sensible 500bhp - we'll see

Am having a chat with some USA colleagues about the practical pro's and cons of Nitrous - but it sure aint cheap stuff!!

There must be loads of people that are using Nos in Aus???????

Progressive changes - thats what I'm looking at rather than simply an 'on/off' switch when you fully depress the acelerator
