Nitrous going on.

[rev210]

Hey guys got my nitrous kit yesterday.

Just wondering if anyone has any ideas about mounting the the throttle position switch.

I'll figure out a way eventually but, if someone has an easy way to position it that would be good. Saves me re-inventing the wheel.

[meggala]

interesting I hope you looking at upgrading your fuel system?

are you doing your turbo as well

hmmmmmmmm very interesting

wouldnt be my choice but thats why the world is such and interesting place

[rev210]

no turbo upgrade. No need.

The fuel pump I replaced the other day with a 600HP bosch unit, so it's all good.

[meggala]

50 shot or a35?

[WHITE R32]

mate just try this...... no ine ever said that the open throttle switch had to go on the throttle body...... they tried to tell us that too but we put it on the accelerator pedal under the dash way easy......and remember has to switch on at like 80-90% throttle not 100% like most ppl believe..... and a kind word of advice for ya..... dont ever jump on the gas while going slow or at low revs cause depending on how much gas etc u are running it will have a severe fit and a big backfire....... just my advice dude... your decision weather u use it or not as alot of ppl have varying ideas when it comes to nos.....cheers Jon

Rev - I'm dying to see how you go - should be great.

Depending on how technical you want to go you could put a mirco switch on the gearstick so the nos is only activated when out of first gear. And if you really want to go all out, you could use a comparitor and 555 curcuit so the nos only activates over ~3500rpm, or just modify a shift light

Of course you'd have a normal on/off switch to stop the nos from going on at all.

That would make it a little 'easier' to drive.

Oh, and we want pics pics pics

[rev210]

got a 50shot for now and a 100HP jet for later.

white r32,

here what you are saying bout the pedal idea.

[RNS11Z]

my mate just installed 50hp shot, he had 3inch tbo back zorst 12psi made it 286rwhp

[Merli]

Are you still aiming to get 12s without nitrous, stock turbo?

[rev210]

Yep, the 12 will be without nitrous and stock turbo. As it stands my re-tune should have me on track for a 280rwhp instead of the 230rwhp odd at 4700rpm (9's afr). The extra power I have is plenty to push me over the line for a 12.9 ,even with the razor blade 205's.

The 50 shot , and I'm afraid wider tyres, should put me into low 12's, the 100 shot into 11's.

[turbomad]

Hang on a minute REV your saying the stock turbo can make 280rwhp, I remember reading a post where you stated they could only make 300hp at the flywheel, please explain?

[rev210]

sorry,

That is relative to the particular dyno I went on. I'd say the stock turbo is still only 300 odd at the motor. The relative increase on that particular dyno to 280HP based on fixing afr and ping issue.

To put it another way: I'll have over 350HP at the engine.

[Guest INASNT]

a 100hp shot of nos will destroy a stock engine if not used right!

Are you planning on having the nos setup installed when driving on the street? and have u got a bottle warmer and purge system?

[rev210]

INASNT,

know my way around nitrous. The 100HP of nitrous is fine, just as fine as a 100HP increase with a hiflow turbo. As long as the engine internals can handle the extra power --- regardless of what provides it. The nitrous has the added benifit of correct mixture out of the box Vs new turbo that requires re-map and larger injectors etc.

As I said earlier the 50 shot is for starters, to get things sorted nicely.

The purge kit would be a good idea if I was racing and had a 250HP or so direct port. Keeps the lines 'liquified'. little power shots like mine don't need it.

Bottle warmers are good in cold weather, for the most part Perth is hot enough (except some parts of winter) to go without one.

Driving on the street with it?

No, I can't do that! Thats illegal in W.A.

[Guest INASNT]

rev

i mean will u have the system plugged (solenoids, lines, bottle) in on the street or only have it hooked up when u go to the drags.

Nos is illegal on the street on all over australia!

Also what are u gonna use to tune the nos?

[rev210]

INASNT,

the system will be in the car (lines solenoids etc...) except the bottle.

The EFI kit has a preset mixture, just change the jet. The engine tuning is basic... Retard the ignition, add a little extra fuel and shift gears 500rpm odd lower than normal (the torque increase is massive).

INASNT: What do you suggest to Matt to "use to tune the nos"??

a motec or autronic which has NOS inputs aux support to control exactly when you want the nos to come in!

[Merli]

That's not exactly "tuning" it, is it?

Yes, the neatest way is to use an auxillary output as a secondary arming switch, instead of a microswitch on the throttle body/accelerator pedal... Makes it much more stealthy

But as rev210 said, with a wet system, the fogger gives perfect fuel for the nitrous shot, so no extra "tuning" is required with a small 50-100 shot.

[rev210]

mallory I think make a nitrous rev controller. you just put in two 'pills' one lower rev range and one upper rev range and it arms the throttle pos switch based on the rpms being within the specified range.

Things like that are kind of like turbo timers, you don't need them but if your a member of AA they are helpfull.
