The NOS is amazing, I can feel the accelleration of the car under the turbo and just when I think that's fast, the nitrous kicks in and I can literally hear myself laughing out loud. I've been in a few Porsche turbo's and believe me when I say the NOS makes it faster. 40mph upwards is basically scaring me and I HAVE to hold on to the wheel as it pushes you backwards so hard it is difficult to describe in words. :driver:



I reckon you should be BANNED from this forum for your own good and that of all the forum membership  :grin: :grin: :grin:  Your description reminds me of the scenes in Fast and Furious when the 'NOS magic button' is pressed and everything becomes a blur  :evilgrin: :evilgrin: :evilgrin:  I'm having bad thoughts now  :laugh: :laugh:

Hi Hurdy ,
how does your AFR looks like with a 100hp shot ?
are you running stock or rs4 injectors ?

i would have jumped on this mod.
would be nice to run apr stage 4 + NOS
too bad NOS is an illegal metrial in israel.

Hi Poko,

I need to do a few logs this weekend with AFR and EGR blocks. I can't see much being wrong with the AFR as the correct ratio nozzles are being used and at the correct pressures. I'm sure there will be a proper Boyle's equation somewhere to calculate it out :laugh:

I'm running stock injectors as the NOS has a separate fuel feed to the ECU system.

I'm sure the UK will get around to banning it in a car at some point too  :sad1:

Where is this 'private driveway' you do all these runs on...?  :innocent:  Can I have a go...?

Sounds f00kin awesome so far, and I'd love to see the look on a supercar owner's face when the silver 5-dr Golf tears up the strip way faster than him...

Are you using a direct port setup hurdy? If not where about have you located the jet to get even distrubution,
Only reason i ask is i have a single jet progressive system.

Update...

Had to go a little further afield to a longer,flatter, straighter strip of tarmac to get a qtr mile time up. Only had 3 attempts, and the 2nd one was the best. Trevor phoned me and told me off about not using the nitrous in 1st gear and gave me a few setting ideas to use nitrous off the line instead of revving the engine and using the turbo - definitely worked and is more stable a run off the line.

Increments to 100mph.

next increments

This gave a best of...

Resulting in...
Golf R gone.
