As some of you may have been aware, I am currently investigating the use of NOS on the Noggy Babe. Got it tied down to a supplier (who had already fitted one to an RS4) and started talking technical. Well you cant just bolt on 300bhp without asking some questions, can you??

Suffice to say I wasnt too chuffed with this reply (after I nearly shelled out £2500 in November last year based on assurances it was spot on!)

Andy,
just had xxxx call and checked his install and I thought I'd got the set up right until I checked your schematic. I'm amazed that his system works as well as it does as it's now obvious to me that we have not fitted the system the way I intended it to be. I thought the 'Y' piece fed into the engine NOT into the turbos.
I must have missed the pics that you sent with this e-mail as it's OBVIOUS where the injectors SHOULD go (as you've circled).
If the 2 inlets feed into a common plenum chamber, you may get away with a single injector and single set of solenoids, BUT at worst you'll need a single set of solenoids and 2 injectors.
If you are still interested please get back to me for a revised quote.
By the way do you have any contact details for xxxx as I now need to get his install reworked as it will perform much better when fitted correctly.
Regards
Nugget

I've changed all names apart from the last one which seems quite appropriate [img]images/graemlins/laugh.gif[/img]

So here's the question. Do I.....

a) go with the flow, anyone can make mistakes, here's my £2500 and would you like to bugger me as well while I'm here?
b) stick some C4 in my combustion chambers as it's gonna go that way anyway?
c) stick some C4 up his jacksie, as a "well you were going to do it to me" sort of gesture?
d) hit him with so many lefts he'll be begging for a right?
e) forget the whole thing coz it only works in Hollywood and get meself a Panerai instead?

Answers on a postcard please......poll anyone?

I'd certainly get a second opinion Andy.

There must be other companies with expreience of fitting NOS to turbo cars. I'd start with the Porsche owners club in Germany.

Seems theres a mis informed person trying to sell you somthing he dosent know anything about [img]images/graemlins/smirk.gif[/img]
Personally i would try and get some advice from the states, or buy the Panerai [img]images/graemlins/grin.gif[/img]

Looked into the Stateside offerings - Venom, NOS (Holly), Zex and Nitrous Express, and unfortunately none of them offer a "wet" system (mixes NOS and fuel in a misting effect for more efficient and controllable combustion) which we need for a biturbo, so choice is limited [img]images/graemlins/frown.gif[/img]

A dry system (NOS only) is suitable but only as direct port injection whereby an injector plate is positioned between the intake manifold and the cylinder head. Not a good idea for us as space and maintenance (never mind fitting [img]images/graemlins/shocked.gif[/img]) would be a nightmare.

Will keep investigating, and keep everyone posted as events unfold

had nos on my tt wouldnt even consider fitting it on rs4 had good info today that can get 650bhp from rs4 using standard bottom end using motec ignition, bigger turbo's

[img]images/graemlins/cool.gif[/img] [img]images/graemlins/cool.gif[/img] way to go [img]images/graemlins/grin.gif[/img]

Any idea on max boost and compression ratio Steve? And how much modification do you reckon to the top end?

Andiroo

dont know exact specs as yet will let you know as soon as i do.
