As Lee said my car was VERY budget orientated lol

All I had was one of these



With an Escos Lamda sensor, No Widebands im affraid

BUT enough to show gross swings in AFR

Steve
thanks steve,very interesting .hopefully i will not need more than a 40 shot of nos.
All a long time ago for me now lol, any help I CAN give I will, but obviously Chip your man on here
OR
go here

http://www.technical-forum.com/nitrous-advice-forum/

to Wizard of Nos FORUMS, very friendly informative lot, well used to be lol, plus you get answers from the man himself Trevor, the Father of Nitrous in the UK (teaches the Yanks a thing or two as well lol)

Dont know what you using your Nitrous for but cant see the harm in a bit more (well unless you using it as an anti lag system ), like I say now days with smooth delivery controllers, dont have to put massive shocks on the car
Dont break things every launch if your extra power comes in steadily

Lloyd, I'm very suprised your seeing such a pressure drop with such jetting.

We run 150hp gains and see 250 psi drop over the 1/4, thats with a heater set to 1000psi.

A mate of mine runs a Corvette with over 300hp jetting, he has seen around 400psi drop which was cured by just fitting another bottle.

2 Bottles with high flow valves, 2 heaters and -4 hose is the complete setup running 4 solenoids.

Nitrogen Push "shouldn't" be needed with your setup imo.

What do you think Chip ?

So with no pressure - eg rwd is a skyline conversion in drag terms somewhere between a RWD cossie and a 4wd one as it has to still turn the gubbings in the front diff with the front wheels even if the centre prop is not driving it?
yes mate that is what the tests have proven so far. santa pod next weekend will put the figures into mph at the 1/4.ie full 50/50 runs .full rwd runs, then full 50/50 fading to rwd when ive got traction.

Lloyd, How did you get on @ the pod last Sunday?
