Sliver

Model: Nissan Skyline R34 GT Saloon [R34 RB25DE] Neo, Tiptronic Mods: Splitfires, 98RON fuel (UK) (Otherwise standard) Power: 136.2 BHP @ 6000 rpm | 101 rwkw @ 6000rpm (At the wheels) There is a bit of a glitch around the 5000 mark, does the variable cam come in at this point? Is there anything I can do with the fueling to smooth / lift the power curve? Also does anybody know how I can determine the peak torque from this graph?

Thanks! You have a nice car there and its generating some great figures, I am assuming the power is at the wheels (rather than at the fly?) Looks like I have a bit of modifying to consider before going down the N2O route. Not sure I need the injectors as the N2O manages its own fuel, did you have to modify the ECU to run the N2O, trying to determine if the stock ECU will be sufficient for my needs? I am coming off the back of a 300bhp 200SX which I modified myself, thought I would try something slightly different with a 4 door N/A, running N20

Fantastic, this is the first reference I have found of a N2O fitted to an N/A Skyline anywhere I am based over in the UK and have a N/A R34 GT 4door, that I am looking to add N2O to it. Everything on the car (other than Splitfire coils) is standard, so not sure what gains I am going to see. Could you post a scan of the dyno graph so I can get a better feeling for both the hp / fueling and torque that your acheiving. It is legal to run N2O on the roads in the UK as long as you have insurance that covers the modification. I have a couple of questions, if thats OK. - You mention and aftermarket ECU, could you highlight what this is, does it provide different fueling? - Do you have any other modifications that may affect the performance (exhaust, intake etc?) - The feed from between both intakes into the rocker covers, did you block this? It has a one way valve that draws air from the rocker cover on idle, I may reconfigure this as I am not really happy with N2O and fuel getting anywhere near the rocker covers. - Are you having any fueling issues? Did you fit a larger fuel pump? - Why did you only go for 55hp, rather than 75hp? - Do you have a 'progressive' controller on the N2O? - At what revs do you dring the N2O on, do you trigger manually, microswitch on the throttle, or a TPS? Is this set to 80% or more? - Are you running a manual or tiptronic box? Thats a lot of questions, sorry, but I have been hunting for information for a long time, and this is fantastic to find somebody who has already had great success. This will have a LOT (and I do mean a LOT) of torque over a turbo system, with zero lag and the option to 'switch it off' anytime you want to just bumble around town. Very nice setup! Would be fantastic to see what sort of times you have down the strip. Now I am going to wander over to the newbies section to introduce myself
