Nitrous on a stock 08' busa

[gap4652]

Can I put a 40 horse dry shot on a bone stock 08 busa with no programmer without any problems. Thanks, DD

I wouldn't think so.. you have the speed restiction set on the bike. I would think you'd have to disable that first. The bike is already able to go faster then 186 mph but the fact its limited means to me that no matter what you put on the bike unless the restriction is by passed your going to go 186 mph and thats it..

could be wrong though..

I had a dry 40 shot on my 02, i had to richen the busa up top, i added 2 bars to the highs to compensate. Now on the 08, the compression is higher and im not sure how the GenII ECU works and this new A/F that the K8 seems to maintain under different factors and elements. I will tell you with NOS the main issue is reliability and not a question of "IF" but "When" ? NOS is the best bang for the buck IMO, however i would weigh it against blowing your motor:whistling:

I wouldn't do it without some sort of fuel enrichment. I use a PC with a custom map. I have heard bad things about just richening it with the adjustment bars but, I have seen alot of guys do it with no problems. If you are fogging the entire air box with one or two nozzles the temp sensor will richen it up some but you never know if its enough without a dyno tune.

The cheapest way out is to get a PC and a map for your pipe and atleast add fuel to that map. There is a chart on schnitzracing.com tech section to give you a ball park amount of fuel to add.

Hope that helps....

It would appear that you've assumed his purpose for NOS is to achieve high speeds when NOS is typically used to gain greater acceleration, in which case, speed restriction may not even enter the equation.

Fifthblade, NOS requires additional fuel, as it provides roughly double the amount of Oxygen. Even without adding extra fuel, you'll very likely feel a boost in power when spraying NOS, as the same volume of fuel will burn MUCH faster, but in so doing, it creates far greater HEAT (dangerously hotter).

When adding the appropriate amount of additional fuel, it slows the burn back down however, there is a much greater volume of expansive fuel to be burned, so greater HP is made possible at closer to normal combustion chamber temperatures.

You must add fuel when spraying NOS.

Now hear is a twist with the '08 having the o2 sensor have read how it will auto-adjust to a new exhaust if not another choice through schnitzracing.com is a Instant rich feature some use on the fast fi box.

The O2 sensor has nothing to do with wide open throttle (open loop). Its is just for drivability basicly street riding (closed loop). I've Talked to MPS about NOS. Air temp sensor will richen the fuel a little (small HP applications). But a PC is recommended (which eleminates O2S) for bigger 40HP dry systems. NOS is very reliable "IF" you have enough fuel to support it. But like the other guy said. DYNO it before you go button happy. :oh yeah:

The air temp sensor will NOT provide anywhere near enough fuel for use with NOS. I've extensively tested and tricked out the air temp sensor data to the ECM. Even when the ECM thinks the sensor has dropped down to 60 degrees below zero Fahrenheit, very little extra fuel is actually added (some yes, but comparatively little).

Best Advice: Do NOT rely upon the air temp sensor for the additional fuel required for NOS. Remapping a Power Commander map for use with NOS is the way to go. The MPS Fast FI tends to dump SO much additional fuel that the A/F ratio drops below 9:1 in the 7,750 through 9,250 RPM range, which kills HP big time and defeats the purpose of spraying NOS. Again, tweaking a Power Commander map is the way to go. :thumbs up:

how do you do that ummmm tweaking a Power Commander map for nos use :confused:

ADD +2 bars of fuel to the top end(highs) * I did that when i had a 40 shot dry kit

With NO programmer you can't use any nitrous.

With a PC3 you can but if you go 40shot (and that IS a big shot on a cycle) then i would not advise doing it at all without a map made for it on the spray.
