BEE Racing BR REV LIMITER

[vboyq]

well there u go i guess i get it now. BTW wat about the group buy, i don't have my sr20det yet but i would like to know just for my own research purposes

[Siddhartha]

I think Paul was joking about the group buy, rofl . . .

[vboyq]

well forget i said nething then

[hokiruu]

BTW guys, AutoImaging has also carried this item for about a year

i think u need to have a test pipe installed in order to get teh flame effect...if u have a cat i think all u will hear is a loud bang or pop..correct me if im wrong...and count me in on the buy

[pampadori]

i have a testpipe, and the bee r revlimiter...i don't get any flames. i get some misfire and a occasional backfire. you have to get lucky to get a fireball out of it. also, its not really accurate...ie. if i set it to 4000, it goes to 4500rpm, sometimes 3800....but on the good side of things, i can build 10psi of boost in nuetral with it set to 6000 rpm. then i launch under boost.shaun

While searching some posts I saw no one ever answered one question in here. How does a real misfiring system work. As far as I know something like a sparkplug is welded into the turbo manifold and since there is still some fuel present it ignites it and cause combustion in the exhaust manifold making the turbo turbine spin up alot faster.

I think that is the only benefit to misfiring, as it has lots of downsides. Can blow apart/crack/explode your manifold, damage your turbo, and I don't see how **** loads of backpressure into the exhaust ports can be good.

Also THe only way you are going otbe able to shoot flames is a straight pipe. with a Cat It will should like popcorn. heh

Please flame me if I am incorrect about the misfiring:)

The product works by cutting the ignition spark where you want it to, say 5000RPM's. Then the fuel is still dumped in as it would normally be at 5000RPM's. It is not combusted in the chamber because of the lack of spark. This is why its considered a safe system, because it "is a safer way in the long run when the engine is over revved past its recommended RPM limits." (http://www.takakaira.com/asp/t...okrNm)

The fuel will combust either in the turbo to keep the wheel spooling (depending on the position of the wastegate, I have no idea what the wastegate will be doing) or it will combust once it reaches oxygen and provide a flame (assuming you have no cat to burn the fuel there).

It has the upside of better boost, and is supposedly safer because it avoids the fuel cutoff. The downside is that it can put stress on the turbo and catalytic converter.

there won't be any stress on the cat if u don't have a straight pipe.

I had this setup on my turbo civic, I had a hondata 3b unit that was far more advanced than this thing. It based the rpm/spark cut and diffrent rpms based on clutch and speed. Like thishad one setting for when the clutch was depresed and the car was not moving, that way you can launch at what ever rpm you want just like a 2 step. (and yes it wounld shoot flames)had a setting for when the clutch was depresed and the car was moving, so you could set it at say 8grand and shift gears without ever letting go of the gas pedal, thus not closing the throttle plate, thus not loosing any boost, thus no spool time between gears. Then it also had a regular rpm setting for top rpmAs for the coments on honda just poping and not shooting flames, yes that is just ricers. But real racers have been using this kind of setup for years. Now i dunno if the nissans have a setup this the hondata, they may but for the money this unit looks just like an msd 6al with a variable setting that anyone can make. But it might work good for those who dont want the hastle of wiring an msd unit to say all the cois on a sr20det. just my .02cent

[teriyakibroccoli]

it refers to the powerfc as a piggyback?

[SpeedRacer1]

Thats because it and the FCon V are piggybacks. Just very sophisticated piggybacks as opposed to something like the ApexI S-AFC.

[teriyakibroccoli]

hmmm.... apexi claims it to be a stand alone. fubar.
