Is this product worth buying?

http://www.autoimaging.com/shop/images/11511.jpgUse the Bee Racing Rev Limiter to help protect your engine. Instead of causing fuel-cut which can cause stress on the engine, the Rev Limiter cuts the ignition. This action also results in a "mis-firing" simulation. If you have a test pipe on your vehicle, the results would be flames if you load the system enough with fuel. If you still retain your catalytic converters, you will hear a popping sound. The mis-firing control allows you to set the style of mis-firing simulation.

I am guessing that this might seriously reduce the life of a turbo (if any) and all associated exhaust plumbing.

wow.. i didn't think any product could top the "electronic sounding PSHHT"....


here's another product that can be put in karizma's full street/race civic

Aside from all the ghey "results would be flames if you load the system with enough fuel," rev limiters do have their place in a race setup. Pit lane has a very strict speed limit, and rev limiters allow the driver to not pay as much attention to his rpms while maintaining a specific speed. Result: Maximum allowed speed in Pit Lane, which could shave tenths of seconds or even seconds off of pit-time.

In addition, mis-firing (not providing spark to one or more cylinders) is the absolutely preferrable route to take to do this as opposed to cutting fuel supply to a cylinder. Misfiring a cylinder dumps a fuel-air mixture (which is low in temperature in comparison) into the exhaust manifold/header which passes to the atmosphere. However, causing fuel-cut generates a very lean condition in all four cylinders, causing a high-temperature exhaust charge which could melt pistons and turn them to goop.

Many of the ignition conrollers in the racing world do have a two-step rev limiter built in. An accessory to it is a remote button that, when pressed, limits revs to a user-set rpm. So whether on the drag strip (for launch) or pit lane (for the speed limit), misfiring one or more cylinders lets the engine run at a specific rpm without the driver having to do it manually. This is not detrimental to the turbo nor is it any more corrosive to the exhaust plumbing than regular exhaust gases.

yah, but a good msd ignition setup will have a built in rev limiter.

I heard spark cut means there is fuel being injected. When the fuel exits the cylinder without being burned, it blows up in the exhaust plumbing. Anyway, that's all hearsay and I have no experience with that. There are systems with fuel and spark cut though.

it's a big potentiometer.

From what i read and heard from friends i have to agree w/ ren's assesment that the system is too much wear and tear on your turbo and exhaust components. Vspec's 1st 1995 SR 240sx had a misfire system b4 and it went through most components pretty quick...it was later removed, also it produces a very bad and lumpy idle not mention attract unwanted attention and being destructive.
