Why my BHP gone...??

The torque figure is not necessarily a load of rubbish.
Torque at the wheels depends on what gear you are in.
Power is effectively torque x rpm. Say you have an engine that produces 100lb/ft torque and you stick a gearbox on the back of it that gives 1 revolution at the wheels for every 2 revolutions of the engine. The torque at the wheels is doubled, but the revolutions halved. This means that the power remains the same but the gearing changes the amount of torque you get at the wheels, and the rpm of the wheels.

Lower gears=more torque (and therefore more acceleration), but lower speed.
Higher gears=less torque (and therefore less acceleration), with higer speed.

If you're worried about the figure just ask them exactly what it is. You should be able to calculate flywheel torque from this figure if you know tyre diameter, gear ratio etc, but you may as well just derive the torque from the power.
 
i hope you didn't pay for that filter!!! it looks proper shite

are others starting to see the light now???? rolling roads are crap
 
the graphs you've posted are a bit weird

i remember when Eskiisbest's 172 went on K&N's RR his had somethig daft like 120bhp @ wheels

there rolling road needs recalibrating!!!

Can't beat the ol' panel filter eh?!

More like a cone filter to me in a special home with a bit of cold air feed to make it look nice.

Ill see what RR's are around here for tomorrow that aint too expensive....whats a good price for 2 runs, one with filter, one with airbox.?
 
Got a camera tho dont think it can record sound. Its definately louder than standard up too about 4.5k rpm then it goes quiet..

Im up in Peterlee (Nr Sunderland / Hartlepool) if anyone wants to come see it. May take it off later as we dont like it. Sounds a bit OTT for what we use the car for.
 
Some pics of the kit, as you can see ive removed it from the car. All is there to put the kit onto a Clio 182 / 172.

Cant put the item in the forsale section as im only a forum user.

I went to a scooby RR day recently and I had a similar thing happen with my readout....I don`t know the in`s and outs but apparently they uses the pulses of the battery (!?) to get the torque figures. The couldn`t do it so they read off the plug leads but they were too close together so it picked up two sets of pulses. This doubled my torque reading (321lb/ft) I have no idea how this works but everyone else got around the right reading so it must work. Everyone was buzzing about it at 1st as it would obviously be pretty quick with that torque lol
