ok did the RR day with a local car club today , there were a few evo 6's a bmw m3 evo a N/A supra , couple of 200sx some one offs and a few others, the Z did us proud, a 17 year old classic car was the most powerfull and had the biggest increase over standard bhp as well( will put the plot up later)

 

375 bhp and 380lbft

 

That doesnt tell the real story though, its about the fitment of the underdrive pulley and the difference it made, the last RR at the same place was 369 bhp and 368lbft so the BHP increase was only 5( very warm day today though so with the same temps the operator would say 10 is likely) but the torque was a whopping 12lbft , not only this but the torque curve is now so aggresive its quite a bit above the bhp curve where as last time it matched the bhp curve.

 

Better still is the effect at the wheels ( the on the road power)

Last time it was 322, this time its 344 a whopping 22BHP getting put down on the road.

 

IF ANYONE ASKS IS A UNDERDRIVE PULLEY WORTH IT THE ANSWER IS YES WITHOUT A DOUBT.

 

In reality who cares though as i beat all the other cars there :dance:

Good man zeds RULE

Well done buddy, i have a full set of unorthodox pulleys fitted and it made a noticeable difference on my non turbo.
