Hey Guys, got my Z on the rollers this week  
  
Only achieved 266bhp   and mines the 296 bhp GT4 uprev version  
  
Mod's HKS panel filter and Japspeed K2 exhaust. 
  
Now i know im never going to achieve the manufacturers figures but hoped i would at least get 280 at the fly. 
  
They did struggle to keep it steady on the rollers and had to have a couple of attempts at tightening the belts , How much of an effect does the tension of the belts affect the figures ? 
  
Car has 32k on the clock , have i a duffer ?! i didnt even make non rev up figures ! 
  
I notice from looking at other peoples graphs their runs were done in 4th gear , mine was done in 3rd does it make a difference what gear is selected ? 
  
Any comments ? , i'm really sulking now !
