My local garage who does all the work on my Z have just had a TATdyno rolling road fitted. :dance: Fortunatly for me they needed a car to test it with so was more than happy for them to use my Z as the test car!! :hyper: Had several runs done with & without the rollers having the retard added to them (alows boost to gain under engine load) My car is due to have the det sensor changed soon as the ECU is always giving a code 34.. Wiring to ECU fine etc..
First run my Z was making 320.4 BHP without the rollers having there retard on
Then with the retard on which gives the true BHP figure it was making 274.BHP with 243.2 lbft at 6736 RPM @ 165 MPH.. in 5TH Gear...
My Z is UK Spec & only has basic mods Blitz air filter, Z centre exaust system without CATS, E.G.R's removes, running standard boost with 360 thrust bearing Turbo's on 18" Wheels.. (Think one of the lambda sensors is Fooked too) :slap:
I thought these were resonable figures considdering I'm in safe mode (Was expecting a lot less). Would these be the sort of figures I should be expecting with this setup???
The engine was also connected up to the Rollers PC from the balance bar to measure boost pressure.. Boost was recored at 0.62 bar but internal aftermarket guages we're showing 0.4 bar (7PSI) (I'm totally puzzeld!!) :headvswal :headvswal :headvswal We checked the ECU after and it was still giving a code 34 so is the Z bleeding off pressure or is it something else in the system?? ) Internal aftermarket guages used to show 0.6 BAR before my engine swap so I know there OK!! Also the rev limiter was kicking in at 6736RPM - alway thought standard was 7200RPM...
