Cars going on the dyno, what should I expect?

My 1992 UK spec twin turbo Z is going on a power run dyno on Saturday.

 

What power should I expect to get at A. the wheels, and B. the flywheel?

 

Its a standard car apart from a Mines ecu, decat powerflow exhaust, twin mushroom air filters, and an electonic boost controller running it at around 15psi

 

thanks guys, Dan

    330-380 i would of thought. Depends on how good the tubs and engine are. Is you oil nice and gold and the filters clean, good condition plugs and running on good fuel.

    Most of us on the NW RR day hit around 330 at the fly!Although i got mine re-done and i few others and 2nd time round we all got another 20bhp! Mine was 348 at the fly and cant remember at the wheels around 300 though! But i only ran 12.5psi as i like to be safe :D

    Prepare to be Surprised :)

    Are you running stock turbos and injectors and what boost pressure are you going up to on the rollers.?

    Right-o, so...we had a few 'issues' with the EBC so basically just did a proper run on stock boost (0.8bar/12psi) and the figures are:

     

    Fly: 403.9hp

    Wheels: 337.4hp

     

    Not bad methinks though I am very eager to see what the figs would be at about 24psi!

     

    I've attached the graphs as well (poo quality I'm afraid!). As you can see I'm leaning out a touch which Charlie suggested would be fixed by a new aftermarket ECU but I already have the same JD chip that SMW was running (and had no such probs) so need to revisit this.

    Also seem to still have a hesitation problem whereby the power drops off completely on acceleration and only comes back if the accel is released for a second or two. Though this was the MAF so replaced it and for a short while the problem went away, but seems to be back ;-(
