    Guesstimated power?

    I've got an au1 xr8 manual. The modifications are: pacemakers comp headers, 2x 100 cell cats into 2x 2-1/2 inch mandrel exhaust and a pod filter. I don't have time to get it dyno'd and won't for some time to come. Any guesstimations on the power it might be making with these add-ons?

    Cheers,

    They'd be around 140 at the crank with those mods, gains are hard earned with the early small port 5.0's

    185 at the engine results in approx 125kW's at the wheels. With those mods you will gain an increase of approx 15 -20 rear wheel kW's (140 to 145 rwkw) so the final engine output will be around the 200kW ish mark. If you get it professionally tuned you will optimize the extra flow achieved from your exhaust/air filter.

    Cheers,
    Dyno's are a tuning tool, nothing more, nothing less.
    3 different dyno's on the same day, can yield 3 vastly different results.
    A wise man once said "Horsepower sells the car, Torque wins the races"
    Do you wish to make maximum HP at max rpm? or maximum torque @ midrange rpm?
    What type of heads are you running?
