I learnt that the hard way.I agree with you mate,I have used most tuners and Bruce and your good mate Street Tuner seem to get a bit more than the others...prolly pushing them harder but I'm prepapared to take the risk,and have been to dyno days without being embarresed.For those of us that have been here a while I find your preachings amusing after your claims when the wog tuned your car............BACKFLIP Link to comment Share on other sites More sharing options...

Bruce has been tuning race cars for a long time and started tuning the XR Turbos when they very first come out, he has a lot of experience, in no way am I gonna claim he is the best but you also cant say hes an amatuer. The number of cars that come out of HPT is very high and a lot have backed up the numbers on different dynos around adelaide, would be nice if we had a track here in adelaide to race on but we dont so for a lot of us the graph is all we have. For all you unbelievers may we see you soon at a track or dyno day near you. Link to comment Share on other sites More sharing options...

What boost??Mine was tuned on 98octane pump fuel with 18psi tapering down to 15 & raced the time/mph in my sig on the same fuel. Another example of dyno numbers not being a fair comparison is BCL's BF. It had similar numbers to ours on Tunehouses hub dyno yet ran 130mph. That would indicate that it in fact had quite a bit more power don't you agree? Link to comment Share on other sites More sharing options...

That would indicate that it in fact had quite a bit more power don't you agree?I'm not sure what you are referring to about a "fair comparison".A hub dyno will read higher than dd 6f, that's life. The dyno is used as a tool for tuning, the track for testing power.I've had 2 132mph runs (best 132.80) on 100 ron pump fuel and cat intact, and find I have about 2 mph variance amongst runs. That was with around 440 on the hub dyno. A slower runs seems to yield higher mph also.Personally, I think if a dd dyno is being used, my recommendation to all tuners is to stay with 6f for consistency, as that is what dd have established for 6 cylinder forced (hence 6f) injection cars.My experience also is that mainline dynos will also read higher than dd 6f, but not by as much.Up to around 350rwkw I don't think there is much difference between all 3.My view is that 6f is gets more conservative at higher power levels compared to the other dyno types and and always less than dd shoot8, 8f and 81 that use different ramp rates.dd shoot 6 is much closer to hub and mainline at a around 400rwkw than 6f.Also, fyi around 2001 when I used to have my STi dynod on a dd dyno, power suddenly increased around 15%. DD admitted their power calculations, which were derived, using a formula, had been wrong in previous years, and suddenly changed the formulae…. Now that was confusing! I don't want to start yet another argument; just my observations and each to his own. Better to just run the car at the track; easy test & BS stops there!Brian Link to comment Share on other sites More sharing options...
