i have noticed some figures for bolt-on cars are a bit high(happy dynos) ie tie-down techniques and intake temps that are more than ambient temps which all do play a massive part in the dyno result.Which i was told by my tuner in which he doesnt even use the intake temp probe at all and straps down the car in the correct manner which is set out in the shoot-out mode if any of these procedures are not correctly done the power figure will be higher than it really is.ie bolt-on cars 250rwkw yeah right run it down the 1/4 and see what mph you run ,with that sort of power should be running about 113-115mph not the usual 105-106mph(210rwkw).my car "only" made 265rwkw cam/tune etc so you tell me why would these so called bolt-on cars make 250rwkw.The straps on my car were backed off(1 click) and the power suddenly jumped to 279rwkw which looks good on paper but is not CORRECT AND TRUE.The dyno should only be used for tuning cars.Cheers hope i havent upset any-one but thats my opinion thats all thankyou
