Finally Dyno results regarding Herrod exhaust done
Yes boys and girls the results are in. the reason im doing this is because i fitted a set of herrod headers and the owner thought that it had lost power. the problem was that the torque droped in the low to mid range giving this effect so i offered to refund if there wasnt results.He was presant the whole time and was very happy to see what he did. The dyno was a dynamics dyno and was done in shootout mode.
The car was a GTP manual with std wheels and had done 6,500 km.
218.8 kw standard
221.3 Bmc air filter
227.8 headers + cats (torque dropped 10 nm)
239.6 unichip (also fixed throttle response)
246.1 cats back stainless system (fixed torque by 15nm but lower in range and more stable)
we have to retune the unichip now that the cats back system is on so there may be a gain again or there may not, but it atleast this gets rid of the bullshit about Mr Herrods system.
