Last week a customer contacted me expressing an interest in carrying out an RS2 Manifold conversion on his 182 to complement the 202 bhp he already had. I found it intriguing that at no point with a £1600 package had he been provided with any sort of graph demonstrating the cars raised output.
Last week he came over to us and we took the car to a local RR that we implement for all of our development work so I could attain a bench mark / gather data from the car before we can began work on it.
I had already prepared the unfortunate chap for the eventuality that his car would not make 202 bhp with the work the package includes (reground cams, live remap, exhaust & a sports filter). I was however still expecting 190 ish at a push (as per mild cams *usual* results)
Anyway:
(the blank space in the info boxes are simply where I have removed the numbeplate info used for the file names.)
Most worryingly the chap had added matched inlets after the 202 conversion had been completed, so I expect the true figure the car left MG with would have been even lower!
The graph appeared strangely similar to a stock car (albeit lightly tuned), so we pulled up a graph from our database of our own 182 (blue lines) around a year ago for comparison:
The car has none of the characteristic changes in torque delivery I would expect from a different cam profile. I wonder if anything has actually be done internally? The only thing that stops me from comitting to this train of thought 100% is that the car has the characteristic 'tappiness' of a reground cam.
Anyway I have posted this up as it frustrates me more than anything. With this sort of tuning going on no wonder people refer to tuning cars a being a 'mugs game', it not only screws over an individual, it also damages the faith people carry in the industry. :dapprove:
