^ Is that too big a risk to chance?
I will run this past my indi when I take it for a check over in the next 2 weeks.
Did I mention I start 2 weeks holiday this Saturday?:bannana:
Thanks for your input David. I would guess my indy could tell if the engine is non standard just by driving it himself. I would imagine they get to drive plenty of 55k cars at MBS in Southampton.
Also, another E55 owner may well be able to tell.
If your Indie see's enough 55K's then the should be able to see the difference on any modifications made altenatively PCS in Horndean have more 55K powered cars at there workshop than most and are experienced to see the obvious changes.
Exhaust work is easy from inspection, most likely changes are either primary or secondary decat. Some also change the cats to sports cats but again easy to spot if they know what the are looking for. Check center box is still there a common one to remove for additional noise and reduced back pressure.
Headers is just as easy the stock one is a log style one.
Heat Exchanger and charge pump visual inspection will tell if they are upgraded.
Supercharger pulley, the majority of performance ones are made of alloy stock is steel. Stock diameter measured from the pulley belt v's is 90mm performance ones will be smaller typically 84mm.
Crank Pulley measure diameter in the same way as the supercharger pulley stock from memory is 155mm, performance ones come in 168, 172, 175, 180, 190 & 200. Most common are 168, 172 & 180.
The are lots of other possible mods but the above will cover 90+% of the modified cars in the UK.
Finally remap I have not found anyway to tell that a car has been remapped in STAR but thats not to say it cant be found. Driving them is also difficult to feel the difference many standard 55's can have small niggly issues that result in a huge variance in speed and feel. Poor circulation of coolant through the supercharger, boost leaks, plugs and leads the list goes on. Some are just prodcuing bigger numbers from the factory easily as much as 50hp (about the same you would expect from a remapped car) can be found from one stock car to another.
If you want to ensure your car is not running a remap you can always book the car into a MB dealer and have the ECU flashed with your original stock settings. I dont think its that expensive either I think I was quoted £50 by one dealer.
