Anyone used Sinspeed for a DPF removal
« on: January 16, 2017, 09:18:30 am »
As in the title, anyone used them or any recommendations for other companies in the south to remove the DPF and do the correct ecu re programme?

Thanks

With the D P F removed from the car, are you not risking a fail result at any future M.O.T .?

Officially has but they mask it up or find an MOT centre eager to turn a blind eye.

Yep !     Even if they mask it, should the MOT centre be aware that the car SHOULD have a DPF and find that it has been removed, it is an instant failure.

Often wondered if a car with the D.P.F removed and in effect,a dodgy M.O.T was involved in an insurance incident claim . Would the insurance honor the Cover or throw the claim out.??? :-\

Obviously it will depend upon the seriousness of the incident and what the projected all up cost of the event is likely to be.
 
Any Insurance company worth their reputation will check on such things. They go to far greater depths than the general public can imagine, to ensure that they are not being conned. 

If they suspect that the MOT center is, shall we say, less scrupulous, than it should be, then they, (the insurance company) will take every avenue they can to duck out of the claim. After all, lets face it, they are trying to keep hold of their money.

My thoughts are the same. Think the claim would be rejected and probable prosecutions follow. !!

So going back to the original question! has anyone had it done?

Yes I see your point on insurance and MOT etc however I am just trying to find out the differences in performance and reliability. Just curious

Performance will be better without the DPF if the manufacturer has not considered the impact of the DPF but the gain is tiny. Your concern should still be the law and the environment, in any order you prefer.

The DPF has more advantages than disadvantages, for example protecting the environment versus a tiny performance gain. If you overcome the perfomance vs environment argument, then you should think very carefully about the legal implications if the law enforcement practices change.

If you are performance focused and you worry about the DPF, you will become better and faster driver by attending advanced driving schools and upgrade the suspension, tyes and brakes.

For a segment D car, the DPF itself is a minor gain for the more of 1.5 tonnes you have to carry around. Also, I am not sure how much you can push to the limit such a big car.

If you are interested in straight line speed and acceleration, you could investigate remapping the car but again be aware of the legal implications.

https://www.researchgate.net/post/Diesel_Engine_How_does_the_DPF_effects_on_performance_of_engine

This guy mentions that the perfomance penalty is 1% for every 3-4kPa of added backpressure. He mentions that a DPF adds 0.5-0.8kPa of backpressure out of the typical 10kPa for the whole engine. Assuming that the manufacturer did not really care to find other ways to reduce this 0.5-0.8kPa impact of the DPF, then you will gain a 0.16-0.20% of raw power. For the 185PS diesel that is another 0.37PS raw power at most. Remapping the engine, upgrading suspension, tyres and brakes, and continuous training to become better driver, will make a more noticeable difference than the 0.37 difference in PS.

The reliability is not affected by the DPF. It is just a filter inside the exhaust. If you try to remove it in the wrong way, you will create a lot of problems but this is not related to the DPF itself.
