Definitive De-Cat Opinion.126 is losing her warranty in May and I am thinking of having her De-Catted and Re-mapped (that will be it for her - no more mods)
As far as the de-cat in concerned, is it just the prodrive sports cat (just after the turbo) that is replaced with a straight through section? I don't want to remove any more than is necessary. I still want the prodrive exhaust, etc. - IF THIS IS THE CASE, CAN ANYONE RECOMMEND THE CORRECT PART TO PURCHASE? Have been trawling through all the de-cat posts on here and have seen people are achieving up to 347bhp with just de-cat and remap and no other mods. - DOES THIS SEEM FEASIBLE? Will this combination cause any loss of driveabilty? Have seen turbo surge mentioned a few times with decat & remap - IS THIS A POSSIBILITY? I would really like to have the power come in earlier - CAN THIS BE SORTED WITH A REMAP? Thinking of taking it to Andy Forrest for a re-map, he seems to be the guy... But he's almost 400 miles away... Clive Atthowe is near me and have heard he's good. - ANYONE HAD ANY WORK DONE BY HIM?
Re: Definitive De-Cat Opinion.
Good plan
I have just negotiated a 15% discount for all of my mapping customers with Japspeed off their range of exhausts. www.japspeed.co.uk It is just to decat downpipe that you need but you may want to change the whole system as the full 3inch stainless system is only £295 after discount and you would easily recoup that cost by selling your complete system.
Yes - had 365bhp out of a car that I mapped with similar spec before on the rollers... 350bhp is probably more realistic on average though.
Not if mapped properly.
yes
There are alternatives I charge £350 for a full custom remap. Duncan : www.racedynamix.com

Yes. Re MOT friendly - I know a few Am up in Norwich on thursday mapping - are you on scoobycity? Duncan : www.racedynamix.com

essentially too much air being sucked in (or trying to be sucked in) for the turbo to push out. Can be caused by induction kits and exhaust not being matched in the mapping. Some cars are prone to do it more than others and need tweaking of the boost profile to put them right. A lot of surge can destroy turbos but most often it is just a strange noise when occuring mildly. Duncan : www.racedynamix.com

Yes mostly but I have use of a dyno up in Norwich if you wanted yours mapped on the rollers. Would need to be checked on the road afterwards to get it 100%. It does add to the cost because of roller hire.... about £100 generally. Duncan : www.racedynamix.com

it could be me you are thinking about on scoobycity Duncan, i spoke to you about mapping my wr1 at the children in need convoy. is it really worth the agro come mot time to go the decat route for this level of tune, or is the standard prodrive cat really that restrictive?
Ah gotcha - that was fun that night The prodrive sports cat is very good - not a lot in it power wise - maybe 10bhp It isnt really a hassle when you know where to take it Duncan : www.racedynamix.com

your right it was a fun night! it was my first outing with the scoobycity bunch and i hope it wont be my last.. i have also been toying with the idea if new exhausts and i managed to pick up a blitz nur spec r for not a lot more than a packet of crisps, whats your views on this exhaust with an other wise standard car and would it be suitable if i wanted to go for further mods ????
Its loud
It flows well enough though - def suitable for future mods. Duncan : www.racedynamix.com

race dynamixI can vouch for duncan, he remapped my wr1 about 3 wks ago, he does it on the road, very knowledgabe guy, and my car feels and sounds so different now. ian
Cheers Ian

Duncan,
What do you expect can be achieved with a standard WR1 retaing the original prodrive cat and exhause?
Have you had yours on the dyno so far ?
A lot of std wr1's make slightly less power than the 320bhp specced. I would have thought around 330-340 would be along the right lines but better driveability mid range. Duncan : www.racedynamix.com

The air filter made a big difference
Clive's rollers are pretty accurate from what I have seen. Do you have the fueling/boost graphs too ? Duncan : www.racedynamix.com

The graphs look good - think there is a little more to be had - don't there is a vast amount though but that would be a guess without monitoring the car.

Think the WR1 is specced at 315bhp and 320ps
Do you think it's worth having it mapped then?
Prodrive state that peak bhp should be around the 5800rpm mark, it's nearer 6600rpm on mine.
Happy to hook the laptop up to it when I am up your way if you want to meet up and give you an honest idea of whether it could do better. It is very difficult to get a real feel for the car from dyno graphs made in artificial environment.

That's very kind Duncan.
Sounds good! When are you next up? I can't do this Thursday due to work and lack of 350 sheets - lol. I doubt you'll be coming either if the weather hits like they've forecast! I could let you have a look when you're next down and if you think anything can be achieved then I could bring it up to you for the real map...? Does it make a difference, say, by remapping it in the sub zero temperatures when ususally usually it's going to be used when it's warm?
I wouldn't charge you for just looking if I was up there ...
Hoping there will be a heat wave overnight ... bloody global warming needs to kick in soon
Am up in Norwich way every other week tbh and need to get up there again before the end of the month for an MOT ... will probs be the 26th
Not really although it does mean the turbo is more inclined to want to boost so keeping it in trim in this weather is harder. The performance in the summer is unlikely to be affected as a result whereas if mapped in the summer they can sometimes overboost mildly when really cold weather sets in. Duncan : www.racedynamix.com

What time will you be up here tomorrow? (from and until... I knock off at 16:30 and am 25 minutes from Central Norwich (Bacton) - weather permitting.
