jbk Posted July 31, 2015 Share Posted July 31, 2015 Hi all I was wondering at what bhp figures I'd be looking at with just a remap on a standard wrx? I'd prefer to just spend the money on a handling package, tyres, 4-5 track days a year to be honest. Otherwise I've seen the choices available....for about 280 + bhp ..2000 pounds +!!! Of course a bit more oomph is always welcome especially in the mid range. Has anyone done just that and were the results satisfactory and most importantly trouble free in the long run?

stants Posted July 31, 2015 Share Posted July 31, 2015 High flow panel filter, exhaust & fuel pump will get you around the 270 mark from a td04 turbo, so roughly 45-50bhp increase, depends on what exhaust you go for price wise, but a grand is a ball park figure all in Quote Link to comment Share on other sites More sharing options...
Gambit Posted July 31, 2015 Share Posted July 31, 2015 Depending on filter might be able to get 250 260 on a standard wrx :) Which isn't to bad ;) Quote Link to comment Share on other sites More sharing options...
BoozyDave Posted July 31, 2015 Share Posted July 31, 2015 the 05 wrx can get between 260 - 280 bhp from a remap (mine only made 263bhp with remap and exhaust). Depending on supporting mods, some can get 290-300bhp, but not often. The main increase from a remap is midrange power and torque, the car is more drivable lowdown. the peak figure is just for bragging with. the midrange is what really matters :) Quote Link to comment Share on other sites More sharing options...

I still have all cats and a remap made 272. Massive difference to standard, just such a smooth power delivery [emoji106] Quote Link to comment Share on other sites More sharing options...
jbk Posted July 31, 2015 Author Share Posted July 31, 2015 Let me get this right...so If I keep all cats and exhaust standard and just do a remap the obtained figures are going to be around 250? maybe slightly more? Quote Link to comment Share on other sites More sharing options...
JusNoGood Posted July 31, 2015 Share Posted July 31, 2015 I'd suggest upgrading the backbox to a PPP or WR Sport, Only cost me £100 and fit a panel air filter £30. No point not doing those if you're paying £400+ for a remap. My mechanic suggested fuel pump just to be safe. And you're looking at 260-275 Quote Link to comment Share on other sites More sharing options...
jbk Posted August 1, 2015 Author Share Posted August 1, 2015 I've already replaced the filter (K&N)... Thanks for the info guys. Any links for a PPP backbox (or anything proven similar) to order online? Quote Link to comment Share on other sites More sharing options...
stants Posted August 1, 2015 Share Posted August 1, 2015 For those hp gains you'd need to looking at going full decat or a sports cat back system, plenty around used or if your flush new/custom build Quote Link to comment Share on other sites More sharing options...
JusNoGood Posted August 1, 2015 Share Posted August 1, 2015 Stants, for 265-270? I've not decatted. I have all the standard cats....including the one the full PPP exhaust system doesn't have. and I have the graph to prove 272bhp :D Duncan from Racedynamic (mapped mine). He said he tends to get more bhp out of the later model Blobs than the earlier blobs and bugs. Wasn't sure why but thats what he tends to see. I think it's quite incredible you can buy a 10 year old scoob and it has the same bhp as when it left the factory. Quote Link to comment Share on other sites More sharing options...
stants Posted August 1, 2015 Share Posted August 1, 2015 Yes I used dunc but ad you say he does get better results out of new age. Have you decided to keep yours then? Does the prodrive pack delete one cat and replaces the downpipe cat with a high flow cat ? Quote Link to comment Share on other sites More sharing options...

Does the prodrive pack delete one cat and replaces the downpipe cat with a high flow cat ? I decided to keep it until I move....and take a bit more equity out of the house to buy a better car than I can afford right now. So still got it mate :D I do really enjoy driving it still so not a hardship for me to keep it. Just been on a 3 week holiday and I'm like a little kid again...all excited to drive it I thought it just removed the downpipe but my memory isn't as good as it was :D 1 Quote Link to comment Share on other sites More sharing options...
JusNoGood Posted August 1, 2015 Share Posted August 1, 2015 After a bit more reading I think you are right Stants....downpipe replaced with high flow :) ... I have standard cat on mine 1 Quote Link to comment Share on other sites More sharing options...
ChrisD Posted August 3, 2015 Share Posted August 3, 2015 Mine was stock bar a high flow panel filter and a different back box, remapped to around 250, a decat down pipe and new fuel filter was my next step taking it to 260. I then went STI VF35 turbo, pink injectors, decat up pipe and got to 315 (but i think with a better mapper i may have made more) Quote Link to comment Share on other sites More sharing options...

JusNoGood Posted August 3, 2015 Share Posted August 3, 2015 03 :) blobeye Sent from my D6603 using Tapatalk Ah right. Yes, that fits with what Duncan was saying i.e. earlier Blobs don't make as much bhp as later. No idea why but interesting isn't it :) Quote Link to comment Share on other sites More sharing options...
Phila67 Posted August 14, 2015 Share Posted August 14, 2015 Lots of people mention k&n filter. But, I have also heard that they can damage you maf? Is that right.? Sent from my iPad using Tapatalk Quote Link to comment Share on other sites More sharing options...

Tidgy Posted August 14, 2015 Share Posted August 14, 2015 track work is very different to road, oil temps, fuel supply etc need to be thought about Quote Link to comment Share on other sites More sharing options...
ChrisD Posted August 15, 2015 Share Posted August 15, 2015 Yes you can damage maf with an oil covered filter, you can clean the maf to keep them going longer (vids online) or you can run maf less through a remap.
