Mark@Abbey m/s Posted July 15, 2010 Share Posted July 15, 2010 I see lots of people asking whats does and what doesn't work on these cars. People think that you have to fit parts to get any gain form a Uprev this is wrong , these cars need to i,s dotting and T,s crossing even in stock form , if you cant afford anything other than the reflash just have this done you never be unhappy after a reflash. If you want to fit other parts see below; Abbey idea,s; all dyno proven on our Dynapack ( We have had our Dynapack for 8 years) DE 276bhp cars Best tuning mods; Stock airbox with a panel filter ( or find a REVUP 296bhp air box) again fitted with Panel filter these help a lot with inlet temp heat soak but do give the cars more torque than any Race type filter set up) and are quiet Remove stock cats , best De-cats are the Motordyne Resonated Decats but if you dont want to pay the money then stock Decats work , we try to use Berks as they seem the best quality (have used Japspeed these normally require some work to fit correctly) Y pipe we use Motordyne XYZ normally fitted with a Race cat , we find moving the cat away from the headers helps make the car produce torque/bhp and helps smooth the power out. You can always remove the race cats and fit a decat pipe/silencer to give a few more BHP. But running the race cat keeps the car 100% road legal. Motordyne 5/16 base spacer works as well. We reconmend keeping the stock exhaust system , good for 400bhp we have found nice and quiet for everyday use but with the above mods will bark when you floor the throttle. Revup cars; The same as above + we advise to fit a Motordyne Revup lower collector this together with the above mods gives these car the midrange torque that they are missing as a stock car. HR Motors; again same re the exhaust/cats idea as both DE and Rev up engined cars , these we find are best on stock airboxes people like fitting Nismo/Stillen filters kits for the noise but they dont give as much torque/bhp as the stock airbox set up fitted with panel filters. No plenum spacers on these cars thou ;-( hope this all helps I can do a package deal with regards the above mods if people so Quote Link to comment Share on other sites More sharing options...

narcotix Posted July 15, 2010 Share Posted July 15, 2010 Very informative post ... I've been considering the UPRev reflash for some time now but always thought that some engine modifcations were necessary in order to see any gains ...

I can do a package deal with regards the above mods if people so I'd be interested in XYZ with race cats & 5/16 spacer. In terms of package deals, what's the price for the above mods with a reflash?

captain Posted July 15, 2010 Share Posted July 15, 2010 Can you pm me a package price for the Uprev and fitting of Berks decats. Thanks. PS - I do track days with 100db limit. Currently at 88db with Blueflame cat-back exhaust. Any idea on increase in db with Berks decats? Quote Link to comment Share on other sites More sharing options...
alessandro Posted July 15, 2010 Share Posted July 15, 2010 Good write up, this will makes thinks clearer for many people ( including me ) Re filters, does an 06+ still better than an aftermarket with an air duck? ( hopefully I havne't wasted to muc money ) Quote Link to comment Share on other sites More sharing options...

busa1300 Posted July 15, 2010 Share Posted July 15, 2010 Hi Mark i've got a gt4 and you mention no plenum spacers for the HR Motors is that because you cant get them? i'am not sure what the gt4 engine is, the HR motor or the revup motor?

introspect Posted July 15, 2010 Share Posted July 15, 2010 Is there much difference between the Berk de-cats and the Motordyne resonated de-cats in terms of performance gains? Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted July 15, 2010 Author Share Posted July 15, 2010 Resonated De-cat pipes give more mid range torque. Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted July 16, 2010 Author Share Posted July 16, 2010 Lots of PM,s , working on prices at the moment , still waiting for stock Levels from Motordyne US, hopefully have some answer within 3/4 days. Mark Quote Link to comment Share on other sites More sharing options...
ceaser Posted July 16, 2010 Share Posted July 16, 2010 Folks I can confirm the effectiveness of this package on a DE non revup car the package listed by Abbey and including the resonated decats option has given me 263 WHP and 242 torques Quote Link to comment Share on other sites More sharing options...
