silvershark44 Posted December 10, 2006 Share Posted December 10, 2006 BPU with double decat on a standard exhaust? Given that stock see's me currently at 300bhp exactly mainly because im currently overfueling like mad as supras tend to do. Quote Link to comment Share on other sites More sharing options...

jamesmark Posted December 10, 2006 Share Posted December 10, 2006 Go for a good cat back on double decat you should get 30 bhp increase,but remember and replace smic, get a fcd and sparks Quote Link to comment Share on other sites More sharing options...
silvershark44 Posted December 10, 2006 Author Share Posted December 10, 2006 Yeah the rest is sorted, I just dont have an exhaust, just wondered if I would get a small BHP increase, about 20-30, but ill just wait till I choose a decent exhaust system.

If you go double decat and raise the boost to 1.2bar you should have some nice gains. A replacement less restrictive exhaust would allow for faster spool and cooler running due to less back pressure.

Darren Posted December 10, 2006 Share Posted December 10, 2006 And the car spools faster with no cats so you should notice the difference.. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted December 10, 2006 Share Posted December 10, 2006 Well I got 323 bhp with the stock system still on with no de-cat, so you can do better than that I'm sure Quote Link to comment Share on other sites More sharing options...
Jake Posted December 11, 2006 Share Posted December 11, 2006 Well I got 323 bhp with the stock system still on with no de-cat, so you can do better than that I'm sure At the wheels or guessed at? Quote Link to comment Share on other sites More sharing options...
Gazboy Posted December 11, 2006 Share Posted December 11, 2006 As stock I got 250 at the wheels, decatted but stock exhaust I got 275 at the wheels. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted December 11, 2006 Share Posted December 11, 2006 At the wheels or guessed at? 265 at the wheels with the 18% loss = 323 figure @ fly with 1% +/- at G-Force.. so pretty much spot on. Quote Link to comment Share on other sites More sharing options...
