letmeshowyou Posted January 31, 2006 Share Posted January 31, 2006 Had the car on a rolling road this morning following my exploits at the weekend. Spec as per my sig and she recorded 290rwhp at just over a bar. What do people think? About right? Adi. (Bring on an exhaust!!) Quote Link to comment Share on other sites More sharing options...
Alex Posted January 31, 2006 Share Posted January 31, 2006 Sounds good to me with the auto box. Those NGK's might be a bit cold though...I'd give the 7's a go next time. Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted January 31, 2006 Author Share Posted January 31, 2006 I did wonder that when I ordered them but figured it would be ok for when I was eventually running 1.2 Are they likely to give me any problems? Quote Link to comment Share on other sites More sharing options...

Only thing they can really harm is you emmissions and starting performance, when not tanking it. Quote Link to comment Share on other sites More sharing options...

(Bring on an exhaust!!) that seems fairly impressive, isnt that over 380bhp flywheel? pretty good with those mods i be thinkin Quote Link to comment Share on other sites More sharing options...
terribleturner Posted January 31, 2006 Share Posted January 31, 2006 Depends what they say the percentage lose is, but i recon about 357fwhp. Get rid of the other cat mate Quote Link to comment Share on other sites More sharing options...

Get rid of the other cat mate ahh right, when i had my rolling road (4wd) the sheet gave both flywheel and wheel horspower, did yours? 360bhp is still good considering only one cat removed Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted January 31, 2006 Author Share Posted January 31, 2006 Get rid of the other cat mate will do when the MOT is done 357fwhp would make 19% transmission loss? Is that about right for an auto? Quote Link to comment Share on other sites More sharing options...
terribleturner Posted January 31, 2006 Share Posted January 31, 2006 No you've fallen where i did once , you have to work it from the other way round. Surrey RR use 23% so 290 + 23% is 356.7, but if you take 23% off 356.7 you get 274 odd. Does that make sense?? Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted January 31, 2006 Author Share Posted January 31, 2006 I think you'll find.... that you've fallen the same way you did before Quote Link to comment Share on other sites More sharing options...
terribleturner Posted January 31, 2006 Share Posted January 31, 2006 Oh yeah It's all too confusing. So i take it back, 290 is about 380 Quote Link to comment Share on other sites More sharing options...
Conrad Posted January 31, 2006 Share Posted January 31, 2006 Ok, total thread hijack but I'm a little confused so need to ask. Sorry 'letmeshowyou'!! My car is totally standard but I'm fully decating in the next couple of weeks. I'm currently on 0.7 - 0.8 bar and hoping for around 1.0 - 1.2 bar when the decat is done. What kind of approx figures do you think I'm running now and what kind of approx figures will l be running afterwards? I'm auto Jspec btw and it's a '94.... It's the rwhp and fwhp that's confusing me? which is which and what figure do people normally quote when quoting bhp? Quote Link to comment Share on other sites More sharing options...
TLicense Posted January 31, 2006 Share Posted January 31, 2006 The larger number, for pub bragging rights. (You wouldn't tell everyone you had a 2inch cock when flacid, if it's 12inches hard would ya!) Quote Link to comment Share on other sites More sharing options...
letmeshowyou Posted January 31, 2006 Author Share Posted January 31, 2006 fwhp = the power the engine is putting out. Only true way to measure this is on an engine dyno. rwhp = power at the rear wheels (with transmission losses etc taken into account) There's so much contention on % power losses it's usually safest to quote wheel or hub figures. Bear in mind auto's suffer more loss than manual ones. What's yours? Quote Link to comment Share on other sites More sharing options...
