QSC Posted November 29, 2004 Share Posted November 29, 2004 I know this is probably a stupid question, but does the amount of RPM make a difference to what your BHP figure is when dynoed ? I thought a standard J-spec should produce 280 BHP with a UK at 320, but I just had my J-spec done with a result of 331 BHP at 6406 RPM. The guy said standard was 335 BHP, which the car would achieve if I used Optimax instead of crap fuel - don't quite understand as, as far as I'm aware, the car is completely standard ?

Jake Posted November 29, 2004 Share Posted November 29, 2004 Originally posted by QSC does the amount of RPM make a difference to what your BHP figure is when dynoed ? Yeah, course. The peak figure is still the figure quoted though. At what RPM that peak occurs will vary from car-to-car (and run-to-run) I thought a standard J-spec should produce 280 BHP with a UK at 320, but I just had my J-spec done with a result of 331 BHP at 6406 RPM. UK spec quoted as either 320bhp or 326bhp. The J-spec is unknown because the Jap car makers weren't allowed to claim over 280BHP. The usual figure seems to be anywhere between 300 and 320BHP afaict. The guy said standard was 335 BHP, which the car would achieve if I used Optimax instead of crap fuel You really should be using Super Unleaded fuel and preferably Optimax. Where did you have this dyno run? (Which company?) What was the BHP at the rear wheels? Quote Link to comment Share on other sites More sharing options...
QSC Posted November 29, 2004 Author Share Posted November 29, 2004 I had it done at Well Lane in Batley - they just gave me the one result, they didn't say it was at the rear wheels or what, just gave me the graph with 331 BHP on it - filled up with Optimax straight away & will keep it that way from now on - Quote Link to comment Share on other sites More sharing options...

Without Optimax you probably have around 310bhp and slightly more with it (and better running). 335bhp being the standard power figure is a load of arse. Cheers, Brian.

QSC Posted November 30, 2004 Author Share Posted November 30, 2004 Thanks for that, just a bit confused as to whether maybe something extra had been done to the car prior to me getting it, but I thought the garage would have said if it had - Cheers - Quote Link to comment Share on other sites More sharing options...
michael Posted November 30, 2004 Share Posted November 30, 2004 Well Lane are clueless with Supras, take the dyno reading as a rough estimate but it shows you are healthy at least As you are local will you be at the Showcase Cinema meet this Sunday?

QSC Posted December 1, 2004 Author Share Posted December 1, 2004 That's a bit worrying if you think they don't know what they're doing - do you know of anywhere else around here ? I've only had the car 6 months or so so haven't done anything with it yet - I don't know eyefi (from Ossett you say ? - thats where I'm from) but should be meeting up Sunday, as I've now been given the green light from She who Must be Obeyed, so see you there !

GeordieSteve Posted December 1, 2004 Share Posted December 1, 2004 I emailed Well Lane and told them what I was doing with the Supra and would it be possible to dyno there when I'm finished... they told me under no uncertain terms to bugger off! lol Quote Link to comment Share on other sites More sharing options...
QSC Posted December 1, 2004 Author Share Posted December 1, 2004 Why, what were you doing with the car ? Quote Link to comment Share on other sites More sharing options...
GeordieSteve Posted December 1, 2004 Share Posted December 1, 2004 Single turbo set up with emanage, 1000cc injectors etc. etc. etc. Quite a bit. Anyone know what Well Lanes rollers are rated up to? Quote Link to comment Share on other sites More sharing options...
