Supradk84 Posted July 6, 2007 Share Posted July 6, 2007 Well, I am having at debate with some people over here about the jspec's bhp. They keep telling me it only has 280bhp. But I recall a coulpe of times, someone on here said that they easy could have 300+, if the ic ect. is in good condition. Can anyone confirm this. Mabey somekind off proof, I can smack in their thanks guys Quote Link to comment Share on other sites More sharing options...
grahamc Posted July 6, 2007 Share Posted July 6, 2007 280 bhp was the gentlemans rule/law for cars coming out of japan. No car was supposed to be over that number, hence why cars like the supra, 22b, gtr, etc all have 280bhp. But most of them have more.....

Whitesupraboy2 Posted July 6, 2007 Share Posted July 6, 2007 In Japan they has a gentlemens agreement of 280BHP so that is the released figure. However quite a few when dyno'd hit the 300 mark. Quote Link to comment Share on other sites More sharing options...
cheekymonkey Posted July 6, 2007 Share Posted July 6, 2007 They are "officially" 280bhp because japanese manufactures have agreed to only go as high as that. But they roll off the production line running 326 if I remember correctly. Course a 10 year old car will be running slightly less but it's still round the 300 mark!

Bobbeh Posted July 6, 2007 Share Posted July 6, 2007 That magic '326' figure is the UK spec number. As there is no propper figure its up for debate. Stock stock turbo'd JDM cars are over 300 bhp at least. Sadly there arnt enough stock JDM dynos floating around to get a decent picture of what they really do put out.

Class One Posted July 6, 2007 Share Posted July 6, 2007 When mine was stock (apart from a shite foam panel filter in the stanndard airbox) it was 262bhp at the wheels in an auto on Surrey RR. Take out the transmission losses and put it up around 300bhp ish for what was then a 13yr old car. Quote Link to comment Share on other sites More sharing options...

Ewen Posted July 6, 2007 Share Posted July 6, 2007 Lets not forget the mythical extra 25 bhp the TT VVTi alledgedly packs. Quote Link to comment Share on other sites More sharing options...
Suprasteve Posted July 6, 2007 Share Posted July 6, 2007 When i bought mine over 5 years ago i had my 94 6sp jap RR at Engine Advantages when standard came out 323bhp. Apparently their machine calulates the correct losses !? - who knows what the correct losses are... Quote Link to comment Share on other sites More sharing options...
Suprasteve Posted July 6, 2007 Share Posted July 6, 2007 Lets not forget the mythical extra 25 bhp the TT VVTi alledgedly packs. yeah but don't forget to minus 5 bhp for the red ones :innocent: Quote Link to comment Share on other sites More sharing options...
Class One Posted July 6, 2007 Share Posted July 6, 2007 Is that the run where you forgot to turn off the aircon as featured in J-Tuner? That wasn't me that wash Dash Rendar. He was bpu at the time and I made 20 odd horses more. Gutted was an understament on his part. Quote Link to comment Share on other sites More sharing options...
Darren Posted July 7, 2007 Share Posted July 7, 2007 Lets not forget the mythical extra 25 bhp the TT VVTi alledgedly packs. At the only group rolling road day I attended the VVTIs were putting out higher figures than simular spec'd Jspec cars. I think a basic decated one made 400bhp which no other Jspec with just a decat could get near.. Quote Link to comment Share on other sites More sharing options...
Bobbeh Posted July 7, 2007 Share Posted July 7, 2007 Hes talking about stock cars.. I remember you at the rolling road down at G-Force in Aylesbury and your car was one of the better BPU performers, anything modified fudges the figures.

I remember you at the rolling road down at G-Force in Aylesbury and your car was one of the better BPU performers, anything modified fudges the figures. I was just using it as a proven illustration that the VVTIs do have more grunt than Jspec. If they are more powerful at BPU they are likely to be more powerful standard. Well that was my theory. My car still had a CAT in on that day. Quote Link to comment Share on other sites More sharing options...
