Underworld Posted March 8, 2006 Share Posted March 8, 2006 I was just reading http://www.suprastore.com/supra/450hppackage.html and its saying that that BPU kit will kick out 430~460 rwhp. How come this figure is so high? Thought youd be looking at a conversion from 280->3xx on a jspec. Cheers Quote Link to comment Share on other sites More sharing options...
SteveR Posted March 8, 2006 Share Posted March 8, 2006 JSpecs are ~320bhp as stock Quote Link to comment Share on other sites More sharing options...
tbourner Posted March 8, 2006 Share Posted March 8, 2006 It includes a boost controller, so you could put it up to 1.3bar and probably get 450bhp - wouldn't fancy it on stock jap turbos though!! I'm on just over 1.1 bar and getting 400bhp. As Steve said, the 280bhp thing is a myth. Quote Link to comment Share on other sites More sharing options...
Underworld Posted March 8, 2006 Author Share Posted March 8, 2006 Oh right I thought it was 280 bhp Jspec and 326 ish uk spec. Thats really cool. Whats a rough average bhp for a bpu jspec supe? 360-400 bhp? So the real difference is the amount of boost you use. The extra boost would be ok on stronger turbos such as the uk spec i take it.

Alex Posted March 8, 2006 Share Posted March 8, 2006 1.) It's an American Site....US cars not j-specs 2.) It's US HP figures - read 10% more than anyone else 3.) SupraStore are full of shite - won't deliver goods etc Quote Link to comment Share on other sites More sharing options...

Nic Posted March 8, 2006 Share Posted March 8, 2006 As Alex says, the US hp unit is different to the hp unit used in the UK and other countries. There are actually around 4 different hp units in total I believe, not sure which ones the US uses, but their horses are obviously a bit weedy compared to our good old British Shire horses Quote Link to comment Share on other sites More sharing options...
Underworld Posted March 8, 2006 Author Share Posted March 8, 2006 lol. Why the hell do Americans have to have everything different...................................... Seems the same with everything. Any one care to elaborate on what an average ish RWHP figure for a Jspec BPU would be if transmission was in good nick and everything else was stock except for BPU components. I asked a while back but dont think i got a good answer From looking round on the seach seems to be like 320-350. Ta ;D Quote Link to comment Share on other sites More sharing options...
tbourner Posted March 8, 2006 Share Posted March 8, 2006 Yeah would imagine about 330RWHP. Quote Link to comment Share on other sites More sharing options...
