Jake Posted July 26, 2007 Share Posted July 26, 2007 I knocked this up to compare three single turbo Supras that have all been Dyno'd at Marlin Motorsport. http://img510.imageshack.us/img510/8255/comparisonofsingleturboie8.png Quote Link to comment Share on other sites More sharing options...

wkdtime Posted July 26, 2007 Share Posted July 26, 2007 Jakes spools beautifully, defo the one I'd go for:) Suprafan2 will be wheel spinning its nut's off....low power, low power then bang big power. Quote Link to comment Share on other sites More sharing options...
suprafan72 Posted July 26, 2007 Share Posted July 26, 2007 Jakes spools beautifully, defo the one I'd go for:) Yeah i was thinking that... I do like Jakes Power curve. And you'd be surprised with my mods.. that i dont really spin that much.... Quote Link to comment Share on other sites More sharing options...
Jake Posted July 26, 2007 Author Share Posted July 26, 2007 Jakes spools beautifully, defo the one I'd go for ...but Andy's makes a shed load more power. Shame you can't have both, isn't it Quote Link to comment Share on other sites More sharing options...
JamieP Posted July 26, 2007 Share Posted July 26, 2007 Which might that be?? Jakes, when i went from the T88 to the GT4088 i lost about 100peak bhp, but the way the smaller turbo delivered its power made for a far faster street car, id never go large turbo again for a street car, Imo have the best of both worlds, small to mid size tubby with Nos for that extra top end punch if you come up against something real fast.

wkdtime Posted July 26, 2007 Share Posted July 26, 2007 ...but Andy's makes a shed load more power. Shame you can't have both, isn't it Jake, whats the use if you can't use that power and put it to the road on everyday road conditions. You'd probably leave most Grande powered singles round a track.

Alex Posted July 26, 2007 Share Posted July 26, 2007 Hey Jake any chance you could add in SimonB's T35R vs. T67DBB?? That would be most useful While you're making 300HP at 4000 rpm and really motoring the others would be losing so much time in a roll on.

Jake Posted July 26, 2007 Author Share Posted July 26, 2007 Hey Jake any chance you could add in SimonB's T35R vs. T67DBB?? Sure. I'll be guessing the numbers from the graph but it should be pretty close. You don't happen to have the data in text/Excel format do you? Those are RWHP, right?

Jake Posted July 26, 2007 Author Share Posted July 26, 2007 Hey Jake any chance you could add in SimonB's T35R vs. T67DBB?? That would be most useful I started doing this but soon realised that unless Ian and Simon's cars are making over 600RWHP and 550rwhp respectively these figures can't be right. If they're Flywheel figures the comparison is meaningless. Quote Link to comment Share on other sites More sharing options...
Nic Posted July 26, 2007 Share Posted July 26, 2007 Interesting Jake, I've attached a copy of my dyno of a GT3582R, lower line at the wheels upper line estimated flywheel. Quote Link to comment Share on other sites More sharing options...

Those are RWHP, right? Ah...think they are estimated flywheel...I know Ian's powertrain loss was only 8% but most seem to think the manual loses 15-20%!! (I think you all need to put some air in your tyres lol) Ian got 580RWHP....http://www.mkivsupra.net/vbb/vbpgimage.php?do=full&p=1497&d=1142339607 But either way can't give you a graph Quote Link to comment Share on other sites More sharing options...
matt k Posted July 26, 2007 Share Posted July 26, 2007 Jake, whats the use if you can't use that power and put it to the road on everyday road conditions. You'd probably leave most Grande powered singles round a track. Not with racing drivers and a well set up car. Quote Link to comment Share on other sites More sharing options...

Guest Terry S Posted July 26, 2007 Share Posted July 26, 2007 you need to be careful you are comparing apples with apples guys. All manifolds should be the same material etc, preferably the same dyno. Quote Link to comment Share on other sites More sharing options...

rob wild Posted July 26, 2007 Share Posted July 26, 2007 That looks interesting just comparing it to my dyno result Just out of interest you labelled yours as GT60 was that your PHR stage 1? Quote Link to comment Share on other sites More sharing options...
Wez Posted July 26, 2007 Share Posted July 26, 2007 That looks interesting just comparing it to my dyno result Just out of interest you labelled yours as GT60 was that your PHR stage 1?

rob wild Posted July 26, 2007 Share Posted July 26, 2007 I thought :- PHR Street turbo is GT60 PHR Stage 1 turbo is GT61 Just though he may have meant a GT60 series turbocharger? Quote Link to comment Share on other sites More sharing options...
dandan Posted July 26, 2007 Share Posted July 26, 2007 I thought :- PHR Street turbo is GT60 PHR Stage 1 turbo is GT61 Both are the so called GT60 Quote Link to comment Share on other sites More sharing options...
