Josh Posted April 30, 2011 Author Share Posted April 30, 2011 nice result , im glad you were happy with the service and your results . Rich. Thanks! Nice to meet someone else off the forum. When I saw the Supra as I pulled up I thought "Ooo, I wonder if it's someone off the forum". I completely forgot that you were at Dynodaze. I'll be back to see you once I've gone BPU Quote Link to comment Share on other sites More sharing options...
Kirk Posted April 30, 2011 Share Posted April 30, 2011 Yep deffo a US dyno. Im going to put my car on that dyno and see how much more power is hidden away Quote Link to comment Share on other sites More sharing options...

Homer Posted April 30, 2011 Share Posted April 30, 2011 The torque curves look good, but you mentioned it is not BPU yet, this begs the question - How much boost was it making on the day? Quote Link to comment Share on other sites More sharing options...
Abz Posted April 30, 2011 Share Posted April 30, 2011 Got a boost gauge all ready and it seems to hold at about 0.9bar. I'll look at getting an AFR gauge too. Thanks The torque curves look good, but you mentioned it is not BPU yet, this begs the question - How much boost was it making on the day? Think Josh said 0.9, but I remember when I did mine at SRR it stated what boost it was running on the dyno sheet? Quote Link to comment Share on other sites More sharing options...

Bleeding 'ell, I read the thread 3 times looking for the boost level and still missed that! Seems about right for 0.9 bar, maybe a little on the high side but not so much. The torque curve looks good and strong, which is the important part. Quote Link to comment Share on other sites More sharing options...
Attero Posted May 1, 2011 Share Posted May 1, 2011 You gained over 25hp from just the exhaust (and a one decat?)? Quote Link to comment Share on other sites More sharing options...
Abz Posted May 1, 2011 Share Posted May 1, 2011 You gained over 25hp from just the exhaust (and a one decat?)? The cats are very restrictive! I got 352bhp from just removing both cats! And having a restrictor ring put in. Quote Link to comment Share on other sites More sharing options...

Nic Posted May 1, 2011 Share Posted May 1, 2011 (edited) You gained over 25hp from just the exhaust (and a one decat?)? Seems about right for a Supra running a 0.1bar pressure increase and a less restrictive exhaust. Are the turbos running sequentially, the power curve looks very linear?

Nic Posted May 1, 2011 Share Posted May 1, 2011 Yeah, sequentially. Would the fact that they're UK Specs make any difference? The UK and J-spec power curves both drop off at the transitional point when the second turbo comes on line. These are not stock turbos but you can see what I mean on THIS dyno plot.

These are not stock turbos but you can see what I mean on THIS dyno plot. As I've never been in any other Supras at WOT then I'm not sure if mine feels the same but when the 2nd turbo comes in it feels smooth and there's only a slight feeling of hesitation (0.5secs or so) then you can feel the extra power of the 2nd turbo but it's not a burst of power, feels like a very smooth transition.

Ian C Posted May 1, 2011 Share Posted May 1, 2011 I'd say the power delivery will still be relatively smooth for such a modest boost increase. It's when you double the boost pressure at transition to 1.2bar you feel it and get the spike on the dyno graph. Of course I've been wrong before Quote Link to comment Share on other sites More sharing options...
scotty71 Posted May 1, 2011 Share Posted May 1, 2011 (0.5secs or so) then you can feel the extra power of the 2nd turbo but it's not a burst of power, feels like a very smooth transition. I get the very slight hesitation as you but then when Turbo two kicks in its a raw bpu burst of power Would be interested to see what mine does on this dyno Quote Link to comment Share on other sites More sharing options...

I'll let you know when this is and we can see whose is the best Nice one Josh, good strong result. Thank you Now let's go fit the 2nd decat!

Scott Posted May 1, 2011 Share Posted May 1, 2011 Looking good. What is the stock torque figure? I had it in my head stock was around 325, would that mean this is up in power but down in torque? Quote Link to comment Share on other sites More sharing options...
bignum Posted May 1, 2011 Share Posted May 1, 2011 (edited) I'd keep it like that if it was me And i would:) I did tell josh about the slippery slope...... looks like he`s on it:D Either that or he`s folded due to the peer pressure.

Josh Posted May 1, 2011 Author Share Posted May 1, 2011 And i would:) I did tell josh about the slippery slope...... looks like he`s on it:D Either that or he`s folded due to the peer pressure. Nope Just came in from putting the 2nd decat on. That was a b!tch of a job! Just jacking the car up and using axle stands stands didn't get it high enough so most of it was done by feel. I've all ready got the boost controller so I just need a SMIC and FCD and then I'm leaving it at BPU Quote Link to comment Share on other sites More sharing options...
welshbuddy Posted May 1, 2011 Share Posted May 1, 2011 hey josh, how much of an increase you looking at scince the work done? scince the last dyno ? 356 is still abit ! Quote Link to comment Share on other sites More sharing options...
Josh Posted May 1, 2011 Author Share Posted May 1, 2011 hey josh, how much of an increase you looking at scince the work done? scince the last dyno ? 356 is still abit ! Should be about 500bhp with the 2nd decat give or take a few bhp. only kidding Not sure really. I'm hoping for around 400 when at BPU but we'll have to wait and see Quote Link to comment Share on other sites More sharing options...
johnny g Posted May 1, 2011 Share Posted May 1, 2011 With a double decat + exhaust, you'll see around 375bhp IIRC Quote Link to comment Share on other sites More sharing options...
