Samurai 20V Posted May 9, 2015 Share Posted May 9, 2015 (edited) Hi Chaps.. Engine Type - TT Engine Spec - Stock Turbo - Stock Fuel Used - 95 Pump fuel Exhaust - Kakimoto catback & double decat Transmission - V160 ECU - Stock Power figure - 216wkw/290whp Torque figure - 431nm ( not sure if this is right) Boost Pressure - 1 bar Run was in 4th gear ( Car usually makes 1.2 bar in 4th, not sure why it did not make full boost) Made lower figures with water spray turned on). Ambient was about 29deg with 77% humidity.. Car is in TTC as issues with IACV Do u think the figures are as per a normal BPU? Or should I be worried?

tony tt Posted May 9, 2015 Share Posted May 9, 2015 Something wrong there id say. Figures are low for bpu at the wheels. Surely you don't lose 110hp from fly to the wheels? Quote Link to comment Share on other sites More sharing options...
safcdixon Posted May 9, 2015 Share Posted May 9, 2015 Id agree with Tony, mine made 330ish at the wheels at bpu, numbers seem low Quote Link to comment Share on other sites More sharing options...

He was only at 1bar though and not all bpu supras make 400bhp. Another thing to think about is the temperature during the run. A car wont make maximum power in hot temperatures. Also the run was on 95ron fuel which will affect the figure. Depending on the transmission loses 290whp is about 350bhp ish?

tony tt Posted May 9, 2015 Share Posted May 9, 2015 Could it be the 95ron that it showing low? - - - Updated - - - He was only at 1bar though and not all bpu supras make 400bhp.

Benjy Posted May 9, 2015 Share Posted May 9, 2015 Mine made around 380bhp @ 1bar. So circa 310ish @ the wheels. + the 95ron at 29 degrees ambient air temp, 290's about right I'd imagine. Quote Link to comment Share on other sites More sharing options...
Hitbox Junkie Posted May 9, 2015 Share Posted May 9, 2015 Did not think Supras could run 95 :/ Run it on Vpower and see a difference in the figures Quote Link to comment Share on other sites More sharing options...
safcdixon Posted May 9, 2015 Share Posted May 9, 2015 Did not think Supras could run 95 :/ Run it on Vpower and see a difference in the figures Hes in south africa not sure if its available over there Could try an octane booster of some sort though Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted May 9, 2015 Author Share Posted May 9, 2015 Hi guys, Thanks for all the replies. I was a bit worried the car is not right, but it pulls like a steam train on the road. We don't have 98 Ron here, only 95... Hence I am using water spray, but it made less with the spray on.. Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted May 9, 2015 Author Share Posted May 9, 2015 Next for me is to map the car with Ethanol, but first gonna replace the vsvs and Iacv valve to stabilize the boost... Quote Link to comment Share on other sites More sharing options...
Scott Posted May 9, 2015 Share Posted May 9, 2015 Should be a 3rd gear pull.... not 4th. You're looking for a 1:1 ratio on the pull. It seems a bit all over the place, are the dyno operators inexperienced? Torque looks low too. Did you hit 1.2bar on your way home? Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted May 9, 2015 Author Share Posted May 9, 2015 Ok, didn't know that it should've been 3rd. To be honest, there are few good dyno operators where I live.. This one is not one of the best.. Car was 1bar in 2nd, 1.15 bar in 3rd and just hit 1.2 in 4th... It feels awesome on the road... Quote Link to comment Share on other sites More sharing options...
Scott Posted May 9, 2015 Share Posted May 9, 2015 You maybe need to up the gain a little bit. You should easily see 1.2bar in 3rd. Is it an EBC you have? Quote Link to comment Share on other sites More sharing options...

Samurai 20V Posted May 10, 2015 Author Share Posted May 10, 2015 Yes Scott, I have a hks evc.. I have it set like that so I get 1.25bar in 5th gear.. If I increase the gain, it overboosts in 5th and 6th.. Quote Link to comment Share on other sites More sharing options...

It's possibly something to do with being in TTC mode then. I never had any issues hitting 1.2bar in 3rd through 6th when the gain was set correctly. The gain should bring the boost in hard but the boost setting should pull it back down again. Is the boost set at 1.2bar or is it a %age setting?

Samurai 20V Posted May 10, 2015 Author Share Posted May 10, 2015 Boost is set at 1.2 bar, not % setting.. I have some vsv and a iacv valve coming from Japan, as soon as these arrive will return the car to sequential mode.. Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted May 10, 2015 Author Share Posted May 10, 2015 I need to get the car right before I get it mapped which is in 2 months time.. Quote Link to comment Share on other sites More sharing options...
jumpbike Posted May 16, 2015 Share Posted May 16, 2015 Should be a 3rd gear pull.... not 4th. You're looking for a 1:1 ratio on the pull. 5th is a 1:1 ratio... Quote Link to comment Share on other sites More sharing options...
Scott Posted May 17, 2015 Share Posted May 17, 2015 5th is a 1:1 ratio... Oops yeah, 5th. I got 3rd from the Auto Apologies Samurai, should have been a 5th gear pull Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted May 17, 2015 Author Share Posted May 17, 2015 Oops yeah, 5th. I got 3rd from the Auto Apologies Samurai, should have been a 5th gear pull Thanks, will re do the run to see the difference... Quote Link to comment Share on other sites More sharing options...
Samurai 20V Posted July 11, 2015 Author Share Posted July 11, 2015 (edited) Ok, went back to the dyno today.. Same dyno, same conditions.. Difference with the car was changed all the VSV's, and the two rubber link pipes and returned to sequential mode from TTC. Car was at 1.1bar roughly, it does not want to make more boost than that on the rollers, it makes 1.2 bar + on the road. Overall, I am happy with the gains, as the car feels insane, and noting this is on 95 and water spray.. The car made 10kw less with the water spray off, so I am glad that its doing its job finally (change point here was that I brought the spray in at a later boost). I realised that I cant dyno in 5th gear as I still have the speed limiter, will dyno again once the speed cut is fitted.

Scott Posted July 12, 2015 Share Posted July 12, 2015 Those figures still look incredibly low to me bud. Of course, what matters is the bum dyno..... but I'm still confused with what you are seeing. I take it the figures are at the wheels? If so it's not THAT low and it may be down to the 95 ron fuel. The torque seems low on the dyno though.
