Supra ST Myster Posted August 27, 2007 Share Posted August 27, 2007 See pic, im well dissapointed to be honest after the SSR day. 0.6bar on a single, think its a "t61", its on stock 440s and ECU and afrs are 10.9-11.0 on WOT Also car is an auto. These are at the wheels figures btw Link to comment Share on other sites More sharing options...
Lewis Posted August 27, 2007 Share Posted August 27, 2007 might want to give people your spec mate but based on your single and what you have done before, I would say it isn't great somehow! Link to comment Share on other sites More sharing options...
Homer Posted August 27, 2007 Share Posted August 27, 2007 Is your's an auto Emin? (I forget), as that would be a rwhp figure. If it's an auto, I think it's about right. The stock ECU simply cannot fuel for a single, it'll massively overfuel and kill your power. Mine on the stock ECU and 440's at 0.8 bar (this is on a bigger turbo too) was slower than it was at BPU.

Jake Posted August 27, 2007 Share Posted August 27, 2007 It's just on the stock ECU? Link to comment Share on other sites More sharing options...
Supra ST Myster Posted August 27, 2007 Author Share Posted August 27, 2007 It's just on the stock ECU? yeah, all stock, i can pull in a bit more power as afrs are still a bit rich on WOT, but going to wait till bigger injectors are in and different ecu.. whats your point though?

Chris Wilson Posted August 27, 2007 Share Posted August 27, 2007 Next document will be a death certificate, it needs a mappable ecu, pronto! Link to comment Share on other sites More sharing options...
Supra ST Myster Posted August 27, 2007 Author Share Posted August 27, 2007 not doubting you, but can you explain why if the afrs are ok at the moment? Link to comment Share on other sites More sharing options...
Scooter Posted August 27, 2007 Share Posted August 27, 2007 Chris how long and how many miles do you think the engine would stand in this spec? If there's no det and no excessive overfueling what will kill it? Link to comment Share on other sites More sharing options...
Clarkey Posted August 27, 2007 Share Posted August 27, 2007 It's an XS Power turbo isn't it ? Emin, post the chart plotting the AFRs. Link to comment Share on other sites More sharing options...

Jake Posted August 27, 2007 Share Posted August 27, 2007 whats your point though? Well, what is it that you're "well disappointed" with? If I understand correctly, you're running a single on stock injectors at sod-all boost and the map with stock twin turbos - right? No wonder it's disappointing. It's bound to run worse than stock and TBH Em I'm slightly surprised you haven't blown the motor yet. You're a braver man than me though mate, putting the poor thing through the torture session of a dyno day. Link to comment Share on other sites More sharing options...
Supra ST Myster Posted August 27, 2007 Author Share Posted August 27, 2007 why would it blow if its low boost and afrs are not a problem?? nobody is answering that question for me.. and if its less than stock twins again where is the harm?

Wez Posted August 27, 2007 Share Posted August 27, 2007 These turbos can hit 1.4bar by 3500rpm so I would be very very careful in upping the boost anymore. Your fueling looks ok from 4500rpm at the moment, maybe a little rich but its the area below that which really could cause you some damage, I found my 440cc properly mapped with the AEM were ok upto approx 0.8bar with increased rail pressure.

Supra ST Myster Posted August 27, 2007 Author Share Posted August 27, 2007 plus the car has been like this since last september and it runs good with no problems? I just thought it would be more than that as it feels faster than bpu, maybe not then. Link to comment Share on other sites More sharing options...
Homer Posted August 27, 2007 Share Posted August 27, 2007 Well the afr's actually look okay, which is very surprising (One thing I learnt this weekend is they read quite a bit richer on the dyno than on the road). Any single turbo is going to be well outside its efficiency range at such a low boost so it won't be producing much power. You need to get the boost up and work from there (obviously after a new ecu and injectors) The XS power turbo's are hopeless though, do you know which one you have? any pics?

Wez Posted August 27, 2007 Share Posted August 27, 2007 I take it these XS power T61s dont perform like a PHR Stage 1 then Link to comment Share on other sites More sharing options...

Homer Posted August 27, 2007 Share Posted August 27, 2007 I take it these XS power T61s dont perform like a PHR Stage 1 then The XS T60 has a 51mm compressor so it might as well be called a T51 Link to comment Share on other sites More sharing options...
Clarkey Posted August 27, 2007 Share Posted August 27, 2007 Well the afr's actually look okay, which is very surprising As you say, because of the low-boost. Abit less power to stockers running 0.8 bar with the cats in place isn't it ? Question: At 1.4 bar - that XS power turbo be delivering similar power/just abit more to a decatted pair of stockers running 1.2 bar ? Link to comment Share on other sites More sharing options...

Homer Posted August 27, 2007 Share Posted August 27, 2007 this is the turbo, it doesnt say on it what it is though, It's not one of the horrid T04B turbo's thank goodness! Looks like the T60 or T70 ones, do you have a caliper gauge to measure the inducer on the compressor? It'd confirm which one it is. Link to comment Share on other sites More sharing options...
