a98pmalcolm Posted February 10, 2016 Share Posted February 10, 2016 (edited) I've had facebook messages an PM's over the years so I thought it was about time that I made a little graph dyno read out thread showing the progression of different power stages.. As you all know if you were to the exact mods I have done over the years your results will be different but, I hope this thread will guide people on what they need to do to achieve there power goals. Or you may just like looking at graphs as we all do So I have spent a few hours digging out, scanning the graphics, resizing them and typing this up.. I have typed out the basic mod list needed to achieve the power I did, so no clutch, brake or anything like that in the specs. I'm also going of memory lol. Here we go: Spec: OEM 2JZ block and head. 6 Speed Manual 264 9.3mm Whifbitz Road Cams AEM Water Cooled Injection Fuel Pulsator Bypass Blitz Boost controller Double De-cat HKS Exhaust Cone Filter 255 Walbro pump Power at flywheel - 406.2 bhp After this it was time for my next big thing so after I have been reading Syvecs ECU was the safe and future proof side of things. Upgrade: Syvecs ECU NTK L2H2 (LZA-09-E1) Wideband Lambda Sensor Ryan reassured me that TTC was the way forward on a ECU with a good map, even though I had run TTC on a stock ECU and thought it was absolutely awful I gave him the benefit of the doubt and he wasn't wrong. TTC when mapped to syvecs felt great, and great is an understatement. Look at the power curve in the graph below and you will see how nice it is on TTC. The 1st graph is wheel power at 363.3 bhp. The following graph is 433.6 bhp which is flywheel power. So in this case we see about about a 20% loss through drivetrain. Very surprising.... At this stage Ryan explained that the j spec injectors (440cc) were now restricting me from getting more power... So without further ado the hunt began for some drop-in injectors. I came across some 680cc SARD injectors and fitted them in. Upgrade: 680cc SARD injectors This could have been the base map Ryan e-mailed over or one he used to test the injectors, I'm not really sure.. But it was the 1st run 382.3 bhp And then the main run, and what an outcome on Stock J-spec turbos 455.5 bhp Ryan an I were very happy with the car. It felt great, syvecs traction worked flawlessly. And was extremely smooth delivery.. But was we all get, it didn't take long for the thrive for more power and on the off chance I was messaging JamieP about something, I cant remember now. But he bought to mention he maybe breaking the black beast... So... I called dibbs on some items if he does So sadly we saw that car break but in the bigger scheme it improved many other cars. Upgrade: Precision Turbo 6766 DBB Whifbitz twin waste gate manifold Twin turbo smart 42mm Wastegates 4" downpipe Whifbitz 4" midsection AKS connections and adjustments Still using HKS super silent back box NGK grade 8 plugs As we can see below a 18% loss through drivetrain 550.9 bhp.@ Wheel 649.4 bhp @ Flywheel We were hopping bigger figures but with Jamie running well over 1000bhp in the black best he had stronger wastegate springs causing issues So as normal I rush to sort everything out, knowing that theres more power with the wastegate issue resolved. I got on the phone to Paul and ordered the stock 7PSI springs I also had Pauls uprated coil packs Upgrade: 7PSI waste gate springs Whifbitz coil packs The result, better 680.9 bhp @ Flywheel At this point the 680cc injectors were restricting any more power. 680 bhp I was happy to stay at but I wanted to have the big polished inlet, top feed injectors with a snazy fuel rail etc. Mainly for show to finish off the engine bay, but it would be rude not to go for bigger injectors right? Upgrades: SRD plenum inlet manifol SRD fuel lines Whifbitz fuel rail (had it resprayed in bayside blue ) ID1000cc injectors Fancy pants Q45 TB from the gold rush supra Mishimoto Alloy Radiator Walbro Fuel 450 Pump Aeromotive fpr As Ryan has moved from the country it was easier to have someone with the car while mapping, I came accross a very helpful chap called Romain who also works for syvecs and we has a nice result. 646.9 at the wheels We didn't have a flywheel number but Romain agreed we would see about a 17% loss though drivetrain so approx 755 bhp at the flywheel. Judging by previous read outs 17% would be about correct. Well that's it. I hope some of you find this useful or enjoyed reading, took me bloody hours to do and remember the mods ect. Thanks for looking Paul Edited February 11, 2016 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...
supra_ufo Posted February 10, 2016 Share Posted February 10, 2016 Very nice work mate I am interested in your syvecs and drop in setup as its something I want to do, i have a rebuilt stock jspec setup at the moment. I cant afford to go single but eventually thats what I would like. I am loving those figures, is yours a 6 speed? Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 10, 2016 Author Share Posted February 10, 2016 Yes mate 6 speed Thanks Quote Link to comment Share on other sites More sharing options...
Frank Bullitt Posted February 11, 2016 Share Posted February 11, 2016 Thanks for the info Just trying to follow the printouts, the 433.6 flywheel was sequential and jumped to 455.5 flywheel when put in TTC mode with the 680cc injectors added?

j_jza80 Posted February 11, 2016 Share Posted February 11, 2016 Great writeup Now,if you can be bothered... plot that data into an excel chart. That'll give you a great indicator into how the powerband has been affected by the changes. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 11, 2016 Author Share Posted February 11, 2016 (edited) Thanks for the info Just trying to follow the printouts, the 433.6 flywheel was sequential and jumped to 455.5 flywheel when put in TTC mode with the 680cc injectors added? It was TTC on both. Injectors bought it up to 455 mate Edited February 11, 2016 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...
MATT RR Posted February 11, 2016 Share Posted February 11, 2016 great write up, really helpful this and great food for thought which is handy for people like me who don't know which way to go at present! As Jay said if you can be arsed it would be great to see all those results trended in Excel table with a graph showing each power band color coded lot of work though Quote Link to comment Share on other sites More sharing options...

Noz Posted February 11, 2016 Share Posted February 11, 2016 Be good for you to do a table of results, comparing power increase so you could see the increments changing with adjustment components. Be clearer than listing the dyno themselves. Good work mate, great write up. I want to see a nerd table of stats because this information here is great! Can't beat data. Makes me feel proud to be a supra owner to see a follow driver actually using data and not saying "approx ###bhp". Hate seeing that, mainly on FB!

Scott Posted February 11, 2016 Share Posted February 11, 2016 That's some brilliant data that, great information. Would be good if you got a chance to do a power run on SRR so that all the power runs can be from the same dyno (no 2 read the same unfortunately). Brilliant work Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 11, 2016 Author Share Posted February 11, 2016 Cheers fellla, nice to know this post is appreciated. Yer scott would be good to get it on SRR and get the fly wheel and wheel power from that dyno. Will have to keep an eye open for when there is a dyno day or something.

ianhid Posted February 11, 2016 Share Posted February 11, 2016 This is massively useful! Trying to spread out costs and work out if it was actually worth putting a Syvecs in while still on OEM turbos. Certainly looks like it would be if I updated fuelling a bit as well. Also means if I later go full retard single turbo, I already have the ECU. Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 11, 2016 Author Share Posted February 11, 2016 Exactly how i did it mate. Spread the costs and gives you options.. Quote Link to comment Share on other sites More sharing options...
Pudsey Posted February 11, 2016 Share Posted February 11, 2016 Great read that as others have mentioned. It's interesting that the response has improved, as you would have expected it to go the other way. Super bit of reference material Quote Link to comment Share on other sites More sharing options...
Scott Posted February 12, 2016 Share Posted February 12, 2016 Great read that as others have mentioned. It's interesting that the response has improved, as you would have expected it to go the other way. Super bit of reference material I can't see the pictures so I'm not sure which graph you are referring to but if it's the last one that one was TDI where it uses a hub dyno. They allow more initial load as I understand it which makes the result more comparible to the actual road. More load on the engine means more work which leads to boost coming on earlier Quote Link to comment Share on other sites More sharing options...
Glanza_Mike Posted February 12, 2016 Share Posted February 12, 2016 Nice mate, great thread! Did you prefer the way the car drove in it's mapped TTC version compared to sequential? Quote Link to comment Share on other sites More sharing options...
Dim Sum Posted February 12, 2016 Share Posted February 12, 2016 Nice power figures. Just wondering what boost are you running now? Quote Link to comment Share on other sites More sharing options...
a98pmalcolm Posted February 12, 2016 Author Share Posted February 12, 2016 Nice power figures. Just wondering what boost are you running now? 1.7 mate Nice mate, great thread! Did you prefer the way the car drove in it's mapped TTC version compared to sequential? I only ever had it TTC on syvecs never had it on sequential with syvecs bud Quote Link to comment Share on other sites More sharing options...
Glanza_Mike Posted February 12, 2016 Share Posted February 12, 2016 Ahh okay, and did you prefer the syvecs ttc to the normal sequential? Quote Link to comment Share on other sites More sharing options...
Sheefa Posted February 12, 2016 Share Posted February 12, 2016 1.7 mate I only ever had it TTC on syvecs never had it on sequential with syvecs bud Ahh okay, and did you prefer the syvecs ttc to the normal sequential? I asked Ryan G a while back mate if he could map a car on Syvecs keeping the sequential setup. It can be theoretically done, but he advised would be a right PITA and TTC was a much better option anyway. Don't think I've seen anyone running a sea setup with Syvecs although am sure Chris Wilson said someone was running a Motec on a seq setup.
