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
