Hello folks,
Want to update you guys on the project that we have down under in Melbourne, Australia. As many of you might have known that we were putting nismo S1 engine parts into my car and the job has finally been done this morning and I finally got to drive the car after a long 2 months wait (including X'mas holidays)... Special thanks to HyperTech's Andy and Eric (aka Eric's Engineering) and Peter/Nathan from Sydney for giving out information from their racing experiences.
To recap you guys on the mods that I had BEFORE the project.... here are the parts and the wheel power I got from them... (Please note that Aussie wheel power numbers are generally lower than what you guys have got in the States, because we are using different dyno machines!)
Performance Parts I had on my car BEFORE S1 parts were put in:
1. Nismo Cat Back Exhaust (US Spec. from Jason at Perf. Nissan)
2. Crawfard Cats (from Doug)
3. JUN Lightweight flywheel
4. UR Crank Pulley
5. K&N Filter
6. UniChip piggy back ECU
And I got around 167rwKW, which is around 227.2 rwHP with all of those 6 mods. from the stock engine... this one was tested by APS Peter at his APS headquarter down here in Melbourne. So before we tuned the car, we had a dyno run again at HyperTech machine and it produces 169.4rwKW, which is around 230.3 rwHP, not far from APS's dyno, so this was used as the base dyno for this project.
Then we put in the following parts to build a better N/A engine, the goal is to rev the engine higher and safer:
1. Nismo VTC Units (55 degrees)
2. Nismo S1 Spec Cams (Int 276 degrees, Exh 256 degrees)
3. Nismo Valve Springs
4. Nismo Con-rod Bolts
5. Fujitsubo Headers
6. MoTeC M600 ECU (to replace UniChip)
7. MoTeC Drive by wire module
8. MoTeC Cam Control Module
9. MoTeC sensors + wires
With those mods, the car sounds like a racing car, most likely due to those higher angle cams and the headers.... car sounds VERY mean and deep... with the exhaust pluses that can be heard when the car is idling at the stand still position (like a WRX with exhaust)...
The car revs up higher up to 7200rpm and with fuel cut set at 7300rpm to be at the safe side.... we are producting at 195.1rwKW, which is around 265.3 rwHP.....
Do a simple calculation... the net gain from this project with those nismo parts + motec..... is 265.3 rwHP - 230.3 rwHP = 35 rwHP
Eric (the tuner at HyperTech -> http://www.pow.com.au/eric.htm) tried many combination of the cams positions and the VTC angels too to get the best out of this car considering this is a STREET car with Air Conditioning being operated everyday.... he told me that he was actually expecting more from those mods, but that's what he can do to a STREET car.... and only if I don't want to have the A/C operating or running poor idling, he could still make quite a fair bit of HP from this car...
And also the only way to make more HP from the current state will be making better intake for those cams to run better... so we might be making some in take tubes and using those plenums/spacers available on the market to make further HP.... I am not too sure at this stage what can be done to make more HP without opening up the engine again or giving it FI (which I would not like to go for after days of days of thinking before the project)...
Hope all of those numbers help some of you guys to decide what to do next with the N/A mods...
ps. MoTeC is the best option we could think of for this engine job... you just need to know who knows MoTeC best and we can handle the job.... MoTeC hardware isn't expensive comparing to other systems out there really... just need to find someone who has experiences with MoTeC before, and you can save some big money!
Here are some dyno charts we generated:
