update: X piped + PowerSteering fix and cooler + inbox pod filter

well... havent update the blog for a while... so here we go:

first i would like to thank dan / C2888 for his help and advice... and also thx u for this cool as low ramp for my car!!! ^_^






X pipe to fix the torque loss
first is the torque loss that i saw on the previous dyno result. caused by loss of back pressure in the APS tru twin system...

so i decided to fix it with Magna Flow 'X' Pipe...

here it is. its designed to balanced the flow between 2 pipes without restricting it on the top end... it works great for V8, but i dunno whether its gonna work for VQ35 V6... i guess only one way to find out...

the pic of the installation:


the dyno result (mod: K&N panel + APS cat back + X pipe):

dont worry about the output number, its done on same dyno, but its 3 months apart.... if you look at the power curves, i got alot more usable power across the rev range... and on the torque curve, it climb alot earlier and no more torque drop....

my conclusion:
after the X pipe, from 6000-6600rpm felt abit restricted compared to before. but i felt lot more torgue from early rpm... and the car pull constantly accross the rev range. also the noise a lot quieter compared from before...

the most important thing is the car pulling harder and alot more power across the rev range, although the max kw is pretty much the same...




Power Steering Pump Replacement
few months ago i blew my power steering on some drift practice.... since then i've gone thru 4 trackdays without power steering and its killing my arm.... finally ordered one from wreckers in sydney ($300, saving me $$ - from nissan was $1035)

so lets start:
1. loosen the belt tensioner and the idler pully bolt. remove the belt...

2. remove the air filter box and radiator fan assembly...
3. remove upper radiator hose...
4. remove the high pressure and low pressure hose from power steering pump.

5. remove the 2 bolts holding the pump. on of them is behind the pulley... (thx to dan for helping me pulling this damn pump out... )
6. swap the pump and install in reverse order.

7. top up the power steering fluid with dexronIII compatible (auto transmission fluid)
8.bleed the hydraulic system on the power steering:

• turn steering to each lock positions few times
  
• turn engine on if it making noise, turn it off and keep doing the first step
  
• while engine on, turn steering to each lock position 3 times and hold it 3sec on each lock possitions, dont hold it too long... inspect bubbles generated in the reservoir tank.
  
• if there is bubble, turn engine off and repeat the whole process when the bubble is gone.
  

9. top up the radiator and connect everything back. remember to top up the radiator properly, no air bubbles...




Power Steering Cooler
i use Hayden transmission cooler to replace the stock 350z power steering cooler...


first i remove the stock cooler...


size comparison...


mount the new cooler with the new hose and clamps


i reuse the stock mounting position and used the plastic clip that comes with the kit...





What Pod Filter officer?
well, i had the custom pod filter bracket and the heat shield and still get trouble from the boys in the blue... so after purchasing an extra airbox for a while now, i decided to modify my stock airbox and fit the pod in there.... hopefully

this is how it looks before... (rush job, highskool project... )


now lets start: first i split the airbox into 2.... yes you can prey it open... its not reversible tho unless you have a strong plastic glue...

with the front airbox piece, test fitting and measuring the distance with the pod filter...


here is the back piece... i will mount the pod to that holes at the back but first i need to cut the box abit in order to make the pod fit in there


here is the pod mounted to the back piece of the airbox and few small holes cut so i can fit small spanner to tighten the bolts...


then connect the front and the back piece of the airbox. i didnt want to glue it, coz i still wanna clean my pod filter in the future so what i did i just drill few holes and cable ties the two piece of airbox together


frontal look of the pod inside the box.


now the cover of the box


i had to cut the bottom part and shaved abit from behind the top cover...



pod in the box, with cover...


installed back to the place... i will figure out how to cover the remaining holes its only abit... not much...




thx to dan for his help and advices... thx to mic for holding my bumper thx to shaun for not farting while im under the car... thx for ying, jally, kenny, jason for the company... exe-crew garage rules
