Hussein's 1998 V70 Xr : The Force Awakens

Installed the 1000cc Bosch Injectors today (bought them April of 2012, took awhile to get there), and a 160ºF T/stat. Now I have to see if TT can reset the cooling fan onset parameters, since operating temp is still around 200ºF.

recalibrated in TT for the larger injectors, about 35% leaner. Feels good so far. Have to drive it some more to get the adaptive settled in.

Where did u find a 160deg t stat? Is that a worthy change? What can be gained from that?

On Amazon or RockAuto. Bought 2 a couple of years ago. I'll look up the PN later. I wanted to see if I could drop operating temp, since on extended pulls the coolant temp will rise 2º every few seconds - I was up to about 215º I think by the 3rd dyno pull, and that was with a 180º t/stat.

I think there is no point unless cooling fan onset is modified in the mapping, since the t/stat will simply peg full open - it likes to run around 195-200º. I haven't asked Adam @ TTusb if he can adjust it for me yet - with VEMs I would imagine I can set it to whatever I want.

Amazing stuff. Almost time to update your sig again, your currently stated HP is way off :D

Yes, thank you for the reminder!

Did you do any tuning on the dyno or were you just looking to get numbers?

No tuning, I already knew the injectors would be maxxed out, I just wanted to redo (April dyno) with a working clutch. I didn't make any other hardware changes.

Now that I have access to a reasonably priced AWD dyno, I can make sequential changes & go dyno without costing me a fortune.

I'm not sure I even want to tune on the dyno, unless there is a way he can adjust the loading to reflect the turbo's spool characteristics - going WOT under 3K just brings on the timing pull seen in the plots. I have to press him on that issue.

Picking up the surge tank & extra Bosch 044 this afternoon -

that's be the next mod with increased ID fuel lines & Aeromotive FPR. Reworking the fuel lines on the AWD saddle tank had held me back from doing the previous idea -

so I'm glad I held off - the surge tank seems like a much safer approach - pumps are submerged for cooling, won't risk cavitation, etc.
