True, though I am not comparing those two. I am comparing a full flow external style cooler to my modified stock oil filter housing w/ custom separate oil cooler loop.

Some documentation on catalyst substrates. https://www.dieselnet.com/tech/cat_substrate.php https://www.dieselnet.com/tech/cat_subs_met.php http://www.hypercat-acp.com/catalytic-converters.html The metal wound have less substrate and larger orifices, sacrificing emissions as you pointed out...

You could probably ask them to do a mangaflow 3" ceramic core instead of the 2.5". Work on their end would be the same, they would just need to order the larger universal cat, cut to the same length and weld on a larger flange. Heck I could weld up one for you! I did the exact same thing for...

lol Confirmation! :D

I would start with the measurements to see if that idea would even work or not. Another simple option is to cut the pipe in half between the resonator and hanger. Right at the point where the nose of the differential bolts up. Have a good welder add in a 1" piece there to shift everything back...

Easiest fix for the cascading upgrades syndrome is vehicle replacement :D

Hard to tell from the photo but is there enough room for the resonator to move back about 1"? Is it going to run into the diff or the subframe? It looks like if that 90° Bend was pushed back about an inch it would clear the arm mount / subframe mount. Then you could align everything better and...

Neat, the internet is full of garbage. The real question is who is the idiot running 5W-30 engine oil in a -40°F climate? Go to BTIOG for real oil information. The real problem is the inability for people to filter out the garbage information from the facts. If you are hanging around social...

I am not saying you have a wiring issue from the battery to the ECU or injectors, I was just expanding on what Pi said above. A multitude of things can cause lower voltage, I was just explaining how the ECU handles firing the injectors under different voltages. Right now I would focus on your...

Its a correction factor so the injectors will still flow the same amount of fuel even if the voltage is lower. This is due to the delay in response of the coil in the injector. This requires the ms of requested opening time of the injector to be increased to compensate. If the voltage to the...

Is there going to be another run of parts needed to program the stock TCCS system? Otherwise I will be picking up a MS3Pro Ultimate Standalone shortly. My build should be progressing quickly as spring comes around. Trying to find out if the programmable TCCS system is going to happen or not.

Why would you only associate a pressure drop at a lower flow idle condition? Trying to understand your thinking behind this. I have also mitigated potential losses in all the banjo bolts in the stock system as well, FYI. They are no longer stock, per say. All the orifices have been enlarged...

Yeah the gauge is basically useless. You would need to install a pressure transducer and log the output with a data logger.

Yes. The 3 spacers should have the black ring on the rail side. http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=89

12.17 volt measurement is really meaningless. That is just telling you the wiring is capable of a voltage sense to the battery, NOT under any load. The 9.61 volt reading is the clue telling you something is wrong. Also, where are you taking the pump voltage reading from exactly? At the pump...

Pi it would be tough to accurately answer that question. I do not know the actual gallons per minute the 7M engine oil pumps through the system. Someone could set up a test stand and spin the pump under pressure to measure the flow output. But the chances of someone actually doing that are...

Go for it. :D Just remember to give a mention back! :thumbup::icon_lol:

Braille? Shorai? Super B? Have you measured the alternator output when you are using everything on high? Just curious how close to max output you are coming, sounds like a hefty load.

NICE! Yeah that's plenty. :D

Yeah external mounted, just 3 extra fittings on the pan. 1 feed, 1 return and 1 for the temp sensor.
