Lambda is universal measurement, .714 is 10.5 to 1 AFR on 91-93 octane. I originally saw .69 and that’s to Rich, I am targeting, .72 to .74 lambda now and adjust Fuel pressure to provide that Wot Open Loop and balance it with Fuel trims Long Term / short term are not beyond plus / minus 20%...

Oh how sweet it is !

The supplied taps on mine are not pressurized under boost. Therefore no check valve required. Has vacuum but no positive pressure I recall. I do use an Oil catch can and it does catch oil , maybe 2-3 oz over 4000 miles. Zero oil drawn into the intake breather line before throttle plate. Zero oil...

No to veer to far off topic, it happened fast once concrete work was done. About 30 days and a holiday delay… metal fabrication factory will not cut the material until concrete work is complete and has to cure a month. It was poured 6/8 building done 8/4 This is to help me at 61 years old...

Thank you guys.. Got finished yesterday… More to go Phase 2.

Installed pulley on the truck is 70 mm stamped on the pulley , and provided one was 75mm. Why I changed it, didn’t see much boost in the mountains of Colorado. Depending on elevation maybe 2-4 psi with the 75 mm pulley. I haven’t swapped it back, like I said I forgot and left it as it is...

Sorry for the late reply, busy week. My stock setup before heeders , Wideband performs better when pointing downwards “AEM” have recommended angle to stay within. I put it in the Pipe pre cat on left side and complied with the angles. To basicly prevent moister from pooling in the sensor...

Thanks for the update on the part from AUS. Unrelated to the swap, but my building finally framed yesterday. This will allow easier 8HP swap… in my 100. Hopefully finish shop, then follow your lead on swapping my 100 over to 8HP70 too

This is a stronger setup than and an open center differential for sure. I to avoid constant drag of spinning front axles and a driveshaft I went part time 4X4 with a front locker on my 100 series. I don’t live in an area needing full time 4 wheel drive. My 80 is a full time and would benefit...

Neighbor you say, Have to meet to break open an adult beverage or a coffee someday. Wide bank one bank now, narrow o2 on bank 1 and 2. When climate outside air is down I don’t hear “what I think is maybe spark knock” I mean right load right rpm I maybe hear it. But that can be too late when...

David310 Howdy, are you planning stock lower end engine with 7-8 PSI boost? Depending on your altitude “MSL” you are operating, 7-8 could he ok… down near sea level I wouldn’t plan that much. Ask Elate and year / version of 4.7 you have just to cover yourself. I am 6-7 psi now at 600 feet...

On your supercharger, that’s my picture I took of mine you posted, that I got from elate. 2UZ non VVTI 60 mm intercooler. That intake was complete either in that picture and Elate had to do and angle adapter on the end to mount my throttle plate to point it to my airbox. If you considering the...

Unfortunately, trans is getting some miles on it… getting a little soft 1-2 shift from start off… why I am planning 8HP70 … lower 1st and double OD .. I am trying to keep this trans alive and pull a small trailer shifting returns back to normal with the little extra load. Normal driving it’s...

Not to get to far off topic, I followed J1000 lead and did the supercharger on my 100 series , now 40k miles later still going. At 421,000 miles oil consumption is around 1 qt per 4000 miles and time to change it. Far as gauges I did a tempo removable solution and it has worked for 40k miles…...

Sounds doable…. The welding to the case would great to reinforce the area. Welding to the case, is that maybe like a sand casting, weldable by tig? My lack of knowledge here…
