Yes sir. 90% of the welds here were done with a Norther Tool flux core that had a bad voltage control system for the spool, so wire speed was whtatever it felt like being. Then a few days ago, it finally quit all together and I bought a better Lincoln flux core, and it works great. If you give me a good welder I can make nice welds, I have about 1,600 hours of welding experience.

In this pic, welds on left are old welder, weld on right is new welder.

If you're having trouble scaling down the oil flow, you could also try this little pump:

Are you using the giant pump to feed the turbo? Or to scavenge it?

I posted links to two specific FETs which would work. One was a chassis-mount style with screw terminals, the other was a through-hole part. Selection between the two is up to the user, based on how you want to wire it.

Not sure if this link will take you to the correct post, but it's post #38 in this thread: Fuel Pump Voltage Drop vs Pressure 1999

That's a scavenge pump. Main oil pump and gravity feed the turbo, but it's too low to gravity drain back to the pan.

I really wanted to make little oil sumps that attach to the oil drain flange on turbos. Then if a little oil did make it past a pressure check valve in the feed line it would have a place to go.

Here's what f-body guys like to use on the oil feed. Takes a third a pound of pressure to pop.

Recognizing that I'm bumping a relatively old post in the thread...

There's nothing inherently wrong with gear-type oil pumps. They were used on every single Volkswagen & Porsche engine from the 1930s through the late 1970s (a design noted for its uncanny durability), and were a standard feature of many other OEM designs as well.



Obviously, the need to fully seal the driveshaft of the pump against leakage is absent from engine-driven pumps, but is present in external motor-driven pumps of all designs (including georotor pumps) save for diaphragm pumps.

Georotor pumps are used on modern engines mostly for reasons of cost and packaging size. As they can be fitted coaxially with the crankshaft, they occupy less space, and require less complex machining to produce. These criteria are wholly economic in nature, and have nothing at all to do with either reliability or ease of leak-proofing.

My post there was in reference to the noise of a gear driven oil pump, they are loud as hell. On an engine driven oil pump you wouldn't much notice the noise, especially considering all the other 1930's tech powering the pump.

You saw the video of it running, compared to a diaphragm pump?

Thanks! I think it's awesome power for the budget. Hell plenty of people not making this much power with any budget.

I made some changes to the fuel system, so this is only 80% duty cycle in the primaries. Will turn up the boost tomorrow.

can you please do a pull in 5th from 2k?
I know it's hard, but surely there's gotta be a road somewhere in your state to do this.
you're making great power, I bet it's a monster, but I care more about the shape of the curve than peak numbers

I know. This isn't a final plot, just a plot for tuning as I go. Thought I'd share. When it's at final boost with this fuel setup, I'll do that. For you.

I've been making short pulls for now because it's stupid loud, waiting on Magnaflow muffler and cat to arrive. And other stuff I ordered.

Gotcha, makes sense.
As for afr, e85 can still be kept at 12 unlike pump where you'd want to fatten it up with serious boost.

looks like it dips quite a bit past 7, lean it back out, you'll gain more IDC and pick up power.

that power should be good for 130mph trap speeds, and put a hurting on most street cars that are not tx2k cars
