That's impressive for that weight. You got more cubes but I still think it'll spool just fine. What boost were you at? Hoping for 10psi on mine.

 

I've always wanted to do a rear-mounts setup and use the turbos as mufflers but always shy away from scavenging pumps, but they have so much potential for awesomeness.

 

whats the point of those welder mods? just make it more powerful?
The welds look like they are still flux core.
why not just get a better welder? my tig i bought almost 10 years ago was one of my best investments ive made, and you seem to build enough dumb ideas to justify it.

 

It seems like if you stay with the Turbo Werx pumps they are much more reliable. So between that and adding a check valve in the feed and return line, I shouldn't have to worry about all the oiling issues that people had early on.

The welder wasn't mine, it cost me $20-30 to turn a pretty lousy welder into something that is actually solid enough to do real exhaust and brackets with. Yes, turning the flux core from AC to DC makes it significantly more powerful since DC current has more energy than AC which only gives you the power every half cycle.

 

I'm not a fan of using them, I prefer gravity but Weldon makes a nice pump as well. I'm using the 9200-A currently but have used the turbowerx in the past.

 

I'm all for gravity over a pump, but no gravity on a rear mount lol. The Spartan was SUPER quiet on youtube so going to try it and see. I heard good things about Weldon also. It seems like the OEM STS pumps were the ones always crapping out....partially because STS was dumb and had you run a power resistor to limit the current the pump could pull.

 

just let the oil drain into a container and then dump the container back into the motor after every drive. then you dont need any of those unreliable and complicated pumps.

 

Why didn't I think of that?! I did look into a self-contained oiling system, which requires 2 pumps; and into COMP oil-less turbo's, which cost more than a turbo kit.

 

There was lots of dumb with the original STS kits, but with some improvements I can see it working. I agree I much prefer gravity but stuck with low mount turbos currently until I'm ready to ditch the luxuries of AC/PS, etc. I run the pumps at key on before start as well as after shutdown to ensure its all flushed out, not very long even 15 sec seemed to help.

 

That's the plan. I'm almost wondering if I can just have a large capacitor (like the 1 for the welder lol) in parallel with the pump so on key off itll run for an extra few seconds....cheapest turbo timer in existence.

 

why do you need two pumps for a self contained type setup? is the turbo too low for a gravity sump so you would still need a scavenge pump?
my friend ran a harbor freight water pump as a scavenge pump for a couple years a long time ago. he never had any issues with it, but it was a race car.

 

Should work

Have to factor in cooling for a street car as well, a small reservoir of oil is going to get hot quick. So by the time you add a cooler, pump, reservoir, etc you have a more complicated setup.

 

^This. Didn't want to have a reservoir, cooler, 2 pumps, sump, etc. etc. The LS is great because of the fitting just above the oil filter which acts as your 2nd "pump".

 

All the pipe lol. Got the intercooler too and LT1 radiator shroud. Looks like judy about everything I need to get started. Just have to cut out my driver side SFC first.

 

is that your driver seat ? in the top left corner

 

isn't it all about weight reduction nowadays????

 

better make 550hp LOL

 

 

No 550whp no care. Lol

 

I figure 10 psi should do 550whp without trying too hard given the healthy ws6 and slightly higher compression over an ls1. Cam will work nicely too.
