Went out took it easy left at 3/4 pounds ramped 13 highest boost was 15 as it spiked and leveled off at 13 pounds same exact tune up i have on the street nothing changed - i let off after the 1/8th well you can see by my mph
but first time at track first time down the strip on this combo only got to run it once.
2 step seemed too low needa turn it up a little next time around not bad for 13#s got another 13 pounds to go on settings

Cost example: I just bought a 2005 L33, 5.3L, with 799 heads on it. This will be a street cruiser, for my 55.
This is an all alum, 10:1 engine.
It's also built in a cast iron version, and will likely cost less. I pd $1950.00 delivered. 111K on the clock.
LOTS of 5.3's around here, for $500 a pop. Load one in the barrel, and pull the trigger.
LOTS of cheap offshore turbos, for less than a grand.
My choice for budget build, is stock truck exh manifolds, and the stock truck intake.

The sloppy stuff works!

The sloppy stuff definitely works. I like the information he provides. I didn’t use his combo but i do know they work.

I did. It's "out west", and having more work done on it. Not sure if we'll see any more of it.

Its getting some attention. Had a GN1 IC put on, and some mods made to a 4"RJC single shot exhaust so it would fit. Got an e85 sensor waiting to go on. Car is torn down for paint and body right now. Wish I had some pix of the exhaust, shop that modified it frkm RJC did a beautiful job. If youre on FB, search for "Ultimate Performace" they have a video of it, unfortunately background noise isnt the car idling

A '55?

Put in a 6.0 w/ LSA in my dads '57 with a 4l80, only using a 6 rib pulley, it startdd slipping at 9.5#'s of boost at 3500 and was down to 7 by 5500, did 502whp. Swapped the pulley for a griptec, hopeful for 550-575. All stock 275k mile engine, had the heads looked at, and put in a BTR stage 2 PDS cam

Yep... Back to the cruiser street crowd. Getting too old to constantly work on my car.
This one, I put gas in it, and go.
