Supercharged Tahoe TBSS

[NORCAL SS]

Did someone say meth????

I'm curious how much difference will make with your iats

 

[sumo]

That looks purdy. I haven't looked into meth setup. Is this used on top of pump gas or is it strictly meth? How much does refueling work?

 

[NORCAL SS]

Only sprays when boost. uses the windshield tank

Need to bump the fuel trims up a tiny bit. Other than that, she's running damn fine for a everyday family ride

Fell in love. Lol.

But I need my washer tank for salt covered windshield on the winter lol

 

[NORCAL SS]

Sorry to hear that lol.

Lol are you? Seriously, I think I would start with stronger internals and trans upgrades before upping the the boost

 

[NORCAL SS]

Not really. Torque management key on trans. My tbss was making 452 all motor and it lastest for a few months on the 100 shot on top of that.

I think you will get more power hungry... we all do. cam/heads

Haven't tallied the numbers but just the cost of parts because I did all the labor myself.
No oil pump upgrade needed, injectors that come with supercharger is enough to support 7-10 psi. Maybe more but I was told may need to switch to methonal to achieve more



Rear o2 are disabled I put the wb in the driver side rear o2 as cyc 5 and 7 seem to be the most problematic and fail. Moutning to wb here I can monitor if that side starts running lean.
I plan on using the pass rear o2 and adding another wb for that side

So your wideband is mounted behind the cat? Seems pretty accurate to me. Looking at the same column mount and w/b gauge.

Cats on these headers are small. It's recommend to be a bit up steam but I'm happy where it is ATM

Gorgeous build and I commend you performing all of the work yourself. Definitely an inspiration

Its definitely a satisfying feeling. Plus even better knowing I didn't need have to spend money for someone else to put it on. If there's a problem, I will more
Likely know how to deal with it because I put it together

Back on my build. Bought a 3.0 pulley but before I install that, I decided to upgrade my transmission. I'm having a level 4 Gearstar transmission built for me with the new sonex smart drum. Bought a Yank 2800 stall Sc series torque converter.
Both units built to order. Got conformation my TC was drop shipped to GS where they are going to install and dyno them together before they send it to me.
Uninstalled my PML deep trans pan and sent it to GS to install to my trans.
Ordered a Circle D aluminum flex plate and revived it today.
Went and bought various comports to replace while trans is going to be out, oil pan gasket, rear main seal plate assembly, motor mounts, transfer case gaskets, seals.

Do it. Do it now

Good to see you're back at it. You have the 4l80 trans, right? Also, I didn't see you doing a cam. Any plans on doing one?

Every time I think about mounting a S/C that anemic 5.3 gets in the way. For a couple grand more 6.0-6.2-6.3

Pulley down on a 5.3 and you will have more power than your trans can handle.

I'm curious if that fancy flexplate is going behind a 4l80 as well. Looks stronger than the cranks in our engines lol.

Got antsy looking at my 3.0 pulley. I decided to install it. New trans just got done being built and is on its way. Did a quick off the line pull. Gauge peaked at 12 psi.

Not anytime soon. After trans I'm going to replace front struts, upper control arms, upgrade the sway bars maybe Larger brakes and rotors.

I didn't do a 4l80. Too much needed to convert. I ordered a level 4 Gear Star 4l65E built up to handle 700hp and had them install the new Sonex Smartdrum that just came out not long ago. The smart drum is a badass piece of technology someone came up with. The 4l65e had newer and updated parts than the 60 and it's a direct bolt on no conversions needed.
