My supercharged Suburban was hacked up by whoever worked on it last. It’s a miracle it even ran with all the issues I found. In this video, I fix everything, perform some much-needed maintenance and steal parts from my 1000 HP Turbo Trans Am to make this truck fast again.

That's what I wanted to ask too. Is it possible to mount an intercooler between the intake and the supercharger ?

[@organiccold]

@@RichardStefanits not in that one, as the blower mounts in the top directly in to the intake mainfold.

[@Beer_Dad1975]

@@organiccold I don't know much about supercharging, but it should be possible to mount a water jacket style intercooler between the manifold and the blower as I've seen a few such setups around - of course then it might not fit under the hood anymore, and no idea what kind of cost it'd be.

Nice work Alex, i never even thought about a fuel injector being misrouted! Good find and great job getting that old nanny moving again

[@jessicamerritt8233]

To be honest I feel like you would get lower intake temps with that factory air box and filter. The airbox pulls air from fender instead of hot engine bay

[@GIGABACHI]

It does. No rocket science there. He just wanted more show(blower whine) than go, that's all.

[@TwentytenS4B8]

Factory air box draws air from behind the grille so you're correct in that it taps into lower IAT's. There's a reason that the factory who spent millions of dollars on R and D placed it there. Positioning the air filter in the fender behind the fender liner yields similar results.

[@ShizawnSanders]

This. He basically made a HOT air intake which is no Bueno.

[@AB-80X]

@@ShizawnSanders What most fail to realize is that the most important thing is fuel temp. Yes hot air does make a difference, but it's small. Now hot fuel on the other hand, that really kills power. Aside from that, a bigger radiator as that would lower combustion chamber temps, which are just as bad as hot fuel temps.

[@LegitStreetCars]

I just bought an abandoned Lowrider for $1,000! Will it bounce? bit.ly/3cx8ppw

US government : Everyone should be allowed to own a large 8 cylinder gas guzzler, to zip around town in and petrol should be cheap. I bet if the US, got people to buy mid sized sedan's weighing half of these trucks, modern engines with 4 cylinders, it would make a heck of a lot more impact on the enviroment than us having to buy gokart sized cars with 3 cylinder, 1.0 engines or batteries... \Rant off

[@NickTheFelice]

As far as your brakes issue, I found that with my 99 silverado I've had for the last 11 years the brake fluid being flushed out and slapping new hoses on it really helped. I know I'm not carrying the bed weight of your truck but, I can light them up on dry ground with no boost (truck has 266,000 on it now). The brakes hold tough. In a previous video you mentioned 2wd trucks in the Midwest... I bought mine in the south to bring home. It's been in metro Detroit its whole life with me and only 2wd (bought with the Z82 towing package, same coolers you have on your suburban). She hauls every bit of her 8200 lb limit....and then some (sh). The winter time brought me some concerns so here's what works: Changed the rear end out for true trac locker. No one wheel race car problems, and it won't spin the tire on a patch of ice for 2 traffic light cycles and people behind you get super mad. Don't ask. Tires: dueler at revos by Bridgestone, bfgoodrich AT TAs. Both have been great. My Michelin set now is a solid OK ish. A few pound in the tail end never hurt, but I got lazy and quit doing it. Having a 2wd 1500 with no factory traction control has never got me stuck in a Michigan winter and I'm happy with it overall. Great for towing and also still usable year round. Feather the throttle when the snow fights but she will move nicely.

Alex, if you want something really cool to build, build a 90s-early 2000s Toyota 4Runner Tundra or Tacoma. You can get a supercharger for a dime a dozen for them, and make some REAL power. You’d get a lot of followers by doing so.

I went to the website for the digital service manual that you posted. I see that the cost is $12.99 for the manual that you used. I then looked up the manual for a 2004 GMC 2500HD Duramax and it was $24.99. I was surprised at the difference in cost, Do you know what they attribute this to? I came home with my 2004 Duramax. It was running poorly and had a Banks Six Gun controller on it. I pulled into the driveway and shut it down. I went back out the next day and it cranks, but will not start. I was hoping to find the troubleshooting on this in the online manuals. Do you know if this type of thing is covered in both manuals? Given the price difference, is there a major difference between the two manuals?
