I have a 2009 Silverado LTZ CC with a 6.2. I installed a Magnacharger TVS 1900 when the truck had 3000 miles on it. I wasn't happy with the stock supercharge performance-POWER IS ADDICTIVE. I installed smaller and smaller pulleys on the supercharger- down to 2.75" and larger pulleys on the crank. The boost pressure was over 14psi. The 6 rib belts kept breaking-about once a day if I really got on it, so I installed a 10 rib belt system from ATI and a ATI super damper. I also installed a Snow meth/water injection system to keep down the knock. Justin at Blackbear fine tuned the system and let me tell you- it will run!

But, and this is a big but, I know that if I would stay on the throttle hard for very long and often that this engine would not last a hour. You have to use common sense when you drive something set up like this. That not to say I don get on it, I do and more than you might think but I don't abuse the engine. You might find that hard to belive with 14 pounds of boost but you don't have to stomp on the throttle like a 16 year old everytime you take off. When I really want to accelerate fast I just roll into the throttle until I hear or feel the rear tires spinning and don't give it any more juice until it is ready or you just burn up the tires and the engine. When the rear end locks up solid about 45 mph you can get down on it and pull the full 14psi.

I have been driving with this set up for about 40,000 miles now and I have had to do nothing to the drivetrain at all except change oil and filters.

This engine runs as good as the day I put the supercharger on it. I feel it will run for a long long time.

I know one day under hard use something may give way but if it blew up tomorrow, I would not be sorry. This truck is a complete pleasure to drive with the power it has.

One thing that I found out though was to be very careful with a 4 wheel drive launch. It is absolutely brutal. I only did it once under full throttle and I am surprised with the violent acceleration that something wasnt totally torn up. The shade on my sunroof flew all the way back and my grage door opener on my sunvisor flew off and hit me in the head.

It was something that I would not do again- way to hard on the truck and engine.Just using rear wheel drive is like a fuse and limits the amount of power thru wheelspin that the drive train endures.

Just my thoughts on the subject. GM truck engines are very very tough!

I'm curious of the output my truck will have with the right cam and a TVS1900 on the stock bottom end. Since I don't have a warranty I will push it as close to the edge as I can

I can't speak for Louie730 but I have a stock bottom end and I believe that PDYoung does as well. I don't think that GM would sell Callaway conversions new on the lot if they didn't trust the bottom end. I think you'll be safe Chris, especially being 2WD. You will have to ease into it with that much power, which, unless you wind it up to 8000rpm, should save you from blowing the bottom out of the beast. As the Nike ad said about 20 years ago, Just Do It. If I'm at 540hp(at the crank I'm sure) then you should be around the same as I'm pretty much stock besides the supercharger, cai, larger injectors and exhaust. Your hp is already about the same as a stock 6.2, so you should run at or over where I am now.

I can't speak to the Edelbrock E-Force install on the 5.3 GM, but I can tell you after installing it on my 2007 Mustang GT, it was probably one of the easiest and most complete kits I ever installed, not to mention the instructions they included made it a breeze. About a year after I installed it and 14,000km's later, I ran into some lean code issues, but couldn't pin point it down. Edelbrock worked with me every step of the way analyzing data logs, fuel trims, etc., to try and nail down my problem (even though they didn't even have to answer the phone for me). In the end, between my trusted mechanic and the Edelbrock engineer, it was determined to be a faulty fuel pump driver module. The customer support from Edelbrock alone sold me as a customer for life.

Jon how much timing adv does your scan gauge show you? Right now I'm pulling 40+ degrees at WOT

Checked again this morning :driving: found that at cruising speed I'm 32 to 42 degrees, WOT drops to 22 and climbs a little from there, and like you on the wind down jumps to about 42 degrees. Just to make sure though, I may check again tonight. :thumbs:

      2019+ Brake failure, it's complicated

      By needafix · Posted

      I'm not sure if this should be a new topic, let me know if it's out of place. This my first post. Thanks 85077522 - AC Delco GM Genuine Parts Brake Master Cylinders. Anyone else had to replace this brake master cylinder yet. I didn't do any brake work, it looks like new parts and I've had the truck for about 4k miles, 119k total miles.  When it started to throw codes I did the calibrations with a bidirectional scanner and got the codes to clear but they came back so I did the routine; base bleed, automated bleed and final base bleed. All that with Bosch ES16-32N fluid (please look it up). That seemed to fix it but 100ish miles later it failed again so I ran the same process but with a pressure bleeder this time and got the same results, fixed for 100ish miles. The original fluid looked bad and I thought I got most of it out, it could've been the wrong fluid. The codes; P25A2, C05B0-00, C2A1B. I can get them to clear but not for long. The C05B0 indicates a leak in the front circuit (which is bone dry) so I'm thinking of doing the bleed process on that front again today and I don't know if that's taboo to just do the front but at this point it seems like it's worth the try anyway. The new master cylinder/module unit is supposed to get here today. But now I'm pretty much convinced this install is over my head. I've called several shops and some mobile guys that I know but this thing is like radio active material, scary wise. I did get 2 local shops say they should be able to do it, one says he has the SPS2 programing capability. And with the battery disconnected is there supposed to be pedal resistance, mine is to the floor, then if I pump it I can get some resistance. I had a panic stop prior to this issue which may have contributed from what I read. And on the first attempt to bleed and hydraulic test the scanner listed things to look for and one was any gaps between the pad and rotors which I did notice on the RF corner and I removed the outer pad (where the gap was) cleaned it and the hardware and didn't see a gap after that but will re-check it. I read that if pushing the caliper pistons back then you're supposed to open the bleeder so as to not push fluid backwards into the abs module or it will damage it. If that's true then that's also a possibility from the previous owner having the brakes changed before I got it. I'm using an XTool ip500 scanner. Any suggestions, questions and comments welcome.

      Next Friday will be my 6 week point from my right knee replacement.  The surgeon says it will be fine if I choose to drive after this checkup.  I know I could drive now but best to do as my surgeon (and my wife) tell me.  Richard compared being 62 to 72.  I remember when I was in my early 60's I was experiencing slow but regular decline in my mobility.  Thanks to good medical support,  i continued to fight the speed and spread of this decline. During my 60's I worked on non-surgical methods and just when I turned 70, my orthopedic surgeon recommended joint replacements.  In a little over a year, I had one shoulder and both knees replaced.  This hasn't been a terribly fun experience, but worth the discomfort as my future mobility health trajectory has reversed.  It is a treat to now be watching my mobility. balance and confidence steadily improve!
