What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Geotrash]

You'll end up returning them. I threw on a "great" set of leds maybe 2 years ago. They were definitely much brighter but only to about 15 feet infront of the truck. They lack distance. Huge no for me. Bought some ss3 fogs instead and havent looked back

I had a similar experience with a set from "Headlight Experts". Paid a premium to get what I thought was the best and they were great for low beam and worthless for high beam, no matter how I adjusted them. Lasted less than 2 years, to boot. Went back to regular long life bulbs and haven't looked back.

This is exactly why I just can’t commit to the LED headlights.

this is the one you want, bought mine in 2019, price has gone up about $30 and they take 6-8 weeks or longer to build and ship.

250 Amp high output alternator for GM Truck 05-13

Shop Mechman 250 Amp high output alternator for GM Truck 05-13 8302250, best prices, fast ship time & top notch customer service! @ Mechman Alternators

www.mechman.com

or you could go with a GM GENUINE 84143539
gm started making them like the mechman design with pressed diodes
it's actually for a k2xx 2500 but it will fit and work and is about $100 less than the mechman and is only 30amp's less

More Information for GM GENUINE 84143539

Thanks pal!
Does your MechMan run a smaller than stock pulley?

I thought I remember hearing that the k2xx were swappable, but the highest I saw was 170amp.

standard pulley on this one, I didn't buy the higher amp for the same reason I rev this thing way past 5k all day lol.

 

[Doubeleive]

the 2021+ ppv's have a 250amp alternator which should fit also but you would have to swap the pulley over because those are a clutch pulley

How much more energy from the engine does a larger alternator pull, like that 250amp over a 140amp?

Finally got the new Remy starter installed in the 2007. Easy job with the fender liner out. I got lucky and was able to remove the heat shroud on the exhaust manifold without breaking any bolts. One was already broken previously, but the others came out with no trouble. Luckyyyy! As I look at this photo now though, I realize I need to install the heat shield on top of the solenoid.

Crap that reminds me I have a rebuild kit for my starter on my 02 that I was going to do this summer. Times runnin out.

I think my starter is rapidly going bad. I have new dual batteries and a brand new alternator. It acts like there's a dead spot, like the starter starts out fast but the dogs like there's no power to it. Mine is original... I know I should've replaced it when I replaced the engine.

I found factory one on summit, but the fitment says for Camaro with 6.2 and G8 with 6.0 or 6.2. Why would it not fit my 6.2? Here's a picture with the P/N. I'm thinking this one will work

What is that black vertical pipe or hose just to the right of the starter in this pic? Also, what's the sensor to the right of that?

 

[Doubeleive]

probably not much, were talking drag coefficient which is complicated math like what is X when y=2.0 and what is x when y=2.00000000000001
math that school said I needed to know but has no practical application in life unless I intended to become a engineer.

dipstick and knock sensor

Dipstick tube and knock sensor beside that.

Check to make sure that the connector for the small wire is the same on your starter and this one. They went from a threaded post to a plastic connector around 2009-2010.

You still have to go underneath too? Or did it all through there? Just bolts in right, no shimming like on the older GM engines? That's how long it has been since I did one.

Do you have a pic of the starter removed showing that area of the block? I read somewhere there is a seal in the block behind the starter that could leak oil.

If under the same electrical load- they'll put about the same load on the engine. The difference lies within the alternator's efficiency and friction factors (bearings, weight of armature, etc.). If all is equal and your truck has 30 amps of total load when running (fuel pump, lights, A/C blower, etc.), then the 250A alternator will not induce any more drag on the engine than the 140A. They won't be equal, though. Actually, if the 250A is more efficient at operating speed, then it could induce less load on the engine.

About 1 horsepower every 25 amps at full output.

wheres @iamdub and his electrical gang shoutout

its not that complicated.
amps x volts = watts
150amps x 12v= 1800w

1800w/746 (1hp=746w)= 2.4hp
