You know,. We could have had an intelligent conversation. Y'all could have proved me wrong. I did my research. And I know how Whipple ran boost safely. But none of y'all could tell me. Instead you backed me it a corner and threw hammers at me. "You're a dumbass" and "my truck did this or that" isn't a discussion, it's a dick measuring contest.

So congratulations y'all got bigger *****.
I'm out. Enjoy your circle jerk

Get off your high horse, you're the one who came in here spouting garbage and defending it then denying it altogether. I hate the spread of misinformation. OP boost will not kill your motor so don't fear it. Here in CO my stock fuel pump feeds my 1500 just fine. I put an AEM 340lph universal pump in my 3500 as the Napa replacement was not up to the task.

Perfect, I'm here in Colorado living at 8600 feet! Haha! Good to know. I didn't think 6 psi could kill it, especially because it's still under the 400 horsepower mark.

Hey y'all calm down this thread was about making more power with bolt ons, I wasn't looking for this honestly-laughable debate lol.
I'm still on the rocks due to the fact I will still need to update my fuel injectors to the MPFI, I'll need a 255 lph fuel pump, headers, regap my spark plugs, of course a cam, and hook that supercharger air filter into my current air box. But having 6 psi of boost with a shift kit would be a badass upgrade.
Guess we have pretty firm opinions on how to add power. Kek. Never in a thousand years would I have considered forced induction on a street drivin small block. But If it tickles your fancy, roll with it.

Sorry for trashing your thread

Timing and the right fuel is the key no matter what your dealing with plus the right spark plug too.

6psi should give you about an extra 100 . So at that elevation that would make a big difference..

We are runnin 38 psi on a stock bottom end 5.3 with twin 71mm in my buddy's car.

Why is that?
I've put over 280,000+ miles on a turbo LQ4. It's been a good one too. Towed all over the place with it and daily drove it for years with just regular maintenance.

That same turbo setup is on my 91 C1500 now with a 5.3. Already put 14,000 miles on it this year. Might hit the 300,000 mile mark on this turbo by the end of this year.

Dang that's badass! Im gonna get it tuned for 91/93 octane fuel of course. Timing will be set by my tuner, which I got a great reference from the owner of Wynjammer. Also, a 411 PCM swap is going to be done, too.

Awe hell. All this fighting. Y'all should have told me your at 8600ft. **** you need 5# just to compensate for elevation.
Hell yeah man boost away.

That's no kidding! That includes me trying to breathe My home is back in Texas at 400 feet elevation so there's a difference for sure.

My motor couldn't take boost. I had to roll the timing back to run 89octane.

Really, At sea level nobody boosts anything. At least not around here. Just #6 down here is 11# on OPs motor.

Plus I've seen the Dyno numbers on 6# of boost. I can do better with a cam and heads.
