Note: This project is an open and blank canvas, suggestions welcome. If you have real technical knowledge or lessons learned, please post!


Supercharging project for a brand new 2019 Camaro (2019 because it's discounted and black because the front end of these model year cars leaves a little to be desired...) My intent is to push hard to 750 hp on the first build, and then ease up to 4 figures with upgrades.


car: 2019 lt1 1le with 2ss pkg and 30 miles on the clock. I drove it home and began the teardown.


If you want to jump in with a warranty comment, tuck it way down deep inside. Way down. I am the warranty.


Plans? open, but I am leaning toward a Whipple. i like the concept of efficiency! 1000 crank HP goal



Bottom end? looking at a reasonably priced home-built forged setup. Drop in pistons, rods, and rings are a possibility, but right now I am thinking fully forged crank, rods, pistons, balanced from the seller, and it will be at the stock cubic inches. I am also considering a compression ratio less than 10:1, but I would like to maintain squish features, flame front concepts for efficiency. If anyone has comments on whether the cylinders need a honing after those first 30 miles, please post! I am inclined to have the block fully inspected and dimensioned to identify potential problem areas.



Cam? please provide input! I will be seeking streetable boost cam that will meet my horsepower goals and my inclination is a lift less than .600. I have run the donkey cams , have seen the decreased life associated, and prefer to avoid. In fact, it will probably be a Comp custom grind. Oh, and I will be adding a camshaft with an increased fuel profile. 116 LSA? Duration 228/236? ICL? Forthcoming!



Porting? I'm unsure as to committing, as this has been a major project staller in the past as I can tend to procrastinate. If I port, I will be doing a simple job (casting edges, short side radius, etc....) and I will not be porting cylinders 7 and 8. Ill put in maybe an hour per cylinder. Short and sweet! I would prefer to avoid big price and big flow heads. I am a big fan of polishing the combustion chambers to reduce deposits and delay premature detonation due to buildup. This may be the only part I do, lol. A few cartridge wheels and a 15 min per, voila!



Fueling? How far will an lt4 in-tank fuel pump go? What is a better starting frame of mind if i intend to hit 4 figures?


Rocker arms? Stock will be shipped for a trunion upgrade, unless there is a smarter idea?



Headers? Is 1 7/8 enough? I am thinking purchasing headers that are coated first as a priority, and stainless as a secondary consideration. manufacturer and suggestions welcome!

I like the gutsy approach, hope you can pull this one off

There was a good point in the other thread you started, the wheel/tire combo you are planning to use. Unless this is an all-out drag racing build, I don't know of anything that can put down the amount of power you want in a RWD setup and still be usable on the street. Heck, even my measly 560 rwhp takes drag radials, no "normal" street tire can handle it. So what's the plan there?

[danf1000]

itll probably end up with a drag radial on it for those moments where I wanna pull from a dig. To clarify, I will probably limit the final to 850 wheel, or approx 1000 crank.


any thoughts on my approaches or insight on best methods/hardware?

Heads off, pressing toward a full forged build. my idea is to go fully forged with lt4 pistons, if they fit

Is there a recipe for lt4 pistons, lt1 crank, and forged rods out there? my question now is will lt4 pistons require balancing a lt1 crank. I prefer a stock fit piston that is quieter?

Also, I would like to get aftermarket forged rods. Are there drop-in rods for an lt4?


whats the solution for a fully forged lt1 with lt4 pistons?

The LT4 pistons are not invincible either, although admittedly much better than LT1 versions. If you’re pulling the pistons & rods, you’re much better off with either the GPI or Vengeance drop-in piston & rod combo. They will work right out of the box on your already-forged LT1 crank.

[danf1000]

both of those solutions do not offer selectable compression, but tsp does. id much rather not have to use meth, but a port injection setup that cools the pistons down sounds smart....

-20cc pistons are selectable with wiseco pistons!


thanks in advance!

I’m assuming you’ll just have to have those balanced as they are likely not drop-in. The Vengeance ones drop the compression a point if I’m not mistaken, without having to rebalance.

OK, all, having a tough time getting that upper bolt from the manifold/exhaust connection on the passenger side. oil filter is kinda in the way but it aint the deal killer. It's a closed in area between the firewall and the bell housing, oxygen sensor, etc... im thinking a shorty wrench would break it.



anybody got a suggestion?

[danf1000]

maybe a crows foot? attached to a long extension? Thanks in advance!
