LS3 - Is 550whp all motor feasible?

[xc_SS/RS]

Acammer, could you take some screenshots of those tables you mentioned? I'm curious if I've changed mine or not and if they'll help when I eventually make it back to the track. Don't have my laptop in front of me at the moment to check my tune

Well all in all Andrew, you still have a pretty nice car that sounds good. I'm sure it will all come around this season

No problem. This is what it looked like untouched. I did give some consideration to what you could do with this table as a launch control - but I think the problem is that the ETC returns to WOT too slowly in my experience. Unfortunately, I don't have any logs to show what this looks like - but it felt like a half second ramp once I started the clutch release. Not aggressive enough on sticky tires, at least not from 5000rpm.

Thanks Chris - it's gonna put in some better times this year for sure.

You guys really got me thinking about that bog - I was rewatching all my passes from that day and on this one you can really hear the throttle opening against the clutch release. Definitely was hurting the performance!

Thanks for the screenshot! I see what this does now, not sure it'll help me right away but still good to know about it. I want to go sub 2.0 for a 60ft before I think about stickier tires lol

Lol maybe at the crank!

What is an ITB?

I believe ITB refers to Individual Throttle Body.

As for the original question on this thread, I'm excited that we very soon will have a package from GPI to share with the public that will make a 550whp "bolt on, stock bottom end" heads/cam package a reality.

Since 2018 500-550whp out of an L99/LS3 is very common to do and achieve. Been thankful for a good amount of people on this page to let me be a small part in their build.
Here's a list that I have been prettying much helping people with

OEM CNC Ported heads (milled) - Aftermarket for better results due to valve angle
.040" Head gasket
Short Travel Lifters (Optional)
Cam spec'd for the build (Any good cam)
2" Headers (Optional)
E85 or higher octane fuel
Correct plugs
Measure your push rods (Highly recommended)
Intake Manifold upgrade (High Ram or CDI) Port matched
102 TB/Accufab 4500
Correct Springs for the build (Single beehives or duals)
Ti intake Valves (LS9) (Optional)

From auto cars to stick cars on average we are seeing 530-560whp depending how wild you'd to go.

I should add/clarify, this 550+whp package is a combination that will not require a high-ram or other short runner intake that is going to require cutting up your hood and cowl. Nor will it require an exotic valve-train or super high stall converter (and gearing for the stick guys) to appropriately support the rpm range those short runner intakes need to live at to deliver their best. Nor does it require modification to the bottom end to generate sufficient compression for the package camshaft - no fly cutting.

If you're up for getting more wild and want to do a high ram, valvetrain and drivetrain to support the rpm shift in the power, and fly-cutting to bring up the compression, then 600+ to the tires from your NA SBE LS3 is very much a possibility. Like 62nalide said, aftermarket manufacturers continue to push the envelope on what's possible on this platform, and those numbers are very much attainable. It requires a well thought out combination, but absolutely is not "rare" this day in age.

Our new combination aims to take the "well thought out" piece of the puzzle out of the equation, offering a one stop option for consumers looking for the complete package they can order and bolt-on that sort of power without researching and independently sourcing all of those important components. It also aims to offer a very streetable, non invasive (no high ram/short runner baggage) option. For guys that want to chase 600 at the wheels on motor, we'll have a short runner option for that as well.
