More Hp L8T

[SSMatt]

Hello, I recently got a 25 ZR2 with the L8T and put a Procharger on it. It has more go, but I'm not as impressed as I thought I would be. I ordered some SW long tube headers on Friday, and they're a four-week turnaround. I was also looking into a cam swap, but I really didn't see any good info. Can anyone point me in the right direction?

Thanks in advance.

BonecrussherSS on the tube's might be able to help and there are 2 guys on the forum that are into HP. They should chime in.

@SSMatt you must have the same belief in horsepower that I do. Too much is almost enough.

That rig weighs 8500 lbs and sits large, you won't feel as much benefit from additional HP unless it gets +50-60HP and 80-100+ ft lbs of torque. Harder to do on a gasser!

That's why I did the procharger first. 50% power increase.

Hey there,
As a member here.. I do projects regarding new and old.
Done many LS projects as they are easy and reliable.. Tons of aftermarket parts available for the early projects.
So it appears that warranty is not an issue..
So first the L8T doesn't possess all the DFM and other restrictions . But it does possess Global B
Hardware configuration..
As you speak of the enhanced pro charge application, this would require ECM modification to properly tune. Along with TCM cooperation.. this alone is doable but with cost.
This mod alone is in excess of 18k from my biz.
To add The Stainless works is another mods 6k and tune. Many other mods are required ....Cam, heads..springs retainers ECT..
Pistons, rods, crank for improved lower strength . Applied turbo is probably your best lower cost option. This includes removal of factory set up .
GM doesn't make things easy..do to current laws.. Fords are more favorable for serious modification.
So to conclude save your money and drive it!
Unless you have around 80k to spare for 680 hps and 595 pound feet to gain.
Or I can sell ya a 572 c.i. for around 55k
Making 1050hp and 820 ft lbs

Did you dyno it before and after? If you're putting out 600 HP and can't feel it, your then it ain't working without the necessary tuning.

No, dyno, I didn't say you can't feel it I just said I wasn't very impressed.

I had to send the PCM to procharger for a "general tune" I had reached out to HP Tunners, and it's not supported with them yet.

To keep in op range it would be a waist and underdive pulleys wouldn't even give 80 hps and less than 50 pound feat. For a cost of around 12k . Not much bang for your buck.
Header wouldn't add much . Most loose power!
The whole thing is drivability!
