CTS-V LS6 light mods, custom tune. Dyno results

[GroverDill]

I know it's not a 5liter but this is the only part of SN I post in and hey it is a pushrod motor!


I am thinking these numbers are too high, but atleast the graph shows the A/F right in the LS6 sweet spot. Mods are exhaust, intake tube, HP tuner custom tune.

Fun daily driver even if these numbers are inflated. Anyhow just thought I would post it.

auto or 6spd?

those numbers really arnt that far off from what the later LS1's were doing.

 

[GroverDill]

All cts-v's are 6 speeds. I have never seen a 385rwhp LS1 with the same short mod list.

I would trade my 5.0 and left nut for that caddy!!


Those #'s seem "rite on" to me.

Aaaah my old disagreeing friend....there is more to a car than all out speed. The Caddi will never have the character and style of a Mustang GT no matter how much faster or comfy it is. Although i like the Caddi, you have to admit they are a bit of a middle aged golfer's car.

No worries guys the GT is finally nearing completion, lord knows it has takennearly 3 years to get even close to done. The V and GT both share my garage, as for the middle age thing, well I do have 2 kids and the older is about to start drivers ed!

The new ones have 550hp. I like golf!

numbers do sound very strong, my buddy yesterday put down 320/320 with a 02 ss maro, 6 speed car with headers and thats it, well an intake but thats all, oh yeah and a 11.0a/f lol my other buddies car put down 295/325 auto car with only a volant intake and a cat back and headers.

 

[GroverDill]

This is a LS6 rated 400 dead balls stock, I think LS1's are rated 350 hp max.

 

[Mr. Rustypwnz]

oh I know, Ive known ls6's to put down almost 470rwhp with heads and cam and tune, they seen right to me, Im a big fan of the ls series engines!!! just wish ford would do a 6 ish liter pushrod engine..

 

[LaserSVT]

Or better yet, a 6ish liter 4 cam
I love the sound of my engine at WOT! With another 100+ cubes it would sound so nice!

 

[stykthyn]

my camaro was 340 with a whisper lid, headers, and catback, and underdrives.
I never got it dynoed after the heads were ported and the new cam was installed
I bet it would have homed in on the 380-400 mark with a good tune

I use Dynojet software almost every day and have yet to figure out a way to fudge numbers other than changing tire pressure or gear choice, and even then it's not by much. Oh, and people need to learn how to print dyno sheets. I heart ls1s.
