Dynamometer Results & Comparisons - Dyno results from LTs, ORY, and catback..along with some NOS 5177 kit #'s

The car baselined at 321.27rwhp 331.68rwtq on 6/25/05. Since then I have added Pacesetter ceramic coated longtubes, TSP ory pipe, a Hooker catback, and some TR6 plugs for the juice. I am honestly a bit dissapointed in the new numbers, was expecting at least 340ish rwhp, but oh well.

Car is still on stock tune, pretty much the same conditions as the 1st runs, and it was the same dyno.
336.80rwhp 349.43rwtq
So I gained 15.1rwhp and 17.75rwtq :huh: :bs: :ripped:

Now here is what I WAS impressed with. I did one run with the juice, it is a NOS 5177 kit jetted for a 125 shot.
438rwhp 504.57rwtq :D

That made me VERY happy. I gained 101.2rwhp and 155.14rwtq :hail: Gotta love the juice!!!

yeah get it tuned and the N/A numbers should come up a little more
Freaking 01 and 02 cars my 2000 with LT's catback other bolt ons only made 323RWHP and 329TQ, running lean though, still good baseline

Good #'s :drive:

you will gain as much as 15rwhp more on motor with a good tune. tis very nessasary!

this is why. all cars, modded heavily or even completely stock, can benefit from a tune. some people dont believe that but its true. get a tune and your numbers will be much better N/A.

All you basically did was add headers and you are unhappy with 15rwhp? How much hp should headers add again? :)

I have tuned a few cars with similar mods and they did around 342HP & 350TQ N/A.

I have the 5177 Dry kit on my car too. When I just had LT, Lid and Catback, I made ok/good dyno numbers with the N20 but I went way lean. Did you get a wide band on it to see where the A/F is at? If your over 13.0 (N20)A/F, your motor won't last long if you spray a lot.

You want 11.5-11.9 A/F for N20.

Yeah the 05177 didn't work on my car either (15 - 1) so we richen it up using the base tune

No, I went from TOTALLY STOCK exhaust to a full aftermarket setup, longtubes, ORY, and a good flowing catback.

Yeah, the wideband was hooked up. On the spray it was about 11.9 at 6k, the stupid graph I have shows speed instead of rpms :bang:

N/A it wasn't too bad really, about 12.6 at 6k. My A/F is actually better and smoother than when it was stock :)

All ya would have to do is ask me and I'll E'mail ya the graph with RPMs instead of speed.... :D The way we were rushin around that day, we are lucky I even remembered to print anything! :D

Let me know if you want us to tune it, we'll hook ya up. :)

I also gained 15whp w/mods in sig. but after the tuning I gained a total of 32whp and 23wtq, that's a gain of 17whp for the tuning itself. Get it tuned and you'll see the "real" numbers.

See!! YOU NEED A TUNE!! :D

Well if you aren't convinced already, let me throw my thoughts in..........Get A Tune. :)

how much overall could i gain from my 224 cam/headers ory/cutout was 316/341 before those, im gettin one in a little over a week and im anxious

SAE or STD #'s?

SAE corrected #s :)

I know I need a tune for the full potential, but I was expecting more of an increase even on the stock tune. But what matters is the final #'s WITH a tune....those will be here in time......
