Dyno this Friday, care to take a guess? Results will be posted Friday afternoon! OK, so after attempting to deal with all sorts of issues I've had with my car since its purchase in August of last year, it has ended up in its current state, listed below:
2002 Z28 Light Pewter Metallic M6
- Ported Patriot LS6 style heads (243 castings)
- 224/228 .581/.588 113LSA Comp Cam
- SLP Lid and Cold Air Induction
- Underdrive Pulley
- Ported and Polished Throttle Body
- Pacesetter Long Tube Headers
- Pacesetter Off-road Y-pipe
- Magnaflow Catback
- 3.5" Aluminum Driveshaft
- Moser 12-bolt with 4.11 gears
- BMR Adjustable Torque Arm
- BMR Subframe Connectors
- BMR Driveshaft Safety Loop
- Spohn Strut Tower Brace
- Spec Stage 2 Clutch w/ new slave - new master and drill mod going in Friday with the tune
Before the 12-bolt, 4.11s, 3.5" Driveshaft, and the ORY (previously had a catted-Y), I had the car dynoed and it made 405 rwhp and 365 rwtq, which seemed a bit low. A friend of mine asked to look at the tune a few weeks later and according to him (and because of a long string of events I'd rather not go into), the car is supposedly running a stockish tune right now with a few driveability adjustments made below 2000 RPM.
We always knew/thought the car wasn't running as strong as it should be for even a somewhat mild H/C car, but hearing this and having some people on HPTuners look at the tune convinced me that I should get it re-tuned on a dyno at a respectable shop just to be safe, even if it doesn't gain anything and is already tuned how it should be. I just need to know for sure that the tune is correct before I start throwing any more mods/money into it.
This Friday it goes in and I will be posting the results Friday afternoon when I get out of work. Just curious to see if anyone wants to give a shot at guessing what it might make, keeping in mind the 12-bolt and heavy driveshaft. I'm not expecting anything too crazy, but hoping to see a bit of an improvement even though the previous numbers were before the 12-bolt and driveshaft, but after the ORY.

Do not know. I will be awaiting your results as I have a similar setup that I want to dyno some time in the next two weeks.
98 TA
M6
SLP lid
P/P TB
LS6 intake manifold
Patriot ported LS6 heads (2.00”/1.55” & 64cc)
Cometic .045” gaskets
226/230 .57x/.58x 111+2 (224/228 .581/.588 110 nominal)
UD pulley
QTP 1-3/4” headers
Dual exhaust
Stock clutch, driveshaft, and rear differential
Bla, bla, bla
It is too bad we cannot dyno on the same machine. I always look at these dyno numbers w/ skepticism. Assuming your cam’s actual durations are similar to mine, your cam should carry longer and produce higher peak hp. That will be offset by your heavy *** and driveshaft. I really do not expect my exhaust to gain me much over your setup as we simply are not making that much power. 98’s tend to produce less power than 02’s for some reason, so that is another factor in your favor. What brand dyno will yours be done on?
Regardless, just for fun, I will wager you an imaginary apple pie that I will dyno higher in torque and HP than you; corrected numbers.

My friend installed 9inch 3.73 Gears with 3.5 Driveshaft from EPP
he made 431rwhp with 10bolt and stock Shaft he made 445rwhp
And the 9inch weigh more than 12bolt.

BSF - I'll take that wager since it's an imaginary apple pie!
Venom - I may throw a cutout on in the future, but not for this tune. I hear the Magnaflows flow very well, anyways, so I'm not too worried about it yet. Perhaps soon.
PewterY2KZ28 - Remember, you have a G5X3, which is a good amount larger in duration and lift, and should definitlely put out much higher peak numbers than my wussy little 224/228, haha.
To give everyone an idea about the rearend and driveshaft loss, I weighed my car before the 12-bolt, driveshaft, and adjustable torque arm, and it weighed 3,465. After installing the 12-bolt, driveshaft, and adjustable torque arm, it weighed in at 3,530! 65lbs from those three mods! I know this doesn't directly affect dyno numbers, but it gives you an idea of how heavy the driveshaft and 12-bolt internals are that that power needs to run through.
I am praying for some of the numbers I've seen thrown out in this thread, but to be honest, after all of the issues and past numbers I've seen with the car, I'll be EXTREMELY happy if I hit 420/390 or more (like you'll probably hear me freaking out screaming like a little girl from wherever you are at the time), but I am expecting more in the 410/380 range, give or take a few. I'll be upset if I don't at least hit those numbers, but I can't count on anything. And by "upset" I mean it will be time for a much bigger cam and eventually decent heads.
Keep them coming!

I am dyno-ing Monday morning. I forgot to ask if it is a Mustang or Dyno Jet. As long as I do not dyno (corrected) below 380hp or 365lbft on a Mustang or 405hp or 390lbft on a Dyno Jet, I will not be concerned. It sounds like you will not be happy if you do not see better results.

bsf - yeah, I just want to see some decent improvement. The car felt like it picked up a little bit with the ORY, but that might just have been the way better sound getting to my head. If I did 405/365, then installed the 12-bolt and driveshaft, I probably lost a good 10-15 from that, so I see myself in the 39X rwhp range, but then I installed the ORY which might have gained anywhere from 0-15 rwhp, so I am hoping that before the tune I will be around 400 (asking them for a baseline before any tuning).
Best case scenario, I'm hoping that 1) the ORY cancelled out the loss from the drivetrain mods and 2) the kid who checked the tune and told me it was bad in the first place was right and the car was in desperate need of a tune for the heads/cam, meaning I will gain a bunch from the tune, but it's all speculation until Friday.
There's every chance that the car is tuned to perfection right now and I might come out with less than or just barely over 400 rwhp, which would suck, but at least I would know it's not the tune. Some cars make crap power and some make awesome power with the same exact mods. I would probably be fine with anything in the 41X/38X range, and VERY happy with anything in the 42X/39X range, like previously stated.
ALSO, I know that dyno numbers are just that, and it's the track numbers that really count for me, but who doesn't like to see good dyno numbers?

Regarding the type of dyno and varying dyno numbers, it's nice because my buddy has an 02 Z28 just like mine (cam only, though), dynos at the same place as me, makes comparable power, and I know what his numbers at the dyno AND the track are.
Therefore, I can compare our dyno/track numbers and get an idea of how we compare. This helps us judge how well the cars are set up and how well we're driving them. For example, if we are making pretty much the same power and weigh almost the same, but one of us is running, say, an 11.8 at 118 to the other person's, say, 12.3 @ 115, someone needs to work on their driving, hahaha.
