Sledge's improvement was almost twice as large when you look at it honestly.

But didn't his car get a cam, headers, and CAI after his initial baseline.

I think you missed the point I was making. I was not comparing superchargers, but comparing dynos. The typical internet hp thinking would see Sledge's 615 number and Edlebrock's 580 number and think Sledge got very little with his motor work. Looking at the only thing that matters, gain on the same dyno, we know that he actually gained quite a bit. The numbers are not comparable between the two, after all, one reported over FIFTY more hp for a stock LT1 than the other did.

Edited to add: I hadn't noticed that Sledge's baseline was with a CAI, Exhaust, Ported TB and ported Intake Manifold. This means that the difference between the dynos is even bigger, since we know that these bolt-ons have been tested by others to add power to the LT1.

Sorry, I misread your post, thought you were trying to compare % differences in gain between SCers, so yes, I agree, dyno results cannot be compared. Even on the same dyno changes can occur on different days, just lash the car down differently, let alone input variables/weather. Anyhow, the real test is on the blacktop, but even there weather and track prep even on the same track can be different and effect results.

My car bone stock went 426hp, but it wasn't on Domin8's dyno. So next week we are going to run it baseline on his and see where we are. It's back to bone stock as well. So that will help show the true gains of this set up.

Mine will be on 91 as well. It's hard to find 93 around here, and I don't know that there is much to gain in those 2 extra octane? The weather will play a big part, and the M6 doesn't rob as much HP as the A8. I also can't shift as fast as the A8 lol.

Excellent! You will have some real data on the gains that you get from your project. Good luck!

I guess my question came across wrong. I understand the weather and tuner play a big role in what numbers are posted, but he was way off from the 650-700 guesstimated number and has more mods than I will. I started life as a mechanic and work in that industry now, so I fully understand the dyno pulls and that fact it's a tool. The mustang dyno also pulls from the number just because of the way it runs. That number is just a long way off, that was my only point. I'm not chasing a dyno number, my car is and will be a street car. I'm good with low 600's if that is what she turns.

That car was dyno'ed on a machine known to product low number.
(and thats totally ok, cause its the "gain" that matters, not the numbers)

Car went from 388 to like 615 or something.


ON CALI, junk junk junk junk 91 octane!

Thats saying something.

That's a good point on the gas they have. My pro-charger will be here towards the end of next week, so I'll know what I have shortly after. I'm looking to run a baseline Wednesday after work. This will be the same dyno that my car gets tuned on. So we will see where we are starting. since the pro charger is not far away we are probably going to start working on it towards the end of this week also.

Well.. this dyno wasn't as good to me on the number side. SAE 0.99, humidity 37%, 58 degrees outside. Made three fourth gear passes and the graphs laid on each other real close. 410hp and 421 ft lbs torque.

I would say that 410 is actually on the higher side of stock cars I have seen.
If not dead nuts on the money.

And I have dyno'ed a LOT of them.

That's good to hear! My very first dyno pull at 2,000 miles on the car came in 426hp. Dyno Jet dyno as well. Different time of year and day then. He was running SAE as well, I don't want non corrected numbers from STD lol. It sounds like my more recent one is more in line with normal.
