2022 ZL1 Baseline Dyno

1sickzl1 · 01-23-2023, 01:06 AM

Over the weekend I took the car over to establish a somewhat baseline dyno so that I'd have some data once I add more modifications. I know the number isn't as important since we are interested in delta, however the numbers seemed rather low. Could this be attributed to shit 91 octane? See details below:

Dyno was performed on a DynoJet, SAE corrected w/ smoothing: 5. 2 pulls.

63 deg. Fahrenheit, 30 deg. Fahrenheit dew point, 35% humidity, 30.28 inHg, -55.6' DA, 164' elevation.

Vehicle info: ZL1 6 speed manual. 91 octane gasoline.

Mods: NO TUNE, Rotofab intake (non-Big Gulp), Soler TB (91 mm, eff.), ADM Coolant reservoir v2.

It really just depends on the dyno. I've seen anywhere from 520-580 in a stock car. I would just look at what is gained later with mods. 91 octane will pull more timing when heat soaked than 93 though.

YES It is quite possible 91 was a somewhat limiting. You would probably pick up 20 HP on good 93 assuming the tune was adjusted for it with more timimg. 550-560 would be what I would expect to see on 93 with torque around 550-560 as well.

Hard to say without seeing logs however it would not surprise me if you're losing some on 91 octane since these cars are sensitive to octane even on 93, but I wouldn't worry about it if you're getting ready to mod it, the delta is more important as long as you're using the same dyno when comparing numbers.

Really impossible to say. Some Dynos read generally higher in comparison to others across the board. What have other M6 ZL1s done on this dyno? Your numbers look like they fall within the standard range I’ve seen.

RobZL1 · 01-23-2023, 07:46 AM

Based on the shape of the curve, I'd say you've got timing being pulled or throttle being closed. Likely timing being pulled.

You are correct, a little low of other posted baselines... but i think it is inline if we agree on an 18% driveline loss. Like others have said... these cars done run their best on 91... and depending on your mileage, newer "tight" motors can dyno a little less.

Like you said, just a number. As you continue to mod, I would try to use the same dyno, so you get the best back to back comparisons.

Can i ask what shop you used?

As others have already mentioned, you would likely see 15-20whp or so on good 93 vs 91. Even then 93 isn't really enough octane to keep these engines off the knock sensors. GM sets the timing maps up very aggressive and uses the knock sensors to keep the engine alive. In many cases I pull timing from the stock calibration so there is no KR even on a stock car with 93.

I have had some bolt-on cars that would only take 17 degrees on 93 pump gas without triggering the knock sensors. However, on E50 the engine would take 25 degrees all day. And this is why I am an advocate for running E85 or a blend of in these cars.

So, my 104 oct. is comparable to E50 in terms of the advance it will take (does my final tune have 25 degrees?)

Ethanol is superior then race gas, not only for the octane but because of the cooling you get from ethanol.

Is the 104 octane leaded? Everything in this area over 100 octane is all leaded.

Silly goose, he can't see your posts. Probably best as he would argue with you that 104 race gas is superior to E85 anyway.

Oh right, i keep trying to answer his questions but forget he blocked me.

And yes your probably right....

Completely normal on 91. On 93 you would be closer to 550 and that’s where the majority fall.

arpad_m · 01-23-2023, 09:35 AM

^^^, you'd have 20 rwhp more using 93, plus it seems you have some timing pulled in the midrange where your max torque is made at a little lower rpm than expected (it should peak at around 3750 rpm). I'd also join the E85 choir, it's an amazing value for a little bit of cost (flex fuel kit) and perhaps inconvenience.
