I have an interesting contribution to this thread.
A few months ago, we flashed a Term2 tune on a club member's 2009 LNF, fully bolted, 91 octane.
He went to a dyno day today. Mustang dyno. Car makes a stupid 360whp/368wtq.
Bullshit, right? That's what I thought. When I texted Term, he thought BS as well. After all, that's the equivalent of like 400whp on a dynojet. Yep, happy dyno for sure.

But wait.

This morning I pulled the stock tune from another club member's 2008 LNF. He's bolted on 91 octane as well. He will get his T2 tune flashed in 2 weeks. I told him about the dyno day and how it might be nice for him to have his stock numbers as a base line.

So he went over and made...224whp/275wtq. Same dyno. Same day. Same Weather Correction Factor (WCF).

Stock LNF's should be within ~5 whp. That means a gain of 136whp. On pump gas.

Sure the dyno probably reads a little high. 224 on a Mustang dyno is about 250 on a DynoJet. That's definitely high. But the differential is the differential!?

Nobody? A 400whp stock turbo 91 octane unicorn?

Well this is what I said

If you were on e85 with your current numbers, like every other lnf cobalt owner on e47/e85 (+/-350whp/400wtq), you should walk that evo. The fact he beats you by three cars is a huge testimony to the ridiculously high numbers - for whatever reason. You don't have a unicorn cobalt. I was being sarcastic with my e47 comment above. Long story short, go race an lnf on e85 making your numbers and report back lol

I hear ya. Problem is that we don't have any stock Cobalts on e in the state. First thing everyone does is intake, down pipe, T2 tune. Ethanol typically comes after that. We could of course measure his car up to another T2 tuned LNF.

FWIW Elmers car pulls about as hard as yours did on stock turbo and E-85. Yours made more peak torque due to 2-3psi higher boost at 3500 or so so yours hit a little harder down low but the top end pull is similar when I look at the logs.

That's impressive. That setup of mine dynoed at 359whp so I guess he's right around there. I've kinda forgotten what my E85 K04 setup felt like. You get spoiled quickly

When you post your dyno chart and chris Zelinsky and James start talking **** to eachother on it

That whole post makes me want to quit the "gang". It's really not a group of adult cobalt enthusiasts. Guys like that who commented affirm my belief in why cobalts get no respect because of how most of those guys react.

Those two can go jump off a bridge. The world would be a better place.

Another note I just sent Adrian (Colodude18) an E-85 tune for that 08 that did the stock tune dyno run on the Mustang dyno. Hopefully he will get to run it on that same dyno with the new tune. 223 whp stock let us see what it makes tuned on E-85. Apparently every car I tune dynos on happy dynos I guess 😂😂😂.

Terminator2

268 whp GMS1 on the same dyno as the OP which is on the low normal end for dynojet numbers on GMS1 car (seen as high as 283 whp on a dynojet) so it seems to not read as high as everyone seems to think.

It also would depend on elevation level right? Like down here in Florida the oxygen is more dense so we're prone to making more power?

Those adjustments are made in the calculated power.

Those numbers are whack. ive seen two LNF's on a dynojet and then both went on a mustang next weekend. 294dj--->251md 329dj---->286md

well were right at sea level here.

^^this. The Weather Correction Factor adjusts the numbers for temperature, humidity and barometric pressure. That's why the numbers "with WCF" I posted are so much higher; we're at 5,400 feet altitude, meaning the car makes less power here than at sea level. That's also how we can get away with running full E85 on stock turbo without any fueling mods

I will make sure he dynoes at the same place afterwards. We'll have 5280Cobalts pitch in on the dyno run if we have to

yep we're at sea level here
