We did do a few pulls reading a/f. Its running really lean down low and gradually gets richer with rpm. The direct injection can run leaner then standard fuel injection but I was still surprised to see ~14:1 at full boost

I'm all for having a drag race with cobalts in various "stages" of tune at the track.
At 75 miles, i'm confident our engine is 95% broken in. Brand new engines built here get broken in on the dyno, tuned and are ready to go.
It was great meeting Frank, and i'll agree his stage 2 sounded better. I think once the TC is "opened up" it will have a nice sound to it. Supercharger whine is tough to beat though

Good people there. People who really want to get their hands dirty with an SS/T.
They told some of the things they've got planned for the SS/T, but they swore me to secrecy or else!

Yeah, SS/T put down good numbers (especially in the torque dept.).
But I'm happy that my Stage 2 SC made 227whp, within 10whp of the SS/T (even though I saw AND posted a pic of the monitor which showed 229.5whp!).

Dyno Vid Now On Streetfire
For those of you who want to see the vid but not download it, I set it up on Streetfire.net:
(NOTE: I just downloaded it, so Streetfire might still be encoding the vid ...)

The perfect comparo would have been to see a 100% bone stock SC, a Stage 2 + 0 SC, and a completely stock SS/T.
Guess 2 out of 3 ain't bad ...

we want to get all 3 chris. we will still put your car on the dyno if you want, we just cant do a back to back like we did with the stage 2 since the car is all pulled apart. weve already made our charge piping kit, and we have the exhaust removed.

Listen the boost is controlled to always make 260HP depending on elevation because Vegas elevation is at ~2000ft boost will be higher to deal with thinner air. And since this testing was done at a much lower altitude the computer will adjust the boost so its lower. Boost is just a number that can change Ive done testing from VA beach to West Virginia in mine and I gained almost 3 pounds a boost from VA beach to Virginia. But anyway 17 psi sounds like it would be full boost at this elevation.

Awesome. I'm glad to see someone putting time and effort into domestics, for once. Especially a quality name like Synapse. Keep it up guys.

Is your car stock or has it been modded in some way?

Believe me, if you had put your SC on our dyno the day we tested, you would not have been making 241whp.
But we gotta remember something here, we're not comparing dyno vs dyno.
We're comparing 2 different cars on the same dyno, on the same day, at the same time.
And that's what counts.

Thanks!
But it seems no matter how much I say it, someone will always remark "But I got XXX whp on XXX dyno."
So unless a dyno is used for the sole purpose of tuning an individual car ...
A comparison of one individual dyno to another individual dyno is an exercise in futility.
It's just a lot of "Blah, Blah, Blah" to me.

Upon reviewing the article that I referenced regarding Dynapack whp to crankshaft hp conversions ("Dyno Tech - How the Dynapack Works"), I see that they never mentioned anything about applying their "+20-25hp" to torque figures. So I won't either!
SS/T - 260 crank hp
Stage 2 SC - 250 crank hp
No reason to get overly excited there S/SS.
Let's just say for those two cars, that those are what the numbers would have been converted to.

)

Even though it's already too late to do a "Same Day/Same Dyno" test of a completely stock SC against the stock SS/T, we should still try to get a 100% box stock SC on Synapses's Dyno.
I'm going to query the owners on the SC part of the forum to see if we can get that set up ...

I'm looking for a stock SC to dyno on Synapse's Dynapack, which would make what you said impossible.
I have absolutely no idea what you're talking about ...
