Oh, she'll come around! This is early on, only a handful of dynoruns on this car so far. There's much to be had with tuning as we get more aggressive with it. It's also a FWD car, so making boodles of low end torque is just not on the menu, although it will certainly improve. We were just kind of jazzed with the HP produced on pump gas!
At this juncture, on pump gas, we're taking it easy, and the boost control system isn't cranking yet either...the boost curve follows the HP curve, so at low rpm, it's also still running very low boost. She's far from optimized. I'll post up some more when we go for the gusto!
That sounds better, i'd be disappointed if that was all you'd be able to get from that setup.
I also noticed the power curve on the dyno sheet was very linear compared to others I have seen with this much hp from a small four cylinder. I could be wrong in my assumption, but it seems like the progressive nature of the power would really help a two wheel drive put down usable torque compared with other curves that show sudden increases of power within 1,000 rpms or so. On the street and on the RR tracks, progressive, usable power is better, safer, easier to drive and probably faster. Am I wrong in this assumption?

So when are we gonna see those numbers on the LNF?
All it takes is the right person. We already have the technology!

You're right, Jae...as opposed to a more abrupt power onset, this is a very gentle curve that would have a tendency to maintain traction without wheelspin.

the curve is going to give a more granular throttle response imho

Don't think anyone is trying to impress other car owners w/dyno graphs. Those impressions often prove themselves at the track, not dyno queens. Although, it's always nice to see the numbers on a graph and then discuss them. The proof is in the pudding.

I could be wrong, but just by my experiance you don't need much Hps out of the Sol to make it a fast car. That's the good thing about this car. You don't need much money to build a fast solstice. I whipped on 400 plus hp cars and more with my Hahn stage 3. I love to argue with people that say they would out sprint me because they are pushing 480+hp. Honestly i don't waist my breath on stock STI's and Evo's. Even the modded ones i made a very noticable pull on them. Some say it's because i'm light off the line so then we did a roll on. Yeah! Not much said afterwards. Sorry, but blame it on my Hahn system that made me arrogant.

more manageable horsepower...I remember one of the professionals that had the gm tune and "go fast parts: said horsepower that high on this car was either all or nothing so a more controlable throtke
It's not a matter of which is better super or turbo. It's in the facts that a properly turbocharged vehicle will be all in all better than a properly supercharged one. That's just a fact. Most people on here didn't even know anything about either one, and now they say this and that because that's what they bought. Plus look at Ferrari and the Lambo's out there, lots of HP not as much TQ, so don't under estimate that output. Only considering all 4 cylinder sols here, that car would wipe up any of our sols on pump gas, and most on race.. Using a positive displacement supercharger to me is like using a turbo that is too small,, it will feel good down low and you could get it to work in higher than normal HP ranges, but you'll just be pissing in the wind example the Nissan 300 zx. Another thing people talk about is the lag of a turbo, confusing that with boost threshold. They are too different things
Nonetheless, beyond the apparent implications of GM's choice to end superchargers, and go turbo (they had a number of good reasons, two of which Jack indeed touches on), I can also provide some decidedly non-biased documentation as to their choice. Anyone care to see this?
Yes,, I do!!! Not for me though, for everyone else..
