300HP for Solstice?

[Beau]

I usually post some silly comment here or there but, there are a lot of very off comments here.

Such as somone saying the Sol weighing 400 lbs more causes it to BOG in the twisties in comparison to a Miata. Well, no, actually the 2.4 Sol beats the Miata in ever category, BUT the 1/4 if I recall correctly.

Another comment about the Solstice being bloated if it had a v6, tell that to the Twin Turbo LS7 somone installed in one, or the countless other LSx or V8s put in there. I would like a 400 horse car that looks awesome and weighs 3200 lbs.

For the other guy who stated that it was somehow bad for GM to do an overboost mode for the extra power, why don't you ask Porsche how they do it on some of their vehicles...

Honestly, I just wish that GM wouldn't go with that Morgue-Warmer turbo, it just doesn't flow much air, and it chokes out the car past 5200. If they used a larger housing, the car might even have better VE off of boost.

I'd like to know where the 40 horse is coming from though, it would be MUCH better if they just slightly increased the turbine housing and compressor wheel.

I don't need to ask Porsche how they do overboost on their cars because I really could care less about Porsches cars. They're nice but overpriced and the design is dated. In my opinion I would be disappointed if I was flying down the highway, when all the sudden I lose 40hp because I'm limitted to how much time the engine can hold the boost. If the engine can't hold that boost for sustained ammount of time then, find another one to make the power, more displacment, bigger turbo, whatever, but thats my opinion and I'll stick with it.

Let me know when you'll need to be WOT for more than 45 seconds at a time.

I'm not gonna argue with you as the point is quite moot. And honestly I don't think the thermal load has much to do with the bottom end of the motor, I believe it would be more of an EGT issue.

Since it isn't likey a motor design problem and more of an issue with turbo hardware, its likey they will just throw a larger intercooler on it, and add some boost and run the turbo clear off the map ( like it does near stock )

Like I said, a larger turbine would allow the engine to flow better an make more power. At the same boost level people are getting about 330WHP out of larger turbos with a completley stock motor, intercooler and exhaust manifold etc.

But whats the point in pushing harder if you add twice (I'm guessing here) the weight?

I think that small engines and turbo chargers are a great combination for the solstice/sky. Keeping them as close to that much desired 50/50 weight balance will mean a car that can go through the turns with more confidence instead of pushing like a dump truck from all that added weight up front.

Snafu_SS, that's what I was thinking too.... that's why a V6 TT (or just a larger turbo like Beau said) would be a great compromise. It only adds a slight bit more weight, but a significant amount of hp/torque.

The Solstice should not have a V8. GM needs small cars that perform... A Biopower twin turbo from saab, yes, but a V8? not really

Ah.... The GXP is already DI.

The 300 HP engine is a regular Turbo DI set up with improvements to the fuel rails and Intercooler. I have not seen the boost rating but I would expect it to be higher than the 260 HP.

GM claims they can they can do 320 HP with this engine and still meet emissions. So some where down the line we may get another boost..

I can not believe anyone bought the Camaro Monza story. It just proves you can just about throw any crap out and someone will buy in on the whole deal.

No wonder people buy in on Global warming.

See, i wish I could comfortably fit in this car. 300 out the LNF should be rather easy considering they claim the Ecotec is capable of close to 1000 with a hell of a lot of work done to it, but what isn't, right.

For seriously thou, I think this would be a good step in the right direction for Pontiac. As long as the price doesn't go crazy it would sell relatively well.

Ugh, I'll let this one go... it's too late to try to even 'debate' this, let alone educate.

Price and weight should nearly be the same and with this being a Pontiac only car sales should rise.

The high HP ablily just who this is not just another Iron Duke and that GM has a quality engine here vs most 4 cyliders in the past.

With what they have now GM has gotten 320 HP with outr going into the engine. The GOld car at SEMA last year sported 320 HP on GM parts.

GM drivetrain has some of the best engines around today and are still working. We have yet to see what the 3.6 sill do in the future. This engine will be the new work horse of the line up for the nest 10-12 years.

We will see great gains in mileage and performance with new DI and Turbo applications.

GM's liter vs HP is on the rise in all engines even the 2 valves that many said could never reach the level they are at today.

This isn't what I heard, where is motortrend getting its info? I heard...

700 hp V12 dually solstice sedan convertible with no doors and 3 trunks to address the lack of storage. : P

Then buy a Corvette. I did.

Pretty sure the ls v8's are barely heavier than the majority of the dohc v6's (especially with a TT), plus the weight is concentrated lower.

i'd be on that line to buy if this came to reality

I agree. The Gen III + all aluminum small block engines are very light (and physically small) for their displacement. I wouldn't be surprised if the DOHC 3.6L v6 is close in weight anyway, add in the turbo(s) associated tubing and hardware, an intercooler, etc., and the LSx engines may even be lighter.

Either way I think a 2.0L Turbocharged I4 at ~300 hp would be a good fit for the car.
