thats why i'm waiting. i heard 315hp for the cobalt. if thats true i'll be getting one.

 

Obviously I can't speak for a MPG increase with the LNF in a Zeta platform, but according to "internet accounts" (take that for what it is worth) there have been increases in MPG both city and highway of over 1 mpg in the Solstice.

 

And kiss your warranty goodbye.

 

youre not gonna get the torque gain though, which is what you'll feel mostly while driving.

 

No gains on just the intake/exhaust as the stock program "tunes" it out. You need the GMPP tune or a custom one to take advantage of it. The car actually sounds quite nice with exhaust. the Turbo breaks up the "fart" sound of the I4 exhaust pulses and makes it more agressive sounding. Think of how the Buick GN sounds compared to a normal 3.8 V6.

I'm pulling around 2mpg better with the GMPP tune.

 

Lots more power and better MPG I think now I'd rather have the 100lbs. lighter LNF in a Camaro than the DI 3.6L V6

 

Hasn't Scott mentioned or was it Lutz that the LNF is being considered for the 5th gen after the initial rollout?

 

Sounds like a no-brainer to me. It would be great if they released it with a modified version of this Stage 1 tune. Something like 275hp and 320tq that got equal to or better gas mileage than the V6. Would the Camaro with the LNF be cheaper than the DI V6? Any idea how much?

Personally, I would buy a 3600-3650lbs. 275hp/320tq LNF powered Camaro over a 3750lbs. 300hp/275tq V6 powered Camaro. Especially if the LNF got better gas mileage and was cheaper. I am thinking these two cars would actually be close in performance too.

 

Dont forget that the V6 requires regular gas while any HiPo version of the LNF is going to require premium.

I want the alpha or whatever to come out so we can have something comprable to a RWD Cobalt SS.

 

I think it was Lutz, but that was when gas was $4 a gallon. He also mentioned a 1.6L Turbo for the G8. And then of course you have Z284ever that says a 3650lbs. Camaro is too big and heavy for the LNF

 

Kind of ironic when you consider 4th gens came with what 200 hp in the V6 models packaged for about 3500lbs. and a Stage II LNF in a 5th gen would likely be putting out 300 HP and 350 ft. lbs. of tq. So we're looking at roughly an 8% increase in weight if the LNF equipped 5th Gen came it at 3800 (being very conservative here) over a 4th gen and a 50% increase in power. Not bad IMO. What did the V6 in the 3rd gen put out to it's 3200 lbs.?

 

3rd gen V6 was, in the latter years, the 3.1L version of the 60 degree OHV V6. I think it was rated at 140 hp (I forget the torque number, maybe 180 or 185?).

I was just looking at a classic car mag at a co-worker's desk, and they featured the Black and Gold Trans Ams (the first year and the last year). One was a 455 big block (all iron) with 200 hp @ 3200 rpm (?!) and 330 lbft at 1800 or so. The later car was a 305 small block with 145 hp and 245 lbft.



The big block car weighed 3750 lbs; I didn't catch the weight of the small block.

 

Well, I don't know what an LNF Camaro would weigh. I'd guess pretty darned close to the V6, since it would also have the weight of the turbo and intercooler.

The question(s) then are:

1) Would you be willing to fork over an extra g-note for the LNF over the V6?

2) Could an LNF Camaro get better MPG than a V6?

3) What would the performance characteristics be in a 3750 lbs, LNF equipped car?

I'd imagine, you spend $1,000 more, get poorer mpg, and have worse performance when compared to the GDI 3.6.

 

1) Same money I'd probably take the LNF, $1000 more I'd only buy the LNF if it got 30mpg hwy or already came with the Stage I

2) In the HHR the LNF gets about the same mileage as the 2.4L. Plus the guy on here with the Sky redline that just got the stage upgrade says he is now getting 2mpg more

3) Same as the V6. Here is my take on weight. LNF HHR is about 50lbs. more than the 2.4L and the 2.4L Aura is 150lbs. lighter than the 3.6L V6, thus the LNF is probably around 100lbs. lighter than the 3.6L V6.

I understand market conditions are not right and GM doesn't have the money but it would be cool to have a 4 seater RWD LNF car. I hope Alpha makes it.

 

If the 2L Turbo gets same mpg as 2.4L in the HHR - and the 2.4L in the Malibu gets 22/30 (4spd auto) and 22/33 (6spd auto) while the 3.6L v6 gets 17/26 -- Then in theory the LNF in a malibu would get similar (or better) mpg than the v6. In Zeta? I doubt it.

I bet you're right - but I bet the mpg would be close. I also think NVH would be quite different between the two.
