ok the fact they had smoothing at 5 and did a run w/ shifts is just retarded.

NTM does anybody even know what ECU the 'balt will have? if it's the same then the "bsr tuner" may be compatible (barring dif OSs), if it's dif then this whole thread is (likely) moot.

Either way, with the Cobey being turbo, I believe that there will be some pretty decent potential involved, ESPECIALLY if GM made adjustments to the drivetrain to correct some issues that were had such as the tapered axles.

I think this is good news, the turbo Cobalt part of it that is. lol

The Solstice auto will not stay in gear, it'll auto shift up once you reach a certain point. It makes it very hard to do dyno runs on autos.

It's the same ECU as the Solstice GXP;

lmao that is not going to be good. atleast what im getting from all the info i have read that if you turn the boost up your going to screw your turbo in the long run because it is too small. if you want to push higher PSI you need to swap turbos.

True, but at least the LNF cobalt guys won't have to be the guinea pigs like the LSJ guys are. They can look and see what works and doesn't work from the RL and GXP owners.

those numbers are okjay...we got some ss/sc pushing 280-290whp

im just one of a handfull actually

lets revisit this once the LNF cobalt has been out for 3 YEARS!!

Go back and look at the ss/sc # from 2005, early 2006 we weren't in the 280-290 range.

I believe that the spring rates were changed probably to reduce wheel hop..axles may be the same

Im going to quote from another thread:

the axles for 2008 are new designs . They focused on dampening the harmonics that traveled thru the axles caused by wheel hop . The harmonics is what caused them to crack in the old design .

those numbers are okjay...we got some ss/sc pushing 280-290whp

Show me an LSJ running almost 260whp from a tune alone. The guys running those numbers with the LSJ's are running delicate tunes w/ full bolt-ons and meth injection. Not to mention the Cobalt with the LNF will see higher numbers due to less drivetrain loss.

thats why you swap to a twinscrew..

Yeah lets go spend 3k on what 30whp?

No doubt . For us , its a bit more involved than playing with the computer .....I think that was the point .

does this thing come with a front mount. I ouldnt tell in the picture all that well. If it does that seals the deal, tommorow at work ill talk to the sales manager.

Im going to quote from another thread:

yeah ive NEVER seen the axel's crack. i HAVE granaded a driver side axel at the inner CV (the one that slide's into the hub) i hope they redisgned everything. espically the trans housing.. cause some poeple were cracking tranny housing's BEFORE snapping an axel. and ending up with a voided warrenty for racing.

Yeah, I thought I broke an axel at the track but it ended up being the housing on my 06. They threw the V word at me and I talked them into fixing it under warranty. But yes. New and improved (hopefully) axles will be good. Hopefully the new motor mounts wont be oil filled either.

thank god my eyes werent decieving me, A nice frount mount is all really wanted. I wonder what month exxactly these will be hitting the lots. Since I do all the PDI's at work, as soon as we get some Ill get a video and post that up. Better get my finances in order. Tradeing in my 05 2.2L for this would sure be nice.

^^ Think April'ish . 2nd quarter is april/may/june . They should have a more specific date by the autoshow season .

i put down over 260 with a stage 2 pulley, intake and a cat back, and a race gas tune

hell i put down over 260 with a 2.8, stock tune, and an intake.

how is the drivetrain loss in the lnf cars less than the lsj?

I was talking the LNF cobalt will see higher numbers due to less drivetrain loss as opposed to the solstice GXP and sky redline. Considering all the dyno's of the LNF we have so far are from the GXP and RL, the cobalt should spit out numbers a little bit higher.

irs = sucks a lot of power.

Not quite. Normal equation on a manual C6 would be 15% for the 6spd and 18% for the 6spd auto. Doesn't eat THAT much.

The Sky should see the same 15% for the manual and 18% for the automatic

People need to stop sugar coating numbers.. Ohh higher drive train loss.

Not to mention a bitch to launch, not that FWD is any better.

ding ding!

lol:lol:

for the ding ding guys...you realize these lnf balts with TBE's and a tune are gonna be walking all over the 2.5" pullied cars with cooling mods, the works. Don't kid yourselves into thinking it is not a worthy upgrade. "oh the turbo is so small stock, you can't up the boost that much!"

do you guys realize how much power is on the table for the aftermarket with pretty much any production turbo car without even touching the stock boost level.

I dono how the turbo is set up on the lnf, but the good old up/down pipe combo's (no cats) with a catless setup from the turbo back along with a tune will yield you some great gains, throw on that intercooler and watch the 300whp. for fairly cheap.

but how much is that tune??? exactly. a thousand bux.

the loss from the rear end of an irs is about the same as a 9 inch rear end. the ford 8.8 sucks the least amount of power.
there is many factors as to why irs sucks more than a solid. moving parts mainly, and rear end size itself. friction loss vis fluid. blah blah blah

ford 7.5 sucks less. And it can be made real strong real easily. Obviously it's not worth swapping to a built one from an 8.8" in any car equipped with it stock, but some of the guys with v6's that are pushing some big power numbers (usually the turbo guys) use 7.5"s with detroit true tracs, welded axle tubes, etc and they are putting down in the mid 500's torque wise.

but how much is that tune??? exactly. a thousand bux.

Yeah the tune is expensive. The Bosch systems on these DI motors are very new and infact i think they BSR tuner was imported from europe since they at that point were the only ones able to hack into the ecu's. hptuners is working on getting them cracked as we type but haven't heard anything latley as to the progress made.


it's not. looks like someons is just making up new rules :lol:

And before you go and make a cute ass fuckin comment go read my reply to Area47's comment, I was talking Solstice GXP vs LNF Cobalt. Not every post about the new LNF is comparing it to the LSJ.....

So we might be looking at 245whp(ish) due to the slight gain in drivetrain loss from RWD to FWD. I can see these cars at 350whp about a year later.

In all the LNF will be better. We all know it. We probably just wont admit that we jumped the gun on the SC version. But for myself. I would rather have a SC car than a TC. But power wise, get ready SC's

They should've kept the SC, its just American and non-rice (IMO!!!) for a American car to have its power from a fat V8 or a whiny ass supercharger tearin up the streets.

This graph shows the main benefit of the LNF over the LSJ. Even with all those mods on the LSJ a bone stock LNF makes more Torque and makes it sooner. My RWD LNF put down 243 ft-lbs to the rear wheels stock, and 90% of that is available at 1500 RPM.

The LNF might not be underrated for HP but it is underrated for Torque. This engine makes more than 260 ft-lbs stock for sure. The BSR tune puts it at 330 ft-lbs (crank) on just the tune, and the announced as of yesterday GM Stage II makes 310 ft-lbs.

I'll admit I jumped the gun on the S/C version, knowing that the turbo wasnt far off. When I try to visualize trading in for the SS T/C though, I just can't bring myself to do it! I love my S/C whine!!

any of the sols/sky's with the lnf's int he 12's yet?!?!

....why does everyone think that turbos are ricey? ever heard of the mustang svo, the buick grand national, the turbo firebird/TA's, etc? some great great cars, and what a surprise the some of the top cars to modify for their time. Turbo's are as japanese as front wheel drive is. I doubt alot of you have driven a good turbo car.

Not yet, people are still trying to get the tuning and mods down right. The Hahn Stage IV base Solstice is in the 11s though with a bolt on Turbo kit, so I'm pretty sure we can do 12s once we get everything down with the engine.

I see the gt3071 being a really good turbo upgrade, some lag but great power

That's also a 2.4L solstice (LE5?). Not a LNF engine. The 2.4L I wouldn't doubt would be much easier to get into those numbers. That car has between 400-500rwhp.

Yeah that was a 2.4l but its NA from the factory, LNF being turbo from the factory would make one think it would have stronger internals. But yeah the hahn 2.4 stage 4 had 390whp the last i saw.

True, but at least the LNF cobalt guys won't have to be the guinea pigs like the LSJ guys are. They can look and see what works and doesn't work from the RL and GXP owners.

Its never good being a guinea pig, thats why I wish I would of went back to my old root of 60s muscle cars...

Compared to a moped. :lol: And as far as a road course is concerned they were some of the lightest and best balanced stangs around yes. But one bad move on a drivers part adn they lost all their momentum.

i would go and buy ss/tc but after putting 3,000$ mods in my car....not sure that i wanna go and buy this now

They should've kept the SC, its just American and non-rice (IMO!!!) for a American car to have its power from a fat V8 or a whiny ass supercharger tearin up the streets.

Well, you can blame our "wonderful" enviromentalist hippie I-want-to-tell-you-how-to-live asshats and congress for the demise of supercharged production cars. ZR1 excepted of course;).

On topic, its cool. If I didn't already have the SC, I would be looking at one of these.

tune and 3 inch catless. its on their site

so they got 330hp and 425 ft lbs at the crank... so with a full 3 inch catless setup and a tune they probably dynoed ~280whp 360wtq. That's not bad, but im wondering why it is lacking so much in the hp department. What turbo is the lnf running? Im assuming its pretty damn small and they are runnin high boost with that tune and its gettin HOT up top.

what are you talking about? the ss/sc didn't fail to meet new specs just because it's supercharged...there are ALOT of supercharged vehicles still.

Maybe I should have been more specific.

From the C&D article on the TC: The SS Supercharged had to be discontinued because its blown four didn’t comply with emissions regulations for 2008.

Maybe not all SC cars, but ours, the SC 3800 series engine, both due to this.

still one of the stronger turbo 4 cylinders to ever hit the market, and it started quite a trend of performance 4 cylinders...i'd say a pretty great car for its time.

It's amazing what they did with the RS200. I'm not really a Ford fan, but that thing was a beast.

http://en.wikipedia.org/wiki/Ford_RS200

The turbo is tiny. It's similar to the Borg Warner K04. It'll be one think you'll want to upgrade down the road... Right now folks in the GXP/Redline community are working on turbo alternatives. The retarded GM flanges don't help. Working on that too. :O)

what are you talking about? the ss/sc didn't fail to meet new specs just because it's supercharged...there are ALOT of supercharged vehicles still.

the federal government said that all 4 cylinder cars will be held to a standered of a 32mpg rating accross the board. the SS/SC did not meet that factory rating no matter what people actually got out of it. What GM rated it at is what the government is looking at. So there for the SS/SC had to be taken out of production. To bad too, they might have switched to the GEN 7 M62 had this not taken place.

WTF, since when government do they govern based on engine size? In the US, they govern based on overall mileage for a vehicle and the corporate average.

They don't and the new law which requires all vehicles to have i believe 35 mpg in 2020 so not to worried about that!!

Thats a completely false statement . The LSJ engine did not meet new 2008 emissions regulations . Fuel econ had 0 to do with it . GM designed and put all its money into the LNF as a performance engine it could use globally , a supercharger was never an option . This engine eventually will spread to the next gen Astra , Saabs , gm's new RWD alpha chassis cars .
