Some LNF #'s w/ upgrades
 

Via the solstice forums:

stock LNF 239whp
Hahn BSR tuner only 258whp
BSR tuner w/ upgraded intercooler 268whp.

All on stock intake and stock exhaust.

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;

those solstice guy's BEAT there cars... here's a SKY RL with 275 RWHP 305 RWTQ STOCK jus retuned to 23 psi...

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

ding ding!

yes that'd be you

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:

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.

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.

yes it does

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 .

OMG .... a sporty car thats being released in the dead of winter ( solstice , 05 vette ect )

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?

Okay here ya go 2.85" pulley, toon, downpipe, 2.5" exhaust, intake!

No methanol, no cooling mods! Just Area47's tunes!

what about swapping with a srt4 turbo

999 for a tuner? Jesus christ. I thought my E55 was expensive to mod

Uh, why?

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.

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.

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

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.

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.


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.
