Now I was wondering what the LNF would be like supercharged. What kind of numbers would be seen with the addition of direct injection that the LNF provides? Just wondering if anyone knows.

 

that sounds awesome id like to know to

 

See "supercharged LSJ"

Probably close to the same #'s the LNF is putting out.

 

with the direct injectors you probably put a lil more down

 

Yeah that was what I was thinking. The LSJ has had a turbocharged twin that people over look. The saab 9-3 2.0T is the same LSJ engine but Turbocharged and has 210 hp at 12.3 psi. Man I am hella curious now to see a supercharged LNF.

 

Turbo > Supercharger
except off idle torque

 

it would put off identical numbers. With the heat that the supercharger gives off, the lnf would be forced to run richer (in stock form) in order to help cool the charge down a bit. I could maybe see a slight gain up top from the VVT. But that's about it.

 

If there is a supercharge kit made I will buy the turbo just to convert it!!! But who knows??? If anyone does this I would expect them to use a TVS or twin screw.

 

Good question, but doesn't make a whole lot of sense practicality-wise. I love my supercharger to death, but in all honesty, turbo will always have the (modding) edge.

 

It would gain a little bit. The new 3.6 v6 that is in the new buick enclave is di and it makes 290hp but the 3.6v6 in the G6 gxp is port fuel injection and makes 260hp and it is the same engine just different fuel injection.

 

I know turbo has the modding edge but the cobalt being supercharged is unique now it's apart of the many turbo cars out there. a new engine with direct injection and vvt with the same supercharger would of been unique and a launch control system can make some great launches with all the low end torque. Say if it made 250 hp stage two could be used still and hp could possibly be at 285-300. This would be bad ass and for around the same price. I love superchargers.

 

Now why the **** would someone want to supercharge a turbo car??? Why didnt you just buy an SS/SC then and save the hassel??

 

Launch control on a SC'ed LNF would be more useless than it is on a stock TC. You spin and spin on stock tires. It's not really "unique" either since the cobras have been supercharged since 2003. If you're talking about 4 bangers with SC then you can see why everyone else is turbo.

 

I do own a ss/SC I just hate to see it go turbo.

 

The power the ss/sc makes on the m62 has little to do with the fueling system. so changing out to a 2.0 VVT engine with a turbo cam profile is not going to output 30-50+hp. Yeah the DI would allow you to run a **** ton of power without ever having to replace the injectors/fuel system, but the m62 is still going to flow the same amount of air and thats where the power comes from. The turbo on the LNF can flow a higher amount of air more efficiently then the M62, thats why they make 275+whp and 300+wtq on boltons and a tune. Its a better platform then the Heaton but is just about at its max as well from the factory. The power output has little to do with the VVT and DI.

 

It would still make at least 15 more hp in stock form

 

i highly doubt that. DI wont really add any horsepower...how would it? and VVT might add a bit, but idk about 15hp..especially with a turbo cam profile

 

Doesn't the LNF also have lower compression? It would be seeing the stock boost of the S/C instead of the higher TC boost.

 

that will be a heck of a project if someone does it. It will be nice. Hands down a ss/sc sounds better than a ss/tc.

 

thats an easy project....$1,500 in parts and about 12hrs for install
but its also a downgrade....and no one would want to...less HP, less tq...more lag...

 

 

OMFG... subscribed for LOL's.

 

EDIT

 

Wrong buddy.

LSJ has 9.5:1

LNF has 9.2:1

****,

Well I am going back to sleep.
