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.

You know what's funny, the LSJ was made in Europe and shipped to America, the LNF is made in America. :usa:

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!!

small turbo's do that
:D

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

cakeeater 11-01-2007 04:45 PM

....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.

Have you seen an srt4 turbo? It's about the size of my palm...

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

I see a GT28RS being much more popular. 350 HP capacity, and they are some of the most responsive turbos available for a 2.0 engine. :twothumbs

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.

I thought ralliartist was running in the 13's on a stock LSJ (part wise) just with driver mods and tunes, and maybe traction mods?

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.

I didn't jump the gun. I wanted the LSJ more than the LNF. :lol:

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.

shabodah 11-05-2007 07:50 PM

There are Solstices in the 9's, but they aren't running I4's, lol.

Has anyone heard the numbers as far as what the stock LNF internals are good up to HPwise?

Do yuo have any times from a road course from say SCAA racing or any other? Are you comparing stock vs. stock or mod vs mod?

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.

stage2 03-09-2008 04:47 PM

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

So far, it has made 330hp and 425ft/lbs with just a tune by GM.:guns:

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.

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.

EtyrnuSS 03-10-2008 03:21 AM

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.

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

mdturbo 03-18-2008 01:18 AM

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)

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.
