Hi guys,

My guys have been sending me graphs from the 2008 Corvette all day but I did not get the one with just our headers. The numbers are 418rwhp 413rwtq with just LG Headers no cats.

Here is the graph that includes the K&N Air Charger on this 2008 LS-3 with the M6 transmission.

These numbers with just headers and filter match what a cam only car with headers and a filter use to do. So in effect the extra cubes and air flow in the heads matches what a Cam package would give up in the past.

thanks for your patience. 423rwhp 426rwtq with Just LG Pro Long Tubes and K&N!

Solid !!! This is great !!

Silverspeed

The torque is higher than the HP. How many LS2's with headers saw that? I don't ever remember seeing one.

HOLY CRAP!

That means a new 2008 with headers intake and tune is just about equal to a stock C6 Z06

WOW 10 months to go till I can order...its killing me

Good work guys!

How do you do the K&N? Doesn't the new intake have the MAF built in? Does that mean you have to put in a MAF when you do the K&N?

Thats crazy. GM made a big mistake.

C6400hp

Huh?

need-for-speed

Yeah, they really screwed up

Stingray23

You know what I mean. With about $3K in mods, a new LS3 will hang with a stock ZO6. Thats like canabalism.

need-for-speed

It's never a mistake to improve the base model. Remember, GM has to compete with other manufacturers, not their own Z06. The Blue Devil will take it to the next level shortly.

Not only that, but even with the LS2, for $5K in mods an LS2 car could hang with a stock Z06. It's not like reducing the mod cost from $5K to $3k is that big of a change.

This is a GOOD thing.

Which headers fit? 05-07 or Z06? O shaped or D?

Those are some great numbers!

I can kinda see what you mean as far as HP bragging rights.

BUT

I dont know about hanging with one. I mean, the Z still has alot more rubber to hook up and is lighter and has better suspension.

I do find it odd that GM's stated performance on the 08 is only slightly better than the 05-07's.

Could there be a possibility that all of this added power to essentially the same driveline/tires makes the car harder to launch?............. or were they lying about those numbers too.

Utterly amazing to see such great numbers with only headers and filter on the LS3. I must admit some envy. Congrats on the results

hardcore4sure

Does anybody know what the cam specs are on the 08.Those #s are crazy. Gotta be good for high to mid 11's at 120-124mph don't ya think?

LG Motorsports

The 05-07 C6 headers fit because the ports on the 08 C6 are about 1/8" lower than the Z06 so they might be a mis match if the Z06 version of headers was used. We like the round ports just because of the step at the head face to slow down the reversion but we can discuss that in one of the header wars

and the cold air is the K&N Z06 air charger.

Works like a charm

Thanks

I would think that the K&N being utilized here goes on after the MAF maybe?

And I'm assuming that the stock LS3 filter is just as restrictive as the stock Z06 filter element (some called it a thick brick LOL) is? So of course swapping it out should result in some nice gains, even on the dyno (as is evidenced above).

I have a 05' C6 and a new Z06. (see signature for MODs). The 05' is modded to the max. STILL the Z feels WAY faster. There is no substitute for low-end torque.

Lets not overlook the fact that this is with NO TUNE! That means one of two things . . .

1. Either the new PCM is smart enough to calibrate itself for the increased airflow, or

2. There's even MORE potential with a tune. 440rwhp with headers and tune?

Either case is a win for us 08 owners . . .
