try running a decent sized cam and see what kind of piston to valve clearance you have in the hemis.

my post was in reference to saying the LS3 is peaky. it makes 95% of its peak power from 5300 rpm to 6500 rpm, the rpm where you will be WOT. even if it makes 340 whp in auto form (the auto L99 is rated lower, im assuming you already knew this) that is at least a 325 whp average from 5300 to 6500.

you really can't tell how long the stock hemi holds power as they shut it down right after they hit peak hp.

i've been to the track with my current set up where I've ran 12.862 @ 111.158 vs my friends cam, full bolt on, geared, 6 spd WS6 coupe that ran 13.184 @ 110.677.

that's at sea level back in april.

i've been to the track where my H/I/C + full bolt on 5.0 was only trapping 104's vs. the usual 109's and my friends WS6 had lid, exhaust, cutout, pulley, MAF and he was in the 105-106's.

I've seen '02 Z06's struggling in the 109's-110's.
I saw a GT500 trap 104.
I've witnessed SRT8's trap 100's.



the track is a funny place sometimes.

Based on weight alone, the SS should have a small advantage over the SRT-8 in straight line acceleration.

As for the pic above of the two Challengers...I've seen 03 Cobras run low-mid 14s stock, and GT500s run high 13s stock, so one pic of two under-achievers really doesn't say much.

No offense HOTCIVIC.

TrickStang37

that's just one example. **** happens. I've personally have witnessed a stock 93 LT1 automatic beat a 99 SS 6spd from a roll. No joke. **** happens, too many variables.

yellow_99_gt

Nope, but it's also no reason for it to be slower than the other 3 SRT-8 LX cars.

Highlander

Wow.. i sure hope they aren't underachievers...

now.. ls3s pumping 475 with bolt ons??? that is very impressive... then why buy a z06.. the ls7 is a CRAP super crap engine... because after a tune with bolt ons we managed to get 474 out of one... Wow.. GM should replace the ls7 with the ls3 in it...

HOTCIVIC

True. I've seen C6 Z06s run 14s so anything can happen I guess.

HOTCIVIC

I sense sarcasm in your post.

The LS7 is extremely responsive to mods as well. They put down 450 rwhp stock and some have put down 480 - 490 rwhp with just a tune. Cam/headers/intake 550 rwhp plus.

Both the LS3 and LS7 are impressive motors.

TrickStang37

most LS7's that I have seen put down 440-445ish rwhp. stock

HOTCIVIC

440 is probably on the lower end, 460 on the high end.

HOTCIVIC

To be fair to Dodge, I've heard after 5k miles there is some sort of timed hp release in the computer which will wake them up a bit as well.

Yeah, and if the SS comes in at the price range I am hoping, $30,000 base
SS, then it will really be kicking butt in more ways than one. Yeah, I know,
pricing not out, but something tells me $30,000 base SS will be close.

The biggest variable that people always forget is the driver!! A bad driver
can make the best car look like crap and vice versa.

All may not be as it 'seems'. The G8 is underrated from the factory if dyno numbers are any guide. But you seem to rely on just factory engine numbers and then forming a conclusive opinion...

TrickStang37

They are not "underrated", they only make ~300 rwhp. They do have very good gearing, they are at the VERY VERY top of 3rd when they cross the traps. Doesn't get much better than that from the factory (unless you have an ISF), most automatics are midway through third when they cross.

The L76 is a certified engine, "underrated" is a bunch of bs that doesn't exist anymore* (*for SAE certified vehicles).
