I posted this in the Tech page but since many of you went through this, I wanted to ask here as well. I'm looking to see who's got what. Not looking for 1/4 mile times, looking for crank hp/rwhp numbers from N/A LS2's. Prefer A4/A6 but M6 info would be good to know. My combo is 480 rwhp with stock bottom end and wanting to see what else is out there. I'm thinking about a supercharger but want to see some before and after examples.

740 RWHP for over 5 years supercharged

I have a stock bottom end, and it about 650/550 @ 6#. I am now at 10# and I am going to get the car retuned soon and I'm sure to be over 700. I will advise that if you plan on making lots of power, be smart and buy a tru cool 40k. It will keep the heat off the transmission. Well worth the 100 dollars when you think of transmission rebuilds are over 4K each. Let's just say the stock transmission will not hold up if temps are high. I have had the procharger setup for over 10 years.

Made 760 through a manual transmission. Ran like that for 8 seasons before I decided to do a new build with significantly more power.

Supercharge it and don't look back. The secrets to long life of the stock internals is good tune, always good fuel (I splashed a couple gallons of MS 109 in each tank) and regular maintenance.

Make sure your tuner knows what he is doing.

Make sure you have a proper fuel system.

Run meth.

Be aware of what your car is doing (in the immortal words of Ty Webb, "be the ball")

Mid 700s is common

schpenxel

14psi, E85, cam, stock bottom end otherwise.. 50K miles so far, so far so good. Not sure what that is RWHP wise but it should be a good bit

Avoiding knock is really the key. E85 and/or meth

453rwhp/417 rwtq when naturally aspirated with cam and bolts ons... 2005 LS2 M6

722rwhp/654rwtq with A&A v3-T on E85 @ 9psi (forged bottom end after 2 failed lifters wiped out stock bottom end)

Thank you. You're the only one who mentioned what I was trying to find.

Making right at 800 rwhp. on a Dynojet. Was 730 rwhp on a Mustang when the tune was first done. Only internal mods are cam, springs and pushrods. Using Meth but not turning up the power with it, just using it for safety. Engine wants much more timing and can probably make a fair bit more power with timing but keeping it safe so making slightly less on Meth than without. M6 car.

My 2005 A4 makes around 430hp 440tq consistently on different dynos. Cam, intake, full exhaust no cats. Going to spray a 100 shot soon.

Thank you for reading.

Dimewise

You do realize this is the FI/nitrous section right? lol

mbowers13

Does that mean reading comprehension is optional?

BoosTTed C6

Most of us didn't dyno the car as a baseline before the mods because we just don't care. That being said, mine made 374 whp with headers, intake and tune. I'm guessing 330 to 340 was stock whp. Blown power listed above your snide posts but beneath your original post.

Ant-Man

510rw with heads/cam/exhaust, I don't know crank.
700rw v7 on 6-7psi

Both on 93/m6

mbowers13

What did you do to get that 510? Yours is LS2?

0Billy@MTI

The LS2 is very strong for a non forged piston motor. We have pushed them much higher than LS1, LS3 and way stronger than the new LT1.

Ant-Man

Yea a little 100,000+ sbe ls2, currently at 115 and 700+ daily driven.

A mix of:
Custom ground cam
PRC heads that brought the compression up a little
ported stock tb + fast 102
headers/cat delete
vararam

I literally swapped everything but the cam back to stock when the blower went on. It's a NA cam but I'm too lazy to open it up that far.

mbowers13

Thanks. Do you mind sharing your cam specs? What did you do with your FAST 102?

I have a 80k miles sbe ls2 m6 it made last year on a mustang 733 to 7k rpm I beat the **** out of it Every time I take it out
