How much rwhp are you ls7 NA guys making these days

landonew · 01-17-2008, 09:23 PM

Love the new z06s, and was wondering what you guys where making w/ H/C on stock cubes (as if 427CIs ain't enough). Was thinking of getting a Z after law school (meaning after I pay back the loans so they don't chop my legs off) for the DD. Course by then there will probably be a C12 z06!

I'm running (was running) 535 RWH and 493 RWT with my forged LS7 in a 2001 WS6 Trans Am A4. It's tore apart right now getting more stroke. This HP stuff is addicting!! Traver

NICE. More Stroke??? How long has the new block been under the hood?

I had about 20 track passes and maybe 2500 miles. I always want to be on top in my neighborhood and there's a '74' Dart that's a real pain in the arss! It's pretty well a racecar, tubbed, lexon windows and 14.1 comp..........all that good stuff but I'm still gunning for him! Good clean fun and it keeps the blood pumpin and the heart healthy!!

Oh ya, I'm putting a 4.125 stroke in it and porting the heads some more not to mention a couple other little tweaks!

Damn!! Makes me wish I had gone w/ a stroker package. Whats the best ET? MPH? Any videos?

We have built a 611rwhp LS7 in a C5. We have built a few cam only 580+rwhp C6Z06's.....our standard smaller LS7 cam which is pretty mild-med usually does about 540 to the tire. With the right cam and heads the LS7 is capable of big power.

check the corvette forums,lots of 427 mills in there. the qm600 cammed 427s with ported heads/intake are putting around 600 to the ground.

mikey · 01-19-2008, 12:20 PM

570's up to 612 rwhp...

STROKER R/T · 01-19-2008, 01:32 PM

no flames to any one tuner !!! however you may fine some big hp 550 to 600 rwhp bragging ### s with no track slip & weight to back the hp !!! claim !!!! i've had 525 rwhp 427 & 560 427 ...dynos some times ..make your track slip ..a puzzling thought !!! my 427 best on NO2 TUNE 10.6 127..OTHERS SAME COMBO & parts 9.9 132..hope this helped

ramairws6 · 01-19-2008, 02:16 PM

I'm not embarrassed to say my track times at 535 RWHP. I was running 11.1's in the quarter and cutting 1.49 60ft times on Nitto drag radials and a hefty 3,820 race weight. I could never launch off the line more then 2000 RPM's cause my Nittos would bust loose everytime! If I would of had some Bogarts and drag tires I would have definately broke the 10's. Check out my video in the 11 second section of the board. Traver

bandit1 · 01-19-2008, 06:41 PM

nice video traver just went and saw looked good

ramairws6 · 01-20-2008, 08:29 AM

Thanks Bandit1.......and believe it or not this was before my QM600 swap so I definatley know the 10's were there! I will never know now though? Got to start all over with the 441. I hope I don't go backwards!?

bandit1 · 01-20-2008, 10:34 AM

you'll do fine boss have faith my brothera hahaha looking forward to seeing this thing come together keep us updated

ramairws6 · 01-20-2008, 11:22 AM

Do you know why Rev Extreme claims only the 95 mm TB will fit on the lS7 intake?

bandit1 · 01-20-2008, 03:47 PM

Have no clue i have the 100mm on there and it fits fine I will say that it is just barely and i can see the edge of my seal but its sealed just fine. maybe they mean that the 100mm will just barely fit I dont know

Well - I for one am preventing one such tuner from posting drag strip time slips... as I didn't have my 600rwhp LS7 car built to thrash down the 1/4 miles strip, but rather beat up around a road course..

The last thing I feel like doing is blowing the stock 2001 rear end on my car "proving a point"

ramairws6 · 10-12-2008, 01:50 AM

Just to update since my 441 build is done. I'm now at 564/516 at the rear wheels. It doesnt' seem like much more but through a 4L60e and a Ford 9" I don't think it's too bad since I did run a 10.46 at 131 MPH the first time at the track. Also got a 6.4 at 110 MPH through the 1/8th before I got the boot for not having a bar!

chieftransam · 10-14-2008, 12:09 PM

Are the 427's you guys are building streetable? I'm looking to go either 416 or 427. I'm leaning towards 416 since I'm told I could still use a little spray or boost. I'm told the 427 isn't really for boost or spray. Any input?
