10.3:1 CR + 12psi and a GT9 cam on 93 octane will be right at the edge if not beyond.

I don't know why Andy said 600-620 maybe he missed the 417ci part? Should be 700+ rwhp.

Look at those LSA motors doing 700+rwhp with only 6.2L and about 14psi of boost from the baby yet efficient 1900 on pump gas.

I say go Lsx and never look back...
This!

I had one in the SS I just traded in.. actually it's still for sale haha.

I did however change the Cam, it made it better off the line. It was a monster.

They failed to mention it has an LSX376.. Cammed, full exhaust and all.. It passes inspection too.

My thoughts exactly. If a V, with stock cubes, a 1900, and a LS9 cam makes @ 650 rw, then a 417 with a 2300 and a GT9 should be 700+, assuming you have a fuel system to support it. At least I hope.

Don't forget we're talking A6 here. GT9 cam is going to choke that big motor a little. More cam would sure help.

Remember though, engine size means nothing to a supercharger. Boost is only a measure of restriction, not total airflow. A 2300 supercharger can only move x amount of airflow, which will make x amount of HP, no matter how large of an engine is underneath of it. Factor in the auto, and you are talking about a combination that would make ~650, but 700 is a stretch as the blower just cannot move enough air to be efficient at that level.

Which is why I love turbos. 12psi, stock l99, no heads, no cam, no headers, no cais, no tensioners. 680rwhp/740rwtq.

There are numerous A6 CTS-Vs with LS9 cams putting down @ 650 rwhp. I figure a LS9 cam on 376ci is like a GT9 on a 417.

Ive read that all things being equal, every ci = @ 1.5 rwhp. Hoping for something like this build of Andy's. http://www.camaro5.com/forums/showthread.php?t=289999

Damn...Bad assed Caddies. How much boost are they using to get those numbers? Stock short blocks?

Forged rods and pistons, stock displacement.

Id like to see your car on the dyno with the nitrous shot to see what you are REALLY making

I thought it made 750. Ted said corrected it was 732.

680 with no nitrous.

Ya that sucks!!! Not sure how you can drive your car around without being embarrased!!! LOL

I have a long way to go until I am even close to your 680.

So riddle me this, if the Maggie can not feed a larger displacement engine to get HP level into the 700 RWHP range, would it not be better to go with a smaller displacement motor built to the nuts and with a displacement where the Maggie could still make some good boost numbers?

I have pretty much decided on a Livernois 416 Pro series short block with roughly 10.7:1 CR. Running around 510 to 540 rwhp right now depending on which tune and what octane fuel I am running so anything 650 rwhp or over will be a big boost in performance.

I drive the car with a ski mask on to hide my shame.

I don't care what anyone else has to say but every 416 Maggie camaro I've seen run at the track is my cars bitch. Ok, so you squeak a little more power. Gd for you. The tvs seems to like the 376 for optimum efficiency and production. The blower itself is now limiting the power.

Depends on your goals. Personally I would rather have big cubes, which may limit boost, and make up the difference with compression. I don't live at the track, so for street driving I think it will be great. Seems like you and I have similar plans with our builds. If someone is trying to build a track car for the best e.t. possible, it seems Jamie's car is the gold standard.

Ya, street performance is far more important to me which is why I am leaning toward a 416.

I disagree with parts of this , in the current design ( out of the box) from Magnuson yes! With the addition of porting the lower tub elevating the intercooler while isolating it with phenolic s and increasing the throttle body size additional cfm is found by removing restriction...
I just put down 678 rwhp and 770 rwtq @ 8 psi on 91 octane
Using a stock 6 rib drive front and a 10 rib rear overdrive
Belt slip is clearly an issue on this combination, however it does clearly show the potential of a 2300 on a properly designed 7.0 specifically for the tvs2300.
I currently own 2 of the first 5 tvs2300 released to the public back in early 2009.
Pushing the limits and raising the bar of the TVS2300 is how RDS was created

Yes Dave does our business to business sales. He would be the one to contact about becoming a dealer.
