Those interested in Magnuson kits for F-body, step inside
I've been keeping up on his random threads about this kit for a bout a year or so, and I'm really stoked. I cant wait to see some numbers and video! Talk to you soon Ed.Santino. //
The 78mm t-body inlet starts to choke at around 520 rwhp. When Ed offers the 90mm inlet option, it should be good for almost 600 rwhp and the case size becomes the limiting factor. I've had two similar setups, with both T-bodies.
348ci LS6, 9:5 CR, ported LS6 heads, 230/230 114 cam - 505 rwhp @ 9 psi boost
366ci LS2, stock CR, stock LS6 heads, 230/230 114 cam - 550 rwhp @ 5 psi boost
The additional cubes helped some, but I'm convinced that a 90mm t-body on the first combo would have made closer to 600 rwhp. It pretty much stalled at 505 no matter what we did. I would have also just left the CR in the 10.0 to 10.5 range on the first combo, if I were to do it again. Both cars had 1-3/4 longtubes with offroad exhausts.
Here is a video of how the 2nd combo runs:

The first combo was in my '69 Camaro, it ran 10s on a pro-touring suspension.

Sure, the bigger engine is helping, but 20 more cubes isn't making that much difference. It's all about airflow!

Thanks Darren,
The Y pipe is great! I had to loosen up the clamps, and adjust it a little, but no more rattles since. PM me the next time you go up to Hall's and I'll meet you there..

Is it possible to lower the engine another .5" via a custom motor mount, or is the front K-frame bar in the way? If so, could you get away without cutting anything for the magi?
Nine Ball, on your second setup, can you go to 9 psi? What kinda number would you get if so?
BTW Ed, Nice setup!!
