Re: New dyno #s with the better exhaust 707.0 rwhp 721.8 rwtq About 40 hp and 40 tq. Not so much mandrel bends alone...but doing away with some restrictions and poor design over the previous setup.

New dyno #s with the better exhaust 707.0 rwhp 721.8 rwtq That is with the new mandrel bent exhaust with X pipe...still going through dual 3" Flowmaster 2 chamber mufflers.
I need to try it with cutouts or open headers next time.
Anyways...thanks to Brandon for the great exhaust!

Re: New dyno #s with the better exhaust 707.0 rwhp 721.8 rwtq I saw your setup a while back when you posted pics. You had some sort of tank to jack up your nitrous bottle pressure without having a bottle warmer. Are you still using the 5177 design that sprays in the lid?
Those numbers are crazy. Good job and how long with the 383 hold up ?

Re: New dyno #s with the better exhaust 707.0 rwhp 721.8 rwtq Yes...still using the basic Nos 5177 kit. Replaced one noid with a cheater and the other is T'eed to run parallel. Timing Tuner is a must with this setup as is race gas.
Clutch is the RAM setup..same one Alan at FMS uses (I bought it from his shop)
How long will the 383 hold up? That is the question. But if you look at the Tq #s they are not that crazy. Thats the beauty of the dual stage. I think it will hold just fine. I will likely step down to about 650 rwhp to gwt it dialed in at the track. Then...in about 10 months I plan to do preventative maintenece...tear it down to inspect and rebuild. We shall see...Im in no real hurry.
