So...to date you have upgraded the exhaust and put on the GSM sc with 8 psi and you think you have about 400 hp at the wheels? Have you dyno'd that? It certainly matches the numbers published by GSM.
And...you plan another upgrade package to add 200 hp at the wheels? What is this "new package" that you are referring to? Are you planning any upgrade to the heads and cam or are you going to 15 psi of boost?...never mind...I found your earlier post http://www.300cforums.com/forums/per...light=ahlquist
. You are putting in a 6.1 with ported heads and 14 psi of boost.
You also say in that post that you blew 2 rods through the side of the motor and had to rebuild the tranny? That seems to contradict the "held up fine" statement in this thread? It also seems that you've picked up an extra 70 hp since that post. Please explain?
I have not searched for or seen a source for upgraded AWD transmission parts that fit this car...a Bugatti's would undoubtedly hold up but the fit, availability and price might be a problem.
I'll let you know how my little adventure turns out in about a week. My sc just got in last Friday. My Chrysler shop had to pull the engine to put in my new cam so it has taken a little longer than planned. The new heads are on and hopefully by the end of the week the sc install will be completed. I will be starting at 6 psi...depending on how the car handles that I may add more boost but I'll take it one step at a time.
If the aftermarket claims are accurate I will be between 650-700 hp at the flywheel which probably means 500-550 at the wheels. From what I've heard and read there is a good chance that factory transmission will hold up with those numbers...but we shall see!
