Sorry man, I had a big long typed up response the other morning then I had to close my browser and lost it all! I'll try to keep it shorter (oops) but don't really know how it will benefit you. IMO I would lose the flowmasters, the 65mm TB, and the cobra intake. Here's why; unfortunately I still can't upload the jpgs but here's the quick raw version. This was a few years back with the old AFM cam. 3.73s, BBK equal length shorties through the complete exhaust that consisted of a flowtech h-pipe and 2 chamber 40 series FM's with 2.5" tails.
In street trim 303/336. Opened the race readies and got 317/346.
Jump forward to after that winter of upgrades. BBK LT's, BBK X-pipe, dynomax welded mufflers, 4.30 gears, and an aluminum flywheel. Through the complete exhaust again in street trim 310/334, now had I still been running the 3.73's and the heavier flywheel the #'s would have been more optimistic (yes I know they don't change the actual power).
I don't have race readies anymore and have not ran the car with open headers as I used to all the time, yet it had still gone quicker than any of my open header passes before, and absolutely quicker than when I ran events where I had to run through the fm's. (typically I would see a 1.5mph loss and nearly equivelent .15 ET loss through the FM's vs having the race readies open.
In reference to all of the above this was back when I was still running the AFM cam.
Now move forward to the custom cam and with all else the same (aside from a lot of re-tuning after the swap) it put down 329/353 in the same manner as it put down the 310/334, just the cam swap.
Now getting onto why the intake; with the old Typhoon U/L the car had gone a best of 113.91 and would average around 112, after the swap to the Explorer intake it has gone a best of 111, only 1 time if I recall, and averages mid 110's. This is with a stock high mileage Explorer long block that the P-heads haven't even been off of so if this intake can't support this up top I have a hard time believing it can efficiently support your higher flowing heads. I also have to say that my 1/8 mile traps haven't changed any measurable amount since the intake swap, however my 1/4 trap has. My reasoning is that in the front 1/2 of the track it doesn't see over 6k, meanwhile running it out the back 1/2 it's exceeding that 6k. For reference, the car had been 11.78 with the Typhoon and MT DR's, and in only the 2 events I've ran it's gone a best of 11.96 in NMRA Factory Stock trim with the Explorer intake and on BFG DR's. Remember, this is a stock Explorer long block, not a dedicated race engine...yet :icon_wink
The other thing I would have to ask is; are you still running a stock tune, and your #'s seem to be on with 90Supercharged being that you both have autos. Honestly I wouldn't even worry about the dyno #'s without knowing what it actually traps in the 1/4.
Hopefully some of this non proof-read, rushed, non-sense gibber jabber can be of some type of value, LOL
