holy crap!! ur gona have to meet me at the pavillions one saturday here shortly and show me this beast!
As long as weather holds out i'll be out at the pavilions this saturday (the 24th). Hoping to be around 4-5ish, depending on what time we can get everyone together for the drive up there.
Your power looks to me is being lost in the exhaust...smashed pipes (even ones designed that way) are power killers on a turbo car. Cats are power killers....and ALL chambered mufflers are power killers. Basically if you were to straighten all of your exhaust out, you should be able to look straight through it....turbos hate back pressure.
I had a custom turbo setup myself on my old 04GT. Twin T-61s...did alot of research into it all. Me and my dad built the setup from scratch....you can search my name and my threads and find some pics and info if you like.
Anyways good luck with your sick ride and keep us all updated with the progress
I doubt i'm losing much power in the exhaust. The stock manifolds have proven to make some decent power. I'm sure they are a bit restrictive, and i'd like to test them against some decent shorties some day, i can't imagine i'm losing much, especially at this power level.
After the stock manifolds everthing is custom. Running a true twin scroll system with plenty of pipe diameter to the turbo. After that it's a 4" downpipe into a 3.5" oval pipe. That oval pipe then splits into my 2.5" magnapack catback. The catback should be enough, with straight through mufflers. 3" would be ideal, but 2.5" should be good enough. Also, there are no cats on this setup.
While the 3.5" oval pipe is definitely more restrictive than a round pipe of the same diameter it shouldn't be much of an issue. If you look at the picture of the underside of my car you'll notice an exhaust dump. It's connected to a 60mm Tial Wastegate set to open at 2lbs of boost. Exhaust backpressure should be a non-issue.
All in all, i think i'm losing power in the tune and the fuel i'm running. Pump gas here in phoenix is pretty bad.
The tune is also quite rich and missing a degree or 2 of timing and at least 500rpm. The motor had about 100 miles on it for this tune. I think once we go back with some miles on the motor we should come back with some good numbers.
I don't think we'll make 600+, but that's fine for me. Traction on the street is questionable anyway. And i'll have a nice 750rwhp race gas tune to play with when i want to anyway.
Anyways, i'll definitely be posting here with the results of the new tune and any other developments.
i dont have the ARP2000's in mine, but they are rated a 1000 with them. i have the 8740arp's i think. 800hp crank.
I surely hope so. Manley rates the h-beam rods at 700 flywheel hp. There are definitely people who have made more, though.
I did talk to my engine builder who said that they've made over 800 at the wheels with the h-beams. It's a bit of a gamble either way. The manufacturer doesn't spec them for this kind of power and i'm on the edge of what the builder says they've made.
I doubt i'll have a problem (hopefully anyway), but some a little buffer would be nice.
