yea, ford has a 4.0 DOHC motor in ausralia I6, that can do about that, i think it made like 1000 hp. Considering the 3.8 was engineered more for minivans and ecnonoboxes more than a racing motors its impressive.
is the 2JZ the supra motor?
They've never broken a stock 3.8 ford yet, it has shitty cast iron rods, a very strong crank, and shity hypereutectic pistons. I'd like to see a 3.8 ford built to its fullest, we have some pretty nice supercharged ones, but supercharging has limitations, the turbo stuff is starting to come out finally.
The fasetst v6 mustang i know of currently is Mat Neuhearts 10.3 sec single turbo, older generation 3.8 (single intake runner and 1 intake port per cylander in the heads) It has built up internals and pushes 20 some psi, its automatic ofcourse. If he put in the split port heads and dual runner intake with the IMRCs (01+) it'd probably bust into the 9s easily. Justin is planning on building a fully built beast. Others do 4.2 strokers and superchargers, i believe matt had a 4.2 stroker. Its so easy to just throw in the 4.2 crank while they are putting in forged rods and pistons that just aobut everyone does it. I dont think there are any advantages to keeping it a 3.8 crank, unless you put in a forged supercoupe crank from the t-birds, i heard those arent that much stronger though.
To date no one with a proper tune has blown up a 3.8 block, or broke a 3.8 crank. rods and pistons are the only thing we have trouble with on the stock internals. They do make stud girdles and other block enforcing stuff as well. I'd say within a year there will be a 9 sec v6 mustang, and 8 and possibly 7s are probably the limit of the block hp wise, then you'd have to get a custom aftermarket block.
And to the GNX, the ford 3.8 is based on that motors designs, and the newest (last) rendition of the ford 3.8 block (technicly 3.9, just a refined 3.8, still 3800 CCs) is considered even stronger than the GNX block. GNXes have pushed over 1500 hp.
I am more of a fan of I6 motors, but ford refuses to put one in the mustang sadly.
My car will probably go with a centrifical supercharger when i get money, but i mgiht just get a turbo for it instead and run slower but still have the potential to do more. I figure 2500 dollars for the base 4.5 psi non fuel upgrade, stock tune turbo kit, that only gets you into the low 14s, high 13s, but with fuel injectors, fuel pump, new rear end and a dynotune i could get it into the 11s on the stock internals.
btw i think the v6 stang in the video was using 100 octane gas to prevent detonation since it was using the stock 9.35:1 compression ratio, relativiley high for 17 psi.
The motor is completely stock, its just coupled up to twin turbos and a few improvements in the drive train, like the rear end and the shift kit and the high stall converter. fuel injectors and fuel pump were also upgraded but thats no big deal.
my car stock did about 16.2 in the 1/4 mile, with a 480 dollar y pipe back exhaust system, 400 dollars in misc. things like roller rockers, chip, intake spacer and cold air intake i did a 15.48@ 89.48 mph, my tune on my automatic transmission needs adjusting because it misshifts, otherwise i'd probably do a 15.00-15.2, once i put on my x pipe, under drive pulley, and long tube headers, port match my intake manifold and get a bigger throttle body i should take it down to about a 14.4 n/a. Then its time to upgrade the suspension, new rear end, and a powerdyne. Then i'll be good for 12s and i will be officialy happy for a long time.
considering i spent 14,500 dollars for my car brand new in sept of 04, i am pretty happy with what it does, and deffinently satisified in its potential, 14,500 for any rwd sports car these days is cheap.
Insurance is a LOT cheaper than the GTes, gas is cheaper, i get about 30 mpg if i drive like grandma on the freeway at 70. GM pisses me off with their FWD GTP G6, that car would be insane rwd, 6 speed manual, n/a 240 hp v6 OHV. I'd also like to have seen the new eclipse rwd with that big v6 they through in it, coincidently 3.8 litres.
