Maybe he wants that rumble that you simple can't get with a V6.

Vortech V1 supercharger with 2.87 pulley(17lbs of boost)

Those numbers seem a bit low especially with a bascially intercooled vortech setup at 17lbs of boost.I would of figured from what i have seen you would be beyond 350 and almost near 370 hp area especially with port and polished heads and intakes and a bad ass flowing exhaust. A bone stock splitport with a vortech unintercooled at 6-8 psi makes near 230 hp. add the injection your close to 270 rwhp and the boost and heads should put you at 350. What kind of dyno was used? How are you geared?

The limitation is inlet air temperature. the Water injection isnt enough to bring the temps down where they need to be to add enough timing. If I install a water to air set up im sure i could hit those kind of numbers.

4.10 gears on a Dynojet

not worth it, its alot cheaper to build up the V-6 if you know what you are doing

super six motor sports
tma turbo
VMP tuning
look at junkyards for an M-90 supercoupe motor

its very easy to do a turbo build up on fords essex 3.8, basically its a modified copy of buicks grand national motor, and have you ever heard its a waste of time to build a turbo buick? didnt think so

fords 2V mod motor is a peice of garbage, dont bother with it

99 mustang gt 35th vert - bolt ons
09 f-350 lariat CCSB 5.4 - DD
04 f-350 RCLB 6.0 - sold
---8100 lbs 13.9 @ 96 tune/deleted, stock heads

Yes because there are so many 2v that make the 3.8 look fast.

Honestly now.

I give props to V6 convertible, those are some decent numbers, but at the cost of 17 pounds of boost.

A 2v swap should not cost 5 grand. More like $2,500 max if you shop around.

I would have bought one of the two cars listed below had I not already gotten a killer deal on a complete engine with all the wiring.

Here are two donor cars that I was watching on ebay:
http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT

http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT

Not to mention that you can sell off extra body parts thus lowering your cost even more.
For us pre 99 v6s who have 150hp vs same year GT's 225 makes it a 75hp upgrade.

That means adding 100hp to your V6 at 5 grand is $50 per hp
The 1 grand V8 swap comes in at $13 per hp

Now that wrecked GT's have come way down in price it is way more cost effective to swap IF you do it right.

Snow kit $300
Sct chip and tune $400

What you have done is pretty impressive.

However red97mustang asked about a v8 swap. Everyone made it seem impossible or crazy expensive like 5k. There are several ways to make power and I just wanted to give the info I had that a v8 swap is a viable option.

red97mustang: Check 3.8mustang for more info. I've posted several times about wiring changes that need to be made. That's sort of my specialty.

Wrong, I responded to you insulting the 2valve modular motor, because according to you it is, what, inferior? Now WHILE the best bang for the buck MIGHT be to supercharger the V6, that is besides my post. All I did was defend the motor because, it isn't a piece of sh*t. As for best bang for the buck, yeah supercharge the V6 if you want to have to use 17 psi just to obtain 300rwhp, or you could swap in the V8, find a used 8psi supercharger for about 1k or so, and have quite a bit more power, with less than half the boost.
