On top of that the 3.7 V6 is a even firing engine meaning cylinder scavenging in the exhaust isn’t a big deal.

I don’t understand why Toyota and Fords Powerboost hybrid designs (I’m sure there are other manufacturers) and other similar technology is not the next wave of the near future. What is up with the complete jump to all electric when the U.S. infrastructure doesn’t even exist.

Yes I had to drill, tap and install the fitting on each turbo, but this is the best source of line pressure with a internal wastegate, right off the compressor housing. Also after you get your overboost issue sorted out you will probably want to buy a might vac vacuum/pressure gauge (not just...

I use the turbosmart IWG only, no boost controller on my 3.7 ecoboost kit. I use a 7 psi spring, use a mighty vac to set the preload and total boost 10 psi on 93 octane. My wot pulls at full boost is 10 psi throughout the entire powerband to 7k rpms (starting at 2750 rpms). I’ve never got any...

Best way to set preload dead nuts on manual internal wastegates is to use a mighty vac that does both vacuum and pressure.

Me, my wife and daughter all have student debt and I still think this is a bad idea. This will be the first step in the Democratic Party wanting to offer free college for everyone. Most Democrats are very delusional when it comes to all this great free policies that they want. Someone has to pay...

Did exactly that (except I have a 13’) and have 3.55 gears and no traction. It’s not the whp that makes the ecoboost swap so fun, it’s the 450+ wtq starting low in the rpm band.

Thought about doing CDC upper and lower with mesh on my car also but don’t know if it would offer a significant increase in airflow over the Roush upper and lower.

3.7 V6 crowd ran the DNA shorty version for years. I personally had a set and compared to my BBK shortys. The DNA motoring was an exact copy of BBK but they (DNA) used SS flanges vs. the BBK steel flanges and had better welds then the BBK set I had. Throughout the years BBK vs. DNA motoring has...

^^^^ Ignore this asshat. I guess he doesn’t know that the 2005-2010 GT 4.6 3 valve made as much power as the 3.7 V6 does or he’s just a hater. Yes a aftermarket tune like MPT will remove the factory safety feature.

Unless one of the 3.7 V6 owners has a 3.8 V6 now or prior experience with the 3.8 V6, your probably going to need a 3.8 V6 page or forum.

Any catless downpipe on a turbo setup is going to see great gains. Catless downpipe is considered one of the major upgrades on turbo powered vehicles.

Going catless is the biggest thing you can do for FI car as far as stock exhaust, outside of going bigger exhaust on ANY FI car.

If your out of warranty no. Just make sure to tell the dealer if they do work to not flash your computer..

Ha, try having a 3.7 V6 model. You get the normal slight remarks or shit talking, until you beat them or they find out you have twin turbos. Funny how turbo anything automatically gives you a pass even if you don’t race them I had a guy at Hooters show one time pop off the mouth about his 4.6...

I’ve read the 2.0 Focus ST block is better then the 2.3 EB block. So I would probably build one of those for ease. 3.5 is going to be a lot of work and more money.

It’s been done on a 3.7 V6 mustang and it still wasn’t cheap. 3.7 engine is basically a bored out 3.5 like the F150 3.5 EB, but the 3.7 has port injection and few other changes engine wise.

Pretty sure it’s true, the guy came in on the Facebook page that I’m on and posted it up right after he found it the note and shit in his exhaust. Good luck getting in my yard or to my car. I have Dobermans and guns, although I might just taser your ass and beat you up over and over while...

If those are your choices, GT.
