So, I'm looking to build my motor for max power over 5,000 rpm, and it looks like the Cobra Jet is my best option. However, I have heard a lot of people around here raving about the GT350 IM. Does anyone here have experience with both? Why would you pick one over the other?

Word in the grapevine is that the next gen Ford V8 (replacing the coyote) is in fact going to be a twin turbo V8 displacing roughly 4 liters. Furthermore, except for special editions, there will be no naturally aspirated engines offered. The only possible diversion from this path would...

So, I've seen lately that a lot of members have gotten some pretty decent gains from E-85 tunes. In my continued search for the best naturally aspirated build, I have been wondering if the higher octane rating of E-85 would allow me to up my compression? If so, how much? 12:1? 12.5:1? 13:1?

So, I drive about 50/50 Highway/City and I'm currently averaging 20mpg on my 2016 GT Performance Pack Manual. I live in Houston, and most of my driving is in less than ideal traffic, including a considerable portion of the highway. I was wondering how this measures up to what other GT-PPS are...

I can't seem to find any information online regarding what kind of potential the GT350 heads have. I have seen some considerable gains can be had from porting the stock coyote heads, but the cost is as much or more than the GT350s. Does anyone have any info, flow numbers, or dyno results to...

So, the pretext for this question is a bit long winded, so I will ask it first and follow with the reason. Question: What parts/components do you think will be cross compatible between the current S550 and the upcoming refresh? Arduous, long explanation for asking: So, I arrived a bit late...

First things first, the intention of this thread is to give opinions on what how you think Ford will design the S650. Second, this is also a wishlist for things you want or don't want on the S650. Third, there are many expectations that drive a concept to fruition. I think it's safe...

So I've been scrounging around the interweb looking for any possible means necessary to improve my front/rear weight bias and I came across a thread from svtperfromance in 2014 where a BMR rep was showing off a prototype K-member for the S550. It would appear that it never surfaced. What...

So, I'm Installing an X-Pipe, axlebacks combo on my car. This is my first mod on my S550. First off, is it safe for me to do this by putting the rear end on jack stands with the front wheels chalked? Second, I know I am supposed to jack my car up on the pinch points forward and aft of the...

I've been looking for a decent hood, but the options the markets have to offer are uninspiring... to say the least. http://www.bmcextremecustoms.net/20mumoramair.html This "Mongoose" hood from BMC Xtreme Customs seems to be the only cohesive design worth considering, but I don't know...

I'm looking for a Borla S-type catback or axleback.

So I just picked up my first new car ever; an Oxford White 2016 GT PP. I'm looking to keep it under warranty, but I'd like a nice sounding exhaust. I won't be tuning it, so performance really isn't an issue. My question is how much of a difference does a cat back make vs an axle back in these...
