    I've been to Streets of Willow, Palmer, New Jersey Motorsports Park, Thompson, and Lime Rock Park. I'd like to move into NASA time trials some day but for the time being I am quite happy just enjoying the hobby.

    I plan to do some aero mods, such as a splitter, diffuser, and possibly a wing. My biggest debate is what to do with the engine. I do enjoy having a nice, reliable motor even if it's not the fastest, so I may just do some bolt-ons to get a little more oomph, but forced induction (and supporting mods) or a Coyote swap aren't out of the question. I'm wary of the extra weight, cooling, and fuel needs that come with supercharging and the expense of a Coyote swap makes it a turn-off, which is why I may just stick with some nice bolt-ons. Any thoughts?

    Looking good so far! Cutting metal is always intimidating :)

    That's a great looking build and welcome to TMO. Good luck with the time trials and guys like @ArizonaBOSS have a lot of knowledge to share.

    Fun build. Looks like we shop in some of the same places!

    Too bad he's already got his car setup nicely because you know how we like to spend OPM! @Grant 302

    Thanks everyone. I am very happy with how it handles. I've been focusing on seat time but that cracked wheel has made me pause until I can get my replacements in.

    Nice car, I'm kind of heading in the same direction with mine, but lower end spec parts. Mine has 19x10 SVE wheels with 285/35R19 Tires. Yours is the second mention I've seen of Forgestars cracking, I'm glad I didn't go with them.

    I don't see a brake upgrade in your list of mods, so if you're interested this is how I upgraded mine to 14" front rotors with 4 pot brembos in the front and 13.8" rotors in the rear: https://mustangforums.com/forum/200...for-those-who-think-they-can-t-afford-it.html

    Those wheels were pretty well abused during their time so I don't think it's a brand-specific issue.

    I have the four piston Brembos, stainless steel lines, better fluid and pads up front. Haven't done much with the rears except stainless steel lines.

    Aside from the expense, the Coyote is pretty reliable and fire-and-forget. You can have 380whp (stock) all the way to 460whp with just intake/TB/headers and competent tuning--and no blower/intercooler weight up front.

    I have to agree, if you're up for the swap, a coyote is the way to go.

    That's kind of what I figured. Scavenging salvage parts may help bring some of the cost down. Is anything required for the dash or does a kit cover that too?

    Nice work, Chris! I don't see the 'need' for the engine swap or power upgrades...Slicks, wheels and track consumables are all that's 'needed'. What tires are going on the 18x11s?

    Thanks!

    I don't have a need for anything other than seat time. I start planning things years in advance though so I can save up the cash for them. The car significantly outperforms my driving ability. Same for the tires. The wheels will come before anything else is done. I am going to be spending a couple years overseas with no vehicles so it's much too early to say what I'll be getting. I just picked up some GT500 wheels in order to be able to even drive the car and store it.

    I'd sell it for a 12-14 GT but the car is paid off and the mods are worth more than the car is. I don't want another car payment now that I've got basically zero debt. I'm cheap like that.

    Edit: as an addendum, the engine modifications will follow whatever time trial class I end up running in when the time comes. I would hate to accidentally bump myself up a class and be non-competitive or end up having to spend way more money than I'm willing to shell out.

    Sounds like you have your addiction under control. That's a good thing.

    As for the NA 3V build, I have taken my car about as far as I can go NA and on pump gas with the exception of compression (I'm 10.2:1). Dyno tune yielded 417whp, which is easily attainable with a Coyote for much less coin. There is no substitute for being able to control the intake and exhaust valves independently, as they are on the 4 cam Coyote. On the other hand, 3V motors have shown that even though they don't suck (NA), they swallow (FI). Going FI will wake up a 3V, and the power limits on a built motor are well above usable for a track car. Hence the reason I didn't go 'all in' with 12:1 compression. As you know, the weight penalty sucks, but it can be dealt with if you have mad skills like Fabman.

    Holy cow, 417whp? What have you done to get that, just out of curiosity?

    At that power level, I can definitely see where a Coyote swap would be more cost effective. Depending on the class restrictions, I'd be aiming for something more like a 10:1 power/weight ratio. The car weighed in at around 3470 without me in it (3640 with me in it) and most of the interior still intact, so I wouldn't be shooting for those numbers. I'm quite sure I could get around 340-360whp no problem, with a little room to go lower or higher. Like you said though, maybe it's easier to detune/tune the Coyote to be able to meet different class restrictions? I will also have to be considering aero mods as well, so who knows where this thing will end up.

    Of course, in three years a Coyote swap may be a lot cheaper so this all might be a moot point!

    Some days I want to just say screw the classing and build it however I want it to play with it. A lot of my track friends seem to find this more of a job than a hobby trying to keep up and I'd prefer to keep it fun.

    I'll start a build thread on TMO tonight to document my current build. Time will be your friend on the motor swap. The Coyote crowd now has Voodoo envy, so prices will come down as availability remains high.

    Well, I'll tell ya....
    I made 700 rwhp with my stroked and blown 3 valve and it flat hauls the mail.
    BUT, it cost a mint to do it. The Coyote motor came out just as I was finishing my build.
    Lousey timing, I know. I spent 4000.00 on a killer set of stage 3 CNC ported heads that are as awesome as they come.....and they don't flow all that much more than a set of stock Coyote heads. :( That's how much better a Coyote is.
    If you want to make any real horsepower, the smart money is on the Coyote.
    Also, the Coyote will live longer. A modified 3V is on the edge around 450 rwhp. After that you need a built short block which will send the cost up over a new Coyote motor from Ford. I love my 3V but, they are obsolete. Besides, who in their right mind needs a 700 hp track day car....? ;)
