Best place to buy a coyote+tko600 ?

[Paquette173]

Hey guys, ordered my kit this week. I want to get as much parts that i can get before the kits gets here.

At first i wanted a used engine but the crate engine doesn't cost alot more.

I'm looking for a combo or something easy/good price to order. I'm aiming in the near future adding a supercharger to get 580-600whp. Think the tko will hold up ? I will only drag it 2-3 times in the summer but will be lapping the car alot. What supercharger will fit in the mark4 ? Vortech, procharger ext...

I saw summit racing haves a complet package for the engine a bit under 10k. All i need then is tranny, bell housing and clutch. What combo of clutch i need to hold the power of the supercharger and will be "street friendly".

Theres other venders that sales engine and tranny, where is the best place and price to buy ?

Also i'm taking the 2015 IRS, most people run 3.55 but theres a package for 3.73 with the torsen. Is the torsen worth the extra pennys ?

Thank you guys your your help!

There are a few vendors that seem to be best for FFR complete engine trans packages. Forte Parts Connection & Levy Racing are builders & dealers with excellent reputations either of whom I would have used coming in cold. I got my package from Summit Racing because of prior dealing going back many years. Also got the TKO-600 & clutch package from them. Was in the $11K range all in back in Dec 2013.

I've not seen anyone on either forum doing a Coyote with a supercharger. So I don't think you're going to get any responses from actual experience. The Mustang guys are doing this, and there appear to be several options. With a supercharger in your future, does it make sense to consider something other than the stock Coyote? Like the Aluminator, for example? I personally don't get trying for this much power, but OK. The TKO is rated for 600/600, and it's quite strong. Should handle the power. You may want to do some checking on the 2015 IRS though. Guys running that much power with Mustangs are snapping axles and doing other mods to handle it. The Torsen setup is the most performance oriented. Do some research to see if it's best for your setup though. I don't think 3.73 is the right ratio for what you're describing. Use an on-line calculator to find what would be best. The Torsen piece can be put it any of the 2015 diffs. Just only comes from the factory in the 3.73. What what you're describing, I would only use the cast iron diff.

As far as where to buy your stuff? I love Summit, and use them all the time. I'll be buying a Coyote for my latest build in the next few weeks. Their Coyote package is OK I guess, but you can save money elsewhere and also get free shipping. Summit doesn't provide any value add IMO. They just crate up all the parts. Forte's will give you a package deal and do whatever assembly/preparation you would like. He is also a distributor for Tremec, and knows what it takes to install them in these cars. Plus is available for support after if that's important to you. I don't know that Gordon Levy does Coyotes. Haven't seen it.

Forte or Levy are likely your two best choices. Both are very knowledgeable and won't steer you wrong.

Lots of new buyers want more HP when they start building but the owners driving them say anything over 400 HP is a waste especially on the streets. The car will spin its wheels at will in the first several gears. I would suspect your biggest problem will be dialing in the chassis to get that 400+ HP to the ground. Check out this thread (http://www.ffcars.com/forums/17-factory-five-roadsters/487529-wild-street-challenge-build-625hp-coyote-itbs.html) on what a builder is doing to get 600+ HP (Coyote) to the ground. It also has some info on the clutch he is using. From reports of other builders the aero on the car in factory form is a little unstable over 100+ MPH because the front end gets light and starts to dance around. If you are certain you want to get to 600 HP, you need to buy your kit with the 2015 IRS with front and rear sway bars. One of the advantages of these cars is the light weight and they will spin the tires when trying to load the power train with lots of HP. Parts that break on the heavier Mustangs will survive on this car.

I've used Engine Factory Inc. (www.fordcobraengines.com). Contact Chris at 1-800-704-5385.

I have a friend doing a Coyote and supercharger. He is going to have to have his hood customized to fit.
You may want to ask Factory Five what the new IRS will handle. The old version needed upgraded half shafts to take that much. He is also doing a RaceLogic traction control system to help it hook up.

I knew it was a matter of time before we'd see people with an interest in supercharging the Coyote. If you do continue on this route, I hope that you will share your experiences with us.

I'm not trying to talk you out of anything because these cars are very much about the dreams/fantasies of their owners and builders but I recently took my first ride in a Coyote powered Roadster and even with the standard engine, the car seemed to be on the very edge of being a balanced package. What was most surprising was how much more stout the Coyote felt in the Roadster than it does in a Mustang due to the dramatically improved power to weight ratio of the Roadster.
