Buschur Racing's new 5 liter Mustang
A very short history to start this off. I started with V8's, many-many years ago. I happened into the Mitsubishi powered DSM's and the rest was history. I've never looked back and I've never had a regret in the path I chose. The DSM's were great to us/me and then came the EVO's which have been even better. I want to make it clear we are 100% committed to the Mitsubishi platform and are in now way getting out of it, I still have to go 8's in the BadBish/RS!! I have more testing coming up shortly with the RS actually.
I bought a new 2008 Shelby GT, 4.6L NA back in 2008. I bought it because the new Mustangs are just plain HOT looking. I love the car. I put a Whipple 550 HO kit on the car, we've developed some exhaust component and brake components for the cars. It was not my goal to sell parts for them, the parts were developed because the market lacked what I needed for my own car. This has been the case for everything we do though I guess, we build what needs to be built and not a bunch of crap that nobody needs.
We've dabbled in the SRT-4 stuff, built some private label Scion parts for another shop, been down the Subaru road a few times. None of it really appealed to me very long and without the passion I can't stick to something and promote it properly.
My '08 Mustang though, I like the car, I keep finding myself messing with something on it and want to do more and more. With the release of the new 5.0 Mustang and the poor sales of the EVOX's at the dealerships I thought it was time to do something else.
About two and half months ago I ordered a new 2011 5 liter. I wanted the most basic car I could get so I ordered the 300A package. 6 speed manual trans, and very few options, a 3.73 rear gear and limited slip along with Ford's front and rear fascia and SS grille. The grill eliminates the factory fog lights and the new lower fascia gives you a spot for two new smaller lights or the option to use Ford Racing's brake duct kit there. I will be adding the brake duct kit on mine.
Today I finally picked the car up from the dealer. I bought the Sterling Gray Metallic with the Charcoal black cloth seats. I do not like leather seats, never have. I requested that the dealer leave all the protective coverings on the entire interior of the car, I'm going to try to keep it spotless while we are working on it, hard to fully appreciate the interior with plastic on everything but I don't want the car trashed.
Here are some various pictures of the car Jarrod took for me today, some of his best work I think!
The drive home from the dealer was done with the traction control offThe first thing I noticed when I got in the car was the shifter, it is fantastic. My Shelby has a Hurst shifter in it that is extremely notchy. The shifter in the car is short and smooth as glass, shifting it fast is effortless. Driving the car sideways through 1st and 2nd gear around corners was extremely controllable, like I've come to expect from Mustangs. The power was good, I'm pretty spoiled driving the Evolution around that runs 9.0's but this car felt good. The build quality I am very happy with from initial impressions, nothing looks cheesy or out of place on or in the car.
As soon as we got it back to the shop we put it on the corner scales. I wanted to find out what we were starting with. The balance of the car is very good. I was actually shocked at how close it was.
Left front, 974 pounds
Right front, 962 pounds
Left rear, 830 pounds
Right rear, 828 pounds
It doesn't get much closer than that. Cross weight was 49.8%, it's no wonder the car has had great reviews for handling.
Total weight with an absolutely full tank of fuel was 3593 pounds. While it's no lightweight it's better than I expected.
Here's a picture of the car on the scales and a shot of the corner/total and cross weight information:
Something I'd like to note on the car. The chassis is not nearly as stiff as I am use to dealing with. An EVO you can place a jack behind the front tire and pick the entire car off the ground, nearly evenly, the chassis is very stiff in an EVO. When I attempted to jack the side of the car up on the Mustang I had the left front tire 6" off the ground and the rear tire was still sitting on the ground. I moved the jack and used the rear end and the front support to jack up the ends instead of doing it from the side. Not a big deal but this is certainly a place where the car can be approved for road racing and autocross, stiffening up the chassis.
After we pulled the car off the scales, with only 18 miles on the odometer we loaded it on the dyno. We did a few pulls, 3rd gear, 4th gear and then reviewed the information. I then went to the internet to see what other shops had made with stock 5.0's on other dyno's.
As usual I wasn't surprised to find out Mustang Dyno reads considerably lower than all the other dyno results I could find. One thing that did bother me though was the curve wasn't real smooth. I made a call to the dealership to ask what fuel they put in the car when the filled it...................87 octane. Well that's not good at all. That explains the power being down and the curve not being smooth. We will have to revisit the dyno when I run this tank of fuel out and put some 93 octane in it. For now though the numbers came in at 311 whp and 274 ft lbs. Yes, I know, that's LOW!!! I am sure part of it is from the fuel and the other side of it is our dyno reads low, it is factory calibrated and I refuse to play the dyno games that many other shops do and manipulate the dyno into reading higher. It's a tool to measure results with, that is what has to be kept in mind.
Here is the dyno sheet:
Here's a picture of where the car is going to spend a lot of time!
The plans are simple. Friday night, weather permitting, I will race the car in 100% stock form. Next week we are going to start our testing. You can expect full results and dyno sheets for each and every part we test and develop. We will start with the cat back and work our way forward to the front of the car. A new air filter and inlet will be built, headers and of course the car will get a tune. I'm going to put a set of good tires on the back of it, Mickey Thompson drag radials and then head back to the track.
I'm expecting to see some high 12's in bone stock form with me driving and I'm hoping our exhaust, filter and tune will put the car in the 11's, that is the goal anyway. Given the fact that my Shelby has gone a best of 11.91 at 120.66 mph, I don't think I can get the car to run in the 11's at less MPH than that, I'll give it my best shot but may need to put a real driver in the car.
After we get the results we are looking for from the basics the plan is to turbocharge the car.....because that's what we do! A low boost, quick spooling kit is in the plans and then over the winter we will add forged pistons/rods to the engine and turn up the boost.
My intentions are to build the "BadBish" in a Mustang platform. So a car I can drive and enjoy, road race, autocross and run 8's in in the 1/4 mile. For anyone not familiar with "BadBish" this is my other car:

Follow along and watch the progress as we attempt to build one bad ass 5.0!
