Stage 4 - 2006 mustang gt project grabber boost - Americanmuscle

Hey, Dave here and welcome back to stage 4 of our project car known as Project Grabber Boost, if you've been following along up to this point you'll know that our goal was to create a 3 valve that can take down our '14 Coyote powered GT at the track, and be a well rounded street machine. It's now to the point where we're going to show Justin and his team what our 4.6 can do under pressure so to speak, before we do that, let's recap the supporting mods we did in stage 3. In stage 3 we made sure our 3 valve was ready to move all the extra air when it came time to crank up the boost in stage 4. For starters, we replaced the restrictive cast iron factory headers and mid pipe with a quality set of long tubes from Kooks, along with their matching off road x pipe. To help us get the power to the ground, we installed Exedy's Mach 500 stage 3 clutch, and a lightweight aluminum racing flywheel, and the drivetrain, using Driveshaft Shop's lightweight aluminum one piece driveshaft. Finally we topped our 5 speed trans off with a Hurst billet competition plus shifter which should eliminate any possibility of a miss shift when we line up on the track against the '14. Alright, we know you guys have been dying to see what we have done, so let's show you. We went with the Vortech V3 SI trim blower to give our Project car the boost it needs to live up to its name, the V3 is an internally lubricated centrifugal supercharger, it's a real good blower for the street or the strip, should produce some good psi, and give us some real good horsepower numbers to compete against, and run with the 14 GT. Of course when you're doing something like this, you can't expect to just slap the blower on and go, there's a few extra changes you have to make to the motor to let it accept the extra air you're forcing into it. Mike: So for starters you've got to take a look at the factory mass air flow sensor, it's just not going to be able to keep up, so we're keeping things simple, we went with a plug and play unit from DiabloSport called the MAFia, it's a piggyback unit, goes in line with your factory MAF, but it's going to allow it to handle all the forced air from the supercharger without spiking the unit. Steph: But maybe the most important part when adding forced induction, other than making sure you have a good tune, is making sure you have enough fuel to meet the demands of the new setup. So in order to meet our increased fuel needs, we added two parts from Ford Racing, We installed Ford Racing's high performance dual fuel pump kit, and paired that with Ford Racing's 39 lb injectors. In order to avoid detonation, we also installed a colder range set of spark plugs. Dave: Well that should do it, in fact that does do it for our Project car here, before we head down to the track why don't we get the car over to the dyno one more time, get one more set of numbers and see what we made. At the end of stage 3, Grabber Boost put down 301 horsepower, and 316 ft/lbs of torque. Well, here at the end of stage 4, we just blew that away, putting down an incredible 463 horsepower and 425 ft/lbs of torque, that gives us a peak horsepower gain of 153, and curve gains of 172 horsepower, and 147 ft/lbs of torque. The car looks great, it sounds great, the horsepower numbers are amazing, and I think we all agree, we've got a real fighting chance against the '14 GT. Ready for the track? Let's do it. Dave: We're back down here at the track for the final showdown, as you can see Justin and I brought both teams, Project Grabber Boost, and Project Coyote, it's going to be a great day. Justin: That's right man, it's best of 3, showdown, we've had a long road with these cars we've spent a lot of time building them up, but I think the end results are great, you're making over 400 horsepower with 10 lbs of boost, we're making about 400 all motor, so all motor vs boost, we're making similar power, we should have a great race on our hands. Dave: I agree, it's best of 3 showdown correct? Justin: Best of 3 yes sir. Dave: That's the plan, so hey, you guys excited? All: Yes Justin: Alright let's get it on! We're going to tear them up man honestly. Laz: I don't know they're under pressure, I think we've got the motor for it, time will tell. Mike: We're going to be the victor. Steph: I'm worried about it hooking. Dave: It's a Mustang, you hook, you're going to win. Dave: That was a heck of a good run. Justin: Yeah, it was all launch for the 14. Dave: We're going to hope for a little more tire smoke and see if we can't get the power to the floor because this could be close but great run. Justin: Well as you can see, we had our first real issue down here at the track, a litte sad, a little scary but luckily we kept it off the wall, we actually broke an axle or something like that coming out of the 8th mile and cut a tire, not too pretty but either way we did manage a best of 11.9 on our first run not too bad you guys got a 12.3 in the books, so I think what we're going to do just to keep it fair we're going to let the 06 run one more time, do you think you guys maybe could take down that 11.9? Dave: It's our goal, certainly, we've got the power, so let's give it a go, get out on the track, let's go try it. Justin: Get things cleaned up and patched up and we'll see how we do. If you want us to sign your shirt, you know "Grabber Boost", you know? Justin: Well, what a day racing huh, we've had a car almost hit the wall, we've had a couple of 11 second passes, as hard as it is for me to say congrats on your win guys you definitely earned it, alright man. Dave: Thanks man, congrats everyone behind me, it was a really great just getting out Project Grabber Boost, going against Project Coyote, we had a 13.5 last time we were here, and we dropped it all the way down 11.6. Steph: There's more in there! Dave: I admit you guys had a good run too. Justin: we had a great run, 11.9 down from a 12.5 last time on our first run, still think the car has more in it personally but that's not the case, we broke, we lost fair and square, we admit that, but we are going to fix this beast, we're going to come back, and see what we can really do. Dave: Well it's good, honestly, it was great watching and being a part of it so, thanks for watching, congrats to Justin.
