Basic Bolt on 99 2v 4.6 V8 Mustang Gains 35 rwhp and 30 ft lbs of torque with Mafia Dyno Tuning

[Music] what is up guys Westpac with auto mafia racing today we got a 2 valve in the building this is a pi/2 valves to 2001 convertible we're gonna go ahead and put it on the dyno see what we can make we don't really know what tune is on it the owner just got it it seems to have full bolt ons but he doesn't even really know what's on it so we're gonna take a look we're gonna check it out we're gonna figure out what everything is doing on it and then we're gonna make some power so it is a 2 valve so who really knows but let's get it done so as you guys can see it's already evening time Suns going down you know what everything is looking good but we got the car on the dyno now and we're just waiting for his SCT device to update so it's one of the bad things about SCT doesn't like to update that fast and this thing had not been updated in a while apparently so it needed over 3,000 different updates that are updating down to the device so we're having to wait for that so while we're waiting I went the car strapped up the dyno is ready to go so fingers crossed everything goes well that the tuning device that x4 works hey ok and we'll move on from there but we're going to show you guys the car there you go guys there's a 2001 GT now we are working with full long tube headers it's got MSD coils aftermarket injectors an aftermarket MAF the BBK throttle body plenum a cold air intake over in the fender obviously we got some different sized tires and it probably has gears and we know it obviously has an exhaust system which is Magnaflow so we got our strapped down it doesn't sound too bad so we're gonna basically go for it I'm gonna strap it I'm gonna put an o2 sensor and wear one of the rears was going that way I can see what the car is actually you know how lean it is how rich it is and we'll get it tuned up correctly that way but she'll be good again fingers crossed we'll wait and see here I might have to check back in the morning once this thing finally finishes say good morning and it's up to the turtle guys my bad tortoise later dude so it is obviously the next morning guys and this et device took forever to update I tried it late last night and it didn't work so we went ahead and wrote a custom tune for it threw it onto his device forcefully and so now we're gonna go try and see if the car will actually take the tune um I don't know what the issue is with SCT sometimes they do this it's a knowing there's nothing wrong with the car per se that we think or know of yet so I'm gonna go ahead and try and see if it will connect if it doesn't he's gonna need a new tuning device we'll swap it and we'll get him done booyah guys it looks like it's working clearing the trouble codes which there won't be that's just though what it does download complete so we're gonna go ahead and do a stop pull on the car guys so this is how the car is come to us I'm gonna crank it up here and we're gonna do a pull and we'll see how that goes fingers crossed uh hopefully it makes like 200 horsepower maybe more I mean it might not even be a stock tune it might be a tune loaded on the car already so we don't really know but we got the wideband hooked up so this will help us be able to tell so we got a cranked up we let it warm up a little bit but it doesn't sound too bad we'll get it rolling on the dyno and let her warm up a temperature get that water temp nice and uh ready for a hit and then we'll make a hit these cars usually would come with about two hundred and fifty five horse from the factory at the crank so really anything over 200 horsepower should really be considered a pretty decently running vehicle let's do it let the temperature super she makes alright guys so we just did that pool oh hey Cody hey you heard that thing you're getting out of your car what do you think it made you say look at the look at the graph 228 guys you see that 228 horsepower and 273 foot-pounds of torque so honestly like I said guys anything over 200 is about to be expected this is a full bolt on two valve it is a p.i motor they change that up you know and Brown 99 and after then you got the P I motors so it's the performance then proved where they gained a little power so I think that might have been 265 then from the crank from the factory but either way if you guys saw that pool did you notice our air to fuel ratio it was stupid rich so we're gonna take care of this guy we're gonna lean it up to where it should be so that he is running just on the money and I think we're gonna get an easy I don't put my foot my mouth 10% so I think we can gain 25 30 horsepower I don't see why that's out of the question we're gonna aim for more obviously but hey that'll be a start let's load our tune-up and make a first run on our pool so here's a closer look guys so it did make 273 foot-pounds of torque so as you can see we started the run basically at 2500 rpm we jumped into it so the car is making decent torque that's not bad and it carries it out you know at about 4,500 and then it starts really dipping down so we will see where we can gain and we did hit a hard limiter so we will change that up let it Rev a little a little more and we'll see if we can increase that a horsepower so this is it on SAE that was a unloaded run so that was just using inertia we'll get it going but Leia 228 to 73 I think we can do better so we got our tune loaded on the car we're gonna go ahead and crank it up make up and see if we can do any better than 228 I better do better than 228 but it will be our first tune this is my face tune on this car so we'll see how much better it is and then we'll tweak it and tweak it and tweak it and so we're getting those good numbers like we want so let's make this thing right [Music] [Applause] oh wait healthier now I said I'm gonna be able to pull 25 horsepower pretty easily and I think we were gonna be able to do that so let's spend the numbers around so we just uploaded another tune guys this is probably going to be our final one on this tube valve we've done a couple of different revisions to it I think it's gonna run really good so Cody guesstimate what do you think we're gonna make on this pass mm made 250 and 293 I think so - so I'm hoping for three hundred foot-pounds of torque and I'm hoping for 255 to 260 out of the horsepower I'd be very very happy with that there's zero head work done it's not an NPI to pee I you know conversion it's just a bunch of simple mods to it just bolt on so anything over 250 I'm good with so let's run it [Music] [Music] awesome so we just get that last pull I'm stoked this thing is ready to hit the streets much smoother throughout the entire hour p.m. ban we didn't pick up a ton of power but we picked up what I wanted to we made two hundred and sixty 1.2 horsepower and we made three hundred point 1 foot-pounds of torque so that is awesome it's ready to get out of here we're gonna call the customer have them come pick it up we'll go take it on the street show them how much better this thing feels and he'll be happy and we'll get it on the road so we got the owner here driving guys he's never driven it with this much power basically what you can added like 25 to 40 horsepower for him so I think he's gonna like it we're gonna go on a little test drive we'll see his reaction when he gets on it in the room matter to Reverend Pamela to show you at one of these the other way then you get render all the way through to about 65 so you filled in here you know it no it's full power hands man it does sound way better it was so like I don't know it's trying to dial yeah never get out pulls up to the speed limit yeah all right well I'm excited man I bought this car off of Craigslist about a month ago yeah been running around having some fun a little doggish but my man here hooked it up on the dyno and she's ready to rip now yeah she's smoking him he had a little trouble keeping her straight when we launched it there for a minute because she broke the tires loose but she's definitely a little more of a Ripper now I have to convince him to get some nitrous system boosts to have some real fun but she's much faster than she was thanks for bringing her to us and uh enjoy that's fit yes sir take care thanks for watching guys make sure to LIKE share and subscribe and we'll see you next time [Music]
