Does Air-Box Lid Removal Actually Work??? | 2020 Shelby GT500 Mustang | VMP Project SnowbirdFeb 27, 2020
hey guys this is Syd with quiet SPT performance and as we promised at the beginning of a week we have this new
gt500that VMP performance has been playing around with it has the ported fan from their Joker and some soft tweaks but no a lot more but as we promised you before I know you guys saw the ridiculous gains we were making just by removing the airbox cover on the dyno you know we're getting like 50 60 horsepower out of this thing that was crazy just removing this little plastic cap and of course we were doing that on the dyno with the hood up when we closed the hood we were losing some power so what better way to test it than to take it to the drag strip and run it from cap to cap to see if there really are any performance advantages or disadvantages to running it one way or another.
I have a theory. I think it will
workbetter with the lid on, but we'll see, so we've done a few different runs throughout the day and now it's kind of time to get thi out. The airbox lid is off, so obviously we've already unbolted it you guys saw we made some pretty ridiculous gains with this thing removed on the dyno so as we mentioned before it was with the hood down the gains disappeared so now we'll try it on the track and obviously we won't be trying it on the track with the hood up so it will be closed but my theory is that removing the cover can affect track performance and that's because if we put this cover back here it seals pretty well you'll see that Ford put some foam here and the ring here sits like a groove which makes a pretty decent seal around this thing and the reason I think it seals pretty well is because Ford spent a lot of time and money down here in the front of this car putting this nice little shovel and if you look in the back of this thing you can see the filter and this thing is pretty big I mean you can see it's taking up the whole corner from the grille basically what we have here is a factory built ram air intake and i have a feeling the ram air effect will go into this filter.

This box must be closed; otherwise, the air that comes in here is going to go all out. over the engine compartment and is not used properly with the cover on. I feel like we're going to force cold air into this box at speed because you know the Wisk is tying up 130+ miles per hour so a lot of air is coming in. pushed in this airbox there's only one way to find out remove the lid close the hood let's go down the track let's see what you do so you can see the sunset we're getting ready to run with the airbox lid at home It really did please you i give every possible advantage with this setup because it's down probably seven or eight degrees a nice breeze isn't too bad it's probably 82 earlier today it's probably 74 so now it's a good night so if this
works out significantly more quick we'll know the game we were looking at on the dyno and play it in real life it runs at the same speed or slower you probably just want to leave the airbox cover on for now start playing with the pulleys. it's plus 100 and 100 plus millimeter throttle body but at the end of the day just a 93 octane fit pretty smooth fit on this car not very aggressive and of course no transmission fit right now these I can't even register what's going on in the transmission so we found that raising the rev limiter and then manual shifting has been giving the best tops that's a super clean run ten eight 131 miles per hour that's the fastest time he's ever run the day but how much of that was the air temperature.
You think you know it's 60 feet slower, and from previous experience, it's hot air being sucked out of the engine bay at launch. on the track and eah it's not a real world comparison it's really not a real world mod you'd want to do at least at this power level yeah we had power that's what I was thinking you know if we threw one at it pulley and we start doing 20lbs of boost where that blower port should really start to shine at that point maybe Rams picking the fronds
doesn't really matter much of course not given by ear it might be more of a benefit of restriction, but so far it seems like it likes taking that fresh air in from the outside in and not sucking heat under the hood.
The Aryan cable did a good job with the cold air from your factory, so that's the challenge it's been given. and later markets are going to have to come up to deal with it if they're going to update that part we need to just find a filter and put it in and see what it
doeswith just a filter i mean there may be a bit of a restriction on paper filters to possibly pick something up there it might be and i think the gt350 filter will fit that air box too well maybe that's something else we can test later on one thing for sure it's definitely not making 50 more horsepower , not in the real world, so we'll have to be careful what the guys say about cold air. dyno especially put dyno racing going because we've shown you can do a ridiculous number if you want to do enough that's basically it but in the real world it doesn't translate to real performance yeah definitely so now just for the sake of being thorough.
I'm going to put the air box back on right after the race. I mean, this is still very hot. Replace the airbox cover and let's cool the car down. maybe an eight degrees a little bit but this race this race with the cap all he lost a little bit in the 60 foot time he wasn't faster he was running basically the same time and he picked up maybe a mile yeah and that could be very easily attributed to whipping around a little bit later in the day yeah so we're going to let this slide again and now it's a little bit more cold air so I've had about a 20 minute cool down since the Last time I ran with the airbox lid off both the airbox lid is back to similar temps to last race and we'll see what it does this time the only thing that changed was find a parameter in tune it allows you to use launch control with traction control off so let's test that that's the thing with tuning these cars it's basically in its infancy a lot of parameters are not defined in software yet of tuning and not we have no access to the transmission control module so we're really just testing stuff here so that's a setting we've changed between the two runs just to see what it does other than that spark fuel everything else It's the same except that setup change and putting the airbox cover back on for the last time the car did a 1087 one hundred thirteen ty-one miles per hour with the airbox cover off, so with her again look what she does by the way we lost 60 feet of time last time with the airbox cover off which is a classic sign 1084 130 point eight next we headed back to the bench testing and it's all a cold air intake prototype from the JLT performance
