It's spreading

[@markpolacek7840]

Dirt motorsports are sad at this time because of the 2 inspirational people we just lost. As with anything that u are interested in it is always good to see it live. U may never know if the players may change. RIP. Scott, Eloy.

[@DuaneBall-s9f]

I just changed the muffler system on the family van. Put it out the side and then up! I get better traction on the on / off ramps ! :)

[@willwills3915]

Exhaust pipes were the norm in the 80s just like Silvas today

[@troyelliott5045]

Reminds me of the Karl Kinser era “ he could tape a turd on the hood and others would follow”.

[@buddhavb3616]

Was thinking the same thing.

[@revwillieb8029]

There was an interview with i believe Dave Despain,, was talking about Karl KInser and the win streak Steve was on,, and Despain( i think it was ) stated Karl could chain a telephone pole to the back of Steves car,, and ever sprint car in the pits the following race would have one also

[@jeffperry7971]

Dang. First Bloomquist and now Eloy. This is a bummer. R.I.P.

[@Luke_81]

I can see it keeping shock temps more consistent, possibly tire temps and maybe even some sort of aero benefit. Love to see the innovation.

[@jag92g]

Cali cars had turned up exhausts years back when they were running SuperTrapps, as you noted. Does it help, maybe but it seems more of a look here not over there situation. It might do more for keeping the suspension components/tire temperatures more consistent than potential down force but any additional down force would help. Larson dominated sprint car racing in the COVID era without them so maybe it just took Silva a little longer this season to get it going since Larson hasn't raced as much as prior years or at least as much the year he won almost every night. The NHRA has rules for the headers for the angle and other specs so there is some advantage. But, a nitro engine almost generates the same horsepower per cylinder that a sprint car generates per engine, so that is a lot of air going through the old flammable air pump so there is some positive effect.

[@Alebob911]

I was just getting to say that when I noticed your comment. Definitely not a new thing.

[@tcjohnson3437]

Exactly. They have been plagued by mechanical issues all year. Happens, it's racing. Once that got worked out, Larson just went straight back to being himself. Paul sets him up as neutral as possible, and let KL move it around. It's what he does.

[@trev3971]

The pipes may have a marginal effect on tire temps or aero, but their true purpose is to distract from the actual source of the performance gain.

[@rickcouches1022]

i’ve seen them do it in drag racing, where they turn the bull horns upside down to help bring the front end up and transfer weight to the rear end

[@RonF-t2g]

Has anyone thought Silva just tried this and when they won they didn’t dare change it even though it made no difference. They might not be superstitious, just a little stitious. 😂 Check photos of this car lately. They probably haven’t changed any decals either.

[@mitchell-wallisforce7859]

Everyone saying Silva's putting up smoke and mirrors and doin somethin else we can't see, but the benefits of flowing more gas underneath the wing are there. With those massive endplates, it might result in an effect similar to a blown diffuser, if weaker. The exhaust gases would accelerate airflow under the wing, improving downforce and possibly doing something to quell wake turbulence by filling the air pocket left behind the car. That all said, they are pointed away from the main body of the car, so it might be something else. Then again, someone mentioned another team doing this but being forced to change the setup because the tips pointed towards the cockpit, so that might just be mandatory.

[@timg7627]

Yep. Thats exactly what Ive been saying. I think it produces less drag off the wing, specifically in dirty air.

[@michaelvickers1202]

100% all modern race cars and motorcycles use exhaust flow for drag reduction Kenny Weld had amazing aerodynamic Sprint car wing technology in the 80s and forward headers assisting flow check his cars out.

[@unclemuir]

The length of the exhaust header can improve performance. This allows for as longer exhaust as the tires would be in the way.

[@Pbeats100]

Great tribute

[@HTF10_4TW]

Using the ol air pump to its full potential. Several ways to do that through down force, air management off the tires and out the back.

[@mhinman2]

I wonder if the turned up exhaust doesn’t heat up the left rear tire as much.

[@rogermccluskey2227]

Thanks Justin

[@blacksheepexpedition6347]

Exhaust up =Aero.

[@kend6232]

I wonder what the temp difference is or does it get ameliorated at speed. I don't know enough about the aero part, but I've always thought that where the pipes were directed was poor for temperature control, especially when you're using bleeders for consistency on tires, ,might impact rear brakes less so, but I'm sure its measurable.

[@mattwuertz9102]

This has been a thing in drag racing for decades.

I have been told that the exhaust on top fuel dragsters and fc have been analyzed and are aimed purposefully to provide assistance in propelling the car?

[@Trackratz-zl9di]

Its all about the pipes " Brad Francis"

[@Thumper68]

You’re going to gain a little power with 18”or so after headers and keep heat off of the tires.

[@RegularJoes]

I saw Silvas exhaust in person on Saturday, crazy looking. I'm just guessing but wonder if it creates more torque. RIP ELOY

[@laudarevsonhunt]

Does nothing finished 11th in the B main.

[@RegularJoes]

​@laudarevsonhunt just curious, are you basing that off of Jocks result? Or have you run them on your car?

[@bigbadbrad354]

its 100% for aero effects. Doing nothing for horse power. Moving more air over the rear tires = downforce

[@laudarevsonhunt]

@@RegularJoes Everyone in Ca ran it that way in the 80's and 90's. It might be better to keep heat away from the shocks but not enough to turn a fourth place car into a winner. You need Larson for that.

[@RCRWJR]

​@RegularJoes It does nothing I turned up the exhaust on my Go-Kart and still finished in the back I'm switching Back

[@MuttTheBuckeyeSlayer1977]

I know him from you!!! Sad!! Good stuff as usual!!!

[@ChrisWigal-qn6lh]

Less heat on rear tires and parts. May help a LITTLE with traction - down force

[@strumbum946]

Maybe turned-up exhaust diverts heat away from the fuel cell. Cooler fuel = more horsepower. Just a thought…

[@NicoleSignorCreative]

It takes heat off the shocks....

[@strumbum946]

@@NicoleSignorCreative - Yes, and the tires and the brake rotors/pads/fluid. Does taking the heat away help anything? Seems like it wouldn’t hurt.

[@davidcologgi7397]

​@strumbum946 the rear rotor on a sprint car isn't on the wheel. It's inboard, mounted on the axle.

[@johncarter1137]

The turned up exhaust has to add a little down force, but is it enough to make a difference?

[@michaelloomer9851]

My vote (as a non racer/mechanic/engineer) is that it’s smoke and mirrors. Because that’s the kinda shenanigans I’d do just to mess with people and watch who hops on board.

[@sprintcarfan87]

I agree.

[@GameJunky513]

100%

[@JimmyJolly-d8v]

Paul is probably found something else he don't want others to see so he gets their attention focused on the headers and they miss what he doesn't want them to see

[@GameJunky513]

@user-nu7tt3hj8f people are just overlooking the fact that over this stretch these are tracks Kyle has already been good at in the past. I'd be more impressed and think they found something if he had a stretch like this on tracks he's been bad at.

[@DG-mp6xj]

If this was anyone else all of sudden winning races it might mean something but this is Kyle Larson who could win every remaining race he enters and it would not be a surprise. We are seeing a racecar driver that doesn't come along everyday.

[@jasongardner4686]

lol! The turned up pipes are a distraction for something else that is different or illegal with that car.

[@RCsportflyer22]

Pretty sure after the Thursday Tulare race dom and Rico took them off for Hanford.

[@jaydish3047]

Can we stop talking about this? These were super popular in the 80's and early 90's. We still have a set of them rusting behind the shop, I bet your mind would be blown if I told you they were supertrap's too.

[@NicoleSignorCreative]

With how consistent every car is (motor, set up, etc.) now, teams have to try things outside of the box, so of course other teams are going to try it. I'm not surprised. But yes, while it's "different", it's nothing new..

[@barneygeorge9588]

WOW!!!! y'all just figure that out? The 'turned up exhaust" DOES serve a purpose. Ever wonder why the nitro drag cars always have them turned up? It's so the exhaust from the engine when the throttle is fully mashed, pushes down on the chassis causing more down force as a result when the car is exiting the turn the driver hits the throttle increasing rpms and the exhaust pushes down on the chassis causing the rear wheels to grip so they can launch quicker on turn exit. This has been done for so many years but was done away with as the exhaust being vented was causing issues with other drivers, they used the excuse of 'to quite down the cars for the fans as fans were complaining about the loud exhaust noise', as such a rule was never implemented to stop teams from doing so. Old school making a comeback. 😊😅😂

[@racer44x]

Turned up exhaust only works when you have best driver in the land behind the wheel

[@KINGLOWNESS]

Potentially adding just enough backpressure to increase HP

[@88jhoyle]

backpressure is a myth

[@thedr309]

you talking about the headers like its a new thing, hell i know in the 80's at Ascot Park had all kinds of them, Joe Fontana had a super trap on the end and it turned up so much drivers ccould warm their hand over a flame on a cool night, Marty Madden had some odd balls as well, this aint new.

[@frankt2429]

[@NicoleSignorCreative]

Matt Campbell has been fast at Lincoln, with or without the change in headers - in 2024.

[@nathangannon5933]

Seems all the muffler turned up or down discounts that Larson is a real wheelman and knows how to win.

It's a head game. It freaks out crew guys who are looking for any advantage. It freaks out drivers on track because the car sounds different and where the sound comes from is different.
