Briggs Flathead Race Engine Dyno Test

[@alexhickey5633]

A very clean power delivery. Didnt sound pissed off or anything. Absolutely amazing, well done to ye

[@davidpassmorejr.5559]

We ran Cox, Dover Power, Gecker and Capps flathead engines from 05-08. Won with all but there was something about the Dover Power... I'd say the Capps came second behind the Dover. I wish flatheads were popular still; it's one reason why I'm not interested in getting back to karting again. I say bring those engines back and make karting great again! lol

[@speedracerw30]

Flatheads are definitely making a comeback now. If they would just bring back the animals too, I'd be happy.

[@ssssniperdog_7897]

Couldn’t agree more!! The sound the smell even eyes burning is irreplaceable

[@milwaukeebrewcrew484]

Still having fun with my mini bike with my 276cc 7hp flathead

[@aSpyIntheHaus]

That was the beastiest 0.35hp I have heard from a Briggs.

[@tylerfrankel5374]

That sounds extremely similar to a NASCAR I love it.

[@Chase_01]

STOCK car

[@mattloara8363]

I have one of these in great condition i got From BYE Racing fresh rebuilt runs on methonal M1 or m5 love it over a built honda The looks, the sound the power from a small engine

[@MJ-nl3pv]

Right

[@ephenj]

buddy built a small dirt oval behind his house his old bro runs a methanol flat head briggs whoops us all with the clone motors. Those flat heads make great power for smaller tracks.

[@DonovanBryant92]

not too bad going from 5 hp to 11 hp

[@ellisjackson336]

Odd how it starts to sound like a v8 in the higher rpms

[@pauljones9746]

Put a 4 hp head and a 3 hp flywheel on it, it''l kick it up a few more horses.

[@danielblaylock5566]

Ive done the 3hp flywheel with the adaptor for the coil......... Billit aluminum flywheel and the or dragster coil was a whole lot better but yes stock parts mixed together can work very good....... My nephew won a championship with that enginge and was tore down but they couldnt do anything about it because it wasn't stated in the rules.......

[@danielblaylock5566]

I got one.......... Fuck paying thousands from a lowball engine builder that over charges........ I have 500 dollars of actual parts that I bought but machined and assembled it ourselves........ My brother knife cut the crank and balanced it at the turbo shop he was running.... Shaved the head .125. Bored it .030 over..... Has a dynocam cam and springs.... We ported the intake and exhaust ports. Put billit aluminum flywheel with a briggs or dragster coil on it and an arc billit rod........ Stock carb converted to alcohol...... And it runs 9500 rpm all night long on a dirt track all for 500 bucks and not too much personal time also has a 4500rpm takeoff adjustable spring clutch.........it was half the cost of the engine........so 750$........I bet this engine in this video is 1500bucks......

[@chevyss1705]

so true.

[@cravenmoorehead5636]

And we'll worth it. Yours may have been fast but far from legal. That's the talent building a stock legal engine that will outrun yours. Talking big words won't make it faster. Also 750 for a cluth is a rip off.

[@alexpencek2172]

Have you ever tried the Briggs animal engine? I used to race microds in upstate ny and that’s what we used and it put out the same horse power

[@tannerlotito3313]

I’m trying to get my dads old kart running, what fuel you use? It runs on meth but not sure if that correct

[@harrisong5232]

Someone plz help is there any different carburetor for the Briggs 5 horse fun power engine that I can use? The stock one has so many linkages and it’s really tricky

[@kendalemcafee1306]

When u find out let me know with part numbers

[@PeelePowered]

I use a Tecumseh 6 horse carb on mine. You can also use the Honda/Predator 6.5hp carbs with adapters

[@harrisong5232]

@@PeelePowered dude thanks so much

[@redman715]

On alcohol?

What are the little red plastic things where the pull start would normally go called?? I’m looking for a purple one but can’t find them because I don’t know what there called. HELP!

[@Ben11789]

zqrf it’s a flywheel cover and they are metal. You can find them online

Yes. I have ran stock medium with a flatty against the clones and won, legally. I believe you could get more out of a clone or predator, they just dont sound and smell like a flatty.

[@mattloara8363]

Yes

[@deansova578]

@@d.bowman8032 I love Flathead motors I have a few.

its awesome how a flathea cant have that lots of rpm s

[@MrEric4555]

I’ve been trying to locate a raptor engine do y’all come across those alot?

[@Ben11789]

MrEric4555 yeah I race in upstate ny and it is mainly flatheads up here. Down south they usually race clones but they are common around where I race

[@MrEric4555]

If you ever come across any raptor engines message me I would be interested can’t find engines like that here in Houston

[@lowbudgetfilms2006]

@@MrEric4555 ive got 2 engines one stock briggs flathead and another racing flathead would probably part with them

[@OGbqze]

And now you could throw a header pipe and remove governer on a $120 predator 212 and make the same.

[@ebgarage]

These engines can make way more then a predator 212

[@allurared9029]

Yeah but predators are kind of an ugly looking engine imo and everyone does that. Its not how fast you go its how you go fast 😉

[@_..-.._..-.._]

Before anyone could afford the Japanese engines, these were all there was for decades. If you really dgaf just use a motorcycle engine…but see how that ruins the point of it all? Flatheads have a terrible time flowing air, so it makes it more competitive.

[@oaktreemrjo]

Still doing flat heads?

[@coltonberry9804]

Can someone tell me what fuel they are supposed to run? I have one I got from a buddy and have to clue about them motors

[@anthonyrizzo255]

87 Or better octane should be fine i personally run sunoco optima 95 because it’s ethanol free fuel it’s way better for small engines than pump gas.

[@matteblackexterior]

just use regular fuel, only go higher octane when you start bumping compression up

[@fn6553]

Why dos it seem that my old 3.5hp briggs has more hp then my 6.75 hp briggs for cutting grass?

[@gmcinnis6304]

its torque that they are using. flatheads have torque lower in the rev range 2200 to 2800.... OHV engines have torque higher in the rev range.... get more HP from the same CC's on OHV engines.

[@marcchaffee7751]

the old flat head motors always have more power than the new gov Newsom smog motors .

[@matteblackexterior]

@@marcchaffee7751idk newer motors are pretty good and when you get them perfect a 212 predator can run 20+ hp and it’ll freely rev up to 10k with no issues, stock id say 6000 is pushing it a tiny bit

[@marcchaffee7751]

@@matteblackexterior My favorite B and S has always been the 190000 series 8HP flateads . Years of gokart riding , that has been the most dependable torque monster for me . Riding all day and they always got me home .
