zlumload, Tell us more about first Camaro. We never see it in any other videos. What's his name, where is he from? Thank,s Steve, west coast pro streeters.
Really nice cars, but the blower surge......Yikes! These folks could use some tuning assistance. I know folks at the car shows thinks that sound is cool, but the reality is the engine is not tuned properly. The Corvette at the end of this video sounds right.
michael Griffin - you have absolutely no ideal what you are talking about, This is an injected set up....some blower set ups have carbs. What you are hearing is blower surge. The engines not shutting on and off. The engines going lean to rich whens its idling. Carb and injected both surge
Wow what a video, if you shake your head as much as the camera maybe then you can watch it hold the camera steady,ifvyou going to be out here doing this do it well vfc or go home!
It's not blower surge that you're hearing, it's the cam. Camshafts are are designed for different rpm's. It's either going to idle smooth or have top end power, or a compromise in between. My guess is that most of these cars are made for the track and barely street legal. That's what prostreet is all about..
No....look up and compare a hot street blower cam specs and compare it to the specs for a hot street naturally aspirated (NA) cam with the same lift - blower (and even Turbo) cams have less duration and valve overlap - less of both of exactly what makes a NA cam 'lumpy'. Also look up roots type superchargers like these to understand how they work. They are not constant volume / pressure pumps. The pressure is delivered in spikes. That is why the engine surges at low engine speeds. It's because the manifold pressure is bouncing all over the place high / low. An old 2 stroke GMC Detroit Diesel surges like that, too, when anything about the governor settings or tune-up is off even the slightest. Even though those diesels have huge and heavy flywheels, crankshafts, rods, and pistons -all that tend to smooth out the idle through shear mass / inertia. Guess why. It isn't the camshaft - the old 'sceamin' Detroit 2-stroke has barely any 'cam' duration or lift in it. The camshaft is actually pretty 'mild' compared to most any automobile gasoline engine's cam. And it's a 2-stroke, so the cam only controls / activates the exhaust valves (and the injectors). But they all use the same design roots blower (on the Detroit, it is called a 'scavenging blower'), and that is why they tend to surge. At low speeds, the manifold pressure jumps up and down wildly because the blower is pulsing the manifold pressure up and down. It is even worse when the blower is driven at anything other than a non-hunting timing gear set, as is typical in the belt drives these cars use. It is near impossible to maintain a constant engine speed when the manifold pressure is constantly and wildly fluctuating how much air and fuel are being pushed into the engine.
can somebody tell me if that first car in the video was idling right but it have to be tuned up a little bit because it seemed odd how old would idle high then go low what causes that is that just how the blower works I hope I don't sound like an idiot for asking that question I'm not what you call a gearhead but a fan of old muscle cars
well i can cvouch for black vette with huge hat it runs cecil county dragway,1st camaro is a runner at capitoil,white does runs outlaw big tire. thta jeep runs 8's check my youtube video,red,white,blue nosta,gic car runs track,purple gto also runs, gold buick aka buuwack runs 8.60's,
It`s all so beautifulllll.....song comes to mind
Excellent video...
+Brazen Thayer alot of those cars run low 8s & hi 7s. Take a look at the passenger sides of the cars & you'll see NHRA certs on the main hoops.
Wow! Did i see a hemi under the hood of a Chevy ll ?. That's a step in a different direction!.
yes you did
That yellow Chevy reminded me of the car from the Hollywood Knights. LOL!
To me American and Italian cars rule and masterpieces

buddy busser from md its a drag car runs with mid atlantic street outlaws and warriors

mikenstacey Blower surge is cool.
+mikenstacey we know it isn't, but it has zero to do with performance, just a idle.. surge is the shit. it clears up once you stab that pedal.
image is everything, Its done on purpose, & besides it looks & sounds great;;I love it
Have lc torana 2door 383chevy motor roller cam dart heads twin carbs tunnel ram 520 horsepower from Scott new Zealand
zlumlord, I have a friend that admires Mr. Buddy Busser surging Camaro so much he wants to buy it. How can we get in touch with him. Sharkman
i sent him a message ill let you know
Dude with the PSI blower on the nova is doing work,, that pulley was small. I guarantee he runs that car

You obviously don't know shit about blowers and for that matter high performance cars in general.
Listen too that camaro it's says floor me
Blower surge is the shit, I don't care if ' the idle circuit " isn't tuned right.. It is the shit...
+mangler0075 yep!!!!!!!
Amen
mangler0075 couldn't say it better
Injection is nice, but I'd rather be blown!

you are absolutely right Jeff4576, & I love it
When does this happen? Have got to go!!!

+John Tuttobene PS I think my favorite car that looks and sounds the best was that Chevy at 8:04 into the video just my personal opinion though
+John Tuttobene bower surge
The mighty Buu wack
They should have the event at a drag strip, so we can watch them run all out, instead of listening to the Blower Surge Nationals.
Half of them are bliping the gas pedal to make the surge worse. Plus if they lean out the fuel system a little most of the surge goes away.
@@jeeplvr2000 you wanna bet how much money ya got
I can't help to think these are just all show cars and never actually run on the street or track. Like the cars only come out to shows and that's it
well i can cvouch for black vette with huge hat it runs cecil county dragway,1st camaro is a runner at capitoil,white does runs outlaw big tire. thta jeep runs 8's check my youtube video,red,white,blue nosta,gic car runs track,purple gto also runs, gold buick aka buuwack runs 8.60's,
That first one was annoying.
tune it for him then
Put your money where your mouth is! Race me!
Blower surge sucks.
