Those high performance cars backfire during rev deceleration because they're designed to do so. Some of them seem to be doing it just for fun, but the more serious high performance cars do it because fuel is being dumped in order to cool the valves and and that fuel then ignites in the exhaust. Have you never heard of this? If you still think it doesn't make sense, what better method do you propose for keeping valves cool (these cars also often have titanium intake and sodium filled exhaust valves)?

The "don't need back pressure" thing is especially true for turbocharged cars. You want as little restriction as possible after the turbine, otherwise the pressure will actually hurt the spooling characteristics of the turbocharger. It's why on big turbo cars, you see the catalytic converter either: replaced with a high flow racing cat, removed, or moved farther down stream to reduce restriction and improve turbo spooling. Even a small size upgrade, changing to a lower restriction exhaust has improved responsiveness due to letting that turbo spool more rapidly.

Agreed, just bought an X5 M twin turbo V-8 all tricked out for the track. It has after market straight pipes that are 1.5" larger than the stock 'M racing package' that came on it.

@LynchMob09R Рік тому
wouldn't a blow off valve help as an alternative to the muffler change?
@ajkooper Рік тому
@@LynchMob09R no, since the blow off's function is just to prevent pressure buildup in the intake to either keep the turbine spinning after you let go of the gas pedal and close the throttle valve, or limit the maximum pressure to keep your engine in 1 piece. Back pressure in the muffler will have an effect on how much the turbine can spin or keep spinning since the exhaust pressure and flow is the active force that makes the turbine spin.

At my high school in the 80s the thing was either slammed "Cal Bugs" or "Baja Bugs", but the VW Bug was THE car to have and modify - and of course there was a rivalry between either the lowered Cal Bugs and the Bajas... one day after school a Cal Bug passed my brother and I (we were in the Baja Bug) and the driver of the Cal Bug kicked on his NOS to pass us up a hill... he left the valve open too long and all we saw was the rear hood and engine parts explode out the rear of the car. The damage was so instantaneous and massive that it stopped his car almost exactly where it blew (it locked up the rear drive wheels and shredded his tranny, too) ... yes, we beat him to the top of the hill laughing all the way and never looked back!

Minor correction: the SAAB Sonett had either a three-cylinder two-stroke engine, or a V4, four-stroke engine sourced from Ford. A long time ago I really wanted a two-stroke Sonett but I never saw one. I did have a '67 SAAB 96 Monte Carlo, and that model's high-performance two-stroke engine (60 HP!) had three carburetors (the highest carburetor-to-cylinder ratio of any car I ever owned). I don't know if the two-stroke Sonett came with the triple-carb engine, but as it was a sports car my guess is that it did.

He had been interested in the Sonett II which were all 3 cylinder 2 strokes. But he was too tall to sit in it. His two previous cars, a Lloyd (British) and a DKW (German, one of the 4 companies that merged to eventually form Audi, hence 4 interlocking ring logo) were both 2 stroke, fwd. The 68 SAAB 96 was available with either the 3 cylinder 2 stroke or the V4 4 stroke. He opted for the larger displacement V4. Btw the Sonett pic Scottie showed was of a Sonett III, which were all V4 4 strokes

Thank you for that explanation about back pressure. I can’t stand it when I get on forums trying to research a certain mod for my 392 challenger and I constantly see guys scared to do certain mods because “it’ll reduce the back pressure.” The only engine to my knowledge that needs back pressure is a diesel motor.
@passattdise 2 роки тому
The only time back pressure is a hindrance is if you run your engine at full throttle, all the time. That's hardly the case in a car on the street used for transportation. You're lucky if you use 10 to 15 HP going down the freeway on a clean aerodynamic car on level ground. That's nothing when the engine can make 300 -600 hp. Even Turbochargers make a lot of back pressure, by a factor of 3:1 on the turbine side vs the compressor side. So if you're making 25# of boost on the compressor side of a turbo diesel, there's about 75# of back pressure on the turbine exhaust side. Can't get one without the other. Don't say it's bad, lots of vehicles run turbochargers and run full throttle applications, and the back pressure on the exhaust does no harm.

There is a devise that is used to keep a turbo spooled up by causing the engine to backfire. That backfire which you may have seen is due to an anti lag system or a misfiring system in tuner terms. The anti Lag system keeps the turbo spooled up even when you are not on throttle so that after you exit a corner and step back on the accelerator you have that boost ready for you and hence eliminating turbo lag.

The celica had a stainless steel exhaust system. You keep your car pretty clean mine was showing some rust I loved it to my sisters kid he drove it in the snow ice and crap and never washed it, road salts quickly took there toll. But the muffler was still good.
@darthhodges Рік тому
A lot of "high performance" mufflers are designed to have higher flow rates to reduce the negative effects a muffler has on your car. The downside is that they won't be as quiet as a typical muffler and most are dramatically more expensive than typical mufflers. But sometimes halfway is the best you can legally get.
@bradgriffith4231 11 днів тому
Magna Flow muffs are excellent. Straight thruogh perforated tube with a non-deteriorating sound absorbtion material. No drone & minimally increase exhaust volume. I've run them for 30 years. ALL mufflers with baffles, even "high performance" versions are detrimental to performance. It's called "fluid dynamics" & a common example are rocks in a stream. Every rock disrupts smooth flow & the same thing happens in an exhaust. The newer cats are very minimally restrictive.

My first car with the muffler behind the rear tires like that never lasted long. One rusted away but it was welded on so the inside part was still there. Think I out the muffler on backwards so it would fit over the old insides still there. Worked great and the quietest that car has ever been. Once that muffler was going bad though I took it someplace to get changed. They told me that they had to cut it off as there was an adapter welded on. Adapter? Ha it was just part of the previous muffler.

Most of the big trucks the younger guys drive where I live in Georgia sound like piston driven airplanes, and most of them are tuned to perform just fine without backfiring. They are extremely loud, but they seem to run just fine. My truck has a less restrictive custom cat-back that performs & sounds very good without being loud. All 4 factory cats are in place, and I do have an adaptive tune so it doesn't backfire.

Good info as always Scotty, but I wanna know if there is a way to reprogram the injectors on my 2016 Frontier SV ? It's 310hp mpg is crap, would it be possible to knock it down to say 250 or less & up the mpg ? Thanx.
@passattdise 2 роки тому
No.... your mpg is crap because the car wasn't built with an aerodynamic body and has a high coefficient of drag in the body design. It just doesn't push air out of the way very well at highway speeds.

Hey Scotty, you're usually 100% spot on. BUT......there are engine tuners who can alter the Engine Control Module (ECM) that can tune your car to BETTER gas mileage, go from 1 7/8" to 3 1/2" exhaust (for turbos) and make it run faster & better. I've had a Miata that I added a 2.5 Liter Ford Focus engine, a turbo, and big 3" stainless steel exhaust & muffler. It was a BLAST to drive!

Had the shell of the pre-Cat on my 2005 Nissan Altima crack and the exhaust was finding its way into the cabin. I verified the crack by pumping air up the exhaust pipe (with engine off) and probing around near the pre-cat with my mechanics stethoscope with just the rubber tube. I isolated the air hissing sound escaping at the pre-cat and replaced it with one made by Walker. Two years later, same thing happened and they replaced while still under warranty. Did the work myself and it was not too hard.

@petenielsen6683 2 роки тому
The computer codes said the left bank was running lean in my car and suggested replacing the oxygen sensors, but my trusted mechanic found that a valve in the exhaust manifold was missing and the air rushing through at full force blew the gasket. Such a shame I had not seen your UKposts channel before I bought my 2014 Cruze. Of course Chevy invited me to go to a dealership to have the problem fixed for free AFTER I had spent the $800. And its fix was only for the PCV valve issue itself and probably didn't include the gasket replacement...

Newsflash. My Piper Cherokee airplane has a muffler which was installed by the Piper factory in Vero Beach, FL when it was built in 1973. I can’t think of any light general aviation airplanes powered by Lycoming or Continental engines that don’t have mufflers although I do know of some that have been modified with PowerFlow exhaust systems which are analogous to headers on a car. Interestingly, the design of these engines are virtually unchanged since 1942.

If the fuel injectors get upgraded [+ lets say fuel pump n' such to accommodate]. Wouldn't the air flow need to open up a lot more, [more aggressive intake/throttle body/forced-aspiration/etc], to avoid drowning the cylinders with fuel / choking up CC?
@sandman6851 2 роки тому
All things are relative , to really do it right some people set up their car depending on the final gear ratio of the rear-end.
@pontiacg445 Рік тому
Not if you have control over the injection timing pulses. Say you went from 200cc injectors to 400cc injectors, you'd just need to hold the injectors open for half the time. That's more or less what people adding turbos and standalones to cars are doing. Most fuel injectors don't like accurately cycling much quicker than 2ms pulses, so you can go too big. A gigantic turbo on a small displacement engine might need staged injectors to keep from idling at 10:1 fuel ratios while still being able to keep enough fuel when the turbo really starts pumping.
@genericdude6551 2 роки тому
