Well, like i said, has anyone put dual exhause on the passenger side, right in front of the tire? I know nascar did or does do that and it looks pretty cool. I know roush does the one on either side thing, and i was thinking of just being different and kicking it out the side there. Haven't figured out how exactly i would want to do that yet, so i was wondering if anyone has. Pics would be GREAT
thats how i was going to run the exhaust with the turbo, but with out a turbo it would be a pain in the ass and you would lose power doing it for sure
It would be about 2 feet shorter, overall, and i would try to rig up a muffler system, somehow. I don't know why it would lose power though... You need the exhaust system to create a vacuum to suck the air out of the cyl. you do NOT need back pressure, as so many people say. So yes, i will prolly lose a bit of power dut to the lack of vacuum created by the longer pipes. SO... turbo actually would be a good use of it, but NA i'm thinking prolly won't be too bad either. Just wondering if anyone has ACTUALLY done it!
turbomustangs.com there are guys there that have done it...but you need to make a pipe that would cross under the drive shaft in a NA set up and in my car that pipe would be destroyed at the frist speed pump, and you dont need the exhaust to creat a vacume you need back pressuer on a NA set up becuse of the valve over lap in the cam, but in a blown application especialy turbo you need as little back pressuer as possible
Really... Hold on... "Again, you may hear a few SPMT's tell you that "Borla mufflers make horsepower!" Or "An engine needs some backpressure to run properly!" Nonsense. A muffler can no more "make" horsepower than Wile E. Coyote can catch roadrunners. Any technician with any dyno experience will tell you that the best mufflers are no mufflers at all! " http://www.geocities.com/MotorCity/7177/exhausttheory.html http://www.nsxprime.com/FAQ/Miscellaneous/exhausttheory.htm and overboost.com all support that exact quote. "N/A car utilize exhaust velocity (NOT BACKPRESSURE)" http://www.tantrumwerks.com/html/Split DP support theory.pdf "N/A cars: As most of you know, the design of turbo exhaust systems runs counter to exhaust design for n/a vehicles. N/A cars utilize exhaust velocity (not backpressure)" http://www.vishnu-performance.com/exhaust101.htm HOWEVER... YOU CAN'T THROW ON A 6" DUMP PIPE!!! You need a small enough tube to create this velocity!!! Sorry to make it so long, but I've done a bit of research on it, LOL Lee
that third link down mentions that in order to produce velocity, some backpressure must be present. I believe the side exhaust systems (that you can buy) lose power because of the muffler design more than anything. I have no idea why you would want to make the exhaust exit one side of the car like a "stock" car. Those guys only turn left.
I just think it would look cool to have it out the side instead of everyone's basic out the back thing. And yes, like i said, you can't put on a 6" pipe, the motor can only blow so hard to create the velocity. Think of it this way... blowing through a straw, you can feel it, but you can't blow all your breath through it. Get a bit bigger pipe, you can blow through it easier. BUT, blow out to open air, and there's nothing sucking the air out of the cylendar when you have valve overlap, and then you just keep burning the same fuel. VELOCITY, woo hoo!!! We could also get into where you want the power to occur and how the pipe diameter can determine that for ya too, but i think not now... Basically, i was thinking a roush idea, but out one side. Maybe if there is too many probs. going to one side, i'll do like them anyways and put one on either side. Still looks cool, don't it? maybe the roush side skirts and a saleen front?
Oh, so in other words, you have to find the right size pipe for your motor.... Same concept as getting heads that are too big for your car! (oooohhhhh... NOW we understand!) Don't you DARE ask me what size is best now!!!
if you want Numbers to go by, as i know a LOT of guys do, the 2.5 dual exhaust is really fine for up to about 350 horse. Swapping out different mufflers would be even better. Back pressure from a long straight pipe is different than a muffler, depending on the design. The main thing is having the longer pipes, not the mufflers. Although, i WILL be haveing mufflers, IF i do this!!! Which brings me back to my question originally... Anyone got some pictures of this? Anyone done this? Thanks! Lee
Wow, you've read entirely too much. Contrary to your beliefs, you do need backpressure. Sure, run open headers, and you'll soon find out how much torque that you do not have down low. If running no mufflers was the right thing to do, don't you think more people would be doing it by now. This quote right here: "N/A car utilize exhaust velocity (NOT BACKPRESSURE)" is stupidest thing you could possibly say. Velocity is created by a certain amount of backpressure. It's kind of the same thing as cylinder heads. Why not throw on a set of Victor Gliddens on the stock shortblock? It's overkill. Mufflers aren't needed anymore once you are producing amazing horsepower levels (1000+), but until then your going to be loosing out big time. Not to mention that your car will sound like the biggest hillbilly car in town. Call up Ed Curtis, or Jimmy Larocca up and tell them that your running no mufflers because that's a waste of power. If I were a betting kind of guy, I'd bet that one of them would hang up on you. Joe
agreed with the man above, certain engines need back pressure to run properly, i dont care what anyone says, i know from experieice, i switched my H-pipe and one of my header to H-pipe bolts broke so i drove my car for about 2 minns without any h-pipe, just open headers, up my street and down, and my car felt like it lost all power, i have a stock 5.0 engine, these engines stock need backpressure or your just going to lose all power you have. maybe some built up drag racing engines dont need mufflers, but those guys also rebuild their engines every so often unlike most people on here, so i dont believe the no mufflers doesnt hurt thing, on a well build up engine maybe not but not a stock motor
yup, i DID say you need back pressure, BUT the question is HOW MUCH? I DID say that the stock exhaust is good easily to 350 before it starts making a big difference. Back to the straw example, you just can't be too small... Like you said, same concept as the heads, you CAN'T go too big, OR small. Why do you think that those AFR 165's run so well vss the 185's? Same idea! Man, i feel we are repeating ourselves. Basically, i was saying i should be fine putting the exhaust out the sides, not losing too much power, if at all, especially since i'll be putting a muffler on it. Will you agree to that at least?
A GREAT site for the Torque thing is http://www.uucmotorwerks.com/html_product/sue462/backpressuretorquemyth.htm which basically states that "Some say that "an engine needs backpressure to work correctly." Is this true? No. It would be more correct to say, "a perfectly stock engine that cannot adjust its fuel delivery needs backpressure to work correctly." This idea is a myth. As with all myths, however, there is a hint of fact with this one. Particularly, some people equate backpressure with torque, and others fear that too little backpressure will lead to valve burning." And then goes on to explain it all quite simply. Upgrading, NOT eliminating the exhaust
yeah, like a flowmaster american thunder exhaust and BBK off road H pipe would be perfect!!! You got it down man. Might wanna do a bit up top to put more exhaust in those pipes and create a good vacuum with the back pressure! Ok, i'm done now, really i am
Taken from 94Blue302GT's first linked page: "According to the flowbench, two of the best flowing units you can buy are the Walker Dyno Max and the Cyclone Sonic. They even slightly out flow the straight through designs from HKS and GReddy BL series. Amongst the worst, are the Thrush Turbo and Flow Master mufflers. " DOH!!!!
No, technically, thats not true. A side exhaust kit has no proof that it produces more power than a full exhaust system which exits out the rear. We already know that you can't go too big or too small. Why are you talking about velocity, and bringing in all these BS articles that have a very around about way to explaining themselves. This is my article: "Run a full exhaust, dumped exhaust, or side exit exhaust with a pipe diameter of 2.5 or 3 inches depending on horsepower levels. Backpressure and velocity are closely related. Whatever you do, always use a muffler because you will sound like a huge hillbilly if you don't." Thats it. It's too easy. Joe
DEFINATLY agree bout the hill billy thing. Which is why i'm looking into a flowmaster dual in/dual out muffler. other than that, i don't know what i could use other than the actual kits for side exhaust. i still think it would be really cool though. And i'd rather not put on some cheap glasspacks just due to the space constraints. That's still hill billyish. (sorry rich B., i'm gonna miss that truck when ya sell it, especially cuz i can't keep up with the torino)
hey, i put the glass packs on b/c the mufflers just sounded freakin WIERD on that straight six. the torino has mufflers. and the new pickup is sooooo quiet. is it running? wow i can use my phone now!
Bla bla bla blackpressure. Ultimate FLOW makes top end breathing easier (I.E Open Headers, Big Tubing, etc.). The diameter of the pipe sized...JUST RIGHT...will make velocity or speed up the gasses creating a scavanging effect (similar to vaccum) which in turn will produce a nice lowend on an engine. Regardless...this argument will go on forever I'm sure. My previous statment is for N/A cars only. Now back to the ORIGINAL POST. Yes you can do this. Just cross one of the exhaust pipes where the stock "H" cross over tube is. That area has the most clearance near it. Hell, if a MAC Pro Chamber can fit there, I'm sure you can swing a pipe across it. You'd probably run into problems with subframe connectors and getting hangars welded up. Check out DR. GAS' website for different style of tips and tubing. They sell the same exhaust components used in circle track. I just bought a take off set up from a HOOTERS Cup Car for 48 bucks on ebay. WHy i don't know...we'll see though. good luck
