i want a good deep sound on my 92 rs v6. i need a new muffler as well so might as well get a kit right?
i need to know what to get?
flowmaster, magnaflow..ect.?
give me a website, store, parts number, a clue.hahaha.

 

Hooker Aerochamber..

I've had them on my V6's for years and they always sound great. I'll be putting the supercomp kit on my camaro in a month or so.

 

it depends if you want it to be loud all the time. I have a dyno max superturbo exhaust on my 89 2.8. It's loud as hell during wide open throttle and at idle sounds like a 350. and just cruising you don't really hear it on the inside but you can feel it.

Not to quiet, Not to loud....

 

get a 350

 

don't need one...I'm pushing a 305 out of my 2.8

 

a 305 2.8? -_-

 

2.8 with the horsepower of a 305

 

ok? why not have the power of a 350? for probably half the price...

 

proof?

 

My 3.1 has the hp of a '84 LG4!

 

a base 305 puts out 170hp, base 2.8 135hp. correct?! rebuilt 2.8 engine. shaved heads do to engine being blown....All Mahle performance for engine interior (greater compression and combustion), Custom True CAI, pacesetter mid tube headers (kill back pressure), highflow cat from magnaflow (no, exhaust flow restraint) and dynomax catback (no back pressure build up)-all and all increased cfm. stage 2 jet chip that works, 4th gear delay lockup module from jet. (no torque lag)and 180 deg thermo (cooler engine), msd cap and rotor!
there's more to come just need money. still to dyno test and tune.

exhaust 10-15hp
headers 22-28hp
stage 2 chip 15-17hp
intake 10-15hp

192-210hp -10%(for crank)= 172.8 - 189rwhp

and all of this is not including the trans module (no hp rating yet) , or tuning of the car!


and to back it up I go toe to toe with my friends 93 sc400 lexus...which is 205hp (crank)
184.5 at the wheels.

 

3.1 v6 pushing 150hp...nice!
so what did you change or add for the 10hp boost from 140 to 150?

 

^Advanced timing, bumped fuel pressure, ASP pulleys, no cat, home made cold air (no, not pvc). Assuming 18% loss thru auto, its 153 hp at the crank.

Without a dyno, it's really hard to guesstimate the hp. Exhaust on our cars does a lot, but headers & cat-back certainly won't do 32 - 43 hp.....
Best exhaust combo on Earth might be worth 10.

 

I corrected your numbers to show realistic gains from those mods.

 

you don't lose hp from auto trans. only when you have a manual trans. and 18% is overkill for any hp loss on any car. unless you clog up the pipe

and just to tell you bro...scientific fact- just by changing a stock muffler to a freeflow performance muffler can unleash anywhere between 10 to 15hp on majority of completley stock cars.
I'm not trying to be a know it all or nothing. I'm just throwing in my

 

so you should be pushing about 162.5 rwhp

 

explain me staying toe to toe with a 93 sc400...

 

Bad driver, tired engine in the SC, or a thousand other factors.

 

I have Magna-Flows on my 91 firebird and it sounds pretty good
BUT!
The flowmasters on my 98 Camaro are nasty!
And the difference is the 3.8 Series II Supercharged V6 engine.

I havent tried flowmasters on the 3.1 V6 yet...
cause im kinda impressed with the magnaflows!

 

you are so full of **** bro. what the hell makes you think that i'll only get 2 hp out of some headers.....

 

Maybe, but the dyno read 122.8 at the wheels....

 

you need a tune up and when you do go with the expensive lubes for oil, trans, and dif.

10hp gain easy off of lubes.

and for the mod...look it up bitch!

 

Whats your compression? Details on the engine internals? Camshaft?

Do you have any stickers? They are an easy 10hp gain! EACH!!

 

Wow, you guys really need to get your numbers straight. First off, there is a HUGE loss of power between the engine and the wheels. Somewhere between 35% and 45%, depending on the trans. Manuals tend to lose around 35% and autos around 40-45% due to the fluid coupling in the torque converter as well as the large number of clutches and crap that makes it automatically shift. Then you have the play in the rest of the driveline that loses power, and the constant dragging of the disc brakes, the tires, and anything else that could slow the car down (weight).

Second, we're talking about a small-displacement V6 here. So, you're not going to get anywhere near the numbers out of the 2.8 as you would, say, a 350. And even those numbers are exaggerated a LOT by parts manufacturers to make them SOUND like they're worth the money. I'm sorry, but you're NOT going to get 10-15 HP out of a fluid change, whether you use el-cheapo parts store brand fluids or expensive Mobil 1 or Royal Purple, B&M Trick Shift/Stick Shift, or any other insanely expensive fluids. You may get BACK a couple of lost HP because of the who-knows-how-old fluids, but you probably won't gain anything. If anything, the car will SEEM like it has more power due to the fact that less is lost due to friction.

Again, small displacement V6+tiny intake ports and restrictive intake+3000 plus lb car+restrictive exhaust+old parts+barely tuned ECM to match current setup = not very much power gained.

If you wanted power, you could have spent all of the money you wasted on the restrictive iron heads and even more restrictive intake and gotten a late model top end and 3.1 pistons to get you 30 HP out of the box and put on a matching exhaust. And swapped to a T5 with a Fidanza flywheel or compatible. BTW, if you got an exhaust bigger than 2.5", you wasted money there as well. You're losing power with anything bigger than that.

:edit: Oh, and BTW, those Pacesetter headers aren't exactly a match for our engines... I read in a GM Performance guide a while back that the ideal exhaust port length (in the head plus in the runner for the manifold or header) should be 33", with all ports the same length. The Pacesetter runners are neither 33" long nor the same length. Yes, they do free some power, but you could probably have better ones made.

And how exactly did you increase the intake flow WITHOUT changing either the throttle body, intake, or the head ports?

And, guys, we should probably get back on topic here...

 

Get a V8........

 

mine has headers and a full exahust and every basic updgrade you can do minus a cam and i only put out 133 hp and 178 tq at the wheels, the upgrades really dont add much

dont get me wrong i noticed an increse on the butt dyno when i put the exhaust on but i promise your not putting out what you think you are, and that was on a 3.1 motor im about to dyno the 3.4 motor i built and that motor will probably run the numbers your talking at least

as far as a good sounding muffler at hight rpms on a v6 ive yet to find one

 

No..... That would mean on a conservative estimate my mostly stock 3.1 has over 200 crank hp.

200 - 40% = 120.

Like you said to the other guy, no way in hell I can pick up 60 hp from basic mods.

15% or less for manuals, 17 - 20% for autos, 17 - 25% for AWD.

 

mine is a manual guess thats where i beat you in the hp huh lol

 

lol.. this topic sure turned funny fast...



OP, that's not how things work in the real world. Your engine is probably making around 140-145 @ the crank if you are lucky.

 

hey how did that hooker areochamber sound in the higher rpms?

 

Not sure ATM where I picked that number up, but I'm pretty sure it was a very reliable source, being either someone reliable on here or in one of my many textbooks. And I DO know it was WAY more than 15-25% power loss. I know I was surprised at the numbers myself.

Oh, and Iceman, I would seriously consider getting a camshaft ground, new fuel injectors, an adjustable FPR and V8 fuel pump (preferably a Corvette pump), and some serious head porting if you want to see the kind of numbers you're predicting for your engine. The set up you have now is WAY weak on the intake side. And you might want to do a little more with the transmission as well, either swapping to a 5-speed or having the existing 700R4 rebuilt with a shift kit, Corvette servos, and a better torque converter. Then you might want to deal with the brakes and suspension, and the trans mount.

Also, that lockup delay solenoid thing is useless if you want to get your ECM reprogrammed... You can reprogram the ECM to lock the clutch whenever certain conditions are met, engine temp, certain gear, certain throttle position, certain speed. Just like you can disable the EGR and other emissions equipment. You ARE going to disable the EGR, right?

 

i live in cali bro! sorry

 

if wat you say is true...then i would still be pushing a 305 if there 170 crank then there 150 at the wheels! either way v6 with power of a v8.

 

really good however i was running tuned longtube headers with true duals and an X pipe.


Here is a friends 300HP 3500 swapped Sunbird with the Fbody Crossflow muffler installed. Yes it is a little farty on decel, i need to work on his tune a bit more.

And that's honest power too

 

Ice_man, your gain numbers you posted were way higher than they should have been. You forget though, some mods, especially exhaust, may not give big HP numbers, but they can greatly help acceleration and throttle response. The other thing your forgetting is while the 395 and 3.1 has similar HP numbers, the difference in torque was bigger.

To this thread maker, there is a HUGE thread about mufflers. Lots of good info and sound clips can be found here:
https://www.thirdgen.org/forums/v6/5...fflers-v6.html

 

Sigh, fine, believe whatever you want. It really isn't worth arguing with someone who already knows it all.

 

i hear ya bro....no disrespect.....so all the hp ratings are crank, and one other thing, i thought the law changed before 74 about hp ratings having to be at the wheels and not the crank, so if you had to say so wat do you think i can make or making for me to keep up with my friends sc400

 

yes all the hp ratings are the crank not the tires

a stock 2.8 will typically dyno 95-105 rwhp and slightly more for a 3.1 and 3.4 respectively

when my car was dynoed i was told by the dyno operator that an auto with a highstall like mine and a steep rear gear ration (4:10's) will have about 25% drivetrain loss, so one with a stock converter and gear will prolly be around 18% for auto and 10 ish % for a 5 speed manual

 

ok so with all of this said and now fully understood, how much do you think I'm pushing to stay toe to toe with my friends 93 sc400? I respect your opinion and that's why I ask.
Just be straight honest with me ok bro?
and just incase you want to know his sc400 is stock....the only thing he did so far is change the plugs and for what ever reason he did it, took the mufflers off. I'll admit it sounds meaner but still don't know why he did it.....
I mean we live in California come on

 

-50 HP & -45 TQ for the driver hahaha

put a turbo or some juice on it and call it a day.

 

I have one more question I know! but I have to ask....my friend joe has a 67 mustang with a 302ci and it's only a 2barrel.....he says he doesn't think it's pushing over 200hp. I don't believe him at all do to the fact that I can't hear myself scream when his car is on and standing next to it. he want's to race me! I mean I know I can keep up with the sc400 but old school muscle like that scares the **** out of me.....
I need to know if I should give him his race.....If I do race him he said he doesn't have a problem with me recording but I personally believe the odds are way against me...

 

I have an 80 series Flowmaster on my 2.8 and it sounds mean as hell.

 

WHY? Loud does not equal performance, I just do not get it...

 

You have to understand that horsepower isn't everything, You need torque to move these heavy cars around. Sure a 135 HP 2.8 is fairly close to a 160 HP 305.. but at 160 ft-lbs of TQ VS 255 ft-lbs the 305 will always have a power advantage.



the 302 must have been swapped into that '67. They came stock with a 289 or a 390. If the engine is still stock it probably runs mid 15's. he will win against your 2.8.

 

lol Its not that loud, just has a meaner exhaust note and THATS what I wanted. For the performance side, I have been tuning the ECM, and i have made some of the swaps that bl85 has posted about with some real nice gains. No it wont beat a corvette, but its more fun to drive now. The reason for the muffler is twofold, one it sounds great, two, it will last alot longer than the cheapo parts store ones. I believe the OP wanted to know what would sound good on his car, not "lets see who gets flamed for giving suggestions"

 

My v6 133hp 178tq... My stock 5speed 91 305 firebird ran 134 ho and 216 tq... It wins but just barley

 

Your 2.8 must be putting out at least 290hp and even more torque to beat an SC400, those cars make 250hp/ 260 lb·ft. You wont like this but, unless his SC is a manual and he is totally incompetent, there's no way you you ever pull ahead. This idea you have that you're faster than your friends SC400 is bogus. Your car weighs more and has about 100 less hp and 70 fewer lb ft.
"Old school muscle" is overrated. The SC would wipe the floor with that mustang too.

 

lee's sc400 is a 93 and automatic w/OD
still doesn't answer my question about the mustang

 

it's not his exhaust that's loud it's the damn engine itself.

 

yeah I know about the engine. the only 67's with 302 were boss. well I hear ya bro...I think I'm going to give joe his race just for kicks and my other friend levonne record it....when it's all said and done I'll post if up on youtube and then on here
