s-trim blower whine?

at a car show this weekend a 93 cobra drive by and it had a vortech sticker on it. ne never stopped to park the car so didn't get to ask what he had done with the car. his blower was loud and sounded good. now my 94 z28 has a s-trim on it and bunch of other engine mods and mine just makes a whistle sound just like it did with my 52mm TB and homemaide cold air kit with 4inch pipe. what gives? did he maybe have a bigger blower then me? my car is way louder then his since i have straight exhaust, but blower is quite...

Jeff - got my SC installed and car running on Sat night - I can't even hear the SQ trim.

My buddies with 'stangs and SC - they're all louder than my car by far. Not sure what the difference is.

Yo -Aaron. min just makes a loud whistle sound. when you rev it up it gets louder. but driving down the street i couldn;t tell if i heard the blower or the BOV making noise with the air. this mustang sounded good... very notcie just at a 10mph drift going by.

Is your car fixed now?

not even close. have yet to get a hold of a truck to tow my car...... starting to not even give a crap anymore,since i have gone all summer without getting to drive it....

Get that towed up to Big Shot so that I can scan the thing.

dude hook me up with a truck then. haha

Older Vortechs used straight cut gears which are loud as hell. The SQs are barely audible.

i want the old gears.... haha. guess vortech thought it sounded better?? the mustang sounded good.

The helical cut gears (what I would assume you have) are better. The sound is nice though for a cruiser...sounds a little like a gear drive. :cool:

i have the V1 SQ , but it used so have no clue how old it is. but you sound like you know exactly what i was talking bout. i mean mine whistles but if you have no clue what i have under my hood or what the whistle is then you would never think i have a blower until the BOV makes noise. do procharger or paxton make noise?

I like my older generation S-Trim's whine.

My understanding is that if the older S-Trims are sent in to Vortech to be rebuilt, they are rebuilt with SQ parts.

So guess what? Mine's not getting rebuilt unless absolutely necessary. :D

:eek: you suck- haaha..

yeah my V-1 S-trim is really loud. It has a definite whine at all rpms, old ladies look at my car like it is falling apart :D

pm me your email address if you want to see a vid of my car idling through Sonic if you want to compare the noises :cool:

There are a LOT of variables with regard to the blower whine.

- What cam are you running? Stock or aftermarket? Lots of lift, duration, LSA? Cam does indeed change the sound.

- What pulley you running? Pulley size does change the sound.

- Is there a powerpipe that you run for your vortech? If so, that changes the sound as well.

- Someone already mentioned the V-1 "S" vs. SQ = super quiet? LOL.

- Exhaust is a big factor. Does your car have "true" duals or is it still single exhaust? Remember the Mustang is a true dual exhaust setup so that does play a factor in "sound".

I'm told that you can hear my blower (V-1 "S") trim from about a block away. Doesn't matter to me too much these days and I'm used to the sound and the car isn't too much of a sleeper these days anyway (sumped tank, welds, etc).

Enjoy being blown!!!!

i have the V1 SQ , but it used so have no clue how old it is. but you sound like you know exactly what i was talking bout. i mean mine whistles but if you have no clue what i have under my hood or what the whistle is then you would never think i have a blower until the BOV makes noise. do procharger or paxton make noise?

You run a BOV or do you mean "bypass valve?" I assume you're running the "blow through" design and venting to the atmosphere?

i have stock cam-1.6rockers with ex612 springs-mid headers-offroad pipe,loudmouth. my car is loud as crap.... his motor was quite no cam sounds. the older style just has diff gears

BOV- for sound is the main reason why.

I had a Procharger on mine and it made some noise. I actually passed it off as leaky throttle body to a couple unsuspecting chumps. It was nothing compared to a few Mustangs I ran w/ early Vortechs though. It really sounded weak next to an old X-trim. :death:

V-2s are helical cut gears. V-1 and i think all others are straight cut spur gears.
