I have a brand new, installed, but never cranked ZZ4 350 in my '92 RS. I believe it has around 9.8:1 compression and the mods are in my sig.

I want to run easy 12's with a relatively quite supercharger setup. Anyone have any solid recomendations?

------------------
'92 RS-SS, ZZ4 10:1 350, Edelbrock 6085 heads, GM LT4 1.6 roller rockers, Crane 208/214 467/482 112, Edelbrock TPI, Accel 24#, Holley afpr, SLP 1-5/8" Jet-Hot headers, Catco 3" cat, Flowmaster American Thunder dual 3", Hughes 2500 stall, stock 700R4, Auburn pro-posi w/3.42, SFC, Walbro pump, ZR1 17x9" rims, BFG ZR's, Medium Quasar Blue w/white SS stripes....

 

Anyone??

 

my dad has a wieand 142 roots blower on his ZZ4 and that car F-in scoots. Runs good, just have to pull a bit of timing out to make sure it doesnt eat itself

 

If you want to keep the TPI then a roots style setup is out.
A centrifugal supercharger will bolt right up to your TPI throttle body and the inlet charge will run cooler too, which is a good thing with a compression ratio around 10:1.
If you want extremely quiet, You could try a Paxton balldrive unit but based on my own experiences I wouldn't recommend it based on reliability and heat build up issues. There are better options out there these days.
Vortechs have a better track record as far as reliability goes. their gear drive systems run cooler than Paxtons ball drive systems. The downside to gear drives are the gear noise. Vortech does make some that have quieter gear drive systems though.
Prochargers are also reliable and cool running but also a little (or a lot) noisy.

With compression that high you will want to watch carefully for detonation.
You will need to make sure that the air fuel ratio is rich enough.
You may need to reduce timing advance.
Using water injection may be a good idea.
The vortech liquid to air intercooler (Aftercooler) or Procharger air to air intercooler would reduce the chance of detonation and improve power output.

Thanks Tracy! I think I'm leaning towards the ATI intercooled, and I wanted some opinions from people's experience.

I've heard that Paxton seams to have some issues. I've heard the Vortech first hand and it's very loud! I want a quite setup if it's possible...

 

u could try a powerdyne they are quite but the belt goes bad every 40,000. but it is just like changing a timing belt. plus they run cool. personally i like the procharger eventhough it is loud

Vortech makes loud and quieter versions. The quieter ones have angle cut gears & still have noticable gear whine but it's not real bad compared to the ones with straight gears.

The prochargers are louder. The quietest Prochargers are the self contained units. I don't know if they have a different cut of the gears or because of the internal oil sump dampening the sound or perhaps both.

I ordered my D1sc with the noisey gears and it tested at 97dB's, Willie ordered his D1sc with the quiet gears and his tested at 96dB's...hhmmm not much quieter...

I can say that my blower is very noisey at idle and very low rpm's, but when cruising you hardly can hear it. until you tromp on the gas pedal, then hang on cause the road is going to get very short very quick!

Larry,

What's the difference between the 9psi P-1SC and your 10psi D-1SC? The intercooler? I would get the "quiet" gear which would make it the P-1SC"H". Not much difference in sound you say, huh? Any problems with the install or other stuff?

Also, what did you pay and where did you get yours? I'm just about to order one through Tom Byrne's GP and the price looks real good. Just want to make sure...

Thanks!

 

'92 RS-SS,

The difference is the amount that each unit will flow, the P1sch flows 1200 cfm max, and the D1sc flows 1400 cfm max. also in kit form the 3-core intercooler come standard with the D1sc.

The biggest problem with the install is the instruction manual. too put it bluntly it SUCKS!

I paid just under $3800 with the polished blower from http://www.performancess.com

Cool...Thanks!

Would anyone else suggest that he run the engine for a few thousand miles before putting on a power adder? I have heard that it is a good idea to let things wear a little.....

That's a very good question. Anyone have comments on this? I'd hate to crank up my brand new engine/supercharger combo only to find out that the engine has some tuning or other issues!!

 

I can't really think of any legit reason (except maybe an empty wallet after a crate engine puchase ) for waiting to install a supercharger unless you are not experienced at tuning. If that is the case it would be a good idea to bone up on it before you even begin to do a swap to any engine or make any major mods with tuning needs unknown to you.
The supercharger should not be a tuning issue at all when not under heavy acceleration.
Then when under boost conditions you just need to be sure that the timing advance is not excesive and that the air fuel mixture is not too lean.

As far as "breaking in" the engine goes it will be just fine being broken in with a supercharger, turbo or nitrous system bolted in place.
As long as the engine is built soundly it will be fine. If it's not built correctly it will come apart anyway, power adder or not. The bearings & rings will wear in the same regardless.
If breaking in without the power adder was a neccesity then we would have had to take our twin turbo Supra back to the dealer after __thousand miles break in time without the turbos to then get the two turbos installed to keep our engine/powertrain warranty intact.

 

Well said...supercharger it is then!!

Imagine this: the car barely had 200hp before I yanked the wimpy 305. By the time I drive it again, it will have 500+hp!! Woohoo! Can't wait!!

 

That's awesome..but why do people prefer super quiet superchargers? Maybe it's just me, but I like that low whine...and I love it when cars drive past me and you can hear it...for you know, there lies POWER. :P

Irocz4me,

You are correct, When i get finished rebuilding a Caterpillar Diesel, as soon as the engine gets to operating temperature, the truck is put on a chassis dyno, loaded down, then checked for specified hp and torque.(600hp-1750ft.lbs torque @ approx 27 psi manifold pressure(boost)).
let me tell ya, if somethings not put together correctly, you'll find out right away.

And for BahamutRS,
I love my noisey ATI D1sc, i wish it was louder at times, so i don't have to hear those damn pony cars!!!

Don't get me wrong, the loud whine at full boost is awesome, but at idle, I don't want my car to sound like a street sweeper!!

I guess if your in the 500hp range, what's a little noise anyway? I remember how many heads my buddy's '89 GT would turn. It had a super loud Vortec S trim on a built 306, and man that thing was loud at idle and almost deafening at full throttle! Very nice...

Anyone have pictures of an ATI on a Camaro? Please post 'em!
