Supercharger question

[Redog]

Stopped at the junkyard today and I saw a Buick Park Ave with the complete 3800 s/c motor, they also had 2 GA's with complete 2.4 Twin Cam motors both 5 speed, one had 87K miles, and an Aroura with another complete motor :eek: :eek: :eek:

Anyway, I was going to pull off the s/c and try to fab it up on the Alero, but I was unsure if it would fit or not, the car was a 97 so I'm pretty sure it's a M90 s/c but when I asked how much the s/c was if I were to pull it I was told $1K.

This place is expensive and they are assholes there anyway, but the good junkyard has an Alero they have to wait another 2 to 3 weeks for the title to be thiers.

Anyway, what s/c is better for the 3400? The M62 or the M90?

[[ion] C2]

pull the 5 speed trans for me

and yeah that M90 is WAY, WAYYYYYYYYYYYYYY overpriced. what's better? the bigger the better. lots of fabrication to get it to work on the 3400 though... turbo setup's better

[meadus101]

Redog is the fastest All Motor Alero... Stay NA!

[Redog]

^^ HA HA yeah.

Probably will anyway

[[ion] C2]

no, screw N/A. Not Acceptible. N/A is expensive and slow. Boost is cheaper and quick. The sound, the fuel economy, the power. It's great. You'd probably change your mind if my cat wasn't clogged at ASS lol.

I'm sure that'll "wow" everyone, an N/A Alero running mid 14s.

What you need are 11-12s. 14s are nothing impressive anymore... You've built it up N/A, now add the final touch, the boost to further all that existing power.

[Ryan from Ohio]

That would be an intake nightmare... better have an engineer friend with good CAD skills.

plus you can get just S/C off fleabay for under $200.

[[ion] C2]

Not really, look at how the kit for the 3400 is... all you need is a plenum outlet to bolt the supercharger to and then run charge piping from it to the maf/throttle body. You'd have to make a loooong rod to reach the accessory belt though, just like how the limited run 3400 M62 kit was, and RSM's kit is.

[BlackJack]

wow, I guess I better get off my ass and start making a "no-hood" GMC 671 S/C kit.

hmmm....since the base plate is made to fit specific applications using the same S/C body........I wonder.

[[ion] C2]

would look stupid sticking out of the hood with the engine mounted as it is FWD

[BlackJack]

yeah, I guess you're right.....that would look stupid running 10's in the 1/4 mile. That would look REALLY stupid.

I'm not exactly the guy to worry about how shit looks. If I have to balance looks and (serious) performance, the Alero is not the way to go. My hood is currently canted at the rear about 3" up so I can fit my intake. I'm not happy with the way it looks completely, but I'm happy with the way it eats corvettes, S/C mustangs, and SRT(insert number here) that are contemplating how stupid it looks.

[[ion] C2]

yeah, I guess you're right.....that would look stupid running 10's in the 1/4 mile. That would look REALLY stupid.
visually it would, a supercharger sideways poking out the hood just wouldn't look right, turn your 3400 sideways and RWD swap it!

corvettes!? i'm very impressed :rolleyes2:

[[ion] C2]

i also ate a corvette. it ran 16.4 though.

[billytheman1188]

C2;407763']i also ate a corvette. it ran 16.4 though.

WOW, clearly that guy doesn't know how to drive:eek:


and ken.....i agree with ion, if you put a turbo on redog, or a S/C.....BAD ASS:coolio: i would say turbo......BOV ftw!!:rolleyes2:

[kwhauck]

when speaking of a custom supercharger setups, just stay away from hEatons in general, but yes probably more cost effective to go turbo.....i know i will be running 14s NA, hopefully 13s, before i actually throw the boost to it.....

[NickAlero2000]

you can have an s/c with a BOV, like in the M62 setup for the 2.4L...

Took the words right out of my mouth :p

[[ion] C2]

you can have an s/c with a BOV, like in the M62 setup for the 2.4L...not with the way it's being designed...

the supercharger would have to be before the throttle body

[Bad99Olds]

not to totally whore out the "fastest na alero" comment, but im pretty sure, if i remember the thread, jackal2000 was actually faster, reddog just treed him, please feel free to correct.

[Cliff8928]

C2;407724']pull the 5 speed trans for me


Don't forget the subframe assembly, shifter and cables. The engine harness would make things easier too.

C2;407748']would look stupid sticking out of the hood with the engine mounted as it is FWD

You think so?

This car was in Warren, btw.

I'm hearing you guys say "build it up N/A, then add boost". I was under the impression that when you ran N/A, you had to raise compression, and lower it when building for boost. I believed that you could only go one way and to go in the other direction, you'd have to remove all components used for N/A compression and install lower compression ones. The way you guys make it sound, it's all linear. Are you guys just making it sound simpler than what it really is, or is it really that simply?

[[ion] C2]

you don't have to raise the compression ratio N/A

[kwhauck]

yes you don't have to raise or lower the compression for either setup, and yes my setup is being built for big boost, and some things will not work as well if i was going for NA only but it doesn't mean the motor without boost will be a slouch.....

btw, linear no, HP vs Money is an expotential equation, the higher up on the scale, the more money you need to spend to squeeze out the little extra ponies........

hmmph didnt know your car could beat SRT10 vipers......510 hp..... didnt know that your car was faster than that...

[will176]

haha i think its actualy 600 hp unless your talking about whp. ya if there is an alero running fast enough to beat one of those, please post your setup so i can clone it ;)

[Vinalero]

SRT10 viper bone stock do around 12 sec flat on the 1/4, I'm sure BlackJack is really not far from there, if not faster.

[Oldsman]

C2;408006']you don't have to raise the compression ratio N/A

if your going all out motor you have to raise compression to get the best results out of all out N/A. This is what drag racers and motor builders have done for years and still do today.

Can you have a good running motor on 9:1 compression......YES. will it run a lot better and have the best performance on 12:1......YES.

[Oldsman]

Always had a question about this, and I guess this thread would be the best place to ask. I'm hearing you guys say "build it up N/A, then add boost". I was under the impression that when you ran N/A, you had to raise compression, and lower it when building for boost.

The way you guys make it sound, it's all linear. Are you guys just making it sound simpler than what it really is, or is it really that simply?

you are correct. Going all out N/A race you need to raise compression to get the best performance and get the n/a to breath the best. this usually results in a range of 11:1 - 14:1 compression, typically. So if you have your motor build for all out N/A race and then want to boost then yes you have to drop the compression by replaceing the pistons to get compression somewhere 8:1 - 9.5:1, typically.

[CiscoPath]

Thanx, Oldsman. I knew something had to be swapped out. So the only deciding factor in NA/boost are the pistons? I thought camshafts had something to do with it also.

[kwhauck]

.....everything goes together if you are serious about making power, that is why you blueprint a motor

but that doesn't mean that a well built NA motor won't make power with some sort of forced induction, when you blueprint a motor, it is all about effeciency and squeezing every little HP out of a certain setup wether it be turbo, supercharger, or NA

[BlackJack]

hmmph didnt know your car could beat SRT10 vipers......510 hp..... didnt know that your car was faster than that...

Not...yet...... ( I don't count the SRT10 RAM truck, those things are slugs)
I'll drop a little hint though, it won't be long after I return home that I'll require a 10-point cage.

Personally, I think you're just trying to egg me on :p


and I don't know what circles you travel in, but 500hp aint shit these days. People have to be pushing more than 600 to the wheels to impress anyone anymore.

[Redog]

^^ Needing a cage impresses me ;)

[Spilner521]

and I don't know what circles you travel in, but 500hp aint shit these days. People have to be pushing more than 600 to the wheels to impress anyone anymore.
I don't know... An Evo that puts out 350-400whp and runs 11's with only a few bolt ons and a tune is pretty impressive.

[BlackJack]

might be to you, however, everyone knows an evo is supposed to be easily modded to that level, and well beyond. That leaves it far from the impressive bracket by my standards. Buying ready-made horsepower isn't impressive. Making something that isn't supposed to be that fast is more my taste. You get an Alero to stand up and roll some 11's and you get a round of applause from me. I'm not an import fan in any amount though, mostly because the ricer crowd has ruined my taste for it. There's only one import that I would consider owning, and that's a GTR, and only because I've wanted one since I saw one long before the term "rice" was coined, and you aren't going to see one on every corner when you drive down the street.

I still like your Evo though, it's very nice looking, and a well designed piece of machinery. I just wish the american manufacturers would get off their asses and make something like that again in the affordable bracket ;)

Until then, I'm going to keep modding what I have. Oh, and just so we get this straight, I've had my ass handed to me a couple of times and the surprise was reversed, but I've got a couple of tricks up my sleeve that should close the gap a bit.
