dinan or aa?

[speshuled619]

well ive been doin some research oh the superchargers from both these companies, but i would like to know what the poeple that run these systems think about them. what are the pros and cons of the 2? why would one be better than the other? also if i wanted to down the road which system can i upgrade to achieve more power?

AA for sure. Then take the extra money and get yourself trackpipe and exhaust, ,maybe even some good ltw wheels of other performance mods.

I don't know what extra money you're talking about... a Dinan SC for his '95 M3 is about $5k, I believe. Whatever it is, it's very close to AA's price.

Ok, as a previous AA SC owner, I'd say go Dinan. But, it also depends on what type of driving you'll be doing as Dinan can heat-soak. Dinan will also allow for more boost, power, etc. Power wise, an Intercooled AA SC dyno's the same as a non-Intercooled Vortech SC... so that should tell you something right there.

Now, as an enthusiast, I'd say don't go EITHER. Either wait for the Eurosport Twin-screw or one of the turbo kits. It all really depends on what your goal is and how much you can afford.

i think the dinan blowers are alot more then "about $5k" last i knew at least.
But hey maybe i am wrong?

Ok, I was off a bit, it's $5495 :). Besides, I've heard of people getting discounts on those from the dealer anyway (maybe BMWCCA discount, I don't know). I'm sure it could be had new for $5k.

My bad I always thought they were twice that well I guess go with that one that makes more power. I dont have a blower so I cant really say I just think AA makes great products but then agian DINAN is DINAN so you cant go wrong either way.

as a previous aa owner why do you choose dinan? what bad experiences have you had with aa? i mean aa does come with the intercooler and oil cooler. dinan doesnt come with any type of cooler.

yeah ive been reading about the twin screw but really would it cost a lot more for a setup like that?

i would really love to go turbo, prob putting a kit together myslef. ive put together a turbo kit before on my previous car. i fab'd all my pipes and down pipe. but i dunno if i wanna go that route again on this car, i mean theres less parts in a s/c kit than with a turbo to worry about.

The story of Boris is very long... and it has nothing to do with bad experience (i think), its just the AA SC is not for him (AA SC not upgradable for hi boost).

Im a current AA SC owner, and i can tell you, its top quality... no problems so far (knock wood), and lots of power...
The AA SC is great if you plan on sticking that power level... a bit can be achieved with a "little" pulley (1 or 2 psi more), exhaust system, and other type of mods... but the Vortech SC can handle more boost than the rotrex...

If you plan on going hi power... ill go TURBO... if money is an issue, go ATP Turbo Kit hardware and Nick Software or AA Software or Unichip...
The next option would be twin screw... if not... then i would go AA SC, for a great reliability...

Good way of putting it! The 'not-upgradable' part was definitely a big issue.

On your 325, MAYBE. On an M3 the SC is MAXED OUT. I mean so maxed out, I couldn't even get an extra 100-200rpm of rev as Rotrex would effectively drop my warrantee.

I thought one of the concerns the original poster had was the ability to upgrade. There is absolutely ZERO upgrades you can do at this point with that Rotrex (short of other boltons or cams, etc). Vortech can support more boost if you need it, thought.

oh wow.. i was wrong :)
they're kits use to be alot more when i got my ess charger about 2 years ago.
And AA's stage 2 i just got was cheaper then too :mad:

but thats good news on the s/c :redspot

Yep Boris, i know what you mean...
I really dont have real experience with the M3... but in my 325is... the SC is really good... i tested the other Day with a EURO M3... and he has no chance... and im running with a bad pipe (bended by me the wrong way, AA sent me the correct mandrel bent part) that is taking me 2 psi... im runing 6.5psi at max rpm (6500rpm)... imagine when i put the correct pipe with 2 more psi... its really great for big power and GOOD reliability... but as Boris stated... no upgrade for hi boost...
Vortech would be the choose (or Twin screw) for hi boost application...

If i would do over again... i would go AA SC for daily drive car... or ATP Turbo kit for track/race car...
For the price of the twinscrew... a Turbocharger is the best way to go... unlimit upgradability... :)

Well...as an AA owner I agree with alot of what Boris has to say. I agree that its so far (about a year) been a solid kit once I got over initial troubleshooting issues. I haven't had any belt issues like other AA owners, the only thing that annoys me is the leak on the oil return line from the supercharger.

It a good kit and for $4K, its a really good kit.

But if I were someone in the market today I would wait another year and see how this twin screw charger turns out. Be patient cause I can tell you 18 months ago when the AA kit was coming out there was all this hype..AA was going to be the best, it had an intercooler, yada yada yada...the kit came out I think it underwhelmed people and today we're talking about twinscrew. And you really can't form an opinion on a few beta testers you need to wait for the first run to be distributed and get more unbiased feedback.

yeah being that the aa is hard to upgrade did come across my mind. although im not even sure yet with what power i would be happy with. you guys said that the aa for an m is maxed out already, but it was also stated that they have a smaller pulley available for the rotrex, now using this pulley on the rotrex is that advisable or not? and for dinans vortex how reliable is it being that it doesnt come with anyting to cool down the charged air? is it something that i would need to look into water injection?

who is atp? what turbo kits do they make and how well are they? id like to know more about this.

thanks for all the info and replies. this is helping me out.

[JLee]

Well the Dinan kit is definitely reliable, you will get heat soak, but the kit itself and its performance I think is reliable.

Whereas AAs kit doesn't have the reliability record yet, it just hasn't been around long enough. But for $1500 less...I figured it was worth the risk.

If your looking for "more power" you really do need to just save and wait for the twin screw.

Like the post above said, the AA kit is a great s/c for a daily driver, steady, linear power..nothing earth shattering

There is also another option, you can contact AA and see if it is available to run the larger Rotrex unit used for the E46 M3 kit on the E36 M3 kit.

[GQ_Style]

For me, a major factor was installability by myself in my garage. The Vortech has slightly more complex oil routing and feeds off the engine oil supply versus having its own supply.

I think the AA is great for my purposes. I have no intentions of upgrading this kit nor do I have plans of doing other upgrades. I only want this to be a great daily driver that is stronger than your typical E36 M3. I don't want to be the fastest or strongest, nor do I call people out to race. This kit works great and is reliable for my needs.

They have a 330ci E46 with the turbo kit...
The hardware would be great... dont know about the software... i would go standalone or unichip... or Nick G/Karl@AA custom software

They will work with the GT-30R or GT-35R if you want...

They have very goodreputation with the VW/Audi people...

[speshuled619]

oh alright yes i have heard of ATP. they are known for the vw/audi products.

i also never thought about seeing if the bigger rotrex from the e46 would work on the e36. hmmm.

well anyways yeah i guess first things first, i just need to see what my needs are. i need to find out what hp ill be happy with. i guess that should be my starting point.
