first time doing forced induction on any car im about to jump on a used stillen supercharger used for 6k miles can you guys tell me anythings to look out for.

and the guy told me i dont need a dyno tune since it comes with a stillen tune can someone confirm this?

 

I wouldn't buy Stillen's SC. Their tune is terrible too. It really takes a custom tune to run right, but the entire kit is inferior compared to GTM's offerings. If you are looking to save cash, find someone willing to sell their GTM SC setup. The stage 1 GTM kit makes similar power to the Stillen, but power ramps up faster, it's quieter, and the canned tune is worlds better.

 

i have the stillen kit....i would suggest if you buy it to install it and have it tune professionally... their tune does suck major ***** because they made it 50 state carb legal... however i dont care for anything that gtm has made just my personal opinion nothing against gtm im sure they make a good product just would rather go with greddy or hks for anything forced induction... with that being said the above post is correct their supercharger system is in fact pretty silent but depending on the deal you get its completely up to you...

 

Do it right and get a turbo.

 

the thing is i wouldve went gtm or twin turbo but im limited to options because im all the way in canada and shipping and duties would be killer. the used stillen supercharger is bein sold by a local

and if i go stillen i will get an uprev tune right away

 

I see, that makes sense then

 

idk if the have E85 up there in canada since the last time i went there i was 15 and it was for hockey but up grade the fuel rails and ID1000cc injectors and get it tuned for that youll get a lot more power than just pump gas. Just a suggestion

 

no i dont think we have e85 up here i usually just put 92 octane

 

Nothing wrong with the stillen kit (hardware), all it needs is a good tune.

The fact that the seller told you that you can run it on the Stillen tune would be enough to scare me off!! He either has no idea what he is talking about or is trying to convince you that his kit will be cheaper! Either way it sounds dodgy!

As mentioned above, wait for another kit and DEFINITELY get it tuned. Every car is slightly diffrent so needs its own tune to get the most performance and more importantly, safety out of it.

 

Agree with jersey G37 , you couldn't pay me to buy a GTM product , I made good power on my Stillen (412 WHP) then modded it to a STG 2 and made 457 WHP and this was on a X coupe. Stillen is fine just get a custom tune

 

if the supercharger been used for 2 years 25k miles should i pass on it?

 

I like new, when it comes to mechanical parts.... Well.... All parts, but particularly mechanical parts. You never know what some moron has done to the parts they are pushing.

 

i mean two year old with 25k on it i would really have the super charger checked out prior to you buying it by either stillen or vortek just to make sure the inners of the supercharger are good, you never know sometime barrings go out.... just a suggestion i got mine brand new just so that i didnt have to worry about it

 

I like the Stillen kit a lot. A few locals here in Miami have made excellent numbers from a great tune on 93 octane and E85.

Good luck with your decision, just be sure to get it checked out prior to purchasing.
