Stillen Supercharger reliabiity

SharpByCoop

BHP = ^^ True. But ONLY a factory with an engine dyno can verify 'crank' horsepower. Separated from the chassis completely. Unless proven and documented, it's purely speculation.

Rare to have these resources, and WHP figures are substantially easier to verify and replicate. Engine HP is a great selling pitch.

This said, the Stillen product has been providing owners with glee for years. Good going!

And it was an over priced POS for the little power it made.

Okay - so this was my mistaken interpretation from an early conversation with a Stillen tech.
However, I spoke with my primary rep at Stillen today. He says there is no Break in time for a Supercharger and if the tech is satisfied with the install the car can be run to redline for a dyno pull the same day as the install. The guys at IPS agree so hopefully the car will be ready to roll today. I will post the pre and post dyno numbers hopefully by tomorrow but if the car isn't ready tonight I won't be able to pick it up until Thursday.

advice get a good tune. the stillen kit will serve you fine but its not make for any real power with out modification the head unit is a good unit and makes good power but the kit with water to air cooler and maf positioning limits the head units power with out modification

i will post my dyno numbers today or tommorow

436/340 @ 9psi

i added water/meth and cog pullies

numbers will be added

and if i dont go turbo next year i iwill add longtubes,ysi-trim and move the maf behind the blower with a new intake pipe

Good read in this thread and nice numbers Nissan370

As much as I love turbo I have been leaning towards a Stillen Supercharger myself just in terms of reliability, maintenance and cost. Not saying a Turbo can't be as reliable, I just imagine the SC to be more forgiving in that aspect.

Id be happy with power in the 400-440 WHP and mid 300's for tq

seems like a good tune is key no matter what application you go with.

The stillen SC is pretty enticing...

truce me guys once u get some power your going to want more
anyways if my money looks good around march-april time frame i will be selling the kit complete (injectors/fuel pump/cog pulley/ect) so keep me in mind around that time if your going to buy lol

but if not i will pull every trick i can find to get the max out of this kit
main problem i see is the intake is way to hot doing summer weather
i mean its crazy how hot that thing gets larger heat exhange and coolin container is needed

the car was pulling timing on me because the intake air was getting so hot
and because the maf meter is before the blower its not reading the correct intake temp.

This ^^^ well said!
It's proven, just like with money. Once u get some ur gonna want more! Just keep in mind ur power goals and leave yourself room for growth later on! There is no feeling like a turbo kit, once torque kicks in its just an adrenaline rush. Jus go for a turbo kit n run low boost. When u want the extra power (and u will) u can always turn it up!
Don't end up buying 2 FI kits! Do it right the first time.

elperuano

Be careful trying to max out the kit, if the car is pullin timing for overheating on the intake I'm sure the motor doesn't like that. Might be causing problems and the ecu is tryin to keep it safe. ANMVQ had his motor pop and although I'm sure it was install botch I'm sure the extra runs and the stress on the motor with an over stressed FI kit didnt help.

Nissan370

thats one reason why my tuner tunes the car hot since the ecu does not know what the temp. is going into the motor til it detects knocking
u dont want that great dyno number when the car is cool then go to race and not know the ecu is pulling timing and your making way less power

just wish i went turbo from the start but we live and learn some times you just have to make the best out of what you have ask the woman with no arms she can make a cake with her feet

Lol!
I'm not sure about doing dyno runs in"cold"? Maybe u mean with those big fans on the intercooler? It keeps the engine cool while tuning but it also simulates street tuning as if ur driving on the street with regular airflow.

EVOHUNTER

This still will not fix the weird MAF readings, The MAF's will still be before the intercooler, So the maf/s read before the intercooler, once it hits our intercooler the maf readings change.
The only way is to dump the air to water kit and move to air to air and scap that useless intake mani.
Me and sasha are going to look into it in the spring time.
I love my stillen kit, But when its hot out -80-100 degrees The cooling system can not keep up.
Pulls alot of timing.
But over all after a good tune, the kit is great.

we were looking at doing some kinda split pipping after the blower then your maf then into your stillen intake

the combo of using water-meth and upgraded to the water-air cooler should be fine
