Stillen Supercharger reliabiity

Boosted Performance

I am not trying to compare the two at all. Each has it's place....just wanted to correct the fuel consumption theory.

not always, maybe the centrifugal ones, but the roots style Stillen that I had on my 350Z had a vacuum operated bypass valve that relieved the pressure on the compressor when not on the gas hard.

Boosted Performance

Yes, always. In order to have air to recirculate, and relieve the pressure, energy had to be spent on generating the pressure in the first place. This comes from the engine, and is the reson all superchargers have bypass valves, and not blow off valves. If they had BOV's, it would constantly whistle, as it tries to vent the air/pressure being generated by the blower.

To be more specific to the supercharge you are refering to, the Eaton M62. In order for it to make 10psi of boost, spinning at 12,000rpm it needs 42hp. I know these superchargers very well, because I used them on some kits I used to build for a different platform.

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

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!

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.

Since this is my daily driver, I agree with this. Can anyone identify what the base cost of having this completed runs? I'm guessing about 8k?

$8800 for me, but I paid full price for my kit from Stillen, you might do better and the install was high as I was the first 2013, so 8K seems doable.

Coon-azz

thats some serious $ for as problematic as this has been for you; which I'm sorry to hear. this is exactly why I've stayed away from this option so far. If I dish out 8k, I expect to pick up my car working perfectly.

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.

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
