how to get more power out of a stillen supercharger kit?

ANMVQ

Who told you that? numerous people and tuners I have talked to said there is 10-20WHP to be added with TP's or HFC's,. Lets not count the numerous dyno sheets I have seen where guys are making 10-20 more WHP and WTRQ more than me and the only thing different they have are TP's or HFC's.

WOW mis-facts are nice. :/

You get the bonus from changing HFC's on an NA car but some say you loose it with an FI setup due to blow through due to valve opening overlap. I think there was some supporting dyno's for this theory but can't remember where.

In general or specifically on our engine? Check out the numerous GTM stage 1 SC threads, there was actually an entire thread dedicated to trying to get more power out of the SC with exhaust. Due to VVEL the intake and exhaust valve overlap is too aggresive for an FI application and causes us to loose boost through the exhaust. For example I'm running the 928 impellar AND the 9 psi pulley and I'm barely breaking 9 PSI on my Stillen kit with full exhaust

i used mustang dyno. wow the difference in our power is very big though hahaha

Mr.Squeeze

My power is on a dyno jet if it was on a mustang if I had to take a guess more in the 410-420 range.Sounds like you have a pretty strong car time for some upgrades man.

oh i see, then we are almost close, thats nice to hear thanks!

geoharto, I only made 400whp on a mustangdyne. Then I went to a dynojet and made 455whp.

Mr.Squeeze

The thing that bugs me about your car is your dyno jet SAE numbers compared to what my SAE number were.

well ive finally tuned it got some more parts installed, swift springs, whiteline sways, h&r spacers. im pushing 451 whp dont remember the torque 9.1psi, im getting some codes - multiple misfires, and o2 sensor codes. any thoughts?

Mr.Squeeze

I would take the car back to the person that tuned your car. Check the plugs for the misfires codes. If you installed test pipes without tricking your 02 senors this would throw a code for that.


Hey Reldas the higher octane that you use the better it will be to prevent knock.

The problem I see here is that if you tune for 98 octane you would have to always run that octane or you would have problems. And I have not checked the price of 98 recently but I am sure that would be expensive to run all the time increasing your HP to $ ratio.

i see alot of people tune their supercharge 370z with 91 or 93. is it ok to use 98? i would assume you would get better performance. also with the new impeller whats the difference between the clockwise and anti clockwise, and please dont say one spins clockwise and the other anti clockwise lol. which one suits the stillen kit?

reldas

i always run 98, cost me $1.50 a litre he in australia. 95 cost me $1.30 so extra 20c. is worth it

kellyefields

That makes a difference. here in the states 93 is what you find most common and to get the higher octane you must drive out of your way to get it and it also costs on average 1-2$ more per gallon.
