No 50% gain - about 80 HP. That's expensive horsepower!
Exactly. However, the HP gain is off the rear wheels. At the flywheel, its more like 100 hp. Also, Stillen offers 4 different grades of supercharger for the G35. This may be the basic package, with different levels of boost, etc. available above it for a couple hundred bucks more. Looks like a 6 psi boost type. You could probably go 8-9 PSI if you make it premium only for example and get another 40-50 hp from it.
Allow me to plagurize from a TitanTalk member:
Stillen had this to say about the s/c:
RESPONSE FROM STILLEN -
This is in regards to the recent Stillen Supercharger issues discussed here on the forum. Please understand that this project is nearing completion but performance numbers and pricing must remain preliminary at this point and is subject to change.
At present, our Research and Development team is in final tuning stages of the system. Our preliminary power numbers (as registered on our Dynojet dyno at the rear wheels ) at this point stand at 387hp and 418 torque. This is an increase of 110 hp and 84 ft/lbs over stock at the wheels. (For comparison purposes please note that these rear wheel numbers equate to 425 hp and 475 ft/lbs at the flywheel.)
Also, its important to note that we have tested numerous production Titans from Nissan in order to get a firm base line to judge against for stock performance. What we have found is that stock Titan horsepower numbers have varied from the mid 260s to mid 270s. We are using one of the higher base lines we've found, hence our data moving forward will state increase against a base of 276.
On another related note. The STILLEN systems not only provide the stated gain in horsepower, but the system has been developed to provide "through the powerband" increases, not just upper end. This has been true with all of our supercharger systems. The STILLEN superchargers will also offer an optional 3 year 36,000 mile ENGINE warranty along with CARB pending status until such time as we receive CARB certification.
Look for more detailed information on our website at www.stillen.com
in the next few days.
I'm in wait and see mode. :hmm:
