whats the limited speed for the g35c?
do you need like a ECU chip like BMW M3's which are limited to like 106 mph??

also how much hp would a supercharger add to a 2004 automatic g35c?

 

156 MPH, electronically limited.

I've hit 160 (actually a little past but our needle is the kind that stops at max instead of winding back) with the Technosquare ECU (which allows for this)

Id estimate the top speed of a stock (non goverened) G35 to be around 165 MPH. My setup, with the added revs and hp, approx 170-175.

Most 6MT S/C'ed G's with proper tuning put down about 400-430 rwhp and 300-330 rear wheel tq. The tuning is essential to break the 400 mark though. As far as an AT, shave a little off for the added drivetrain loss (if any as the AT"s in the G are actually very, very efficient in comparisson to other MT vs AT of the same type of cars). Hope that helps.

More mods to come....stay tuned.

 

ah ha.. thanks.. so about 400 rwhp thats pretty sexy for only a super charger upgrade... then u get the basics like intake catback and a few little things
