Supercharging a 07 GT - what gear ration ?
Hi guys,
I'm installing the Ati Stage II Procharger on my 07 GT at 10 psi, so about 400+ rwhp. What gear ration should I go with, drag orientated ?
Also, what oil do you use for the engine with a supercharger setup ?
thanks,

Everyone will mostly say 4:10 but my 3:55s were perfect when I had my paxton 2200. I was puitting down 430. For the daily driver it was fun! Even with 3:55s I would get sick of the ocasional spin in 1st and 2nd. But if you like breaking your tires loose go with 3.73 or higher. I have eibach lowering springs, steeda shocks and stuts, bmr lcas and nitto 555s 274/40/18.

my friend has a vortech and he likes his 4,.10s to build boost quicker and make up for the lack of tq the centri sc make. when the saleen goes on, i will try it with my 4.10s but will most likely switch to 3.73s.

I'm sticking with my 3.55's on my Kenne Bell. running a centrifugal I would think the 4.10's would be best to help keep the rev's up. personally I like the 3.55's to keep the revs down on the highway for longer trips. my buddy had an 04 GT with 3.73's on a KB with 425whp and that was pretty nice, any higher and you would just be shifting like crazy.

What would be the top speed penalty loos with a 3.73 compared to the original ?
Also what spark plugs should I go with the supercharger ? One step colder iridium IX ?
Any other mods that you would recomand going with the supercharger ?
My list is:
- long headers, full 2.5" exhaust
- 3.73 gears
- ati procharger stage 2
- lowering springs - What brand should I go with: Ford Racing or Eibach or H&R ?. Do you know if the Eibach drag kit drops the suspensions or it sits as high as stock ?
- 18x10 rear wheels.

I have 4.10s with my Saleen Twin Screw, feels like a perfect fit. A lot of people recommended both 3.73 and 4.10, and even 3.93, but I ended up pushing for the 4.10s. I think I made the right decision.
