So what exactly is wrong with the Stillen SC kit?

The stillen intercooler is very ineffective, the location of the ait and maf
Is not good and it greatly limits the power of a v3 vortech head unit

Yes you can start replacing stuff like custom redoing the pipes to install
A fmic or get a better impeller but after the money I spent I was not going to go that route

I was seeing about 230 oil temps but thsts not the only factor when timming is being pullef
I went to a 9lb pulley and was seeing about 10psl at that point my water to air intercooler was not cooling my charge air
Ait was reading one thing air going in to the motor was way hotter
A simple fmic would have helped a lot

If you keep the kit I would upgrade :
the water to air heat exhange
Run a larger water reserve and move it to the trunk
Upgrade the impeller
And move the maf closer to the tb
Change over to cog pullies
And run water meth
Retune

At will get you real close to 500rwhp
