largest tb size on victor jr

[jammer84_03]

like the title says... i know the 75mm is what the intake is set for out of the box, but can it be opened up to a 90mm? or is it not that capable to be opened up?

No problem opening a Victor 5.0 to 90mm

 

[jammer84_03]

thanks rick. i figured you'd be the one to chime in...

another quicky. i opened up the ports on the gt40's i had. everything else is in my sig. could i look at a modest 40hp gain with the vic jr, and when i do the turbo open the tb up then, cuz it wouldnt make a huge dif now would it?

 

[Rick 91GT]

I dont think you'll see 40hp with only adding the Vic 5.0 your combo is a little on the "small" side to take full advantage of what the intake can do. When you add the turbo it will really come alive...your heads even ported will be the bottle neck. Id leave the TB opening alone personally, even when you do the turbo unless you upgrade to a larger head.
