the S476r has been what, Bottom 5s in the 1/8? Im talking 5.teens

Go to the bullet and check the Ultrastreet section...

I don't think 60 ft is going to be relevant.

There are several people on this forum that have been in the 8s on either turbo. There are a couple here in the low-mid 8s on the S476R.

76mm turbos have been in the 7's on 3000+ lb V8s. A billet Borg Warner S476R with a 96mm wheel and a race cover should be capable of 1200 whp.

my daily type driver on a standard 475 t4 and a 302 with low boost went 1.58@60, 6.20@117.5, and 9.55@148. 3400 lbs, standard m/t 275, 3.25 gears... and mine is nothing special at all compared to what some guys are doing.

a 6.29 on a 1.5 60ft impressive for that 60. What stall speed are most these fast guys running any info? trying to run a class this year thats limited to a 76mm cast wheel turbo just making sure that im capable of mid 5s on the s475 or 76. keep the times coming

x235/Outlaw 8.5? That class is local to me.

Stall speeds in the low 3000 range are common. I don't think I've seen lower than 2800 or higher than 3800. I went with 3200 stall triple disk Circle D. I'm also going from a billet to cast wheel for x235, although I don't think I'll make it out this year since I don't have an 8.50 cert cage yet.

The S475 is capable of 5.60s without pushing it to the absolute limits. There are guys running mid 5.30s around here on a cast 76.

jason Rigney has been 5.16@138 and change with the S476R.... Matt Lawrence also went 5.16 with it.

Josh Castle went 5.60's with an S475 iirc.... might've been 5.80's..... car went 8.8X@153 with that 699 special.

guess the next question is what trans are the fast guys running? Im torn between a glide or Th400. I will half to do some searching on the s476R cast wheel.
