I have a p7100 pumped 4bt i am runnin in my 89 k5 blazer... well now that i have been drivin it around a while i am ggoing to turn it up... Does anyone know where i could look to see what this turbo is good up to as far as boost numbers go? like the hx35 is good to 35psi and anything over is just hot air... thats kind of what im lookin for with this turbo. I just dont want to overspeed the little thing and have peices of comp wheel going through my motor!
 
if i were you i would find a hy35 to throw on there. that little stock turbo has not much to offer on either side..
 
hy better than hx? whats the diff? it spool faster? thats the problem i had with the hx35...
 
The hy has a 9cm housing, the HX has a 12cm housing. The Hy will spool faster than the HX35.
 
some even had 7cm also single entry and pretty big gate. either would be my choice for up to 300+ on a 4bt
 
Buddy of mine is running a 351 on a 4BT Dakota, VE pump and 37s, still peppy, spools and tows well.
