I am beulding a 13b that i am hoping i get arond 650bp ore so but i can't find out what turbo to us ?

Anyone have a propotion what i shud us

Thinking turbo of using a PT 68 whid 81 A/R ore a inovative 66 whid same A/R ..


thanx

 

you have got to go with a bigger a/r than that, you have to go with atleast a 1.0, I use a 1.15

 

That big .. when do it spol up then ? 5k ore somting i want to spol it up aboth 3k ore litle over ore somting ..

 

The only way I know to spool at 3000rpm with a large turbo is make sure it is a good ball bearing turbo and add a 50-75 dry shot of nitrous strait into the turbo not the intake and then hang on.

 

oki i see .. When do u think its maby going to spool up then ? 4000rpm ore somting ? If i go down on A/R its going to spool up a litle sooner but maby loosing much on top ? My friend is using a inovative 58 whid 81 ar on a 12A and he spools up aboter full boost on 3500 rpm .. He have 505 bhp at 1.36 bar bost .. Not to bad for a 12A
