here is the dyno of the car using a 1 bar spring only the wastegate not boost control for the 1bar run. the other run was running 1.3bar using a profec b spec II and a few other mods...

1 bar 385rwhp
1.3 bar 475rwhp

im trying to find the 499rwhp chart we did on 1.3bar, once I find I will post it up

enjoy


comments and questions welcomed.

 

Holy lord man...

 

nice numbers

 

yea, thats just sick.

but why the HUGE jump in performance from just .3 bar? i mean, it went up almost 115 hp from just that little bit. doesnt that seem odd?

 

its a big turbo +4.35psi. i thought it was a lot, but didnt seem outrageous. it actually went up 90.1whp from the 4.35psi increase, then later hit 499.9 (i assume there was a bit of tuning). so i imagine the lower number would increase as well.
so, roughly, 20.7hp/psi. doesnt seem too huge compared to the size of the blower pushin the boost.

 

at 1.2 bar the turbo is just really starting to get into the efficiency zone.



casio where is the new signature you are talking about...

 

here is the compressor map for my turbo

 

 

thanks man. cool sig.

 

with the 1.0 bar graph. what is the hiccup at 5k?
