here is the setup:
ls block, stock sleeves (block guard)
81.25 je pistons
9.1:1 compression
eagle rods
balanced crank
type r head, cams,
edlebroke intake manifold, port matched to head,
skunk2 springs,retainers and cam gears
msd 6al
drag turbo kit
550 injectors
s100 hondata
the turbo is a t3t4 ( .57 trim, .63 A/R)
tail wastegate 9psi spring

what do guys think about 20psi with this , assuming that injectors supply enough fuel

 

with larger injectors yes, doubt it with 550's

 

the anser is NO!. why. don't ask you won't like the answer

wow im sure he will appreciate all your help.

to answer your question.. yes its possible but i would say that you will need larger injectors to make that happen. At 20 psi on that turbo you should be close to 400 whp and that will most likely put the 550's at 100% duty cycle. But just go to the dyno and find out for yourself. you cant obviously just turn it to 20 and go. Tuning will be the key. HTH. CHRIS

Edit*
A guy locally here runs drag turbo kits on many of his setups and i know he has pushed a few of the cars to nearly 28 lbs. I dont know if the turbo is even efficient at that level but ... its been done alot. off course that was with some sort of engine management

 

yes. with the proper tuning but 20psi can mean a lot of things depending on how agressive the tune is. 550cc may not be enough

 

still would like to know, that why i asked!!

thanks everyone for ur help

 

On the drag website, http://www.dragturbokits.com , you will see that he states that the turbo is good to 25 psi and I beleive it was 450hp. Go look and see for yourself.. the psi number i'm positive of. If he's right, that's another story...

Let me take a wild guess......Eagle rods?

That's not my personal opinion but it seems that a bunch of people here don't like the Eagles.

As for your question. 20 psi is a lot on 550s. I know of a guy running 720s on his 367 hp civic tuned by an AEM EMS, and while in boost (1 bar) it holds a perfect low to mid 11:1 AFR and he was maxing the injectors at an 86% duty cycle. That to me would say that 550s would run out of breath.
