Thats exactly what the question I need to know.
How to build boost faster??

I am running Hondata 2B, with a Greddy Profec B spec-II, and an Apexi Turbo timer.
Thats about it for electronics.
As for the motor
D16Y8
Built Bottem end
Comp Cam
520cc Msd injectors
Precision SC50
Other goodies as well

It has been tuned to 9psi as low boost and 15psi as a high boost setting. It takes a while to even hit 9psi as far as 15psi goes, I havent hit it yet.

Anything I can do to solve this problem??

 

what exhaust? what manifold?

 

Skunk 2 exhaust
equal length mani

 

bigger exhaust
bigger downpipe
3 inch testpipe

 

you get automatic props form itsme4g63 for turbocharging you sohc

 

Thanks
Downpipe is 3in
testpipe??

i have a boosted sohc...
give me some props lol

 

-more displacement
-higher compression
-smaller A/R on hotside of turbo
-decrease size + length of IC piping (marginal)
-smaller IC (marginal)
-nitrous

 

ok
what can i do with my boost controller?? anything??

when are u reaching full boost?
i have a precision sc50 .63a/r and see it reach full boost in the 4k rpm range (somewhere in that range)

 

not around 4k thats for sure, I wish it was around 4k

 

The only way to build boost quicker is to slap a nitrous kit on there. Im running a 35shot with my turbo set up.. Plan to shift fast...

There has to be another way

 

you can also set your gain higher and it will spool quicker but make sure you dont overboost!

 

How do i do that??

 

what wastegate are you running??? Is it leaking???

 

check for boost leaks.

 

with a 3inch dp... you should be spooling...

i'd 2nd the check for leaks suggestion. I was getting great boost response before... replaced a random coupler that turns out to have been leaking a bit. Now my spool is even faster.

 

are you tuned in the lower boost levels? when I do cars starting with .9 or .8 degree per PSI and then change to a step retard with little or no timing taken out to 3 PSI I noticed at least 200 rpm faster spool and sometimes up to 500 rpm.

 

Switch to a ball bearing turbo :-D

Anyways, definetly check for leaks in the system, and look for any restrictions. A test pipe (cat delete) will give you a quicker spool. A smaller turbo will spool quicker, but you'll lose top end.

 

could some of your vac. lines be TOO long...or hooked up wrong?

 

Up

 

tial wastegate

 

read the manual for the profec spec 2; it tells you how to set the gain; start boost and all that ****.

set the stat boost higher or set the gain higher; there is so much **** you can do with that boost controller; just read the manual and test it out.

It doesn't sound like you have any problem with boost spiking so your wastegate is probably opening way too early
