Wait... nobody pointed out the missing bolt on the TB??? suprising!!! (TB spacer; needs a special bolt longer than I have)

 

dam ur crazy

 

tuned to 18.5PSI in short bursts no 4th/5th gear pulls to prevent snapping rods; still hitting boostcut very fast... need to work on the flapper valve before turning it up more on a stock motor

Oah yeah, and rich as **** above 12PSI. (high 10's, low 11's.

wideband is crappin out on me for some reason; seeing consistant 10.0:1 AFR.. so I need to get it solved pronto!

good news is a vacuum mod to the bypass valve is helping, but it needs some more work; a bigger valve.. I need an OBD2 PCS pronto!

 

WOWWWW....That is a solid homemadeturbo kit. Get oil lines from stealthmode. Seriously consider a DP. (Downpipe not Double Penetration)

Also a Blow off valve, and an Intercooler would be good ideas.

If anything I'd say you are half-way there.

Edit: Wow, this post is old. Good job

 

Hahaha, I decided to dig up the thread and see how old a reply was....

And saw all the pics were broken.


Fixed the pics.

I sold this car a long while ago...

Scattered the OEM bottom end with the setup in my buddies garage tuning antilag.... I knew what I was doin...


Anyways.... new project sol coming out soon...

Major body work is almost done..






Back from the dead yo!

 

lol is the sol gonna have the setup this one did?

 

I'm starting with a z6, which is what the si originally came with. I want a jdm d15b, but no funds for that route yet.

I will start with a hmt grungy turbo kit again... Get a feel for the sol boosted, then get a supercharger, run and tune it, then add the turbo kit back on and shoot the moon. I have an extremely inginous plan to fix the overboost issue:

if the sc was pushing 6.5psi, then the turbo hit 6.5, the sc would add a multiplification to the plenum actual psi amounts. About 42.42psi if nothing is lost/gained in temperature changes. There is a vacuum operated valve in the charger to bypass pressure as needed to keep it from overboosting. Since the turbo completely negates the vacuum signal, it will not function. This is a big problem.

My idea would be using a purge control solenoid, and a vacuum chamber. The vacuum chamber would have 2 ports on either end, one end with a one way valve to the plenum to only allow it to be vacuumed out, and the other port/end to the PCS, which hooks to the bypass valve.

When load is low enough mbars, the pcs is open letting vacuum to the valve (normal operation), and a high load activation to keep from overboosting. The pcs will close and enable boost as needed.

This is the simplest solution, but will make boost more like an on/off switch based upon conditions, rather than a linear change as you increase or decrease load.

If I use a vacuum pump I can think of using a boost controller on the flapper valve.... Which would fix everything I believe... I am trying to find a good solution to my dilemma without doing a bunch of retarded hanky panky.
