Don't some superchargers have some sort of bypass in them that would account for that? I guess with a turbo that large it could cuase some issue.

 

There's slim to no extra cooling to be had past 11.5:1.

Can you log coolant temps? Do you have det-cans? Can you fiddle ignition timing? These things are more important, IMO.

 

I am running it so rich because since I am rough tuning it right now, better rich than lean!

I am in the process of getting a probe installed in the intake.

I will have a knock link on Dyno day

Yes I can pull timing, currently pulling 4 degrees, but I did this automatically, I may not need to.

I am running about 100-102 octane right now.

 

Way to take on a project! Interested in seeing the graph you make on the dyno with this setup.

 

Very cool setup... lots of good work you've done.

 

The only other cars I've seen with twin charging are, a Mini Cooper, and Grand Prix. The Grand Prix runs mid 9's all day at Stanton Dragway in Mi. Last time I seen him run he did blow a coolant line but didn't have any other problems the whole day. Seems like a sweet project, don't let ---- talkin' e-thugs get to you.

 

I bet your motto is "Don't talk about it, be about it."

Good work.

 

Note to everyone.....


If you run a rrfpr, you MUST use a clamp on the return line.... Even though the fuel return line for subarus is pressure fit, 110 psi is a tad much for it to deal with! The fuel return line popped off at 18 psi and I smellt ALOT of gas..... Needless to say I pulled over immediately and turned of the wagon.... I was one lucky ****** I didnt burn up. Gas everywhere but the turbo thank god.

On another note, I can't seem to get over 18.5 psi.... I am hoping its the BOV spring. I increased the spring strength some by installing about 4-5 washers.. Its a Turbo XS brand.

So, if I am stuck at 18.5, I should dyno at 265 whp, 290 torque.....

If the spring thing works, then who knows what will happen.....

 

good luck with the spring, however I am betting that it's the SC--at those boost levels it becomes a bottleneck. Eventually you will have to make it a pneumatic system, so as to have all the topend that turbo can give

 

Yeah, eventually I will go to a bypass system. Eventually.... I need the money, time and parts... I have some other issues I need to deal with soon for my brothers car and so will need to lay off mine for awhile.
