WOW....so in decreasing the timing in this area we end up with a big "hole" in the table. Seems like that might cause major drivability issues.

I read the entire thread and there is mixed opinions. Any explanation of the effect your be appreciated.

not really its highly unlikely u will be @ 160 load at 5500/6000 rpm.

 

I really don't think you need to treat your street car like a rally car with antilag. Unless you have a monster turbo -10 is way way too much.

As for the AFR... it seems that the more fuel you add the faster the recovery. Again I don't think you need to go much more aggressive than stock.

 

I agree 100%. We use 160/180 load cells and rpm on high and low sides of 2step rpm. 8 in the 160 and 9 in the 180 is a good compromise for us. Tonight Indy made 16-19 lbs of boost in 1.4 seconds but part of that was the pulled timing due to knock causing more boost, causing more pulled timing, causing more boost, then launch and 0 knock. Less than 1 second is all we really need but hard to judge when to go for the driver.

 

Don't you mean the TME would handle the heat better? I was under the assumption that was what the TiAl wheel was created for.

*facepalm*. My brain got that one one backwards yesterday. The compressor wheel is weaker, not the hot side. You are correct.

 

No worries, but are you now saying the compressor wheel on the TME turbo is weaker than the factory VIII turbo? I was under the assumption that they shared the same compressor wheel. I could very well be wrong. Thanks.
