If you look through all the 300kw hsv tunes with the callaway engine the early tunes are a bit more extreme in the idle department compared to the later ones. It’s good to see how holden tuned them over the years

Yeah I’ve played with tuning cammed ls1’s. It’s a pain cause once you play with one thing you’ll find your chasing your tail and having to adjust everything else. Main things like normal are more idle timing, higher idle rpm and than give it some more idle airflow. But than cracker/follower and all ...

I’ll wait till I get a manual loom to re-locate the pcm. Next on my list is some body work, wheels, turbo manifolds ect.

Well been busy moving houses. That’s finally done, and now time to start back up on the ss. Transmission left the building about a month ago in the ss after some spirited driving. The 4l80e arrived about 2weeks after though. But now I’m thinking I’d rather a manual anyway. Since the misses don’t lik...

Yeah probably a burner just in case. And I’m sure Dylan will chime in once someone says holden v8

From my understanding baro compensation is turned on n/a and turned off in boosted applications. Depends on what altitude your at, as to how much compensation is needed. But in a boosted application all that is irrelevant

Would be nice to have a play with some carbon fibre.

Well cold air intake was pretty easy to sort out. Went with the old ss induction setup. Over the radiator into large 4” outlet, dumped right at the turbo. Will just need to add an inclosed filter to complete that side of it

It really will be a sloppy mechanics build. Even the 45mm turbosmart gate is getting welded off the exhaust housing. The main thing I like about it all, is it’s compact kinda stock looking and proven for an easy 500-600hp.

Stock is only like 2.5” outlet. I’m using sch40 1.5” runners into 3” log. The log will drop down to 2.5” for the cross over. Nothing fancy just getting the job done.
