Putting on the ks doesn't have to be boring. Took her over to the beach for a swim this evening.
Learnt a few things:
*I can make it pulse like a bridgeport REW or idle just like stock ...just by changing setup and tune.
*Runs almost as smooth as stock in general driving
*Fuel comsumption looks like it's going to be at least as good as stock if not better.
I've probably milked this for long enough now so here goes .
Technical details :
It's bridgeported and has small peripheral exhaust ports ................. so there is a **** ton of overlap but relatively small ports. Not terribly exciting but should make a difference.
Will start by venting the PPs to atmosphere (not as noisy as you might think because they open so much later than the side ports) and using the wastegate to control when that happens.
The mod I've done wont be that hard to implement for others............. if it works. It took me several hours with a die grinder plus there is the machining which I couldn't do without a mill.
*Stops all the "that wont work" and negative banter .... (see my turbo thread for example)
*Prevents idea from being copied by fellow enthusiasts before it is properly tested.
*Prevents it being copied by tuning shops and promoted as their own idea.
So it makes sense to keep the details sketchy . Even now I'm sure there will be some people that have figured out what I've done as I've given most of it away and it's just filling in the blanks. But i'm close enough to actually testing it now so not particularly concerned.
Also : going full MM would mean throwing in piles of BS ...and I'm not into that.
I don’t want you to misunderstand what I’m saying. If those were your reasons then having started this thread makes no sense. Except for the “I know and you don’t” game, which seems like the repeating theme here. The fuel pump and dwell table topics come to mind.
Do i get a cookie on being the first one to predict a peripheral port, albeit slightly different? I did delete the post though as to not spoil everything
Can i start drilling on my engine while it is in the engine bay? On the sides right?
Looking forward to more videos. Nonetheless this is very interesting Brett.

Here is your cookie ....now don't eat it all at once !
Brett, Som real talk...aside from the brapppaage, which of course isn't worth the effort..., what's the benefit of overlap in an NA Renesis?
I certainly see potential in a FI application.
You know what vtec is right ?What i'm doing will be similar except i'll be turning on the overlap at the desired rpm with a wastegate vs with cam angle change. In general though large overlap is better suited to N/A applications unless you run a huge (laggy) turbine and have emap lower than Imap.
BTW .....this engine will barely run under 2500rpm with the pps left open .... In fact it goes super lean ,indicating that air is actually being sucked in though the out tube !
That's your opinion and I don't share it ................. which is situation normal around here
... just like you didn’t share that you’re as guilty as anyone for doing what it is that you mention about your turbo thread. Funny that you didn’t mention the threads where you’re that person.
Now the groupies rush in laughing along with you, just like the good old MM days. Ok then ... wishing you the best for achieving your goal.

yeah, it’s likely to oscillate in both directions. Bet you weren’t prepared for that and what it will likely end up meaning ...
