I’m not sure what builds you’re talking about. Most I’ve seen over there aren’t even up to a proper Renesis; 220+ whp. They should be better though, but those that are be few and far between …

All these guys throw the kitchen sink at this engine. Less is more.

Been saying it for years ..... GLSE housings , Renesis ex. ports blocked at the plate, equal length tuned exhaust and custom UIM ..... done! BP for braps if desired.

more like BP for craps

blocking side exhaust ports has consequences though, there is no real solution for that other than custom side plates, which again coupled with the full side primary port opening at 3° ABDC, people just aren't understanding the true physics occurring with the 13B housings added …

Post 286 is the most recent dyno run. Looks like he potentially warped his seals due to running too hot of plugs.

Why would think that build was anything special? PP engines regularly run up to 300whp plus.

Even to a simpleton such as myself, the evidence seems clear time and again that the hybrid msp is not practical. Imo, just accept the msp for what it is and for those who crave "more power" to consider the pros/cons of swap.

I had a discussion with this gentleman about his engine for sale some years ago. This is one of the "better" 13b n/a setups I've seen over the years albeit on race gas.

I tried to tell him in the comments that the 5 exhaust port setup was never going to work.
He's first hybrid youtuber to actually admit failure and deserves some credit for that!
