I got my hands on a 1320 performance prototype header for the h22. They’re not in production yet but they are supposed to be at some point.

Some footage from Summit Point
The car was just put back together before this event. This is my first event driving on the Fortune Auto 500s, first event running the Mfactory helical racepack differential, and first event on toyo RRs for me.

What's with the jumpiness in your speedometer? I would have guessed maybe wheel spin, but it's happening even on the straights.
And how are you liking that header design compared to the Bisi rep? Notice any change in power band? This prototype looks exactly like the PLM tri-Y I picked up for mine after seeing that PLM changed the design a bit in their Bisi rep in a really bad way.Last edited by CyborgGT; 02-24-2019, 04:22 PM.

And ideally for road racing in a class where I have a hp limit, the 4-2-1 should yield weaker but broader pulses back to the exhaust valve giving me slightly less peak but a broader powerband. I will certainly update when I get the car back on the dyno to see if it works out that way or not.IG: H2wagon

That is an entertaining track video. Are you running a baffled oil pan?
I worry about oil starvation and oil pressure drops during track driving at HDPEs. I have contemplated adding an accusump unit or having a baffle welded into my oil pan to mitigate the potential occurrence. But both of those might be overkill.

Not just 4-2-1 = broader powerband. I guess what I’m saying is the science behind the design is a lot more elaborate and to actually squeeze out a wider powerband the pulses need to hit the valve at the right time, which relies specifically on the pressure in the runner, which is directly related to the length of the distance the pulse has to travel as well as the volumetric capacity of the runner and the size of the collector
Nice setup btw.Originally posted by wed3kim a douchebag to people and i don't even own a lambo. whats your point? we, douchbags, come in all sorts of shapes and colours.

And she holds her own pretty well. right around 200whp and without driver the car weighs in at around 2560lbs.

Yes, sir. I have no excuse for failing to do all the math myself, but I got such a steal on the header and my tuner is like 15 minutes from my house so I'll be posting a dyno graph for both headers soon. It should be pretty applicable to many with H22s as my engine is completely stock minus the balance shaft delete and s2000 throttle body. The prototype is supposed to be going into production in the next couple of months. also, thank you. I've had the wagon since 2011 so it's been a work in progress for quite some time!
I appreciate all the love. It's the most fun car I have ever driven by far. And a side effect is that it is quite the conversation starter at the track haha.Last edited by wagon.spec; 02-26-2019, 10:44 PM.IG: H2wagon

Man, what were those German cars doing in the Honda Challege?
Dude, things were going so well, and then...snap
You weren't able to engage any gear after that? It's weird, I guess I would be able to know more if I was driving at the time. Have you taken the trans apart and looked at the input shaft?*** Think of others before thinking of yourself. ***
