but go ahead and prove to yourself what a number of us already know to be true

We could have tried if you had kept that last short block Mark!

The only downside is the custom exhaust side engine mount required... no biggie

Royal Navy's Rotorhead
Not sure on the power figure but it's running a mapped stock ecu and it is a lot quieter than a peripheral exhaust.

Also consider that the engine is not limited during the intake stroke, it's the exhaust ports shape that is crap from a performance point of view.
By keeping the OE intake manifold and using a different port location & timing you reach a decent compromise that the stock PCM is fully capable to withstand

The reason behind going peripheral exhaust\side intake was dictated by the rpm versatility of the OE intake manifold and the benefits of a MAF based setup when a broad powerband is required.

Well i don't think it's a matter of purpose if you want "power" without going full PP (which is a very well known and explored territory by itself).
What limits a renesis is not the intake, it's the exhaust (more its "route" than its location) so going peripheral exhaust without sacrificing the good (yet not perfect) intake we have is the most logical solution. Of course you have to raise the rev limiter to 9700\9800rpm to take full advantage of such configuration.
The only problem with a peripheral exhaust, engine mount aside, is its shape and duration. You do have to port them in order to gain a tangible benefit from the mod. Welding the oe exhaust ports may also be a pain in the *** if the shop doesn't have the right tools and skills.
The last problem is that the engine is no longer technically a renesis but who cares!

Release the twins.
I think in all fairness, is this not an N/a whp "arms-race"??
those who Bridgeport can't turbo, b/c honestly you don't need a bridge port, if you can just go FI.
i think the future developement and mods to the rotary could lead to higher and higher NA hp levels, what is the known max for ANY 1300cc wankle, that would be a full PP, and it's probably around 330-350whp?
I hope you've all seen define's 230rwhp 13b-RE block. Take the ports from that, and add the area's of BDC's latest 241 whp block's ports, and see what would develope. then add PP ports controlled on both ends intake and exhaust(i've said too much here). This is what I "plan" to do. sure it won't be a renesis or technically any exsistant block, it will be ... a HYSELL block. thats my last name.
