Thought you might be interested in the latest dyno run --
11 pounds of boost, conservative (meaning safe) map.

wow thats awesome,

what turbocharger are u running?

also which ecu?

 

Very basic Turbonetics T4/60-1
Computer is a Haltech P-1000

 

wow that looks like brute force that is a mean set-up!
435whp, 309ft-lbs/tq 11lbs of boost! very impressive.
I need get one of these!

 

Is that an engine dyno or a chassis dyno?

 

No low end yet it peaks at 7500?

 

once tuned more and setup properly (as in to optimize performance and take advantage of the engines potential), this thing will be a monster...

 

Brilliant.

 

The dyno was done on a dyna pack if that means anything!?

 

Is this an extra oil feed on the front cover?

 

Looks like it is.

 

Is it going to be a dry sump setup? That's all I can figure.

 

Doubtful, I saw an oil pan in the other pic.

It might be for an oil cooler line ?... I dunno.

 

the blue AN fitting on the front cover is for the turbo oil drain.

 

Thats an excellent place to put it....

 

I have the same exact thing done inside my 13B-REW the jackets around and near the spark plugs are finned to create more surface area and create a tumble as the coolant crosses through.

There is this really neat Appalachian Hillbilly that lives in Port St. Lucie Florida, his shop is called JR Fabrications (formally Just Racing Fabrications) and he did some amazing work on my engine.




I also never saw apex seals installed while the rotor is in the housing. I have seen neat plastic holding devices that let you slide the rotor down. Or, the low tech rubber band method.



On my REW I found big torque gains when we opened up the throttle body and intake runners, as well as an aggressive street port. The intake runners and TB were opened an easy 20%. The low end grunt is seat of the pants noticeable.

 

I didn't know James Cameron was into rotory engines!

 

have they improved seals in this engine? i know renesis dont last long boosted... would it be better to swap for a rew instead of doing that mod?

 

Only just noticed this . Awesome result . Any more updates since the dyno ?

 

No updates that I know of thus far but here is the link:
Rotary Radness, Mazdatrix's 13B REW/MSP Hybrid!

 

Are those MSP rotors or did they use lower compression out of a diff year? Just curious because i know they Apex seals on the rene are different than standard 13b Apex seals. I have the irons and really contemplating doing a similar build.

 

Renny rotors can be machined to take different seals

Brettus had his rotors machined to take taller 3mm apex seals for example

 

right, but the compression of the MSP is higher. not ideal for boost application. i suppose i should look up clearances and compare my question was more of if another rotor was used would there be tolerance issues with the ports and dropping a seal.

 

High compression is not an issue in boosted applications if you know how to tune. Less margin for mistakes, that's pretty much it.

 

yeah but playing pop goes the weasel with a freshly built motor isn't exactly fun, atleast not on my dollar.
