A) a 13 is not uncatchable

B) The 8 still needs FI that way Neons and WRXs can't pick on you

C) No way in hell 100rwhp will take 2 seconds off a 1/4. Gotta remember that's peak power and you don't know how fat the curve got. I say a 13.3 is what you should expect and be happy with.

a 13.3? that is cookin, and good enough for me, then you can sand a chance against, stis, evo8, mustangs, firebirds, gtos, camaros....

and i also believe a 13.3 rotary would beat a c5 corvette (13.0) on the highway.



in a closed coarse of coarse :/

i like that on the highway (on a closed coarse of coarse).
i would love to take care of a cupple local cars my self. i have the only 8 for some distance ,helps when u live in the middle of nowhere,but i would love to swing by this guys shop whin im in FL in 2 months to check it out and think about getting one my selfeven though id prefer a SC.

Drewstein

Doubt it. The C5 has better areo and usually traps 110+. Plus it's modded to stock you're talking about. A simple intake/exhaust combo on the C5 would be enough to ensure victory. Plus you can buy them for 20k now (used of course).

But I would be more than happy to be a 13.3 in the 8 none the less.

But..the corvette is an ugly power beast...IMO..american muscle is so very ugly and that's all it is..power...

WTF no turbo

Can anyone confirm he blew it up?I heard through the grapevine 13psi and it went boom.I hope im wrong.

hasg

I wouldn't doubt it

13psi in a 10:1 rotary? I hope he was running 105 octane or sub-zero intake temps.

2mm seals - crack
thin wall lightweigt rotors - crack
It's a lot to ask of the stock RENESIS

army_rx8

Could you switch out the high compression rotors in teh 13b-msp for low compresion ones out of a 13b-rew? I know you may have to change out the stationary gears and what not. But i can' tfind anywhere saying that this wouldn't work... just not too many people have cracked open the engine, to mess with the internals. If anyone has a clue abou tthe internal swithability of 13b parts please give me a pm. thanks a lot guys.

thats a matter of opinion, the corvette is very attractive imo, and it handles great! stops great! and goes fast.
trans am has an awesome look to it, (ws6) the ss camaro is good looking also....

I haven't even finished reading the review by Seiji Tashima, one of the leading RE designers at Mazda, and I can already tell you it won't work. Why? The seals alone are entirely different for various reasons. One is becuase of the change to a side port exhaust instead of peripheral port exhaust. The Renesis isn't looking very interchangable with any other RE parts... lots of changes were made that seem to make it incompatible.

Japan8

Actually I am wondering about the viablility of FI on the Renesis as well however...

what's wrong with 2mm seals? The 13B-REW has 2mm seals. Although the 13B-REW's apex seals are 3 piece instead of 2 piece like on the Renesis.

Instead of thinking about 13psi in 10:1 rotary... what is the effective compression ratio in a 13B-REW when you're pushing 20+ psi? let's compare that figure to the effective compression ratio we get on the Renesis at 13psi.

1stRX8

How reliable is an FD at 20psi? On pump gas with a good and properly tuned management scheme.

I have never built one, but I would guess that it would be on the edge any time you go WOT with it. Is it not fair to say that stuffing air into the engine at 20psi is for someone that is prepared to replace the engine at any moment?

I am talking about street application. I know that race applications go way higher than 20psi, but that is a different topic all together.

Wow, this all sounds pretty awesome. One of my friends on my ship is planning on getting a new 8 when we get back from deployment. I'm sure he'll be ecstatic to hear about this development. He might just be able to keep up with me then. :D

Any new updates?

Guys,
I hope not but is this just another collapsed turbo story? I mean, I believe Genom had the ride but it's been a month now and no info. If someone is succesfully running a turbo it seems the doors would have been beat down to get to them. I wonder if it blew?

Genom

Welp, I've tried calling the guy a few times off and on with no results. I might be able to stop by the shop this saturday, but I'm guessing the 12PSI testing might have had some bad side effects (only reason I could think of the guy not wanting to sell a pile of these).

punishr

Keep trying Genom. Thanks for all of the updates..........
