Atkins rotary Supercharger

i am seriously thinking about Atkins rotary new super charger, or maybe Petitt's II version.

Kinda hard to turn loose of that 7G's.

if Esmeril ever shows a complete dyno I'll probably be hooked. I had considered a supercharger for a while but I've been pretty set on turbo now for some time.
When I realized it was torque I was after that pretty much ruled the SCs out.

I'll be doing the install myself, tuning I'm not sure on yet. I know a few locals that could probably help me out and I've looked up the local dynos.. but might end up on a road trip if I can't get it tuned somewhat properly myself. I'll be starting with a conservative tune.

I'm also really waiting on cobb to see what they come out with.

thats what my issue would be, tuning...if you find someone local to tune, i would seriously think about turboing my 8. What kit are you going to use? Greddy?

well the *=)* shoulda been a hint to the sarcasm...but if it was serious, it would hearsay from lots of others who say they are junk. Thats they don't rev out enough boost, to small of turbos, badly designed kits that mess up their cars. And also bad experience with greddy kits on rx7s.

The only real problem with the greddys post-fixes is supposedly the turbo that can't keep up. apparently a turbo upgrade really fixes that kit up fine.

I'm planning on going with esmeril racing's kit probably.

well if you want 300 hp now, either go with mazsport, or esmeril. both IMO are the best out there for the 8

a + for mazsport, cause their type 2 kit has a air to water intercooler, which allows a LOT shorter piping for instantaneous turbo response

No doubt the mazsport, and esmeril kit will give you more power. However, I find it irritating to say a turbo kit sucks rather than stating facts. From my own experience, I believe the Greddy Turbo Kit is great for what it is. It's a small turbo, but it characterizes the kit at it's own advantage and disadvantages. As far as the sarcasm, I see it now. I've been shielded from humor these past few days due to finals -_- Forgive me on that

right, every kit has postives and negatives as scott from mazsport told me. the greddy has almost NO lag, but above 7k rpms, it cant supply enough air to the engine. but a couple fixes there, and you have a GREAT turbo kit. A bad thing about the Mazsport turbo kits, is that they are expensive, but hear this. there is 700 dollars worth of material in the exhaust manifold ALONE!!! They use the best parts that are out there, and you needn't buy anything else. A bad thing about the esmeril turbo kit, is that it is also expensive, BUT it can supply HUGE WHP!!

It's you and me both. I've heard of some porting done to the RX8, but I have never heard of any advantages or affects of doing so.

RG in your neck of the woods did CRH's port job. He was exploring the limits of what could and could not be done.

The results were nice, and the initial anecdotal evidence suggests that things have improved...however so far there has been no dynos or hard data to say for certain as of yet...

CRH was breaking-in the engine and may be doing a dyno very soon...

Yea, I remember talking to RG about that, but I believe he was finished with the porting at the time. The way I heard things, it sounded like the Renesis had a lot more potential than most people let on. Definitely a dyno of before and after would be a great determination of advantages to porting the Renesis.

I think in the absence of FI everything else will provide minimal gains, including porting.

Agreed...so far from my opinion...any gains appear to be smoothness and possibly reliability...CRH reported that it felt better/faster on the buttdyno...but thats about as far as I would speculate until a dyno is produced...

Porting isn't cheap either. It's also permanent, where as you can always unbolt a turbo set up.

It's NOT the same thing in this case. The fundamental principle is the same, however its not as easy in a rotary. RG for example hit water on the exhaust ports. Also a port job covers the oil passages and other flow areas. So far RG has been the only person to ever do it that I know of and CRH is the only member to currently be running the housing.

Your best bet for decent power is FI...and contrary to popular belief, its reliable and proven. The renny does not puke out its seals as easily.
