Looks like your Poppin Collars and Droppin Dollars bud, sounds fun I'm only about 45mins away here in DC, I'll probably stop by the next chance I get, maybe Columbus Day weekend.

600hp does sound a little far fetched, if you do use the GT35R and manage to pump in 25psi without breaking, I’ll guess and say you'll make about 490 peek @the wheels.

I'll be in DC till late December, I haven't spoken to Ryan yet but if it does turn out to make anything more then 400 to the wheels it will be impressive, and im sure that he'll want to have an article in RxTuner about for it, I'll be glad to photograph and of course give you all my personal driving impressions

Are you doing anything special to the rotors when you say custom machining, specifically? (still renesis rotors right?)

 

I thought drivetrain loss wasn't cumulative like that? Can someone explain the effects of drivetrain loss, or point me to a thread that does?

 

Um, you're still not getting it :p

 

Yep PoLak, I'm still talking Renesis motor. I can't really say what's going on with the internals, it's a secret. Of course I already know what that secret it, but I can't let the cat out of the bag yet. Maybe it'll be done in time for Christmas. It can be my Christmas present to myself, lol.

 

Polak,

talk to Ryan if he have interest to come to Puerto Rico, Before the porting we maked 392 HP at 19 psi of boost..........now we're making 374 HP at 14 psi of boost. We have another car with basically the same settings that we're goin to finish on a couple of weeks.
There is also another RX8 from s different shop that is using the greddy kit plus 200 pound of nitrous, I don't know how much HP he is making but looks interesting!

Manuel

 

Ok then long as ur not putting lower compression rotors or something of the sort in, machining the Renesis rotors will be cool, kinda keeps it being a RENESIS not some 13bREW halfing, if you know what I mean.

 

CJ's 8 will be sick and i know he will be taking good care of it cuz i just bought his 7 and he took care of that. im excited to see the finished 8 and the CYM 7 there both gunna be awesome. good luck CJ

 

Okay, so Ray is going to begin to fabricate the turbo system starting Monday. Of course still don't have a turbo choice yet. Also for the people that requested it. Ray is going to dyno the RX8 stock with the FD transmission in it, so once he builds the links for the shifter, he's going to get it back on the Dyno and check out the numbers. So that'll all I have for now, nothing really special, but I wanted to update what I could. Anyways I'll try to update you guys next week.

C.J.

 

Thanks...

 

You think a GT42R is too big? There are more than enough 2nd and 3rd gen rx7 guys running around with GT42R's on to make big numbers, a GT35R will not make 600rwhp, it'll just get choked to hell. I've seen stock port FD's and *some* (though it's harder) FC's peak at just above 400rwhp with the GT35R, with any kind of semi-large or big porting that'll just cause the turbo to get choked even more up top, you need something larger for the HP you want.

Also, "custom rotors," what does that mean? I'm willing to guess that he's gonna end up doing something like putting in 3rd gen rx7 rotors that have been lightened and balanced. Mainly because 9.0:1 rotors are going to be easier to tune with high psi than 10.0:1, and what else could you/he mean by "custom" anyways? Other than lightening the rotors and making the scallop larger for more port timing, what else can be done? Are you saying you're going to lower the compression yourselves with the CNC? Seems kind of expensive and worthless when lower compression rotors are readily available from other rotary cars and can be further customized.

Is this something similar to what he's talking about doing for "custom rotors?"

 

Yeah, I've got a GT42R on my GTUs. There's just about no way you'll get the numbers you want with a 35. Also, as a general note, the second anybody says 'secret' when discussing building a rotary engine, my flag goes up to get the hell away. For some reason I've noticed the Peurto Rican builders do this a LOT, "Oh we've got some secrets from the island that nobody else uses, makes some sick power...", which usually results in a lighter pocketbook and nothing more than the basic stuff people have been doing for years. There's really nothing left to be secretive other than the port design itself from person to person.

 

This is the greatest thread ever. I can only imagine how this will end.
Just a request, can you start a new thread after each milestone. This can easy grow to 50+ pages.

 

Hi Fightman,
can i know what compression you planning to run?? Using RX7 rotor?? sorry for asking if the compression has been mentioned b4 ...
tq

 

I thought running REW rotors in the Renesis wasn't possible due to reformatted side seals and clearancing. As I recall, Amemiya was experimenting with this but nothing really came of it.

 

Yeah finish this thread with your stock dyno + transmisison and start a new one for each major addition! (with a link on the end of last post to the new one)

 

If another thread is started, lock it so that only you can update it; it will be purely about the quest and the car. I'd be for making it a sticky. This thread can stay alive for comments and discussion but the new one exists purely for the information while not getting inflated by every post ***** and naysayer on the boards. Easy to link over to particulars from here. That's my thought on it.

 

Yeah I totally agree with you Ranger. So yeah once I get the new Dyno numbers up I'll start a new thread, with just updates, positive, negative what ever it may be. Then we'll keep this thread alive for questions and comments. I still don't think my numbers are unattainable. Ray is probably one of the top 3 Rotary Mechanics on the East Coast, that I know of. Another is Acosta Motorsports, but they were up in Jersey. Again we'll have to see what happens, we may get there, we may not, but at least when I get my car back it'll be a hell of a lot better then it is now, lol.

Oh and a small update on the brake kit. I'm doing stoptech big brakes on all 4 corners. Thanks for the advice Ryan.

C.J.

 

If you stick with a 35R they won't be, unless you're talking BHP? If that's the case, 25psi on the 35R would probably do right around there

 

Nope he's definitely not.

First post.

I don't see why people are having issues with others making comments (positive or negative). As you can see he already changed his mind on the brakes due to Ryan's advice, so if someone can step in that has seen what the 35R can do, or knows what the 35R/42R can do from experience (SonicRaT), why not comment? Maybe it'll get him researching or questioning those portions of the project more because of the comments, to make sure he was accurate originally. Then maybe he'll find that some of these people may have some justification with what they say, thus he changes his plans to compensate (possibly). What's wrong with that? Better to try and help someone from spending unneeded money or possibly going in the direction of something that MAY not reach the goals he wants than to not say anything and have him possibly be disappointed, or not AS happy, when the project is complete. Not saying that the 35R wont make some power and be a good turbo, but 600rwhp... eh, probably not.

 

Hey Eightman, I just wanna let u know that I think ur idea is awesome and I really appreciate u being so proactive. I support this adventure 110% and i hope u have great success. I recently ordered the greddy turbo and thought I took a big step man, but ur definitely taking a big step for mankind .

 

I'm not sure who said that we were going to use a GT35R turbo, but I can assure you that is not the turbo that will going on this car. The GT42R is an awesome turbo but we have a limited amount of space to work with, and you don't need a turbo that big to make 600rwhp on a 2 rotor. I also couldn't agree with you more about people trying to be secretive, it's usually BS. There isn't any secrets with what happening to C.J.'s car, whether he shares his mods is up to him. Imagine that sales pitch...It's going be $xx,xxx dollars but I can't tell you what were going to do, it's a secret!

 

PTP's turbo kit (GT35R) without their fuel management system put out 350 hp and almost 300 torgue at the wheels. They expect 400 with the fuel system.

 

Your point? I was never talking about 300-400rwhp... Yes that is attainable with a GT35R, but the thread starter was talking about 600RWHP, totally different story.

 

Exactly, Ryan put some advice out there, I did a little more research, and changed my mind. But as far as the engine decisions go, that's all on Rays shoulders. He's the Rotary guy here, I'm just along for the ride. Such as the Vertical Doors, I kept looking at other RX8's with vertical doors and decide to change my mind on not getting them. I'm sure everyone understands that building a car of this caliber is not an overnight decision. It takes months of planning, which I've been doing since I've bought the car in Feb. 04. My planning has involved research on the motor, buying service manuals to understand further how things work, deciding on parts I wanted to use, paint color, rim size, color, even planning on down to the E-brake handle as ludicris as that sounds. So there may be some decisions that get changed around. Such as if I would have waited 2 more weeks before ordering my body kit, I'd probably be buying the R-Magic Widebody that just came out for the 8, instead of the Mint Blue, as much as I love that kit.

So in short, nothing is set in stone as of yet. I've kept saying we haven't made a turbo selection yet. We are however, going to start fabricating the turbo kit Monday. Now we do have the ECU picked out, and I believe it's the best decision for this application, although we're going to hold off revealing which choice we went with. All will be revealed at the end of the build, cause what fun would it be if you knew the end results before we got to the final scene? :D

Anyways, I'll be heading up to PFSupercars again next Thursday, October 6th. If anyone wants to come along, we'll be meeting at Mcdonald's/Checker (they are right next to each other) on Ritchie Highway in Glen Burnie. Meet time will be 1:30 pm with roll out time at 2:00pm SHARP. It's about an 1 hour drive one way. If you'd like to come along and check out the shop, you're more then welcome to come.

C.J.

 

I still can't get over how you have a 3rd gen as your daily driver :D
