The Autoexe brace will add 15 lbs. Based on the power upgades he has planed I don't think that's too much.

 

Are you gonna change the flywheel etc as well?

PS I see i got the "blue" idea from the mintblue fittings.....

PPS the Carbon creations link seems a bit weird..its just more links there to random stuff.

 

You are always in good hands with Ray @ PF supercars!

Good luck!

 

well the size of the gauges are pretty small. I should be able to have a 6 pod gauge holder made for where the nav system sits. I think we're using a 9.5 pound fly wheel, with an Exedy carbon on carbon clutch. Won't ever have to worry about a slipping clutch. Hopefully I'll get something in my email about parts Ray orders. Other then that I won't have much to post until further progress is made.

I have a friend running 1000rwhp on the factory rx-7 excentric shafts. I don't think he has twisted any, but it is only for a few seonds down the strip. 600hp should be ok on the shaft.

If i had that much money i would have bought a viper srt-10 and make it a tri-turbo 1600-2000 hp MMMMMOOOOOONNNNNNNSSSSSTTTTEEEERRRRRRRRR :p

 

This all sounds really interesting, but I think you need to re-evaluate your goals. 600 at the wheels is impossible right now, to get there you're talking about thousands of hours of R&D, numerous blown motors and experimentation with rotors and porting work, lots of trial and error with different turbo setups, and broken things that you can't even yet imagine. And in the end, the ONLY way you'll get 600 wheel hp with any 2 rotor is massive porting and a barely streetable turbo.

But since you seem serious, I'll give you some real advice. Dump the cheapo engine management solutions, get a Motec ... nothing else. EGT gauge is worthless, as are some of the other gauges you got - like that big tach. But what gauge you do need is the Innovate LC-1, maybe even a pair for measuring AFR's off each rotor, and get the LM-1 logging box.

Another piece of advice, buy a spare Renesis and start thinking about port work. Contact some other TOP rotary guys, like Carlos Lopez from CLR Racing and Rick Engman down at Mazmart. Those guys are the elite, which is exactly what you'll need to pull this off. A closer guy who has some Renesis experience and could provide some input is Ito at Mothers Performance in North Jersey.

For the turbo setup, you do realize it's all going to have to be custom fabricated. My first guess of 'the best' turbo would be a GT42R, go for all the ball bearing options and talk with Garret tech before ordering to get some advice.

Transmission, fitting up a FD casing is a good idea ... but the stock FD internals can't handle that kind of power either. For another $2500 or so you can get the Guru internals that are MUCH stronger and drop right into the stock tranny casing. I'd highly reccomend that, and a dual disc clutch. Also start looking into having some stronger chromoly axles made, and some strong links for the rear suspension.

You're going to need a full cage, big *** brakes, suspension, and countless other things. I'd say before you spend another dime, sit down with Ray and make a FULL list, spend some time and try to think of everything you need. Get a gameplan made up first, this is going to be a huge undertaking.

Don't jump into this too fast, or you'll end up wasting a lot of money buying the wrong things .. or things you don't need. Just be smart about it, and seek advice from many people.

 

Okay, so I have an update from Ray. I received an email from him today, they mached up the RX7 transmission today. It bolted right up, but the shifter sits back 3" more then the stock RX8 tranny. So we have 1 hurdle we have to clear now and I was already expecting this of course, especially with the complexity of what we are trying to accomplish. Here's a few pics to feast your eyes on.

Great pics thanks for the update!

 

just for the record, autoexe states that they weigh 11kg which is about 24lbs

 

Just for the record you remove 7 lbs of OEM parts when you install it. i should know I have the AutoExe brace :D +- 2 lbs for using a bathroom scale

https://www.rx8club.com/series-i-do-yourself-forum-73/diy-autoexe-member-brace-61120/

 

oh ****, my bad... you win my friend
but still the MS is about half that weight

 

I would have to agree with Ryan on the 600hp, although I would love to be wrong on this. I would shoot for about 400whp first, which I think is doable, then see if you can tweak it up higher. 400whp with a good power curve will be so scary fast you can go hunt nearly an exotic you want. I'm a big fan of the average power wins races theory, so 400whp could techinically be faster than 600 is its all at the top end.

I would also focus on weight reduction if possible, as you are going to be adding weight to the car in the form of your body kit and turbo's. You can save some decent weight, since money is no object ti appears, with lighter tires, wheels, Ti exhaust and a midpipe, which should offset the body kit. and braces.

finally, as the 3rd gen people found out, cooling is everthing. BIG Radiator, BIG Intercooler and BIGGER oil coolers are a must. There is tons of room in there if you remove the airbox and battery, use it. get some custom ducting going with the front air dam.

 

The transmission bolting right up is really cool thing. this will be a neat option for the higher power 8s. Im curious how this car, with what ever horsepower, will fair against a greddy 350z

 

I don't see why 600 whp would be all that difficult to reach. He's my theory behind this. RX7's I've seen them push 650 to 700 whp. Take Dee Karionis (Reactive Racing) for instance (I know I butchered his name). But he has a fully built 13b, and a fully built car pushing 7.90's in the 1/4 mile. Now the Renesis motor is the same 13b that was in the RX7's with the exception of being a better designed motor, in my OPINION. But seriously with what's planned, I think if we don't reach our goal, we'll get DAMN close. But I DO understand all the concerns, and I DO appreciate all the advice and support.

I guess I should also share with you that I received a notification today in my email that I have received several sponsorships from various companies.

So it looks like my project is catching the attention of a few companies already. This is very exciting for me, I had a big smile on my face lol. Anyways it looks like this could be a my one shot, so I'm not going to miss this oppertunity. I hope to continue to gain your support, and I promise to continue to keep all of you (The RX8) Community informed of any findings, wether it's positive, negative, or just plain shooting the breeze with all of you. I do consider this forum one big family, with many different views, and opinions, but hey that's makes us who we are. So I'll be seeing you guys around, and I'll try to post any new information when I get home from PFSupercars on Thursday. Oh and could someone please sticky this? Thanks again guys

If you keep it updated well, I doubt this thread would even need a sticky. More power to you. I'll be keeping track of this thing. :D

 

is there a way to calculate how much cfm a turbo would have to flow to supply enouph air for the theoretical 700+ crank hp? we know that the gt35r is already capable of supplying enouph air to support 400whp which is rouphly about 475 cank hp.

denward

 

here's easy way to think about it.
every pound of air shoved into engine makes 10hp.
so if the turbo can flow 40pounds of air/min, then the engine can make 400 hp to the crank.
let's say our 8 makes 240hp to the crank which does not -.-, anyway, then it requires
24 pounds of air/min to flow into the engine, if we want our engine to be 400hp engine, then we will need a turbo that can flow approximately 40 pounds of air/min.
hope that makes sense.

 

Okay, I just got back from PFSupercars. I have a little bit of an update. He's ordered new parts for the motor, he's ordered an EMS (not going to reveal which one it is at this time to protect Rays work, Sorry folks). Also he's has several ideas for the motor configuration (Again not going to reveal at this time to protect his work) Besides I want to keep you guys in suspense for a little while. I do however PROMISE, that once the car is up and running, has been on the dyno, and we reach our expected goal, I will reveal the ins and outs of the project. OR just maybe I'll leave it to you guys to figure it out :D J/K. I promise once the project is finish I'll let you all know.

Also I have almost all of my parts ordered, the list is getting very long and expensive. Again like I said, not am I only doing this for myself, but for the RX8 community as well. So here is I'd say a 90% complete list of what's been ordered, there are a few other small items that I'll be picking up from here and there.

Right now we are still on the projected budget, like I said probably about 90% of the parts are ordered. Still have small things like the racing seat, 4 point harness, mirrors, and small stuff like that left which should only set me back about another 2,000 dollars. Then the rest of the money will go towards install, motor work, and paint. So keep checking back regularly, and I'll update as often as possible.

 

About your list make sure parts like the AutoExe stuff & other non-USA parts are in stock and in the USA. It took over 4 months for my AutoExe subframe brace to come from Japan. I don't think you want this project slowed down waiting on parts from Japan.

 

Nice list ... a bit ricey but not too bad.

Rotora brakes are crap by the way, made only for looks with no real engineering behind them. If you ever plan on putting your car on a road course, you'll see what I mean.

 

WOW 33K a year that must of been one hell of an invetsment on your parents part. Microsoft maybe?....I make 80K a yeak and still don't have that much disposable income.....what the hell am I doing wrong....Oh ya Married...

 

Hey Boostd 7, what do you think of Grex brakes. Are they good on a road course?

 

a bit ricey? It's far away from being ricey. Ricey would include primered bumpers, a fart can muffler, a fully gutted interior, and duct tape. Also the turbo you recommended the GT42R, what the hell are you trying to turbo with that thing? A FREAKIN TANK!? I saw the GT42R turbo, and it was HUGE, there's no need for a turbo of that size. Rotora brakes are crap? You must be outta your mind. Here's the stats

Rotora Big Brake Kit
6 piston calipers
13 inch rotors
slotted/cross drilled
335 x 32 mm

All I'm saying Ryan, is that I've never had a problem with Rotora before. I'll be getting a set for my FC as well, when the next year rolls around. And can ya guess what's going on my FD? yep, you guess it Rotora's.

Your suggestion for the Guru transmission is a great idea, but 2 things. First the gears in the Guru tranny are straight cut, and will be noisy as hell. Second why spend 2500$ on a dog box unit? When the FD guys build 500, 550, 600 hp RX7's and you don't hear about them using dog boxes. As a matter of fact, most of them get away with a light weight fly wheel, and an good clutch. Or at least the FD owners I know of.

The place I ordered my parts from Bulletproof Automotive drop ships everything from Japan. So it'll take 2 to 3 months to get everything. I've worked with them once before and they are very helpful, and very accurate on how long things will take. I think the first time they were off by 2 days.

I'm not disagreeing with anyone here, just stating my opinion. Anyways I'm out of here to take a nap. I'll talk to every one later, take care all.

C.J.

 

Wow I can't wait to hear more. Did you ever dyno your car after you got your new transmission? I though I read earlier that you were going to, but I don't remember if you ever did or not.
