ernie, so what rwhp level did you specifically see failure at in your car with the ra seals, I was just looking at their website agian and it looks like some pretty insane drag cars are running them with what I would imagine would be well over 700hp. Just thought I would pick your brain a little, it would not be a big deal to throw some new seals in there after this summer if these are garbage.

Par for my course. Im sorry Ive been being an ass lately.

Things I like: youre going crazy and doing it your way.
Things I dont like: nitrous, wheels, street racing.

have fun, go nuts

They will warp before they break. That is a good thing I suppose. They warp fast though.

Just finished on the dyno....roughly 620 at 24psi. Injectors were basically maxed out so this will do for now. There was room for a bit more, but we kelp it fairly safe.

https://www.rx7club.com/single-turbo-rx-7s-23/full-bridge-gt42-dyno-789741/

seems like the 600 the old setup put down still holds true in our set up....this should be a fun dubbed out shopping cart

I think you should enjoy the car for now, next spring why don't you come back down after you add some more fuel upgrades. let's tune it for more boost, That motor and turbo just wants more boost as you can see from the dyno.

Updating this thread a bit...
Plans for the near future include an Excessive lower intake manifold, or perhaps custom, along with a custom upper intake manifold. Another rail of 1600 secondaries will also be added.
Studs and a 2 piece shaft will also be used, perhaps a custom shaft....this is still being looked into, along with some other drive line bits further on down the road. The current power is more than enough for the stock wheels and tires as it is.

In the current state the motor made 620 at 24 psi... if we had leaned it out a bit, it was guessed that 640, maybe 650 could have been done (just speculating based on what we saw while making numerous pulls on the dyno). We played it safe though as the injectors were basically maxed.
With the supporting fuel, new lower and upper intake, and a few more psi, I would think 700 rwhp could be achieved at 27 or so.... Not trying to open a can of worms or anything, but by going off the claims I've seen others document when using custom manifolds, and say 15 rwhp per psi, that would put it right in the ball park of 700. I feel like we've been challenged!
In all seriousness though, it does seem doable, no?

I'm not trying to take any sort of superior attitude over anyone, I simply want to push the limits. I do not believe 600 rwhp has been done with AI on a 13B until now (a few others have just done it now too!), which, is exciting. It would not have been done without the advice and knowledge gained from others. As far as physics goes... it is exactly that which tells me the limit has not been reached. Based off what I know, and what I've seen from others, there's room for much more...700 plus on a two rotor...not a problem. Ernie is proof enough of that, and there are others. 700 plus on pump gas and AI...I'm thinking yes.
And what I meant when I said the wheels were different, was simply that. They're not the stock 5 spokes. Gaudy, yes perhaps.
The lag really isn't too bad.... on the street, anything above 4500 and it gets scary. The low end isn't real responsive, but that was never one of the goals to begin with, so its really no big deal. It makes driving around town quite easy as its so docile.
Thanks on the piping, I'm happy with the way it turned out too:D

Not sure why we should have stuck with supras... they're heavy and we wanted a much lighter platform.
The old setup was basically identical minus the exhaust from the DP back and the intercooler and piping.... so unless something is seriously messed up, one would think the numbers would be fairly similar, which they were.

Nitrous will not be used. There is no need for it.

I do not see the how building a high horsepower car that can be easily driven on the street can be compared to a "shopping cart with dubs." It's unique, fun to drive (perhaps too fun...I wont get into that:D), easy enough to drive, and is not done in poor taste. The wheels...ok, so they're a bit ostentatious. They'll fit in alot better and make more sense once the body is done. Trust me. Or not.....

I don't like you? I wouldn't say that... I don't even know you. Just some of your comments are a bit childish and lack technical support, thats all.

700 + rwhp does not equate to blowing the motor, as Ernie already pointed out.

Next step is getting coilovers under her and prepping for the fiberglass widebody to fit the new shoes.

Where did you get the Veilside Wheels? Arent they discontinued? Im curious because I want to get some Veilside wheels in the future, a different model then yours though.

Real solid looking build, you have going.

So you're running 1000cc primaries and 1680cc secondaries? I understand you're running more injectors on the next setup, I'm just wondering what you did on the 620 whp setup.

I dont know how to explain this to you subtly; but that is a me problem. The fact of the matter is that high horsepower rotaries are failure prone. More to the point: all high horsepower engines are failure prone due to the additional stresses that kind of power entails. And,(everyone cover your ears) rotaries are more failure prone than piston engines.

So here you are with an engine that belongs on a dragstrip(but is not intended to see one), wheels straight out of The Fast & The Furious(that cringe at the first mention of a pothole), A body kit that probably resembles something from JGTC(though I've never seen it), and coilovers that are too stiff to street but too soft to race(which you dont want to do anyways).

So, what it all adds up to is a "street car" with road manners, practicality, and driveability far inferior to that of my 1997 Mercury Grand Marquis(which is not something I would say about most of the single setup Rx7s on this forums; much less, a stock Rx7)

You are essentially building the largest, shiniest, loudest, fastest penis to ever see a four-lane highway. But you seem to be having fun; which is really what it's all about, right?

cheers,
Barban.

Dude, nice! From the pics, it looks like you're doing some quality work. I, for one, really like your Veilside wheels, to each his own... It's your car, you're doing your thing with it, I respect that. New pics?

it's that time of year in Packerland where we sick-os start doing all kinds of crazy mods. while the snow piles up.

just a few thoughts on your project for 09.

you are combining monster hp w monster stick. the poor old fd trans is stuck in the middle. you will be stripping 3rd gear teeth out of your trans lots. it is going to be a major issue for your car no matter how you drive it.

the rear end can hold up o k if it is properly gusseted. axles o k too if you aren't drag racing.

i currently have a T56 on my shop floor and am planning to swap it into my FD. it will need to be spaced back just under 4 inches from the FD bellhousing to clear the starter. Libertys gears will make a longer input shaft. in addition the front plate on the trans case will have to be machined to just outboard of the 11 bolts so as to reduce the outer dimension to 10 inches. a spacer w a 7 inch tube will connect the T56 and the FD bellhousing. with a minimum of GTO syncros the trans will shift at 8250 and you will not break it. you could go T56 or you could just break a whole lot of FD boxes. maybe you might consider partnering up on my project. make one, make two adapters... what's the diff.

i am doing the swap because i want to run 200 in the Texas Standing Mile and need the additional gearing.
ratios for me will be: 2.97, 2.07, 1.43, 1, .8, .62

you really are going to need more trans.

the other issue is your motor above 600 rwhp. while i have not yet made 600, but expect to next year, it seems that anything much over 600 and you start to get e-shaft flex to the point where your rotors are not happy w the irons. many that run in that hp area run 2 piece cranks w center main bearings.

or

you might find it pleasant to just tool around the street w paltry 600 hp.

and then knowing you, you might not.

don't go too crazy this winter.

hc

I actually out of chance found them on Ebay...for a rediculous price too. I'm not sure if you can get them still or not. I want to say I had found a place that stocked them...(this was a few years back though). My best advice is to try Ebay time to time and you may get lucky.

Thanks guys! we may have some new body mock up pics soon...we'll see.

Correct.

First of all, enough with the fast and the furious talk, ha...I already said earlier I'm not too happy with the red rx7:-(
The "Big Stick" supra and the Veilside drag R34 were the inspiration for those long before that stupid movie... Whatever, I love em:-D

The Texas Mile is the main encouragement for the power. Granted, its more failure prone at those levels. And practicality was never the goal with this car, thats why we all have our daily drivers, right?

Couldn't agree more with your last sentence.

How's it going Howard?
The trans and diff will be braced up. The axles will most likely be left alone for now...I doubt it will see too many hard launches.

I like the idea of the T56, that may be something we'll look into.
We have all the gearing we need with the auto diff and taller tires, but like you say, who knows how long it'll hold up making hard pulls.

Not too much else will be done power wise until the shaft is addressed. Either 2 piece or something else...along with studs.

I'll be shooting you a pm...

Just got some coilovers for the ol' birthday, so we got the car down to where it needs to be.
Trimmed the rear fenders a bit to allow for the talller tires. Next step is the body...

So the build is for the Texas Mile? There is a point to the madness then :icon_tup:
Wheels don't look that bad. At least once you put the wide fender on.
Good Luck, Keep us updated please :)

A few more...

I like it... :icon_tup:

Who says there needs to be reason to the madness? Nothing is permanent.

Hey Gordon, you're right... if its one thing I've seen with those involved in the texas mile is the lack of attention given to aero... even the new Supra that did 252 mph (wow) was basically bone stock, nothing done in the name of aero. (I suppose when you're putting down 1500+ to the wheels you can say who cares...)
The next big step for this car will be the body, and everything will be done in the consideration of being as slippery as possible, as well as keeping the car planted at speed.
The front of the car will be elongated approx. 8" at the bottom, coming to more of a point. The rear bumper will be brought downward to match the reast of the body to further increase the distance the air must travel under the car. A flat tray with two diffuser channels will take care of the bottom, and we are still playing with where the new exhaust will be routed. Wheel wells vented, mirrors replaced, possibly smoothing panel seams...It'll look pretty radical. Tastefully radical however. No akward lines, no buldging flares that dont follow body lines... smooth.
I remember there being a thread sometime ago where someone recorded the time it took to go from 60-160 or so with the headlights up, the headlights down... the wheel well plastic in, and with it removed, and I want to say there was over a second to be gained from just simple mods like these. Add it up and there's a few seconds to possibly be gained... a few seconds within a 20-24 second window is huge.

Thanks Zen:-) Thats a good way of looking at it.

Update:
New suspension and brake lines are in. Carbon seats are in. Cage installed. Engine Bay cleaned, fuse boxes/etc. relocated. Fenders trimmed. Turbo machined, blanket on.
The new body (longer/wider/aero friendly) is being finished up along with undertray and diffuser, should be complete within the next 1-2 months.
More pics and video to come soon.

Impressive build up !!!

But im wondering and asking myself WHY would someone go from 600 horses up to more horses??? HP-Junkie? Was there a faster car that beat you???

WHEN my FD runs fine, my goals are about 300-400 hp :-)

The reason for more power would be the Texas Mile... that, and to see just how far we can take it.
First drive of the year. 150 without doors is an uneasy feeling. New body panels are almost finished up... fiberglass is a PITA.
