was it a 3rd gen.? b/c if so, that's my boy rob, he's supposed to be pushing about 800hp, or that's what he said he dynoed

I wouldnt believe to much else Rob tells you. 800 is achievable on a 13B but he did not make 800. If he did, the car would not be driving on the street even if he was "only" imbelishing his numbers by 150hp.

Oh good god...... I know who you are talking about. He went to ATC... and hes the biggest liar about his car I have ever meet. Sorry but you "boy" is an idiot

pwnd.

No no no, I was just reacting to the 800hp reply. I don't think I've ever heard of anybody dynoing that high, maybe 500-600 horse.

i was told that he dropped a $10,000 race motor in, with the twin turbo setup, the Hp went up to about 720 or something, then dropped, so he's supposively switching to a single huge turbo to hold the HP to redline, i can't really say much more b/c i barely know anything about rotory engines

i guess it was a 3rd gen, my guess would have to be in the area of a 1994-95 maybe, it looked real clean, no front mount though, so i am guessing it was probly pretty stock

usually rx7's run v-mount's...the front mount blocks to much air to the rad...my friends got one on his

That's true, but If you run a front mount with a v-mounted radiator it works well too. I see consistent 85-90?C coolant temps in my car. With the biggest front mount apexi makes.

720whp on twin turbo's?? thats crazy...I always thought to make that power you were already on huge t-88 single turbo upgrade prolly on a 3 rotor motor already...anyways sounds like a beast!!

[KGParts]

So much mis-info/BS in this thread I personally think it should be locked. I have to refrain from even saying anything else....

[D Money]

lol..if you have info on rx7's please tell us...I really dont know much about them..just two friends with them...just those cars are so complicated and when people talk about them its like a different language!

[US_R33]

you def. don't need a 3 rotor in order to make that kind of power out of a rotary lol......and most RX-7s don't run V-mounts.....not sure where that one came from

[nopistons94]

Alright guys, Im posting in this thread to just end the rumors around this whole thing. I'm going to reply to each comment that I've noticed to be wrong or something I have a opnion on. Don't get mad at me for whatever I say!

Honestly, 10,000 dollars for a "race motor" its a pretty hefty price tag for a 13b-REW. Even a heavily streetported or hell even a bridgeported motor won't cost you 10g's. Do you mean 10k with the turbo setup and the motor?

Running a aftermarket tt setup on a RX-7 is basically retarted. I know it's cool to be different and try new things, but a big single is the way to go. VERY few FD owners will attempt to get a TT setup, and very few tuners like to mess with that. Your right on the fact that a big single won't run out of breath as fast as a tt setup though.

Please tell your friend to post in this thread with his DYNO sheet, and was this on a mustang dyno? I'm also intrested in hearing what his setup is.

What injectors, UIM, LIM, IC, Fuel pressure reg, fuel pump, lines and fittings(-6 most likely), turbos (A/F trim type size ect ect), what manifold he has for this TT setup (has to be custom there isn't a TT setup around like this off the shelf), also the specs on the motor itself. What size porting on the exhaust and intake ports, what type of apex seals, what type of O-rings, ect ect. So tell your friend to come to this thread and post up, especially his dyno sheet.

The highest HP recorded on a 13b=REW block was in the 800 range, im sure all you guys have seen the video of the red RX7 that made 800ps ? Well thats about ~730 hp for you non metric guys.

Honestly, I don't think you know exactly what your talking about on this post bro. A eccentric shaft (basically a rotary's crank) for a custom 4 rotor (26b setup) in the manner in which your speaking in is over 20 thousand dollars. There IS a way to get a eccentric shaft built for about 5-8k and its over in the NZ, austraila shops. NO ONE IN AMERICA on a street car has a 26b. There is a 26b BMW drag car and a few others but thats all. Mazda never produced a 4 rotor setup for any street car, ever. The only production 4 rotor motors that came from mazda are for the Le Mans car(which got banned from the circuit). These motors are worth in excess of 100,000 dollars and arn't even able to purschase.

making that high of horsepower on a rotary isn't impossible, just not very reliable......but there's no way in hell i would believe even my best friend if he "told me" that he dynoed at those numbers w/o personally seeing the SAE corrected dyno chart myself

Your very right on this post brotha. IF IF this guy is making 800 hp, first of all his drivetrain can be NO where near stock, meaning he HAS to have a different rear, torsen arms and all that good stuff. And your right, a 4 rotor setup would be WELL over 15,000 JUST FOR THE MOTOR. After you buy the motor, you need EVERYTHING else meaing an ECU that can run it(no one in the world makes a 26b ECU), the fuel for it, a subframe and completly custom motor mouting systems. This would be a 60-80k dollar "swap". good post

You have your rad V mounted with a FMIC setup? Please show me pictures. Basically every FMIC setup requires the rad to be Straight up mouting. Trust me, take your FD to the track, you won't be seeing 85-90c coolant temps on your commander anymore heh

Depending on what application you use your car, the type of IC can be a factor. when pushing the car hard for a total of under 12 seconds or driving it on a street a FIMC is not bad, and IMO a better choice than a SMIC. Road race on the other hand, cooling the engine that is being pushed is where you would shy away from one.
Having a radiator mounted on an "angle" doesnt equate to have a "V- mounted radiator" either. This is due to having a radiator large enough to do the job and not enough room under the hood to mount it.
I know a little about rotary engines as I manufacture many parts for them and have these parts on cars running as low as 7 et's and high MPH traps. ( http://www.kgparts.com/Times.htm )

you da man . For dragging, a FMIC on a FD is perfectly safe, however for auto X or road racing, overheating WILL happen. My car is getting setup for road racing in VIR, if you guys ever heard of that, going down in summer, hopefully it will be sick. My FD is not a drag car and never will be.

If these videos are in Japan, keep in mind they use a metric system for measuring power, so you MIGHT see a 1000 ps rx7 but that is not 1000 hp.





Alright guys, sorry for the long ass thread, hope I could clear some things up for you all. If anyone has anymore questions or thoughts, feel free to chime in and I can usually answer most . I'm pretty sure I didn't forget anything I wanted to say, but I prob did somewhere, and plus enough is enough right LOL. later guys

It is not sitting flat like most v mount intercoolers. More at like a 75?angle. Gets alot of airflow though. I will take some good fliks tommorrow
