600 rwhp & T-66
 

Okay, I don't have an FD yet, but I do havea 2001 MR2 Spyder, so getting one shouldn't be a problem. The problem is that I want 600 rwhp. Some are saying it's not possible for a 600 rwhp streetable car. I don't care if it's streetable legally (we all know most RX-7s aren't anymore), just driveable enough for the street. Anyone know a way to do it?

Also, as another question, what are the limits of a T-66 turbo? boost and HP wise? Thanks.

There are only two RX-7's in the world with that kind of power....Ari @ RX-7.com and Cam @ Pettit....

Getting your car to that level will be extremely difficult not to mention extremely expensive.

You're going to need ALOT of porting, and a big turbo, such as a T-78, T-88, T-76. A T-66 probably won't fit the bill. A custom 4" exhaust may also help.:)

Didn't pluto do 585 rwhp? He has a T-66 with .96 turbine housing.

Only 2?
 

Well that's a shame. I live in northenr VA, about 25 min (if that)from PFS. I'd imagine they could do it if I have the cash. I don't right now since apparently this is even tougher than thought, but I wouldn't mind 600 crank hp either. If a T-66 can put out 500 rwhp, well-tuned, then I would be happy. Not trying to run that power all day long. Just in case I see a modena, lambo, or something worthy of turning up to that level of boost to beat them even worse. :D

Who's pluto? What kind of boost was he running. I suppose if the tuner is REALLY good it could be done. I guess my view could be clouded ever since I saw a guy with a T-70 run a 14.8 second 1/4 mile.:)

If I were you I would stay around 450 - 500 hp cause you will have a shitload of problems with the driveline. 600 hp s really not necessary on a street car. 400 hp will kick your ass around.

Way to go Greg! I know someone out here with close to 400 RWHP, and he breaks the wheels loose in 3rd at 60. John Carmack's TT Testarossa breaks the wheels loose at 140, but he has 1600 HP.:eek:

1600!!
 

Jesus, sorry guys, but screw an FD I want that. No just kidding; okay maybe not. ANy videos of that thing or pics of the engine bay. I love TRs. Rode in one from my uncle's dealership (used to work at a ferrari delaership, then owned his own exotic dealership in FL, now owns an 11,000 sq ft restoration shop and does all of Champion porsches aero & wheel work) and thought it was about the greatest car ever made.

Okay back on topic. Yes, Who is Pluto? I was hoping for the breaking the wheels loose at 100 that was stated in another post. That'd be fun. So what are the limits of a T-66, and what's a good rwhp figure for a well configured, tuned, and safe T-66? I wouldn't really want to run more than 25 psi ever, and prefer to never go above 22. My 3 daily settings, depending on hp output would be 10, 15, 20 or 18. 18 or 20 PSI would give me over 400 rwhp right? Thanks, you guys are great.

For a moron like me explain this breaking the wheels loose?
sorry im a dumb ass explain please

Pluto = Steve Kan .... maybe you've heard of him?

Good tuner . . . well that could be Steve.

Making over 400RWHP is not that hard in an FD.. I think you would have trouble driving an FD with that much power.. If you pulled the exhaust & twinturbo setup you would probably loose a bit of weight.. If it is a base or r1 then the car is only going to weight ~2700lbs.. with 400RWHP that is a damn fast car.. There are a couple people running in the 500RWHP on this board.. I do not think it is that tough.. you just have to know what you are doing.. With a nice water injection system it shouldn't be that hard...

a T-66 is a great street/strip turbo, its slightly smaller than the Mitsubishi T-78...a nicely ported motor and a T-66 is a great combo

I want to be able to beat 700+hp Supras on the highway. What type of turbo and what kind of port job would I need? 20B is not an option -- I don't have that much money.

Breaking the wheels loose is getting the wheels spinning without dropping the clutch. Like in the post above, if you were to floor it in 3rd gear at a low rpm, the power builds and at whatever rpm 60mph occurs at the power overcomes the grip of the rear tires and they start spinning.

Re: 1600!!
 

I read the article about his car in Street Power about 4-5 years ago. He's the guy who invented the computer game Doom.

YES! What he said!

Although the T-78 kit is great, a pieced together T-66 kit will be less expensive and, do all or almost all that a T-78 will do.

My only want is to go to the Ball-Bearing version of the T-66.

Hey Mike, did you switch to a divided manifold yet?

T78 & 600rwhp "safely"
 

Okay take a wild guess what this post is about? Okay so maybe the 7 I was looking at (everyone looking for a T-66 CYM see Ebay right now) wasn't the right one. But maybe I've found another so I'll go on searching until I have the right FD, ready to be modded to hell and back. So a T78 could do 600 rwhp with some serious boost, correct?

Second question, speaking of divided manifolds, can anyone give me a brief little overview of why they are better, what exactly they do etc. I have heard of this being done, and want to know the advantages and disadvantages, even though I don't see myself doing it anytime soon. Thanks

FD shoppin as we speak

Nope. I'm kinda broke right now. I have the 1.15 a/r turbine housing already. I'll either get the manifold from XS Engineering (cast) or, from crispeed (tubular).

I doubt that either manifold will place the turbine housing exactly where it is now so, I'll also need exhaust work.

I'll probably get the rear end rebuilt before going divided. The rear is gonna be expensive and difficult to have done.

Mike

Didn't the Scoot RX7 make over 700+ to the wheels? I believe it had the HKS T-51R turbo?

Re: T78 & 600rwhp "safely"
 

Ari at RP made over 600 RWHP with the T-78 running like 28 PSI, but there's got to be some SERIOUS porting there.

The divided manifold gives you better exhaust flow to the turbo, just like headers on a non-turbo RX-7. You'll want a turbo with a divided exhaust housing to take advantage of the divided manifold.

I was going to make my own manifold, but I used the HKS cast because it was easier at the time. Once I'm not too busy--probably late fall--I'll probably make my own manifold. You can buy a header flange and a whole bunch of 2" tubing and u-bends from Racing Beat for about $50. Then you'll just need a turbo flange and a wastegate flange. Then all you need is some welding. I bought the parts, but they're just sitting around until I have the time to do it.

I think instead of asking how to make a 600hp 7 that will beat a Supra just tell us how fast you want to go.

What kind of 1/4 mile time would you be happy with. I think it would be easier that way. Anyone can make a dyno queen that shows a reading of 600hp with the right dyno tricks. Dyno pulls do not indicate real life!!!!

Time slips is what matters.....how fast do you want it.

A 450rwhp 3rd Gen is super fast for the street. Spinning your tires at 60 is dangerous and slows you down. You cant win races by spinning your tires.

Also, speed is money, i dont know how much you want to spend but i can tell you that 600hp 7 is MAJOR $$$$$$$$ but it would be a sweet ride

So, just tell us what kind of 1/4 mile you want and we should be able to help with that....you might not need 600 hp to achieve your speed goals.

Later,

Yup, there's a video of the dyno run somewhere out there.

the video of the Scoot RX-7 is at www.rotaryextreme.com

I was too lazy to look for the URL earlier, but you can see the Scoot dyno run, as well as ALOT of cool videos at http://gallery.rx7club.com/videos/videos.htm .

Just going back to the earlier comment from FD_Pilot about there being only 2 RX7's in the world making that kind of power...

http://www.hitman.hm/rx7.htm

I beg to differ :-) The world does not end at your US borders.

My car has about 400rwhp. I run mid elevens. Of course, my car is LS1 powered coupled to a 6-speed. The torque curve with the better gearing makes my car way more streetable than most single-turbo 13b. I've seen a guy with about 375rwhp doing 13.1... what a joke. For me it was much cheaper to swap to an ls1. V8's aren't as bad as most people think they are. I will never have to worry about seals and temperature again, not to mention gas money.

I've just begun driving my FD with a T-66. I'm only running 10 psi, and it is really fast (I know that means nothing). The guy who owned the car before me did most of the modifications. The engine has a large streetport. He was shooting for 600 rwhp. I don't know at what boost level he was expecting that though. I plan on upping the boost to 15 psi in a couple of weeks and then dynoing the car. I'll be sure to update everyone on the results.

Just going back to the earlier comment from FD_Pilot about there being only 2 RX7's in the world making that kind of power...

This is false.
Mine does just over 600rwhp and is for sale. Marcos Acosta built it. I am selling it because I have moved out of the country. Very streetable. Check the single turbo section and look for my name.

Just a report from the street about T66 RX-7s and power... I know a guy that built a T66 setup that put down 497 HP at the wheels around here. I am not sure that is the limit with that turbo, but it is at least one data point. I think he is still working on it, and may post higher numbers in the future. But I was impressed with the 497 -- that sounds like one hell of a fun ride to me. :)

Damn, talk about back from the dead....This thread is over 2 years old lol

STEPHEN

Yeah, blame Mr. Gas money saving, 400hp LS1 man :)

the forumla for 600hp is realllllly easy:
Get 300hp and drive it all the time
Get 400hp and drive it sometimes
Get 500hp and drive it once a month
Get 600hp and watch it sit

Just for the record a T66 will do 600+RWHP (American HP that is) with some good octane gas on a street port 13B :D

haha, i was waiting for a post like that. . . good call carson. haha

paul

Yogi, after all my wining, and I ended up with a T66;). I am starting with a .81 Q trim, we shall see, The cars getting a widebody, to fit 335s on chrome moly axles right now, then the new turbo, we shall see:D.
Louis, there is one other category, never try it, never drive it. Oh, and be afraid, very afraid(500+rwhp).............:D

I will be driving mine more then once a month. ;)

all this fd talk and 600 hp;)..what about the fc? there is/was a member making 620rwhp on his fc running a t51 kai. and several are running the t66 and making almost 450hp (last time i checked, may be higher now) running a half bridge. yes the fd is nice but the fc may be cheaper to make that much hp.

yeah sorry about the bringing back from the dead thing..i had to post..:D

The FC you're talking about is Soul Assassin. That cars been dismantled in the last year. The cheapest/easiest way to make that kind of HP #'s is to go with a carb'd V8 unless you can do all or nearly all the work yourself. If so, the 20B is another option to consider to keep weight down.

Agree with SPO with what speed do you want to achieve. Other factors contribute such as gearing, wheel/tire, suspension, etc, not just big #'s.

i wonder if that dude is still on the forum. He was prolly just another kid talking about how he wants to be on fast and the furious with a 10 second car. I bet he didnt get one.

Yeah, so this thread is back, and I guess I'll give an update. I made 410 RWHP at ~16 psi on a fairly conservative tune a few months ago. I'm planning on cranking it up to 20 psi in the next few months and won't be happy unless I get 500 RWHP!;)

600RWHP? That would be insane! I can't even imagine...

I need to get my wheels so I can get my car off jackstands, and crank up my .81Qtrim T66. Carl
BTW, 16psi, come on.....................let's go;)

Yeah, Yeah. I know;)

pussy:D


j/k impressive. whats your quarter mile times? or did i overlook that somewhere?

explaining
 

its traction issues

"breaking loose" = wheel spin on dry conditions...in this case.

:mad: :D Actually, I haven't been to the track yet. Hopefully sometime in the next month I'll be going.

good luck show up those damn pistons ;)

I have around 300rwhp and im running mid 12's (12.4@118)

I think your boy with 375rwhp needs to learn how to drive. FD's with ~400 hp have made 10's

I think you can see some better times with your setup. What tires are you running?
