TomsCoupe Posted August 26, 2004 Share Posted August 26, 2004 from the RB26DETT out of the skyline GTR but just how reliable are these engine at 800+ hp? I mean, 1200hp out of a straight 6 is big numbers. So yeah, how reliable are they? Ill pobably never afford it, but i was just wondering.

Guest bastaad525 Posted August 26, 2004 Share Posted August 26, 2004 Very. But, those guys pushing 800 or 1200hp aren't doing so on stock internals, so at that point it becomes nonrelevant. The most common number I hear for the maximum power the RB26 can live at reliable is about 600hp. The Supra twin turbo's motor is one that is also legendary in it's ability to withstand very high horsepower levels even on stock internals... one of the most reliable and strongest motors ever made, that one. Guys have hit 900hp TO THE WHEELS (well over 1000hp) on dyno's, running stock blocks/crank/pistons/rods. Quote Link to comment Share on other sites More sharing options...
TomsCoupe Posted August 26, 2004 Author Share Posted August 26, 2004 that insane. the 2jz gte is such a huge engine though. But damn, 1000hp on a basically stock long block. Quote Link to comment Share on other sites More sharing options...
johnc Posted August 26, 2004 Share Posted August 26, 2004 I hear those wacky numbers thrown around all the time. But, I know a number of guys that race MK3 Supras on road race track and all keep the power turned way down because the constant rpm swings (full throttle, off throttle, full throttle, off throttle) tends to make the engines go boom!

280z-racer Posted August 26, 2004 Share Posted August 26, 2004 the HUGE number guys are either dyno queens or drag racers. auto crossers keep the power down because they are on and off the throttle all the time. Quote Link to comment Share on other sites More sharing options...
Guest 81na ZX Posted August 26, 2004 Share Posted August 26, 2004 Right. Look at the power curve on a 1200hp supra some time. you get 1000+ hp from 6000 to 8000 but like 200hp before that. 100% unuseable. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted August 26, 2004 Share Posted August 26, 2004 I'm finding at 9psi boost/stock turbo on my L28ET/240z that I have almost too much power for autocross too... it's all about traction, not power! Quote Link to comment Share on other sites More sharing options...
JMortensen Posted August 26, 2004 Share Posted August 26, 2004 Another possibility: My Z made 850 hp when I was running SU's, but now that I've switched to triple Mikunis, it pulled down a whopping 1237whp at 46,000 rpm. Just because I said it doesn't make it true. OT- I can't believe that there is such a thing as a "dyno queen". That's gotta be the single dumbest reason to build a car that has ever been.

Guest Cronic Posted August 26, 2004 Share Posted August 26, 2004 A supra that has a 2Krpm useable powerband usually stays in that powerband when it's built right. Otherwise, it's just bad building expierence IMHO. Quote Link to comment Share on other sites More sharing options...

[/quote'] This isn't hearsay, the same guy had his supra featured in a couple magazines, SCC and Dsport I think (I have too many darn car mags lying around) and they published his dyno sheet, so I kinda think this is the real deal. Of course, who can really verify if his block is internally stock? *shrug* I'm usually a skeptic but I believe the 900+ hp number on stock internals is the real deal. Does he drive it at that power level all the time? Of course not. Does he make that power on pump gas? Of course not. Would his motor get 200,000+ miles at that power level? Of course not. But fact remains, you can abuse a Supra motor a hell of a lot more than just about any other motor out there, and still drive it home afterwards. That someone nearly QAUDRUPLES the power on an already powerful motor running stock internals is just a testament to how well built and strong that motor really is. So for me it doesn't matter that you couldn't drive like that on the street, I'd just be glad knowing that the motor could take whatever power level I WOULD run on the street all day and night and not even break a sweat.

JMortensen Posted August 27, 2004 Share Posted August 27, 2004 I'm not saying it is or isn't hearsay, and I'm not saying that a given Supra can't make 1000 hp. I'm just saying that many people talk from a hole that can't enunciate when they start claiming hp. Quote Link to comment Share on other sites More sharing options...

crazy280 Posted August 27, 2004 Share Posted August 27, 2004 I don't post often, but my extensive magazine collection might help here. The current September issue of "Sport Compact Car" has a story about a Supra making 991 RWHP and running in the 9's NHRA certified. The December 2002 issue of "Turbo & High Tech Performance" has a similar story about another Supra- the 2002 NHRA street tire class champ- running 9's, with 949 RWHP and the dyno sheet to match. But both of those cars had built bottom ends, due to extreme boost (30-40 psi). SCC makes the comment: "Although the stock 2JZ-GTE bottom end has been shown to support more than 980 whp, with the frequency Ryan planned on hammering the car, he decided a built engine was cheap insurance against dropping oil in front of the rear tires at high speed." Soooooo, in other words, it's possible to build a stock block 2JZ with over 900 whp, but it ain't gonna last very long. So maybe 900+ whp is not really gonna happen on a stock block, but according to the driver of the class champ Supra, 600 whp is common on stock block 2JZ's these days, and 600 whp is nothin to laugh at.

Guest 240Zduz10s Posted August 29, 2004 Share Posted August 29, 2004 Right. Look at the power curve on a 1200hp supra some time. you get 1000+ hp from 6000 to 8000 but like 200hp before that. 100% unuseable. right but most people who have 1000 hp supras probably realize that its gonna take a big and laggy turbo to make the power they want. throttle reponse and power delivery isnt exactly a high priority. besides even if the power curve sucks they still rock on the freeway and no one would consider it to be slow, so 100% unusable is a subjective term .. its probably unusable in a auto cross situation, but in a drag race, or freeway sprint with bullet bikes, (which they obvioulsy build the cars for) is hard to beat. i would rather have a laggy 1000 hp supra than a responsive 500 hp corvette anyday, but the funny thing is they would probably be the same speed in the 1/4 mile:) but not on a freeway, it just depends on what you want to do with the car.

Scottie-GNZ Posted August 30, 2004 Share Posted August 30, 2004 would rather have a laggy 1000 hp supra than a responsive 500 hp corvette anyday, but the funny thing is they would probably be the same speed in the 1/4 mile:) but not on a freeway, it just depends on what you want to do with the car. Would like to reassess your opinion after you have driven both for a couple of weeks, unless you are just into having the biggest number. As for the 1/4-mile comment, I think you meant ET not speed. With 520rwhp my best was 10.08 @ 134.44. An acquaintance(well known in the Supra world) had "1000hp" on his tag and his best 10.42 @ 142+. MIght be off a little on his times but not by much. As for being the highway bullet, I have my own opinions on running a 1000hp car flat out on public roads, any public road. Quote Link to comment Share on other sites More sharing options...
Guest Chris240turbo Posted August 30, 2004 Share Posted August 30, 2004 Listen to "THE MAN" Scottie GNZ, a fellow I have never met, yet respect more than most people I know well. I used to be a "street racer" and still own a nitroused big block '69 Camaro I've owned for 15+ years (does that make me old?) I once arranged a money race with my 1 year old son in the car. (he didn't ride during the race, but at the time I remember thinking what an advantage I had working a race with a toddeler in the car, jeez I was a dumba$$) I now have 3 children, my son who is 10, and 2 daughters, 6 and 1 (just turned 1, 2 days ago) and I sometimes wonder how I made it this far, having done some of the wreckless things I have. For every "cool" street race story I could tell, yet never will to my own children, I have a story of someone getting divorced over the money spent on the car, getting hurt, or a couple of times killed, or getting busted, and doing jail time while thier pride and joy was picked over at the impound because of serious drag racing on public roads. Mind you, I still lay into the throttle for a few seconds on puplic streets, but this is nothing compared to actually racing... For a while in my life, all I wanted was the fastest street car anyone had ever seen, to make everyone wish they had built a car as bad as mine. Listen to Scottie, whose GNZ would have surely put the hurt on my old Camaro, when he asks "how much is enough?" because, if you ever come close to the limits of a 500whp C-5 'vette on the street, and I'm there, or do a serious highway run against a 1000whp Supra, and I'm in a vehicle, with my family, and I see you, I'll be the first "a$$hole" on my cell phone, and I will provide a description, and pull over with the PD, and identify you. Engage such noble persuits on a closed course please, and I don't mean the most deserted road you can find, I mean a track, after all, you spent all this time and money on a rig you think is fast, are you now to scared or broke to take it to the track? I believe slow crap races on the street, for the most part, either that or the drivers that need to inflate thier egos picking on street stuff. Bottom line, if you think your car performs, Crondeks don't lie! Also listen to Jon and John, a couple of guys who own serious track cars, that just happen to be street legal, just because you read something in a magazine doesn't make it so, do you honestly believe there is some kind of law that makes editors and story writers tell the truth??? PLEASE, they are out to do whatever they can to sell the most magazines to the most people, to MAKE MONEY, I'm not saying that the cover car on SCC didn't make 900+ hp, or that he didn't run a 9.xx 1/4 mile in a manual trans car, I'm just saying I think it makes for a better day dream than reality, if you were to actually talk to Brian Woon, I bet the build up of that car was anything but "he bolted on some parts, "built" the motor, and ran 9's, and now he'll squeeze the thing, bolt in a TH400, and run 8's, grow up, this kind of thing is NEVER that easy... If you are serious about building and owning a fast/quick car, there are countless avenues open to you, your local dragstrip, (if there is not a 'strip close to you, and you race on the street, and you kill an "innocent" I hope you burn) or top speed wise (something that sparks my interest at least a little, might be time to pull the old Camaro out of storage for a rework!) you should check out these sites.... http://www.openroadracing.com http://www.bborr.com http://www.silverstateclassic.com Regardless of what you might read on the internet, truely FAST street legal cars, like the GNZ, are few and far between, and I'd like to think, that by the time you have the wherewithall to build/buy/own a car such as this, you have some respect of the fact that such a rig can be extremely fun, and even educational, while you have also garnered some respect of the effects of such a vehicle, driven all out on the street, could have should the driver become a passenger! I wish some of the younger generation would learn from the expieriences of some of the older generation, but they probably won't, after all, I didn't. At least you can pray that luck is on your side, and you don't turn into a street race story some "old guy like me would rather not tell.... Sorry for the rant, I never have before on the 'net, and I likely will never again, it's just when I read posts like "500whp in a street car is not enough" I guess I turn into the old fogey for a moment, that said, I hope my new 60-1 T4 turbo set up makes 400whp, but whether it does or not, you can bet I'll be on a track of some sort when I get serious about dropping the hammer!

Guest bastaad525 Posted August 30, 2004 Share Posted August 30, 2004 I'd take a 250-300rwhp, well set up 240Z over a 1000hp Supra or even a 500hp Corvette any day. Well, provided it at least had A/C, that'd be nice Having only ever ridden in one car with that kind of power (think it was 450hp to the wheels, some old Pontiac my dad used to have) and it was just like... what was the point? You couldn't get on it, all it would do is spin the tires. As for top speed... I don't race on a track, so don't need some high top speed that I'll never be able to use. Hell... I don't even need any better handling than what will get me up or down a curvy mountain road alive. Quote Link to comment Share on other sites More sharing options...

Guest 240Zduz10s Posted August 31, 2004 Share Posted August 31, 2004 you guys are right... and i dont race on the street (i dont even have a fast car anymore) but thats not to say that the people who build 1000 hp supras dont race on the freeway.. i dont condone it but that doesnt mean it doesnt happen.. i was only commenting on the power curve, and the fact that anyone who builds a 1000 hp supra realizes that it will lag but they obviously don't care.. and sometimes its just about bragging rights on the dyno...
