  2. HP limit for WRC?

    I've noticed that just about all of the rally cars on here have 300hp or 299 or something like that. I assume that the WRC limits this? Just wondering cause I didn't think it was some kinda of coincidence.
     
  3. To answer your question, yes there is a HP limit in WRC. There are also many other limits to make the cars as close as possible to equal performance. This makes tweaking and car setup a heavily important aspect of WRC, and puts an even bigger emphasis on driving skill. The way racing was intended to be.
     
  4. Not that i have any prior knowledge to answer the question, but i think there's a displacement limit.<!-- Signature -->
     
  5. Yes there is a displacement limit. If not then you could build a huge engine with 300 hp but huge amounts of torque. Most international series do have a rule on displacement.
     
  6. Alright thanks guys I was wondering about that.
     
  7. I noticed this too in GT3. I was like, why are they all the same. SO I made my fto lm race car my rally car.<IMG SRC="http://www.supercars.net/servlets/cMsg/html/emoticons/smile.gif"><!-- Signature -->
     
  8. there is a limit on the surface area of the intake for the turbo, and for displacement, but the fia doesn't have a hp limit, the specifications it allows should keep power down.
     
  9. I think the companies have to claim to produce 300hp. but the competitive teams are still putting out 430-480hp.<!-- Signature -->

    Is this true ????<!-- Signature -->
     
  11. Due to a restrictor in the car admition, it's power is not much more than the 300bhp, officially declared and admited by the WRC regulation, seeing that above the 5000rpm the engine "breathing" is very hard, being the main superiority the massive torque (more than 500N.m.) that this engine produces from 2000rpm.

    Sorry, i was just trying to say that thay are oficially "limited" to 300bhp by the use of a restrictor in the car admition.
     
  13. Some of the press releases I've seen claim that their cars produce 400-500hp.<!-- Signature -->
     
  14. What about the Suzuki Escudo???? 900 somthing horsepower????
     
  15. i need more posts
     
  16. It was a privately fielded entry at Pikes peak. It had two motors and huge turbos.<!-- Signature -->

    The Monster Machine is what this moster is often refered as. The Suzuki Escudo Pikes Peak Version started running in the annual Pikes Peak Hill Climb in Colorado in 1997. It won for two years straight, and was driven by a Japanese madman. Powered by (count 'em) two turbocharged V6's, one in the front and one in the middle, this monster machine was the fastest competitor in its time. To keep it on the ground, a giant sized spoiler was mounted on the back, along with side front skirts to keep the nose down. With a top speed of well over 200, this was the meanest, most non street legal Suzuki ever created, besides the Cultus. But it's retired now, sadly. At least Suzuki has the chance to take it out on the track every now and then...

    This is one of my favorite cars. I never knew it existed until Gran Turismo 2. I looked it up for real, and I know this think would some just about anything. Vetts, lambo's, vipers, saleen, cr-5's, and so on. Just smack some slicks on there and letter rip!

  18. Those are some cool pictures. I was at Pikes Peak the year Millen(celica) and Tajima(escudo) raced each other in the unlimited class. It was time trial, but it was still cool.<!-- Signature -->
     
  19. There is a 300horsepower limit in the WRC cars there is also a 34mm restrictor that is to be placed before the turbo to restrict power... most manufactures say there car has 300horsepower but if you work it out (2*pi*torque(in NM)*given RPM / 60,000 you get the power output at that given RPM and if you work it out even at 4000RPM most of these car put out more power than they say they do...so I think you get the idea that the power limit is a Farce the FIA doesn't enforce it

  21. thepupat was exactly right in what he said. All WRC cars are told to fit a 34mm restrictor to limit the powers under 300hp.

    The weights of any WRC spec car (not the old Group A specs that Evo 6 ran under) are 1230kg. The basic rules are that the car must have 5000 units sold of the base model car (in other words, 5000 normal Impreza's or Focus's must be sold), the WRCar be 4WD, have a 4 cylinder 2.0L turbocharged motor and have a claimed power output of under 300hp. In reality the motors are all producing in the 330-350hp region with the FIA restrictor because unrestricted, all these cars can produce in excess of 600hp. C yas!! Mafs!!<!-- Signature -->

    "Bhp / Liter 492.99 bhp"



    whoooaaaaa hold it right there. . . your telling me that each of those V-6 engines in the escudo is only one litre?!?! bull. . . i dont think that is correct. . . there is no possible way that is correct. . . <!-- Signature -->
     
  23. Hard to tell, is kind of a small engine. I don't mean it doesn't have power, but it seems pretty quick. I wouldn't think it had a limit though. But what do I know.
     
  24. but 500 hp per litre??? thats absurd. . .there is just no way. . i can almost believe 250 a litre. . . even though thats still very high.. . <!-- Signature -->
     
  25. The Suzuki 'Pikes Peak' Escudo is NOT a WRC car.

    All cars in the WRC are 'limited' to 300 BHP through the forced use of a 34 mm restrictor in the air intake into the turbocharger. (It isnt really a power limit, but the restrictor means the teams can only realistically get a few BHP above the 300 BHP magic number)

    All the engines are 2.0 litre, 4-cylinder, turbocharged and produce approx 300 BHP and over 500 lb/ft of torque.<!-- Signature -->
