      I know. Just messing with ya. I wanna be an engineer when I grow up though.
      Ever see a black hole gobble up a solar system? You will see it when HPA's BT kit is released.

      I understand when you get to a new turbo setup you would need to change fuel pumps but not just with a tune.

      Also, people are saying that you can feel a difference with a new HPFP even without a tune. That tells me the car was designed incorrectly...

      I love my R, its a fun toy but $1000 for a fuel pump so that we can upgrade the HP is insane...

      With all of these awesome cars in your past you MUST understand the importance that fueling plays in a higher than stock HP car. Most BT kits have either an in-line or new in tank fuel pump and in our case we need to replace both the HPFP at the engine and the low pressure pump when going to a BT setup. There is no difference in feling with the HPFP installed.

      But...since you know better then any of the tuning companies, I'll be waiving at you in the mirror when you hit fuel cutout and can't figure out why you are so far behind!

      That's what I said, I know better... Read what I posted again... I know it has to be changed but I think it is insane that we have to... Volkswagen should have engineered it better.. Before you flame again read the post...

      VW engineered a good fuel pump. Why should it be their concern about whether it is good enough for stage 2 software?

      I don't think you're going to win over any allies with your argument. You're upset because, in your opinion, you believe Volkswagen should've engineered the HPFP to allow in excess of 500hp from the factory. Seriously? Of the 30+ cars you've owned, how many have been direct injected and even use a HPFP?

      How many of those cars came stock with a cam driven HIGH PRESSURE fuel pump? I would tell you everyone claiming that they feel a difference with just the pump upgrade on the stock tune is full of ****. The tune only requests X amount, and it will only inject X amount.

      All those cars and all those upgrades.. you should be able to turn a wrench and rebuild your own. Cost me like $350.

      If you want more fast get a more flow fuel pump.

      I guess my point is lost on here but yes I will spend the $350 and build my own... I really do want more fast.....

      I want lots more fast, but this car was not engineered (forget clutch, but the bottom end is not very strong) to handle even stage 3 for very long.

      Proof? Also, how many ~200ish WHP cars have seen that handle ~450WHP with stock internals.

      (Maybe HPA has some input here? With their BT experience?)

      I believe, it would be wise to upgrade your bottom end if going stage 3 or greater.

      But, if the tune allows for safer power onset and control, you may be able to get away with not needing to upgrade the internals.

      You can have 500whp and not blow the bottom end, as long as you treat your car right.

      If you beat on it all day everyday, track the crap out of it, you are going to break something relatively quickly.

      Will leave it at that.

      Same can be said about MOST cars..

      Hell, that's why I have an "extra" $3k hidden away for my Corrado, lol, I beat the ever living **** out of it.

      This is true.
      But, I really think it is a good idea to work the bottom end if going stage 3 and up.

      HPA, I would realky like a GTX30 turbo kit with water/meth please. I know, lag lag lag...

      Volkswagen did nothing wrong...they built the car to handle the power it's designed to put out. They are not going to build something with "extra" output in mind. Don't be so butt hurt...you either pay to play or you sit on the side line.

      Yeah, but Audi did it with the TTRS. IIRC, it can handle dbl its stock power.

      Shoot, even the mk4 R32 could handle a crap load more power than factory power, just the trans couldn't.

      He said "butt Hurt"...


      What does that even mean?


      Anyway, I will pay to play as you say but that still does not make it right. Most engineers during the design phases of a vehicle look into things like this and make adjustments to their design to compensate. Some even review sites like this to see what is expected of their next design. As I have stated in other posts I have been in the OEM automotive business my entire career and know that this is not the norm..


      The designer should have caught this prior to launch... It happens...

      This. There is a Stage 3 car here on the forum that failed due to constant 100 octane. Base Stage 3 should be fine if you treat the car well, but dragging it daily on 100 octane is asking for problems.

      Tell me which vehicle manufacturer designs their cars to handle nearly twice the power output of stock levels and I'll switch brand loyalty.

      Isn't the TTRS motor capable of handling ~750hp? Not sure about their trans though.

      Both my Mitsubishi Evo and Mitsubishi Lancer Ralliart run more then twice their stock output, stock motors. The Evo has been doing this for 7+ years now. I've also tuned a good amount at twice the power that are still ticking.

      That said, both of them have upgraded injectors and fuel pumps, and other bits of course, but the motor internals are still factory stock.

      I can't think of any 2.0L Turbocharged automobiles that do not have to upgrade their LP fuel pump at some point, usually at around 60-100hp more then stock.

      That said, the R does have to upgrade it's HP fuel pump pretty quickly, but that is the nature of it's design, since it is DI and cam driven. I believe the MS3 has to do this as well.

      I'm honestly not sure why this guy is complaining about having to upgrade the HPFP when striving for a good amount more power. You DO NOT have to if you make a nice little jump from stock, but after that, you do. Pay to play. You want more then 50-70hp over stock? Then you need to upgrade your HPFP.

      Again, find a 2L 4cyl turbocharged car where you do not have to do this, buy it, then tell us about it.

      think stew (back from the mk4 r32 days) blew up his evo with less than dbl it's power around 2006+/-?

      but, he was probably another scottisha or worse.
