Designing variable valve timing or spherical valve - Hyundai Performance Forums

duc450 · 03-26-2002, 02:11 AM

I'm kinda curious why no one on this board or any Hyundai supporters have really jumped in with both feet to start making really killer parts for these cars. I've got all kinds of ideas rattling around in my head. Theres about 3 different ways I can think of to adapt a variable valve timing system to these engines. Also not to mention something similar to the Coates cylinder heads with the spherical valves. Even a five valve head could be a nice addition. What happened to all of the seriousness and pioneers of this sport? Now everyone slaps on a turbocharger, supercharger or nitrous kit to go fast. Don't get me wrong this is a great way of doing it and some actually require a little thought in the process. But where is all of the really radical stuff like rear wheel drive conversions and v-6 and v-8 conversions? I guess what I'm saying is where is all of the support? I guess thats why I've decided to try and fabricate my own parts. I've got a set of 13" rotors and PBR twin piston calipers that are just waiting to be fit to the front of a Tiburon not to mention changing over the useless four lug bolt pattern they put on these cars. Well I guess I just needed to vent a little. I'm sure there are some people that are just going to hate this post but there always is. Thanks for letting me vent!

I for one can agree with you to an extent. If I had the knowledge required to do some hella mods on my car i would do it in a second. However I'm working over 50 hours a week and don't have the money (go figure). Also I'm still a novice when it comes to auto maintenence and whatnot. I'm learning though. I successfully incorporated "TDC" into a conversation yesterday! <img src=/images/forums/snitz/eek.gif width=15 height=15 border=0>

Most people who buy Hyundais are not SERIOUS tuners. Give them a little bit longer and you'll have more and more junkies popping outta the woodwork. Us MN members are leading the Hyundai way up here.

Right now I'm working between 60 and 77 hour work weeks(It's tough when your the boss and everything comes back on you). I just think it would be nice to some how get the Tiburon in the same arena as a world class super car not just a sport coupe. Once things calm down at work I'm going to start some designing in TurboCAD. Strut bars and all are nice but there is so much that has been untouched by the aftermarket.

Right now we're still trying to perfect simple things like true "bolt-on" cat-backs and headers that require no drilling of O2 sensor bungs or welding. We're also just now about to get a truly complete bolt-on turbo kit. Once the easy s**t has been perfected, then people will begin looking for innovative new ways to make more power. I'm currently working on something now that can be used on any car, not just Hyundais. I got the idea from my experience with sportbikes. No, I'm not telling anyone what it is because I haven't applied for the patent, yet.

um..slapping on a turbo charger isn't all that easy yo! Speically when you go and take your engine appart to do internal modification so you don't screw anything up. Don't forget about piping the intercooler and stuff. A semi-experieced person takes about 3.5 hours to install a dry nitrous kit. So um..not only is doing major modifications a little hard, it is expensive and it also takes time.

Um .... maybe cuz your average John Q. Public 18-25 year old doesn't exactly have the cash on hand to whip up a 5-valve head, or that variable timing system on a whim. Give us a break dude. Sheesh

I think Aaron knows this much. I believe he is speaking of a simple daily driver that won't require major mods... hence "bolt-on" <img src=/images/forums/snitz/moon.gif width=15 height=15 border=0>

<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>Duc...what you're talking about is a full-on competition conversion!!! The 5-valve head like the 4A-GE will have to be factory made, so will the spherical valves. There is potential for the incorporated Variable valve timing, but I doubt our computers would be able to support a piggyback module to control the lift angles and monitor the fuel to air ratio at the same time. It IS possible, at a show in Japan not too long ago one of the more mentally disturbed garages built VVTiL into the intake cam of an RB26DETT...no figures were released.

Please note though, these processes require moderate to extremely sophisticated tooling and testing equipment, especially for the 5-valve/cylinder head and the VVT...the processes would cost simply too much for an individual, and garages mainly do this kind of thing to showcase their abilities, not for public distribution. Keep your modification as simple and effective as possible, going down this path will lead you to insanity; the more prototyping is necessary the more equipment failures will become frequent...this is why garages and companies have TEAMS of engineers...so no one individual goes insane within 24 hours. It usually takes several years for that to happen...and the result is companies like Top Secret, Top Fuel and RE Amiyana.<img src=/images/forums/snitz/laugh.gif width=15 height=31 border=0>

I agree its alot of time and effort. But thats why I enjoy it so much. Like you said garages do it to showcase their abilities. I'm in it for exactly the same reason. Everything you said is true from the equipment failures to the limits of the stock computer. But just when people go and think something can't be done, it happens. Like I said I think the enthusiasm that used to exsist in this sport has died down some. I'm just looking to create my own.
