 Any experience with straight cut gears in a 914?, I'm thinking about it when I do the scooby swap. |

I have been mulling over the idea of running straight cut gears in a 901 or G50 when I swap in the STi engine. Was wondering if any of you have run or are currently straight cut gears in a teener. I kinda like the sound and the extra strength. I'm not too worried about excessive noise since the setup I'm running will be loud exhaust, loud turbo and VERY loud blow-off valve.
What are past experiences and opinions (with reason as to why you feel that way)? I've searched but have not found what I'm looking for. So if this has already been discussed then please just point me in the proper direction. |

(IMG:style_emoticons/default/biggrin.gif) 1st off, do they exist for our gearboxes?? If so, have you priced them?...I'm guessing they'd be in the $5K - $10K range easily.. They are aviable for the subys I'm pretty sure so it would be a no brainer just to use that transmission.... |

All of the Hewland and MK5 gear sets are based on the same pinion and input shaft spacing as our 914/901 boxes.
Our tranny is a glorified VW box. Can he do it? Yes. Will it take some potential special parts? Yes. Benefit on the street? None. Benefit for racing? Lift throttle clutchless upshift (or full throttle depending on how often you want to replace the gears) or ignition interupt upshift. B |

If I do this it'll be a weekend warrior/SCCA circuit car at that point. So I'm not looking for benefit on the street. Only on the track. And this is just a thought. I may or may not actually do it. And you've gotta admit. Clutchless upshift would be pretty cool. Now if only there were a way to run a sequential trans... for a semi-reasonable price. (IMG:style_emoticons/default/idea.gif) |

John,
gears aren't that easy to make they are hardened too. there is a reason that 901 reproduction gears are selling for 500-700 a piece now. lots of ways to spend money with more returns on a 914 than this the G50 is going to be a bunch of weight... use the least/smallest/lightest box that your powertrail will allow. brant |

I'm not too worried about the straight cut gears, I just thought it was a cool idea. My setup will start just over stock at about 320 at the crank or so. And when I decide I want more, which most of us always do, it'll be bumped up to the 475+ area. |

You will never use the G50s strength plus it is a very large tranny and twice as heavy as your 901. There is no reason to go to straight cut gears on the street. It will be noisy as hell. It would be cool for about 30min. After that you will pull the box out and put it in the corner.
You will be so outclassed in what ever SCCA class you can run your car in. I would focus more on suspension and brakes. If you want to go to a more modern tranny look for a Boxster tranny or the Subie tranny. |

I used to stoplight race my bug against cars that I stood absolutely no chance against; like a GT2 and a 360 Modena. Knowing I wouldn't win didn't make it any less fun. |

Them roler bearings in the brass housing is what goes quickly first if I'm not mistaking. Can't we upgrade that component at least and weld the case up like they do for VW tranys?

Why not use the Suby tranny? Am I missing something here? not sure why anyone would use a 30yo tranny behind a Suby engine.

There won't be a race. There will be you riding around a race track getting passed by most of the other guys in SPO. Which is an unlimited class.
You will be competing against 700-900hp fully prepped cars with what is vitually a street car. You will spend the whole race looking in your rearview mirror. Why not use the Subaru gearbox. It is a much better design than the shitty old 901. |

The first rule about racing has always been and will always be to read the rule book first.
then build the car that fits into that rule book. otherwise you are not really a racer.. you are a hobbyist that likes to drive around in circles non-competetively. Racing is about being competetive and trying to win. I find great joy and accomplishment out of trying to use rules to my advantage and challenge about trying to remain honest and stay within them. In my opinion, that is a huge percent of what racing is really about. Trying to out think, out fabricate, and also out drive the next guy. Thats racing.. otherwise its just a car hobby. I'm not trying to unload or be rude. This is bigger than just you and your plans. I have this feeling often with other guys on this club and wish that they could see why I push them and how much they would enjoy it if they had that insight. brant |

I just wanna push my car without being arrested and having my it impounded. However, I've yet to find any decent time trial opportunities in the local area. Honestly, if I could shut down some back roads, some nice curvy stretches heading up into the mountains over here, I would rather do that. Unfortunately, that's not an option.
