Hi might be a dumb question but how fast do you think a 914 with a six or four in could go I'm talking like land speed fast. (IMG:style_emoticons/default/evilgrin.gif)
Not a race car with spoilers/wings etc. but a narrow body low slung with tall gearing. Any thoughts other than I'm (IMG:style_emoticons/default/screwy.gif) But the Gt class here in Australia is a soft record ( 2lt class and 3lt) and well !!!!!!!!! (IMG:style_emoticons/default/drooley.gif) |

I know that windshield trim and roofs depart the car above 150 mph.
A 914 is not a good choice for Land speed racing. A brick is not aerodynamic. |

Well, I've had my dead stock 73 2.0 /4 with stock gearing & 165HR15 Semperit M501 tires on Riviera wheels (not even the lighter Fuchs 2L wheels which came on them) up to 121 mph on the Interstate 15 freeway through the Virgin River Gorge in Utah back in the day! (IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/driving.gif)
So your -6 should be faster, & perhaps a slight advantage from hunging upside down on the globe down-under! (IMG:style_emoticons/default/biggrin.gif) PS - Seriously, as Mr. Galla notes, you'd need to do some slight mods to get up to the higher speeds with the trim, roof, probably front & rear spoilers/splitters, remove mirrors, etc. to stabilize it into the 120-150+ range, but I don't really think the 914 is as much of a "brick on wheels" as he says - having seen so many successful 914 racers, & my owning an 1988 T3/T25 Vanagon Westfalia - a TRUE "brick on wheels"!

A brick is not aerodynamic. the 914 is very aerodynamic (IMG:style_emoticons/default/smile.gif) sorry forgot to answer the ? how much money do you have because money buys MPH bottom line |

The stock car's rear end becomes very light at ~125mph. Especially when you drive over one of those reflectors that are glued between lanes on the road! (IMG:style_emoticons/default/w00t.gif)

Besides aerodynamics, check the trans gear ratios. I think the stock 914 gear box with stock gears can't go above 150. I currently have a 86 915 gear box with a 29:21 5th. I could do well over 165 in 5th, but that would be suicide without a makeover. Sheridan kit, etc.

90 is a nice safe speed

A stock 914 will do 120 MPH, given some room to get up to that speed.
A modified 914 can do 180+, but significant power and gearing and aero changes are needed. As 6freak said, speed costs money. How serious are you about getting to that speed? Ah, excuse me--I mean, how $eriou$ are you? --DD |

There are much better—and safer, cheaper—choices for top speed.
A stock 1997 Boxster would do 150 mph, and do it safely as long as everything is in order. The aero is balanced, etc. You can find these cars for well under $10,000—or half that in "less than perfect" shape. Spending a bit more will net you a 996, which is good for 175~ mph with relative safety (at least: it's been engineered to go those speeds). I suspect nearly any econobox today would also be better top-speed choice than a 914, but I know several have been built up for high speed. The good news is not much frontal area. The bad news is the car will need a splitter and a rear spoiler or rear wing—along with a host of small changes to keep everything on the car at speed—to get up there. And then you're still riding in something you really don't want to crash in at high speeds. Top speed is really its own thing. Once upon a time, I did 177.865 mph on dirt as timed by USAC—with the tail wagging all the way down the course from 145 mph on. I got back and everyone asked, "WASN'T THAT THE BEST THING, EVAR!!!???" No, I thought. It was kind of interesting and more than a bit sketchy—and if I never have to do it again, that'll be fine with me. I've driven and ridden at higher speeds than that on the autobahn, and the reality is that there really isn't much skill involved—you just need good vision and the "courage" to keep the pedal pinned. It's neat once, but then it's just huge risk. At least for me. Some people really enjoy super high speeds. Me? I'll stick to cornering and flowing roads and race tracks, running 30-80 mph—and maybe 100-140 mph on track. I just find cornering more rewarding than straight-line speed. That's not to say I don't have respect for those who are into drag racing or top speed. And, fortunately, there are some really cool events for the top-speed people in this country—from Bonneville to half-mile and one-mile events. |

All the simulations I have done with my current setup say I should be able to get close to 200mph at my high power setting and current gearing...
Will I ever do that? Not likely... Most I've done is 150, and the rear end gets extremely light at that speed. Serious aero would be required (Full undertray front to rear) if someone was serious about going big speeds (180+) in a 914. |

Hi might be a dumb question but how fast do you think a 914 with a six or four in could go I'm talking like land speed fast. Depends on the transmission and your rpm limiter. The stock 901 tops out around 135mph at around 6.5k+ rpm. I've been there ... (IMG:style_emoticons/default/driving.gif) |

A 914 is not a good choice for Land speed racing. A brick is not aerodynamic. The 914 has a better CD than a 930 turbo. The only brick i can see is the one looking at the 914 ... (IMG:style_emoticons/default/biggrin.gif) (IMG:style_emoticons/default/poke.gif) |

I know Tony (Cracker) has done about 156 in his....but that's with a wing/splitter/wide body...and LS engine. I've topped at 140 but I know the aero needs a lot of work so I'm hoping to get 150 eventually.

Gearing will not be cheap.
You might want to look at those costs first. Body wings etc are all available easily. Gearing is not as easy to source. Tall tires are a quick way to change the ratio |

Not a race car with spoilers/wings etc. but a narrow body low slung with tall gearing. I had my slightly lowered narrow body with no sways up to about 120 mph going down a BF'in long hill. White knuckles, my seat is now brown. I could feel the ass end getting light, like being on ice. I'd want my NB teen a hundred percent sorted before trying that again. I say about 120, because of the sketchy handling I was too scared shitless to do anything but a quick glance at the speedo. |

What size wheels can I fit? Group: Members Posts: 4,645 Joined: 5-April 05 From: Scottsdale, AZ Member No.: 3,881 Region Association: Southwest Region |
I've had my 3.2 with my stock 901 up to 130mph(GPS). My experience is that in stock form, the car doesn't feel stable at all at that speed. It gets incredibly light feeling.
Oddly enough, when I was at that speed, LaMonica pulled away from me in his 3.6 like I was sitting still. He just had his tranny reworked. He said he hit 150. I don't know what his speed was but when I finally caught up with him at the hotel he was putting his front trunk seal back in place. (IMG:style_emoticons/default/laugh.gif) |
