 Dealing with the added power..., Good deal. |

My available power on the a/x track is greatly increased due to the added two cylinders. (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)
If I romp on the throttle it steers around into a spin. And I carry WAY more speed into the turns, so more braking is required. There are other Bay Area locals who will have to deal with this as well. Randal, Andy, Nathan, Britain and others will put their new power to the pavement for the first time as well in just a little while. Learning to drive again is fun yet frustrating.

A-Xing is different than track days, but I like to throttle steer. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif) I loved that camera footage you posted the other day. That rocked. I am working on getting my six together. Just have a few other things to button up and I can get back to work on my own project. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Couple of things....you can dial in a little understeer, soften the rear springs, add an LSD if you haven't already....
BTW...I know this guy...he has an LSD equipped trans all ready to go.... (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) |

Are you sure that front air dam isn't catching on the ground and causing you to spin? (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

The four only saw a small increase in temp. I doubt it's that big of an issue. |

The Sweeper Dam is my friend. (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif)
With the giant cooling fan on the SIX, high temps are a non-issue. Keep the feedback coming so I can take the 914Cup...What?...Whoops. (IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif) KT |

Heh..... at my first AX after I removed the 2.4 & put in the 2.7, I got maybe 200 yards before I was going backwards (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)
I never AX my car when it had a t-4, but I AXed JimC's car last summer and was amazed by how easy it was to drive....foot to the floor & steer. With even minor changes comes a learning curve & spins/daid cones are part of that.....I do this every season (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) In my experience, 914s give little or no warning rear end of break away. To have to learn to anticipate that.....you kinda get a feel for it thru G loads. They definitely will spin while trail braking....that can be used to an advantage, but if your going too fast, nothing will save you (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) .....butt time is the key. Straight line braking is good till you learn to anticipate. If it's pushing, a *big* lift on the go pedal will bring the back end around......but be ready to counter steer and jump back on the go pedal. I got to practice that on a skid pad last year. A little lift won't do it, but get it right and I could dirt track around half of the circle...not the quick way around, but it will save a run. If you're not looping the thing occasionaly, your not trying hard enuff.....to often and you're pushing too hard. .....the red mist. You can't learn under the influence of the mist. |

nope ... his airdam does make the (4 cyl.) engine run hotter. doesn't matter much for AX, but on the big track, you'll see a significant rise in oil-temp. the 4 cyl. cars *need* a significant air flow under the car for cooling. they even added the "flaps" on later cars to enhance the effect ...

If the ass-end is swinging around on you taildragger style... You can do a few things as mentioned above. First thing I'd do is look for some better gripping tires and corner-balance it, preload the suspension accordingly to get 50/50 or as close as possible.

Thanks, JP.
I was still coughing up a little red this morning. (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) Seat time. Where have I heard that before? (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) My tires are Yokohama A032R's treadwear of 60 or Hoosier R3S03's with treadwear of 40 (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) . Without going to non DOT tires, it don't get much schtickier (IMG:http://www.914world.com/bbs2/html/emoticons/cool_shades.gif) My problem is ME. There I said it! ME, ME, ME!!!

I suppose the air under the car is used to cool the oil in the sump - hence why the sump has fins on it.
I bet Jake knows the deal with this..... I also wonder how it effects engines on the dyno - do you have to create false airflow to keep the engine from overheating? |

(IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) the airflow under the car helps to move hot air away from the underside of the engine and exhaust. has nothing to do with the fan intake on the top ... they added the flaps just in front of the engine on later cars to create turbulence (sp?) to suck out even more hot air from under the engine. if you run a big ass front air dam, you don't get much airflow under the car thus not moving any hot air away from the underside which in return increases oil/engine temps. as i said before, on an AX, the runs are so short, it doesn't matter much, but on the street or on the big track, you'll see a significant raise in engine/oil temps if you run a air-dam like trekkors ...

Yup....seat time an ONE adjustment at a time. I was a rather competenet AXer with my 70 2.0....took class wins more than a few times. Converted to a 3.0 and I was turning in slower times on the same courses....took me about 12 events to get back to where I was before.....
Patience......screw it....I want it NOW..... (IMG:http://www.914world.com/bbs2/html/emoticons/dry.gif) Ahem, ignore the kook behind the screen.... (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) |

I will be putting this to the test here next week. My son whacked a cone about 1 foot from dead center. Smashed the shit out of the cow catcher air dam. So I will go back to the early nose cone / belly pad. I bet it will really affect how the car handles on the freeway @85MPH BTW this is where I get the engine warm 345 with oil temps near 220. Takes about 75 miles to get this warm and levels out about there.
So stay tuned. WISH I HAD MORE HP!!!!!!! Getting braver with my 4 as I have my foot planted to the floor lots more now. 6000 RPM shifts 2nd to 3rd back to the floor till I reach the next feature sometimes I lift, Most always lift for the slalom just can't steer that fast. |

Trekk,
You might (prolly already have, knowing you... (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) consider going 5 lug to add the 911 brakes. That would make things a bit more "in control" |
