I think stock 914's are very forgiving cars and are easy to drive close to the limit.
When you start "improving" the car is where it starts getting interesting. Changing the suspension will just make the car more fun to drive. It's when you start doubling or tripling the hp, race car suspension, full cage that ties in the suspension points, larger tires and wheels, bigger brakes, losing weight, that makes these cars a handful as they are nowhere near as forgiving as a stock car.
The stock car is a momentum car that allows you to carry more speed thru the turns to make up for the lack of power. When you start increasing the straight line speed with a large increase of power you have changed the equation so the car is no longer a momentum car as you have to drastically reduce your speed for the corner, start your turn in, and slowly apply power thru the turn.
I'm a bit at a loss as to what this all means.
In my experience....starting with a stock 914 with NO anti-roll bars & 95 hp, I found the STOCK 914 very unforgiving. It would spin like a top.....with no warning.
Various progressions in hp and moderate suspension/tire "improvements" cured much of this, tho I admit that at one point the thing was nearly undrivable.
In it's latest iteration, the car is much more forgiving.
It can be a handful (one must be carful with the loud pedal), but the speeds are much higher, both in a straight line and around corners. Tho my driving skills are marginal, I can make it push, oversteer, or be neutral....all in one corner. Recovery from lurid oversteer is now possible.
Like I said, my driving sux, but here's testimony from someone who can drive.
From the PP BBS & Doug Skinner:
Just finished co-driving the "Ulf" mobile this past weekend at a local SCCA 2 day auto-x. My god... what a surgical tool. JP's well developed 914-6 devoured the competition. Made my Kermie machine feel down right sluggish in comparison.
This was my 1st drive in a prepared 914-6. I never believed all the hype about 914-6's being able to drive circles around 911's, but I'm changing my thinking now. The "Ulf" mobile with it's 15x7 and 225 Hoosiers all 4 corners stuck like glue with the warmed over 2.7 providing rocket booster thrust coming out of the corners. The car was blisteringly (that's a real word isn't it?) fast. Sounds like I'm writing for Excellence or something...
I'm still somewhat shocked by how nimble and responsive JP's car was. The car is obviously light, ~2100 lbs or less, which helps a lot. Sticky auto-x tires make a big difference as well. My tires are likely over 4 years old, not so sticky anymore. The recent changes JP made to get rid of the understeer worked like a charm. I never had any problems with the car pushing, but instead was able to get the backend out bigtime coming around the big sweeper at the far end of the course. The brakes were much better than mine too. They never locked up on me once during the weekend; normally I'm fighting this a bit.
All-in-all, an exciting weekend. Thanks to JP for sharing the "Ulf" mobile with me. What a ride!
