I hope to take my FP 914 to the runoffs next year @ Road America.
As I've got a 901 tranny with 904 mainshaft,does anyone have a handle on what the ideal gearing would be for this track.
Also give me your tire diameter and I'll do the conversion to my 23.0" slicks if necessary.
Thanks

Tom,
I can't give you great data, but I ran my '73 2.0 there a few years back and I was at 100 before I left the pits. It is a very fast track. I was maxed out at 3 different spots on the track (probably would have been more if I knew the track better). Matt Romanowski might be able to offer a little more insight to this. - Jay

We were in Jay's stock 901 tranny on 205-50-15 yokos. There were 3 spots were we were maxed out at about 120mph, including pit lane. If you're in the 150 horsepower range, you'll want to gear for 140ish I would guess. You may want to contact John Takahara (PCA National Parade Concour Chair). He's run a lot of laps there and would be able to offer some help. Also, Brad Mayuer (of 914 Limited (309) 694-1797) is close by and could probably offer some help.

Thanks Mattt.
I will contact Brad.Have been doing business with him for years.
Thankfully my runoffs motor puts out a tad more then 150hp(Actual #'s are kinda held close to the vest for obvious reasons).According to some of my competitors,I'll need to see at least 130+ down the straights to be in the ball game.My biggest obstacle will be aero . I'll mostly need to tidy up the air going under the car.Not much else I can do.Also get my weight as close to minimum as possible.
Thanks for your input.

I figured you were north of 150 and I know that you don't want to give away any secrets. The track is very fast. In a stockish 2 liter, we were hitting were only hitting 120 becuase that is all the car had. I would also try to get in touch with John - he's done a lot of time in a 914 there. Brad will probably have contact info for him.
