I didn't make it to SLO 🙁 But I have made progress. WOT issue solved and full stroke at the pedal means 97-98 % open at the throttle plates. Now when I rev the engine the response is really quick and responsive. I've got a Web 86b 105 degree LSA cam in conjunction with a LWFW and the motor likes to rev really quick.
Remote external oil filter is in too and along with the external oil cooler, the oil temp is steady at 180F-ish around town and during normal freeway driving. After 30 minutes of spirited driving the oil temp hangs around 208 degrees. It would be interesting to see where the oil temp settles when ambient temperature rises to mid 80s - 90s in a few months. Though I'm on the coast and so I may have to drive inland to get the hotter weather.
Setting up the Speedster for CHT is next on the list as are four new shocks. The camber compensator still needs to be installed.
I'm going to remove the Fuchs deep six hearts (borrowed from my 912) and replace them with a set of driver condition Porsche 5 1/2" steelies. The steelies are HEAVY. A single steel rim WITHOUT a tire weighs approx 20 lbs where the 6" Fuch rim WITH a 195/65 tire mounted weighs 21 lbs!
I'm going to have to drill 72 lbs (18.1 lbs x 4) worth of holes somewhere to make up for the weight 😄
Paging Doctor @ALB Paging Doctor ALB. We need a surgical consult.
Too bad you've gone to the steelies- 72 lbs is an awful lot of holes to drill!
I don't even know if that much is possible on a car of this size. And yeah, a 15x6" Fuchs weighs just over 12 lbs. Even the cast copies weigh 4-5 lbs less than the same size steel wheel. Sorry, having a bit of a brain fart here- what's a LWFW?
On re-reading your post- you've added 8-10 lb per wheel going from the forged aluminum Fuchs to steel so you're only looking at removing somewhere in the neighborhood of 32- 40 lbs to make up for the wheels, but that will still keep you busy for some time to come (write off spare time for the next 6 months or longer). Generally a 15-20% weight reduction is fairly easy and quite often 30% is possible, but it's a lot more work. Fabricating out of aluminum is the way to go, as al weighs about 40% of steel. That's why the Speedster recently for sale (2? 3? months ago?) with the aluminum sub frame was so cool- 120? 150? lbs lighter to start!
At Carlisle @edsnova suggested I start a thread showing the weight reduction I've achieved with various parts. It may be time- stay tuned Ed, for "Some Of The Holes I Have Drilled" coming soon!
Yoda out.
