swapping engines someday, Whats the weight difference Options

[Jetsetsurfshop]

Hey race fans,
Sometime in the future I plan on running a 2.7 six over my four banger. Anyone have any idea about where my weight will be after the -6? I'm I looking at 50lbs? 100lbs? More??
I could drop some weight from the car still. Want to get that HP to weight just right!!
Theres a large group in NASA (ST4) I think I could fit into perfectly If I get the math correct. (IMG:style_emoticons/default/beer.gif)

175lbs +\- for a 2.0-2.7
200 +\- for a 3.0-3.2
225 - 3.6

I always tell people its an additional 150lbs.
but I think with all of the accessories... tank, lines... these numbers are good too

Also, the early Sandcast 2.0 is heavy.. I moved to a 7R case to drop more weight and remain 2.0


The race shop I use out here... (specializes in 914's) His advice is that the 4 cylinders can be built faster and lighter until about 2.5L
then the 6's start to make more sense

I just saw a dyno printout for a 2.0 sandcast six that was making 272hp at the crank. He uses it in his ‘65 race car. He said the mag cases would not last for him. They are all too old.

That I would totally agree with
the machinist tried to talk me out of the switch
explained that the mag will not hold its shape and will need full machining, including line bore at each rebuild. (the sand cast is much stronger and needs thousands less in rebuild machining)

That is amazing HP for a 2.0
how did he do that?
still an actual 2.0?

Even with a lot of expensive machining, the problem is the mag is getting brittle and starts to come apart. Age is not kind. We have mag parts that should be worth thousands, like 911S oil consoles, minilite wheels and engine cases but they are too corroded to use. I'm sure part of it is condition dependent (east coast) but mag is so reactive and it will eventually age out before aluminum. Luckily, Catorce and guys like him are bringing new product to the game.

Still an actual 2.0 but for the guys who can afford to race '65-911's, its just money.

Still pretty amazing
anything over 110hp/L is pretty amazing

220, 230 was about the ceiling from what I had heard
that is darn good output!
