Title: What Would You Do With A 84mm
Post by: steveo_32 on January 19, 2005, 12:20:47 AM: So lets say you had a 84mm crank and rods. What combo would you use for street and the rare run on the track....
Lets hear idea's right down to bearing preferences and head-carb combo!

I know a few locals that have very nice 2332s that see the street/track with consisitant 12's and an 11 :P

If it's going to be mostly street use with a little track time consider 90.5 P&C with 8-8.5;1 comp a Engle 120 or better a K8 with 1.4;1 rockers. If you want more power go 94mm and 9.-9.2;1comp and the k8 or web 86b (same profile).
Heads will make a world of difference so buy a nice set (ported by Darren)

Post by: nivag on January 19, 2005, 02:01:47 PM: I agree with Geoff, but go 94mm not 90.5 (will cool just as well and give you more hp for no more expense) and run low compression (8-8.5) with a mild cam.

PS: I take back what I said. I think you should donate the crank to me!

Post by: steveo_32 on January 21, 2005, 12:11:58 AM: Very cool info! Thanks guys. I decided to use the 84 crank in a 1200 case to save room with a engle 100 and my own gears out of bakalite with quad 30 picts!! And a dual point coversion from a chevy!

Post by: Chad M on January 26, 2005, 08:50:32 PM: Just out of curiousity, how much estimated hp would the 84mmX94mm, W120, 044's w/ light P&P, 8.5-1 cr, 44idf's and a 1 5/8 exhaust make?
Would there be a better cam choice for a purely street driven bug? This car won't see a drag strip and it will likely be driven on the highway for a couple of hours at a time. I'm thinking really big stock motor here. Thanks.

Sounds more like an oxymoron......

Would it not make more sense to just maintain a good 1600 and get a decent tranny?

Post by: Chad M on January 26, 2005, 09:06:01 PM: Come on man. You can only drive a 1600 for so many years. I'm tired of building 1600's!!!!! Have you ever droned across the prairies in a 1600 bug? Damn, sooner or later you're going to want to pass somebody, keep up the traffic on highway 2 etc... I want to build a very well mannered, stout engine that I can still use my stock gearbox with.
