Sorry Wilson, I could have phrased that much better. My apologies.  Was just curious as to the "why", saw you've been co-driving lately, couldn't find much driving.

'Cause I've got a sweet ride with Charles Sherrill, and can routinely put him on the podium. Otherwise I would be spending more time behind the wheel mid-pack but having fun in one of the Bimmers. As it is, the E30s' co-owners have benefitted because of this. I'm bench-building an E36 Compact which will be the replacement for the E30s. Saw that the Quaife 5 speed sequential was about $5400 from VAC (and everybody knows VAC is $$$$). Also looking into the M52 2.8 liter, which can be built cheaply (relative to the S50/52 or S14) to over 200 hp using M50 intake and S52 cams. Could be a fun combination. Kind of inspired by the CM3C as well as the current fiesta (wrong driven wheels). http://www.compactm3cup.nl/downloads/reglement12.pdf. That's why. Nothing sinister. Just for shits and giggles, which is what this sport is about for most of the folks that I know. "Talk about drugs.

When you bench build yourself into needing a the CM3C body kit...we might have molds to run off more kits down at the shop.

Two things really. First off, http://www.eliteracingtransmissions.com/index.php?il-series are reasonably priced from what I've seen. Reliability? Fawk, I dunno. Just haven't seen them mentioned so thought I would.
Second, a question really... how much time are they worth, really? Like, assume we're building something for Group 2; call it a 240hp Duratec for sake of an example, so there's not going to be turbo toarks everywhere in the powerband - all this gearbox monkeying around gets more desirable then, no? Looked up how some of those Fiesta R2 thingies placed in a few rallies, and they seem to do good; strikes me that the things they have over most of the US cars is expensive gearboxes (close ratio and sequential) expensive struts, and are factory built. How much of them doing well is the boxes, compared to the other two things or the nuts behind the wheel? Honest questions, not trying to start shit. 
Hoyeah, and not sure what the CZ box John is talking about is, but I saw an Aussie sequential shifter dealie that bolts on the sides of shit like T10s; strikes me that the "slots cut in discs" idea is probably how that works. Edited 1 time(s). Last edit at 04/10/2012 04:31PM by mekilljoydammit. |

Well don't feel bad, Mike Quaiffe Jr, who took over from Dad didn't know either but my description of "Take the drum and snip it like dis, then hammer da fawker flat" He got that. I saw "the flinch" of recognition.... The advantage is it is extremely small, only bout this thick, very strong and very easy to machine compared with the shift drum which is whatever in diameter and as wide as the shafts in the box. That was pre Google images so I couldn't just grab a piccie like (snap) and show him what was already a 20 year old design then. But here it is: 
You are familiar with shift drum, yes/no? The funny thing is that bike stuff is and has always been easily 20 to 30 years of car stuff and race bike stuff is just flat good. So if you spent 15 or 20 years seriously involved in motorsports, its sort of hard to take fretting about little piddly shit that may be some imagines 1-2% advantage---it's still shit compared to what normal; working class human beings can just walk out and buy (of course the problem with bikes we don't see too often in cars: you have to be pretty damn good to get the last 20% out of the bike and if you can get the last 1-3%, you're making a good living...sitting on your but in a warmed over_________ isn't quite the same degree of difficulty) Note that those 4 speed CZ and for that matter the 4 speed Maico boxes would shift nicely under full gas, just wiggle your toe. About a 1* back cut on the dogs (back cut varied on stuff from as far as I could measure 0 degree to maybe 7 degrees, and 3-5 degree being common. 0-1* flat shift 3* fullthrottle but fan clutch 5-7* back off the gas---great for streetbike, old geezers etc John Vanlandingham Sleezattle, WA, USA Vive le Prole-le-ralliat www.rallyrace.net/jvab CALL +1 206 431-9696 Remember!
