I don't see that one happening anytime soon- Being a professional asshole is a delightful position to have!

asshole or not, I agree. I have seen some "car of the year" awards that just didnt make sense...but I am sure they made dollars for teh magazine in wich they were displayed. I.E. H-1 Hummer? SUV of teh year? Have you ever looked under that thing? its a blazer with a live axle rear. I think Le Car was car of teh year. so was teh Alliance

Money talks.

are they good in a daily driver or is stock better for commuter cars?

No good in a daily car, or even a weekender. They're WAY loud, and can often completely dominate the engine note. Depending on the exact gears, you either get an irritating ringing sound, or a loud whine that often sounds like you're driving a executive jet or something.

Honda used them in some street motorcycles, but they developed a clever "scissor" arrangment of two gears side-by-side, sprung loaded to take up the lash between teeth. This quiets them down some w/o the side-loading cause by helical gears.

I, run strait cuts, daily driver, 1,000 - 1,500 miles a week. Loud? Hell Yes.

Why? I'am running alot of spring pressure, (SBC springs), the cam, lifters and springs are a proven combination, one thing about the springs, they will never let the valves float, miss shift or otherwise. This combo is what I'll use for my .600" lift cam. (IMG:http://www.914world.com/bbs2/html/emoticons/happy11.gif)

Britain, what cam you running, springs and what bore & stroke? And I see you had your crank dowled.

The motor is 78 stroke and 98 bore, making is a 2353cc. It is running a custom grind cam from Jake that was designed with the flow rates, turbo charging, Pauter rockers, etc. in mind. I am not sure of the specific specs, but I know that it is a split duration between intake and exhaust.

I guess he'll just stab it and go! I don't know what advance/retard washers he used when it was assembled..... I'd personally run this cam straight up as long as it degreed correctly.

Most DIY guys just don't understand degreeing in a cam- that can really bite you in the ass though!

BTW- I have seen one more web cam be out like the one you got. I put every cam in the cam doctor and found one on a 114 L/C that should have been on a 108- it was the cam for the Super 2 Liter- it degreed in perfectly after I had them repair the issue.

Carefull!  914 was MotorTrend's  1970 "Import Car of the Year"

[QUOTE=]Even the straight cuts that I sell are kinda questionable.. The best set in the planet cost 450.00 at my cost and even they are crappy and need work...

Unless your engine HAS to make 100HP+ PER LITER stick with the helical gears... Hell my 3 liter don't even have them, and don't need them...


Yet another product dumped on the market from pure advertising! A solution for a problem that doesn't exist.

Just cause somebody makes it, and somebody else sells it, and some PR guy that's never had a wrench in his hand in his life comes up with a BS rap that sounds plauseable, IT STILL DOESN'T MAKE IT A GOTTA HAVE PIECE!

I installed that cam using the zero degree washers. I have a conceptual understanding of degree'ing the cam, but I have never had any experience playing with it.

Its not just a Web problem. I think it is me. Everytime I do some custom stuff I have to keep going back and forth to get the manufacture to get it right. I must be the only person on the planet that won't put my name and reputation on garbage.

Most people can get by with just pokin' the cam in and hopin' it is right. You do what lets you sleep at night.

Nope two of us!

I get lucky a lot of times... I honestly think that sometimes when guys off the street order somet things they get "Whatever"....

Web knows that I'm gonna throw every cam on the Doctor and degree them all in when I build an engine so *maybe* things are more checked out... Also I only buy TWO cams off their shelf- all the rest are custom so they have to be made...

Luck sometimes runs out- Like it has for me with this FP engine... Its together and rewady for the dyno in the morning, but EVERY part of it has haunted me.... over 125 hours in the past 7 solid days of fiddling with it.........

Its gonna be another all nighter just to get it up on the dyno and hook the logger to it and crank for oil pressure...

I know this thread is over a decade old .... back then peeps thought available straight cut cam gears were not good quality. I figured I would ask if this 'situation' has changed since then.

Is anyone running straight cut cam gears now?

This vid shows a VW type 4 with straight cut gears. I think it sounds pretty good (IMG:style_emoticons/default/sunglasses.gif)

^ I like it, almost has a /6 motor sound. I think those long chains on the /6 make up some of the "noise" that we love.

I miss my '90 VFR so tremendously. Stock headers with a slip on. Revving up through 5,000 RPM and beyond -- words fail me...

+ another on the vfr's. mine was an '87, dark blue with a yoshi slip-on. best sounding bike motor ever, in my opinion. nice power characteristics too, torque like a v-twin and top end like an in-line 4.

now back to our regularly scheduled programming...
