sad to see you go
they arent gone yet, they are currently trying to get an employee buyout
i woudnt call them dead yet
comp > *
damn... I bought a comp cam though
i prefer comp cams also
except for the shitty ass thumpr cams (who the fuck had that idea) and the XE line tends to flat lobe a lot
they're closing one factory. they aren't leaving leaving.
They are supposed to be back open on Monday.
Crane > Comp any day of the week. PERIOD.
It was confirmed that they will be reopening after restructuring. Besides, even if you don't prefer Crane cams it would be bad news. Crane is the largest supplier of cores for cams, a lot of the other manufacturers simply grind them.
Less competitors = higher prices. Just a few years before I was looking to do a nice 5.0 build for my Mazda pickup. I imagine the demand for aftermarket stuff like that is going to drop.
Whats the difference if you have a custom ground cam vs. a brand new one? They put them through a cam Dr. and they still check out fine... I bought a used Crane cam and had it reground to what I wanted
i dont really understand your question?
there is still a ton of cam manufactures, lunati, comp cam, isky, edelbrock, crower, gm, etc.
I was just talking in general. As demand drops the aftermarket market will dwindle.
maybe for the less popular engines
isky has like a million different cam grinds, anything crane offered you can get from isky.
in tests the thumpr cam had the most torque out of their 5 most popular cams, and only down 10 hp @ the top.
sounds like a good cam to me.
thumpr cams are poser cams
tight lsa, and longer exhaust duration make the idle very "radical" even though they sound like complete ass/shit
anyways, they have very low lift, once you get a set of flowing heads on the car, that cam is useless
So basically they are a huge lope/low vacuum idle cams so anyone that knows how to build an engine will quickly over power it and then they'll die trying to come to a stop when they don't have any vacuum assist brakes?
im not really sure what kind of vacuum the cam gives, but they are basically a low lift, low intake, high exhaust duration cam
like i said, the reason why it sounds so radical is because of the tight LSA, and the long exhaust duration
try listening to some sound clips on youtube, IMO they sound like shit, its just a street cam made to sound like a race cam
i have a 230 duration cam in a 302, and that thing pulled around 10-11" of vacuum, i cant imagine a thumpr cam in the same situation giving any less
i would expect between 14" and 15".. but really.. i have no idea
Good point, My dad's 383 had a huge ass cam in it and had like 4" of vacuum. Totally spaced the small cam part of it. If you are going to spend the money for a cam, why not actually get a big ass cam that will lope but actually perform at the same time as well. They are basically banking on retards that don't know what they I doing I guess
probably.. but 4" of vacuum?
if so that must be a huge ass cam
but there is way more to it then just putting a big cam in
for instance, if you have the stock converter, you cant go with a huge cam because you are gonna have low torque at idle, and its gonna want to stall out when trying to move (autos only) so replacing the cam has to have the powerband starting in the low rpm range, then comes rear end gears.. so even if a cam fits your engine description, you might not be able to use it unless you want to drop the trans and change the rear end gears
if you have the stock gears/converter you most likely have the stock heads, which flow like shit.. putting a huge cam in a stock head wont do you any good (it will give you more power, but you wont get nearly as much out of the engine)
but you're right, they are making money off of the people who want a radical idle but dont want to do any other engne/drivetrain mods
here is a thumpr cam: http://www.youtube.com/watch?v=VM3C5aid00k
i dont know why, but the idle just sounds crappy.. since its not really a great cam, everyone has the idle turned down low and it seems way too lopy for the idle they are running at
heres what a REAL lopy cam sounds like: http://www.youtube.com/watch?v=llisRAS9sYM&feature=related
edit* and just for the hell of it, heres the cam im putting in my 400 sbc http://www.youtube.com/watch?v=vb2IwqmXsCA&feature=channel_page
edit2* another example, i have a 230 duration cam (280h cc) and its radical as hell in a little 302.. after i took the trans off and checked the gears. i have what im assuming is a stock torque converter, and 2.73 gears in the rear
the car is a dog at idle/low rpms when i move it, i couldnt give it any gas or it would want to stall out, so i had to let off of the brake and just move it that way.. it was hard as hell getting it back in the garage because i have a little bump that separates the garage floor and driveway and i could barely get over it without working the gas perfectly, didnt even have enough power to spin the tires from idle because it would just stall while trying to brake torque it
All I was staying was who cares the Crane is one of the largest cam core suppliers... take your cam else where and get it reground if you can.
Why is it that American v8's have to sound like a rough pile of shit to make a lot of power?
The cams profile is for higher RPMs not the lower RPM... How often do you leave the starting like at 1.2k? I leave at 5200 and stay between that and 7500... why do I care what my car sounds or drives like at anything lower then that?
he is a troll just ignore him
I'm a troll because I like the sound of a healthy engine that makes just as much power and doesn't idle rough more than this: http://www.youtube.com/watch?v=llisRAS9sYM&feature=related
