Finally some correlation between how the cam is really used and the profiles....I can see it now..."Oh yeah, well my cam is smaller than that, I just put in a 208 218 on a 117"........

Thanks for the kind words, everyone. I'll be sure to post the dyno results as soon as I return.

I do have a soundclip of the car, but it's on my other PC. I'll post it up a little later tonight.

Im with you on this. Im tired of seeing dyno sheets and requests for dyno sheets, talk of more torque cams and torque down low. None of these guys talk about track times. They talk about valve events and lobe separation. Wheres the track times. Who cares what it dyno's if it cant run at the track. Whats the point. My car never sees under 5800 rpm on the shifts. Why would anyone car about anything under where their car shifts at? Dyno talk has gotten out of hand on this board. People change cams for 15-20 rwtq at 3500 rpm, thats crazy. Im remember when there used to be more talk about racing on this board. No offence to you Josh.

Actually i understand why people want a torquier down low cam. It makes the car faster in the lower RPMs. So when you goos the throttle while driving around you get more of a kick. Its more fun to drive it aggressivly around town, since when most people do this they aren't at WOT.
So, to each his own. As far as my cars power, i only care that it goes real fast when my right foot hits the floor. Anything in between is just to get me from point A to point B.
BTW: Its worse on M6 cars. My 5100 stall provides all the torque i need.

Custom cam here too

GREAT dd cam!

This is true, but those large cams also perform better at the track. Someone leaving at 4k+RPMS does not need low end torque.

No offense taken.

I think you're not seeing any track times because most of the people who make a switch to a cam of this nature are doing so because they don't go to the track very often. I visit the track once or twice a year, so I'm not as concerned with track times as I am a nice, flat torque curve, which can only be confirmed on a dyno.

What works well on the track, where, as you say, the RPMs may never dip below 5800, doesn't work so well on the street. As SUX2BU said, it's just more fun to drive around town with a smaller cam that provides more low and midrange torque than it is with a max-effort grind that makes all of it's power above 4500 RPM.

JaSSon-not everyone gives a huge **** about track times. Low end torque is fun for a daily driver.

Well another thing about the track times. We just don't have a 1/4 track here or close for that matter, unless you count interstate 40, 240 and 26, then we are roll racing. For the most part around where Josh and I live, thats the only time a cam only street car will see racing speeds over 100mph. There just isn't a straight road to be found. So that takes away alot from the T-rex and how much fun it actually is to drive. It just isn't. Like Josh, my car is not or never will be a drag car. Its meant for fun. Thats it.

yeah I dont think my car would last long if everytime I left my garage I was going along at 5800+ rpms Not to mention all the tickets I would get for speed or noise violations. Hell in some areas I might eventually get my *** beat or shot at

where's the DD love? )

What everyone has failed to mention is that I bet you arent giving up much...IF ANY compared to the very large cams even in the higher rpms! It just seems to me the larger cams are not making any higher peak numbers as well.

I think the point of contention is that most of the people looking for more torque are not track rats. They are trying to have a car that is actually FUN for the street. Unless you are like Juan and have a huge *** stalled auto, or an M6 with 4.33/4.56 gears, you need a usable torque curve down low. I know that I am going to do something dramatically different here soon, just havent nailed down what. Big duration+big lift= horse power in an LS1, no ****. I honestly feel like everyone and their shop have their own grind nowadays. Only about 10% of them actually have a clue as to what exact specs will suit someone's needs/anticipated power goals.

Josh, the car sounds sick man! I would love to see some track times with that setup as well. Do you know what numbers someone might expect with that cam and set of Dart 205s or 225s?

Even at the track, where the torque is usefull depends a lot on the supporting mods. An A4 with a 4000 stall doesn't need worry much about 3600 rpm and below. On my old car all power was built around 6800+ rpm shifts.

Now I'm an M6 with a stock clutch and a 10 bolt I do not feel that I have the luxury of 4000 rpm clutch dumps. Mid range torque would help me.

For a lot of people who see the track a few times per year, trading .1 of ET for car that slices through traffic the other 250 work days per year is worth it.

Something else that hasn't been mentioned is the weight of our cars. I know I'd love to have a few more ft/lbs of torque from 2000-4000 since that's where I spend most of my driving time and the fact that my car is a plump 3800lbs with me in it.

I've got a TR224/224 on a 112lsa and love the car. I make 430hp and 400ft lbs of torque but make that peak torque at 4400 rpm. Now if my car was a Z06 'vette and weighed 500lbs less, that would be a different story. I'd probably go with a bigger cam to get more top end out of the car since 400 ftlbs of torque in a 3300lb car feels a lot more powerful than in a 3800lb car.

My ideal combo would be to go with a 402ci ls2 with a very mild cam and make 475hp and 450ft lbs of torque. That would be really fun on the street and still be able to run low 11s at the track with adequite traction.

It's all about meeting your needs and in a heavier car, low end torque is critical.

sounds like you are saying... I just want to leave 20 or so horses on the table.


atleast go with a 226/226 or larger...... trust me.. you will regret it later!
