here is my plans....i will soon be getting hooker LT's and running them back with a true dual.x pipe setup with unknown mufflers, after that i want a cam, i was think lt4 hotcam kit would be good, i have a stock car - mods in sig, and i WILL have the exhaust before i even consider the cam, keep in mind i have an a4 w/2.73, i will be install the 1.6's with the kit as well.....is this right for me????i dont really wanna upgrade gears as it is a daily driver and will be driven to school daily, i would consider the cc305 or 306 if you think it would suit be better
thanks guys

Also any #'s either Dyno or Track times on cars will the lt4 hot cam and stock heads/bottom end would be great as well

 

The hot cam is a very nice cam, I've used it with the 350 and long headers and it was great. I've sold it to a friend who has a 97 Z28 with headers and homemade CAI and he beat LS1s easy.
The kit price is good with cam, springs and 1.6rr.
I'd recomment you change the rear gear to something bigger.

 

what im really asking is, will my 2.73's really hold be back? or will I see as much increase for putting the cam in my stock motor as the peple with lower gear ratio's? i.e. im a ***** and dont wanna spend an arm and a leg for gas, when i wont be driving like hell back and forth to school, but i definetely want the CAM for both funfactor/perf./sound reasons.

 

With an auto and a cam I'd keep the 2.73's you'll see an increase in performance...as for mileage, with the hotcam kit on the highway I doubt you'll see much of a drop off, now in the city that could be different...hopefully someone with experience will let you know about what mileage they get...I'd also like to hear about the 305 and 306 cams as well...just curious...

 

I still wanna know what the hell the 305 and 306 cams are and who makes them? where do you get em?
I see the cc in front them so im guessing comp cams here. how are they different then the hotcams kit? how are they better? what cars are they better suited to?

 

These are the exact questions i want answered!!!!
but from what i know, yes they are made my comp cams, the 305 seems mild, the 306 i believe requires a stall and gears maybe, here is a link, i wish someone of the PRO TECH's here would post.....
here is the CC link

You're correct it's compcams...if memory serves me correctly they have a higher lift and longer duration then does the hotcam...the 306 being the bigger of the two. They're suited to cars with complete exhaust and some significant head work in order to get the most out of them. They develope power to the mid 6000rpm area assuming the rest of the car matches them properly.

 

I'll add a little more...Hotcam kits typically get cars in the 300 and some cases 320rwhp area. The 305 cam seems to be about 20 or so more...the 306 is generally between 365 and 390rwhp...not to say people don't have more or less but from what I've read thats about what I gather.

 

But which cam would be best for me, its for sure a daily driver and rarely raced, except weekends everynow and then, not hardcore though, i will have full exhaust before i get the cam of course, but which is better for a A4 car with 2.73's and few bolt ons?????305 v hotcam?

 

With no headwork??? I'd probably go with the hotcam kit or the 305...the 306 cam is fairly radical and from what i've read you will loose some low end torque so if you're driving it daily you may not like that.

 

the hotcam is :
The duration at lash point in degrees (intake/exhaust) is 279/287; duration at .050" tappet lift (intake/exhaust) is 218/228; and maximum lift with 1.6 rocker ratio (intake/exhaust) is 525/525. Valve lash is zero/zero and lobe centerline is 112 degrees.

the comp cams 305:
The duration at lash point in degrees (intake/exhaust) is 276/290; duration at .050" tappet lift (intake/exhaust) is 220/230; and maximum lift with 1.5 rocker ratio (intake/exhaust) is 510/510. Valve lash is zero/zero and lobe centerline is 114 degrees.

the 306 is:
The duration at lash point in degrees (intake/exhaust) is 290/307; duration at .050" tappet lift (intake/exhaust) is 230/244; and maximum lift with 1.5 rocker ratio (intake/exhaust) is 510/540. Valve lash is zero/zero and lobe centerline is 112 degrees.

ok so now all the info is together. Still a small difference cuz the hotcam is rated at 1.6 RRs instead of the 1.5 CC rates them at

 

So from what I'm hearing it's safe to say that a CC305 will make the most power from a stock-headed car with full exaust?

 

You sure the lift is that high? I thought with stock (1.5) RRs it was good to like a .490 lift and with 1.6 it was like .515....where these's #s from because I'm very curious...i'm getting my heads done as we speak and I'm wondering what lift it's good up to.

And a negative to the hot cam is some people want a bigger cam after going in. Point in case, me. I'm shooting for maybe high 11s on a 100 shot and I don't think I can hit it with a hot cam. NA I'm shooting for like 12.4, but I need to do suspension first

Anyways think of your goals. If you're just trying to get into the high 12s or 300 HP, then the Hot Cam is the right cam for you. On a stock tune I hit 305 with it and AS&M headers, with Bryan at PCmforless I hit 316 horse/330 TQ. It's all in your goals.

 

Comparing the cc305 and hotcam, I think both will perform similar in the 1/4. The 305 is a slightly bigger cam in terms of duration and lift but the hotcam has a smaller lobe seperation anlge which makes it a bit stronger up top.
Price wise the hotcam kit costs around $500, the cc305 with spring kit and rockers could cost around $700.

just pasted it 3 times and used the info from CC to fill in the info so it would be easy to read
