I've got a CC306 but I've been talking with someone that says that I will lose lots of low end power.

whats with this???


I should add that I will be going with heads next year.

 

The 306 is going to be better top end the bottom. I would look at launching the car from 2800 to 3000 RPM. The idle will be a little lopy, so be prepared for that. The 306 is a pretty good cam, you might want to do some work to the heads you have.

 

ok, its not going ot be a dog off the line is it? and I'm not going ot have to rev the hell out of it jsut to drive it on the street in trafic and stuff?

how far down the dyno graph would the 306 be compaired to a stock cam with stock heads?



man I really cant wait for heads, but funds dont allow them this year.

 

with stock heads you will gain a bunch of low end grunt. but port them and you will loose some but not much. it is better to loose some low end power since you can launch much better.

 

mainly just launch a little higher, like 2800 - 3000, you dont have to be stomping on it, just a lil higher rev. im sure you could let go lower, but i dont thing it would react well under 2500. if i remember correctly the 306 powerband is like 1800-5500, so its feasable to let it out at 1800, but id still go higher.

 

Rev that sumbitch to 7k. 306 is all about top end power. 305 is more mid-range to top end.

 

dude, for a cam with a power band from 1800 to 5800, the revs dont have to be that high. the 306 is an aggresive cam, that will produce good curves all the way to peak.

 

The 306 will make power past 5800, dude.

 

from an idle and daily driving am I going ot have to rev it high jsut to normal drive?

 

if you cant afford heads, look into a set of gears to help compensate for the loss of lowend
and i dont think you would need to "rev it high" for driving in traffic, you can putt around just like normal but you'll notice the car will feel a little more sluggish in the lower rpm range say 2000rpm's and lower prolly
but when you go WOT it'll all seem worth it, cuz that cam pulls very nicely

 

You will be fine daily driving. What they mean by reving higher while racing is because the 306 makes better power at top end not bottom end.

 

I have never heard of a aftermarket heads/cam LT1 making less low end torque than a stock heads/cam LT1 if it was running correctly.

 

I will reiterate....what i meant was sluggish under 2000rpm's in comparison to the cams powerband above 3000 where it really starts to make power
but anyway it'll be driveable in traffic

 

Everything is getting blowed out of proportion! It will make more than stock, but the chosen cam is not the best for low-end power. Driving around will be fine, reving will not be necessary from a stop. It's not like its gonna be a dog off the get go, the 306 just doesn't shine down low. This cam will not make your car less powerful off the line like an LS1

 

I agree, I was just pointing out that if he has a stock cam now, he will still enjoy the benefits of tons more low end torque.
