6.4/392 Cam Swap Drivability Results?

Now that there are quite a few cam swaps out there... With any cam swap I expect general drivability and even mileage to change.

How is the drivability of your car?
How affected is your city and highway mileage?
How is the cam in low speed city driving? Is the responsiveness better at low speeds? How is highway cruising?

While not as aggressive as the Comp VVT cams, the 392 cam is quite a jump from the stock Eagle setup.

Thanks!

Mike

I think the lack of response is because this is mostly answered in the various other 6.4 Cam threads...

I was curious to see if anyone would chime in so we could have a concentrated thread on those questions and answers instead of having to read through 15+ page threads to find the answer.

I to am curious to know if there is any increase, decrease or the same type of MPG in the city/highway as well.

I did the cam swap, heads, and headers at the same time so I may not be a perfect representation of what you are looking for. My driveability was really no different at lower RPM. The big change happened at 4k. The car just went into beast mode. Which doesn't sound good on paper but if you think about it it kind of works out better that way. If you give your car the beans from a stand still you are fighting for traction. So from idle to 4k you are driving pretty much normally without any or much added power. But when you hit the the 4k range, where we play when we race, you feel a 60hp difference.

My MPG only dropped by an average of 1MPG.

I'm finding that increased power at lower RPM is not really that fantastic. I have a E-Force which is a screw type SC and while fun to spin the wheels as I please. I liked how my car was set up NA a little better where it was normal driveability down low and whoah up high. In retrospect maybe I should have went turbo or centri type SC. We'll see how my final tuning goes and if it smooths out some of the dislikes I have about the driveability of the SC.

Two words: excellent driveability

Normally aspirated, stock manifolds, CMR tune (Diablo e-mail tune)

MPG: slight drop city ~ 1.25 from stock
hwy - similar, but haven't taken extended drives to explore further

Custom tune brought out more low end power (over canned 91 CAI tune), mid and extended upper end power output.

The only other 'side effect' is the EVIC shows lower MPG than actual...the tune may throw off how the system calcs, but its no biggie...

>>> is this Exhaust or intake manifold or both? I would like 60 to 80 HP more in the future..

Both - the add'l 12hp from changing the exhaust vs. the cost of parts (I'd favor the clamshell SRT manifolds for mitigating heat in engine bay vs. aftermarket shortys), mid-pipes, labor, its not worth $1k to me for the small gain.

Time and again most of the guys (local shop that works on a lot of Hemis) recommend pull the heads when changing out exhaust...now that's a lot of work, even if doing it yourself.

Paying for someone to that, you can imagine the $$ for that.

My ride was already s/c'd but I did not notice any gas mileage decrease from before aside from flooring it. The main thing I noticed as well as others was the sound idling and driving. Which now sounds more like a muscle car.

Very pleased with the results it also idles well not really lumpy.

Gotcha on the clam shell, but do you change the intake manifold, and replace it with A 6.1 aluminum one from the 6.1?

One could do that - but I'd imagine the composite 5.7 (and now the 6.4) would run cooler compared to the AL manifold of the 6.1. It certainly is more to look at from the aesthetic point of view.

so normally when people do cam swaps and ported heads and clamshell exhaust they stick with the 5.7 composite manifold?
