All that overlap will help the peak power stay broad and flat. I don't feel they have such nice street manners though..........
Wizeass: I'm suprised the single plane didn't show a significant difference in the overall power curve. Irrespective of the net numbers I would expect a difference in the shape of the curve between a plastic intake and a single plane. (Although I'm not sure if you did a back to back comparison).
Other than dialing in for peak power output, getting the AFR right is mainly important when in the car. As is the case with carbs which usually require some adjustment from dyno to car. The fueling sensitivity is mostly related to the relative load on the crank at any given instant.
Some engine mangement systems will fuel and time each cylinder in pretty short order but they cost some big $'s.

Gotcha!
When do you expect to get the new cam installed and running?

With my 232/238 .599/.601 113lsa and 110 centerline. Dyno 470rwhp and 445rwtq. Peaked at 5300 rpms for both and really fell of hard at 6400 rpms. I have a couple of bigger cams to try, but very reluctant to try? This set up runs awesome for daily driving, with idle set at 875 rpms, with crisp response. Low end power is very good with my 60' at 1.60 1/4 mile of 11.80's. I did find that the L92/L76 setup for me does like as much timing as possible. I did keep my compression at 10.2:1 and run 36 degrees of timing.

nice, I have been looking for truck referances. Seems like the cam selection will be very critical in getting a heave truck going. If your power comes in @ 2000 would a different stall help any??

For example a local Dynojet rated our buddies 427 at 524rwhp, Rick's dynoed it close to 560rwhp. Big discrepency there...

Forget Rick's dyno results since his DynaPack is known for dynoing higher than the local DynoJets. If you are basing this on numbers alone then that would not be impressive at all.

the problem i have with that is this... the before dyno looked about right, and it showed a big increease from the before to after.
seems that his results are real to me.

If you like what he is selling then buy it, but don't say that I didn't warn you that it is just the same as everyone else is selling. My comparison between dynos was to show that he hasn't exactly nailed it, it just looks bigger on his Dynapak.
That is what is up with that.

His results were qualified by the big numbers he is making; and I was pointing out his results are higher on his dyno than all of the Dynojets in this area. Thus his higher numbers... aren't higher...

My point was just that the numbers arent really the iussue, what i would look at is the difference in the before and after numbers.
you misunderstood me. I wasnt calling u out. I was saying "whats up with that" as far as his dyno putting out such high numbers? MAssaging results in not the most honest thing i have ever heard of.

Actually despite my personal problems with Rick, I just think it is the nature of the type of dyno he is using. Rick will tell you he has it calibrated to read like a Dynojet, but there are quite a few of us that have done literal back to back dyno sessions to show his results are typically higher. I don't think he is actually trying to con anyone (at least I hope not); but that is just the nature of the Dynapack... Sort of like the difference between a Dynojet and a Mustang dyno...
Regardless the gains would be better measured baseline to end result, but even then it seems the Dynapack registers a larger variance the higher the HP goes. Most dynos there is a ~5rwhp variance that is considered normal, I just think it gets higher on the DP the higher the rwhp goes. IE the end results will seem larger as the variance has gotten larger... *shrug*
Sorry for the misunderstanding.

It really is a shame that things like this happen.. i.e. some people inflatting numbers or being dishonest, because it F's things up for everyne else.
I mean, Rick may be on to a top notch combo and got the tune down, but is getting doubted due to shady people in the past putting doubt in peoples minds.
I dont know Rick, ron, mike, etc. I havent dealt with any shops, Vengeance or others. So i cant and wont speak on anyones behalf or poop on anyones results. But it sucks that this happens, cause it makes it really hard for people like me (who dont have much experience or knowledge in this game) to know where to go to get work done or who to trust.
How do u know who has got your best intereest and performance at heart, or who is just trying to sell you something?? (Rhetorical question)
