I assume you mean the boost actuator at the back of the S\C?

I set mine before putting the S\C back on placing the bar right on the stopper but I will tinker with it when I get my tune back from usahooters. I know it can net some gains if not adjusted correctly. I wonder if after a port some of us are getting it messed up a little???

BTW great numbers,

 

Thats some nice numbers bro. Congrats and a thumbs up on your work.

 

Mike had his truck dyno tuned by Jim last June when I did. So his tune hasn't changed at all. Pulled the blower off, ported it, and reinstalled it. In all fairness he did add 2lbs of boost upgrading from a 4 to a 6lb lower.

His dyno was more to ck the a/f level to he can safely drive it untill Jim can retune it in May. But just changing the from the 4 to the 6 and porting the blower showed and nice increase, and by retuning it with the new mods, those number are going to rise. Those numbers aren't going to come out of 2lbs of boost so it's obvious the port had a lot to do with it, and once it's retuned, we'll see the full extent of it.

I'm having my truck dyno'd hopefully next week, and the only thing i've changed is JUST the ported blower, so I will have a true before and after. We'll see where my a/f stands and if i need to get retuned.

 

Someday, maybe someone with more money than I will get an Apten blower AND WASPII(III)(IV)(ETC) and do a same day comparison. Without that, all these results are meaningless when trying to judge who does what better.

No flames here, just looking for some of the "scientific method" to be applied.

i cant wait to get my blower back from you. Be nice to have the latest and greatest

 

That's often in short supply in go-fast circles.

As part of my investigatory work for the Vortech v. ATI lawsuit, I interviewed scores of speed shop/dyno operators looking for documented, controlled before-and-after data. Amazingly, only a tiny fraction of the people buying $$$$ speed goodies are willing to pay $50 for a couple of baseline runs.

So, despite the rise in recent years of what Jim Bell calls "the universal lie detector" (the chassis dyno), customer apathy allows speed vendors to continue to lie to us about power gains. Maybe people just have an "ignorance is bliss" attitude. Most of the customers only want "after" runs to be able to compare organ size with their friends.

I'm baffled.

 

The tune was just changed for the ftvb....he had to re- do the transmission settings.

 

I also bet if anyone took their truck and Dyno'd it 5 times on 5 diff days "with the identical Mods", they'd get 5 diff results. A dyno only gives you a rough idea of what’s going on AT THAT SECOND.
Something simply to use as a reference point. And how you set up perfect A/F's on a truck not moving is something I'll NEVER UNDERSTAND. This is part of the reason I could give a rats a$$ about Dyno-ing mine, or getting a dyno tune for that matter.
God knows enough trucks blow up after a Dyno tune, so what did it prove ?????

I have seen enough Dyno's of a Ported Eaton, (Wasp and or Apten) to know it carry's power to a MUCH HIGHER RPM, and yes even adds HP + Torque to boot. That is thee one and only reason this Mod interested me, that is also thee one and only reason I got it And that is exactly what it did, I don't need a Dyno to prove it either.

If someone wants to be innovative, invent something that monitors A/F Timing and Cylinder Pressure WHILE YOUR DRIVING,
and a chip and or computer to make constant changes to keep you at optimal performance AND WITHIN A SAFE OPERATING RANGE.
Oh but it doesn't add HP, wonder if anyone will buy it ????


The point here is, ANYONE that has a ported Eaton, Wasp, Apten, REM, Tommy's, Whoever’s ? KNOWS if it made a diff, OR NOT, (I still have not found 1 that has not).

Tim, it's the ignorance of some people around here just not willing to except the fact that just maybe someone else’s Port Job,
Mod, Tune, whatever is as good or better than their's.
And then have to do everything in their power to talk schitt about everyone else's, while meanwhile you find out when they did their before and after Dyno comparisons, there were so many variations changes, secrete mods, diff tunes/chips, etc, that you cant possibaly believe the results, """YET""" everyone accepts that Dyno as gold.

OH PLEASE

Wes's Dyno shows exactly what each and everyone of us with these Ported Eatons already know. It carry's power AND MORE OF IT up into a higher RPM range where we were formally dropping off BIG TIME. That is why I bought mine, that is what it did. There really is nothing to argue here except who has a prettier hole

 

.....





thats alot of thought at 5 a.m. here....i can barely hold my eyes open.

 

Schitt, I've been up a good 3 hours already




Morning Wes

 

i had to work all night...good nite.:santa:

 

Dynojets do not have the ability to simulate actual, over-the-road conditions, but most eddy current dynos DO (although, because they are more expensive, they are a small minority). The only real difference between those dynos and the real world is simulating airflow across the truck.

Dynojets do not need continuous calibration like the others. They are too simple. Take a big drum, spin it under acceleration, and measure the power it took. They are very repeatable and, given atmospheric corrections (automatically done by the software), produce consistent results under varying conditions/different days.

But, as you point out, the problem is with the owners and operators, not the machines. Dynojet claims that all of their dynos will measure within 1% of each other. Considering how simple they are, that is not hard to believe. But I still do not trust a comparision of two different dynos/dyno operators.

The best measure of real-wheel HP continues to be 1/4 mile trap speeds. But the rear-wheel dyno is a close second. The butt dyno doesn't even rank.

I certainly did not mean to imply that I favor anyone's port job/chip/mods over anyone else's. I just hate that people usually don't take the time/spend the money to gather scientifically valuable data on the mods.

And I cannot for the life of me understand why otherwise responsible vendors do not present solid, reliable performance data for every part that they sell.

 

I agree with you 100% Tim and I know you DID NOT imply that,
sorry if it sounded that way, I didn't mean it to. We all know who constantly talks schitt about certain mods from certain people.

"I agree we see too many variations to usually get a honest comparison". And thanks for expalining the diff Dyno's. But I see enough in Wes's to see what I already know, a Ported Eaton produces more power and for a longer period of time, right up into the high RPM's.

As for A/F someday you'll have to explain that to me.
How is a truck strapped down, spinning it's wheels on drums,
in a hot shop, at WOT, suppose to give you a true A/F when it aint moving or taken in the air LIKE IT WILL BE WHEN IT'S MOVING ???? Especially for those like me who have forced air being feed from more than one inlet ????

 

hehehehee, Rob your on the soap box son. LOL

I agree with some of that stuff you said. I always tune my L on the street with the wide band and my dyno is the track.

 

I know Jim was saying how ram air kits will mask dyno numbers.......then i say him prove it. I think there was a 9 hp difference when removing the box and putting an open k&n on there.

You would be far better off to simply remove it for dynoing.

Also, if you let your truck cool down before and in between dyno pulls, i don't believe that engine is gonna get hot fast enough to be able to maintain high heat which would throw the numbers off. I mean the pull lasts what.....10-15 seconds???
