all the more power to ya then-been up since 4 this am-drove 2hrs to track, raced 3 classes,then drove home-and took care of 3 of my customers ac's-btw-not only did i fill my van ,buddys truck-paid all our entry fees and tolls-not bad for a guy who can't spell or use grammar-maybe i should have wrote a canned tune for a tuner that causes droaning with aftermarket cai's -then turnaround and sell the same customer a custom tune to rid the problem i created-then maybe stealth would believe me-lol

 

 

All I'm saying is, with true duals you loose some torque down low. You move the power-band w/that much flow. If your working it, torque is your best friend, just above idle on it's way up to cruising speeds.

In your case openclass, I would data log if you haven't already. Send that in to Troyer and have your tune tweaked - for your mods.

 

I wish I could post the data for you, especially since you seem to be taking this a little personal, especially for a little debate. Irregardless, my computer just recently crashed but on the other hand I really don't care if you believe "us" or not. "Us" is Phil and myself for clarification. I won't lose any sleep over it and I'm sure Phil won't either. Here's something else to consider is that the 4.6L 3V in my S197 does not lose or gain any power with a muffler swap or the loss of mufflers. The stock pipe size is 2.5" with a factory H Pipe. How do you explain that?

 

I'm not taking it personal - I've read about it on this site and have increased flow myself in my truck to the point of very noticeable torque loss. You can tell right away from the line. You think I should back down because you have a hard time with the facts ?

- Mann, you should give it up. The S197 3V is bad a$$ little Mustang motor , a totally different animal/ different setup entirely. It's not set up to tow/work. That tells me something - can't believe you even compared. The "H" pipe on that car is for power ,sound and this also keeps it from resonating. It has the cams, intake and compression to warrant more flow.

Your not Phil, he's quite a bit more respectable and has said there could be a loss. So minimal , that he didn't notice. I can see that. - Your out-classed there

You can't compare car motors with truck motors.

BTW - Yes, I know your talking about the 4six 3 valve.

 

Hey guys

I haven't been around in a while but i see everyone is still fighting over true duel exhaust systems

 

- What's up Kev

Oh , this this happens allot over here ? I'm sitten in a freakin hotel room out of state, board as hell... Have to find something to do

I am surprised there's only two going against the grain. I'll dig up Shifty's Dyno run - to end this.

 

I think you are getting a little personal about it like this directly effects you in some way. Anyways, I don't have a problem with facts at all, I have a problem without facts. When we tested it we did a few part throttle pulls at 15% throttle, 30% throttle, and 50% throttle, as well as a few WOT runs. I can tell you that on my truck, with my set-up, I did not lose any power or tq any where. I've never said it'd be the same on every set-up. Remember when I told you to not think in absolutes? I'm saying you could very well loose torque, there are a LOT of factors to effect something like this. To keep argueing about this is quite pointless since you're not going to change my opinion and I'm not going to change your opinion. So with that said, I'll bow out.

 

Hey, shut up

Joking.

 

Dyno from Feb 1st. K&N 77. E-fan pacesetter shorties no cats dynomax super turbos


This will work, as an example I guess. From what you can see; - Peak torque is @ 4600 RPM's compared to stock; - Was @ 4000 RPM's. Look what happened to the somewhat stock 4.6L @ 4000 w/more flow. See there..? Max torque was pushed forward 600 RPM's, which supports the only fact I was trying to make.

So power was pushed back, torque went forward creating loss down low. It should be the opposite; - Torque should push you into your max HP range, in order to work together.

1997 4.6 STOCK #'s

Hp -------220 @ 4750 RPM

Torque---265 @ 4000 RPM

Those are FWHP #'s above.

 

Yea, Perfect Timing

 

i said i was done with this topic-but you failed to mention he ran 3" duals on a stock 4.6

 

Just been informed that user ThumperMX113 has done this sort of thing before. He's used the "My computer crashed" story before and pushed for facts without providing any himself.

When proved wrong - Runs away like coward

Hey, know big deal guy, I don't think your coward.

Pansy fits much better

 

I don't believe he did on this set up. I think he went to 3" after his Longtube install. This was w/shorties before all that happened. I could be wrong - not absolutely sure.

 

Are you kidding me? This is funny, very funny. I wasn't proved wrong. I'm just bowing out because I'm not going to nor is anyone going to change your opinion about this. I have had my computer crash before but I didn't even think I mentioned it before. I could be wrong though, you have a link to it? Anyways, check out the General Discusion forum, you'll see I posted about it a week or two ago. I'll be getting my Dell XPS 630 tomorrow because of a lightning strike that caused my motherboard and hard drive to go out. As far as the name calling goes go pound sand, it really shows how mature you are.
