Currently at work and can`t check my home email, but what I also noticed is that at a good throttle, not full throttle that at 3 grand on the rpm`s the boost level start to drop. Is this normal, i`m not giving it a full go but at a good amount about 3/4 the boost drops when the rpm`s hit 3 grand. I found my dyno sheet, it reads 315 total rwhp with 405 torque. It made peak hp between 4445 and 4723 rpm, and total torque at 3057 rpm on a Mustang dnyamometer. Also something about filter mode FIR and filter value at 11. Because of the new motor and the old superchip that was in it before the dyno may have caused the old motor to blow, he didn`t want to run a base line on it at frist in fear of detanation. I asked if they dyno other lightnings and he said yeah, and that`s a normal rating on there dyno.

 

Where is this I/C pump located at, and which resorvoir i`m to look at.

 

I've never heard of a "helix bore spacer" placed between the throttle body and plenum on a Lightning. I don't know what the advantage would be to inducing "turbulence" there. I'd remove it.

PS: As for those "tornado" devices - there never has been any scientific "evidence" presented that indicates that they do what they're "claimed" to do.

 

When you open the hood the IC resorvoir is to your left and the pump it's self is under the truck attached to a hose. Pretty easy to find up front.

 

Thanks I know just where it is now, and hope that it is the problem behind my low dyno readings.

 

The Helix bore spacer works by taking the cool rough air coming in ,and spin it to a smooth air charge into the intake, plus adding a 1 inche spacer between the throttle body and the intake. They said it would give around 5-10hp, and 20 ftlbs of torque added, plus better fuel milage. I think I got it from Godfathers performance 3 years ago.

 

Don't you think that if adding something so simple to an engine added 5-10 HP, that the manufactures would do it?

 

Checked the I/C pump today working fine, so what else could it be. Bad dyno reading? bad dyno? or bad tuner? I like to think that the truck runs just as good as it did stock by driving it, it shift hard enough to feel like it`s knocking you into the back of the truck. Whats the difference between a Mustang Dynameter dyno then others? This guy insured that there dyno was the best there is in testing and tuning. It`s the big one that you drive on like a lift ,raise it up so you can walk under it,and then they back the vehicle on top the dyno.

 

Not realy Meangene, if that was true my trcuk would have came with the cold air kit, long tube headers, free flow exhaust, and single blade throttle body from the manufacture.

 

Kane: I think if you do some research, you won't find any "factual evidence" that these "helix" bore spacers add any significant power. You won't find anybody running a device this on a supercharged Lightning engine.

As for the other items: If you do a "search" on here, you'll find that long tube headers add little hp until you hit the 400hp+ mark - even then, not a significant amount. The factory exhaust system (with the exception of the cats) isn't very restrictive until you start making some real power. Same for the single blade throttle body. As for the "cold air" intake - what most advertise as "cold air intakes" - isn't. Your stock intake system is "colder" than many aftermarket systems. There's all kinds of info in here on all the so called "cold air intake" systems available and the only ones that "approach" the "cold air" (ambient air temp) term are the ones that draw air in from outside the engine bay, as your stock system does. "Searching" on here will give you an idea as to what most think is the best system.

 

Getting back to the Dyno problem, Has anyone ever had such low dyno readings, or heard of any one having such readings. The I/C pump is working fine, could it be there dyno, or can you de tune the truck to such low numbers? if so I just been got for 600.00 bucks. Like I said it was a Mustang Dynamometer dyno, a very large dyno I might add.

 

I think that that Helix bore spacer is part of your problem.......maybe all of it Putting anything into the flow of air from the supercharger is going to restrict its flow; less air, less power. Remember, engines have to have 11-13 'measures' of air to one 'measure' of fuel. That mod is choking off the air and therfore, the power of the engine.

Take it out!

You look at others numbers for hp and tq for what you have - and you'll find that the "Mustang" dyno, due to it's operation, will indicate less power than a "Dynojet" will read - and most on here have used the dynojet type of dynometer.

 

your truck has serious issues. w/ a 3# lower and very basic mods my truck made almost 400/500 (not quite but very close)

So this helix space spins the air that then goes through a supercharger and screws up all motion of the air, that when not in boost recirculates?

 

I have money on it being the spacer thing. You have a blower forcing air into your engine at un-godly speeds. And then you restrict it by placing something in front of it that "spins" the air. It would also explain your boost guage dropping while on the throttle. The blower is trying to suck air in but the air spinner wont let it because it's basically just a big deterent. Get rid of it.
