Yesterday I put my car back on the dyno to see how my new intake works. Results were a bit disappointing. In short, I gained nothing at all. No extra boost, no extra power. If you overlay my first runs with my latest, they look like one line. Weather was roughly similar, gas is from the same station. Changing AFR from 11.5 to 12.0 did almost nothing, as did giving it more timing. No knock retard to speak of.

Peak power was 410rwhp. That's 10 more than last time but that's from leaning it to 12:1 and extending the rev limit.

I am not sure what the deal is at this point. I think maybe the stock exhaust is holding me back. What's the most power anyone has made with completely stock exhaust?

I'm attaching a pic of the intake. It goes from 4" to dual 3" pipes just like the D3 unit and the Spectre intake.

The Upper looks similar, but the lower isn't even close. No offense but It looks funny. I think the angle at the end of your intake is hurting you. You need to do a little more R&D.:thumbsup:

Oh yeah, almost forgot............................Find some power out of that thing. You have to make some power before you can compare it to a D3 or Spectre as they both made power.

I hope you know I am bustin your chops...... I'm sure you will find some kind of power gains.

Are you going to grind the welds?

Also:

What pulley do you have on? Maybe you are getting some belt slip and loosing boost? Lets see a better shot of your pulley set up.

 

[TimmyC]

How is my lower any different than the Spectre or D3? It's a piece of 4" tubing with a 45 degree bend and a filter on the end.

There is something screwy about the Spectre intake test. That car made terrible power stock and on the lower end of what it should make stock after the intake was installed. That test doesn't hold any weight with me at all. My car makes 70 more rwhp than the test car even after the intake and the test car had Corsa exhaust on it too. Unless there is a tennis ball stuck in my intake that I'm not aware of, it is not the problem.

Let me test one of yours on my car if you want usable data. I'll even put a deposit down if you want.

So is this the controversy you are trying to create? Maybe this email will refresh your memory:

I haven't put much thought into it at this point. I'll have the intake off tomorrow or Sunday so maybe I'll try to get that pulley installed.


Hey I posted in your intake thread, I hope you don't mind. I just don't see how an intake is going to be worth 44hp. You can post and call me names if you want, maybe some controversy will get that forum going, it's slow in there!

 

[PGA2B]

I'm not going to get drug into a pissing match with you. The numbers are the numbers. Take them or leave them I don't care.

Make some power before you throw stones.

 

[TimmyC]

Actually it's not. I was skeptical then, but I only got pissed after you said the D3 and Spectre intake "made power" and my intake did not. The three intakes are so similar they are interchangeable.

I will put the Spectre intake on my car and dyno it exactly as it is right now. I will tune the MAF chart if necessary and post the results. I'm not selling anything here so I don't have any reason to doctor any results.

PS. Posting emails without permission is generally not highly regarded. I don't have anything to hide so I don't care, but it's not cool.

My car makes 70 more RWHP than that test car after the intake install.

Don't get mad.

You said it not me.

Oh yeah, and my dad can kick your dad's a**.

Tim- In all seriousness, take a look at your Supercharger settings in your tune. I think you can get more out of it. Also I saw where Jesse said to play with the cam settings. You may have found the "Wall" the Coach found. Log your Injector Pluse Duty Cycles, maybe you are maxing out the injectors.

 

[PGA2B]

I'm done.

 

[TimmyC]

Lots of people bought that Spectre intake so we'll see what happens when people dyno with those. Hell, I'll buy one if the 44hp gain holds true.

 

[1madstsv]

Looks very close to my intake I saw a 14hp gane but had exhaust on my car my. Good numbers though my car stock was 365 now 379. So 410 is very good. My cats are gutted and my supercharger is off being reworked for more boost and I have meth. Hoping for 480rwhp. As for a d3 intake on a xlrv it made 10rwhp at a shop that nothing to do with selling caddy parts. As for other intakes time and dynos well tell the story I hope they do make big numbers but highly unlikely. It would be to easy and these cars are not easy to get power out of. Best of luck to all.

Dude, I really, really, hate your posts on here. I almost wonder if you know anything about cars at all. First off, Spectre is a reputable company. They are not going to throw their entire company reputation on the line to appease 15 STS-V owners when we account for maybe 1% of their total business. If they say 44hp, then you can be sure its 44hp.

I called you out here:

With no response.

And that was mainly to this amazing post:
http://www.cadillacforums.com/forum...-how-many-us-using-hp-tuners.html#post2501700
Where I asked:
"You got 400 rear wheel by just adjusting the AFR? I got 360 with plugs and exhaust. Hmm..."

That was a month ago, and you have yet to provide this paperwork showing 400-430 REAR WHEEL horsepower with just a tune. I'm calling your bullshit, dude. 99% of STS-V owners here are showing ~360 rwhp with little to no mods. Please, shower me with your knowledge that gives a bone stock STS-V 40 to 70 more REAR WHEEL horsepower with a safe tune.

Not only have you not provided that, but I see you on here disputing spectre's claims on their intake, and you supposedly have some home made walmart intake you cannot get 1 horsepower out of? I'm still astounded as to how you squeezed 40 to 70 more horsepower than anyone else on the planet with a stock STS-V. Its beyond looking like you have no clue about car performance, at all.

Then there is this post:
http://www.cadillacforums.com/forum...forum/219381-finally-got-v-2.html#post2479269

Oh, you'll be making your own CAI kits? Is that why you are on here disputing Spectres' complete, researched intake before they have even been shipped? And you, yourself, cannot even get 1 horsepower out of your own walmart home depot autozone CAI kit? Nothing is adding up. Hopefully you can provide some actual proof in one of your posts and I'm just wrong about everything. Until then, stick to rebuilding your wrecked STS-V and leave the performance stuff to the guys putting useful knowledge on this forum.

What kind of proof do you want? I posted the dyno sheet from my first run in my other dyno thread. My tune is 12:1 AFR, high teens timing. Stock is 10.5:1, 10-15 degrees. My tune is on the HPtuners board if you want to look at it.

As for my car being rebuilt, have fun with your payment book. I owe zero dollars on any of my cars.

Sorry, but if you believe that I've got a bridge to sell you. Its pretty normal for performance parts suppliers to over inflate horsepower claims of their products. Thumb through any of the major car magazines (MT, C/D, R&T) and look at the K&N - whom I would consider a reputable company with sizeable sales - ads in the back. They'll claim 20+hp gains from their intakes on Vettes, GTO's, other LSx vehicles. Real world, you'll be lucky to see 5-8 at the wheels. The HP TV guys were the worst with pandering to their sponsors. They'd take an LS1 Camaro on the dyno and baseline it at 270rwhp (I've never seen a stock one do less than ~295, most are over 300), throw on a K&N and Flowmaster, gain the 30hp up to stock levels it was missing and spend the last 5 minutes verbally fellating the sponsor about their products gains.

When I saw the 44hp gain post on the intake, I knew it was bunk. GM powertrain engineers are bright fellows. They're not going to leave that kind of power on the table simply by changing around the intake ductwork.

 

[LITTLEELVISDAN]

I got my D3 stage 1&2 intake for 1 reason.... It sounds a lot cooler than the stock intake. Much like a cat back exhaust.. Nominal gain if any but sounds much better than stock.....

Unless anyone can get passed the "brick wall" some of us have seen trying various things to see any real substantial gains, I am quite happy putting on noise makers.

 

[The Raven]

I fully believe the Spectre claims. I bet you that if I put that intake on my totally stock car, and then got a dyno tune and test, I would see comparable numbers. The intake alone isn't going to do it, HOWEVER the intake does allow more to be done on the tuning side, and that's where the real power is unleashed.

You won't see another 44whp if you throw the spectre intake on a car that was already making 400whp due to other mods and already had a good tune. You'll probably see nothing until you get it tuned again, at which time you may see another 10whp at most.

It does make sense when you think about it.

I will certainly be purchasing the Spectre intake first, then get a full dyno tune and test. That way I should be damn close to "500hp" (fw) with almost no compromises (no worrying about the overboosted SC, no loud obnoxious exhaust...etc).

 

[cadillac94pimpin]

Theres also no heat shield on your intake. I am not sure how much a heat shield will affect the intakes performance but I am sure it does. The stock intake pulls fresh air from the bottom of the bumper. Almost like ram air but not really. It was a decent design IMO. Our cars get pretty damn hot quickly so a dyno run with a warmed up or hot engine will probably have some kind of impact on numbers.
We will find out when people start to get there intakes and have some dyno sessions.

 

[The Tony Show]

You guys can debate intakes and numbers all you want, but stop attacking each other personally. Keep it civil or it gets shut down.

If they got 44 with the intake + tune, that explains it, and the tune was probably at least 30hp worth. Stock tunes from the manufacturer on factory forced-induction cars are always extremely safe, ie pig rich and low timing. They need to account for everything to make the motor last the warranty period - 120F ambient temperatures, customer abuse, bad gas, poor maintenance, failed IC, etc. Leaning things out just a hair in the hands of an owner who takes care of his vehicle will leave enough a factor of safety and see good power gains.

Basically for an apples/apples setup, which would be stock + tune followed by a dyno pull of the intake + tune, I'd bet you'll be in the 10-15rwhp range for the difference with the intake. Which in my mind is still sufficient returns for the investment.
