[QUOTE=Modshack;472744]Quad intakes!

methinks 1100 is a bit steep lol Looks a bit easier to install then the G3 tho...

They dont last that long actually.

I tested the stillen intakes on my 370 sport 7 AT. I have a dyno run for every Mod that i have done to the car.
Base line 265. RWHP SAE The car was bone stock
Stillen G 3 284.9 RWHP SAE ( bumper was on the car ) NO tuning stock ecu
It made these #s after 3 pulls on the dyno.
19.9 RWHP SAE gain.
I also watched the intake temps with the Cobb and they dropped from 80 degres to 60.1 when the car was on the dyno. the room temp was 58 to 59 degres.
The stillen G3 is a great intake $ for RWHP best mod that you can do.

:werd:

That's a lot of gain for an intake, regardless of brand. Dynos typically produce wildly fluctuating numbers even on the same day. For example, I have seen the local dyno produce numbers that vary by +10hp simply by letting the engine cool for 15 minutes after a pull. Saw that happen the other day on 3 different cars.

My engine made 260.1 when it was hot.
I know make 320.1 rwhp with the G3 , berk cats. Stillen CBE. underdrive pully. and my own cobb tune on 94 sunoco.
With 292 rwhp it ran the 1/4 in 12.8009 .
On my car there is a 5 hp loss on a hot engine.

1% loss in HP for every 10 degrees in temperature increase they say, so CAI should be better. I have R2C short ram intakes installed and did not notice any real gains, but also no loss in power - just louder. Since I'm still trying to pay down my debt, I have no money for a dyno run. Someone wants to sponsor me?

The thing I liked about the TS intakes is that they showed a nice gain across the powerband. The Stillen ones seemed to only produce top end gains.

Am I wrong?

nd for that amount of money I would wait for someone else to buy it and do some numbers for us. And it better have a money back garantee.

I can't speak for anyone else's results, but my gains from the G3 appear to have been pretty even across the rpm range.

After:.

It's a little tough to tell because they're not overlaid. Plus it doesn't help that the increments on the y-axis aren't the same. But pick any point on the rpm band. Take 5k rpm, for instance. On the before graph, I was making around 210, maybe? Defn. less than 225 whp. On the after graph, at 5k I'm clearly above 225 whp, it looks somewhere around 233 whp. Even as low as 3500 rpm. On the before graph I'm making just a hair shy of 150 whp. On the after graph, I'm making around 165 whp at 3500 rpm.

is that not what baker nissan did??

Good stuff. THX!

I noticed my hks intakes had a funnel like device on the inside of the tubes, does anyone elses have this? Think it might create like a vortex like air flow but not sure. I got 281.72 whp with 231.56 tq on a dynojet with I/E/HFC's not sure if this sucks bad or not.

I think thats called a verturi (spelling?) affect. It is kinda like a funnel to help make the air have more force or something like that.

It's actually called an air horn, venturi's are what are used in carburetors and cause a pressure differential. air horns try to smooth the flow of air entering the pipe from the sides to reduce turbulence and increase flow. All the crappy JWT popcharger kits have one. You see them on ITB setups as well.

So are JB370z's good or not?

Your comment does not make sense. They ran the car for 25 minutes with the TS intake on BEFORE the dyno. The engine bay would be hot already.

I have read this thread several times over and do believe this was a valid test. TS made more power and torque than Stillen. The torque thing is HUGE to me.

I am curious of the A/F ratios however. I would not want a car running too lean so that it starts pinging in the hot AZ weather..

^ why you dont want ur car to be so lean?? I heard that more lean = more power...
and tune will gain some hp while fixing the lean... and yes i love my car to go lean.. so i can tune it and fix the lean and get free more HP :D

Too pricey for me, but probably is a good short ram, I want SG3's but for the moment I am running my do it your self <200 buck Sunday project with stock MAF housing and accurate fueling (confirmed via WB)
Sounds great, throttle response IS better, un dyno'd so cannot comment on power, although it 'feels' better then stock intake system.

I hear ya!!! :tup:

I would be curious as to the TS MAF section diameter compared to the G3 diameter. The only way the SRI will make gains is by increasing the diameter to make the car run lean and thus make some power, but the G3s do that too. I mean no matter what its a filter on a stick and there isonly so much one can do to make gains and they have all been tried and all intake makers know the tricks so I find it hard to believe the TS made more than the G3 without doing anything else to the car or dyno. They will suck in more heat than the G3s, so they have to make up for that lose somewhere and whatever they did to do that, others know it to and would have done it on the G3 too. So its all a crap shoot really and you just get what you like.

Another note Im curious about is, coming from GA to Tx and now being at a higher altitude my car is slower than it was in GA. What was the altitude density for the G3 dyno and the TS dyno? Could this make a difference in numbers?

I never got a reponse, I was wondering if this is a crappy number. Someone told me it was.:rolleyes:

what were your numbers before? Dynos are only good for a before and after reading to see gains as they can be calibrated so many ways, Thats why one can show a high gain for a mod if they really wanted to, they tweek the dyno.

Also not all cars come from the factory with the same power, some more, some less, so you may have gain good amounts but you need the before numbers.

Some companies are using venturi style intakes to help increase the velocity of the air as it comes in. Stillen has even used this design before. I dont know if its just another name for the air horn or a different design but they are using it in CAIs. Again just a way to try and increase the velocity of the air.

it's just a misnomer for an air horn as putting a venturii in an intake would be a bad idea as they only increase velocity within the are of the venturii once the air passes the venturii section and expands back out it is slower than it was before it entered due to the restriction upstream. It makes a good corporate buzz word though when selling an intake FEATURING PATENTED VENTURII VELOCITY ENHANCERS!!!! The only real place for a venturii is in a carb. Air horns just seek to guide the air's entry path into the pipe to reduce turbulence and increase flow so they don't cause restriction. It really isn't going to cause HUGE gains though. I'd wager that the top secret intake may have a different diameter MAF pipe and it is running much leaner than stock to account for it's power gains. That and foam filters aren't very restrictive because they don't filter well at all personally i fell that if you are running a foam filter you might as well just run a fine mesh stainless drag filter as they both just basically filter out the big chunks.

ZSteve - To you question about altitude for this dyno, no that would not make a difference here as both cars were dyno'd in the same shop. Good thought though....

I have a question in general, if running lean can make more horsepower and can be bad if too lean, how does a tune make even more horsepower after that if they adjust the AFR to be not as lean? I would think you would lose power but it would be safer on the engine.

You make peak power both sides of the equation, you can tune for peak 'rich' or peak 'lean' power, each fuel will vary for the total end target AFR/LAMBDA.
Obviously the target will vary depending on particular vehicle set up/conditions , but generally most will share the same ballpark.

also tuning advances the ignition curve and that advance is good for making solid gains by itself. Many tunes for these cars also feature raised redlines and extending the power curve is good for a few horsepower as well although it is superficial as you won't see benefit unless you are that high in the first place.

Sure tuning is way more then fueling, TBH you can tune via EGT and not even look at AFR if you are experienced enough and have correct probe placement, personally I prefer a WBo2 to relay my accurate fuel readings, EGT FB is very useful in tandam for an accurate balance of fueling and ignition, but hell, look at a rom image from any vehicle, soo many parameters that can effect the ultimate outcome, its a fine balancing act to get a smooth, reliable, well targetted, accurate vehicle.

Thats why I tune my own cars.
Yes I have popped a motor in the name of science lol

My 7 AT made 260.4 to 264 stock on the dyno, with the stillen G's it made 284, with the bumper on and no tuning of the car.
it made an honest 20 rwhp. (SAE).

Was this car tuned at all? We all know the stillen intakes lean things out a bit to make more power. HOWEVER Stillen recommends having the car tuned if you have thier intake, exhaust, cats and HEADERS. This car in this test had HFC's and Headers, which means it was running too lean to begin with, hence the power loss with the stillen intakes. Throw on the new TS intake and all the sudden the AF ratio richens up perfectly to make more power.

so whats the final verdict? does everyone agree with the TS dynos and numbers being better than the stillen G3s? Im about to pick up the TS intakes for a good price.

My old lady would kick my *** if I bought a pair of intakes for almost $2k.

With all said, I agree that the shorty intakes lose power due to heat soak, But maybe they used the first or second run only? Also I think I would be more apt to ask why the car only made 286 with headers and and HFC's. My car made 298 with stock cats and headers? ( mustang dyno) Not inflated numbers/

Share what is a good price you found ?

An arm and only half a leg :)

Im not sure 1300 more for the top secret intake is worth a 5hp 7Ft/lb Tq. I LOVE Top Secret but... Just doesnt seem worth the extra money.

I'm surprised no one questioned the air filter. Those mushroom style filters def. filter a ton less vs your standard oiled or dryflow filters, but flow more. I'm sure this attributed to the numbers slightly.
