LOTS of interesting numbers here folks

We tested my box:

Stock
W/ questionable SPFR intake from the shootout
W/ SPFR intake from Jon's inventory
W/ SPFR intake that's been installed on my car for the last 2 months.

3 baseline pulls (1 in 4th gear for fun)
2 or 3 pulls with each of the intakes (and 1 in 4th for fun)

Some of the intake runs done back to back, no cooldown, jut to see what would happen to the numbers.

Tempature was a steady 65 degrees in the dyno room all morning.

Here's the results:

Stock: HP: 98.6 Torque: 103.4
Shootout Intake: HP: 103.2 Torque: 105.5
Inventory Intake: HP: 103.1 Torque: 103.7
Besk one's Intake: HP: 103.6 Torque: 105.0

Gains:
Shootout Intake: HP: 4.6 Torque: 2.1
Inventory Intake: HP: 4.5 Torque: 0.3
Besk one's Intake: HP: 5.0 Torque: 1.6

Odd how the shootout intake pumped out a 4.6hp gain and an extra 2.1 foot-Pounds of Torque isn't it?

But it's in line with the other intakes, and check out my 5hp gain with my intake!

both me and Jon couldn't belive my car dyno'ed over 98hp stock!! looks like i got lucky and got one with a really strong motor - but the 3 basline pulls in 3rd were 98, 98.5, 98.6 so there's not much to argue there.

I have pictures of the intakes installed on the dyno, as well as some video - if anyone wants i can put those up to, but i'm tired (been up ince 5:30 to drive out to the Magnaflow dyno center) and don't feel like doing it if no one cares.

 

I can't wait to see this .

 

Thanks a bunch to you guys who woke up early and got this done. Jon told me the results this morning before he posted them! I had a hunch my box was pulling more than 1 HP extra w/ Jon's intake, and his results pretty much confirm it!
Way to back it up too with some solid dynos! I stand by my previous statements as a satisfied SPFR customer!

 

IN FACT THERE WAS FOUR BASELINE RUNS, THREE 3RD GEAR RUNS AND ONE 4TH GEAR...I SAY THERE IS A BIG DIFFERENCE. LIKE I CLAIMED BEFORE AND STILL CLAIM THE INTAKE MAKES POWER....

 

These various dyno tests have me confused... If Scion advertises that stock motors have 108 HP, why do none of the motors with aftermarket intakes even reach that high of hP?

 

Hey Christy...
someone help me if I'm wrong, but I'm going to stab away at this!
The 108hp is measured at the flywheel...it always is higher than the actual amount of HP which is given to the wheels...I think it's a 12% difference. A dyno actually shows the real hp that the car is putting to the group...or WHP

 

WELL SAID DREW....

 

So it is true of all cars, and also varies if the transmission is manual versus automatic?

 

auto robs more hoserpower than the manual

 

Ok you had to make a stand for the intake. I like that. We are still talking less than 1hp which is within an acceptable margin of error from dyno days to runs to different dyno's. Same goes with the torque.

Lesson is you can't please everyone. It doesn't matter if you test it, I test it, a panel of engineers, magazines or whoever tests. People are gonna buy what they want based on what they feel.

As far as the intake quality goes, I'm assuming the intake is a rotomolded part? There are errors in manufacturing that take place. Nothing you can do about that, but try and catch them before we do.

 

WELL SAID, WE ARE WORKING ON THE PROGRAM FOR THE MACHINE TO GET THE PART CORRECT EVERY TIME.

 

yeah advertised is 108hp, but that is at the flywheel. You do lose horsepower when measured at the wheels due to drivetrain loss. There is no specific percentage though that you can use to determine what percent of hp you will lose. Only way to figure it out would be to engine dyno the car then run it on the chassis dyno to figure out your specific car's drivetrain loss.

 

thats good that u got your own dyno done!
now we all know what the SPFR intakes do..
depending on which one i get(good mold, bad mold)
i SHOULD put out 5 hp.. but it'll vary with each car..
im curious to how ALL the dyno shootout intakes
put out like 3-4 tq.. but the spfr only does 2 tq..
i think the TQ on such a small engine/car does a big
difference.. but ur intake "seems" to put out 5hp..
versus the injen's like 4.07@4.77tq..
do u think the SPFR intake will do better with 1 hp more but about 2.5
less TQ?

i know light motors reflect A LOT with a lil tq.. tq is everything!
hp is just where it peaks.. i really wanna know which is a better buy
now that we know the real numbers.. and has quality control been better now?

 

OH YEA.. i forgot to metion that the defective intake(scionic mark used) put out 3 lbs of tq! crazy! hahah why would a defective one give more pull like that?

 

nice numbers on the SPFR intake!

it looks like someone took the time to break their engine in properly to get 98 whp in stock form.

 

so what's the deal? why did the SPFR intake only gain 1hp when mark dyno'd it?

something doesn't seem right here. all the SPFR intakes look really consistent (within .5hp). it would have been great if you had tried an injen intake to see what results you got. i don't like this inconsistency between "shootouts".

i think we need an unbiased party to dyno the intakes. but is that possible? probably not.

 

What would of been nice is to see them dyno a injen or aem, etc., etc. along with the re-dyno on the spfr.

 

well, you can't have everything i suppose, jon tried to get an injen, but nobody he asked wanted to take their intake off their car for a day to let us borrow!

i'm sure jon can schedule another dyno session, anyone willing to wake up at 5am and drive out with us, and let us use their intake is more than welcome, we can document the whole thing, just like we did with my car - i know the spfr will post the same numbers after seeing what happened with my car.

anyone is invited, just so that we have some unbiased people there to observe the entire process.

so, the question is, who wants to donate their time and their intake?

 

are you running on stock wheels???
some of the norcal guys dyno'd their stock xb, only have 92.x hp...

so whats the deal?? :?:

 

BESK ONE CAR HAD STOCK WHEELS ON... MY CAR HAS 18'S.
