Everyone is talking and no one is doing so I took it upon myself to gather some of the major intakes on the market and take them for a dyno run.

First off before I go off on any information I would like to give major props out to

Chris and his Crew at HOOK-UPS Import Tek in Upland for helping me find out the truth. Without Chris's expertise on dyno testing and his calibrated DYNOJET none of this would be possible. He's very interested in helping out the Scion community so anyone needs anything please hit him up. He supported us and we should support him!!!!

Also props to:
Steve @ bBist.com for directing me to HOOK-UPS Import Tek. If you all don't know then check out the cool stuff that www.bBist.com offers.

Also to these people/companies for donating/lending intakes to the cause:
Dude w/ the AEM (Still in the box from the dealership)
The Crew @ Injen (Thought it was cool what I was doing even if it didn't favor them)
Eric @ E.L. Prototypes (Sorry about the last minute notice)
John @ SPFR (Has since taken the intake back for further inspection)***EDITED***

Anyways...here it goes.

Time:
Dec. 10th @ 12pm

Place:
HOOK UPS Import Tek
8455 Loma Place
Upland, CA. 91786
909-373-RACE

People working on it:
Chris running the dyno
Me (Scionic) doing the installs
Richard (aka CamoScion) doing the picture taking

Subject:
My Blue Onyx xB 5 speed w/ ~10K miles on it
Stock w/ the exception of a grounding kit by Happies (OG Scionlife member that has since gone AWOL)

Dyno:
3 month old DYNOJET that is well kept, well calibrated, well placed (towards the front of the shop and facing outward toward fresh cool air)

Method:
3 runs per intake with cool down intervals of 3 minutes
Doing a simple Baseline measuring the peak HP & lbs/ft @ the wheels
All intakes are brand new still in sealed package

Intakes: (in the order that they were tested)
1. Stock
2. AEM Cold Air
3. Injen Short Ram
4. SPFR Cold Air
5. EL Prototypes Cold Air

Results: (to make it fair I compared the first run results)

Stock:
92.73 Hp / 95.82 lb/ft.

AEM:
95.86 Hp / 99.09 lb/ft.
+3.13 Hp / +3.27 lb/ft

Injen:
96.80 Hp / 100.59 lb/ft.
+4.07 Hp / +4.77 lb/ft.

SPFR:
94.15 Hp / 98.95 lb/ft.
+1.42 Hp / +3.13 lb/ft.

EL Prototypes:
95.75 Hp / 98.82 lb/ft.
+3.02 Hp / +3.00 lb/ft.

This post is getting long so as soon as I get some questions and critiques I'll post the rest of the results.

 

man... i really had higher hopes for the SPFR intake...that is too bad.

Looks like injen takes the day.

 

I wouls however like to see the average power gains for the three runs done with each intake.

 

SPFR charged you--an OG on here, as well as at the meets...not cool! Anyway...

They got it in the butt in the end...When eric said 20 hp--looks like he was about 19 horses too high on his estimate.

Injen it is, if you want to run an intake it seems.

Thanks alot bro for doing all this...there seems to be a bad case of recommending ____ just because you are buddy buddy with certain companies around here instead of recommending them because they are good products....you all know who you are.

 

Just wondering...any dyno test or plan for K&N typhoon intake? cuz i'm getting one installed this friday as sponsorship...

just curious.

 

thanks alot for the intake shootout much props to you and everyone who helped settle this..

also, do you think you can post the dyno sheets? so we can see what was the hp thru out the entire RPM band.. if its possible if not its fine you've done alot already

 

hmmm thanks mark.
i actually was thinking about AEM but i expected
a lil more than ____ ___ for ponies.
i guess injen or EL is the best for the price.. BOTH under 200 bucks i believe..
and providing like 3-4 ponies to the WHEELS! not flywheels..

i think we should be careful on what we buy.
im sure the peeps who got SPFR must be ticked off
a lil cuz for the same price they could of had a superior product!
i would be ticked off. let us all have DYNO results or track results
or SOME KIND of concrete detail available before we do
recommending of products.. like.. OH YEA.. THIS IS GOOD and that is good..
i defiantly agree with jdmxb(not cuz he's my friend).. i just think
a forum is meant to LOOK OUT or help each other..
now if we all recommended the WRONG STUFF then we'd be
harming ourselves versus helping!

 

all of this info without the graphs is a little useless really..

Who knows, at LOW rpm, maybe the SPFR intake gives the best gains...which is where you would really feel it...

at what RPM are these numbers taken from???

 

Thanks for doing all the work Mark..you are the man!

See you saturday...hopefully you don't forget to bring my cd this time ..lol

 

Great post man...thank you sooooooo much....i was leaning towards getting the injen intake but i still had some doubts, but now i'm sold...thanks for providing us with some facts...keep up the great work man...thanks again

 

Honestly, the graphs wouldn't help you much--because most if not all Dyno numbers are taken at MAX HP/MAX TQ Gain.

Do you really want to see an intake making .04 hp at 2krpm, and 1.4 at 5.5k?

The point is, that the numbers are the highest amount of hp/tq gained THROUGHOUT the powerband at ANY given point.

By your logic...the SPFR could make it's mighty 1.4hp at 3k, while the Injen/others make the 4hp at 5.5k...and you would still rock the SPFR????!

 

well theres the dyno chart from INJEN..
the RED line is INJEN intake on the xB.
and the blue line is stock
SPFR is somewhere BETWEEN THEM 2(closer to the blue)
just eye it

 

JDMxb...makes sense.

 

alright, here's a question...
i remember there was a thread showing the dyno results of the SPFR exhaust and intake

based on these figures, are we able to extrapolate the intake hp numbers only? if so, it would appear that the intake makes close to four hp.
just wondering...there appear to be too many variances

 

hey i just noticed.. out of all the companies.. the one
that produced the LEAST amount of power MADE U PAY FOR IT!
ironic isn't it.. maybe it was their only way to TURN U away from
dynoing their product... but other companies were CONFIDENT
so they were like BRING IT! let the games begin

 

that sheet shows numbers for the intake AND exhaust...if i am reading correctly.

 

yeah, so can't u just subtract the numbers?
(intake and exhaust #) - (exhaust only #) = intake # Right?

 

I can't wait to get my Injen CAI!

 

BTW, thank you Mark for doing this.

It is greatly appreciated.

 

scionic, thanks for all the info, i am planning on getting one after christmas and that answer a lot of my questions, good work and thanks again. BIll
