I dynoed my Alphawerks Header and Injen intake recently on hot ___ hell day here in South Florida 97 DEGREES!!! inside the shop lol their ac took a crap.. Take a look at the A/F ratios im using the antifouler mod. 4sp auto TC.

[/quote] Old dyno on a nice 80 degree day. Only mod was a K&N drop in filter, the Injen axleback is on the title ,but wasent installed at the time. A/F ratios are a bit rich as you can see.



http://home.comcast.net/~miamiprep1/Scan10004.jpg[/quote] Recent dyno again disregard the title, temp is accurate 97 degree. Only mods were Alphawerks Header and Injen Short ram stock exhaust took off injen exhaust due to rasp . Second run the last run was the best at 142hp 145 tq but i couldnt get that saved. A/F ratio just a bit leaner.

nice, how do the headers sound?

nice numbers

nice, how do the headers sound?

I got the stock exhaust so it sounds about the same, with the Injen short ram i cant hear my own exhaust. Im just waiting like so many ,for a reasonably quiet yet better flowing exhaust. I removed the the stock muffler on the shop, in one run and the numbers were very nice about 147hp 151tq. However this sounded like ___ :doh: so i promptly replaced the stock muffler, nontheless it goes to show that a I,H,E on this car offers very good gains.. Remember this a 4sp so the numbers are about 12hp 16tq lower then the 5sp. Not bad for an auto.

nice numbers

Thanks, will dyno soon with S pipe.

Hahaitsskippy dyno'd at 155hp with just tha AFW. I guess the heat really got you.

is Hahaitsskippy's car a 5spd? thats a pretty good gain from just a header

He actually Dynoed at 151.

His numbers where very good, cooler conditions than me and a 5sp. I almost did hit those numbers when i unbolted the muffler, it sounded really bad though.

i guess this can put the arguement to rest that 5sp are faster than autos

nice numbers btw

I dont think there was ever an argument on this, with the exception of turbo.

naw on another thread me and another memeber were argueing over the benifits of 5sp over auto and he made a comment "we dont even know if automatic produce less power than 5sp" he said something like that

Lol hes ignorant dont get worked up over it :rofl: 5sp have the advantage stock to stock. my baselines are only 126hp 130tq. At least my 4sp is putting the same if not slightly higher 142hp 145tq best so far, as a stock 5sp so i should be able to compete. Oh and my MPG hasent been hit it actually got a bit better.

your throttle response on the auto should be better then a 5spd tc becuase of the mods that you have. however it would be a good race because the manual tc has short gearing which makes it a good sprinter

Yeah, power at the flywheel is the same for auto and manual people.. it's at the wheels where it makes the difference, when gear ratios come into play.

hmm i think we knew that :clap:

Alpha headers and intake = around 12+ hp? yup thats about right...

those are believable gains.

that other pic with the headers by itself gained 13 hp??? thats such BS...

:) I was commenting on metalranger33's post about saying autos are faster. But yeah, his wording makes sense, and in my read through I figured it as a different meaning. Oopsies.

I actually got a peak on the 3rd pull of 141.8hp 144.7tq, i lost that printout so i scanned the 2nd pull which is this one.The 10hp 10tq from headers alone is very true, in addition my numbers might have been a bit better if it wasent so damn freaking hot in there. When i left my shirt was drenshed.

i cant wait to install ..... I wonder how much hp if u had ur injen on !

Hey Andrew ..well i took off the stock exhaust and the numbers went up very nicely, about 147hp 151tq from just one pull, sounded like crap though..i figure with just an axleback like the Injen it should be 6hp more. So perhaps I,H,axleback should yield 144hp 146tq minimum on a 4sp. Full catback and 150,s are attainable.

10-12% loss on the automatic, it shows right here. Still nice tho!

How much would throwing in a High Flow Cat hinder performance on those just mentioned numbers?

cool, cool tctunerz is finnaly sending my exhaust so well c. and im getting tech ill tell you numbers from that as well.

why do people continue to call them headers when we only have one?????

I have headers (header) who cares

It just like magabits and megabytes. The ignorant will say "who cares" and "it doesnt matter"while the ones who actually know will be annoyed as hell for all of eternity. Life sux then you die and all that. Oh well.

Not as bad as when someone used the term to me 'millibits'. That was a new one by me.

yea so any way nice dyno !~

yea so any way nice dyno !~


Thanks im going to order the S pipe and Dyno on a different dyno set at 75degree ambient temperature. Results should be better, i get free pulls so ill keep you guys posted.

dam tctunerz is sending my injen exhaust but i was the new cat back zip ! AGGHHHHHHH
