Default Stage 3+ dyno from KTR

Hi Everyone,

Here is a dyno plot from a car that was just completed at KTR.

Please, let's not start a this dyno sucks post. That is why I had them compare a stock S4, so we could all see the difference.

Mods:
Big-Port heads
RS4 Cams
RS4 intake manifold
RS4 Throttle Body
RS4 IC's and up-pipes
HSSSK045's from ITS
AWE MAF w/straightener and Software with sauce from Moss
LaBree DP's (Tantrumwerks.com)
BTW the plots are both on 93 octane

The sauce was off the shelf sauce with a Piggie MBC set up to only limit the initial overshoot. This is a problem on the bigger turbos if the sauce is not tuned for them.

Everyone was pretty impressed with the power it put out on pump fuel...

Default Nice pull. What's the 1/4 look like? And...

why in the h3ll hasn't someone done a work around for that whacky MAF other than to use a stock straightener which would flow even less than a Hitachi S4 stock housing?

Impressed... wondering how much more is in it.

Default We tracked a car with and w/o the wacky straightener-

Less than a .5 mph difference.

Could have just been changes in conditions.

I don't thing it makes a difference. Diego made a super custom "D-Flo" and only picked on .1 on the FATS test. Well within just a normal variation.

Default The whacky part is that AWE maf. Seems with the straightener

the total flow area would be less... understanding the straightener is more for drivability than load testing.

Have never understood the design purpose of that particular component in the kit. Anyone dinking with just the standard Hitachi housing out there? Know others that have replaced with blue oval components.

Just an observation, not picking. As always, Thx for the data.

My theory is that the larger the Maf size the more important it is to have an exponentially longer lead in. Or velocity stack. This can also be successfully accomplished with a straightener.

Should be about 1.3-1.4 bar.

Default I hate to jump in here, but long before the flow straightener was thought of, you have said

in the past that you didn't have a problem with the original AWE MAF Housing (before straightner's etc).

Please don't take this the wrong way, just trying to understand the evolution here.

Can you give me your impressions regarding the differences in drivibility with and without the flow straightner ? How much of an improvement ?, are you seeing similar improvements on all cars you install the straightner on ?, are some cars still a bit touchy even with the straightner ?

I know you have installed the EVO intake on many cars, this seems to have a similar effect. Do you prefer this over the flow straightner ?

What about using an Hitachi MAF mounted in an RS4 MAF housing, have you mobile-tuned any AWE Stage III kits with this setup ?

Sorry for all the questions. Your insight is appreciated.

Default Since no one else is asking...Is this the first proven/dyno'ed application of the HSSSK04-5's?

These HP and TQ numbers strike me as impressive. Is there anyway to quantify what those turbos did? What else will/can be done?

Are there any comparable cars running on plain K04s?

Default FWIW, I "demoed" an open straight maf housing with K&N directly attached

idle was perfect and no funny dips with clutch use. MAF values were stable at idle too, no low rpm hiccups. Only ran it for an hour or so, but I liked what I saw.

Green top injectors @ 4bar too.

No real flow straightener to speak of in that K&N IIRC.

Default Franz? Would that be Franz D that worked at 1552 in the late '90s?
