2007 Rabbit w/ HEP/UM SRI Dyno

[Geo]

I have a 2007 Rabbit with the 2.5L engine mated to a 5 speed manual. I bought the HEP SRI intake manifold from APTuning and got the ECU tuned by United Motorsports. I installed these parts when the odometer was reading just over 80k miles and am about to reach the 100k mile mark. I dynoed the car before the intake and got 147 to the wheels with a simple cone filter on the MAF housing and a gti catback exhaust. I still have the same setup but now add the SRI. I was happy with what I saw but could always use more with all the GTi's running around.

The dyno was done in 4th gear from around 2k rpm to 7200 rpm.
Mods:
-HEP SRI intake manifold w/ United Motorsports software
-Cheap Autozone cone filter on the MAF housing
-GTI Catback exhaust

The Dyno Sheet - FYI, no torque readings available

very nice
i wish the damn 09's could get to 7200.

They can with UM software... or just about...

6850 is the rev limit on the 2009 ecu.
its probably only a minimal difference like 5 hp
not that big of a deal. but i also dynoed mine a couple of times

Damn you have like no loss of tq at all. I made alil more hp then you did but my tq was only 165 I believe. Starting to reconsider putting back on a short ram intake instead of my CAI cause thats prolly where the difference is. I need to get my car sorted out first and get another dyno done tho, last time I dynoed it I lost a considerable amount of power. I have an ongoing CEL that comes and goes and still havent gotten that pinned down yet. Could be something with the tune itself but the dyno was also not reading completely accurately that day either. Good numbers tho man and the car looks good .

His dyno has no tq readings, but still solid increase of power

I thought UM Software + HEP Manifold was quoted to make 200+whp?

Like DrivenAllDay said, no torque reading :/

I was having a big issue when I first installed the SRI when the filter was on the MAF housing. The car would have a serious hiccup at high rpms under WOT. People were saying it's because the MAF can't read the turbulent air with the filter directly on the housing. So I put some distance between the filter and the MAf housing and the car had considerably less umph. So the filter I had was pretty dirty to begin with and I had just put off getting a new filter. Put a new one on (mounted to the maf housing) and the car runs great! Some say I could have gotten a few extra hp with lighter wheels, but I don't have lighter wheels right now The 17x8 OZ polaris on my car now weigh almost 30lbs

When I bought the intake and software, I read 194. I was expecting more like 180 to be honest, but I'll take 188

[tay272]

oh i gotcha, i thought the other line was for tq. cant really read which was for what since its kinda small. i also had some trouble with just havin a filter on my maf, thats why i opted for a cai instead

Geo where did you go to dyno the car? I've been thinking I should have mine done, and the place closest to me was saying it could be a while before they could get me in

[kiserhd]

It's been a while since I've been on the dyno so I might be mistaken, but doesn't 3rd have a better ratio than 4th? Again it's been a while so I might have it backwards.

This one was done by Thompson Motorsports in Nevada, TX. They were having a dyno day and made it sound like they do it one a month. They generally deal with domestics and haven't become familiarized with Volkswagens. I usually goto Alama Autosports in Arlington but don't like to drive out that way. I'm in north Garland near the Firewheel out door shopping mall. We had a group of us from dfweuros.com.

I am looking for a dyno a little closer to me now.
