Hi Guys,

I've been seeing a lot of Posts about how low dyno numbers are for dinan software... Finally I have dynoed my car after the Dinan software on a Dyno Dynamics this weekend. Not absolutly thrilled with the HP results, however it does seem like its adapted to my driving style- More torque, speeds under 100MPH.

Included in this thread:

Baseline Dyno- 2009 135I with only a K&N drop-in filter.

Light bolt-ons- 2008 335I e90 with K&N drop-in, RPI scoops, Dinan Free-flow.

With software- 2008 335I e90 with K&N drop-in, RPI scoops, Dinan Free-flow, Dinan Stg. 2 Software.

Your comments are encouraged. If you have a Dyno sheet, and video to rebuttle... Please do!!!

Baseline: 275.5HP/ 290TQ

nice video +1 for posting

hmmmm

so you picked up 20whp w light bolt ons and no tune over that 135 (will have to assume you would also be around 275whp stock) and then only another 20whp w/ the tune?? Thats pretty bad, less than a SSTT or any other tune I can think of. Maybe a JB1 would give the same gains.

sorry if it sounds like i'm bashing Dinan again.......but the numbers dont lie.

[klipseracer]

There was a good TQ increase however.

yup! probably feels good on the highway unless you rev it out.

I have to assume the OP does not have IAT/Timing logs of the runs? Curious if the Dinan tune was pulling timing hard up top.

[Easternedge]

Ok, so here is the actual dyno sheet from the "light bolt ons" to "Dinan stg. 2".

The main thing that I see here that what makes the DINAN Modest is a Dip in the BLUE HP curve circled with a "?" mark...

The Stock HP curve goes to a peak, while the Dinan has a huge Lul in the curve. Can someone please chime in as to WHY i'm not getting another 20Hp from it?

Thats what breaks -

[stressdoc]

Pointless to have 135 as stock. Dinan exhaust does not add more than a few hp, and the scoops are irrelevant. A much more reasonable explanation is that your car (black E90) has a stronger engine stock than the silver 135. The Dinan stage II adds about 20-25 WHP over stock.

[klipseracer]

Looks like at about 5500 rpm's there were some problems preventing the peak HP numbers from being a lot higher than they were. Any chance we can see the A/F ratio chart?

[JayKay335i]

It just makes me cringe that those are jb1 type numbers. JB1s can be had for $1.

[GTR-Dad]

In my experience, area under the torque curve is what makes a car _feel_ fast in real world driving. Peak power is great for laying down faster 1/4 mile times, but only comes into play when you're revved right out.

The Dinan stuff I've read seems to be targeting real world performance rather than numbers. My understanding is that boost is increased at the bottom and mid-range, but dialed back at the top end to avoid overloading the FMIC.

Cheers,
Dan

$1 is what the jb (made in some ones basement) is gonna pay when your have a warranty issue


Gotta Love Dinan and their warranty plus its a 335 or 135 not a Supra yet... (gonna take a while for some real hp upgrades)

Being an M5 (Dinan S2) owner as well as just buying a 135 the Hp vs cost is always an issue... Real Reliable HP Costs $ Gotta Pay if you wanna Play...

[CubanJJ09]

What's the temp, elevation, cooling, gas used please. "Light bolt ons"are those listed?
Thanks for the info and thread.

Thats what a BT scan tool is for.. or even the Proceed RevII w/ canbus can also clear codes.. Warranty still active..

To be fair I think they are more like JB2 type numbers. $99 w/ 15-20 minute install.

Check out some JB3 and vishnu dynos.

Dinan S2 package for the e39 M5 is one of the most overpriced yet still very badass setups out there. Its what.....$40k installed right? For headers, exhaust, intake, maybe cams?, ecu tune, new rear diff, and probably suspension? I believe its a 80hp increase for that $$. I'm sure its a hoot to drive too.

I the S2 M5 so dont take that as bashing, its just a huge example of Dinan raping the general public for products that dont generally perform that stellar.

I was in a little get together with Steve Dinan himself and basically said after a lot of badgering from the guests that he makes sure everything is only a bit more aggressive than stock so that is overly safe. He doesnt want to have to foot the repair bills (actually he has insurance to take care of that).

So u get "under-performing" and over priced products BUT you get the warranty. Its a trade off that some cant live without, while others couldnt live with it.

so yup, like you said, you gotta pay to play one way or the other.

[Easternedge]

If i was going for straight speed... 'There is no replacement for discplacement", I would have got a Z06

But, I can fit 3 in the back 2 if ya' phat...

Still pissed the curve does not continue to go up and instead dips down... Freakin warranties!

*POST YOUR JB3, V3 DYNO CHARTS- Dyno dynamics preferred*

$40k for 80hp Now that is the most ridiculous crap I have ever read. If anybody payed that please line up now and take your shot in the groin for being a dumbass.

M5 Boys are a different breed young lad... It is 80Hp naturally aspirated german car!

Just an FYI of what a $100K M5 sounds like: (Not much substance, but you get the point)

What makes a stock engine stronger? I know we've all heard of "factory freaks" for all makes and models that are faster than others, but what actual parts of the motor account for that?
