DINANTRONICS Stage 3 (STD & CP Models) / High Performance Heat Exchanger

[Dinan_Engineering]

NOTE: The below items are PRE-ORDER Only. Given the extended production time table for the core of the heat exchanger we are releasing the products early to gauge demand and potentially start the ordering of the second round of cores sooner rather than later. This would alleviate any potential back order situation going forward. Our initial production run of cores are due in the last week of October so finished units would begin shipping the first week of November. Got to love 6 week lead times.

UPDATE: The first allocation of units has officially sold out. We placed an additional double order order of cores earlier this week so there may be a slight delay on shipping from scheduled release date to those that are ordering the heat exchanger after 9/27. We don't anticipate that delay to be more then 2 weeks however (11/18).



Dinan High Performance Heat Exchanger for the F8x M3/M4

Part Number: D780-0001A
Applications: 2015+ F80 M3 Sedan, 2015+ F82 M4 Coupe, 2015+ F83 M4 Convertible
Installation: 3.5 hours
Release Date: November 4th, 2016. PRE-ORDER only at this time.

Description: Heat is the enemy of performance. Keep temps down and performance will go up as a result of increased efficiency. It's really as simple as that.

In stock trim, testing made it painfully obviously that cooling was going to hold an even more vital role on the F8x platform to achieve maximum results. The stock cooling system heat soaks after only 3 pulls and allows the engine air intake temperatures (IAT) to rise dangerously. The ECU must then reduce engine power to prevent detonation. With the Dinan high performance heat exchanger the vehicle does not heat soak even after 7 pulls; more than twice the effectiveness of a stock setup!

Some may ask why change the heat exchanger and not the intercooler itself? Wouldn't it be more beneficial to go directly to the source of the charge air? The simple answer is yes, but at a cost. The stock system cools the intake charge by using a water-to-air intercooler; an expensive piece to engineer and manufacture. The cooling circuit for the water that feeds the intercooler uses a primary cooler (heat exchanger) and a smaller secondary cooler in front of the passenger side wheel. Through rigorous testing of all 3 of those components and multiple combinations therein, it was discovered that the most effective performance per dollar solution was replacing the heat exchanger with a larger unit.

Further testing focused on the heat exchanger produced the optimized design you see before you. With 60% more volume and 19% more face area than stock along with being a whopping 40mm thick (24mm thick stock) it becomes quickly apparent how heat soak is averted with the improved setup. While the unit could be physically thicker, the 40mm dimension was ultimately chosen with consideration of airflow requirements of the main radiator which is located directly behind the heat exchanger. A thicker core would diminish airflow and sacrifice normal engine cooling... potentially detrimental to the long term health of the engine. The increased physical stature of the heat exchanger allows reduction in water temperatures to the intercooler an average of 9° across the RPM range. The colder water entering the intercooler improves the efficiency and allows the intake air to be cooled by an additional 6° average across the RPM range compared to the stock unit. The reduction in intake air temps result in an impressive +10 HP and +20 ft-lb of torque gain without any changes in the engine tune. Better still, The cooling unlocks some significant additional power when paired with the stage 3 DINANTRONICS Performance Tuner.

Benefits of the Dinan High Performance Heat Exchanger for the F8x M3/M4:

• Gains of +10 HP / +20 ft-lb of torque on the stock engine tune. Additional gains realized when used in conjunction with the Stage 3 DINANTRONICS Performance Tuner.
• 60% more volume & 19% more face area than stock
• 40mm thick Dinan cooler vs. 24mm thick stock cooler
• 9° average water termperature reduction to the intercooler across the RPM range. Colder water improves intercooler efficiency and allows the intake air to be cooled by an additional 6° average across the RPM range compared to stock.
• Significant reduction in tendency to heat soak
• Rubber mounted for vibration isolation
• Track tested to ensure consistent performance under extreme conditions

Dinan F8x M3/M4 Stage 3 DINANTRONICS

In all of the track testing to date one of the recurrent flaws that always came up with our shop M4 was its tendency to heat soak after only a handful of full throttle runs. At that point the power would be reduced until the vehicle was allowed to recover and the temps decreased. So while those first few laps were fun and exciting the enjoyment quickly diminished. It was obvious from the get go that cooling was going to be major player in the platform. However, no one expected the results that were ultimately achieved when we dug into the heat exchanger and produced a tune to maximize the power potential of the more well cooled setup. It makes us giddy with excitement as to what may be achieved with stage 4 and the big turbos.

Stage 3 saw consistent 20 HP and 20-25 lb-ft of torque across the ENTIRE RPM range and in some places much greater gains in torque while also evening out the power delivery. The performance of the F8x platform just got so much better!

573hp/548tq and warranty sounds great!

Does the link price assume you do not already have stage 1 and 2?

In other words, Is there an add on separately for those of us with 1 and 2 already?

Website pricing is assuming you are starting from square one. When upgrading from a previous stage you are just paying the difference.

Can I run Stage 3 without High Performance Heat Exchanger? Do I still have more HP than stage 2?

Thanks

For warranty purposes the heat exchanger would be required for stage 3.

That said, it would physically run without the heat exchanger but you would be subject to heat soak a lot more quickly and often. The heat exchanger is whats allowing the bulk of the additional power to actually be accessible. The tune itself from a pure boost perspective has a VERY minor bump in boost (peaks at about a 0.5# but in most instances its around 0.25# increase ) so you would get some additional gain but no where near its full potential when paired with the heat exchanger.

To clarify, the link for Stage 3 provided above does NOT include the cold air intakes that were suggested with Stage 2 or the heat exchanger. More specifically, what precisely is included in the STD Stage 3 link? The Stage 1, Stage 2 and Stage 3 software?

[TurboSid]

I believe the link above is for just the "Dinantronics" software. You still have to pay separate for the exhaust, intake and heat exchanger.

I thought so....wishful thinking that it was all included!

Seriously...

Especially Dinan w/ warranty (in a good way, not knocking Dinan)

You don't got the sarcasm, right? Lol....

[yaymitch]

Can you just buy the heat exchanger separately? In other words, will I still get the benefit of better cooling without any other Dinan products on my car?

[Agamemnon]

I wonder what correction factor Dinan utilizes for its Dyno runs. The numbers for a stock zcp at crank seems pretty high. If Dinan uses a high correction factor, their gains for the tune will be higher. I have heard from many that the S65 engine is underrated by BMW but 63 hp worth? Probably not.

Yes, you can buy it separately.

Lower temps never hurt and yes you can get it separately. We have a few pre orders already going.

We have a S2 car here patiently waiting for the stage 3 upgrade

Its common for stock M4's to lay down 425 HP / 425 TRQ at the WHEELS on a chassis dyno. You can do the extrapolation but the underrating of a modern BMW "S" engine is very much alive.

As others have said. You can get it separately and still have lower temps which are always good as well as a bit of extra power. The associated tuning just extracts more of the potential power is all.

We expected the release to be a big seller but the amount of pre-orders already has us amazed. While I hate pre-releases, in this particular case, I guess it was needed so we didn't get stuck with a massive back log and wait time.

What is that difference if you already have stage 2? ~$257 tune upgrade plus the cost of the exchanger and install?

If so, that's not bad at all.

[RockinPA]

Do I have to have dinan exhaust and intake as well to have warranty coverage? (If I have AWE exhaust and BMS intake)

Very interested in stage 3. I know I'd need the heat exchanger in addition...

Thats correct just the difference between the stage 3 and the stage 2 tune. $257 is what it is.
