Dinan Engineering S1 BMW M4 Review Thoughts and hearts and minds damaged in Bimmerland last Feb when Dinan Technology designer Bob Dinan remaining the entry of his own company to join in Processer Ganassi Hurrying in its make an effort to take the new Ford GT to Le People. An era certainly completed as the company, situated in Morgan Hill, California, and so long identified as one of the best suppliers of improved BMW program and elements, knowledgeable an uncertain future. But whether by real durability alone or the constant part of new control, Dinan Technology keeps on to end up incredibly enhanced improved gadgets for BMWs. Well, we’re certainly assured after producing the 530-hp Dinan S1 M4, which increases and refocuses a car that in stock kind is planning the road of extra GT.
For nearly 30 decades, Dinan has sent us demonstrators loaded up with a number of selection items, and in turn we’ve gushed with slack-jawed wonder. However, it’s getting more complex and more challenging for the improved to thrill us as auto producers get better at offering ultrahigh performance on their own or through specialized sub-brands. For companies like Dinan, there isn’t a lot of low-hanging fruits and veggies anymore.
The S1 M4 isn’t like most of previous times Dinans we’ve analyzed, in that it hasn’t had a cost-no-object engine gutting and repairing. With just $7247 in engine developments, along with a Stage 2 DinanTronics sign refresher ($2749), a freer-flowing stainless-steel muffler ($2499), and a carbon-fiber cold-air intake ($1999), the S1 is associates of family members members cope. That is, as opposed to S3-R M3 we analyzed truly, which had an amazing $31,234 in engine modifications alone. Okay, so this new car doesn’t present you with the strong engine mature we’re familiar to from Dinan, but it does announce a force of 105 equine power and 98 lb-ft of rotating at a sum most M4 drivers are able. Yes, it’s a somewhat shop cost but still cost-effective.
That’s because instead of a new engine you’re buying a Dinan sign refresher that piggybacks onto the car’s pc and types the incoming details to mislead it into producing more improve. This is a tried-and-true way of modifying engine result in an era of multiplexed and code-locked pcs. But in a BMW it is no uncomplicated problem, due to the complex features of the way the engine emotions its atmosphere and procedures everything from cam phasing to wastegates and more. If you’re going to protected a sign refresher into a BMW, you want it from a company that knows its company (and also provides 50-state-legal complying and a four-year, 50,000-mile warranty).
Dinan Engineering S1 BMW M4 Interior
The problem was that we couldn’t look at the performance claims on the evaluate observe. The S1 M4 ran from zero to 60 mph in 3.8 a moment, a Tenth more gradually than a stock M4 with the DCT computerized we analyzed last year. The Dinan transformed a 12.0-second quarter-mile at 122 mph—again, pretty much what we got with the stocker. We asked Dinan about it and technical house Casper van der Schoot responded at length and with several aspects.
First, BMW’s producer equine power ratings seem to be conventional, he says, and the stock BMW M4 does not make the marketed 425 equine power and 406 lb-ft—at least, not on Dinan’s dyno. There, it makes 484 equine power and 446 lb-ft of rotating. With the company’s DinanTronics piggyback set up, the capability improve is thus more like 46 equine power and 58 lb-ft, a more cost-effective (and believable) improvement. Dinan put its S1 M4 returning on their dyno after we analyzed the car to recheck the results identified that their car was still producing the mentioned 530 equine power and 504 lb-ft.
If what van der Schoot says is applicable, the most improvement in the 60-mph time you could predict is maybe 0.2 second, and that’s assuming the wheels and evaluate conditions were the same, which they weren’t.
Our M4 DCT evaluate took place A disease of the condition of michigan in Aug 2014, while the Dinan S1 M4’s evaluate was conducted in Come beginning june year in the California wilderness. Two locations, two different types of your. For the advanced level, California drives offer only 91-octane top high top quality energy, while A disease of the condition of michigan drives offer as much as 94. Also, California’s unique summer year months mixture of your prioritizes contamination reduce over power production, says van der Schoot. In their encounter, BMWs are very knowledge of octane modifications as well as high top quality, the pc highly contacting returning the key to prevent pre-detonation.
What does it all mean? All aspects being comparative, the Dinan upgrade may shape a few tenths off the stock M4’s performance, but it’s not going to turn it into a Bugatti Veyron. Analyze out Dinan’s website for the particular evidence the company provides. The seat of your pants will say it’s certainly not gradually, and in some mid-range conditions, such as dropping the kind of on the road to leap for an beginning, the Dinan’s improve does indeed at least encounter a little stronger and also sound more noisy and better thanks to the new exhaustion. We did see some reducing in the 30-to-50 and 50-to-70 times, by 0.1 second each, and a serious cut in our 5-to-60-mph evaluate, from 4.7 a moment down to 4.1, and in the run to 160 mph, which came by 0.8 second. So some extra power is definitely there.
Dinan Engineering S1 BMW M4 Features
The cancellation gadgets is perhaps the best use of sources if you’re on a sum wide variety. A set of versatile Dinan coil-overs features $1599, while new control arms that improve negative camber for better directing response are $1099. Add the versatile anti-roll bar set (two bars and elements for $900), and you have an M4 with all the fat produced out of it. Not that the stock M4 is reduce and reduce and flabby, but it does have a lot in complying that many company owners would get in touch with livable but some would get in touch with intolerable.
The Dinan’s cancellation modifications don’t make sure it is extreme, but it is stronger and stiffer over the challenging aspects. One's entire body system continues to be thinner through the edges, and the up-down activity is pared down to brief, connected shivers. Understeer is dropping, although if you go to a schedule, you’ll certainly have some, if not on the first lap then the third. Meanwhile, if you like a more track-oriented observe as your set up, Dinan’s suppliers are position by.
Rounding out the $10,984 completely S1 program developments is the $139 steel pedals.

With Pirelli P Zero Corsa wheels modifying the stock Michelin Cause Extremely Actions and scaly 275/30 in the top part and 305/30 in the back, the Dinan stopped with its producer foot brake in 157 feet and circled the skidpad with 0.97 g, similar research to the growth style but, unfortunately, a little bit more extreme. Let’s encounter it: Big wheels are for show.
Some of the Dinan items may seem expensive, but so is the M4 at $66,395 to start with (Dinan’s 2015-model-year car had a few producer options and was $77,050 before fettling). Start the hood and you discover out a amazing carbon-fiber restoration again for a structure get ready, under which is perhaps the best six-cylinder engine being created. Regardless of which improved company you turn to, if you’re going to improve on this show of spectacular technological innovation, don’t deface this program with cheapness.
