    • Dinan working on F10 M5 S63TU turbo upgrade targeting 750+ horsepower - Built internals, lower compression pistons, and possible displacement (stroker?) increase

      We all know the new turbo motors from M mean more tuning and the S63 4.4 liter twin turbo V8 is in several M models meaning it will be a popular platform. Thus far only AMS Performance has announced they are currently working on a turbo upgrade. Now Dinan enters the fray as well and offers some interesting insight into the platform as well as the modifications they have planned. These include bolt on modifications (tune,intake,exhaust) pushing 660+ crank horsepower as well as suspension upgrades. Then there is the built motor turbo upgrade coming.



      BimmerBoost contacted Dinan and asked first regarding their bolt on stage upgrades. Dinan will offer a tune, intake, and exhaust putting the power somewhere in the 650 horsepower range. A dyno was asked for to corroborate the horsepower claims but Steve Dinan said as the products are not available yet no dyno or pricing information will be released.

      Dinan: We are doing software, intake and exhaust which will make around 660hp. Then we are rebuilding the engine and putting larger turbochargers on it and it should produce around 750hp. We are also doing a coil over kit integrating the electronic shocks, along with tubular adjustable sway bars.

      BimmerBoost: Do you have any dyno numbers to corroborate the intake, tune, and exhaust horsepower claims? Any pricing info as well?

      Dinan: All the power numbers are targets for development. There are no completed products (production versions) to measure, so we do not have any dyno graphs. There isnít pricing available as of yet, since we don't have the completed products.

      What is very interesting is that with the upgraded turbochargers Dinan is planning upgraded internals. Due to the higher compression of the S63TU (10.0:1 for the S63TU versus 9.3:1 for the S63) and the higher boost pressure at 22 psi versus versus 17.4 psi in the standard S63 V8 Dinan believes stronger pistons and rods will definitely be necessary. Additionally, a drop in the compression ratio. They also hinted at a displacement increase but it is unclear if it will come from bore, or stroke, or both. The motor features a stock bore and stroke of 89x88.3mm.

      BimmerBoost: Why rebuild the motor for only 750 horsepower which the stock internals can handle?

      Dinan: Different connecting rods and pistons for sure. They arenít strong enough to handle that power and the compression is too high for a lot of boost. Possibly a displacement change as well.

      Expect 750 plus horsepower. There is no timetable for this and Dinan obviously has a lot of work ahead of them. Still, very exciting times ahead for the new twin turbo V8 motors. It will be interesting to see if any of this development carries over to the N63 V8 as well which would make it a tuning bargain especially if built motor N63's matched the S63's which are based on the same basic design.

        Yeah - I am shocked how close they are - for some reason I thought the new "M5" was a lot faster. Much easier to make faster I guess though.
        Well the M6 shows how much shaving weight off it helps.

        Wow - you are right. The 80-120 km/h (all I could find) is dead even at 3.8s - the newer "M5" edges it out from 100-180 km/h @ 6.8s vs 6.9s

        Makes sense I guess - 400 lbs is a big difference.
        yeah the gap in performance isn't very big. That's why I'm saying it needs to come with more power from the factory if its going to weigh that much.

        Honestly I feel like bmw missed te mark on this car. It's just a 550 with a body kit, heavier (depending on options), and fake exhaust note. The engine isn't even unique it's basically the same as in the x5/6 m which is just a retuned version of the engine in the 550. The e60 was a real ///M the f10 is just a luxury boat with a lot of torque and m badges. @Sticky in response to what you said on the m6 yeah it's a little faster, but it's still a whale that goes into limp mode when you start to really drive it. I know these cars aren't made with track driving as the focus, but the e60/63 could go to any track (drag, auto x , or road course) any time and put up respectable times all day.

        I do not disagree with you. But the E63 will limp too. These are just heavy straightline missiles now. Short blasts, then cruise the rest of the time.

        @Sticky I haven't seen e63 limp very often, but yeah I'll give it to you. I think the e63 should have been a bit more focused on performance. Anyway didn't mean to get this thread off topic... This is a good package by dinan which will no doubt be over priced, but almost worth it because of reliability and warranty.

        Yeah, I agree with you G0TB00ST on missing the mark, I think a lot of people do - and think that it's a shame. However, it's good that Dinan seems to be doing it right, and to me reliability coupled with high power is a necessity. I don't care or want a car that makes 750 HP unless it can do it all day long without an issue - in other words, not just a 1/4 mile at a time. I am hoping they will address cooling/heatsoak (from what we have likely seen in the last published race) considering the amount of effort they already pushed into it, so hopefully it will bring out the "M" in the car more than BMW has.

        Maybe times will turn the tables, we will see.

        @Sticky also I know they are heavy straight line rockets and its sad. If you buy a bmw for straight line speed no matter what model you bought the wrong car. That's why I bought my e46 m3 over the 335 because at the time the 335 hadn't done sh!t other than haul in a straight line, there are a few track worthy ones out there now though. Hell I've seen old e38 seven series tearing up tracks (obviously modded, but still it's a 7). Bmw has lost their way especially the M division... Ok I'm done I've said my peace lol

        Was this an attempted F&F reference? And yeah I believe they will address the heat soak, or at least try. Also you are spot on about reliability! If anyone can get hp gains and keep it reliable it's dinan

        I disagree I bought a BMW because it does everything well. It's all around. It will never be the best in any single category but M's strength was always well rounded drivers cars. Well, it used to be.

        And yes, the M division has lost its way I never hesitate to mention that Click here to enlarge

        I never said they aren't fast in a straight line I'm just saying that's not all they do.
        Also does BB have an app? I was going to pm you about it but I'm lazy and it's easier to ask here (I'm on my phone)

        Agreed. They used to be good at everything.

        Built + more boost + upgraded turbos should definitely be more than 750 crank, seeing as other tuners are supposedly seeing close to that with exhaust and a tune. I'm sure its a conservative estimate. Being from Dinan, it will also cost about 20k. Can't wait to see what happens though. Also really excited for what AMS comes up with. I really want to see this engine make big numbers.

        It won't be cheap but being from Dinan it will also be done right and actually work as intended.

        Built motor plus upgraded turbos from Dinan will be a hell of a lot more than $20k especially if it's from Dinan and they are first.

        Did you see their stroker kit prices?

        Yeah you're right I forgot to take that into account...you'll be able to buy an M3 for what this costs. It will be done right, but I can't help but think it won't end up being a great deal. I am excited to see it though.

        It will come out expensive then they will drop it as time goes on and more options come on the market.

        I think Dinan is making the right choice for the customer base they are targeting. I am sure that most shops could make 750 HP with limited changes.

        I think Dinan is focusing on the customer who wants good HP and no problems. They want a car that will make 750 HP on 95 degree summer days, will idle through NYC traffic for 2 hours, run on pump gas, has a broad power band and lot's of torque.

        How to do that on a platform that you can warranty? Add displacement, add bigger turbos and over engineer the rotating pieces.

        From what I see, Dinan never talks about making the most power. They do talk about consistency, durability and driveability.

        I would prefer a car that makes good torque down low and has a nice flat power band. And will make that power on the hottest summer days. I have been there with cars that made high HP with peaky, narrow powerbands. They are fun; but, they are annoying to drive in real life everyday. I guess I am getting old.

        Exactly. Dinan doesn't go for peak figures for bragging rights. They go for a solid and reliable package. They aren't trying to squeeze every last horse.
