Dinan 750hp F10 M5

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

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.



We 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.

Q: 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 isn’t 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.

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

Dinan: Different connecting rods and pistons for sure. They aren’t 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.

Damn. I'll believe it when I see it, but if any of this is true, it is very promising. 5.0L S63tu Stroker? 900hp? Sign me up!

I am excited to see their coilovers with EDC compatibility as well as their tune, intake and exhaust.

All in for the coilovers with EDC and interested in the other upgrades but knowing Dinan this is all 3 years away minus the basic tune.

Agreed. They are way behind in releasing at least exhaust.

Rumor is that coilovers are coming by end of year.. We shall see. I will purchase these if true.

Anything else from them is too stale for my taste.

Just eliminating the top end limiter would be fine by me. Extra horsepower isn't much use on the low end and I would like to be able to go 175-180 with the car. I have all this horsepower and all I can do is 157. The car can go a lot faster so what good is more horsepower? I can beat any car on the road 80mph and up. No one passes me if I don't want them to. Plenty of horsepower as it is.

+1. Especially since Dinan won't boost the torque up much due to the DCT.

Too much torque already for the differential anyhow. I get substantial back end slip shifting at WOT in low gears. When I got stage 2 on my 535i, it was a lot of additional torque on the low end and all of a sudden I was getting back end slip where I never had it before.

This car is just damn powerful already and I am more interested in going fast on the top right now. I can't do that with this PMF limiter on.

+1 I know it wouldn't be cheap but I'd like a limit delete only option!

Stealth says he can do it in 5 minutes. I looked in the coding cheat sheet for the F10 and didn't see a variable that would do it. Maybe I was looking at the wrong sheet.

Maybe stealth will tell us what the variable is. Of course you would have to be set up for coding the car. I am kind of surprised the limiter is accessible through the things controlled by coding. I had the impression that the speed limiter would be part of the engine control system.

If the kit is anything like the E9x M3 kit you'll be disappointed. Too much money for basically a sleeve over.........Phil
