Mr Vanos/Arrow Rods + engine build time-lapse

BIMMERPOST
     Featured on BIMMERPOST.com
The S63TU engine found in the F10 M5 and F90 M5 along with it's variants is an incredible design, capable of making monster power with very few modifications. However there is one weak point as the power starts to climb - the connecting rods.

As standard especially on the F90 M5 the stock turbo's can produce so much torque that is bends a rod, potentially destroying the engine. Mr VANOS worked with Arrow to produce a drop in uprated forged connecting rod that is rated to take 1400NM of torque. This allows the engine to safely produce up to and over 1000hp, and run deep in to the 9s 1/4 miles.

We visit Mr VANOS and talk to Steve about the process and details of the new rods, and see an engine be rebuilt using them.

Great to see new engine upgrades for our engines.👍💪

But bent rods happens a lot because of incorrect engine tuning if you tune for high boost at low and midrange rpm you get high torque and high cylinder pressures this puts a lot of stress on the rods and also higher risk for knock.
You can bend rods in many cars by doing this it's better to increase the boost moderately in the lower rev ranges and increase it in the upper rev range ,you still get the same top end power and in some cases even more because less stress on the intercooling system i.e. lower IAT.

Also Imran do you still run the RK Autowerks built engine in your F90?

Agree. The RS3 DAZA platform will happily bend rods on demand just by swapping to e85 and unleashing the tune - stock everything else.

Feeding torque in appears to preserve rods.

My curiosity is what else fails?

Pure Drivetrain Trans is offering built ZF trans for 1200/1400 hp scenarios.

The ZF8HP 75/76 in these cars are tough they can take a lot of torque and abuse they don't need to upgraded until you put really high torque through them.

What happened to the built motor from RK?

What mods are done to the Auto to hold the 1000whp.. Assuming its wheel HP.
Seems odd that you built a new bottom end when you already had one built.

Initially we were planning on pushing further than 1000 BHP and sent the engine back to RK to have a sleeved block. While this process was happening we had a customer in the USA who wanted the engine quickly so we sold it. In the meantime I had change of direction and didn't want to push any further as I couldn't see the car improving too much over what had already and also wanted to concentrate funds/time on the G82 M4 xDrive.

This rod solution is the most cost effective way for customers run 1000 BHP safely. We are not looking to go much over this. So currently our car has a stock engine with just the rods changed to these new ones and it is what our customers are getting too.

No mods are done to the auto trans at this stage. I'm still on the original gearbox.

All right but you are going to install hybrid turbos right?

Yes running hybrid turbos now after maxing out the stock ones and getting the results we discuss in the video.

Are they Pure hybrid turbos? and what are the modifications done to them?
What horsepower difference can you expect by installing hybrid turbos?

At what point do you recommend the stronger rods ? Stock turbos plus Meth ? Stock turbos plus a full E tune or only with adding Hybrid turbos for big power ?

I don’t run race gas and don’t have E85 locally so I am mostly interested in what I can run on 93 pump plus meth. Compression is already on the high side for the kind of boost I run — around 26 psi. I would think higher flowing turbos would help me add power while not raising boost more than 1-2 psi. I don’t know the stock GT22 efficiency/power graph but would think that the 800 rwhp F90s are making that power in the 60% range.

Depends on the tune but stock turbo plus meth (with tuning for meth) would require stronger rods.

We are using RK Autowerks hybrid turbos.

Will share more data when we have it. So far 9.7 1/4 mile on Dragy is what has been achieved with FBO, stock turbos, 94 oct fuel, and meth.

We have these rods in stock at the moment for those wanting to build their engines over winter with their builder of choice.

US customers can buy from here:

What would u think typical or ball park price on install would be with these rods?? Just seeing how much it would be to buy the rods and install

I've gotten a few quotes in Texas in the 15-17k range.
