- CarBahn EVO Intelligent software adapts to various fuel octane levels seamlessly, optimizing performance without compromising safety. It retains existing safety features and adds extra protection as needed
Philosophy:CarBahn’s EVO intelligent software possesses remarkable adaptability to a large range of fuel octanes. Through our software, we employ retuning techniques while ensuring that all critical safety features, which are often neglected, remain intact and add additional safety features where necessary. To gain a deeper understanding of these safety limits, we invite you to watch the informative video available at this link. By recalibrating the safety limits, our software seamlessly adapts from 93 to 100 octane, eliminating the necessity for a customized tune when employing race gas. This unique functionality enables the software to deliver maximum power with each octane variant without compromise. Consequently, there is no need to purchase a custom tune exclusively for race gas usage. Our software is meticulously designed to provide the highest achievable performance output while upholding safety as a paramount concern. Here, the term “intelligent software” denotes the accurate and optimized tuning of the software, avoiding excessive tuning. Our objective is to craft a torque curve that maintains a natural and harmonious delivery, as showcased in this link. We avoid generating excessive torque at low RPMs, which could result in tire slippage, engine stress, and drivetrain failures. By managing torque with a smooth delivery, our software enhances drivability, thereby fostering increased speed and reliability. In contrast to our competitors, who often attempt to maximize performance by pushing boost levels beyond safe limits, our approach prioritizes reliability. We refrain from compromising knock sensitivity and thermal protections, which are vital for safeguarding the engine from potential damage caused by extreme power extraction.
Durability:
Unlike most tunes available in the market, CarBahn’s software maintains the integrity of safety parameters, preserving them to prevent any compromise in engine performance and longevity. Parameters such as knock control sensitivity, super knocking control sensitivity, and catalyst thermal protection are carefully tuned within your OEM software to mitigate the risk of engine and catalyst failure. In our pursuit of optimizing power delivery, we have minimized power losses to a mere 12 HP when reducing these supposed power-reducing software protections. On the contrary, we have witnessed numerous instances of damaged engines resulting from the reduction of these safety parameters. Thus, it becomes apparent that gaining a marginal 12 HP advantage hardly justifies the potential risk of significant engine damage.
Do-it-yourself Approach:
It is essential to acknowledge the emergence of self-tuning tools in the automotive market. While these tools offer the convenience of tuning your vehicle independently, it is crucial to exercise caution. Many of these tools come equipped with pre-set programs that conveniently bypass safety limits, thus posing a substantial risk of engine damage. The art of tuning a high-output engine requires profound knowledge and experience to extract maximum power without compromising the engine’s structural integrity.
Emissions Legality:
Let us address the topic of removing the catalyst, commonly achieved through the utilization of downpipes. Our rigorous testing regimen involved conducting consecutive dyno runs with and without the catalyst, and the observed power gain was significantly smaller than commonly touted, typically around 11 HP. Nevertheless, it is important to acknowledge our shared responsibility towards environmental preservation, as clean air is vital to our well-being. Furthermore, obtaining the necessary emissions certifications without a catalyst is a daunting task and, from a legal standpoint, it is considered an infringement.

Philosophy:
CarBahn software is designed to deliver the highest safe output possible. Smooth Power means software tuned correctly, not over-tuned. We always try to make a natural torque curve, not excessive torque at low RPM that falls off rapidly at high RPM. Excessive torque will break the tires loose, break the engine and drivetrain. Managed torque with a smooth delivery makes the car easier to drive thereby faster and more reliable. Most if not all our competitor tunes attempt to run too much boost, resulting in active knock corrections which causes surging during acceleration. CarBahn software also incorporates torque reduction in 1st and 2nd gears for manageable power delivery.
Durability:
Most if not all tunes on the market except CarBahn reduce safety parameters in the software in an attempt to extract more power. These safety parameters such as knock control sensitivity, super knocking control sensitivity, and catalyst thermal protection are tuned into your OEM software to prevent engine and catalyst failure. When we reduced all the supposed power robbing software protections we lost less than 8 HP and 8 LB/FT Torque. We have seen many damaged engines as result of reducing these safety parameters! It hardly seems worth it for 8HP.
Doing it yourself:
A note on self-tuning tools. There are now programs available that you can buy to tune your car yourself. Many of these tools come with canned programs. Be careful as tuning a high output engine requires tremendous knowledge and experience to extract maximum power without damage.
Emissions legality:
A note on down pipes (removing the catalyst). We have run back to back dyno runs with the cat on and off and the power gain is much smaller than most people claim. We all need to breathe the air. Its difficult to get your car its required emissions test without catalyst and it’s illegal.
High boost with stock engine:
We have seen many damaged engines as result of making too much power with a stock engine. While modern engines are very reliable, it is easy to add large turbochargers and water methanol injection and break the engine. On the F8X, maximum safe power on a stock engine is 600 LB/FT flywheel torque. CarBahn makes high performance engines designed to handle more power. More information is available on this web site.

As the world leader in BMW performance cooling, CSF has taken the lead in introducing a full-line of competition-grade cooling products and complete packages for the B58 engine
As more vehicles start to become raced in competitive motorsports, the glaring overheating issues that plague this platform have become even more apparent. CSF has answered the call with the release of new High-Performance Auxiliary (Side) Radiators as well as a world exclusive Dual-Core ZF 8HP Transmission Oil Cooler.
Don’t be fooled by other high-performance aftermarket options that utilize the OEM plastic rock guard. The OEM rock guard’s vertical channel design is specifically designed to only work with the tube spacing found on the OEM core. When the OEM rock guard is installed on an aftermarket radiator, it actually blocks a significant amount of surface area, detrimental to the intended performance. During CSF’s own R&D phase, CSF analyzed both the OEM and other aftermarket offerings and decided to take the extra step, redesigning the included rock guard to allow maximum flow to the radiator core, but still offering ample protection from small rocks and road debris – all proven on CSF’s in-house wind tunnel.
CSF’s new Auxiliary Radiator fits both the left and right side of the vehicle as a drop-in fit, requiring no modifications to install. Featuring CNC machined mounting brackets and OEM style “Quick Connect” inlet/outlet connections for a true plug-and-play installation that does not interfere with aftermarket performance aero modifications.

CBB58-6205 – B58 Stage 2 High Performance Engine for B30B 2WD
This B58 engine is designed to make for maximum power applications (over 1,000HP) CarBahn has designed a high-performance engine to handle very high outputs by pinning the cam sprocket to the crankshaft. To ensure durability we also machine the block to accommodate a full circle thrust main. In addition, we utilize higher quality racing Carrillo connecting rods, forged CP pistons, cylinder head studs, high performance valve springs, cylinder head porting and lowered compression for increased flow and high boost.
The stock engine compression ratio is relatively high due to the Corporate Average Fuel Economy (CAFE) standards which push for consistently higher fuel economy in cars and trucks. However, this increased compression limits engine performance with higher boost settings by decreasing the size of the fuel-air charge in the combustion chamber, forcing the ignition timing to retard far below MBT (mean best timing, the theoretical optimal ignition timing). Therefore, the Carbahn B58 engine has 0.5 less compression to optimize the engine for the increased boost.
The CarBahn engine is both stronger and less expensive than the BMW OEM factory engine. The B58 CarBahn engine is designed to improve the strength of your engine if you are tuning your car. Connecting rods are replaced with Carrillo forged racing rods. Pistons are CP forged racing pistons. The engine also comes with lowered compression, ported cylinder head and high-performance valve springs for ultra-high boost pressures. The engine is a complete overhaul with blue printing and balancing. This engine is designed for an increase in torque of 100% over stock.

Valve Spring Kit High Performance Valve Springs | BMW S55, S58, B58 | CarBahn
CarBahn solution
We include high performance valve springs with our engine, however you can purchase the springs separately. Our springs increase valve spring pressure by 20%. We also keep the steel retainers for long term durability.
Steve Dinan has been building racing and high performance road car engines for over 40 years. We are concerned about the trend in high performance valve springs on the new S55, S58 and B58 engines. Companies are selling springs with very high spring rates that will rob power and dramatically increase valve train wear.
Theory
The goal of a valve spring pressure is to make it as low as possible. This is because compressing a spring takes energy and robs potential power. In addition, more valve spring pressure increases valve train wear. We work very hard at running just enough valve spring pressure to keep the follower in contact with the camshaft but no more. If you increase the RPM you increase the valve spring just enough to manage the inertia from the increased RPM. The valve spring also needs enough seat pressure and the correct frequency not to bounce when the valve is closed. This is to avoid leaking trapped mass (the fuel air charge).
Boosted engine
With a boosted engine you will need a slight increase in pressure to push back against the boost pressure in the intake trying to hold the valve open. This amount of pressure added is much less than the pressure to control the inertia of the valve train.
Conclusion
If you double the boost pressure you do not need to double the spring pressure since only about 20% of the spring pressure is to control the boost pressure and 80% is to control the valve train mass. An additional 20% of valve spring pressure is all you need to run.

The concave design of the GA1R not only looks great, but allows plenty of room for caliper clearance and extreme brake fitment, while the one-piece monoblock forging and I-beamed spoke design yield a wheel that is extremely stiff with fatigue strength equal to our proven GA3R. And yet despite the strength and stiffness, for most applications and sizes, it also delivers a high-performance weight reduction – making it perfect for motorsports and racing applications or the discerning street enthusiast who demands the ultimate in performance capability!
The GA1R is designed for racing. It is engineered with a 2100 lb. street-tire load rating (per wheel) to ensure strength and integrity, even when subjected to the massive loads encountered on the stickiest race tires.
The GA1R is produced using our traditional forging method from 6061-T6 aluminum. It is currently available in 18, 19, 20, 21, and 22-inch sizes with a range of widths and offsets. (Please Note: Depending on size, the GA1R may be available in deep, medium, or shallow concave profiles. See sizing chart for details.) And just like any Forgeline wheel, the GA1R is available with fully customizable finish options.
The GA1R is also available for limited applications in Deep Cap (DC) and Extra Deep Cap (EDC) profiles. These Deep Cap profiles employ unique in-house lathe turnings that allow us to position the center cap deep within the center of the wheel and create an exaggerated extra-aggressive concave look. This option is an excellent choice for select vehicles including the BMW M3, Nissan GT-R, ZL1 Camaro, C6 Z06 Corvette (rear only), and certain Porsche models (rear only).
