MSV Racing’s 89’-01’ Honda CR500 Billet HIGH FLOW 7° Elbow – Unmatched Cooling Performance!
At MSV Racing, we constantly strive to push the boundaries of performance, and our Billet HIGH FLOW 7° Elbow for the 89’-01’ Honda CR500 is no exception. Through advanced Computational Fluid Dynamics (CFD) analysis, we achieved a +1 PSI backpressure reduction, while flow bench testing showed a .954 AVG GPM increase in coolant flow compared to OEM and replica models.
Why Does the MSV Racing 7° Elbow Outperform OEM and Replicas?
– Precision-Designed for Maximum Flow & Efficiency
- Fully Radiused Interior Profile – Unlike OEM elbows with sharp 90° turns and minor fillets, our 7° elbow features a fully radiused interior, providing dramatically smoother flow, relieving backpressure, and reducing aeration.
–Corrected Coolant Port Alignment
- The 7° elbow outlet port is perfectly aligned with the cylinder inlet, eliminating the misalignment issues found in OEM elbows. This reduces turbulence and aeration, ensuring clean, efficient coolant flow to keep temperatures stable.
–Optimized for H₂O Pump Efficiency
- Our 7° elbow inlet spigot is pivoted to point directly at the H₂O pump’s discharge port, unlike OEM and billet replicas that fail to align correctly. This enhancement boosts cooling system efficiency, ensuring better overall engine temperature regulation.
–Tapered Lead-In Profile for Superior Flow
- We engineered a 6mm, 3° tapered lead-in profile on the spigot instead of a square-edged design, maintaining smooth laminar flow as coolant transitions from hose to elbow inlet. This further reduces turbulence, aeration, and backpressure, enhancing reliability under extreme conditions.

Quality part. Looks great. Easy install.
Joe Miltenberger (verified owner) –
Fitment was perfect
Rob Roberts (store manager) –
We went with the elbow first because we could tell the design was far better than OEM and wanted to see what the supposed added flow/reduced back PSI would actually provide. With OEM impeller we saw -6*F cooler at the track!
Richard M. (verified owner) –
Probably will never know if it works better than the stock elbow, but it looks cool and fit like its supposed to.

perfect item!

I love this parts cnc

nice product, price is fair, was too expensive before.

I installed the impeller and GEN II high flow elbow on my outlaw kart. Jason said most kart racers are seeing 10*f cooler with the impeller alone and not sure what additional cooling the high flow elbow will provide. At the track I saw 20*f cooler running! Reducing the back pressure on the impeller really helped! We will now start leaning the jetting to pick up even more power.
