Edelbrock vs JRSC for track

When it's the most common supercharger, you're also bound to see the most failures. Given how many are out there, the failure rate is low.

For example, rotrex's failure rate is lower than the % of stock FA20 that fail.

Neither has heat soak issues.

That's absolutely possible.

I too have blown a header on stock edelbrock pulley, stock exhaust, Delicious tune during a 20 minute session in New Orleans. It wasn't even a particularly hot day. It was however the 3rd track day I had performed on that setup.

Thank you. I think aftermarket companies like to overlook the fact there's a *lot* of blown F/I motors, even with these two kits. Definitely leads to a lot of misinformation.

Oh, my engine didn't blow, just the header welds, sounded terrible. Had to drive it 3 hours home afterwards, no problems.

Ah, I see missed the "header" part. Well that's good news, good luck with your car.

Stock headers dont like being boosted on track. This is a common failure, when you have an experienced driver that's confident enough to keep their foot on the floor.
