If you enjoying driving your car in on the street and you drive in traffic stay far away from single disc puck style clutches. They are cheep and yes that will hold a lot of power well over 600whp but the drivability on them is horrible. They will make you hate your car. Great for a race car but horrible for a street car. i love love my sos Carbon twin disc. I have made over 650whp with it. It’s rated to over 1000hp and it drive like stock with a soft stock like clutch pedal. Drives easier than an act pressure plate with the stock disc with a way lighter pedal. I drive it in stop and go Los Angeles traffic with ease. If your on a budget and want good drivability you can try the sos 400 clutch and hope for the best but at this power level you really need a twin disc to hold the power and for good drivability.

First pull before adding more fuel pressure. There is another member "soulicious" made 617whp and 442ft/lbs with this clutch and a PTuning kit holding that power just fine. SOS under-rates their clutches sometimes. This is a phenomenal single disc hybrid clutch.

His graph below, mine is underneath. Not a single problem holding that power and very good driveability. No need for a puck clutch at this power level. Over 650whp? Then maybe a twin is needed.
