Building a 404 and quad range December 08, 2022 01:02PM
What is everyone’s thought on building a 404 for a 430 cube class, will a quad range handle the shift?

What other rules are you working with? Turbo? Weight? Tires? Injection pump? Speed?

With extra clutches and a little extra pressure the 6 bolt planet carrier quad from a 40 series and newer will handle breaking the trans before it gives up.

Which box charger? 3LM, GT42, or ???

Are you looking to have fun and finish respectable or run at the front?

With a 2500 RPM limit you are going to want more stroke. 8.1 crank or more.

Karl at Atlas should be able to set you up with the gears to turn a standard under drive quad into an overdrive with half the step up. The quad should hold up to a GT42, but the wet clutch wont last long, especially at that weight. With a 3LM you should be good.

Which box charger? At 2500 rpm with a 404 I’m going to say wet clutch is going to be fine.what speed are most of your competitors running going down the track?

We run a Raush wet clutch and a modified quad with a 7.6. Don't shift on the go. We broke the input shaft and damaged some gears 2 years ago and did not shift on the go. Running 10,500 Hot and Altered Farm class. Just a heads up if you want Atlas gears get them ordered asap. A guy that pulls with us was running a 466 with a guad and it finally puked. he always shifted on the go. He replaced the quad rear with a 4320 rear with synchro and dry clutch.
I'd say if you're going over the 600hp + range you are playing Russan Roulette.
