Comparing the 9-Plus Race case (right) with its grey iron stock counterpart is illuminating. The higher quality iron and larger ribs allow this race case to handle up to 900 hp, while the stocker can only survive up to the 300hp level. The cost of upgrading from a stock case to the 9-Plus Street case, which can handle up to 500 hp, is about $120. Or you can opt to upgrade to the Race case, as we did, for an additional $120 over the Street case.
