Novi 2000 for 87-93 mustang. Headunit, brackets, pipes etc. Unit spins smooth and easy. These blowers are rated for 970hp and I've seen them make 1000hp. Bigger than the T trim and close to a YSI. Double brackets to prevent flex and double tensioners to prevent belt slippage along with a 10 rib setup. All pulleys, brackets, pipes, lines, bov etc. Great kit
