Default MTI 455 H.O. GTO Hits The Street!
MTI has just finished it's first GTO with a new Prototype engine. The displacement is 455 cubic inches using a Darton MID block. Final rear wheel #'s are 519 rwhp and 527 rwtq. Baseline stock numbers were 291 rwhp and 308 rwtq. That is a 227 rwhp increase! Needless to say, this car is amazing.

Oh, BTW, this is through ceramic cats and a very small cam...

More info & pics to come!

I like the motor...very appropriate for the new GTO. Now it's time for somebody to make a Super Duty Trans Am!

UPDATE!

Let car cool down as the orginal 519 rwhp was after numerous runs. After 30 minute cool down car made 535 rwhp and 543 rwtq!

This is one amazing GTO!

Awesome...can you give a few rough specs (or exact) on the cam, heads, compression, etc.? Also, what size rear wheels & tires? Good luck and take care.

That is INSANE.

Please post more information and prices when it becomes available. I had Conley's in Houston build my Grand National this past winter. I would not be opposed to having a tuner (especially in the Houston area) build my GTO when I buy it.

I am convinced that MTI is the best newage GM tuners in the US. Keep it up guys. Watch out SLP and LPE and L.A.P.D.
