i was just reading some posts talking about the d max eating up our strokers. my question is why doesn't the cubic inches of the 7.3 blow everyones doors off? mine runs pretty @#$%^& good!!!!!!!!!!!!!!!!!

One reason is that the 7.3 is made up of amny heavy parts, that take a long time to wind up - Awesome for torque, terrible for a race - the DMax has lighter parts, is a smaller motor, has lower compression, etc. Let them win the race solo, then come back with a trailer hooked up!

i hate to say it but the duramax is light years ahead of the 7.3.

-much better injection system with much higher pressures 25k-26k psi compared to 15k-16k psi
-4 valve heads that flow MUCH better than our 2v heads

also it doesnt hurt that they can rev alot higher than us and that they have a 5 speed auto behind them too. btw my old 7.3 puts the hurt on alot of dmaxes

Luke is right. Also luke you can spank those D-max's but you've got a buttload of stuff done to that rig!

They are way ahead - the Duramax is an awesome engine, but it is smaller and made of lighter weight parts, which allows it to rev higher and faster. That is the same reason that the 6.0 is so wicked (when they run).

The 7.3 will always be a pulling monster though(in this case the really heavy motor is great). If I wanted to beat a Dmax in a race, Id pull the stang out the garage.

Yeah, but the stang is kind of cheating lol

[payne5757]

Cheating? Its run what ya brung aint it? lol
