I don't doubt they will extend the life of a drive in rougher conditions, I think the issue most people will have is removing the engine($) to install and the purchase price of the part($) DG.

If I had a race team and had DG as a sponsor I'd be running and praising them too!

I don't know if addressed it, but when they first came out I don't believe the fit inside the merc dual cooler housings iirc

Have you seen the other thread where Saris has before and after pictures of their gears?

That`s what I run, those fitment issues have now all been solved.

I have to pull one of my motors for a rear main seal anyway so I just ordered 2 bravo units. Hopefully they will be a good return on my $$$

True to an extent... However on the flip side, they wouldnt be continuing to praise(almost 2 years now) it if it didnt work.. they would sweep it under the rug and just not mention it... Rich and Johnny have come on here time and time again praising the product so I would have to lean towards it working..

I asked Ernie Dupois at the Borden Light Poker Run what he thought of the Drive Guardian. He spoke very highly of it, didn't have a bad thing to say about it. To the best of my knowledge he is running 900 horsepower through a bravo based drive in a 31 foot single engine Sutphen.

That's good to know. I was thinking of getting them when they first came out but they wouldn't fit at the time. I figure with the mild power I have I'd never give drives another thought.

We love ours, wouldnt run hard without them. We're happy to answer any questions. As Trent stated, if it didnt work, we wouldnt use it. Our before and after gear pictures tell the whole story. Not to mention the list of other teams using them. Stihl, Smith Brothers, Cat Can Do, Perdition, Boxer and there is some MDC Technology on the Spirit of Qatar Mystic.

Nice to hear from someone that uses one and successfully puts that kind of power through a bravo set up.
