GDP Intake Horn Tested!
 

OK folks, finally got a GDP test completed. JP volunteered his truck and the results were pretty solid. The full article is available on our site (FINALLY back up) at : http://trivalleyperformance.com/inde...d=19&Itemid=51

The short of it is that it makes almost as much as the CFM+, is not plastic, has brackets for the GDP filter kits or for custom nitrous solenoid brackets, etc, and comes in cool colors. All for less than the other intake horns on the market.[guitar]

sweet ... thanks for the results Erik!!! very much appreciated!

Thanx so much for doing this & sharing the info!

THANKS ALOT ERIK. now i have to spend more money! dang it! LOL

My pleasure! I think the folks from BD are sending one down for me to test on my truck, so we should soon be able to add that one to the pile.

Please feel free to suggest other products to test, we'll keep doing them as we have time!

I also have a GDP intake on the way for flow testing :cool:
Between flow #s and dynos we get to see the big picture.

Erik,

You need another tester at 5000ft base altitude let me know!! LOL

Excellent!!

Am I reading that graph correctly? The green lines are the new hp and torque with the GDP intake? The intake smoothed out those huge dips in hp and torque?

Andy

Haha, well the dyno is a little tough to travel with!

ahh, that dip was a slip on the throttle from JP, NOT a prob with the stock manifold. The Green is the new graph.

oh, got that cured, there is one in town! lol... [coffee]

Then how can your comparison be valid? You claim 136 lb-ft more at 2000rpm. Is that the fuzzy math I hear about from Washington all the time?

Andy

Easy, the dip was pretty much over by 2000rpm, you can draw a line to approximate the power curve without the dip. Even discounting the dip, the power gains elsewhere were consistent. Boost when the run started was the same for both runs and they finished approximately the same also (44ish psi)

it would have been 70/190 if we counted the dip!
