I emailed back and forth quite a bit with Justin, great customer service. You can find his dyno runs on youtube as well.
I am sure his CS is top shelf, he's working hard to develop some quality products that enhance the very HI performance side of these engines.
Many here are quite familiar with his products and what work he's done with the IDI.
I applaud his efforts and wish him the best of success in his endeavor.
If I had a built engine that was capable of 100+ CC use of fuel I would very much consider his hybrid pump.
His cam is well done makes terrific top end power and does indeed bleed of some comp to allow for a higher boost level.
Having watched his build and the other Justin's build I tip my hat at both of them.
There is no need for this thread to turn into a R&D vs Conestoga thread. They in my NOT so humble opinion two different offerings.
Mel has developed a great product for us all that has many miles on the MOOSE / BABY product lines, and happy customers and provides a decent improvement in HP and drive-ability.
Russ has a great cam that works well for our engines for a broad torque curve and provides a decent improvement in HP and drive-ability.
Now Justin is going for the significantly higher HP/TQ levels and as these pumps are purchased longevity and consistency will show up. I don't feel it's right to complain about something that he has created without actually having run it myself, however others may disagree.
So if you are planning one hell of a build that will attain significant HP/TQ levels then I'd advise getting in close with R&D and if your looking at stock or mild improvements, then Russ, Mel, and Justin can help....
There is no reason we cannot all use any combination of these 3 peoples products in our engines/trucks and not all get along! I'm quite tired of the bantering that has gone on.
Remember guys....
What Would Jesus Do....
Lets all work to broaden the IDI knowledge base, improve economy and performance and reliability, all the while being open minded to change and new ideas!
