I have had no problems with mine and did not dyno test but I did notice a signifigant boost drop wich tells me my stock one had to much restriction. I actually thought I had a boost leak on install because boost pressure droped so much. After pressure testing the whole system & finding no leaks I was happy to get rid of the factory restriction. The cast tanks dont look as nice as the welded tanks but nothing on my truck is there for looks all function.

I like the idea of having internal supports to prevent ballooning and eventual failure of the end tanks and I really like your extruded tube open design but have you done any calcs/PC modeling (CFD) or testing with regards to fatigue on or airflow around those cast internal supports? I would hate to have one break apart or break loose and enter my intake due to fatigue and/or aero flow loading. The shape (cross-section) of the supports does not appear to be very aero-friendly as well so they may cause drag (which adds heat) due to the air flow around them and when exposed to high temperatures they will be much weaker in strength. What material is your tank made from? Probably a cast A380 or similar. Note that simple cylinder shaped struts on low speed airplanes caused a ton of drag and were replaced by more aero friendly shapes a long time ago. Just something to consider from a long term perspective.

I am very interested in this product so any help with answering my questions is greatly appreciated.

Thanks!

I appreciate your interest in our products...

You have to remember this is a turbo charged system not a naturally aspirated system so flow and minor restrictions are not such issue. Once the cooler reaches maximum static pressure flow is not as important. The amount of force it would take to snap one of those posts off is tremendous.. even with heat playing a role. The stress that the posts sees from air flow is very minimal compared to an aircraft... I assure you your concerns are not an issue!

Will it fit an LBZ?
Not yet, we are looking at the fall for a release date.

Dave what are these units rated to? When my motors back it's going to 70 psi and I know the stocker ain't gonna hold it. Well this one? And do they fit LMM?
We have tested them up to 100PSI with no issues but it is difficult to test under driving conditions of a 100PSI truck. I would be more comfortable saying 80PSI with heat in the equation. I have seen them on a Cummins application close to that with issues at all.

Whats the pricing on these?
$1399.00 less 5% forum discount, this can be honored by selected BD distributors.

Hope this helps!
