I am never satisfied...if i can sell my 98mm borg, it would be tough to decide between the gt5541r or a set of triples. Triples was my original idea but then I got this borg s500sx for a screaming deal.

I really do like this borg alot though. I just like to switch things up.

I figured I'm on my second set of compounds . I'm like Mike never totally satisfied and wanting the next best thing . I was thinking triples last time I put it together . I'm a bit more hell bent on triples on this current build .

I think it depends on what you are going to use your truck for. I really don't see any advantage for the strip, especially for a dedicated race truck as you spool in the line, and compounds normally weigh less and are less things to go wrong. Street maybe, spool better and at the smaller setups I'm sure they flow better as well.

I'm after awesome street manners , quick spool up on the street but same over all performance as a large set of compounds . 1200-1400 RWHP . Current setup has no real boost rolling down the road . I figure with smaller turbos there should be 5# or more rolling down the road say at 1800-2000 rpm. Close if not better than the DP 72 VVT /S483 compound setup I had previously .

I only see 2-3 psi cruising at those rpm. Just doesn't make boost much at cruise speeds. Maybe if you went with a smaller primary than a 475.

How do they spool from 55mph 5th gear with converter locked up?

With no downshift....I think you know the answer to that. Slow.

As long as I'm "allowed" to downshift, it spools just fine all day. But for the secondary being a 75/87/1.0, I'd say it does pretty well in the spool department.

I am contemplating either going with a 94mm or a 104mm to go with my DP 72mm thats in the valley or I am also considering going to triples. Keeping the 72mm in the valley and adding at least 2 66s possibly bigger. I have not had a chance to discuss with Mark at Danville yet. I'm curious which setup comes in quicker and which has the most readily available instant power . Which turbos you use , dyno info, track times etc. Any info you guys can give me will be greatly appreciated.

I'm on set #4 now. First two were compounds......a 475/stock on a stock engine, then a 480/366 on a built engine. Then two sets of triples...62's/HTT366 which was changed to 371. Now it's gtx4088's/468. The compounds drove really beautifully and were nicely responsive. The first triples were extremely responsive and snappy. Current set is all T4 with atmospheres that push lots of air....makes more power but a bit less snappy than the first set. It's still very responsive though, and there's more tweeking to be done. Trouble with compounds as I see it is when they start getting big and with a large atmosphere, piping is big and takes up a lot of space..... things get cramped in there for the A/C. With triples two smaller atmospheres flow the same or more air than one large and spool a lot quicker. For drag racing that doesn't matter. Mine is a daily driver at altitude. The downside to triples as I see it, besides cost, is space. Two turbos and a lot more piping are crammed into not much space. Things get real crowded and hard to access. Not so easy to do something like this and have reasonable access to everything and not crowd the A/C. But I've been happy with how triples drive and like them a lot.

Heat too. Triples have a LOT of heat focused in one area. Although with a Duramax you have the secondary sitting in the middle, where on my Dodge all three are in one place, so may not be as much of an issue on your truck?

The space and heat were things not mentioned to me (or I just didn't listen) when I got mine. I mean I knew about the space, but didn't think about the SPACE and how things were routed and such.

I've battled melted AC lines, melted wires, and melted coolant lines. Again, on a Dodge and not a GM so may very well be different/non-issue.
