Compounds!

[Ronniemx3]

Who here runs compounds?? I'm looking for reviews on pipe kits or complete kits for s300 over s400 set up. 

 

Also injector sizes.

 

Any reviews much appreciated. CCP seem to be able to supply a kit for good money but I've heard a lot of horror stories about ordering from them! 

 

Thanks

@TFaoro would be one that I know has them. Trying to remember all the names that have twins.

I used stainlessdiesel 2G piping kit https://www.stainlessdiesel.com/index.php?route=product/product&path=43&product_id=76.

BW S362/65/14 or S475/96/1.10

This was my 95 12v so I used 5x.016 injectors.

I run a compound kit by DPS (Diesel Power Source)...a 62/65/12 over s475/96/1.10 and a 3 piece manifold.  Current injectors are 7x.010 but I will be going bigger in the future.  Also run a Smarty/TST Comp stack that will dump the fuel.

 

I did a lot of research before I bought them and they had very good reviews.  My personal experience was a very straightforward install with excellent directional literature and no nightmares.  Shipping was immediate and timely.  I called them a few times during the installation and they answered all my questions and offered tips and advice on things I didn't think to ask.  The kit was turnkey complete...included the high flow air filter, heavy-duty boots and clamps, the downpipe and everything in between...even the 3 piece exhaust manifold, manifold gaskets and fiberglass wrapping for the elbow.  Nothing else was needed to install and no parts were left out of the kit.  Installation was very laborious but not difficult.  Took me 3 days (6-8 hours/day) but I also did headstuds, intake horn, valve adjustments, heat exchanger delete, trans line rerouting, coolant line rerouting, coolant change, 5" exhaust and oil/filter change all at the same time.  If I had to do it over again I would have built the entire system outside the truck and drop it in as one assembly.  Kind of a pain in the arse to build it as directed on the engine due to limited work space/access and the general weight of the parts.  After clocking the turbos and all other adjustments everything fit perfectly...nothing rubs or contacts anything that it shouldn't and both turbos are solidly mounted.  Downpipe fit perfectly too.  Batteries stay in the stock location.  It's a well engineered kit. 

 

Under daily driving conditions it spools and drives just like stock...you would never know they were in there unless you mashed it.  On hard accel boost comes on hard and fast but linear and consistent...transition between turbos is seamless.  I've seen right at 60psi with my 7x.010's and TST juiced up but you'll see up to 70-75psi with bigger injectors and a competent fueling module...but they are wastegate adjustable down to 50psi max.  EGT's now are a non-issue...1100-1150 is the most I've seen.  I only tow a bass boat...mostly use the truck as a fast play toy.  I've had zero issues since install...have about 10k on them.  I paid $3200 or $3400 for the entire kit but I think it's up to $3600+ now...unless you get the bigger ones which are a 364 and 480 for $4000+.  They are a lot of fun and you will be able to hear them.

@Bullet well what a review I'm pretty much sold! ? Im going to go on  their site and pray they can ship a kit to the UK ? I already have an s300 based small turbo similar specs to yours so hopefully that should save some money. Also what kind of waste gate is fitted to your manifold charger if you don't mind me asking? Thanks ??

No problem...they do also offer stocker over s475 kits as well that are cheaper since you already have the smaller turbo...like your situation.  I want to say around $2700-2900.  The only wastegate is a diaphragm style on the 362 that tubes into the s475.  So the wastegate reads the s475 pressure and gradually decreases flow to the 362 as the 475 spools up.  The 475 is not wastgated. 

 

Do a web search on DPS twins or compounds and you'll see others experiences as well.   PM me your email address and I'll send you pics of my setup.
