New '03+ twins

[Mark_Kendrick]

Sorry for the poor quality pictures. They're off my camera phone. I have some good installed pictures being taken (hopefully) Friday.



These went on Craig Monroe's (Cmonroe) truck.



The truck is an '04 SO Automatic with ~100hp injectors and an EZ. The fab work was a bit fun but there were no real major obstacles. The truck is seeing marginally better if no the same fuel mileage after 1000+mi. cruising EGTs are 550* at 80+mph (running from OKC to denver generally uphill). Max boost has been 54 psi with a 58psi spike on the OD shift. Craig will add a boost controller this weekend to dial bak overall boost into the upper 40's. He's getting an ATS transmission this week or next so we'll see how they take some real abuse soon.



Thanks,

Mark Kendrick

Mark, I see you chose to use the stock (stock shape, probably an ATS copy) exhaust manifold. This would move the top charger forward and up quite a lot from other systems I've seen. Any comments as to how that worked out for you... . better, worse, indiffrent. Thanks. Also, what model is the external wastegate?

[Mark_Kendrick]

The mockup is a stock manifold. I tested it for fit on an ATS.

I generally use a turbonetics wastegate, usually an Evolution or deltagate. this one is a Tial. The turbonetics gate was back ordered.



The whole Idea is to keep the kit affordable. A new manifold is over $400, Extra turbos are expensive. I choose to keep the stock turbo and use a large externel gate.



the kit us upgradable to the B1-03/04 as a boltup. The big turbo is a B2 and starts to build boost beloww 1500rpm. It spools faster and flows better than the BHT3B. The opposite scroll of the 3B would have been easier to fab but the design headroom given by the B2 is definitely worth the effort.



A blip of the throttle at 1200 rpm lets you hear the big guy turning and by 1500 rpm the deep WHIRRR of the big turbo is really appearant



Craig seems to be nothing but

If you used a B1-04 in this setup, what would the cost be for the B2, piping, etc. if I already had a B1-04? Would you still need the external wastegate?

 

[Mark_Kendrick]

The external gate is mandatory with any twins setup to use a quick spooling secondary(little) turbo. It corrects the flow deficiency of the little charger at high load and/or rpm. The kit prices assume using your top charger and manifold.



Feel free to call me for pricing. 817 343 8666.



Thanks,

Thanks for the info Mark. I PM'ed you with some more specific questions.

[OT-OF-HERE!!]

Mark,..this is meant constructively

Cost savings is a good thing, but when we pop our hoods to show off our twins appearance is an issue. The welding in your photos is lacking. Also the piping needs upgrading. They need to look as good as they are. I love the turbo selections but purtty is part of the package. Just needs a little touching up and you've got something.

Check out the final pics. (above)



THESE WERE PROTOTYPES!!!



Those tubes came apart 4 times to ensure everything fit and all the oil lines and drains were accessable.



Here is more typical work... #ad

I am getting ready to do compounds and i am going to use an HT60 for the the bottom turbo any thouts on how it will work with that turbo on there. I am waiting for ATS to get the piping from texasdieselworks.

 

[TCDiesel]

Alright you got My attention, will the setup use stock exhaust the reason I ask is I do not want to give up My direct Mount EB.

Check out my signature :-laf I'll be making them this weekend. I'm pretty sure youre gonna do some rework to make it fit in place of a B2.



The current version of the HT60 is the HX60... http://www.holset.co.uk/files/2_1_1_5-HX60.php



The HT is similarly sized with the B2 but scrolls opposite (like the HX35) and will likely have a different flange bolt pattern.



FWIW,

Mark

direct mount? in the pipe or hanging off the turbo?



in the pipe is easy to relocate. on the turbo will cost a few $$$. it'd be totally custom but I bet I could make it work.



later,

Mark

Mike At ATS is going to rework the kit it to fit that tubo.

 

[Mark_Kendrick]

How about I bring the parts and we just build it right to begin with?

I'll be in early the 11th at ATS... We'll just give a class in twin building. if you're up to it



I'm not kidding. ATS has a tig and a mig, and I'll bet a chop saw. I'll bring the rest and prefab the stuff that will work. I bet I can final fit and weld them in a day. . I've had a LOT of practice lately.



You up for it?



on edit: I'll ask Clint and Mike if they'll allow it. If they will I'll bring my work clothes, few tools I can't live without, and we'll build and install them for the dyno day on Sunday. I bet we can round up enough spare hands for a PROPER B. O. M. B. ing party

Mark do you do budget twins setups for 12-valve 2nd Gens utilizing the stock turbo? The small '03 & '04 turbo would probably give better drivability with quicker spool. I am in the process of buying a used DD Jammer, I wonder how well that would work with a '03 turbo as a twins setup?



I'm thinking of the "what ifs" since I have no plans to go twins. Going to stick with single and mid 300s HP.

[Mark_Kendrick]

You can take my STD 94-02 kit and use any of the following: HY30-9,HX35w-12/14, or add a 40 compressor( dodgezilla, nasty nine, etc)



The hy's are good to 550 or so HP. 35s can be pushed to 700 but are really good to 640+/-.



I have not built a kit for a 94-02 using an 03+ turbo. Not a lot of demand for that





Thanks,

Mark

Mark, I talked to you a few months ago on the phone, (The one who told you about turboed snowmoblies, and the truck from cali you were going to make your twin kit jigs if I drove down). Anyway, My plans then were to get a B1-04 then with the stocker off build the twins piping from there, my question to you is that there is a slight diffrence in length (about an inch) If I were to get your kit could there be enough room to stuff the B1 in place of the stock HY without extra fab work? Or should it go in?

 

[Mark_Kendrick]

There shouldn't be an issue if you have the B1-03 or 04. I build a a bit of a gap just for that purpose.



The primary upgrade path for this setup is a lager compressor for the HY and/or a B1.



Thanks,

Mark Kendrick

 

[mattymac]

On Craigs truck is it a B1 or the stocker? have you done any mods to the head to keep it from lifting? I have heard that the 3rd gens can take a few more lbs than the older 24v's, Is that why he will be dialing it in to the upper 40 lb range?

 

[Mark_Kendrick]

Craig is using the STOCK 2004 turbo.



I've been told that the ISBe headgasket is decidedly superior to the ISB gasket. It's not uncommon to see a stock gasket live well into the 60# range.



I was talking about dialing it DOWN into the 40# range from 58#. his WOT EGTs are 1050* with 100hp injectors and an EZ. Down from ~1450. Afull 400* drop but he's making too much boost for that HP level. I'd like to see it at 45# or so, then he should see a healthy 1150-1250* preturbo EGT reading. If not we'll adjust accordingly.



Thanks,

Mark
