Twins

[RCC]

It comes with powder coated plumbing,ht3b turbo,down pipe,all the boots,and all the clamps,nuts,bolts,gaskets,and oil drains. It is a complete package.

Sounds like Mark kendrick's system



But save some coin

Their kit looks to be well made but...



the reason for the difference in price is they do not use an external gate. I also use a TAD-B2 that extends the kit to 700hp or so.



I won't sell a set of twins without an external gate. the draive pressures above 50psi become a real problem.



the drive pressures with a 38mm gate should remain a hair below 1:1 until 60 psi and don't become an issue until 70-75 psi.



The external gates are a lot more adjustable and yield higher eGT reductions under load. the higher flow makes a big difference on the top end.



FWIW,

Mark

I don't powder coat unless a customer requests it. Most prefer ceramicoating... way more expensive but worth it.



My kits include all of the harware and plumbing too, to include a 5" downpipe.

I like the idea of external waste gates but i do not think that they are needed yet on the 3rd gens. I would really like to see any 3rd gen approaching the 700hp mark.

I know Piers made 735HP w/his twins. BUT they will NOT fit w/the KORE suspension-shock towers get in the way.



I guess the real question is will anyone else's fit w/KORE???

Your kit seems to be similar to Poole's kit (cheaper) for people who already have a B-1. What's the difference?

The common rail motors do not produce enough fuel to run a hx40 up top. So the relentless twins use your factory turbo . It saves on cost and its all we really need.

the common rails can produce enough fuel and now that people know the recipe for the HP there will be plenty in the 650-700 HP range. Piers made 735 HP with the only internal mod being a cam and injectors. And spool up is far from slow with the set up. The thing smokes with just a blip of the throttle

I appreciate everyones opinion. This thread started with someone asking for some help on twin selections and now it seems everyone wants to tear apart what i have to say. I would like to see these 700hp common rails. Where were these horsepower kings at indianapolis . I really want to see one of these at the track because dyno's can be manipulated(i am not saying they are) but the best measure of horsepower is mph in quarter mile. Lets see someone beat a 12. 23 @ 110mph and we can all leave it at that.

We made 619 in 11/02 so 700 should be pretty easy. We will see soon enough! The twins I built were the first ones that Kendrick ever saw and helped with on Common Rail so I would think by now he should have them perfected. The 619 was with a 250hp SO! :--) It had more power than any transmission we could find at the time!

I have the PDR twins and love the performance. It doesn't fit perfectly with the KORE suspension as mentioned. But that is being worked out. The first install didn't work out so well and it's all torn back down again at a shop in TX. Nothing blew apart or cratered just my decision to tighten things up. It'll be nice when she's all back together. It did make 660. 5 hp, after twins install along with injectors and other stuff I already had.

track times can be manipulated just as easy as dyno numbers. The dyno numbers were made on a load dyno by a very reputable person. So it is very unlikely that they are false. Track times have more factors in them than just hp. Anybody can take a lighter vehicle and run faster than the next person. As for 700 hp common rails I only mentioned one! What I said was the 650-700 hp range. Which quite a few have achieved. Just because you haven't seen it or been able to reproduce it doesn't mean it isn't true.

lmills,



Thank you, you made a great point that I forgot to mention. Weight is very important in drag racing. The truck that I'm talking about weighs 7085 lbs. When a truck weighs that much and runs over 110 mph in the 1/4. There is nothing to manipulate. No correction factors, no exaggerations, nothing.



Let's face it none of us will ever agree on which style of dyno is the best or if dyno's are more accurate than sled pulling or racing, etc.



Quarter mile e. t. varies widely and can't be used to predict HP because there are just too many variables. But weight and MPH through the traps is VERY consistant and can't be modified.



If the HP numbers that are being claimed are anywhere near true then ALL of these trucks should be able to match these numbers and even run much faster. So tell me, why hasn't anyone done it?



Until another common rail can run that fast at that weight, I do NOT believe that they are making more power.



None of what I've said is second hand information. I've witnessed it at the track, I've driven it and I've seen it dyno. And by Monday or Tuesday, I expect to be outrunning him.

So MPH through the traps is what determines HP, what MPH do the Haisley and Schied pulling trucks do in the 1/4 mile??



What about me? I am limited by gearing to 105 mph (3125 rpms) - So thats mean no matter how much HP I make (maybe 900. . ) I will NEVER EVER get to 110 mph in the 1/4 mile...



What I am saying is just because a truck can muster up 110mph in the traps, does not mean that truck has more HP

I would like to see these 700hp common rails. Where were these horsepower kings at indianapolis.

I was at IRP and won the dyno competition with a run of 647 hp. The 1/4 mile times in my signature are old (about 100 hp ago!), but they're still faster than your auto truck. If the rain holds off out here in NC I'm going to try to get to the DHRA race and see if I can row this beast to a 12. XX. I'll be happy with a 105 mph trap, too... considering I let off the gas 4 times down the strip :-laf Oh, and I run an HX-40 up top. External WG, too!



John



Edit-- I didn't race, by the way, because I didn't want any freak breakage 12 hours from home.

Little off topic, BUT Banshee - YOU HAVE GOT TO GET SOME VIDEO of you row'in that beast down the 1/4, Cause I bets thats AWESOME

So RCox you are saying you have dynoed 600 HP and your buddy is running 1. 3 seconds faster than you??? Then that would put him around 675 HP easily. What did he do about the the top end limiter? Is he running larger tires? And now you are saying that you will be running faster than him?? So that would put you over 700 HP. Which you are saying is not possible with a third gen. Your kind of contradicting yourself with what you are writing.

 

[blake underwood]

Can you guys start a new thread about this stuff, and let the twins topic continue. It was really helping me out and dispalying some good info. Now w/ this HP & track talk I cannot even get my questions answered from the beginning of the thread.

 

[lmills]

Sorry Blake.

It just doesn't make sense to me to pay $3000+ for a kit that has ONE $500 turbo. Piping and oil lines don't cost $2500. Just my $0. 02

Jeff, as a TDR dude I'm going to let you in on some data, building a set of Twins is a PITA, that's all there is too it. It took me 2+weeks just to find the parts and figure everything out prior to building my first set, the second (and current) was even worse trying to fit that Pig on the bottom and clear the frame, manifold and fire wall, they are no joke the first time and if anyone tells you different there lying. Allot of hours in the first one with trial and error, after that there is just a tiny bit of profit.



I like seeing Chris's name on the board, he's quiet about what is going on but remember we were at the D/FW dyno event together in 03' and I was at 285 and he was 400+... . both with stock turbo's... . FYI!
