Towing with Diamond Eye downpipe
 

I know a Diamond Eye downpipe is more of a :": performance :": product, but how is it's longevity while towing?? To be exact, can it withstand 1200-1400* temps for 4+ hours of constant towing, over and over again??

Oh and can headerwrap sustain that same torture without burning into a big fireball?? :w2:

Just ask'n.... :humm:

didnt you have one of them on ur truck before?

Nope. TxC did.

I might.....now. :w2:

:humm:

Uhh, id sure like to know before I install mine.. Hows yours workin so far Russell?

what is it???

you should keep a fire extinguisher handy, in case it does turn into a big fireball

smelly, like something's burning... :ouch:

The downpipe is the pipe that comes off the turbo and attaches to the front pipe of the exhaust. The stocker is restrictive, the Diamond Eye is nice free flowing.

this been dyno tested yet?

No. I'm just on a quest for the lowest towing EGTs on a Dmax while keeping the cab as quiet as possible. :U:

i cant even tell if ur truck is on its so quiet lol

stil runnin the stock intake with the lbz turbo inlet?

Everything is stock. :hss:

stock parts...

I'm also looking for some info about the diamond eye down pipe. I have a 5" cat back that I'm going to add the cat delete pipe to. I tow a toyhauler and am looking to lower my EGT's also. Would the new down pipe be worth the money?

I got mine because I saw someone elses and saw the flow advantages over the stock downpipe. I like the EGT's I'm at right now but the burning smell worries me. I put my truck in the air yesterday and took a look at everything. No leaks anywhere from the downpipe back, but the downpipe is very very close and almost touching the bulkhead (firewall) insulation. I'm suspecting that's where the burning smell is coming from. Sustaining 1200+* for a long period of time while towing might be a bit too much for that area back there. I'm going to call Diamondeye about it and get their input.

Keep us posted :pca1:

I bought one this week from Alligator Performance and am curious about the burning smell you are talking about. Please let us know what you find out. Thanks! Tony

I haven't called Diamondeye yet, but I did get a good look at everything the otherday. I think what has happened is the downpipe is touching the bulkhead insulation and causing a slight burn. The insulation is nicked due to all the times I removed the stock downpipe to do some other things. I'm going to build a shield to push back the insulation and pertect it from the new downpipe.

I'll take pics and do a 'show and tell' if my theory works. :U:

:pca1:

the smell is normal. it will go away. it is the heat wrap heating up and burning on to the pipe. mine did this for a few days it will go away. and yes it can withstand 1200* to 1400* no problem. the pipe was not just designed for race aplicatons. it was made to lower egts in any application. and you will see about a 200* drop in egt's

Not hardly. Everyone says that about the down pipe, and 100* for the cat delete and 100* for an aftermarket muffler and 50* if you block the EGR, but it's all 'hear-say' and 'watching the guage'. If it was true then my truck would be runing under 1000* EGTs at max load and it doesn't.

Facts are facts and the only way to do it is by dataloging identical runs (and even that is not 100% accurate). I've done a LOT of testing and data loging for EGTs and after everything I've done to my exhaust, I've only dropped ~230* total (pre-turbo reading) at 100% engine load sustained for miles. The down pipe and cat delete are only good for about 50* total under max load conditions. This is what I was expecting and is great in the over all scheam of things, because now my max EGTs are 1230* at 100% load. This is much better than the 1480* it use to be under the same conditions. My goal is 1200 or under, but I think that might be impossible without tampering heavily with the tune. Who knows, I still have a few tricks up my sleeve. :w2:

damn ur all the way down to 1230 now?

thats good considering the stuff you tow and where. so whats next?

I haven't totally tested the LBZ mouthpiece yet, so that's next. From what I've seen unloaded, it's might be good for about 10-20* max at full load.

Then, since I have ECTs and EGTs well under control, a set of TxC's Max electric fans should polish off the truck nicely. :U: I suspect another drop in EGTs (not much though) due to the lack of the fan pully no longer having to drive the clutch fan. I know from previous testing the fan clutch sucks 10hp from the engine at freespin (60hp at full lockup). So if I release that energy, it's all now extra pulling power. :choochoo: Soon I'll be able to out dyno you without any tuning being involved. :tttt::c: :ok1:

RTTOYS, I've been thinking about putting electric fans in my truck and yanking the clutch fan. Let me know how it works i pull a gooseneck everyday and the summers in houston are hot.

oh no you didnt :bat:

:lol88:



Texas Rocket:
Normal electric fans like Flex-A-Lite won't pull the CFMs needed to cool our diesels when towing. TxChristopher has had Spawl make him custom fans (to TxC's specs) to attempt to pull the correct amout of CFMs needed when towing. There is a catch, the electrical needed for these fans are outragous and it will require a dual alternator setup (which I already have). We havn't made a good pull yet with the prototype fans due to the outside temps are too cold, it would be cheeting the test (like a lot of people like to do). I should have these installed (hopefully) by the time I make my normal Bandera run, fully loaded in March. I'll be watching EGTs and of course ECTs, not to mention fuel mileage. :5: I expect great things from these. :U:

dont tell tracy about them big fans, he might freak out again lol

He's been MIA since November. He's not here, doesn't return e-mails or phone calls....:humm: I guess we are just not good enough for him anymore. :ouch:

:humm:

he has been spotted around town. seen him on myspace too.

hey u know anywhere i can find some Kodiak exhaust manifolds?

He works down the street from me, I've sen his truck in the parking lot.......but he doesn't like us anymore. :sadnow:

I thought I saw some Kodiak stuff on CL a while back, but can't find it now. Same with DP. :humm:

I though with the V2 you where fine towing with the damn fan setup? Is the damn fan max a twin or single fan setup? What happend to your header and up pipes I thought those dropped you EGTs a bit?

you see any let me know

Well....the correct legal answer is 'no' you can't tow max capacity with the V2 and Fan Damn, BUT there are quite a few people that do it and do it successfully. Now, Fan Damn Max.....we will see soon. :rocking:

Fan Damn Max is still 2 fans and it all looks the same as the normal Fan Damn, but the motors are much bigger and stronger. One Max fan pulls almost the same CFM as the 2 normal Fan Damn fans. He's also doing what's called Fan Damn HO. Which is one normal fan and one Max fan. Great success so far, from what I've heard.

I still have the headers and up pipes, but due to some recent events with TxC and RDL, I don't talk or give out any more info about them. Period.

My overall EGT and ECT drops are due to ALL the added components I have on my truck. Just the V2 alone I was completly satified with my trucks performance, now it's kind of become a quest to see how low I can get with the ECTs and EGTs and how much power I can increase all without tampering with programming or increasing the noise levels in the cab. :U:

Any idea if there is still a need for duel alts with the Damn fan HO? Does TX have his site up I try it every now and again last I heard he was switching servers?

HO only needs one alt. :U:

His forum is back up. You might have to remove the 'the' though.

Russell is on the same quest as I am, except that I have allowed a little more noise. I went with a Borla exhaust, and it is only slightly louder than stock. We'll soon see how noisey it gets when the cat comes off in the spring.:U:

I'm currently running the Fan Damn twin electric fans, along with the V/2 with fan, and have towed around 10K without a problem. But this was through the midwest; not in the mountains, or 115 degree heat.

Here's my fix for the insulation on the bulkhead (firewall). I'll be testing in 2 weeks, the next time I pull heavy. :U:

I know. I need a picture of it installed. :ph:
