807 HP, single turbo 3rd gen.

[chrleb1]

I saw it make the run. Looks like a Hy35 turbo.

:-laf :-laf That little turbo would be crying so bad. :{

I wonder what egt you would see at 800hp through a 35class turbo!! Still 800 hp out of any streetable vehicle is pretty bada**.

Say 2500 degrees! 1600-1700 on my truck!

well on this truck it never gets over 1350 unless the rail pressure drops and the duration gets too long then it will sky rocket. 1350 is the max i want to take it on this head. If i had the 04. 5 head then it wouldn't matter. Piers said that he has seen a bunch of 03 and early 04 heads drop valves when the egt's stayed above 1300. I try to keep the power around 450 on the street. It will jump up to 700 if i switch it up and 800 with the NOS. I still have the 10. 5 diff in the back, so i'm a little scared of too much power (heavy footed). The Cali trucks with the 235 HP engines got the 10. 5 diffs. When i tub the truck i'm thinking about getting a new diff to stick under it. I'm not sure if i should go Dana 80, 11. 5, or a 9 in with some 41 splined axles, or what. I'd like to keep it streetable with a non spool type posi. any thoughts would be great

Wheres Riverdale from San Diego?

5 hrs North of you, ... take 405 to 5 to 41. I'm south of Fresno 30 mins. Don't blink or you'll miss it.

I love my old 12V, but there are so many more options with the common rail. I'm gonna start to pull the 12V out of my big 99 truck and stick in this common rail i picked up the other day. Its just so easier to go from 400 HP to 800 HP in a common rail. No smoke, no turbo lag, drive any where any distance without worry, ... . yah i'm happy.

I knew this talk would come out sooner or later. As great as the 12V is the computerized version will give you far more options.

Awesome! Looks like the duramax will be left in the dust by the common rail Cummins pretty soon and the Fords will be :{ .

Good job guys!

Your close to my boat brothers in the Navy! Do you get tired of the fog and chemicals. I like that area for the Farming, yep I did that before joining the Navy back in 91'... ... hard times but loved working for myself.

And with that big ol turbo? Heck, my 66mm is a little slow with only the 400hp setting, I will be eager to know about this turbo you run and its street manners

 

[Reb.B]

well, come on over to MM '06 and drive the truck for yourself. Only thing i'm scared about is driving in high elevation. It runs at real low boost cruising. Its about 2-4 psi boost at 2300 rpm at 80 mph. But it gets it on though.

Hey Jim, the fog is bad here, but the chemicals are overrated. They won't even let us burn any more. We farm about 500 acres(almonds, alfalfa, pecans, wine grapes) here in the valley and own 5000 acres of cattle land up in the hills near Colainga. I hear your navy seal brothers all the time at the range near Coalinga. I think its the last 1000 yard range in California.

Oh, on the turbo again. I was really scared when i first put it on because my wife wanted to drive it and she likes power. I never leave the TST box on, so i wanted to see how it felt with no TST, ... . it is perfect, feels like a stock truck, but more power. I am so amazed at this turbo. This same turbo on my bros. 12v truck was aweful. It would not get out of its tracks. Thats what really led me to understand the differences between the 12v and common rail. The common rail has the unique ability to spin turbos. Since then, i upped the size of the exhaust housing. The vender didn't want to sell me it, saying it wouldn't spool. Again i was scared, . . i thought now i had crossed the line between driver and dyno queen. Well i did the transmission at the same time. I took it for a test drive and it was snappier that the orginal set-up. I was in shock. Before it would take longer to run hard and it would not break tire loose without the lock-up, but now it does it faster and without lock up. This is with no water or NOS and other boxes at medium settings. I leave those for the dyno and the track. Also this truck is a 4 door short bed two wheel drive. I would be scared selling a customer one on these turbos on a 4 door long bed dually 4x4.

How do you keep rail pressure high enough?



I just installed a set of E. D. M's I got through Greg at greatlakesdieselworks/LSFarms. They help spool-up a whole bunch and with TST on 1/1 or 2/2 they run cooler than stock injectors at similar seat of pants feel (lots more smoke though, at any TST setting). However, when the TST is turned up to 3hp/any trq setting the egt goes through the roof. For example TST at 4/4 and egt went to 1750deg real fast (the truck didn't feel much stronger than w/TST at 2/2 either yet 450deg warmer).



I suspect rail pressure (guage is on the way) just nose dives and the ecm compensates with duration. Given that the TST is already increasing duration pressure drops even faster and you end up shooting a bunch of low pressure fuel way too late. Just my uneducated opinion.



What do you gents suggest?

What size injectors? How many holes, what size? I ran a set of edm's more than likely from the same place that Greg gets his here in Michigan.

 

[Digger]

What were your numbers with just #2? No power adders?



Congrats



digger

Was the truck not dynoed with just number 2?????????

 

[Reb.B]

i dynoed 700 with no nos. I dynoed a month ago at 634 no nos or water/meth. I was 40 HP more this time across the board and i gain a little more with less duration this time, so i guess around 660 or so. I need more testing. The other day i was last and we were all in a hurry to hit the basque for picon punch. I just wanted over 800 this time. With some additonal testing, pressure improvements and better NOS programming i'm hoping for some really big numbers. The best thing is that i have so much more potencial.

I've run up to 4x4 w/ TST "twins, MP8~40%, and 100 HP 3-flow injectors. It's a bit smoky on the low end w/ low boost, but clears up quick. Similarly, on low boost EGT will hit about 1400* and then settle down to 1200* and then I run out of road and speedometer. Rail pressure IIRC hit about 14,000 psi. I figure that's about close to the limit before the pressure becomes useless except for heat generation.



If you want, I can go out when the roads get clear and do some "tests" :-laf

 

[RChamberlain]

where is the vids cus that is bad

 

[bgilbert]

I need to go out west for a big number :-laf . .

Those are great numbers. What type of boost/drive pressures are you seeing?



Thanks

 

[Reb.B]

62 psi boost. No idea what the drive pressure is, but i'm sure its not too high. Drive pressure is a real killer of horsepower. The head is studded. When i upped the size of the exhaust housing i was hoping to lower the psi boost but with the extra NOS it shot right back up. I'd like to keep the boost around 58 or so. Street driving at 454 HP it goes to about 40 when i hammer it. Thats what i like. A common rail needs less boost to ignite the diesel in my opinion. Joe D. was making 600-800 HP with 55-60 PSI boost. I think that with the studs, the rigidity of the common rail block, and the better common rail gasket that 60 psi boost should be okay.

 

[dan shss]

Congrats Reb,,,What boxes were you running and what settings? And is the inducer size on the turbo bigger than 2. 8" . . I forgot to ask you when we were in Chatsworth at that awsome dyno event

Maybe i wil run one of your little turbo's for next 2006 pulling seasons if it meets the 2. 8" rule. .
