Spicy, Those are some big injectors! How are they while just driving around town, with the box turned down to say 3x3 or so? I wouldn't mind running a huge injector like that as long as it didnt spew black smoke all the time! I like to be able to drive through town with no smoke like when taking off from a stop for example. I am looking at the Mach 4's but maybe I should go bigger.

kipo

what can you expect from mach 2's and htb2 with comp and with or without mad ecm??? what benefits would be had with the same combo with a set of twins? maybe the ones jegs sells? or would mach 4's get closer to the 400-425 range with a single and towing safety; with the comp off????

inquiring minds want to know

Twins give you cooler EGT for a given spoolup, or faster spoolup for a given EGT. There's a point where ONLY twins will cool you down, at least until they design a compressor wheel that's efficient at 75psi.

4s will get you every bit of 425 and then some, lol! Closer to 500 even, when paired with a Comp and HTB2.

The 4s are clean enough that part of me is wishing I tried 5s or 6s

For crusing around town............lol, well box is always off. Since you also have a six speed the best way to take off from a stop sign or light with the injectors I have is to just let the clutch out with no go pedal until you get moving. Walla no smoke or very little. Even at hwy speeds with box on say 5x5 there is no haze till ya push the go pedal, then I look like a frieght train. Sorry to say that I can throw a lot of wasted power out the exhaust, to the point that I can not see behind me.
Just I have been busy building twins for cutomers and I have not had time to do my own. Most of the sets are PDR 40 and a 3B, I am working on a set now that is a HX 35 and B2. So hopefully I can get my own set done soon. Then I hope to cool the EGT's down a bit. I can hit 1600+ no box on by the time I shift into 5th, I know what I have to do to get this corrected, but customers come first. My poor HX 35 with a little bigger exhaust housing hits 43 psi of hot worthless air, and that is about 70 psi of head pressure........so I normally take it easy with the go pedal. Actually I take it easy most of the time, well maybe..........lol.

My Truck
A little white smoke
The aftermath..........
Second gear take off no box on and you can see the shift into 3rd, that would be the faded set, the darker set is a 3rd gear brake and go.
Things I shouldn't be doing, well I have a lot of land, so what do you expect?

The thrid pic you can see the gravel from my driveway, but look and you will see a tire clean spin, and then go. Later Jim.

I gotta be close.... I'm lookin to dyno it with in a month or so. First I need to get a clutch, slippin bad in 5th and 6th. Ill post with results

CTD_Neil

Hey Casmokin, What do you expect to put down when you dyno? What brand of injectors are your 175's?

Hello
I have a strong running stock truck. 427 HP and 927 Torque on numerious Dyno jet dynos and 413 hp on a Mustang.

I have EDMs 2 along with a HX 35/40 turbo a edge EZ and a TST box ( not much good on a HO motor)

I also have a South bend Clutch ConOFE. I am at the limit of the clutch.

Like I say in my sig I have a strong running stock truck.

See Ya

Hello again
I also pull a 5th wheel camper 10/11,ooo lbs and a goose neck trailer up to 20,000 lbs with this truck. I did not have any trouble pulling the West Va turnpike loaded at 19,000 lbs. EGTs where not a problem
I work this truck.
See Ya

Anyone have any idea what I am running for hp and tq? I really wish I could find a dyno in my area. Right now I just have the 100hp nozzles and a van aaken smartbox r, but I am curious how close I am to the 400hp mark. If I had to guess I would say I am around 350hp and 650 tq. TIA

P.S. I know I dont have an ETH but I am still curious how much I am putting to the ground.

HOHN

If your injectors give you an honest 100hp, then you are probably closer to 375hp, 870+lb-ft.

By comparison, an HO with a timing box and 75hp injectors will dyno right around 350hp, 850lb-ft. You should have a little more than that, if you have the air for it.

Joe come on up to our dyno day in MN on Oct 22nd , only about 1 1/2 hours. from you.

CTD_Neil

any other 400+ combos out of an H.O?

diesel_burner

i have the mach's and comp with the con fe clutch bhaf and dynoed at 421/941. and that had the truck running out of fuel. so fass is next should add a little more power. but this combo will pull 80,000 pounds as i found out last night. oh yeah it was dynoed before the lift.

CTD_Neil

Hey Diesel, was that on a Dynojet dyno? Thanks
