95' Junker Drag Truck

how hot are your egts at the end of your dyno run and or you 1/4 mile. Also are your fuel pressures down or is the cam just becoming a huge limiter in the pump. Over all this is still very impressive with the money you have in this build. Hope you figure you boot problem out.
 
Damn man. I'm starting to wonder about my silicone intakes 30* piece. I think i'm having an issue there and with the mis alignment of the cummins s400 elbow and the hi location the steed manifold places the turbo at.

You are really making some progression with this truck, very very impressive. If you care to at all scurry on over to blacksdiesel and have a look at those pinion brakes still think they would help you tremendously. Great job thus far!
 
Did adding those clicks to the govenor Pick up some mph from Phoenix? I actually backed mine off and ran the same mph in Vegas. I know my truck is laying over HARD with this 160 pump at 26 psi (it's holding better fuel pressure than in Vegas 19psi) I think, mine and your next major upgrade would be to find a pump with a better cam profile... I've already started looking.

You need more fuel! Your cleaning up pretty good with those twins. Congrats on the new best! Roll bar time!!
 
Heck yes! You are asking a lot of 3 and 12 dollar boots... Especially with discharge temps like that! I would imagine the temperature of your 351 compressor cover had something to do with the loss of that guy.. Nicely done otherwise..

I don't have an EGT gauge on the Junker Drag Truck, I'll bet they aren't bad considering the large air setup vs declining fuel delivery in the upper RPM range.

Fuel pressure was maintained at 90 psi during the dyno run and 85 psi down the drag strip. The 160 pump's "D"-shaped cam profile is the limiting factor as it cuts back fuel delivery from about 3000 RPM on up.

Yes, adding clicks resulted in 2 MPH more overall trap speed however my 1/8th mile MPH was about 1/2 MPH lower. There could be variances between the timing systems at Speedworld = small non-sanctioned track and LVMS = Major NHRA track.

I will say this, the governor springs are tight enough that I'm confident they are not the limiting factor.
 
You're truck's gettin crazy! Seems like just a short while ago you were running mid 12s. You still on head bolts?
 
Yupp 200+k head bolts none the less :eek:

How do you think an HTB4 would run under my 62? Would it be slow to spool?
 
I picked up an ht4b to run under my he351 cw on my wagon swap. But I an running a 215 hp ppump. I am excited to see how it will do now!
 
Congrats on the progress! Love seeing stuff like this!

Care to give us a quick run down of all the current performance parts on the truck/trans?
 
Wow well into the 11's that is great.

Might as well buy a 215 or 180 pump. Sell the old 160, probably only lose $100-200 on the deal. Cams seem pricey.

You have to come down to Irwindale Dragstrip for that... LOL
 
Impressive stuff Will! On the turbo side of the intercooler, I'm running boots that are meant for semi trucks that I picked up at the local truck shop with spring loaded clamps, and the boots have a wire reinforcement around the middle where it is exposed directly to the pressure. I've never blown a boot, although I had a couple slip off before I put some hair spray on them. Haven't had an issue since. Still running stock boots and clamps on the engine side of the intercooler. Might be something you could look into. That's with HE351/S475 pushing about 74psi at the manifold.
 
Will, have you tried running with no tail gate? I've always heard both way. The weight reduction is nice, or that keeping it keeps the air from getting turbulent in the bed. Just wondering if you have done it in 1 of your 1 million passes in the last year, and what you noticed.
