turbo task force

[Mains52]

This build is bad A$$ man. I might borrow you patina engine paint idea. Everything looks great.

I did quite a few upgrades over the winter:

holley terminator x
New tilt column/steering wheel with buttons for holley functions
TCI console shifter
bucket seats to accommodate new shifter
roll bar and 5 point harnesses.

Had it dyno tuned and made 750 RWHP at 18 psi on pump gas (90 oct). Then learned my intercooler is a restriction so that's on the upgrade list for this year. I was loosing around 10 PSI through the intercooler. any additional boost over 18 psi didn't pick up power so we left it there plus its just pump gas, guessing the turbo was out of steam at 28 psi and the intercooler was not helping.

I believe my current intercooler only flows around 700 CFM and i need nearly double that to keep up with the 6.0 and s480.

Promptly broke my 12 bolt shortly thereafter, certain i sheared the pinion gear off. So looking to upgrade to a strange S60, new intercooler and a transbrake.

My goal for next year is to run a 9 something and then ship it down to the states to participate in a drag week type event (ideally rocky mountain race week 2.0)

nice!

60s are heavy things, any reason you'd not want to run a 9"

allegedly the strange S60 is slightly heavier than a 9" which doesn't really bother me, probably would help do have a bit more weight back there.

Plus the S60 comes standard with 35 spline axles whereas their standard version of the 9" is 31 spline.

Wow!! You may not pass tech though if you go to an NHRA track. Mounting the fuel pressure regulator on the firewall is a no go, so I'm told.

yeah good catch didn't think of that and it didn't get flagged at the NHRA track here. Should be able to mount on the engine somewhere. I was wanting to replumb the fuel rail feed and returns anyway.

Ended up ordering a quick performance 9", 35 spline axles, disc brakes, aluminum center section with a detroit locker. should be here in January. 5 stars on the pricing and customer service, the guy actaully took the time to chat with me about my parts selection.

Grabbed a set of bosch 2200CC injectors as well, Ive had a persistent hot start issue with my FIC 1200CC injectors since i swapped them in (lots of dead end tuning that never fixed it with both the 411 and holley ECM's) and after talking to an injector shop they said they EV1 aftermarket injectors are notorious for issues. So the new 2200's are a denso style plug. This will also help if i decide to run e85 and give me some more headroom.

Also picked up a garrett intercooler core to help with my current restriction.

Ill post pics when i start working on it, the trucks been sitting on the trailer at my shop since late august, with about a 1' of snow and has been through a couple of -30 cold snaps, maybe that will teach it not break on me again

Ripper little truck. love the color.

Makes me want to put a turbo LS in mine when the time comes for a motor.

[lower50's]

Such a monster but still looks like a farm truck. Love it!!

[akdg87]

it showed up. trucks still buried under snow (since last posting we got hit with three storms within a 10 day period, 50" of snow). right now its -30, and im finishing up a duramax swap on a buddies truck then we will drag it in to start working on it.

[lower50's]

That's pretty!!

Any updates? Really keen to see how you got on with your new intercooler set up.

Thanks,

Joe

i will get some pics of it but it seems to be working fine, i did swap to a S491 turbo from work turbochargers. I dynoed again and it did 840 on 15 psi. (pump gas). Looking at the data log its flowing just fine up to around 16 PSI (1:1) then it starts need a bit more pressure on top of the wastegates to make any more boost.

Right now I'm swapping in a "turbo" cam and the BTR shaft rocker setup. Still had pretty dismal results at the track which i believe is how tight my converter is. I cant build much more than 1-2 psi on the footbrake and its 60' is in the high 1.7's.

This trans has not skipped a beat since 2017 but I'm going to swap to a different converter (higher stall) and throw some nice billet parts in the trans while its out getting refreshed.

1320 video came up for our cash days event and there's a couple clips of the truck in there. Wide variety of cars on a poor traction surface.
