Temporary Power Plant

With my motor being down and having a tremendous amount of things going on, I wont be getting the pleasure of running my truck for a while.

However, my buddy has a 56 Chevy truck that was a single turbo LS and it is in need of a cage and rear chassis work. We have come together and are putting his now twin 69mm turbo power plant in my truck. He will be leaving his 56 with me to have a local chassis shop back half and cage it, similar to my set up.

We had to redo a few things in my chassis like cut the motor plate free and lower it so the back of the intake would clear the fire wall. Had to move the alternator bracket which was on the frame. Some minor stuff that just eats time.

But we should have it up and running for a dyno session on Thursday, then to the track on Saturday so he can make license passes.

He has a couple sponsorships and my truck will be at the Vegas LS fest in one of his sponsors booths and running the new truck class.

It will be interesting to say the least.

Re: Temporary Power Plant

I've been following the feud on Instagram (not sure if it is real or not). Can you give us some specs on that motor?

Re: Temporary Power Plant

Tiny,

It's not general knowledge yet that we are doing this together. My guess is there will be more announced by my buddy in the near future.

It is his 370" LS shortblock wearing my heads that flow 365cfm and by my standard a small cam. Turbos are 69mm with truck manifolds. It should make decent power.

Re: Temporary Power Plant

Made it on the dyno.

We hadnt even fired it due to a fuel line leak. We had to make a couple new lines and the steel braided i had laying around puked fuel badly. The local fitting/line supplier met me at the dyno and we fixed that.

Then we fought a map wiring issue. We had to wire in a 3bar map and the diagram I had was confusing. Connector had letters while diagram had numbers. We sorted this out.


Fought boost controller / waste gate springs. 8lb spring first pull it went to 280kpa (27ish lbs) real fast and we lifted. Turned the controller off, same thing. Moved some vacuum lines around and it got better but we still saw 15lbs with no controller riding the springs.

Then we fought fuel. For some reason my Weldon 2035 was not keeping up. Found it was only seeing 9 volts.... jumped it direct to a battery but still loosing pressure. Thinking it needs a better alternator and perhaps a boost a pump.

It made 78X Rwhp at 6,100 going lean. It should spin 7,200 all day long. So there is still a lot of power to be had.

Re: Temporary Power Plant

Holy crap. 780 Rwhp and an easy 1000+RPM to go,, that's making some nice steam.

Keep us up to date once you get the problems sorted out.

Re: Temporary Power Plant

What is interesting is getting it from 9v to 12v on the fuel pump, no changes to the tune, it picked up 70ish rwhp. That was at 6100 rpm and 14afr.. should be 11.3 to 11.7... I figure fuel alone will make more power.

Re: Temporary Power Plant

Fuel pump got rewired directly to the battery through a fuse and relay.
Alternator got swapped to a higher amp variant.
Truck got on the dyno (not sure why limiter was not bumped up, I was not there) but it made good numbers at 15lbs and only 6,500rpm. I am not at liberty to say what it made but it will likely run as fast or faster than I have gone.


Truck went to Irwindale and on 8lbs ran:
1.67 rolling in to throttle (data logger shows it wasn't even fully on the verter until 1.3 seconds in to the pass)
4.3x at the 330"
6.6x at 85mph (lifted at 5.1 seconds in the data logger)


For reference I looked at one of my 9.4x passes:
1.41 60'
3.96 at the 330'
5.9x @ 116mph


I would have to say, most of the difference is in the 60' and this combo makes boost on the 2-step/tbrake. So I don't think that will be an issue I honestly think at 8-9lbs it will comfortably go 9.4x. My buddy Griffin will be running it at LSFest in the new truck class.

Re: Temporary Power Plant

8lbs of boost with 2step set at 4,000rpm (2lbs at the line). This in Vegas so elevation and hot. Should be interesting at 15lbs, sea-level and 70* temps..

Re: Temporary Power Plant

Looks like you are getting a handle on it. What happened on the RT on that pass?

Re: Temporary Power Plant

RT was simply a function of it being test and tune session, Griffin getting used to the program in the truck and making his license passes.
