TCI Engineering's Turbo C10
 
This project was started back in 2013 but stalled while we built our 2nd Gen Camaro. Now that the 2nd Gen is complete and getting beat on it was time to get back onto the C10. The only problem now was R&D had other product related projects going so they had little to no time to devote to the project. Not wanting to let the project sit any longer I worked out a deal with Ed & Sal. They would make me project manager and give me plenty latitude to build it as I seem fit. A decision they will soon regret. :drive:

We are still trying to decide on a name for the project.

We've made a few more revisions but the project is coming along quickly.

There was some discussion about which c-notch design we were going to use. The round style won out almost unanimously.

Things to note: Driver side spindle is different than Passenger. The passenger side design is our new custom set-up. It is based on a C10 pin and uses the factory lower ball joint with a heavy duty Moog upper. The steering arm is removable and helped us attain the geometry and turning radius we desired.

Here are some of the pics from the Shockwave mock up yesterday (based on a 26" tall tire). This is with the 2" Ridetech shock extension, I am hopeful the 1" top will clear the control arm cross shaft. This will give another 1.125"-1.25" of compressed travel but will keep the suspension below its designed operating range. I will mock these up today sometime just to know.

Our bumper is bent up on the driver side so the frontal view looks a little off. The driver side is roughly an inch higher than the passenger.

Looking underneath the bumper at the crossmember.

http://i981.photobucket.com/albums/a...ps1a7aa826.jpg

This picture is a little deceiving because I couldn't get the camera low enough to get the true height. The crossmember is closer to 1.75".

http://i981.photobucket.com/albums/a...ps6a592b45.jpg

The front frame head just behind the front bumper. Keep in mind that the rear suspension is still at ride height so once it is aired down this height will actually go up.

This is the front cab mount. Keep in mind that the rear suspension is still at ride height so once it is aired down this height will go down.

May 2017 - When I took over the project

So anyways, with some freedom to proceed how I choose I began to mock up some things. First and foremost I put some shock simulators in place to mimick full compression of the 5.2" travel ridetech coilovers. Then I placed some wheel simulators in place mimicking 26" tall tires. I know this is probably less than what some may run but I plan to run 18x12 wheels all the way around with a 315/30/18 Falken tire which is 25.5".

Here is a pic with the frame at full compression.

http://i981.photobucket.com/albums/a...ps24chuplm.jpg

The frame under the front cab mount is 5" off the ground.
http://i981.photobucket.com/albums/a...psg3hqwxqz.jpg

Something that has been lingering in the back of my head is the original upper shock mounts we made for the front end. The engineers ditched this design early on because the truck sat too low. Basically the inner fender had to be raised with them so they felt our kit wouldn't go this route. Anyways, we still have a couple of the original design mounts sitting in a box. There is roughly 2.5" difference in height between these.

http://i981.photobucket.com/albums/a...psvz07e18z.jpg

http://i981.photobucket.com/albums/a...pskzzjqd4a.jpg

The rear axle sits above the frame but it does clear the bed.

http://i981.photobucket.com/albums/a...psfe8spdxt.jpg


So, I will try to keep this thread updated a little more often. It will be slow though since it will only be an hour or so at a time.


June 2017

With the power this thing is going to make, we're going to need a strong foundation. I'll work on the back half next week.

http://i981.photobucket.com/albums/a...psfvbrkxta.jpg

July 2017

Worked on the rear boxing plates. I removed the standard bolt-on frame plate that comes with the Torque Arm kit and placed it on top of the rail. I don't need to step the rails that far to get the desired ride height but it was a good starting point.

The frame is countoured in this area so I will have to put two bends in the new boxing plate to match the frame. R&D is really busy right now so I might not wait for them to draw these up and cut them on the plasma table. I might just trace and cut them out with the hand held plasma. Sure it's dirty but I am trying to get this thing back to a roller by the Brothers Truck Show.

We placed a rather large order with Holley and parts are starting to show up.

These 83 lb/hr injectors will likely be too small for what I've got planned. But it'll get us started on pump gas.

http://i981.photobucket.com/albums/a...psjtg7e68g.jpg

I've got some ideas for a coil mount that involves the valley cover. The intake manifold hasn't arrived yet so that'll have to wait.

There's definitely going to be some late nights and weekends in my future.

Messing around with coil mounts options today. The intake manifold is still in transit so this could all be futile.

http://i981.photobucket.com/albums/a...psu9mei4z2.jpg

http://i981.photobucket.com/albums/a...ps8yxr4srd.jpg

The Holley Hi-Ram is in our possession now so we can actually do some mock up with the coils. There is plenty room to mount them underneath it. We just want to make sure that they are serviceable somewhat easily. Probably make a one piece removable shaft so they come out as a unit.

http://i981.photobucket.com/albums/a...pstyz3ctgi.jpg

Some more major components have arrived. We haven't done a bagged shop project in a few years so this is kinda exciting. Ridetech triple adjustable shockwaves 5" travel front and 6" travel rear. Dual 3 gallon tanks, dual pumps and their pressure based ride control system.

http://i981.photobucket.com/albums/a...psp1xloxoc.jpg

TCI Engineering 09-22-2017 09:08 AM

So the thing about boost. It's just a measurement of restriction. Less restriction, more flow at a given pressure. On a naturally aspirated LQ4 these 230cc AFR heads would be overkill. I've already said too much. Those that know me, know the direction this is headed.

http://i981.photobucket.com/albums/a...psac6wfg3z.jpg

We finally got the frame rails back from sandblasting. Well......they only baked it apparently. Anyways, waited this long so we are moving on.

One of the guys in the shop mentioned that we had a chassis dolly in storage. He thought it was sturdy enough to build a temporary fixture out of so we took a few guys down there and grabbed it. Sure enough, this thing is a monster and honestly I am kinda glad that it is short. This way I can place the cab and bed on it if need be. Will come in handy with doing a body drop. ;)


I had to install a CPP driveshaft loop because the stock one would interfere with the chassis dolly.

August 2017

I am finally back in town so it's time to make some real progress. I spent my lunch today tracing and cutting one of the rear boxing plates. It's sucks that I had to cut it with the hand held plasma vs. the hi-def but I can't wait for R&D to draw the plate(they're super busy finishing up the squarebody 4-Link).

So basically what we have done is give the rear suspension an extra 3.5" of travel. The bottomed out height before is where the new set up will be at ride height. I left the rail height at 6" at the step so there is plenty of strength for towing.

Making progress on the stepped rails. Just a lot of mocking up, grinding, cutting. welding and not necessarily in that order.

Dimensionally I am pretty happy with the outcome. Side to side height is perfect and front to back placement are within 1/32". I am off .25 degree of vertical on the driver side(should have cross braced it before the heat). I've still got work to do on it cosmetically though.

http://i981.photobucket.com/albums/a...psli3sxzlm.jpg

Braced the top of the step and cut the stock frame piece out.

http://i981.photobucket.com/albums/a...pshcxn1eqn.jpg

Got some cool(errr hot) parts ordered this week. :mm: No picture tease yet but parts are on the way. Getting real close to engine/tranny mock up.

The frame is absolutely ugly right now but the fitment is pretty darn good. Had to section the top and bottom(note the cut) in order to pull the outer wall of the frame into the step. Still have to clean it up before laying down a bead.

http://i981.photobucket.com/albums/a...ps6fjtbgrk.jpg

I wanted to add a little extra bracing inside the frame rail where the front shock mounts. Main reason is our engine mounts triangulate the frame and the crossmember but I am setting the engine back. It's just a piece of 1x2.120w tubing

http://i981.photobucket.com/albums/a...ps22wrtvfz.jpg

Started working on the front boxing plates. I cut the driver side with the handheld plasma like I did the rears. Once it fit I used that as the tamplate for the passenger side. There will be a filler plate added to the top of the rail to close the gap.

I have always hated the 67-72 dash. It's flat, tall, ugly and boring.

So about 5:30 last night I'm in the shop and Ed(Owner of TCI) comes walking out of his office. I'm sitting on a short stool inside the cab just staring at the dash contemplating things. Ed says "You know, when I was building my Mustang I wish I would have cut the dash out. It would have made my life much easier". That was all I needed to hear. I grabbed a sharpie and started marking it up. Removed the few retaining bolts and fired up the plasma cutter. I left a one inch flange to attach the replacement dash to later.

With the dash out it became very clear to me how the tunnel and firewall should be cut. I knew I wanted to push the engine back, I just didn't know how much.

So I took some measurements and rigged up a floor mounted fixture to use as a guide with the plasma cutter and went to town.

Once you exceed 3-4" of setback things start to get interesting (difficult). However, once you go beyond 3-4" it's not much different to go 10-12" vs. 6". In the position below the engine is back 10" from the factory location.

Wow! Might as well go mid-engine at this point, lol. Seriously, I dig the direction you're taking this.

Chad Ryker had a bad(good) idea on Instagram to make it awd.

Ditto! That is mid-engine as it sits--note the front axle centerline in relation to the heads. This truck is getting very cool.

Apologies for the ignorance. I know it's good to have the engine pushed back a ways rather than hanging way out in front of the vehicle, but is there extra benefit to having half of it inside the cab?

Excited to see the work on this truck!

You'd be surprised how little moving the engine back 3-4" effects weight distribution. At least with a lightweight LS based engine and a long wheelbase vehicle such as this. Moving a battery from the front to the back can have more an effect.


We have a few different sets of headers sitting around the shop we use for mock up. Of all the ones I tried our own off the shelf headers fit the best. Mainly because the rear cylinder primaries go forward slightly before going down. This actually allowed me to move the engine back another 2.5"(12.5" total) with relative ease. I had to raise the engine in order to keep the pans(engine & tranny) above the bottom of the frame anyway. It had to go up over an inch(too much) in order to keep the transmission tabs off the tunnel. Now I've got clearance issues with the intake manifold. Next week I'll trim the tunnel a little more where the tranny tabs are interfering so I can bring the engine down roughly 1/2". This may or may not be enough to clear the intake manifold again.

Needless to say if the engine stays this far back I will have a constant foot warmer.

Nice fab work, and great project.

You're right! I didn't even think about it that way. I was thinking have the engine behind the cab.

Haven't made much progress lately. Ed and I have been discussing the chassis center section and engine placement at length. There is no physical way to lower the engine in place so we've decided to build a removable lower section of the chassis. It will have 6 attachment points and allow the body/chassis to be lowered over the top of it. I've built this over and over in my head so many times that I get disappointed when I walk into R&D and see that it isn't physically built yet. I should start on it today though.

Much like the engine placement, cab placement is still up in the air. I had read and spoke to a few C10 builders that if you body drop .75" the bottom of the pinch weld will be dead even with the bottom of the frame. That's not the case on this truck. I am currently using our Camaro 3/8" spacers(which are roughly.75" less than the stock rubber mounts) between the cab and frame mounts and the pinch weld is still well below the bottom of the frame. On top of that the rear of the cab is lower than the front, using the frame as reference. This kind of works to my advantage though. I had kinda wanted to tilt/rake the whole body down a degree or two in the front. My plan is to make the bottom of the cab parallel to the bottom of the frame.

All of that means that the core support bushings will also need to be modified to assume the new angle. This pic is with roughly 1" less thickness.

I was at a stand still with cab placement because I wanted the pinch weld rolled up flat. I'm an OCD photog so i've seen way to many good looking trucks be ruined by the pinch weld.

Ed was working on shock placement while Sal and I were at SEMA. Here is what he came up with. This is basically our original upper shock mount raised another 7/16". She's going to be loooooooooooooooooooowwwwww.

SEMA, Pleasanton & Scottsdale, 3 weekends in a row working out of town has slowed progress on the C10.

We needed a little room under the cab for intercooler piping.

http://i981.photobucket.com/albums/a...pssae01wha.jpg

Still need to roll the edge to add some strength.

http://i981.photobucket.com/albums/a...psdnkxbhmz.jpg

Started working on the chromoly center section. Form fitted around the tranny on the bottom side. The two middle tubes aren't mounted yet. There will be a couple cross braces added for the tranny mount & driveshaft loop.

*NOTE* The relationship between the front of the bell housing and the cab mount. ;)

The Torque Arm will end up filling out this space so I needed to devise a way to gain clearance. It took some thought to get the angles right but the bend came out perfect (Even though chromoly deflects so much after being bent).

Still plugging away on the center section. Built the main tranny hoop and tied it in with some downbars. It is just tacked in place at this time. I still need to throw the cab back on to confirm placement. It'll make sense why the tubes are on top of the frame once the cab is back on.

https://i.hmjimg.com/images/2017/12/...0756221.md.jpg

I still need to make a couple tabs to close out the round tube on top of the frame.

https://i.hmjimg.com/images/2017/12/...0936411.md.jpg

The rear tube placement must be 21" behind the front one to fit properly. I plan to tie the driveshaft loop, tranny mount and Torque Arm mount all together in that area.

We had our friends at California Rebuilt Exchange build us a quick ratio manual rack. Yes, that's right, a manual rack with what will likely be 315 or 335 tires on the steering axle. I better start eating all the spinach. :lol:

In all seriousness though. We are going to begin testing the feasability of running EPAS with our suspension. I figure that if it can handle this type of load & abuse then pretty much every other application will be just fine.

Which epas system are you going to test? There are a few popular ones in the market place...

Jimbo1367 12-08-2017 07:38 AM

Are you going to gusset the UCA mounts? Please say "Yes"

Ummmmm........junkyard...... lol

We will likely try both the Vue/Equinox and the Prius boxes. The Vue/Equinox appears to be more robust but has some "On Center" concerns. The Prius might be the easiest to adapt but just not sure of longevity under this much load.

Yes, I will add gussets. That whole area will be tied into firewall down bars as well.
