Hellion Twin Turbo Mach 1

[Weeee]

Folks,

I wanted to draw your attention to a local fellow building a twin-turbo Mach 1. I had the opportunity to chat with him at a racing event; he has a clear vision for the car and the mechanical knowledge to get it done. I don't believe he is on the forums, perhaps we can change that together?

I'm following TruckandRoll since he got the Mach 1, really nice guy, great videos. Will be nice to follow his quest and results.

Just wanted to say thank you both for the kind words. I honestly should have had a better presence on the forums before but Tom posting this will be a great catalyst. I'll be doing my last bit of racing this weekend with my wife while the Mach 1 is naturally aspirated and hopefully diving into the twin turbo installation starting on Sunday. I'll keep this post updated with pictures as I make progress.

Welcome to the forum, I have enjoyed watching you and your wife race, along with the modifications you have done on your Mach. Really looking forward to the turbo set-up as well.

Quick update: This weekend I started to install the kit. So far I got the driver side Hellion 4 into 1 header installed, oil feed installed, and passenger side header in place but not tightened. I definitely learned a few things. First the instructions are lagging a bit. Looks like the oil feed connection has been updated. This requires you to re route the oil pressure sensor wiring a bit. Second header bolt access is a PIA. I wound up having to pull 4 manifold studs on the passenger side to get the factory manifold out. I pulled the starter too for more access. Here are some pictures comparing the stock pass side manifold to the Hellion 4-1. Note the larger collector diameter and smoother transitions vs the stock style.

you might have to grind down on the o2 sensor block off on the pass side I had to on my gt350 using the 4 in one headers also I took all the studs out and went with the stage 8 locking bolts made install way easier

Thats good to know. I just got them mocked up on that side with a couple of studs in and a nut partway tight to keep the header from falling. Ill have to take a look and see. When you did yours was the oil feed somewhat janky? Mine is multiple pieces together (i.e., adapter for onring fitting, SS hose, tee, another adapter, etc. I undid the oil pressure sensor wiring and re reouted it on the other side of the alternator.

And here I am wanting to know more about the white Comet and not really caring about the TT install....

did not have to reroute conector don't know if there is a difference between the 350 and mach 1 sensors or harness

Its a 64 with a 302 out of an 80s pickup. Its been a super reliable fun driver. I swapped the carb and the AOD for a T5 and its really fun to drive. Eventually I want to redo the heads, roller cam, etc. but parts are currently scarce and somewhat expensive. It was almost the project I went with before deciding to go TT on the Mach 1. I have some videos and a dyno on my YT channel

So maybe they changed the sensor style for the Mach 1 (or its a model year thing). I also noticed when removing the starter mine appears to have 3 bolts vs. 2 so apparently some minor changes. Heres what mine looks like (I prefer your setup)

all starters are 3 bolt but yeah not a big fan of how they set that adapter up but it looks like the mach 1 has metric orb threads where the gt350 Is a pipe thread for the ops

Dang you move quick. I look forward to watching you take down the Lambo's at the next roll racing event.

It's funny you mention that. I was out racing last weekend. In stock form the Mach 1 is way underpowered for those events. I lined up next to an Underground Racing Lambo. He had twin turbos and a sequential air shifter. I told him I planned to cheat and jumped the start line early, he toyed with me for a second, and finally toasted me. I'm not sure the turbos will put much of a dent in the Gaptism I received but it will certainly help

You building this for drag racing or track ? Personally I'd do the track route.
