Turbo BS Thread

Haha um I think you are still in overkill mode.

 

Your truck is going to be more akin to a shifter kart with those!

This could help that shifter kart response too.

 

Ummm sir-are those flanges for a 2TR?!?!

 

In the 304, they are. 2TR turbo header flanges. For hopefully a mock-up to come soon enough.

 

Flexing the goods. Those are mighty fine looking

 

From the same professional that made my 321 Stainless 1GR flanges.

Now to start collecting materials to bring it to life.

 

Planning for top mount? I'd kill to have a decent quality manifold! This Chineseium steel is killing me lol.

 

That I am

 

I am all about those! I'm still on the fence about the TD05 or the Holset... it really comes down to how much I'm going to use it as an autocross truck, or how much I'm going to use it as a street truck.

 

Let's see what happens with @BassAckwards and how responsive his is. It should be very responsive. With room for growth.

So then it just depends on how much power you want. For autocross, you'll need tap throttle response. Which would be more like OEM performance.

 

Not quite to the whole putting turbos on part, or the putting the engine in the truck part either... But here's the bottom end of my 454 (now 460) for my C10 drag truck project.

 

Oooooh that's smexy!

 

I need to compare compressor maps... twinscroll holset vs regular td05 16G "big" turbo is like comparing apples to oranges I think.

 

Completed the valve to piston clearance, already, yeah? I am assuming that is what those blue marks mean.
Otherwise, that is going to be a monster!

 

Oh yeah, I did a quick mockup using a hand crank to open the valve since I didn't wanna size out pushrods yet. Plenty of room even with the generous dome. Should be 9.32:1 compression ratio, so still boostable. Just finished porting a set of heads for it and I've got to finish cleaning them to put em back on.

Tracks might be in your future. Skip to 2 minutes for the track

 

I need more track time in my life.

 

It looks like a ton of fun with a boosted taco.
Think that hilux is up to around 700 hp now

 

New shiny came in the mail.

 

Hey guys,

So OVT/Mat's recommendation to me was that since the upgraded fuel pumps and controllers probably won't be available til next summer at least, to use my boost controller to drop my max down from 9-10 to base pressure for the kit, which is 7-8, because I want to be able to tow my little camping trailer up in the mountains without having to worry about running out of fueling and misfiring. It's only going to weigh like 2k lbs fully loaded but idk if I'll be potentially spending multiple minutes in boost in some of the higher altitude areas, even if it's only like 3psi.

So anyway, yesterday I turned down my boost controller by 15 clicks, which is just over 2 full turns. Got about a 1psi reduction out of it from what I observed when driving. For the most part, I seemed to max at about 8.5psi, once in 5th I did hit about 9. Whatever.

This morning I turned it down by another 14 or 15 clicks and stopped getting the click feedback, just feeling tightness/resistance. Continued another estimated 2-3 "clicks" for a total 17-18. Obviously I'm reaching the end of the boost controller knob's available travel.

What I wanted to ask was if it anyone knows if you can tighten it too much, if there's such a thing.

If I can get it to max around 8psi with how it's set currently, I'll be happy with that I suppose. All I want to do is comfortably be able to sit in boost for an extended period of time without having to worry about perhaps overtaxing the stock fuel system.
