BUILD My MKIV Supra build-ish thread...big boy 3.4L motor time

[Pressure Ratio]

1100whp/850wtq at 35psi

Injectors are still hanging in there?

Plenty of headroom with the ID2600's. We're going to push to 40psi unless the car diminishes on returns

superb. How often do you anticipate driving on kill mode? i have a 700hp car and its hard to go wot cause it feels so fast

Honestly probably very little on full kill mode. Even on the old setup I was on 550whp for 99% of the time I drove the car. I'd only push it up to full 700whp when I was doing a pull and that was very infrequent. I'd rather have the car live than beat the piss out of it and make it destroy itself.

I get that part, but with that said. Why did you decide to build it for XXXXwhp if your only going to use it 1% of the time?
I'm not knocking you bro in the least bit, its your hard earned money and spend it as you please. Also I'm really enjoying this build, but I'm just curious why. Does it increase the re-sale value, or is it just to say I have XXXXwhp, FAFO chump lol.

Every build of mine (I know not even close to apples to apples) that had a power adder and or built motor. I'm using that power every chance I get and I will push it to the limits within reason.

This is why my shit breaks i roll around on nothing less than 1k lol

I drive my car all the time. If it was a weekend only kind of thing then I would have a different take on it. I literally drove it from Chicago to Houston in a day so this car will be driven no differently.

I was the opposite with my TA. Part of the reason why that setup worked so well was I would only roll around on 12psi and wouldn't flog it repeatedly. Just a rip now and then but enough time between pulls to let it cool down. I had that motor for a good 4-5 years before I had it refreshed and even then the machine shop said it looked great. When I was at the track though I had no fear of breaking and would push it as hard as I could. I was so confident with the car that in the final years of owning it I would just drive it to the track. Run a low 9 with a 1.2 60' and then drive it back home.

Yeah, that's a good thing. i unfortunately did not have any type of boost control with the blower so it's all on all the time lol. I Do the same kind of shit make a rip and chill, sometimes a hard highway pull if needed lol. Def nice to drive to the track and rip a 9 and drive home. I doubt I would ever drive to the track, not that I couldn't but just the "piece of mind" knowing I have a trailer to get my pile home. Car is def bad ass I wanna see some 1300hp pulls

Oh for sure, I liked having access to a trailer just to ease my mind if I’m concerned about breaking. I’ve towed other people home and drove my car back a few times

 

[IDAFC21]

god DAMN!

Same, full tilt all the time on everything I’ve ever built lol, fortunately most of them held up ok

 

[SleeperLS]

That sounds nasty

Being able to run less power is very helpful in an RWD car that makes 1200+hp and 1000+ft/lbs of torque at the tire. Especially on dusty or cold roads where ridiculous power is just going to make things worse. If not unsafe. As well as not being harder on parts in the motor.

But with a turbo car and the newer stand-alone ECUs out, you can run a moderate power tune, change boost settings on the fly, or run a scramble button should you want the option to jump up the power instantly. Some of them even allow you to change the tune on the fly. As far as flexibility goes, a turbo car with a standalone ECU to control boost and maps, you can't get any better.

on the street, the Carpri with the big power tune could haze the drag radials at 40, 60, or 80 mph. Especially in fall with the streets cooling off. It didn't make 1000 ft/lbs of torque either. But it was no quicker than the car was with a 1/3rd less power as it would hook on that lower power. And had less potential for scary moments haha

I have a BTI gauge and it is canbus enabled so with the motec m150 I can control the boost and traction among other things from the gauge directly. No need for additional switches and such.

That should be about the limit of that turbo I think, but it is such a great road friendly turbo with the way it spools and the power it makes, enjoy! Car is awesome!!

Yeah for sure, I was hesitant on going with an pt8685 or similar size as it would make the power but be a dog for 95% of the time I’d drive it. This is a good cross between making good power but a responsive ripper on the street

 

[IDAFC21]

So awesome

Tell us more on the sound aspect. I'd love to get more details. What all was changed that affected the sound and so you like it for the better or worse. Congratulations!

EXCELLENT. However, tell film car to just have the window cracked like 1-2", and the sound quality will be WAYYYY better.
