Damn!

That thing really gets out of the hole. 117 trap at that speed is like all wheel drive times. Maybe I'm just getting old.

Old news now. TPG Tuning ran a 10.7sec 1/4 mile with a 128mph trap on stock turbo, downpipe, intake, some high octane and BM3. Some are saying they also sprayed it with a small nitrous shot not sure but this is crazy for the B58!

TPG always pushing the limits, ........ can't wait to get my next ride over to them

When people stop competing for draggy street times and get a proper drag setup on the track, this is what happens. You just can't make those numbers on street tires. But it takes a shop committed to making numbers for this to happen. All it took was the "Supra" name for companies to get serious about it.

Link? They had to be spraying. Those are Stage 2 E85 S55 numbers and I just don't see it on the stock B58 turbo.

They have a different turbo than us
They have better fueling than us
Almost all of the shops are using 100oct race gas + meth and/or e85

Again, not surprising when this is what they have to do to get attention to the Supra owners. They are making race cars, not advertising street tunes.

I know they have a different turbo and fueling, but at the end of the day, you don't pick up almost 20 mph from a tune, dp and fueling mods.

If it's the stock turbo, they sprayed. If they didn't spray, it's not the stock turbo. That's just my take.

I have a hard time buying that when there are so many variables on the table. We don't know boost, timing, turbo size, how much meth they're flowing...anything really. We are already seeing 100-150whp gains on the gen 1 B58 without running race gas or full e85. Why isn't it possible for them?

For me, the big kicker is that they are tuning on race gas yet they don't mention that in any of the posts. People are starting to notice and ask when they can provide numbers on 93oct. But 100oct PLUS meth or 100/e85 PLUS meth is a huge advantage over our OTS tunes. Just wait until they're tuning on full e85.

I fully agree with you and noticed too that the dyno runs said 100 octane/e85, but didn't see meth. I'm curious to see Stg 2 93 and E30 OTS numbers. Full E85 would be nuts!

I know the TU motors have the fuel system advantage, but I thought the turbo was different because it's integrated into the manifold. Are the turbine and compressor different as well? I thought that wasn't the case.

Pretty much all turbos since the N54 days are integrated with the manifold. It's a one piece unit. The difference with the Supra engine is that 90% of the manifold is integrated into the head of the engine. It has 2 outlets so there are short runners to the twinscroll turbo.



On our gen1 B58, we have a full tubular manifold separate from the head. But it's still 1 piece with the turbo.

Pretty sure they sprayed and are deleting comments about nitrous on their social media posts.

The more I think about it, the more I have to agree with you. 128mph trap speed just seems impossible without some sort of significant power adder. I know the turbos between the B58 and B58TU are different but I would need to see both turbos disassembled in order to compare the compressors/turbines and see if that would result in a 4mph trap speed increase. No issues with the 124mph trap speed since we have seen other B58 powered cars putting those numbers down (at least on Dragy).

I think the only way to prove this would be if TPG can get the same results on other Supras running the same setup.

That's what I was getting at. They do seem to get out of the hole pretty well, but power dictates trap speed, and seeing as that they trap 109-110 stock, 128 just isn't plausible without spray. Full e85/tune/DP S55 cars can't pick up anywhere close to 18-19 mph on stock turbos, so I just don't see a B58 car doing it, regardless of iteration.
