nice looking seats very light, with that length belts would be inclined to cross them

Yeah we discussed that.

BUT:
Crossing is only necessary when you use a HANS device.

And the most important part:
If we cross them, it‘s not street legal anymore. And since our client wants to drive these on the road we can‘t cross it because it wouldn‘t be street legal anymore. 🤷🏻‍♂️
So not an option.
 
the crossing is not just for Hans, the reason for crossing was developed in '70 when top of seat snaps off and belts can start floating around as it still does today

that's shocking take can't cross for street car, have to wonder why any governing body would be concerned with this

Apparently, this ASM Schroth Belts are specifically made to not be crossed. 🤷🏻‍♂️
 
Nice video, some very cool stuff with Verkline. When you come to assemble them, will you weigh each one in comparison to stock? As you did with the engine torque mount in a previous video.

Verkline seems to have also added weight data in parts description at least for larger parts - usually they're little bit lighter than stock.
Really interested in those trailing arms.. as they have adjustability. Also how they compare to OEM trailing arms in terms of stiffness it would be cool to hear.

I have enjoyed watching your videos. What you are doing is interesting from the perspective of what can be done. However I do not think most people want a 500bhp stripped out race car that is pointless on the road and frequently needs rebuilding, Your earlier vids of what I would call road going mods were very interesting from a daily user pov. My point is that what you are doing is relevant to maybe a very few, interesting to the curious but completely useless to the majority who want a slightly better GR. I wish you good luck with your racing project, maybe you can get to 900 kg with a carbon tub and 800 bhp with nitromethane but that is not a road car and lots of people have done that on other cars with unlimited mods. I hope you know this is supposed to be a constructive evaluation of your project vis a vis this forum and not a criticism of your racing and video endeavours.

Oh i absolutely agree with you on most things. 😁

I‘ve done everything i wanted and could that‘s street legal in Switzerland. So there was just nothing left to do. 🤷🏻‍♂️
Of course i could‘ve swapped the exhaust again and the suspension again and the wheels again, but for what?
Or i could‘ve stopped and let the car be as it was.
And the last option was to leave the street legal stuff and go racing.

The thing is:
I‘ve always wanted it to be a Racecar, because Racing is what i do love the most, and now i‘ve got the opportunity to do so with some partners.
And exactly because very few people are willing to do what i do, makes this project very interesting for sponsors. 😉

Thankfully we have every week at least 1-2 GR‘s in our shop for some small or big upgrades, so i can still drive a „stock“ GR every now and then. 😁

But i disagree that it is not relevant what we do, for the majority of GR users.
Because we‘re gonna find weak spots in the car in a matter of weeks and months instead of years.
So whatever parts we break first because we push 500hp or more through the car, will break in years due to old age.

If nobody had gone to 400hp, we‘d never knew that the limit of the OEM Turbo is roughly 400hp.
If nobody had gone to 400hp and raised the limiter, we wouldn‘t know, that the valvetrain is the weakest part of the engine and can cause problems even with 340/350hp.
If nobody had gone over 450hp, we wouldn‘t know that the stock fuel system is at it‘s limit at ~420hp.
If nobody pushed the car to over 500hp, we wouldn‘t know that the headstuds and the headgasket are the next parts to fail.
Thanks to the people who already got there, some manufacturers started developing rods, pistons, camshafts, headgaskets, headstuds etc.
I already benefit from them and their knowledge.

And if Toyota stops producing rods and pistons and camshafts somewhere in a future decade, there will still be manufacturers ready to fill the gap if someone blows his engine of old age and needs a rebuild. 😉

I am one of those owners who benefits extremely from exactly all the experiences Phil has had and will have. I couldn't care less about optical tuning, even performance enhancement is irrelevant to me. I'm only interested in things like the chassis, brakes, tyres, in short, the handling. One or two conversations with Phil have shown me that hardly any optimisation is necessary for the road, suspension adjustment, steel braided brake lines and different tyres are perfectly sufficient. Many other ideas became obsolete, and in the end I saved a lot of money. What I mean to say is that thanks to tuners like Phil, the "normal" user knows better what really makes sense for his personal purpose, knows what to look out for, what the real weak points are. As someone who races, he simply has much more experience than someone who only tunes cars and sells accessories. That alone confirms the fact that he knows exactly how to adjust a chassis, which setting does what. There are many users who tinker and tune their GRs, but very few have a clue. But where should they get this experience from, a loud exhaust, spoiler and a racing seat make no difference, neither make the car faster nor better.

Keep up the good work Phil, it needs people like you. (y)

Low, high pressure or both?

In Aussie YT vid they stated that stock fuelpump would be sufficient for stock turbo. But the (port) injectors need to be replaced before the turbo maxxes out.
guess they ran with e85 so with gasoline it could be different of course.
