I just did a 570+ car on stock clutch and so far it is holding fine for the time being. Torque is around 450. Trick is to not lug the engine and create a high load low rpm situation when the torque hits. That initial stress is brutal. But eventually the stock clutch will fail.
Had a customer with a similar issue. We ended up doing a direct wire kit towards the pump, with new cannister and fuel pump and that solved the issue. Check the electrical feed to the pump.
On the ethanol front I would suggest running a e20 mix max to not tax the pump at the track. On the street I feel you can get away with e30 with a slightly leaner afr.
I would step up to 5w-30. That is what I run and 0 issues. I’m not a fan of the 0w-20 think it is too thin for track duty once some heat gets in there.
Hondata is the one currently doing jailbreak tours. Right now I can do shipping ecu or if there is enough interest in the area, 10 plus cars then it can be scheduled.
This is fbo, fuel system and canflex and the kuro+. Car had easily another 40-50whp available, just left it there since the customer did not want to push a stock engine too far.
So you can see gains without a tune doing some bolt ons. But to take advantage of that a tune will yield dividend better than just bolting them on. The car has some room on the factory limits to get some partial benefit from better parts.
The FK8 turbo is slightly larger than the FL5 turbo.
The FL5 is a more efficient turbo in the sense of that it makes almost just as much while being smaller but up too it does drop a bit more compared to the FK8 one.
The FK8 had more fuel so was able to run a bit more ethanol but after a...
