You need 3 bar over pressure which that standard turbo doesnt deliver , and if it did ,i doubt the engine block would like it multiplied with diesel compression and much more heat and extra power stroke pressure.
That leaves skimping on air fuel ratio with overfueling and no air(turbo pressure) riding with massive smoke when that power is generated.
and offcourse your tuner promises some figures if you pay and dont complain if it blows up or wears out .

Ever been on a dragstrip? insane power with insane boost figures with mehanol. those engines blow up regularly or wear extremely if they dont blow up right away.


That power figure has a price beyond that pink cloud
i mean black clouds, fluffed with some tingling bearing sounds

yes it is dyno tested on an eddy current braked dyno

it would need a hybrid turbo, why does everyone go straight for boost? doesn't necessarily need to have a stupid high boost. i was only on 26 psi with what I got.

its all about egt's and soi and a bit of afr you watch the egt's if its going too high its too much

you dont need massive smoke to gain power if you get the SOI right massive smoke is for amateur tuning just dump in fuel to get power anyone can do that and its not the right way to do it.

any tuner who promises certain figures isnt worth using. its always estimated and dependant on the health of the vehicle.

drag strip cars are different they're tuned for the drag strip specific parameters that are used to optimize them for 1/4 mile runs completely different to something you would use on the road you're not just doing 1/4 miles all the time ffs!


do you even know what fuel pump this has and do you know what injectors are capable of? do you know whats inside the block? have you ever had one of these cars on the dyno on a long session?

i know all of it because the tuner has told me and based on that and other factors says the figures i mentioned are certainly achievable.
