Not that keen on v-banded manifolds,great for swapping turbo etc but the ones i've seen seem a tad laggy.
A gt3076r won't produce anywhere near to 600bhp on pump fuel.550bhp is the realistic max thats with some very good supporting mods.
If your after a 10 second car that you need to run at least a gt35 and imo your need to be running a stroker to make it a fairly decent road car.Some of the mapping/fueling stuff you have listed seems a bit low tech for a 600bhp car.
If you need any help/advice ,no problem.
Just a couple of questions in relation to your post..
Why would having a v-band flange change anything when it comes to spool compared to a 4 bolt flange? Surely its a lot more down to the design of the manifold itself and the flow characteristics? Also, its proven that the Tial V-Band housings flow more than the Garrett equivalents..
What is so low tech about the RS4 injectors and Autotech fuel pump plus a low pressure fueling solution? The most powerful 2.0T FSI cars out there are all running either that exact set up or something that is very very close? Not sure what you would suggest as an alternative?
35r would make good power for sure, but I dont fancy spool up at 5k.. The 3076 should offer great top end but be very drivable at the same time..
The USP GTI with a GT3076r turbo made 620WHP and has ran a 11.01 1/4 with full interior and FWD.. With 4WD and less weight, I think its possible, and ill try my best to make it a reality
No one thought that a mid 12 1/4 would have been achievable on a K04 MK5 until I did it in mine..
