question : K26/GT3071 Dual BB Turbocharger

[A80Avant]

252 actually....
nice cooked up number for you!

[EspenW]

something is off. can you post the graph?

[A80Avant]

i havent got it yet.im waiting for them to email it to me.i will post it as soon as i get it.

as i wrote on my project thread,it seems that the person handling the dyno altered some kind of drum resistance from what i can think and barely managed to see as he quickly changed through the settings so im guessing this is why it produced too much torgue (560Nm) and 360Bhp crank when the car has 1.9bar overboost and then 1.7bar steady boost.It is way off.

Maybe he let off long before the rev limiter.

[K7ERG]

Was there wheel spinning as this throws the rollers out.

034 motorsport chip set

Suitable for all AAN, ADU and ABY code coil-on-plug I5 20v turbos, requires 3.0 BAR Map sensor and 440cc injectors, included in the kit. Requires a 4.0 BAR fuel pressure regulator (stock on the AAN, available for the ADU/ABY) and stock MAF in all applications. For advertised results, we also recommend the RS2 exhaust manifold and 3" DP and free flowing exhaust.

We recommend this tune for all motors with stock internals, upgraded engine rods or pistons not required.

Brand new code, we did not start with a previous chiptune, all mapping is original from 034.

Specifications:

-23psi overboost, 20psi to redline, 7200rpm rev limiter

-Air/Fuel ratio 11.5-11.8 under boost, 14.7 under light load and idle conditions. Recommended for 91-93 octane fuel.

-325 wheel HP (to the wheels), estimated 400-425 crank HP.

-Injector duty cycle 85-90% max. under full load at peak rpm of 7200rpm.


Chip Tuning Package includes:

- Quantity 5 flow matched 440cc Bosch injectors

- 3.0 BAR VMAP sensor with installation accesories

- 034EFI GT3071R Stage I Chipset (fuel/timing and boost)

- 034EFI 1.9 BAR wastegate spring

Map Select Option:

- For an additional fee, we can supply a map select feature with the chipset to allow switching between 2 different maps. Currently, the option we offer is a + 3psi map for a 26psi overboost holding 23psi to redline for 350 wheel HP or an estimated 440 crank HP. We recommend running 93 octane fuel minimum with this chipset or preferably 100 octane for optimal performance.

[A80Avant]

there must have been some wheel spin which is why he asked for a second person to sit int the car,but he dynoed the car after he went in

[K7ERG]

what make of Rollers did you use?

Strapping the car is also a way of getting false readings

[A80Avant]

it was a maha LPS 3000 dyno.

At what rpm did you make 560nm?

[A80Avant]

i think it was around 3800rpm,maybe less because spooling on 5th gear comes around 3600-3800rpm.
i still havent got the email yet.grrr

[4WheelDrifter]

That's what I said more aggressive mapping

Remember Ross was at 2.0 - 2.1 bar which is on the edge of the garrett map.

I was trying to back you up with a real world example.

Sorry bud, so use to the snipers
