Finally i did it ,3B to RS2 setup dyno results

[Rocco]

as tittle says...

i am glad to see that the last dyno i tried worked well ,because i had 2 bad experiences before in one month.

the first one was 307cv with 455nm¡¡

and the second one 334cv with 502nm¡¡


and now the last.... with 2 different ECu septups with of course 300kpa map sensor in each ecu.

in a cold day i could have the 400cv¡'¡ and with the RS2 IC...in the future better¡¡ because i am runing with the small 3B original IC

wich of both ecu setups do you like more?? the first with 391cv and 644nm? or the 375cv with 627nm with better topend power?

[[RPM]]

is it normal on a rs2 setup to loose so much power in the high rpm?
is it due to the turbo loosing efficiency?
best of luck

[newsh]

Yeah its falling off realy quickly after 4.5k



Here's my Coupe 3B , mapped by Mihnea March 2005. RS2 Turbo, IC, manifolds and injectors,
Bosch Motorsport Fuel Pump, 7A FPR. Samcos.

331BHP and 359ft/lb .. missing /holding back between 4 - 5k. (Can't remember how I fixed the misfire..)

Not a brilliant graph but you can see there's a good spread between peak torque at 3k5 and peak power at 5k5.

[newsh]

Are you still on stock rods?

[T2Andy]

Is this a RS2 turbo or hybrid ,that's lots of torque

[Rocco]

it is a complete original RS2 turbo,complete new

but with 2.0bar in 4th gear and after 5000rpm loosing bost quickly to 1.5bar ,holding it to 6500rpm

maybe with the RS2 intercooler i could hold more power and torque??

[Rocco]

Are you still on stock rods?

yes my friend, the engine´s internals are complete stock

but of course my clutch it is upgraded : spec stage 3+ for 450hp and 700nm

and i am using a gearbox from the coupe quattro 170hp with the ARv gearbox driveshafts

[T2Andy]

It maybe running rich after 5000k which looses you power like mine does but good torque

[Rocco]

It maybe running rich after 5000k which looses you power like mine does but good torque

i think that not,as the they said me. they did a Lambda dyno test too for see the values and they said me that everything it is Ok

and later in my Wideband gauge with full boost in 5th gear 2.1bar i see 11.2/ 11.3 AFR

[Rocco]

with a custom ecu setup it is possible keep 1.8bar at redline??:mischeif:

now i only got 1.5bar redline

[Jonas_R]

Don't think that is possible, I believe the turbo will explode

[Jonas_R]

My Dynoplot for comparison. That was with 1,7 bar peak and 1,4 bar redline.

[newsh]

I think max for an RS2 turbo at redline is 1.4Bar ?

[Rocco]

My Dynoplot for comparison. That was with 1,7 bar peak and 1,4 bar redline.

they are very different true Jonas?? why??

the tuner said me that my car shows the power like a rally car...Full boostttttttttttt

i have to make the gear changes by 5500rpm and then i am again in 3800 with 330hp

[T2Andy]

Was the 5th gear done after 5000k at wot then you would be doing 140 mph +
