We have been busy working with AET Turbos on hybrid k04 solutions, and yesterday proved to be a pleasing day results wise. Our Lupo test car, (MrsB car) is a bog std AUM engined car, just with IE rods in it. It has as supporting mods, B5 TIPs,JR Filter, B5 gen2 exhaust manifold, 2.5" pipework, a modified S3 AH V1 fmic, water meth, 3.5" downpipe, into a full 3" exhaust. Runs on Vpower.
Previously the lupo on its k04 hybrid made a bench mark 372bhp/320lbft torque on our dyno. This was already an exceptional power output and one few others have equaled. A tough act to follow.
We specified a new level of hybrid, with the experience we have on these things over the past 6+ years now, it was worth a punt to see if there was anything left to be able to extract out of a k04 hotside/frame turbo. 372bhp already making GT28xx size turbos obsolete for these power levels..
What AET have been able to build, based on a K16 full size turbine wheel, clipped, and new even larger 7+7 billet compressor wheel, in a custom compressor cover and intake. Pictures and test data below.
As pictured uses our existing V2.2 Billet TIp adaptor on housing so 80mm TIP can clamp direct to it.
The Lupo Install.
First run on Actuator Pressure. (14psi) - A very promising 331bhp.. That bodes well.
Now time for some boosts and mapping.. After some fiddling down of previous duty cycles we got a very nice 402bhp from 23/24 psi peak boost.
Exceptional EGTs for the power output... Max of 840'c -
comparison to its previous hybrid, 372bhp vs 402bhp.. Nigh on same boost levels between them. Significantly faster spool on the AET K04-380 unit
Prices and "Package" options will be published shortly, as AET and I discuss and finalise details. The Package will comprise of our Gen2 High Flow exhaust manifold, The Port Matched to our Gen2 manifold K04-380 turbo, and our V2.2 Billet TIP pipe. (our Gen2 manifold not available separately).
From AET's published info, the tech spec of the turbo is as follows:
We take a custom K16 turbine wheel a 7 deg cutback to turbine exducer to increase flow through the turbine housing.
Before the fitment of a K24/2280 billet compressor wheels, CNC machined compressor covers to accommodate the hi-flow billet compressor wheels.
An AET motorsport spec 360 thrust assemblies is installed to cope with increased boost pressures.
Total seal piston rings fitted to the turbine for low back pressure exhaust systems.
Ported wastegates for increase boost control at hiboost, and ported turbine inlet for increased air flow
a 14psi Turbosmart IWG75 actuators fitted before being VSR Balanced to motorsport spec.
