Guest |871| Posted May 1, 2011 Report Share Posted May 1, 2011 Hi guys- This is an engine we have been using to test camshafts and other stuff on- It's a 2008cc audi 20v (AEB code cylinder head), with our own cams / springs & retainers / rods / etc. Compression is a safe 8.65ish :1, on JE slipper skirt pistons with 9310 alloy .180" wall thickness pins. ECU is the V88, which has been awesome! We have tested it out as far as 9500 rpm on the heavy OE hydraulic lifters, but with this particular turbocharger there is no point doing that. The turbo is a street setup, a Comp turbo 6062 billet compressor wheel job, with a .63 A/R T3 hot side which is choking it up top some. Injectors are the 210lb siemens deka low impedance, on VP Q16 fuel- injectors are huge haha, just in there because we are switching to E85 as soon as this drum runs out. I need to figure out how the V88 E85 sensor functionality works.

Guest |851| Posted August 11, 2011 Report Share Posted August 11, 2011 nice numbers, can i ask why so low compression ratio? especially if you are thinking about switching to E85 .. been trying to figure what comp ratio to shoot for on my engine build, had some really good numbers with 9.5:ish ratio last year, 450hp @ 1.3bar with 4 cyl 2.3l had to spend quite lot of time with the timings and water/meth to get the knocks out though when increased to 1.6bar ~ 1700mg/c airmass. currently running 8.5:1 on a 6 cyl 3.0l which doesn't seem as responsive. though no knocks what so ever..

Guest |871| Posted February 22, 2012 Report Share Posted February 22, 2012 Meh, we have done lots of them at 9:1 and 9.5:1 as well- it doesn't really pick up much power, but it does lift the head a lot easier. It also will chew up wrist pins quite a bit easier. E85 was not in the plans when the engine was built- we are just running it a lot R&D'ing various parts and the Q16 gets expensive. That engine has been through about 200 gallons of it so far- actually a fair bit of full throttle pulls if you think about it. Same engine a while later with a big, old school journal bearing T4 on it- 68mm inducer... 29psi boost. Needed more fuel pump to go further then that and we never did get around to it. I'm super excited for the plug in ECU they have coming for these engines- selling the wire in's to this crowd has been like pulling teeth, the plug in should be great.
