wow wow wow wow..... heres a pic of a 15lb boost 8 rib setup they did for an ess vt-500, still using v3si!!!!
New bespoke pulleys to achieve c. 15psi boost. These are now for an 8-rib belt, rather than the old 6-rib one, which should help prevent slipping at high rpm...
im going to call them about knocking me up a 10lbs setup.. tom youve inspired me, its time to leave Ess behind and go forth with our quest for power, the hard bits are in place now, but i do think the cooler needs to be upgraded, as will the oil cooler, radiator!!
just look at those pulleys!! lovely lovely!! |
Wow. That would be nice upgrade. Do you know if they had to move parts on the e46 to clear the 8 rib pulleys?
In my other post i said vac mls 0.7. It is a VAC Motorsport steel multilayer gasket 0.7 above oem gasket to raise a the engine head and decrease a tad the compression ratio. I know that it is pretty common on other engines to run safe +15lbs just with a higher head gasket.
Congrats for the award. |
Very cool idea in regards to the headgasket.
As per your question about boost, my boost isn't maxing out because i'm on a custom, 2.87" pulley which is coated to not slip, but still slips. Too small, but i got a really good bump in midrange boost
Originally, i had a less aggressive pulley setup than Bdubb, so my max of 7psi was correct for the sizes. Measure your crank and supercharger pulleys and compare them to the chart i posted before
