it works on a race fiat 1500cc alloy blocks one of our clients at work come and got some 0.6mm stainless mig wire to use for his block which was being machined for it at the time,it worked perfectly and he hasn't had a problem with blown HG's for 2 years now
1500cc fiat 14.5CR N/A

Does your client run without standard HG or HG w/o-ring? If without, does he/she run a dry deck or o-ring the oil/water passages?

hell of alot better than i coulda said o wet one
and from what i know o ringing involves cutting a groove around the cylinder
and then installing a wire of some size jast just a few thousandth of a inch above the deck surface
btw since we are talking about killer motors the vnt turbo is sposed to arrive on the 7th...
wootness now to find someone to weld cast iron or i can attempt it i spose

I ran across cylinder o-ringing back during my first go-round with turbos... back in the mid-70s. Most people then either went dry-deck or used separate o-rings for the water/oil passages. They were also doing it mostly with castiron blocks/heads (usually in the head, IIRC), and using copper wire (better crush).

Northwet, thanks for the heads up on the management. Exactly what control does this setup afford? Also, why MAP over MAF? I've heard the opposite is more tunable.
