Stroker twin turbo

I have built 2 twin turbo small blocks. One was a 360 LA with 7.8 compression with ported iron heads and 2 T-04s. This one would run on pump gas with low boost but we always ran it on c-12. It made 600 pretty easy with 600lb/ft at 13 pounds of boost. It took forever to spool up because the motor made no power n/a. It had its issues with one of the turbos coming unglued at speed destroying the motor by feeding it parts of the turbo. I rebuilt it with a set of zero deck SRP forged pistons for a C/R of 9.25:1. I feel that its ok to use a higher compression if you can keep it from detonating. We have used alcohol injection with great success. I guess my point is, when you run more compression you can run less boost to achieve your goal. This has multiple advantages, one is the base motor makes more power and can spool the turbos faster.Two the less you compress the air the less heat it will produce and that will help with detonation. Three, turbos typically are more efficient at lower boost levels and produce more power per pound at lower levels than at higher levels of boost. Four, power production is multiplied by percentage, if it makes more base power it will show up exponentially on boost.

The second motor was a 340 with 2 t-60 turbos a 15 pounds of boost and made 880hp at the rear wheels with a stock block and no girdle or block fill and it made over 150 passes with no issues what-so-ever. I would not hesitate to make that kind of power again with a stock block. Turbos make linear power and are easier at big power levels than say nitrous or supercharging. Nitrous comes on with a pressure spike that is incredible and instantanious. Supercharging puts a sizeable load on the crank and main bearings from the load of the belt turning the compressor.
