165 MPH, 18 PSI = boom

af61r is very nice. i cant argue abut the power numbers, cause i have np proof, and sure as hell no way to prove it now. in reality, whether it was 400 or 500 isnt particularly important to me compared to the overall area under the power curve and the acceleration of the car, and it accelerated very very fast. i will definately dyno the new setup once it is broken in, but i dont expect to start buying parts until march or so, so i'd say a fully running, broken in engine wont be until late april. i guarantee that the new setup will make over 500 peak hp, with a relatively flat power curve, as that is my numerical goal. like i said im not real impressed with dyno numbers, but you gotta have some kinda goal to shoot for, and im convinced it can be done on pump gas with the right tuning and engine build. i guess this one just didnt meet those conditions.

I believe port timing is the same for both S4 ans S5 T2. Although I wouldn't rely on just the S5 rear iron. I cracked mine and the car was only running 10psi.. must of hit some slient but deadly detonation.
Well guess its just gives me an excuse to rebuild the motor with an even bigger street port.
Mine doesn't seem to be as bad as yours though, just leaking slightly. Still holds good oil presure.

You have to use the later S5 ('89+) TII rear sidehousing as it has a reinforced rib cast in from the dowel area to the oil filter boss.

Port timing for primary ports are DIFFERENT.
This is all detailed in the FSM's.
The S4 primaries open 10-degrees EARLIER, so the S5 primaries are technically "smaller".

hmm...maybe i should weld together a 3/8 or 1/2" aluminum oil pan...that might not be a bad idea, dowel pins too.... and that pic isnt quite like mine, i broke a whole big chunk out. my o2 is about 12" back from the turbo outlet. i wasnt looking at the wideband, since i was going 165, i was watching the road.
