As long as you don't turn left I think the motor does fine. First thing that breaks are the half shafts, but a lot depends on the tires.

I have had only a single halfshaft (CV joint) fail on me, the bearing cage disintegrated on a fairly hard launch, however I abused the hell out of it first.

Motorhead-
You've mentioned several times that you think the intake manifold is inefficient. Have you tested it or is this gut-feeling? Also, you did know that there are two different 2-valve intake manifolds, correct? The US model intake has smaller diameter tubes and a narrow "U" bend/throttle body setup. The Euro S motor [dual distributors] has much better pieces. Sounds like a fascinating project; post some pics when you can. Good luck! N |

Sorry for the delay I've been busy. I do know about the two intakes. Holy hell the throttle body and elbow are bigger on the euro motor are better. If anyone wants a euro intake or dual distributor let me know I have both. I know atleast the american intakes are flow limited I've seen the dyno number extrude honed intakes etc. for sale. You can also easily say it's my opinion (and I wouldn't be remotely offended) but I'm completely confident an intake with that many bends, not to mention the stupid VAF, and the lack of trumpets or whatever at the overly small plenum intersection. I'm sorry but I refuse to believe their isn't a lot left on the table. Especially since the intake ports are so nice and straight. I know with the correct cam etc. these heads can breathe to plenty high of an RPM. Also, I haven't seen anyone mention it here, but with a turbocharger setup you can vary the boost some with rpm. Say the heads fall off up top some, just have an electronic boost controller ramp the boost up a couple more psi at the higher rpm. At those piston speeds it's harder to detonate anyways. Thanks all for your comments. I will post some pics soon as I start to progress more. Oh, this is retarded but thought some might like to know. I'm sealing my intake with oring grooves machined in to the bottom of the flanges.
