    Spun a rod bearing - SC Aluminator block

    Here's another thing to consider. Detonation can/does pound out rod bearings. Do you run pump gas with your blower setup(s)? It does not provide alot of margin IME. Another possible root cause. TurboTR

    Long Awaited Turbo build...

    If you're wondering about exh backpressure, just measure it. It's not hard to do at all. You'll likely have difficulty measuring much of a difference between the .96 and the .81. You will however get the turbo to spool earlier/faster with the .81, with little if any actual penalty in terms of...

    Did the oil filter relocation today

    Nice work. But man, especially for the oiling system, I'd take out the hose barbs and clamps and put in AN adapters and braided stainless AN lines! JMO. TurboTR Oiling plumbers nightmare on the street v6 Buick, lol.

    Whipple HO calibration 2006 GT

    No explanation. Combustion noises that sound like pinging are almost certainly pinging. Best test would be to run a full load of high octane fuel and see if it changes or stops. Or take several degrees of advance out of the calibration and see if it changes or stops. Assuming your wot a/f...

    Long Awaited Turbo build...

    That's part of the answer to the spool question, above. .96 is really too big for this app. It'll work but it's a bit oversized at this level, and there is a response penalty to pay for that. Personally I'd keep a single street app at .81. It would still support 1000+ hp like that, and spool...

    Can the stock oil pressure "gauge" be converted to a real gauge?

    Well I ask because older cars (pre-S197) can apparently be converted ~ easily by removing a 20 Ohm resistor and changing the sender. Assume our S197 gauges are just on the CAN bus, no? Thanks, TurboTR

    Problem with boost on the dyno

    The way they show it is the old standby "deltagate" mode. Like shown here: If I follow the thread right, the boost dropping as you describe seems to suggest the controller can't get enough pressure to the top of the wg to keep it closed enough when the flow and pressure gets higher. So...

    Problem with boost on the dyno

    Well it's maybe not the cause here, but I do recall years ago that some turbo Buicks with big turbos (back when a 76 was new and big) were dropping boost like that and it was very puzzling. Turned out that some part of the intake setup was actually collapsing under heavy air draw. Like the cone...

    closed loop/open loop

    If you mean closed loop at WOT, basically no in our case with switching O2s providing the feedback. The regular switching O2s are designed and good for one thing only really- sensing stoich a/f ratio, by telling the PCM that the a/f ratio is either rich of stoich or lean of stoich. But it...

    06 GT with FRPP/Whipple HO kit- can we get a 2.9L onto it?

    Thanks. I contacted Adam and apparently he only deals with K-B now. TurboTR

    06 GT with FRPP/Whipple HO kit- can we get a 2.9L onto it?

    Has anyone here done the conversion? Car has a Cervini cowl hood, so hood clearance is not much of an issue in my case. Seems doable with a few key pieces. The alternator is in the way. The water crossover is as well. Can the Shelby water crossover setup bolt on to fix that? And need a...

    This cam good for turbo?

    If you're running alot of boosted power, generally the exh side is having trouble getting the exh out. That's not hard to imagine. Seems it should open earlier is what it should do, not have "less duration" in general. That seems like an odd generalization, to me at least. It does make sense...
