Tom --- I'm not on instagram but if you could ask him for his info and send to me I would appreciate it so I can reach out to him next time I am in the area.

Thanks.

Re: Bit by the supercharger bug

I have seen this guy a bunch at C&C in Great Falls. Truck sounds mean. After looking over the install my guess as to what driveline components to fail first would be:

Tranny, CV's...then a bent crank in that order...

Sending massive amounts of Tq through an AWD system that was not designed for an error factor is not good, and not cheap.

Oh, if you add 22 inch cast leg irons on there I expect you get less than half of those launches (at least this guy is running stockers)...before stuff starts slipping and bending, internally.

Damn man, big downer type post. Very pessemistic. If you take a look over at the other threads for RIPP Superchargers they are running at 5-6 PSI which is keeping the power below the specs of the tranny and other components.

Maybe you didn't mean to come off how I received your comment, but other post I have seen from you come off similar. I am by no means an expert on this stuff but please find some more info on the product below.

No worries have been following those threads with keen interest, and contacted them, just saying that repeated drag strip launches, for the weight, something has to give. Even the mighty SRT is not immune to physics. Highway rolls - no issues and even track time, but launches are tough on non-forged internals.

Would running at these lower PSI and power outputs help avoid those failures? I guess you are saying at some point, if at anypoint, these compnents would be the ones what could fail?

Re: Bit by the supercharger bug

The 8HP70 Transmission is rated at 700lbs/ft torque.

ZF 8HP transmission - Wikipedia, the free encyclopedia

There is an 8HP90 that is rated at 1000lbs/ft (or therabouts). I can't find the article, but IIRC the innards are physically the same as the 8HP70, but made of stronger materials, so (theoretically) drop-in upgrades may be available either in parts or entire transmission form.

Half shafts and CVs were strengthened this year I thought as well.

Of course as power goes up, reliability goes down. It will all come down to the weakest link. However, if the part is being used within it's design limitation, it's installed correctly, maintained properly, and is not defective it will hold up.

There's quite a few big power SRTs out there (WK1 and WK2) that hold up quite well. I'd be willing to bet that 600hp is well within the limits of the drivetrain platform.

I will say that I am worried about the pistons on these beasts. The low-drag type pistons with the thin upper ring lands typically do not hold up well to supercharging. Just ask the GM-LS folks who have broken ring lands from even a little bit of detonation (LS series engines typically run a bit hotter on the rear pistons, so you'll see #7 and #8 with chunks missing). Basically the tune needs to be extra-safe on timing and meth injection isn't a bad idea either on a stock bottom end.

Personally I'm watching the RIPP supercharger threads closely. I like the design and the approach....might be a customer once they get a tune for long tubes ready.

Just my .02 worth.

Re: Bit by the supercharger bug

They will be making a tune with long tubes in the near future. I have talked to Ross about that because I have a set of American racing headers waiting to go on and he has the same ones he will be putting on his Jeep after they get everything under wraps with the stock set up.

I spoke with Demon and they are going to be trying the internal swap. Sounds promising.
