I need Rotary Help

[David88vert]

Have you seen Mustangs that run 10's? Tires are in the air.
Launching isn't about stressing the driveline. It is about efficently getting the maximum push going forward.
Here is some info you will probably enjoy: http://www.baselinesuspensions.com Check the "Launching a Drag Car" page. Good info there. Kevin Slaby is a very knowledgeable.

Again, the engine is producing the same torque and stress on the driveline from either engine when at the same output level. It doesn'nt matter whether the engine internally has oscillating pistons or spinning rotors. It doesn't matter if the engine spins a crankshaft or an eccentric shaft. The bottom line is if the engine is putting out 330tq, it's putting out 330tq. 330tq is not more force coming out of one motor because it's a different engine type. There is no denying simple physics, or common sense. So a piston motor at 500hp is not easier on the driveline than a 300hp rotary - because the horsepower has nothing to do with it. The torque is what breaks and twist things.

BTW - I am very familiar with Grannys. A friend of mine has a 2nd gen vert with a 302 that I have spent some time on. And you are right that the TII driveline holds up pretty well. He has TII driveline, and takes it to the track occasionally, but he is only pushing about 350rwhp.

As for V8s - I have a supercharged 302. It's slow. Don't think that all V8s are fast.
I also have had many Rx7s and have a FD right now. It's slow also. But exactly as fast as the V8, but with less hp and tq. It is more fun though.

If you want to see a mid 10's run with no launch - watch any Supra at the track. Sorry, I couldn't resist. :-)

guys... the man isnt trying to build a drag car. He quoted somthing that read "heavy flywheel" and metal clutch. Hello, I dont think this guy is going to have 15" wide slicks and a metal clutch. NA drivetrain sucks major monkey nuts any way you slice it. I had a GTUs (N/A drivetrain) with a TII motor swap, the trans is the first to go in that situation, the rear second. If he wants speed its a full TII swap or V8 w/ that engines trans + TII rear and custom shaft. People have supercharged the crap out of the N/As and only seen 250hp. Bolt ons should suffice untill you have the bank for big upgrades. My sugestion is to enjoy the car untill you have the money to go buy a decent S4 TII. You can by an RTEK for that bitch and go crazy from there.

No one was talking about N/A driveline. The same physics apply to any driveline.

There are N/A's making 300hp with no poweradder btw. Check PR P-ports. Of course, they don't live very long.....

TII driveline is definately the way to go. There is no disagreement on that. My only comment is that it doesn't matter what engine it is to the driveline.

Oh yeah, and a 20B > your V8....
