0-6 in 6 sec? I can beat that on my bicycle!  |

It isn't bad for an Aurora. I won't put a stall converter on my car n beat up the trans. Watch any other automatic n compare. I believe factory is 9 sec.

Nm factory is 8-9 usually closer to 8.

I count about 7.5 sec to 60 from that video, which seems about right. I can't see an Aurora doing 0-60 in 6 sec without some fairly extensive modifications.
Did you go with an X or H pipe?

I was told that x or h is only for sound and they run better without mixing the pressure waves. It was about 6.4 on a breakdown with windows movie maker looking at the frames.
It's like 5.6-12

I have a Shelby Series 1 motor, and a Cold Air Intake, then the duals.
I plan on checking my cams when I get time to pull the valve cover, but I've been told that they put egr block off plates on when they messed with the crate motors. Since they didn't run a egr. Mine had the plates on it.

The factory converter will allow a 1,400 rpm launch, but don't hold it long it is bad for your trans.

Very nice! It sounds very different.
How difficult was it to get the true duals in the, uhm, awkward area? EG right beneath the engine, haha..

Welded the threaded flange where we could get to all four bolts. Then changed the doughnut gasket to one with a pipe inside to prevent collapsing. Then it bolted, threw away flex pipe, and it was all bent solid. He's a killer mechanic, I usually consult with him. He has a 7,200 rpm 350 78 Camaro, with 11-1 compression.

Got any underside pics? Would really like to see how you pulled this off.

I have an O2 simulator in the post cat plug, and I wired the sensor return lines to the bank 1 sensor 1 on the sensor 2 plug. That is the one before the cat. So my light isn't on.
I'm trying to upload the best one I have, I'll get a better pic next time I get a chance to get under it.

I wonder if the stock 4.0 can sound as loud as that!
Your Shelby Engine sounds very healthy and muscular.... it wants "moar powr"!!!

I'm curious why you rigged up the O2 sensors that way instead of just hooking up real ones in the original configuration (one per bank, none post-cat.) Without proper feedback, how is it going to run at peak efficiency?

That one is irrelevant only trips mil for emissions. The front two are doing their job. I didn't put sensor 2 back because I didn't need that sensor with its added cost every time it goes bad. I really didn't want to put an unnecessary hole in that beautiful pipe either.

Sensor 3 is post cat and on a simulator for post cat.
Bank 1 sensor 1 and bank 2 sensor 1 are in there.
There is 4 total. On OBDII

Looks great, sounds great, too. Did you bypass the pipe that goes between the motor and trans, or is that part of it? |

Post by shelbyracing on Mar 16, 2012 7:14:01 GMT -6
Thanks, I wanted to do away with it but wouldn't have had much ground clearance. It does good when the pipe warms up though.

Blacked out the pipe n stainless mufflers. Then painted pipe from mufflers metallic engine block paint  |
