| I
have received quite a few emails from people who have heard that I did a
crossram to "Stealth EFI" conversion. This process will soon be published in an upcoming issue of Mopar Muscle. But I added a few pictures to the photo page to show a little of this conversion. I intentionally left out a few pictures and some explanatory text, because of the upcoming article. |

This is a
really cool customer's EFI car.
It's a third generation 6.1 Hemi, stroked to 426", and running custom F and B 6-pack throttle bodies. The car was shown for the first time at Carlisle. |

FAST XFI Hilborn Small Block |
Here's the car. Notice two trophies ... |
||||
|
Hilborn type EFI really benefits
from going sequential. This customer ran bank-to-bank first. He noticed the popping that can occur with a stack type intake because of the random injector timing. Also, a few cylinders were a little lean because the fuel distribution block was not ideal (we didn't make that), this meant the timing had to be backed off. After we helped him switch to sequential, the popping went away, and under individual cylinder control he was able to richen up only those cylinders that needed it, thereby allowing the timing to be set where it should be. |
Bank-To-Bank | Sequential | |||
| Timing | 26 degrees max | 34 degrees | |||
| Fuel Distribution | Not adjustable | Richened 4 cylinders | |||
| Street Mileage | + 5 MPG improvement | ||||
| ET Consistency | +/- .03 | +/- .01 | |||
| Race MPH | 105 MPH | 108 MPH | |||
| Race Temp | 190 degrees | 170 degrees | |||

| This
is the 71 Challenger Convertible that won Best
Of Show at the Mopar Spring Fling in Van Nuys California
last week. It's an amazing car. I built the 528 HEMI (~700 HP on dyno without NOS), and installed and tuned the EFI system. The XFI ECU also controls a 150 HP nitrous shot, and it has traction control, and I used the XFI "flex fuel" feature to convert it to run on E85, and it all works! |
