Name: James Murray
Vehicle: 1968 Ford Cortina II estate
Engine: Rover 3.9 V8. 9.35:1 Real Steel cam
Injection: Offenhauser 360 deg manifold home converted to port injection with own rails and Vauxhall injectors. Custom throttle body from pair of Sierra throttles.
Description: I've been running the car with the Rover V8 since 1999 and with 150hp of nitrous and a Holley 390 it ran 12.8 1/4 mile. Cold start and town driving were pretty poor. EFI fired up fuel only on Extra 024s8 using the wheel decoder as a tach input. Within the week I had the car on the track and running normal numbers (14.3/97 no nitrous, 13.2/103 with an empty bottle.)
Update: Now runs coil packs for wasted spark ignition driven direct from the MS using VB921 IGBTs and Extra code 025i6. Have wet manifold nitrous control and launch control running.
Update2: Added a second stage of nitrous using "Output2" with an rpm limit. Added more fuel by bumping up the VE values above that rpm and taking out timing. New best 1/4 mile ET 12.33 @ 110mph
