Just to add a little more feed back. Rowan fitted up VL400 coil box several months back and used a set of AEM (IGN1A) coils on his L67. The car produces 460+ RWHP @ 21PSI using a M90. With a NGK BPR6EFS13 with a standard gap of 1.3mm there is absolutely no spark break down at all at full RPM. Rowan ...

No piggy back, all the sensors are separate to the ECU.

Thanks for the links Antus I will have a look. He is using the standard 2 wire GM water temp sender and a the VR 2 wire air temp sender. We can set up a calibration file to convert the temps using a basic 1k Ohm resistor. I just thought is anyone knew what they used in the Delco I could cheat and us...

Ok here is a strange question. Helping a friend setup a remote logging unit and it is proving to be a pain in the bum. Using the GM water and air 2 wire sensors we need to add a resistor to them on the 5 volt line to be able to add another wire as a signal wire. Now my question is, does the DELCO ru...

Sorry I thought this was on the L67!!

Good to see you come over to the dark side and now running E85!!!!

Some nice gains there!! Looks like there could be more to come by tailoring supporting mods? Yeah, now it comes down to what else has been done. I am doing an exhaust on Rowans car this weekend and he has fitted the BW cam. I think his barrel cooler will run out of flow, but we are going to shove s...

What throttle body did he use. Did he port the inlet to the blower also? I saw a great gain from a stock ported one and the ls1 throttle body, this one appears to have a better design from the start. He uses a 100mm throttle body, and the blower inlet is 100mm also. Best to just get one off him. Lo...
