HarleyFDMD Posted January 4 Share Posted January 4 What power are you hoping for with 6870? I guess the stock engine will be the limiting factor. I still find it crazy that these engines will cope with 700bhp stock even after 30 years Quote Link to comment Share on other sites More sharing options...

I still find it crazy that these engines will cope with 700bhp stock even after 30 years Hoping for 700whp, but will see where Map Daddy Mike feels it's safest. He seems confident and the engine is still pretty healthy for it's age with no smoke or concerning knocking or tapping. I might get Mike to remove the launch control though as the stock engine could do without me being a big kid. I've probably used it around 5 times, but everytime I feel a sense of guilt. You're right though. These old engines are a true testiment to a time when the engineers built these cars and not the suits fixated on profits only. 2 Quote Link to comment Share on other sites More sharing options...
Dieter Posted January 5 Share Posted January 5 We drive the coolest cars you can buy for that kind of money, they're paid for, parked in a garage and getting more expensive by the day. 3 Quote Link to comment Share on other sites More sharing options...

Big Supes Posted Monday at 09:17 PM Author Share Posted Monday at 09:17 PM Inlet and DBW is in, wired up and the car is running. Had a bit of an issue on first start up. It was cranking, but not starting... and then it let out a big backfire. I thought to myself "well, fcuk. That's interesting lol". I checked a few things, but couldn't see anything glaringly obvious, but suspected it was a trigger issue as it was getting fuel and spark, but you could hear it was combusting out of time. I checked over the cam sensor wires, but again, everything looked fine. I reached out to @Mike2JZ and he kindly dialled in to take a looksy. Mike checked the trigger scope and asked if there was a chance the front and rear sensor plugs could have accidentally been swapped around. I said I couldn't rule it out as I had extended the wires meaning they would no longer marry up to their original locations from the loom. He did a quick test and swapped the ignition timing around and flipped it 180 degrees and we gave it another go. Boom! She was alive! Map Daddy came through like the legend he is. With the car running, it was quickly time to undo that and start getting the turbo off. I've offered up the new 6870 and it's not a lot of work to modify the downpipe from the 4 inch flange to the cone reducer flange to fit the Precision. I've had a brief conversation with Lee at SRD and will be ordering the flange tomorrow. I'll probably order two as I need one for the current recirc downpipe and another should I make another downpipe for a screamer configuration. 3 Quote Link to comment Share on other sites More sharing options...
Peter P Posted Tuesday at 07:03 AM Share Posted Tuesday at 07:03 AM Nice. Good to see Mike and the team at SRD came through diagnosing the issue. I like the nickname as Mike is a Map Daddy for sure. Look forward to seeing updates and following your progress. 1 Quote Link to comment Share on other sites More sharing options...
