Right time for the final instalment!!
As I mentioned previously, a vvc engine is mapped backwards in comparison to the conventional way of building up the rpm and mapping through the load sites. This meant that the engines potential would be seen within 6-10 dyno pulls.
Scoff then set the rollers in motion and it was game on. So what you need to keep in mind is that the high ambient air temps on the day and in the dyno cell obviously have an impact on power. Also worth noting is the R3 engine is quoted as 230hp and 180lb/ft. Anything within 5% of this figure is deemed acceptable by Renaultsport........
On the day, the cup managed to pull 229.9hp at 7700/7800 rpm and we saw 181lb/ft of torque. And not a set of itbs in sight!! Mission accomplished. Here's the video I took of scoff doing his thing and getting that 229.9 dyno pull:
Hard cut limiter is set to 8k rpm and the idle speed is set at 1600rpm - the cams dictated this as they're a bit lumpy! Lol!
So I guess that's it. This chapter has come to a close now for me, but there's a few people that can't go unrecognised for their help along the way.
First off, I've got to say a massive thank you to Scoff @ EFI. He's really done me proud on this. Next up its thanks again to Sean @ ktec. Without him, the vvc wouldn't have been working to its full potential like it does now.
@BIGASH has to get a mention for his utter confidence that we would see some good things from this engine, and also being at the end of the phone to listen to me rant! Lol! Get packing youth - we've got a trip to Germany coming!!
@Dan@SJM for assistance on the mapping when the piece of s**t wouldn't run and no one could fathom out why!!
@not normal dan another one who's tried to talk sense into me when I'd happily have panelled the car!
@nath&alex another legend who's been on the end of the phone and sorted out some awesome stub axles.
And finally the biggest thanks has to go to the wife. I've lost countless hours to this project, yet she's been there at every step of the way.
I am as they say, Romeo done. :up:
