I got the shifter bracket back at the 11th hour and the alterations weren't quite as specified. I decided I'd try and fit it anyway and had a dispiriting few hours last night trying to thread it all together. Very late on, I managed it.
I put it all back together this morning, but had to improvise on the catch tank location so I could drive down to JBS for the rr run. I didn't have time to do any logs - I decided I'd just hope I'd got it right. Car set at T9 HB9
First RR run, it ran 268 bhp. James commented it really needed / could take advantage of advanced timing.
Second run, I pulled the fuse on the water/methanol. 295.2 bhp 265.9 torque. I'd like to have seen 300+, but hey, not bad for a DIY job.
James said he thought the hardware was right and that he reckoned he could find me another 30-40 bhp and a lot more torque.
The big inlet does sound better, I think I've got that as good as I can. (because of the welding mistake on the shifter bracket, my side to side cable is a bit stretched. I've set it so that all the gears are fine - excepting reverse. It's a bit pot luck where you find it.
