Mapping

I have been very lazy with updates, so a well deserved big update on the car!

Myself and Jay headed up to the dyno to see how the car was doing, but on the day as always happens there was a problem... with my boost controller. So we couldn't map on the way up. Once we got there I found and repaired a power wire that had pulled free from a crimp and all was well with the controller, or so we thought.

The next issue was if it would get on the rollers (as the diffuser is rather low)! Luckily it did and I then managed to break Jay's Datalogit plug! I thought I was all out of luck then Dale came to the rescue as he had one in the van, thanks!

Jay jumped in the car and we did a few runs, but there was too much wheelspin so we all climbed in the boot for more grip and to my astonishment we got a massive 650hp with 500ft/lb of torque!

But... it was slow to build boost and it fell off too soon at the top end which Jay says is due to the boost controller. I am going to check the spring in the waste gate and also the lines to the waste gate as it could be one has a small leak.

Even so I'm really pleased with what we got, and there will be more to come soon... once the boost controller is setup we will re-run on the dyno and post up a graph. Cheers Jay for the build and your help!

Here is a video of the run I edited on my phone: Video of the dyno run





Custom canards and splitter

Since I didn't make the pod due to man flu I thought I'd update the build thread!

After all of the engine and suspension modifications I hadn't focused on the aero since adding the rear wing. I'd also damaged my front splitter, After all of the engine and suspension modifications I hadn't focused on the aero since adding the rear wing. I'd also damaged my front splitter, so it was an ideal opportunity to balance the front of the car and help reduce front end lift. I decided to make a twin canard setup which links into the front splitter. The splitter runs all the way back to the sub-frame and mounts to the chassis and front bumper. Roll on testing!



Rear diffuser

Following on from the front splitter I decided to build my own diffuser for the back of the FD. I always liked the RE Amemiya one I had with vortex and and bowtech generators, but I felt the car needed something more substantial to keep up with the rest of the aero.

After numerous photoshops, sketches and cardboard engineering I settled on a multi fin design with large vortex centre fins. I kept the angle at a range so flow wouldn't separate, and designed it to work with the rear angles of the car and the exhaust for a one-off design. I finished the design in aluminium and HDPE with a blow over in black. Its securely fastened to the underside of the car using a number of bolts and metal brackets.
