Re: Peugeot 205 GTI 8v track/sprint car

Time for an update....
I have a new exhaust that's nice and quiet at around 93 decibels. It's a bit of a monster to get the noise levels right down
I also had a map top-up by Steve and Steve at Track 'n' Road
The results (ultra accurate) were:
150lb/ft @ 6229
185 bhp @ 6850 (flywheel)
Result in 77.6 lb/ft per litre, 192.4 BMEP and 246.6 bhp per tonne
Here's the graph
A full write up and more pics on my webpage here
It goes so well it's incredible! It's what you'd expect from having 80% of peak torque for a whopping 4700 revs; now that's a seriously good powerband.
I have compiled a quick video of the mapping.

Now onto fix a few niggles and it's track time..

So before I can get out and drive the car in anger, there are a few issues/improvements to make, some mandatory, some tidyup, the list is:
Mandatory stuff before next track day:
1 - Improve Oil Cooling System - Currently I am running an air to oil cooler with a removable jacket. This system isn't working well, as even on the road the oil isnt getting over 60deg C and that's too cold. Plus removing the jacket is a pain in the bums, and even worse is the oil change is a knuckle skin remover.
So Guy is helping me implement the following system:
Remote Filter housing with larger filter
Thermostat to control flow to oil cooler (or not)
With everything re-located I will have a much better layout allowing easy oil changes and be able to get better oil temps
2 - Stop oil leaks
My new cam cover is leaking even whean sealant is used, to it went back to QEP this week to sort out, either flatten or build up and skim
3 - Improved oil breather setup
I need to perform more testing, but I think even though the car is breathing significantly better (according to steve greenald) the catch tank can fill up quicker than expected. So i'm designing an air/oil seperator with a drain back to the sump, and intending to make it myself with my new tig welder. So I will need my current sump to have a drain plug fabricated.
3 - Sort out binding front caliper
4 - Sort out speed sensor, clearance must have changed as it's not working half the time
Optional stuff going forward:
5 - Fabricate proper bulk head gromets
6 - Tidy-up wiring in engine bay, I haven't had time since getting it back to ensure the proper heat shielding for wiring is in place, and keeping wires secured away from alternator etc
7 - Fabricate new display - Remove secondary oil and water displays, and replace with a new dash display that receives it's feed from the DTA ECU. So rather than need duplicate senders, I need only 1. Lighter and simpler. This is the new fully configurable display that will make it's way to compliment my new display.
Here is the display:
So going from this (current):
To this mock-up:
8 - Make the grill quick release - as it comes off so much, changing the fasteners to r-clip type fasteners will make life easier.
9 - Fit new fabricated fuel rail. The fabricatyed one had a small pin hole in it, so I got the mended version back this week. This will tidy up the fuel hosing a bit
10 - Fabricate new brackets for oil cooler and grill - self made
That should keep me busy for a while
