So how does the BRM compare to the Brazilian engine you had in there before? It looks like you have more power and similar torque from a smaller capacity. Interestingly those both sound similar when ticking over and in normal use. The Brazil engine felt good, revved well - even taking into account the weight of the crank and was a very quick engine although it didnt feel 'quick' probably because it didnt increase its revs as quickly as previous engines. The BRM however feels completely different to the Brazil block engine and actually more like my original 1730. The 1730 was quite an 'Angry' engine to drive at all speeds and the BRM is less angry until it gets up on the cams and then it is a completely different story. The BRM feels a bit more drivable and has a much wider power band - or so it feels. It is definitely quicker though and i think even with a 4.44 diff it will pull max rpm in 5th. |

The oil cooler has turned up.  Untitled by Nevtiger, on Flickr The idea is it sits just below the number plate as then i don't need to cut any/much of the lower panel to create airflow. I shall make a new front chassis brace and oil cooler mount to give the cooler some protection. Some thinking to happen first and maybe even some CAD - on the computer not cardboard. |

I didnt get round to fitting the oil Cooler but it didnt matter last week at Abingdon as the oil never went over 100 as it was so cold! Prep for the event was ok other than the starter motor failing. It is a WOSP hi torque one and it's probably 6-7 years old only. Any way fitting a standard one got it going once i had enough battery power to spin the engine fast enough for it to start. Good event but a big spin on first practice pointed out the tyres are shagged....  Untitled by Nevtiger, on Flickr  Untitled by Nevtiger, on Flickr And then two videos of trying to get off the line. One with launch the other without.........  86CCF822-0529-406A-A449-FA23F181E72C by Nevtiger, on Flickr  C0F74F18-24EB-46D3-B83D-4637A8CF8AC9 by Nevtiger, on Flickr And back to the garage its time to sort out Project Number 3 as the brakes have failed......

One option would be to mount the number plate letters on a mesh in front of the oil cooler, Lotus did this on the Elan and won a court case confirming it met the regulations (every thing behind the grille needs to be black as well)  |

I know it’s not a direct comparison due to unscrubbed tyres / different temps, but it seems to gate quicker without the traction control

Oil Cooler. Started to look to see if i could get the cooler in here:  Untitled by Nevtiger, on Flickr  Untitled by Nevtiger, on Flickr After a bit of fettling the answer was yes  Untitled by Nevtiger, on Flickr However, i soon realised that although it would fit i wouldn't be able to get the pipes to it or do them up without other major surgery.  Untitled by Nevtiger, on Flickr Back to the drawing board. With the spoiler off and the chassis brace these pipes can be seen.  Untitled by Nevtiger, on Flickr Perhaps with some pipe bending and stuff the cooler could sit here? Well not the one i had bought but a less wide one might so.....  Untitled by Nevtiger, on Flickr Make some brackets and bend some pipe  Untitled by Nevtiger, on Flickr  Untitled by Nevtiger, on Flickr And end up with this:  Untitled by Nevtiger, on Flickr  Untitled by Nevtiger, on Flickr Old sump guard mounts repurposed for the third time!  Untitled by Nevtiger, on Flickr And now fitted. The bottom chassis brace/cooler mount is higher than the crossmember.  Untitled by Nevtiger, on Flickr  Untitled by Nevtiger, on Flickr Getting plumbed  Untitled by Nevtiger, on Flickr In other news after a spin at Abingdon i thought i ought to replace the tyres....  Untitled by Nevtiger, on Flickr Supposed to be same size as old tyres but are definitely heavier.  Untitled by Nevtiger, on Flickr |

Before the event at Abingdon the starter motor has started not to work.... I thought i found the problem when i found loose mounting bolts but that wasn't it. So i changed it for a standard starter. Any way got some time to strip it down and have a look see. I started on the Solenoid. These gear reduction motors use a large rotating contactor to pass current to the actual motor. When i opened it up the rotating bit and the two static bits were mucho dirty and the static parts pitted and bent. Note the big hole dent thing after an initial clean  Untitled by Nevtiger, on Flickr Way dirtier than it looks.  Untitled by Nevtiger, on Flickr Much better  Untitled by Nevtiger, on Flickr Ready to be pulled out and made better.  Untitled by Nevtiger, on Flickr The actual motor seems ok once it was cleaned  Untitled by Nevtiger, on Flickr There is a technique to getting these back together easily apparently.  Untitled by Nevtiger, on Flickr Its all back together but i haven't tried it yet...... |
