I would have done but I fear that i might have added more than I lost with the addition of the oil cooler . Ideally i'd have fitted a smaller one but 16 row was the smallest mocal I could find with 3/4 fittings.

I removed the blanking plate i had above the rad to fit the cooler and I think it gets decent airflow in there. I also removed all of the intake duct and trunking to the air filter as i doubt it was doing a lot and space is now getting short in the engine bay.





We also tidied up the catch tank install as this had to be raised up at Brands as it was filling up with oil rather quickly Raising it seemed to cure it



John made a new means of holding the throttle return spring by drilling a bolt, we just have to remember it if we lift the strut brace

Re: DW's (new?) Sierra N/A PINTO race car

Well it definately needs a wash inside and out after the wet race at Brands, but I also have a few more little bits of weight to take out before Lydden.

Re: DW's (new?) Sierra N/A PINTO race car

the bumper looks better now dave , how much weight are you planning to take out of it ????

surely it doesn't need that much out of it

who cut the bumper and how did you get that curved edge so .... well ... curved .

I cut it. Black and decker jigsaw mate
I cut out as much as poss without it looking too ridiculous but at the moment I'm looking to remove anything that doesn't have a good use so a few more bits will be unbolted / cut off this week

Re: DW's (new?) Sierra N/A PINTO race car

or is there

Rear seat bracketry removal from me

Re: DW's (new?) Sierra N/A PINTO race car

Rear seat bracketry removal from me

You mean the rear seat x-member Dave? Not sure if the rules allow removal of it

I have a little list of things that can come off, I'll do it this week if I get time as most of them are under the car.

Re: DW's (new?) Sierra N/A PINTO race car

Not that mate, just the brackets on the tubs for the rear seats, some have captive nuts too...think of all the weight in them From memory theres one on the top and one on the front on each side

Re: DW's (new?) Sierra N/A PINTO race car

Dave.. rules state floorpan.. the x-member is a x-member not floorpan,

But its low down weight, and something that you may need if i get my way with the suspension

Theres lots of brackets and bits and bobs that can come out which are higher up.

re the seat, the rules state that aftermarket seats can be used, and suitable mounts ... suitable mounts is the key.. same as dashboards can be cut to mount cages, in series that say the interior must remain,safety first, so to safely mount the after market seat mounts the floor/tunnel needs modifying.

The fact that dropping a 10kg head down 50mm is worth more than cutting a 10g bracket out from above the rear tub is niether here or there

Dave.. rules state floorpan.. the x-member is a x-member not floorpan,

actually rules say fixed panel!

the standard floor pan, sills, door surrounds, bulkheads and roof must remain exactly as produced by the manufacturer in construction, dimension and material. it is prohibited to cut any holes or remove any fixed panels from the standard floor pan, front or rear inner or outer wheel arches, front or rear bulkheads (engine to habitacle and habitacle to boot) for the purpose of mounting or giving clearance to suspension components. Inner wheel arches may only be modified to allow the attachment of shock absorber mountings.

Re: DW's (new?) Sierra N/A PINTO race car

to safely mount the after market seat mounts the floor/tunnel needs modifying.

stricty speaking you cant! not if it involves cutting or modifying the fllorpan or tunnel, BUT theres nothing to stop you welding in more material to mount a seat, which is exactly what i did with my car, welding in one small extra bracket enabled the seat to be bolted directly to the floor in 3 points without needing extra subframes etc. that said no ones likely to get out of there box over a small mod allowing a seat to be fitted, BUT cutting x members out of a car simply to save weight isnt really on

the thing is its a clubman series, if you start pushing the boundaries of the rules in too many places your find the rules get tighter!
