MG MGB GT V8 Factory Originals Technical - RV8 headers lead to hot feet?
|Guys, do the RV8 headers cause the driver's feet to get particularly hot? I'm thinking of putting some in, but then I looked closely at an installation and it seems to me they kind of wrap around the footwell. That'd be no fun; the car's hot enough as is.|
|I have run a 4.9 with the R headers in my 72 roadester & I have not felt any extra heat at all!!!!!|
|I agree, that is not something I ever heard mentioned. If you are concerned about it you could just add some insulation to the wheel wells. The thing that will make the wheel wells warm is the big honkin V8 superheating your enging bay..|
They are far engough forward, and there is plenty of air space/movement around them. So it isn't a problem, most of the heat comes from the tunnel area.
I wrapped mine with fibreglas insulating tape, asw they came very near the brake lines.
It's kept the engine bay cooler, but there is a lot of heat buildup around the gearbox area, the exhaust pipe passes under the box, tried lagging it also, but the chrome gearlever surround still gets very hot when standing in traffic.
Soundproofing the footwells, and transmission tunnel has helped, but I still notice a temporary heat buildup when stationary, which takes a couple of minutes driving to clear, it's not engine-bay heat, as I've got louvres in the bonnet and you can see the heathaze when stopped.
|Michael, huh, that's helpful info.|
Do you really forego all that much power with the block-huggers? ... especially if you have 'em ceramic coated first? Maybe I'll just have mine Jet-Hotted and stick 'em back in there. I don't like the idea of my feet roasting at traffic lights, and I really don't like the idea of potentially cooking my brakes or tires.
Don't know, I pranged the MG and bent the block huggers against the chassis rail.
MGB Hive were selling a full stainless system for less than I paid for the old mild steel hugger system, so I had to go for it !
The stainless system sounds much nicer than the old system and the engine seems to pick up a little faster, but maybee it's my immagination.
The downpipes do run close to the brakelines and tyres, but no smells of burning rubber yet!!
last year when we drove to MG 2001, though eastern Montana day time temps were around 100* F. No problems with hot brake fluid (spongy brakes) or tires. Well maybe the tires were a little warm, but it was from the road, when you got out of the car, the asphalt (in parking lots) would stick to the bottom of your shoes! Inside the car was a little toasty though, but at those temps and no A.C. most cars are. I just opened the cowl vent and it wasn't to bad.
