Triumph TR7 V8 Hill Climb car

Post by Deuteronomy @ Tue Jul 21, 2015 12:07 pm

This is the current spec of my Triumph TR7 V8, I'll update this tread with progress and plans.

This car was built specifically for and campaigned in the BARC NW Centre Sports/Saloons Car Championship for the past three years. It ran in Class D.

Specification
Genuine TR8 front subframe
Safety Devices roll cage
Rover 4.6 V8 Engine, fitted with Stage 2 heads
Holley 600cfm "double-pumper" race carb and Edelbrock inlet manifold.
Megajolt Lite mappable ignition system
Wheels are 8x16 inch, fitted with 235/605/R16 slick tyres.
There is also a set of wet tyres (210/605/R16), also fitted to 8x16 inch wheels
Front suspension is Bilstein damper with 6 inch, 2.25 ins coilover springs attached to a Rover SD1 front hub, SD1 bearing and custom spherical bearing top mounts
Front brakes are lightweight AP four-pot calipers
Wilward front/rear brake master cylinders, with adjustable brake balance bar
Rear shocks are AVO 1.9 inch coil-over conversion
Quaife limited slip differential
The half-shafts have been modified to enable the fitment of 5-stud SD1 rear wheels
Rear axle has a rear disk brake conversion
Lightweight Aluminium Radiator fitted with twin electric fans
Single wiper conversion
Safety cut-out switch (battery is relocated to the boot)
Plumbed-in mechanical fire extinguisher (+manual fire extinguisher by the driver's seat)
OMP Race seat and Willans 6-point 3-inch race harness (valid until 2017)
Full tubular stainless steel exhaust system including manifolds

I'll add pictures soon, but esstentially it looks pretty wretched at the moment with a truly awful colour combination/paint job.

Leaving out the stage 2 4.6 engine, how much do you estimate that list of parts would cost if you went out and bought them today?

I'd estimate 277 bhp/t at the moment, I'd like to get this to around 330.

I'll not save much more weight but current power is probably about 250 with MASSIVE torque - I'll keep the torque and up the power to 300 bhp. Weight is about 900kg.

Sans engine, I'd say £15k+

My plan is to strip the whole car down and put it back together again. Properly.

I'll change a whole load of stuff too, like I'll bin the carb and fit fully learning fuel injection.

Don't think you've mentioned before but do you have any experience hill climbs or racing? Looks like your starting near the top in terms of speed (in road legal car category anyway) I'd have started more cautiously with a shitter.

On and off yes - I've done some circuit competition and enjoyed it, no hill climbs though. But with hill climbing I only really want to see how fast I can go and how good I can make the car. No doubt I'll get smahed by everyone else in my class but I only want to race myself, if you follow me.

Right, see how fast you can make the car go. What if the red mist descends though?

It's brill, but an absolute shit to get in and out of. The seat is fixed and I need to adjust it as the previous owner must have had arms like Mr Tickle. I prefer to drive with my arms bent so with either have to fit a runner or removable wheel as I'll not be able to get out quickly in an emergency.

I don't trust removable wheels and a runner increases the seat height by about 15mm - being tall my head is already touching the roof with my helmet on - will have to experiment and see what I can get to work.

irrelevant nonsense


Look at that little panel left of the seat. It seems to have switches & lights. How fab is that! What the hell do they all do? I want to play with them...

Ignition, fans, fuel pump, lights - that sort of thing Monts.

Admiring the effort and shredded knuckles that await you in taking it apart and building it up again. I am simply not anything like as dextrous or patient as it would take, though I would love to do it one day.
It had better go fast enough to outrun a black hole once you're done!

Will you keep the bonnet bulge without the carbs or go for a flatter one?

Looks like another awesome build. Your threads about your old cars remind me of LotusNova and his project. The pace might differ slightly but otherwise they're pretty much the same!

Shit the bed!

I've just done a little research on the AP Racing calipers that are fitted to it, they cost £1440.00.

Each!

Good news everyone, I've found a suitable wheel and tyre size.

It transpired that wheels and tyres were harder than I though they might be to source in the right size. Ideally I'd go for 16's but they seem to the the lost wheel for a good tyre selection.

So, 15's are the way forward and a lot more period. Lots of tyres but hardly any in the 265/40/15 that I need for the rear, but happily I've found a set of DMACK (they do the tyres for the WRC) road legal semi-slicks in 265/40/15 for the rear and 225/45/15 for the front.

Should I wish to I can easily source a set of full slicks as well in those sizes.

After measuring I can get Minilites that will just clear my massive front discs/calipers. As an FYI, the 'technical help' received from Minilite is probably the worst I've ever had. They are a disgraceful shower of shit and should be embarrassed to know so little about the wheels they make.

I'll get these ordered over the next few weeks, I'll need to have them drilled to suit the SD1 hubs that are fitted to my car.

Due to arrive today are a set of front pop-up lights and an NSF wing to replace the badly messed about one that's on there currently.
