I've almagamated this with the 'head gasket repair' thread as the project continuing in there didn't make much sense - so page two is the place to head for updates! :)

Well, this is rather fun. No long journey, no road trip, just a short ten minute drive after a last minute bid sees this sitting on 'the lot':

It's a 1974 Triumph Dolomite Sprint - a real early one, non overdrive 4 speed, with a full-length Webasto sunroof.

Reputedly it was being prepared for rallycar useage - It already has K&N filters, Facet fuel pump, twin front calipers, lowered and uprated suspension, plus I suspect it's got an LSD and quickrack - so by all rights and means it's a pretty well sorted car and also benifits from a nearly-new MOT and long tax.

So - what have I learnt about it. Well, I took it for a quick spin today.........and it's hillarious!

The steering's hard, the ride's hard but it's very comfortable, the clutch bites like a trooper (I don't think it's standard, clamps up so hard), the accelerator's hard (although that's easily fixed), the gearshift is stiff, requiring deliberate action to smoothly engage gears - and it pulls like a train


You put your foot down in 2nd from idle and there's a gentle pause as the HS6s draw deeply through those wide K&Ns, hoovering up the underside of the bonnet and suddenly it starts to gain pace. As it climbs over 1500RPM the rears break away and it just starts to rev, rev and rev. Ease off, get the power down and it scoots along gathering speed at a fair whack! Lights up the tires with ease too which is great fun.

Interestingly are the brakes. This has the twin caliper 'upgrade' to the front struts. The pedal is very soft and heavily assisted for a Sprint, with the first few inches of travel having a very gentle effect. As you hit the remaining travel, however, it suddenly bites and the damn thing stands on it's nose. So it brakes hard, too. The handbrake works brilliantly too......Grab it, locks the rears, twirl the wheel and suddenly you're in an episode of 'The Professionals'.

It'll be interesting to take it for a 'proper' drive and see what they're like on the road. I'm only running it up and down the drive at the moment, as I'm not insured on it - just keeping it warm and running it through.

Also a bonus - it looks like it should leak like a siv but even in all the downpour we've been having for the last week, there's only a slight drip from the corners of the windscreen inside. Result!

I need to ascertain whether it does actually have an LSD or not - at the moment, it's certainly acting like one but I need a bit of clean tarmac, as all ours is dusty. It seems to launch on both tires though, instead of one.....but I can't say for sure. I'll have to jack it up and spin the wheels.

Had a good poke around underneath and only found one very small hole in the underside of one sill, the rest is extremely solid and just needs a good brushing over with some new underseal :) It has a newish MOT and lots of tax so it's no real urgent issue but I'd prefer it to be sorted rather than not.

I just want it loud, noisy, brash, full of gauges and switches but most importantly - fun. It's a real driver's machine and incredibly involving. Rev it up to 2500, bang the clutch out, rears light up, floor it and away. Makes a real good noise.

I'm not sure what to do with it at the moment, really. I kinda like the way it looks at the moment because I don't know, seems to be a bit of it's character in it's visual defects. Does need to be a bit lower though methinks and a little cleaner. Maybe a matt or satin colour would suit it...

Oh, it could be a bit ......lower though. I'll just have to make a bash guard for the front underside and move the brake and fuel lines inside :p

It'll be getting a side exit as well - primarily to ditch a bit of weight but also to get rid of the crossover pipe that sometimes clashes with the axle. Should sound a bit more bomber like then too :D

Suggestions and ideas for what it could become are welcome!

Lower :p You really want that for speed bumps? I am guessing it's lowered 1"?

Anything done to the engine or you think it's a stock Sprint setup?
 
It feels like it flat-out hauls, that's about all I know! When I switch my insurance over I intend to get it rolling roaded and see what's what. Don't know what it is yet (will get it off the ground at some point) but it's very firm :)

I can drive over the speedbumps on the other drive and it just thumps across them at 30mph without even touching anything :D

Could well be it's just a good example of that engine and I doubt anything internally has been done - it just goes very well, pulling strong and hard with no hesitation to 7000. Makes a right racket (but in a good way!).

Oil cooler, additional instrumentation, better ignition and some cooling modifications are about all I will do to the powerplant for the meantime :)

I couldn't say - I'm only running it on a short drive at the moment - but from a standing start in 2nd gear I was doing 55MPH with a good thousand RPM in reserve before I knew it over a very short distance - and had to bail at the junction! :D

Like I said, when I get it out on the road I'll get some proper figures. It feels quick, for sure :) Whether it is or not is an entirely different matter - but in this instance, I don't care! If it feels fast, it's doing the intended job and having the effect I want!

Standard these are ~120-130BHP and 60 in around 8 seconds :)

Go get your dori dori on and turn it into a drift spec Dolly, boro style. Sounds like its half way there already :D

Was just thinking the other day, i have literally never driven a corner in a dolly not sideways :)
 
Soo.........Time for a little update.

The car's been sat for a while whilst I've been working on other projects so hasn't had much TLC yet. I'd been busy fettling the 1500 (new weather strips, refurbished wood, tuning and so on) to the extent that my friend decided he liked it so much that he wanted it. So I sold it to him!

I'll be posting a little writeup regarding the 1500 FWDs when I collect my thoughts.

Turning back to the Sprint, I looked to address a low-speed running issue - effectively, it'd suddenly become very lumpy and feel like it wanted to stall. However, on running it up after a long way this was now manifesting itself as a complete cutout at random. I checked the fuel then moved onto the ignition - on removing the distributor cap, I found that it had Luminition Magnatronic! Another score!

However, someone hadn't fitted the wiring very well, causing it to chafe and rub on the rotor, presumably causing the cut. I swabbed out the distributor, gave it a good clean, refitted the ignition module and wiring with new terminals and loom and fired it up. Now starts on the first turn of the key and no stumbling, hesitation or cutouts. Sorted.

Next, with my slightly 'racy' intentions in mind, I set about installing my Autometer rev counter. These do not only make it clearer to the driver what the engine speed is, they are also much, much more accurate and precise than the Smiths equivalent - they do not overshoot wildly or wobble, giving a clear visual. With their air-core actions they also have a nice quick sweep.

This particular unit also has an integrated shift lamp, which activates at a user-set RPM, giving a clear "OMG CHANGE!" warning to the driver.

I wanted a nice, clean intall without cutting holes in the dash so I made up some underlying bracketry and reinforcment to secure the gauge over the central speaker position - cutting holes in the expendable grill instead. With that done, it was simply a case of wiring it up - a good earth, splicing into the gauge illumination circuit, a switched 12v feed for power and of course, a signal feed from the tach or coil. This was all promptly terminated, cable tied and insulated away out of harm's way.

I did have a bit of a fracar with it for a bit - Autometer's instructions stipulate that you MUST cut the brown and yellow 'configuration' wires for a four cylinder application. However, doing so led the gauge to over-read by twice the engine speed. After much fiddling and voltmetering, I mucked around with the brown and orange wires, finding that leaving the brown wire connected left the gauge reading correctly. Great instructions, eh!

All done, I gave the balancers a quick fettle on the carbs to bring the idle up from a rather sluggish 600RPM to a much more sensible 800RPM. No more hesitation or stumbling when coming off the throttle hard now back to idle and a good strong pull right from the word go.

The finished result (excuse the mess of HU wires, unfinished stereo install):

Makes a good impromptu rear view mirror as well!

Very pleased.

Also noticed that primer has the same consistency as a chalkboard and at the time was using a chalk marker to note my observations on various parts and mark some bolts.

Cue shamelessly cloned scribbling :p

:D

Anyway, onwards!

Expending to the list of modifications, it now has braided brakelines throughout, the aforementioned Luminition ignition and a polybushed ARB. Next thing I need to do is a fuel pressure regulator and filter.
 
Oh and these are the themes that are running through my mind at the moment......Although the 'desert' primer is starting to appeal as well.

No decisions yet, mind. Just a thought.

I actually like the paint on that SX, with the "anti glare" panels and the red stripe as seen on the SR-71.
