Main thing with an electric pump on a race car would be to keep the coolant circulating after the engine is turned off?

 

[stevyg]

You drive that thing on the road? lmao that's awesome!
An electric water pump frees up rotating mass on your engine for that little squeeze of extra HP. For a race car I'd use one that is a constant speed at whatever LPM flow Vs air velocity you need to get max cooling across the radiator (too much or too little flow does the same damage) so its consistent and not speeding up and slowing down with RPM like a conventional water pump. It's so much more reliable and can keep water circulating after the engine is off. I've lost 2 new race engines from a belt coming loose and overheating and cracking the block in a matter of seconds so I switched to inline electric water pumps and I've had no issues since.

Thats the plan!

Yeah it was a popular mod with the bike engined crew where squeezing the last few HP out of the engine was difficult, don't think i will bother on this car tho, just something else to plum in and draw electric, my 40A alternator will struggle enough!

@IL I seem to recall you posting a photo somewhere in this thread of another TR7 in the white/blue/red combo. Do you know them? I spotted it on the back of a trailer today on the A75. It was being towed by a grey Porsche Cayenne too- couldn’t believe it!! At first glance I thought you must’ve been busy this last week!

 

[Gambit]

TR7 went through bloomfield auctions last night for parts or repair.....for £70

Yes, i've got a screw loose lol worst man maths ever building a TR7..

Hi Ian, that is a very common works colour scheme, done on many TR7 across the UK, it was my original plan to do the car like this but there are so many poor examples i decided to keep it plain!

But.. it could also be an ex works car, A75 (stranraer?) There is an ex works car lives on these shores but around Ballymena..

i was wondering if it was you maybe bought it being local to you

Yes outside Stranraer. The Porsche had a plate beginning N1 which I always associate with someone from NI, so could well have been the Ballymena 1 over on the mainland. Who knows!

Last bit of Drive train now built and ready to Install..

Earlier today I received the custom input shaft, it took almost 4 weeks to arrive due to a heat treatment backlog, so the home brew Bell housing is now complete

It allows for the standard flywheel with integral crank sensor, i've adapted to it run on a Saab Type concentric slave cylinder.. thanks to @sam_9n for the machining work, top class service!

Remote Bleeder.

Rear mount, Powder coated & bushed.. All ready to slot in place next week

 

[FM155]

Good stuff, you down at Kirky tomorrow? Looks like good weather, hope you have a good day at it.

 

[sam_9n]

Nice! You may get your homer orders in, I’m back on nightshift

 

[IL]

Yes, I was down today, they had already tight restrictions in place for Covid, limited numbers, no spectators etc but the event was cancelled mid morning a lot of work put in the midget over the last few weeks for no return

Nice! You may get your homer orders in, I’m back on nightshift

Good man, I might have two small packers I’ll need made for the rear mount and a one for the prop but need the box in to measure up

Going to try and Wrap this up now the racing season is over..

Seems a bit surreal to be finally putting some liquids in the car, Fresh Castrol B373 into the Tractive & a batch of RBF600 for the Brakes and Clutch!

4 attempts at putting the box in on my own was testing, found the twin plate clutch plates where now perfectly aligned so got them realigned with the old input shaft..

Got there in the End, so fired in the starter and manifolds to check the routing for the clutch line..

Oil, Fuel and Water plumbing are all pretty much complete.. Another few fittings in the post will complete it

I cant believe the To-Do list is finally becoming achievable!

 

[FM155]

God I love this thing.

 

[IL]

God I love this thing.

I’ve a Love / Hate relationship going on with this girl!!

 

[FM155]

I can imagine tbh but it is just such a brilliant interpretation of the old TR8's .
Be great to see it out on a few sprints and hills.

What an immense amount of progress since I was in lifting the engine looks absolutely class.

It has really worked in my eyes, well the ingredients, yet to be proven!
Pity it gets thrown into the libre saloon class due to the engine swap

Its getting there, fully operations Brakes, Clutch and Hydro is the plan for Today!

Really need to get the Wiring man Nailed down to a date!

 

[svensktoppen]

In fairness it really is a libre saloon, not much Triumph left

Brilliant wee thing, should do well regardless

Personally i think it will be a smoke machine lol and probably very hard to drive with the power in a short wheelbase but I’m up for the challenge...

The post man has just been with more parts, back to the Garage

 

[EF Ian]

More greatness. Not far off now.

It might surprise you, my RBZ did, its only got an extra 14cm over this and it just digs in and goes, so much that the front end raises quite noticeably. And thats with running 490lbft.




Nice details:

Nice details:

Are you comparing to Standard TR7 wheel base? i've this stretched by 5" so they will be pretty much identical..

The NA lump should provide more progressive power delivery and only around 400lbft.

Nice of you to notice the details, its lovely installing all the little covers that took far too many hours..

 

[GT_MAXER]

Ye

Yea and match coolant to revs or restrict to a certain rpm/flow rate.
This is just glorious. What a build

Its the details that make this build for me.

Stunning work as always @IL
