Thanks for sharing the fun Doug, I really enjoy your films. That course looks pretty intimidating, lots of much worse places to spin than the one you chose. Look forward to seeing the inside of that engine and next year's car take shape.
That was pretty exciting stuff. I've often heard those engines were capable of a lot more and you've certainly tested that, Davri engine sounds very interesting. Thank you.
If you stick with that diff ratio, slightly taller tyres might just be enough as raise the gearing. Being able to do most of the course in 3rd could cut your times.
The 750cc Reliant is only putting out about 50 bhp (based on the vehicle mass and the 1/4 mile times of about 17 seconds). The Standard Reliant 750 had 32 bhp.
@@DougsShed that’s not much, especially when they could do about 70 or 80 BHP. I would, I would’ve expected it to do way more in terms of horsepower. It must be a pretty low compression ratio. I know people put these in Austin sevens, I can’t believe they getting such low figures.
@@mrjed6912 The tuned Reliant 750 engine has a race camshaft. The power band does not really start until after 4500rpm. Would not be pleasant to drive in a road going car.
@@DougsShed, where do you get speed equipment for an engine the size of Fann Wong’s waist? It’s not that Edelbrock or Crower sells it. I heard that the engine’s a cousin of the Triumph Herald/Spitfire engine, so can you use the latter to bore and stroke the former and use aftermarket speed equipment for the Triumph?
@@chrishenniker5944 Due to the age of these Reliant engines there is very little available for tuning. Performance camshafts are about all. The 750MC race series used to get a lot of experimental/amateur built race engines. The 850cc versions had to run pretty much standard specification.
Fantastic sounding engine at full song, had no idea they were that capable,
The Reliant engine can be made to 'sing'!
That was a real learning experience. Good luck getting the diff repaired.
Hi Lloyd, I will probably put the 4.9:1 differential back in. Especially if I keep the standard Regal gearbox.

As they say "watch this space"!

Pushed the simplex timing chain a little too far I think.
@@DougsShed The self rotating air filter is still doing it's job 👍
@@niallsommerville9941 I think I will 3D print some vanes to make it really spin
Awwwwwe
Make it live again . thanks for your vids.
I'll try!
Chears from France jeep on racing ❤
.great stuff....gotta share this !!!!!!!!
You're welcome!

I think the 4.9:1 with the Regal or Robin standard gear ratios should be fine.
What modification are done to this Reliant Engine?
Darvi dry sump system, race camshaft, lightened rods & rocker gear. Standard distributor on points & coil ignition. Single choke down-draft Weber ICH34 carburettor.
@@DougsShed Thanks!
@@DougsShedwhat sort of power and torque are you putting out from this Reliant?

what if you put this in an actual Reliant 3 wheeler?
Better just to use a later 850cc Reliant engine - much more drivable on the road.
@@DougsShed Would the drivetrain fall apart?

This is an opportunity to put a more modern, more powerful engine in. Say, a Ford Zetec or Chrysler Hemi.
Ha Ha! - The Jeffrey is a tiny car, an MG Midget engine & gearbox would fit at a squeeze.
