Lotus 7 S4 1974: light restoration and modification
Discussion
I don't know how I missed this thread first time round, well done. You've taken a truly hideous looking car and made it very nice indeed.
Personally I think the front of the rear arches would benefit from some black or carbon stone chip protection to break up the orange but overall I think it looks fantastic. You have a great car collection

Thanks for the feedback. Some black stonechip protection is coming on at some point. For now I will just use the car. All mods will be done in the winter. Might do a zetec conversion, but then again the Sound of this xflow is just fantastic! I smile everytime I lift of the gas. So much bangs and pufs. Love it!
Just a test with my mobile. Press to play
Anyone have some feedback on the zetec and choice of induction. I realy would like the rough rally sound like the xflow.

Boing!
Any more thoughts on fabricating the wishbones? Will you rose joint them?
Farlig, did you get the Hi-Spec brakes?
Regards,
Mick.

yep got them fitted & bedded in despite the atrocious summer we're having this year. I must confess the brakes are very good and the car stops on a penny, but I'm still not happy with feel... My main aim at going up in disc size, piston and pad area were to try to get better feel on the point just before lock... Unfortunately I have not succeeded and It's still very easy to lock up when braking hard and I can't find the point just before to modulate... They're not wooden anymore but a long way off what I'd like...
Knut,
I have a standard 2.0 zetec on Jenvys and a Raceco, so I can maybe try to make a recording for you if you want...?
Would really prefer a twink though to suit the car better!
Cheers,
Neil
Wishbones will be welded up by tubes, just like the ones pictured earlier in the thread. Should be easy and it looks like it is the standard methode for the locost builders. It wil also fit on the original chassis without modification.
Not sure if I will do it this winter though. Roll bar is probably first up..

Do you have any bias adjustment?
Not fitted - I've upped the rear cylinder size to 22mm to try to shift the rears into doing a bit more work, but this is a temporary measure until I get a rear disc setup working... I have a bunch of bits but looking like there is a clash with my wheels so I've delayed the project to winter to keep driving this "summer" out... I'm still very tempted to order a bespoke Ti axle from Force

I'm still very tempted to order a bespoke Ti axle from Force You do realize that a larger master cylinder will increase the pedal travel and need more pedal pressure don't you?
The Caterham "uprated master cylinder" that most people refer to as the bigger one, is actualy a smaller bore.
(Think of the pressure of a high heel shoe exerts on the ground, as opposed to a Brikenstock sandal
)So if you want the rears to do more work, you need a master cylinder with a smaller bore. IIRC the master cylinder to piston area ratio is about 6:1 ?
So you need to match those with your callipers/slave cylinders.
Appologies if you alredy know all this! I'll
Funny you should mention Force, I've been thinking about the big chunk of iron called a De-dion tube
But my rear brakes project is starting to move, so I'll hang on to the pennies for a while.
Regards,
Mick.
Hi Mick, yeah eggs and all... Sorry but I wasn't too clear, I upped the wheel cylinder size of my rear drum brakes... I'm halfway through putting together a set of rear discs for my English axle but having some clearance probs... Hence a cheap pair of wheel cylinders is a halfway house... Single MC at the mo, but giving serious consideration to a twin setup after I get the rear discs working
ETA - I believe the updated MC (AP) CC sell is actually a larger bores size (13/16") hence it gives a firmer pedal / less travel / more pedal force... This is allegedly more suitable for the upgrade to 4 pots with a much larger piston area in the calipers...
EATA - we can join forces on Force (scuze the pun) and get them to make the first versions & set up supply of titanium De Dion tubes, and English live axle tubes, I'm sure there will be a market on BC and in the Escort / Cortina world

Mate, you´ve done a good job.
My way would be to restore the car in shape as original as possible (clamshells, wheels, colour, RHD, engine), but that´s not a criticism of your way. You worked hard, thumbs up
I looked at the original route in the start, but I know i would not be satisfied. I use my cars hard, and dont mind If they brake or have small impacts. If i went original/concourse route I would just not use the car as it was ment to(in my hands)My way would be to restore the car in shape as original as possible (clamshells, wheels, colour, RHD, engine), but that´s not a criticism of your way.

Mick & Farlig: you guys have too much money. Titanium rear axle.....

Twincam is oldschool. I want power! Please get some sound/vid so I can evaluate
Hi Knut, Here you go sorry it took some time & really sorry about the quality - it's just a quick one handed shoot with the iPhone... I tried going up & down a bit with a bit of overrun but it's hard to hear the exhaust burbling due to the wind & it's a reasonable quiet Raceco...Still, bit of nice induction roar
The Jenvy's are on K&N filters & there's a Raceline exhaust manifold otherwise the engine is completely standard.
Unfortunately this vid reveals how terrible my gearbox ratios are - must get a new one from SPC!!!
You've got a pretty nice set of ratios - do you know what box you have?
ETA - Here's another one, again apologies for quality - I have run you tube image stabilisation so they're as good as they'll get ;-)

A bit off topic, as we're talking Xflow and Zetec, but as we're talking engine sounds, how about a Millington Diamond ?
