My new Lotus 7 Replica

hi, guys

I've been hanging around here for about a year now, watching Croc's ongoing list

and looking for the right 7. I think I've found it…that funny turquoise car from a few

weeks back. I'm calling it a "replica" because he built the frame and sheet metal with

supposedly original Lotus 2/3 plans and then installed a Cortina GT drivetrain (1970)

with the crossflow head (so a 2 1/2?). I've just received it…can't even drive it until I

get the Weber rejetted for my local elevation (4300 ft). But I'm pretty stoked! I have

a bunch of questions already, and I hope you'll help me out getting my feet wet...

but first just wanted to share early pics with everyone!

Thanks for all the nice comments. About the color, it's not a color I would have chosen/expected to work

but oddly enough, it's a popular color here in Sedona. The local McDonalds even have arches that color.

Plus I'm hoping it will look "friendly" to the cops when they catch me having a bit too much fun.

 

I managed to get a short blast around the block before the plugs started to foul (running very rich at this

elevation)…and the car is even more fun than I remembered. I'm smitten! (and my TR6 is feeling insecure)

hi, Tom

Pretty cool you're so close…and yes, 89 would be fun once I get up and running! (btw, my brother lives near you in Carefree).

Since you're in essentially the same climate….want to field a question? This Lotus doesn't have a choke, and also isn't running a

thermostat (just a plate with a small hole in it). My first impulse is to get both choke and thermostat…and for that matter

add a thermostatically controlled fan instead of the on/off switch. However, I'd like to know what you're doing…what's working

for you? I'd appreciate any thoughts...

My Superformance S-1 has a 160 degree thermostat (a new one) but I am having trouble with it running hot (at least indicating hot, it doesn't boil over) but I think it is an air flow and not water flow problem. The cowl intake is very restrictive on the S-1.

 

A washer instead of a thermostat is old school hot rodding solution, simple and once you determine the correct hole size, dependable. I don't like them because it takes forever for your engine to warm up because the water pump is always sending enough coolant through the radiator to cool the engine under the most extreme conditions. Causes the engine to run so cool that the intake won't heat up enough to warm the fuel air charge for good mixing. I'd put in a thermostat.

 

Has the choke plate been removed or just wired open? Is it the old single barrel carb or the dual?

 

Let me know if I can help.

 

I live just 2 miles south of Carefree and another S-1 owner lives in Carefree.

hi, Tom

I appreciate your comments. In my case, it's the dual throat 32DFD carb and the choke plate has been completely removed (!) I agree with your thoughts

on the "hot rod" trick and not warming up quickly…even more of a problem at this elevation (cooler weather). I'll definitely get a thermostat…also waiting for

new Weber jetting in the mail. We'll see how it goes. And thanks for the offer of help…I will surely have more questions *grin*

hi, Tom

sorry I'm late in responding, apparently I still don't have the "notice by email when you have post" working yet.

Very kind offer, I appreciate it. I think that 1970 Ford Cortina GT's came with this carb (32 DFD) and

they had a single choke plate over the primary. If you happen to find one that would be great, but

please don't go to any trouble. I've since rejected the carb and it's running much better. A choke would

be a nice thing to have, but I'm finding I can live without it. I also got a 160 thermostat installed per our

previous conversation. Tomorrow the motor gets an oil change (just turned 500 miles since the rebuild)

and the valves adjusted. I'm loving the car…thanks again for the offer!

It's typical with webers that a few pumps of the throttle pedal is all that's needed. Weber chokes always tend to flood the engine.

 

That's a very nice car you have there. With that configuration crossflow, it's very similar to a Lotus Series 3 seven. The front suspension has a lot of the right caterham/lotus bits, even if the fiberglass isn't quite right.

hi, Dingo

Thanks for the carb info…I was talking with Pierce Manifolds today and pricing

the parts to complete the choke assy. FYI it would be about $50-60 for new

parts, but based on your comment I'm going to let it go. It's in the high 20's

here and I find I can still start it with about 4 pumps (which is amazing). So

there's that. Good eye, btw…the front end bits are all Caterham, but the frp is

Curtis Unlimited. I think the builder was going for a 2 1/2 style and that's why

he went with the downdraft DFD. Curiously though he had the dual Weber manifold

and included it in the sale. I'm going to just enjoy the car for a while, but may go

with the DCOE's in time. I'm open to suggestion on that, if anyone has comments

pro or con. I assume a bump in power, but wonder about the added complexity.

Also I'll only be driving on the street so probably have no need for the power.

They look great though (!)
