Does anyone know the history of the Superlight for sale? Says it's an import but there's no plate on it.

Heard the rumble, looked up and you were headed up Broad St. What a great day for a blat

Your green 7 with black stripes was paired up with another 7 in red heading west probably wondering how best to dodge the rain around 3.30pm today. Both cars looked great btw.

Wow that is a lot of pork pies!

Out of interest how much do you need to budget for a F190 coming from a Sigma 125 VCT? There's bewger all stock currently for sale with that power so weighing up options?

Re #11 I bought a xflow engine which had similar characteristics. Once rebuilt it turned into a cracking engine. Re #12 indeed it is. I can easily see £5k required to bring that car back to reasonable condition as it needs repairs and a full repaint. And I haven't been underneath it yet.....

Thanks all for your comments. I visited PT for the first time today and it's clearly a thriving race prep operation - Ian is a very knowledgeable and helpful guy. It appears they sell many cars on behalf of customers who want rid with minimum investment in bringing to showroom condition. So while the R3/400 has had its engine refreshed, it hasn't been set up on the rolling road which means no test drive until that's complete. Any buyer will need to specify the state of tune they want and commit with a deposit and the rolling road will follow plus cosmetic improvements. It's got a great spec but probably too great a leap of faith for me at this point. Note: while I was there they took delivery of Superlight R #76 which is being put up for sale if anyone's in the market.

Hi all and hope folk have had fun blatting today. I've become feverish and fitful with level 3 withdrawal symptoms and need to get into a 7 again. Does anyone know this car here? It sounds a bit tatty from a previous post and seems it has had a history of losing power which doesn't inspire confidence but could form the basis of a sound car. Did anyone on here own it? McB

Thanks all for your comments. Car runs Valvoline VR1 20-50 mineral oil. I can confirm oil pump is both high capacity and high pressure as per receipt from Burtons. As for what happens at 5,000 rpm I need to take her out to explore and confirm but I'm pretty sure the gauge shows 3.5+ bar so maybe I'm getting cross eyed for nowt. It's just the 1 bar at idle that concerns. Could the oil collector be too close/far away from the sump floor I wonder? Is there an optimum position as I recall the engine builder had to raise it a tad? Car is going to James Whiting soon so perhaps he can test with a mechanical gauge.

On my 1760cc Xflow I'm getting just under 3 bar on cold start up at idle, then just under 2 bar on hot idle. I've also noticed the oil pressure light takes maybe 10 seconds to extinguish after start up. When cruising at 2500-3000 rpm I get 2.5 bar, When returned to base after 20 mins, I get only 1 bar at 1,000 rpm. This is scary but oil pressure light doesn't illuminate. Oil level is at full mark on dipstick with no discernible loss. Gauge is standard Caterham, not mechanical. Engine runs a high pressure oil pump and rebuilt only 4K miles ago and not tracked nor ever taken to rev limit. It's due an oil change but any thoughts as to why I'm seeing such low readings?

Ray, I have a 96 Xflow 5 speed and the reverse light wouldn't work but I came from underneath the gearbox and found the reverse switch housing had worked a bit loose. I managed to tighten it back up with a 19mm open spanner and it started working again. Might be worth checking this as well. McB

Update: I've replaced the front brakes and braided hoses using the Eazibleed which was much more straightforward than I imagined. Thanks for your tips. The only issue I encountered was excess fluid in the reservoir after I'd bled all the brakes so I syringed it out to reduce the level to max. In future would draining it by one of the caliper bleed screws be just as feasible? Pedal seems good but off to the MOT on Tuesday so I'll know if it's all been worthwhile.

Wow great information guys thank you. The gauge read fine with full deflection so I removed the sender from the tank and moved the float over its full range, cleaned the sender contacts and reassembled. And bingo gauge now working. I may renew the rubber seal for good measure. I spoke to Chris at Redline who likely has the part if anyone needs to renew. Thanks for your help.

John, Thanks for your comments. Yes it's a Caerbont unit with 1/4 sweep. Re testing the gauge, I assume I do this in situ and with power on? I've got twinned green wires, one black and one green/black (plus the separate lighting circuit) so I am shorting the green/black to black? Re the sender yes it's a top set device with separate high level feed to an external Facet fuel pump. In terms of quantity before I added the 10L I think the needle was showing just above the red. I'm not sure re unusable quantity however but it's an S3 chassis. Do you know if you can just buy new seals as I can see the old one is cracked around the edges?
