Sold.

Selling my Bilsteins as ive upgraded to Quantum Two Zeros. They've come off an R400 Duratec SV. Fronts have been on the car since it was registered in 2008. Numbers on the springs are:- Fronts: Eibach 40/07 Caterham cars 75517 Rears: Eibach 27/15 Caterham cars 74076 Both rears were replaced by myself approx 3k miles ago, one of the old dampers was leaking so i replaced the pair of them. Rears are in very good condition and clean. Fronts, as you would expect, have a small amount of tarnishing but none on shaft of damper which is 100% clean. Happy to send specific photos, please pm your email address and I'll send, but Ive posted some photos below to give you a look. Not looking to split them unless I find buyers for all. Looking for £450 for all four dampers + springs. Delivery can be arranged at additional cost (£20). EDIT: Editted because the forum doesn't like mobile phones. :(

It was at the fly. Steve G and I had a conversation about it. ...or to be even more clear. When Steve pointed at the bhp , I said 'thats at the fly yes?'. He replied 'you're one of the few to get that right'.

I was searching for something similar last night. Try this thread : https://www.lotus7.club/forum/techtalk/which-new-6-point-harness

Yep I have the ford sierra diff too. Access via boot is much easier for me than attempting yoga positions from below. I also used the Redline MTL in my gearbox. Definately an improvement. :)

R400 Duratec. 2008. 23k miles. Roller barrel throttle bodies. Dry sump. De-cat. 214.5bhp and 159.3lb/ft at fly. Very happy with that considering Caterham say 220bhp with RBTB. :) Ps. Sorry about formatting.. forum doesnt like mobile phones apparently.

I had issues at low rpm too. 2450 or thereabouts and the engine would sound 'off'. Kind of hesitate, struggling. A fair bit of kangarooing at low speed when trying to trundle in slow moving traffic. All gone now though. Re. Fuel filter, i believe its in the tank but dont quote me on that.

I hope this thread helps. :) https://www.lotus7.club/forum/techtalk/wing-mirrors-options-instead-flappy-ones-side-doors They are fixed into the stanchions, i know youve said you read some posts on them but these completely solved any issues for me.

As promised... here is the update. Took the R400D to the two steves at TracknRoad tk have it remapped. Prior to arrival I fitted a new set of BR7 spark plugs gapped at 0.9mm (I found a post on here saying Steve G recommended them. Also found one from Aerobod with loads of good info). After remapping its like Ive got a different car. Massive increase in throttle response. Like.. night & dsy levels of difference. Loads more urgency and pull from the engine when you squeeze the throttle. On RR it hit 140mph so I know the gearing is capable. Ive not been able to test top speed on circuit yet but I have absolutely zero doubts its going to be much higher than before given the new sense of power. All credit to the two Steves. They know their stuff and as far as Im concerned... money well spent.

As promised, latest update is that its going up to two steves at track n road for mapping. Likely to be about a month before I update this thread again unless i find something new.

Yep. I will definately keep you posted :)

In case anyone else needs this info in the future. run a logging session tonight. friend and laptop in passenger seat with laptop plugged in with easimap 6 running. lambda fluctuating up / down around 1.0 mark. at full throttle lambda was ignored, engine ran rich at this point. throttle sites moving smoothly from 0.0 at idle to 15.1 full throttle. consistently smooth readings. tps from 4.64v at idle to 0.8v at full throttle. again, consistently smooth readings duty cycle never higher than 50% even at throttle site 15 (full throttle) (not sure this is too low?) spoken to two steves at track n road. getting it booked in for a session with them, other than the duty cycle, which only appears low to me but i dont know if this is normal (green injectors), im struggling to see anything immediately wrong.

Thanks for that Scott. Gives me a bit of reassurance im not imagining it. :)

Thank you very much. Thats information i can definately understand. I'll plug the laptop in and log it. I know a stretch of private road. Im located just outside Bristol. Bit of a drive to the two steves but im not opposed to it.

Oh and air filter was washed in hot soapy water. Will be re-oiled with K&N oil once dry.

Cheers Paul. Tps is at 4.64v , as close to 4.62v as i could get. Load sites go from 0.0 to 15.0 How do you check fuel pressure under load? Can easimap do this?

Hi John, Air filter has just been taken out and cleaned. Literally... just as in 1 min ago. Water didnt look that dirty to be fair. Car was on a rolling road for previous owner. I have dyno print outs from when roller barrel throttle bodies were installed. 193bhp at wheels. Never had it on one myself. Dont know if its been remapped. Ecu is MBE 38L036A. Can they be remapped? I thought the MBE were locked, unless im wrong. Plugs. Bosch HR7KPP33 double platinum. Aero. Yes. Whenever im sprinting or on track its always aero'd. It feels fast at anything sub 80mph. Soon as i get to 100 though its only gaining spped at about 1mph per second or less. Trying to think of anything else i can say which ive not in opening post that would help. EDIT: reformatted post on my pc as formatting was bad from mobile.

Thanks for the tips. Just checked, with aid of 2nd person, and the roller barrels are opening 100% on all 4 inlets. Air filter looks pretty good tbh although I suspect its the original one from 2008. Its the pipercross foam filter which covers all inlets. Spark plugs look a little lean if anything. Rather than not enough air. I dont have a cat on it. Took it off a while ago.

Hi folks, Just wondering if anyone else has experience of this and would care to share some pointers to help me. I have an R400 Duratec, 2008, with roller barrel throttle bodies. 220 bhp. Car will fly up to 95 / 100 mph but from then on it's slow to accelerate. Very slow, maybe 1mph per second. I do a fair amount of sprints and track days and rarely get past 110 mph. On Bentley straight at Snetteron Im getting 112 max. Looking at others videos (R300 / R400) they are getting 120+ with ease. Corner exit & speed onto Bentley is fine. BIts of info. Diff is a 3.62 (60mph = 3400 rpm or very close) 6 speed box Speedo is verified vs GPS Checking my videos back Im changing gear at about 7500 rpm Possible clues. I've checked the plugs are a couple look like they are running lean. I've asked about on FB as well, to try and get a wider range of experience. Fuel pump likely to be struggling? Any help greatly appreciated :)

Well... at least this thread will get the annual roll bar discussion out of the way for 2018...

I purchased a 2nd hand R400D with 15" wheels. I swapped them out for 13" and have not looked back. For reference I compete in sprints and do plenty of track days. Second hand slicks are dirt cheap and plenty of tire choice in new. 13"s feel more agile and imo... suit the look of the Caterham better.

Thank you very much folks! Appreciated :) I could not find them on CC parts site when I first looked.

After a nightmare few hours trying to get the front right ball joint to release, I had to resort to a pickle fork. Now the rubber cover is damaged. Is it possible to purchase these seperately somewhere? Ive looked on CC parts store but can only find the whole assembly at £88ish which isnt going to happen.
