Vovchandr Posted September 11, 2020 Author Posted September 11, 2020 Got a few dents removed by a PDR guy after procrastinating on that appointment for too long. It was amazing to see him work and was quite humorous to see his reaction to working on aluminum. Removing dents from the hood was... interesting. For removal hood needs to be well secured in the location to apply force to it. Obviously it can't be on the car. Had to create a stand out of saw horses, straps, jack stands, 2x4's etc and it worked. Overall not perfect but worlds better. Some areas were particular difficult. Most were on curves. Life pro tip. SECURE STUFF IN YOUR "trunk". Also i recommend the padding from SBFS
Vovchandr Posted October 29, 2020 Author Posted October 29, 2020 This discussion came up a few times during the track day. As the days progressed and I was carrying more speed onto the straight I found myself running out of gearing well before the end of the straight and bouncing off the rev limiter. I knew in theory that, thats where my limit was by doing previous calculations but this was the first time where my cluster was working right and I got to experience it in person quite a few times. Croc was asking me which rear end I have and I double checked that I have 3.62 My 6th gear is 1:1 direct drive. Tires are the Toyo R888 225/45/13. Top speed as calculated is ~126 at ~7300PRM New tires being Avon 245/50/13 put me into ~136mph as they are a bigger diameter 22.65 vs 20.97 Unrelated to that, but big fan of the first gear going to ~45mph.
Kitcat Posted October 29, 2020 Posted October 29, 2020 Vlad: you must have a pretty stout Zetec? When I last drove T-bolt, I just left it in 5th, where it maxed out at 7200 rpm's, as shifting to 6th was so momentary before downshifting again. Of course with my 15" rear wheels, my effective gearing was different than yours. But, per my Garmin, I was topping out at 115-117 mph (vs 105-107 mph in my Xflow).

Of course with my 15" rear wheels, my effective gearing was different than yours. But, per my Garmin, I was topping out at 115-117 mph (vs 105-107 mph in my Xflow). Seems to be doing alright. Supposed to be a nice build per original spec sheet but I have my doubts on it being "all there". Maybe I'm just jaded. Haven't had an opportunity to go out in a faster caterham to compare. Over the winter will send the ITBs to be rebuilt by Borla Induction (formerly TWM) and then sometime next year plan to bring it down to NC to have turbofocus take a look/dyno it. I'd be hoping for 170whp. Otherwise while the ITBs are off I might as well mock up the supercharger that I have for the Zetec and see how/if it fits.
Vovchandr Posted November 15, 2020 Author Posted November 15, 2020 Upgraded the rails and weighted the supercharger. Not sure how it will fit yet but it's bigger and heavier than I remembered it. Figured when I send the ITBs for a refresh it will be a perfect chance to mock up the SC and see how it fits (or doesn't). Duratec SC looks much smaller in comparison. That might have to be long term solution. 43 lbs without rest of accessories!
johncg Posted November 25, 2020 Posted November 25, 2020 Congrats! Can you please tell me what type of wheels those are? John
johncg Posted November 25, 2020 Posted November 25, 2020 I also have a Zetec... and have often thought about a supercharger upgrade. It seems this is something you are doing now? if so, is this something you might be willing to share information about or provide advice? John
Vovchandr Posted November 25, 2020 Author Posted November 25, 2020 (edited) johncg said: Congrats! Can you please tell me what type of wheels those are? John Those are SLR model wheels, discontinued. They are Mike Barnby (MB) 3 piece wheels with impossible to find center caps. They came in two varieties, one regular flat and one with rolled bead lip which was preferred. It's easier to buy a 7 with them on already than to buy just the wheels. Sometimes these are also called "KN". Not sure why. johncg said: I also have a Zetec... and have often thought about a supercharger upgrade.

John Supercharging isn't something I'm serious about right now but will at least mock up to see how feasible it is or it isn't dimensionally. I need to send the ITB's off this winter and I already have the SC on hand. The opportunity is there.. Edited November 25, 2020 by Vovchandr
Vovchandr Posted March 6, 2021 Author Posted March 6, 2021 This may have been a problem. Not sure how long it has been like that. Started leaking as soon as I was fussing with it. Getting ready to send the manifold to TWM for a rebuild.

Even if it will fit, it will be tight Off by about half an inch. I could possibly machine the face plate of the SC and try other tricks etc. Not sure what I'm going to do yet. Just know its not fitting direct.
Vovchandr Posted March 12, 2021 Author Posted March 12, 2021 Also after the last track day I also discovered that my left hand cycle fender had issues... Again. Second time it doesn't want to survive a track day. Last time sika flex failed. Then hardware bolts failed. This year the actual metal of the bigheads has failed on 3 out of 4 fasteners. I only have 2 spares on hand so will have to order more. I have a feeling there is something wrong with the fairing stay so I will also be replacing it. Lucky I have one on hand. Never thought I'd have to be scraping these off. New formula of sika flex held without a problem. I used a primer this time too.
Kitcat Posted March 12, 2021 Posted March 12, 2021 Superchargers and turbos add tons of heat. How will you cool things down? Turbo heat was the nemises of my ‘19 Honda Civic Type R. I could do 2-3 track laps before heat pushed it into limp mode. The cost of re-engineering it with bigger oil coolers, bigger radiator, vented hood, widened grill etc was $10-20K, so I sold it after 3 months.

Expand Cooling will be done with intercooler and I'm fairly certain PowerWorks SC is also cooled by engine coolant. I already have an oil cooler in place. SC should run quite a bit less hot than a turbo. Either way as it sits now, it doesn't fit. Would likely be a fit into an SV for anybody curious. Right now I'm going to get a consult and look into feasibility of shortening the runners drastically (By an inch?) and potentially proceeding that way in the future.
Vovchandr Posted March 13, 2021 Author Posted March 13, 2021 Started installing the black latches. Not looking forward to drilling rivets out and/or losing them in the frame.
wemtd Posted March 13, 2021 Posted March 13, 2021 28500 miles. my fender mount broke when removing this afternoon. I think that was probably over due...

I don't think I've seen others with it. The one next to seatbelt. Same on other side.
wemtd Posted March 13, 2021 Posted March 13, 2021 Simultaneous inertia belt anchor? i think Caterhams from the ?90’s like KitCat’s old car {my first 7 drive} had both 3 & 5 point harnesses installed.
Kitcat Posted March 13, 2021 Posted March 13, 2021 Mine just had the 3 point belt. I did track days that way for years....
Renottse Posted March 14, 2021 Posted March 14, 2021 The rattle from rivets in the frame irks me no end, don’t know if Nigel at Caterham was having a bad day or I got a Monday car... best of luck Extracted so far ...
