  • Newbie. 2001 Superlight in Fremont CA....

    Fellow Drivers,

    I've got to confess to being a car nut since birth. At 12 after mowing hundreds of lawns I bought my first car (71 Mini) and first saw a Seven parked in the car park at the St James hospital in Dublin (Ireland). I wanted one...Finally many years later and about 10 years ago, now living in CA, I was able to build a 7. After getting a house and family and some big debts in the post .com crash era I sold it for the cash. The purchaser was do_superlight who posted on here several times. Recently I reinforced Dave's car hobby and enabled him to buy the Vette he had really wanted by purchasing the car back from Dave and am now finally posting on here for the first time myself.

    I was a very early CA builder using SPCN.
    It was ordered before the SB100 bill was approved.
    The car is a 2001 Superlight. (Not SV)
    Zetec (VCT but not SVT)
    Built in CA but supplied with parts from Caterham USA and car from RMSCI since they were close to a place I used to visit for work in Colorado at the time.
    (I also visited the factory in the UK before purchasing the car.)
    It has all the carbon. The Magnesium center wheels. Race radiator of the era.
    Uprated brakes and wide track. The only engine mods to date are:
    Lower temp thermostat.Redline Water wetter.
    Header wrap on the stock caterham headers.
    Relocated air intake to passenger side and lighter odessey battery in center.

    So here come the questions: (Pointers to threads are a good start.)
    1)Where can I get tires these days?
    Preferably the staggered CR500s that came on the car as I liked them.

    2)What camber are people running for a fast road car with some planned track time. Car has got ~-1.5 fronts and they still seem to be wearing more on the outside even on the street.

    3)What tire pressures do people run on the CR500s on the street?
    (Currently at 18psi. Tires are wearing more in center on rears than outside edges. Have heard numbers as low as 11psi from others but that seems rediculous.)

    4)What is the source for the rubber seal against the bonnet that was used on the cold air box mod for the SVT zetec?

    5)Has anybody tried to push the zetec NA to beyond ~200HP crank?
    There has been a lot of work done in that direction by NA focus fans over the last few years that seems to have a lot of potential to the zetec cars.

    6)Specifically has anybody tried the massive speed systems cylinder head?

    Finally,
    Thanks to Magnus and Doug for great posts and keeping such a great forum going,

    Andy

    I'll answer what I can.

    1. Maybe Roger Kraus Racing see here: http://www.californiacaterhamclub.co...read.php?t=483

    Other tires maybe be just as good and more readily available. Magnus gives good reports on this Toyo R888s

    2. I use the recommneded settings from Blatchat. I currently run bias ply tires on the track and radials on the street. I don't bother to change camber as the radials seem to work fine at these settings for street use.

    3. 16-18 psi seems fine for me. Currrent street tires are Avon A021 but they need replacing soon.

    4. Check with Caterham USA as I think they did this mod. I use Jenveys to get the cold air in for my SVT. I rolled the edge over on the cutout so its not sharp.

    5. A couple of the UK engine builders claim over 200 hp with their heads and cams. Check Raceline and Dunnell. Caterham USA sells cams for the SVT that they claim gets ~225 hp. I believe someone on the list has tried this but not certain who, I'll search and see what I can find.

    6. I've not seen these heads before, what do the Focus guys claim for HP? Will they work on the Contour engine with VCT on exhaust? You may need a ZX3 engine which can be had for <$800 as a crate motor.

    Welcome to the group.

      Hi Andy,

      Welcome. My Zetec outputs 178hp at the wheels, so >200 at the crank isn't difficult these days. I have Probe 10.1 pistons, Ford Racing head, stage 3 cams, and single 65mm throttle body on a lightly ported stock intake.

        Here's the link to the guy that's getting the most from his SVT.

        http://www.californiacaterhamclub.co...ighlight=power

        See athens7

        Note he was also working on a cold air intake, this is essential to getting the most from the engine.

          Welcome.

          1) The tires people prefer seems to be are:
          Victoracer V710 Brilliant grip, but heavy.

          CR500. Available at: http://rogerkrausracing.com/pages/pricing.html

          ACB10 Cross Ply. Caterham recommends different camber, which means new de-dion ears at the rear, but Doug and others just run them with their standard settings.

          Toyo R888. I took them out on track and got the same time as my old, somewhat dried out V710s. Very nice experience, and very good for street use as well.

          There are other tires that I don't know much about. More suggestions are welcome.

          2) It was a looong time since I adjusted Camber (probably time to check it), but I think I ran somewhere around -1.5. No problems with uneven wear.

          3) I run 18 rear 16 front on my 13" V710 on track. My street/track 15" R888 get 18 psi on all corners.

          4) No idea. Caterham probably has it.

          5) I plonked a supercharger on my stock Zetec and probably got 220 out of it. Far too heavy solution, even if the engine could take it.

          6) Nope. Almost everybody goes Duratec for big HP these days. Cosworth in Torrance can give you all you need if you let them roam freely in your wallet.

          /Magnus F.

            Might also look at the ZZR tire, a newer offering from Avon. It looks very similar to the Toyo R888, and has received many positive comments on BC.

            Roger Kraus is in Castro Valley, just a few miles from you. He will either have or be able to order the CR500, ACB 10, or ZZR from Avon, as well as the Toyo R888, and should be able to mount tires on the delicate MB wheels without damage.

              Randall,

              Are you still using the ford ECU ,maf and injectors?
              Whose cams?
              Which throttle body?

                Emerald ECU, no MAF, bigger Bosch injectors
                Crower cams
                CFM (I think it was this one, but they make two and I had to send photos so I'd gt the right one, and don't recall which one it was: <http://focus.c-f-m.com/cfmbillet65mmthrottlebodyfor00-02zetecexcsvt.aspx>)

                  Note that I run the camber recommeded for bias ply tires such as ACB10 and my slicks.

                  I think it's 1/2 of the typical road radial setting or .75 front and .25 rear.

                  I just don't both to change it back for the street driving I do on radials.

                    If you have an Emerald, or other club racing ECU, you don't really need MAF since you can map off throttle position and RPM just as easily and get quicker response times.

                    The only upside with MAF is that it automatically adjusts for varying loads at idle, such as A/C, electric seats, etc. Not a big deal in a Caterham.

                      Follow up

                      All,

                      Thanks for the great start. Between the responses on here and the PMs from Doug I've been able to get answers to many of my initial questions.
                      I'll try to move this out of the introduction area and into the other sections of the forum.

                      Thanks again,
                      Andy
