    I have heard a LOT of mixed stories around that supercharger package over the years but to make sure it is not just like UFOs/intelligent blondes/honest politicians/etc. (i.e. you hear about them but they don't exist in my real life) it would be interesting to hear directly on this forum from a happy customer.

So a 485 is a healthy hp car but less than your Ultralite's 243hp which you stated was a condition. It is an SV wide body. Given your hp focus, I don't think you would be happy unless you have more.

    You make me sound like a one-trick pony, Croc. Actually, handling is Number One, and newer Bruntons (pushrod suspension) and newer Birkins/Caterhams are well-endowed in that area, plus have the classic proportions that I prefer. Now, as I choose between all the contenders, I will look for the power edge to help me make my call. With Sevens, it is my experience that HP helps off the line, yes, but also at the end of long straights, where the brick-like aero qualities of Sevens do their worst. Sevens usually catch up in the braking zone, but if we can make 150 mph or more down the straight, and get to speed quickly (instead of the typical plant-your-throttle, light-a-cigar and grow-a-beard response), it is easier to pass and to shake those big-horsepower thunderbutts menacing us from behind.

    I appreciate your analysis of the 480 SV. It likely would be very equivalent to my former WCM S2K in performance, but at least my wife could fit into the passenger seat!

    I, too, am suspicious of the overall performance and longevity of the Rotex supercharger. In my discussions with the progenitor of the WCM marque, he told me he did not offer a supercharger because of packaging issues and no place to position an intercooler. Without an intercooler, heat saturation quickly robs the motor of most power gains. That is the problem with the Lotus Elise SC - no intercooler, so the supercharger is not much help on the track - useful mostly for passing situations or off-the-line.

    I am considering V8 Stalkers, either Classic or Classic XL. I would miss the high-rpm motor that's come with all of my former Sevens. In lieu of that, I'd pick up loads more grunt down low - those LS motors are like diesels down there! I would also sense, at all times, the presence of an additional 400 to 500 pounds weight. It would not be quite the flea-flick driving experience of a lightweight Seven - more like an improved version of my Alfa 4C. I'm also considering a sequential trans, like a Sadev or Quaife, and I don't believe sequential or DCT is available on a Stalker. Since GM pushed Tremec to develop a DCT for the mid-engined Corvette, however, this engineering may flow out to hot-rodders and boutique car builders like Scott Minehart of Brunton. I am looking into that presently. I would consider a Caterham 620R if 1) they didn't sticker for used-Ferrari prices and 2) there was actually room for feet in the footwell.

    Nonsense - ponies shit and gallop and kick you when you least expect! More than one trick in that!

    Yes - exactly. No Caterham or Birkin I know of reaches 150mph on a track though. Best I saw was when I drove the 620R at 146mph at both Estoril and Hungaroring circuits although I suspect I did it late in the day at Portimao but I was shitting myself as I came off the cliff into the high speed understeer drop onto the main straight and not paying attention to the speedo or rev counter. They all have big ass F1 long straights. In theory my CSR does 155mph at vMax but I am yet to take it to Bonneville to see if I can find it after a 5 mile run up.

    Some user on this forum did a Birkin one - I think it was TheGoat or Goat. A search here might surface the name for you to PM and inquire. I vaguely recall an intercooler being used but cannot recall where installed.

    On a positive note, the Caterham 620R installation has been quite reliable on track based on UK owners I know who have done 6000 track only miles.

    Yes you move from a fully loaded 1250-1300lbs to a 1750lbs Stalker. While not totally cruise ship like in handling, a Stalker does have more weight/inertia in being thrown around. A Caterham is quicker in the corners but the stalker walks...errr....runs away out of a corner. Torque is your friend there. Not much between them under brakes though. It depends on your local circuit. A tight circuit like you get in the UK suits a Caterham well. A big open USA circuit suits a Corvette/Mustang/Heifer/etc which only go fast in a straight line then wobble around corners.

    The Sadev tops out around 350-400hp from memory. But there are sequential transmission options for the LS engine

    Option 1
    https://shop.quaife.co.uk/chevrolet-...ential-gearbox

    This is T5 sized so should fit a Stalker gearbox tunnel.

    Option 2
    https://www.lgmotorsports.com/corvet...nsmission.html

    Both can be combined with paddleshifters.

    Option 3
    Put a hydramatic in it and just pretend it is sequential.


    Anything can be done with money and a shit eating grin.

    The 620R is RHD only. Cannot be LHD as the supercharger packaging gets in the way. You can order a 620R SV with the wider cockpit and bigger footwell. I had no problems driving that version in Spain and Portugal. I drove the S3 version in Hungary but did not notice the footwell issue as I never used the clutch after getting rolling and just left foot braked to avoid confusion.

    As a long time WCM owner that just recently picked up a V8 Stalker I can say that the power more than makes up for the weight. At ~1600 lbs it still feels significantly lighter than my 2000 lb Elise and is much faster in every gear. I haven't taken the Stalker to the track yet but if road performance is any indication it will destroy the lap times I set in both the Elise and the WCM. Personally I think the choice of tire width and compound makes a bigger difference to the handling of a Seven than 100-200 pounds of weight.

    rnr, You ended up with one very beautiful Storker! I don't road race but have some limited experience with autocrossing Stalkers. My first Stalker was an LT1 equipped prototype M-Spec that I purchased from Scott Minehart of Brunton Auto. I had racing slicks for that car and that was my first autocross car. Then purchased a NA V6 Classic Stalker and then my third Stalker was a supercharged L32 that I had racing slicks/wheels to do autocross and the thing really performed. My latest Storker is a XL with the LS3/480 and I absolutely LOVE the torque and horsepower that it provides for my 1860 pound car. Your chassis being #159, you have one of the very last Classic Stalkers that was ever produced. The upgrades you have with the new Wilwoods and other mods to your LS3-engined car make your car a veritable hot rod. Shane knows all about them because he can run a track or fly through the air with the greatest of ease

    Glen Minehart, Scott's father can suggest all kinds of wheels/tires for track use. They have a Brunton AXR along with their son Jason and have tried all kinds of tires and compounds for the best performance. In fact, most of the family will be out in Lincoln, Nebraska this coming week running at the SCCA National Solo Championships.

    To save Croc the bother, I will add that wheel diameter can affect the delicate handling balance of a Caterham, with 13" apparently being optimal (tho greatly limiting available tire choice).

    I agree it is odd to claim 1600 lbs is heavy. Most car forum's discussions on weight involve getting below 3,000lbs! For them, 1,600lbs would be unimaginable.

    Tom Carlin replaced the former Birkin dealer, mentioned above. I think Tom has built some turbo Birkins with hp in the mid 300's? AFAIK, they weigh in around 1,350 lbs and have a fully independent front and rear suspension, unlike the standard Cat SV.

    rnr, I was talking with Glen Minehart this afternoon discussing the impending hurricane that is putting Florida in the crosshairs.

    Glen recommended that your car would do best with 13" wheels front and back with the front tires being about 9" wide and 20-22" in diameter. For the rears, he suggested 13" wheels that are 10" wide with the diameter no greater than 22" lest the tires hit the fenders. He suggested considering altering the ride height if necessary. He mentioned Avons or Hoosiers work well with the Stalkers and John Berget is a great source for gently used race tires. You can see John's website at:

    The difference between 15 inch wheels and 13 inch wheels is extraordinary when compared back to back on track. I use 15 for road for ground clearance and the 13s just are amazing for pick up on track. Happy to demonstrate to disbelievers.
