    For me personally a lot depends on the intended use. Generally, these are my criteria for cycling tires. Daily Driver used for routine local errands: Black Round Tread remains Hold air High performance street car: four above plus the 6-year life. Race car: 6 heat cycles.

    Congratulations Craig! Well deserved

    Croc - Make sure you use a billet or forged crank in the 2.5L Duratec

    I just got up to speed. Your new car sounds awesome Croc! One thing, and I'm speaking from experience here, make sure you use a forged or billet crank! You'll have to have it custom made. That's basically the same engine I had in my Cat when we blew it up last year but engine builder figured a cast 2.5L crank from a Ford Ranger pickup would be ok because it's a street car. - NOT! How was the event? I need posts and pics

    Oh Ohh! What did Croc get? I think we're squeezing all we can out of this NA Cosworth Duratec

    I still don't have my engine back from my builder in CA :toetap05: So I'm not going to make this one. Have fun and stay safe! Best to all, John

    It's touch and go if my engine will be ready, but I optimistically signed up :driving:

    The thought has crossed my mind...

    Wish I was there. My engine's still in CA.

    Hi Croc - I'm not really sure what the HP will be, we're breaking new ground here. For a guess, it's almost the same displacement as the 2.5 which made 200 lb-ft of torque at 7,200 and 274 hp. If we can make maybe 180 lb-ft but about 1,000 rpm higher that could get us over 280 HP. We'll see soon. I'll keep you posted.

    I kind of forgot the Cosworth 2.3 Duratec revved to 8,800. That's Formula 1 and Winston Cup piston speeds. (27.5 meters per second avg, 43.3 max). The short stroke engine equivalent would be close to 9,100 but I don't think I'll push it that hard. We'll see what the torque and HP curves look like.

    Croc, Just go faster and catch 6th going under the bridge
  13. John B
    Kitcat: Probably 8,800-8,900 rpm to keep piston speeds the same as the 2.3 Cosworth Duratec.

    I'm in for October! I'm still working on the new engine as our crank failed spectacularly last year. Rather than the high torque, lower rpm stroker engine we had last year we're going oversquare and high rpm this time, which is more up my alley. It'll be a 2.42L Cosworth/Duratec built by Hasselgren but we're using a 2.5L block further bored and a short stroke billet crank (shorter than the 2.3 Cosworth) so the engine should be a screamer. I'm looking forward to dyno results and testing.

    I also could not see below #81, but the list better include a Lamborghini Miura, Mclaren F1, and an Alfa T-33 Stradale...

    I'm in!! My engine is out in California being rebuilt at the moment. It turns out it did not have a forged crank. Now it's getting a billet crank and we'll try again! We'll get this thing sorted... Best, John B

    RIP Jesse, Never lift

    Simon's in for Sunday. I may just do Sunday as well, I'll see how it goes.
  19. John B
    Alright! I'm in for Sunday 7/28 and Monday 7/29 at Lightning. Are any other 7's going? Simon? Seb? Croc? KitKat?
  20. John B
    Well, that certainly looks a lot swoopier! Can't wait to try it at the track.
  21. John B
    Those are great pics, and nice commentary as well. What a wonderful weekend that was! In fairness, I think that was my son Connor doing a little “Stig” work chasing Simon and Seb.

    Although it's not a 7, it's certainly worth mentioning this BAC Mono on BaT. https://bringatrailer.com/listing/2015-bac-mono-2/

    Nice Lotus Super 7 S2 on ebay in NJ not too far from me. Let me know if anyone wants me to check it out for them. https://www.ebay.com/itm/1966-Lotus-Super-Seven-S2/233282145671?hash=item3650b30d87:g:foUAAOSwepNdI24s

    Hi Kitcat, For what it's worth, my engine builder Paul Hasselgren tells us to run Mobil 1 15w-50 in both our Atlantic and Caterham Duratec's. We have a dry sump and catch tank. Best, John

    Seb - Mercedes just announced the most powerful 4 cylinder ever in a street car. 2 Liter turbo, makes 416 hp! I wonder... https://www.motor1.com/news/354213/mercedes-more-powerful-four-cylinder/
