d15b7 Posted November 24, 2020 Share Posted November 24, 2020 here's the final race of the weekend for me (sunday morning). the track was not good (there had been too many engine explosions and oil spills to count on fri and sat); T1/T2 was bad. the T6 through T9 was very slick. T10 wasn't good. the only good sections really were T3 and T4 and T5 was OK. I was running a set of very old Toyo R888s (I was planning on finally buying new tires this year but then Covid happened). the major change to my Seven was to the crossflow motor; over last winter I installed a used dry sump system replacing the wet sump and accusump. also I spent hours and hours rejetting with the help of a newly installed AEM A/F gauge and had it dialed in pretty well (it had been running extremely rich below 5000 rpm and was moderately rich from 5000-7000). the result was that even on a slow track, I had a fantastic personal best of 1:23.8, backed up by 1:23.9 and 1:24.0 during that race. The leader was in a Elva MK7 Twin Cam sports racer and was consistently running a sec a lap faster than I was (he was uncatchable). He was over 2 secs off his normal best laptimes (the track was really that bad). That 240Z that came up in the start of the race was VERY strong and seemed to handle amazing in the straights!!

searya Posted November 26, 2020 Share Posted November 26, 2020 Looks like a great track and a great run. You definitely used every inch of the track they gave you thru those turns. Great job! Link to comment Share on other sites More sharing options...
Croc Posted November 26, 2020 Share Posted November 26, 2020 Great video Todd! One question - what's your thinking for the narrow entry into Turn 5? Is it that you maximized the high speed turn 4 and there is no incremental speed/time advantage to coming all the way back right ahead of the entry into Turn 5 as you just travel too far?

sf4018 Posted November 26, 2020 Share Posted November 26, 2020 That was fun to watch, thanks for sharing! 1:23 in those track conditions shows how precise your lines and car control were. It's a bit of an empty win for the Elva with that straight line speed advantage, I'm guessing you and the Datsun had a much more fun. Link to comment Share on other sites More sharing options...
d15b7 Posted November 26, 2020 Author Share Posted November 26, 2020 hey guys! Happy Thanksgiving! thanks for the kind words! Croc -- I prefer to maximize T4 (in perfect track conditions on fresh tires Avons I don't even lift there; last weekend with the track so oily/greasy and with nearly 8 yr old Toyo R888s I had to lift at the turnin point and then roll back onto it) and if you go through T4 like that you need to enter T5 much more on the inside. it's a good tradeoff as the loss into 5 is much less than the total gain in 4. if i'm really hauling through 4 like that there isn't any way to get back to the right for 5 and still get the braking done also. i'm 99% sure that if the track was perfect no oil/kitty litter and on fresh Avons it would have been 1:22.x no problem. of course the Elva would have been in the 1:20.x most likely too haha. he's in FM and i'm in EPv class so I 'shouldn't' beat him, but that doesn't mean I don't want to win overall (; Link to comment Share on other sites More sharing options...
d15b7 Posted November 26, 2020 Author Share Posted November 26, 2020 oh and Croc? your CSL racecar would have fit in nicely in Group 3 with me! these guys were all running Group 3: Link to comment Share on other sites More sharing options...
Kitcat Posted November 26, 2020 Share Posted November 26, 2020 Very exciting to watch! Although, I should add that your competition in the 240Z consistently displayed superior "straight line driving skills." Link to comment Share on other sites More sharing options...

Although, I should add that your competition in the 240Z consistently displayed superior "straight line driving skills." haha ya that guy really knew how to wheel a car down the straightaway!!! I asked around and it was most likely a 2.8 (not a 2.4) and when they are built with the right parts 300 hp at the flywheel isn't too difficult to have. and a 2000-2100 lb 240z is very doable. it could move that's for sure!

We spent a lot of time swapping ideas as he was ahead of me in the restoration process and were were both using Korman Autoworks to do our engines. Really knowledgeable guy.
