Well, if I could've pulled my head out of my ass for more than one pass, it would've made an 11 second pass. I was simply not mentally ready for 1/4 mile. Kept forgetting about my 3-4 shift because I'm hard wired for 1/8. Seriously pathetic lol, I mean who forgets to shift?! The worst run was when I panicked to shift to 4th and I NLS from 3rd to 2nd!!! Dumbest most noob **** I've ever done. I got lucky, trans and engine are still fine and I went out and made a 12.1 pass afterward. WHEW! Nonetheless, the car did excellent. Was pulling 1.7 60' all day with ease. So close to 11s. BUT, I can now claim to be the fastest stock chassis HHR on the planet, so there's that.
BTW I'm not sure how many transmissions can hold together after being NLS from 3rd to 2nd...but this one sure does

Awesome job on the run and I'm really envious on your 60's that's just awesome. You definitely have the launch way more figured out than I do as I was still laying down 2.05 on slicks. On a fwd stick car there is a lot that goes on, running a 1/4 mile. I was skeptical that you would be able to run out the 1/4 in 3rd and it sounds like you couldn't. I can't believe your motor or trans didn't pop on that shift. Glad you were able to drive it home.
I'm not so sure you would want 3.82 for drag racing unless the car was gutted for weight loss and/or a fast spooling turbo was used. As others have mentioned, the 1-2 shift is not the most ideal ratio change (especially with 3.82 fd) unless you have the power down low to back it up, then it becomes very useful.
As far as 3rd gear pulls, I wouldnt discount the 3.82 just yet unless we're talking 500+tq. I'm hoping I can make that gearing usable for the 450tq cars with a reasonable tq curve but that has yet to be determined or proven. Time will tell.

3.82 would give you the best chance at revving out and finishing in 3rd. That's all I was trying to say. I think the 4.05 sounds like the perfect in between trans.
Was just playing around today and tried going 2nd to 4th (shifted to 3rd first then down without letting clutch out) and at 6,000 when I got to 4th I was at about 3,300, with the 4.45. Wonder what 6,700 would net. I know the ratio isn't great for power, but not shifting 3-4 towards the top end and slowing the car down in the process would be worth trying once. I'm sure it's still faster going through the gears and revving them out especially if you are going to nls.

With the 4.45, a 1-3 shift would be much more effective in that scenario. You know how it feels starting around 40 in 3rd 
NLS with this trans is virtually effortless. This thing NLS so smooth. I shift really f****** fast and the trans accepts it every time unless I fubar the pattern. So the 3-4 shift can't be holding me back much. Maybe I just need to throw the 3.82 gears in for next year with the TQ of the 6758 Zfr and see what it can do. Hmmm

Strapping the front will virtually eliminate weight transfer with a good set of drag bags in the rear. I thought about pioneering a super secret setup for these cars but i doubt its going to happen. Its something ive discussed before but i dont see enough hardcore racers to consider doing this and a one off will be huge cage.
Cough... you need a sheet metal intake and piping from me..... cough cough

It's pointless to try and run out the gears with power dropping at 6300, especially when I shift faster than the speed of light.
Of course skipping gears is not effective for gaining ET

Mr B- what kind of mph are you at, at 7300?
I tried last year on my 3.82 to rev it out even though I knew the hp peaked at about 5900, just to see if I could do it. I ran 1st and 2nd to 7,000 and ran 3rd to 7,250 and started bouncing off the rev limiter 30ft from the lights and the car started slowing down and ran through at 115. There is no way I can rev out in 3rd on the 4.45. I finish in 4th at about 5350rpms shifting out of 3rd at 6,500.

If I go to 1/4 mile again with this turbo, I will try to run it out in 3rd. Hopefully I'm more mentally prepared the next time I take on the 1320.

It's not bouncing anymore since I strapped it, check out the video on the previous page. Slower rebound shocks would be a great addition though. Which would you suggest?

hell if I know I just worry about trap rpm and mph

It will bog in 2nd gear out of the hole because 2nd gear doesn't have enough gear ratio. 1st gear with a 4.45 and turbo is to short. You could do it but you will have to slip the clutch for quite awhile to get/keep the rpms up and it would hurt your times to much. Quaffe 6 speed conversion with 4.45 gears would be perfect. But it's $4300 installed. I think it's got to best ratios on any f35 or the f40.

I'm running 4.05 now. I was running the 4.45 last year but I don't remember what speeds . It really all depends on the tire used. On my 26" radials with 4.45, it felt similar to the 4.05 with 24.5" tire. If any of you drag race with the 4.45, my first choice would be a 26" slicks for best rollout. Makes sense on paper.
I did try a 2nd gear launch on the 445 once. On a 26" tire it didn't work, fell on its face and gave the clutch a hell of a workout. Even on a 24.5 tire, I don't think it would work

Last Friday was the last test and tune of the season at my local track so I couldn't resist going and beating on this trans one last time. Even with the 1.5 month set back in the middle of the season, I made a TON of passes on this trans NLS and all. I'll see if I can find all my slips from this year for a final tally. Looking forward to next year for sure!

I'm pretty sure I'll stick with the 4.05 next year depending on how well it works with a bigger turbo that has more lag. I might take some time off anyway so I can throw some pistons and rods in. Hopefully that doesn't take 6 weeks lol.

Design of the latest modifications is complete. These are VERY important output shaft modifications which will align 3rd gear and replace the crush sleeve with a larger, tighter fitting spacer which must be custom sized per gearbox. I will be completing a 445 lsd build utilizing these parts within a couple weeks. I'll post up some pics so you all can see how big of a difference the rigidity of the output shaft is compared to stock.
