    Lexan windshield for Gen 5

    Does anyone make one? I'm guessing not or I'm sure I would have seen it by now.
    For the first time in the 4 years I've been doing Time Trials with NasaProRacing.com I lost this weekend. To a brand new 2400 lb Porsche Cup Car. I was not amused. LOL. Need to keep losing weight.
    For those that know my car it's pretty light already, maybe the lightest Viper in the world?? It's about 2930 lbs now. I lost by .4 seconds a very large margin, if the car was closer to 2800 I would have covered that. The windshield is thin, but this could still save 20 lbs and it's high up weight too.
    Doug Shelby is making me a foam core splitter extension that will save about 8 lbs or so, right off the nose too.

    Drive faster



    On a serious note, I dont see a Lexan windshield being a game changer. Is a lighter (smaller) wheel/brake set up possible? Do you have lightened driveshaft or axles already? Lose the dashboard?

    AZ might as well move to a faster class like formula or the prototypes, not sure how nasa names it. But the fastest scca cars are the stohr wf1, 800lbs racing machine and your choice of what ever 1000cc motor. I've even seen one with an s2000 engine. They are fucking awesome.
    The clock around the same times as the GTLM class (ford gt, c7r, viper gtsr). But that's with a 1000cc motorcycle motor.

    Perry's Speedglass used to be pretty good but not sure if they're still around.
    You're rapidly becoming the biggest asshat on the forum and that covers a lot of ground. Congrats. -ViperJon

    My friend rebuilt his Gen5 here in Kuwait after an accident at the track. He couldn't source a Gen5 windshield. ended up installing a Gen3/4 windshield, fit/shape is the same. The difference is the Gen5 blacked out area for the rear view mirror, and the Gen3/4 radio antenna pickup "button" point buried in the butyl when adding it to a Gen5. ACR-X had Lexan windshields. Tom Francis is a good POC.

    I can't. LOL. I'm at 803whp now. I'd have to add turbos and that's opening up another whole can of worms... I'm in unlimited class already.

    It's a small track I'm very fast at, can't possibly go any faster unless the car was lighter. I would have beat him but I didn't have on new tires, he did, that's over 1 second right there. This is a very rich guy with full Porsche crew with giant semi's, stacks of tires etc. My fault, my tire strategy for the weekend sucked. I brought new tires but used them on my TT1 ACR to try and get the TT1 record, missed it by 1/10th because of traffic, then lost in TTU running used tires. I tried to get greedy and it cost me my TTU record!

    Yeah I'm unlimited already. I beat most prototypes, V8 Radicals etc, all but the fastest like the Ginetta's.

    I believe Randy Pobst was 1 sec faster around Laguna Seca in the ACR vs Porsche GT3 Cup of the time. Which is nuts in a car without a cage.
    Want a mod that makes your car faster? Fix the nut behind the wheel!

    I don't know you personally, but enjoy your posts. How much do you weigh? Maybe 20 lbs could be shaved off a lot easier than you think...

    yeah we can all become better driver's, but I'll never do coaching or data. I tried once, that latest about 20 minutes. LOL. Was too much like work and took the fun out of it. The fun for me in this is modifying the car to make it faster

    Put it this way, Cup Cars can run 2.10 at COTA. The fastest a stock ACR has ever gone there is me, a 2.21. A few heads/cam cars have gone 2.19 ish. A pro driver with my race car might do a 2.14 there. Cup cars are cup cars for a reason, it's the best Porsche can do, unlimited funds for engineering. It won't happen again, I'll just make sure to bring new tires. Having a brand new Cup Car in your class= Your tire budget for the year just skyrocketed. LOL

    AZ there is no way, that once you learn COTA(I believe you have only been there once and only did a couple of sessions iirc) that you would not be a 2:12/3 or thereabouts in your 9.0L. FFS a 675Lt Mclaren can do a 2:16 and so can a 720S. Its a high power circuit and you will most certainly use the high power and aero of your car to an advantage At Spa for reference, which is a slightly longer circuit that COTA_about 0.9 miles longer- and equally high power, I should be able to do a 2:27-2:28 there in due course in my 9.0(and my car, weighs a couple of hundred pounds more than yours and has less horsepower). Compare this to a qualifying lap for a series lap for the 991 Cup of about 2:23-. To put this into perspective a 675LT can do a high 2:35 at Spa and a 720s a 2:34. So there is no way you are 11 seconds slower than a Cup Car at COTA buddy! Just need to learn the course more that's all...

    Some time ago I looked at Gorilla Glass by Corning and they had aftermarket applications for Corvettes (11 lb savings over the stock windshield). Not sure if they cover Vipers, but might be worth your while to contact them.

    Cheers.

    At 3200 lbs with driver, it would take a LOT more power than I have to run a 2.12 at COTA in a high drag car. Remember half this track is the two straights. Hence Dodge not even attempting a record there in the ACR. This car just won Global Time Attack there, https://www.youtube.com/watch?v=kRQ2GSj65U8 and it's 1200whp, full engineered race car etc and managed a 2.07. But with a pro level driver etc. I know COTA times extremely well. Last year a 700whp paddle shifted monster vette won TTU with a 2.16. I do know cota, i wont get any faster there. Like I said my 2.21 time is the fastest stock ACR time I've know of. Remember this is Nasa official timing which runs the gators in (2-3 seconds) and allows no cheating, the flag workers will DQ you for four over the line anywhere on the track etc. I've heard of a heads/cam car that ran 2.18, but without the gators in. When I go to a new track my fastest lap will be in the 2nd session then i NEVER get any faster. EVER. lol. Yes because I don't look at data etc, I'm stubborn.
