Stoffregen Motorsports Posted September 12, 2014 Report Share Posted September 12, 2014 This probably isn't a good idea, but a couple threads lately in the Engine department have been reminding me of the old days when I actually drove a 510. I know what we were capable of back then and I may share that info, but before I taint the minds of potential contributors, I just have to ask...what's the fastest you've actually gone in a 510? I know we'll probably get a ton of fishing stories, but that's cool. Just DON'T LIE!!! Now mind you, there are plenty of ways one can attain high speeds legally, like the race track for instance, so don't feel the need to include highway names or interstate numbers, etc. We'll just assume this all took place at a sanctioned event.

datzenmike Posted September 12, 2014 Report Share Posted September 12, 2014 Maybe 70 in mid '70s in a Canadian '68 4dr. Quote Link to comment

metalmonkey47 Posted September 12, 2014 Report Share Posted September 12, 2014 Maybe 70 in mid '70s in a Canadian '68 4dr. That's all? Dang Mike, we need to light a fire under your ass! 1 Quote Link to comment
fourfiveten Posted September 12, 2014 Report Share Posted September 12, 2014 100mph gear ratio needs to be different for more I think. 72, L16, turbo. Quote Link to comment
laotsu Posted September 12, 2014 Report Share Posted September 12, 2014 I did 95 two days ago in my 521. and I know the speedo is correct cause we have those "your speed" radar signs", 'round here. I know it can go faster I was just askeert of hurting the new motor. Quote Link to comment
Stoffregen Motorsports Posted September 12, 2014 Author Report Share Posted September 12, 2014 100 mph is totally attainable in a 510, or 521. 1 Quote Link to comment
FiveSeventyZee Posted September 12, 2014 Report Share Posted September 12, 2014 I got mine to do gps indicated 96 mph on a tired L18 in my '71. swapped to KA and it definitely had more in it but I never had the man parts to try after I lost a wheel at 70 mph haha 1 Quote Link to comment
Laecaon Posted September 12, 2014 Report Share Posted September 12, 2014 I hit 87mph with my l16/auto wagon, fully loaded(couldn't see out rearview mirror) 105mph with the a bored out l18 and dogleg, empty with a slight downhill. Quote Link to comment
Stoffregen Motorsports Posted September 12, 2014 Author Report Share Posted September 12, 2014 I hit 100 in my 320 before. 4.88 diff with 6.50 x 14 bias ply tires, OD 5 spd trans behind 100 hp in an A12 running over 5500 RPM. I don't want to do that again. Well I guess I can't since I sold the truck. 1 Quote Link to comment

danfiveten Posted September 12, 2014 Report Share Posted September 12, 2014 130 ish on my lz 2.2 racing a vw red golf when i was 18 and stupid. Made it from la center exit on i5 to van mall exit on 205 in under 10 mins. Really surprised we did not get pulled over, my buddy pj in the passenger seat was digging his fingers into my dash and i kept knocking his hands off it screaming DONT HURT MY DASH! lol. Me and him will never forget that day. Fastest ive been in art was 95 3 Quote Link to comment
paradime Posted September 12, 2014 Report Share Posted September 12, 2014 I hit 110 in about 7 seconds in my 510 and I have video of that fish. OK it's an SR20 swap with a GT3071R. Not sure if that disqualifies me. Interesting side note for 510 fans. I just learned the "Woolworth" five&dime store got it's name from what they called the 5-10 split in bowling back in the day. I love cool shit like that. 6 Quote Link to comment
r0p0doe Posted September 12, 2014 Report Share Posted September 12, 2014 108 in my current dime with just me in the car and gps verified. Nice to see danfiveten got up to numbers I'd like to achive with my lz2.2 after some more tuning and mods... Quote Link to comment
housew Posted September 12, 2014 Report Share Posted September 12, 2014 good thread. 80 so far, but i've only driven the car about 10x. I'm sure it will creep up there. It more trusting the chassis than having enough power. se20det and a 5 speed should get me going pretty good. I know 80 isn't a problem at all. Quote Link to comment
freekwonder Posted September 12, 2014 Report Share Posted September 12, 2014 High 70s I believe, would have to check the speedo. Luckily the speedhut GPS gauges records highest speed so I can verify. Haven't really gone much faster than that since I only hit those speeds on the highway and my son is usually with me. Not quite sure I trust her much higher speeds if he is in the car with me. If I'm alone it's one thing, but not with him. Quote Link to comment

If I'm alone it's one thing, but not with him. I get it. 510's can be squirrely at speed, unless it's stifly sprung, which most street cars are not. Quote Link to comment
DISLEXICDIME Posted September 12, 2014 Report Share Posted September 12, 2014 135 in my old 510 and it was scary as shit. It gets all quite in the car and around 120 125 you can feel the ass end getting light and starting to slide around . Very sketchy 3 Quote Link to comment
danfiveten Posted September 12, 2014 Report Share Posted September 12, 2014 Yah it feels like u want to fly. Quote Link to comment
510T Posted September 12, 2014 Report Share Posted September 12, 2014 135ish a couple times. The sr20det wants to keep going but I usually don't... The car feels great at speed though, lots of caster and rear toe in helps ;) 2 Quote Link to comment
datzenmike Posted September 12, 2014 Report Share Posted September 12, 2014 That's all? Dang Mike, we need to light a fire under your ass! I'm totally guessing I never looked and didn'r regularily drive it fast. My '74 L18 auto 710 up a slight grade just over 90. Do not tell me autos are slower than standards. About '95 in my '76 710 goon. Maybe 70 in my 620. Other cars.... 155 in my '70 Dart or 6,250 RPMs in 4th Above that in an '09 Corvette* Way above the Corvette in a '13 Shelby GT 500 Super Snake equipped Mustang* * the Corvette was set to KPH and read 200 topped out. Hell I hit that on the on ramp alone and went through three more gears after that. When the owner thought to switch to Mph I had already slowed back down enough to read and comment on it. Fifth @ 6k is about 150 acording to on line specs. Held it in 6th for less than 10 seconds. Scary. * the Shelby was beyond mach one. I was too scared to take my eyes off the road. It was down just below 130 when I did look. Maybe 170? surely above 160. Cracking the whip on 850 horses? who cares Quote Link to comment
Just Joel Posted September 12, 2014 Report Share Posted September 12, 2014 Somewhere near 100 mph last spring trying to catch a swapped dime on the way to Canby. Got sceeerd and backed off ;) Quote Link to comment
Stoffregen Motorsports Posted September 12, 2014 Author Report Share Posted September 12, 2014 My brother and I made it from Walnut Creek to Sears Point one Sunday morning in 28 minutes. It's just over 40 miles and there are two towns and a toll bridge to get through. I was driving a Porsche 911 and he was in a Corvette. We both hit about 150 at one point. 3 Quote Link to comment
paradime Posted September 13, 2014 Report Share Posted September 13, 2014 680, Martinez Bridge, 780, 80, 37, 121. Yah, I been there. You have a distorted sense of "fast" sitting on a lounge chair with the windows rolled up and the AC on. Do 160 mph on a motorcycle and you feel every damn bit of it. Visited that many times on my GSXR 1100 Highway 94 East of San Diego. Back to 510s 4 Quote Link to comment
datzenmike Posted September 13, 2014 Report Share Posted September 13, 2014 Well being on a bike is distorted too. 30 on a bike feels faster than 50 in a car. The 510 is a brick with wheels. Mine was about 8 years old at the time.. it rattled and shook and you sure knew you were gong 70. Quote Link to comment
