Depends on how hard you are willing to hit it at the starting line. Might [ likely to ? ] need a trailer to get it home.

I disagree. Stock weight, 180hp, stock gearing, street tires. 9-10s 1/8 mile.

I ran 10.40’s with a 2180lb. Superbeetle with a 1776. High 7’s-low 8’s would be a perfect world with slicks, but I would think you should be able to get below 9. I ran fairly close to a 95 ZR1 Vette at some 1/8 mile fun runs with a lighter 67 Beetle and a 2276 making probably a little less hp. The 90’s ZR1’s ran mid 8’s if I remember correctly.

Like grandma pulling out of the grocery store parking lot...

Hopefully your SSC trans is an AT with a 3.78 1st/15 tooth diff outdrive. If it’s an AH with a 3.80 1st/17 tooth outdrive, it’s not if, but when it’s going to break. If you have done all you can do to prevent wheel hop, you could probably get a AT trans to live a little while, but the spider gears/CV joints will be the weak links.

My guess would be 9.30's with street tires and maybe 8.80's with slicks

You won’t get everything out of the engine, unless you get everything out of the transaxle. “Running it till it breaks” is only going to put you out $150, but everyone in the staging lanes at the track waiting for cleanup won’t be too happy. You need a sub 1.70 60ft. times to start seeing quicker times, and that’s not likely going to happen with a stock trans.

as long as you willing to throw away $150, how about selling me that trans as a core so I can scavenge the 3:88 and put it into a more stout trans thats set up for the track Laughing

Then i would have to buy another $150 trans. Im not trying to grenade it just saying if it does its not going to be a devastating loss like say a $2000 trans would be. But i will keep you in mind if and when I can afford a better trans.

I doubt your gonna break your stock trans if your on street tires with that combo. And if you do, i doubt it will be your ring and pinion. If you pre-load the trans alittle, let the clutch out 3k and shift each gear normal. If something does break, then its a great time for a upgrade anyhow.
Because of the gearing, im with Hotstreet and say 9 + seconds.

My first timed runs a few months ago with less heads, less total lift, I was able to get 8.2@82 in the 1/8, 13.0@102 in the 1/4, but my gearing is tighter. Gearing really makes the difference. Mine has only 160hp and 205/70/15 street tires.
Those runs from a few months ago:

I ran 8.7 at 78mph with 185hp to the wheels. 2000lb car with drag radials. Leaving the line at 5400rpm.(should of been 6k but no chip)bogged a tiny bit.

Car wasn’t at full throttle due to driver/builder error. But every calculator I try puts my car in the low 8’s since I know my exact weight and hp.

2783cc with all the drag stuff in it.

That sounds weired Vikings.
165 hp 2275 (with a massive torque though) Stock ratio 4,125, Bf Goodrich Drag radials, 1775 lbs incl. driver. (1957 oval) Runs consistent high 8´s on an unprepped track.
Full weight ´64, 2332, 210 hp, Built trans w. 3,88 R/P. 3,78/2,06/1,32/0,93. Dot 6" street slicks. 7,95 - 8,00 on a prepped track, 8,20´s on an unprepped track

With the OP. I agree, low 9´s is the most likely.

A super diff, and side cover at minimum. You could get away with a VW mainshaft if you weren’t at the track a lot. You could get a Weddle mainshaft, and one of their 091 internal super diffs with 100mm CV joints for something that would last for a few hundred passes in an 8/12 second Beetle.

I agree. The #’s don’t lie. My engine on engine Dyno made 210, then upped compression to 10.8 from 9.6 and did a Ton of porting to already big 910 heads. Chassis Dyno was just done Wednesday at westech and 185 at the wheels. The car never saw 4th in the 1/8. (Belt on through Muffler

https://robrobinette.com/et.htm

Car weighs 2215 with me in it. Engine should pull to 8k. It does not. 185 and it stops pulling at 6k. Once I replace 20 year old valve springs it should pull like a Fk 89/91 likes.

091 bus trans. TBD diff 930 cv’s 4:13 r/p
All Weddle gears.
3.11x1.93x1.22x.82. This is not a 1/4 mile set up by any means. It is a fun street car.
