0-60 N/A Diesel

[8v-of-fury]

Its why we all drive diesels isn't it?! lol

[R.O.R-2.0]

This is the only forum I know of that someone would bring economy into a discussion of best shift points for 0-60. Lol. I can honestly say that's a first.

if were talking 0-60 times, there should be no discussion if you arent running a turbo..

the 0-60 time is the exact same on every single n/a out there..... SLOW!

Haha fine then. Open it up to all cars! Turbo or non. List your cars info and time. Fastest idi I've seen on youtube was in the 7-8 second range. What are some of the guys on this forum running?

But I think its still interesting to see what n/a cars are running. I especially want to know mines so I can compare when I finally get my vnt on in a little while. (Just need to make a trip to the junkyard to try and find some cheap charge piping and maybe an intercooler.)

But I always find some kind of baseline for every car I own before I start modding.

Haahaa wanna talk about a short gearbox? Try sootys
its a 91 na jetta,i" think" the trans code is awy maybe?
well whatever it is its short as hell.
i think its the same ratios as a rabbit gti box.
revs? I got alot of em.
try 4000 rpm at 65 indicated on my gps in 5th
i can cruise at 30mph on main street in 5th,and by the time im thru an intersection leaving a light im in 3rd by the time im thru
one day il get off my lazy butt,and hook in my gtech and see what itll do.
id estimate it would haveta be an easy 16 sec 0-60.those close gears keep the hamster wheel goin at full tilt!
i still get over 40mpg too,i dont really check it but when its over 40 and it looks this good,who cares?
Thanks for this theman53!!


Sooty the barhopper.

Yeah. I'm going to clarify that isn't how I always drive: just when I'm pushing for 0-62 times. And this engine seems to pull well right to over 4500, and drops off quickly above 4700rpm. Yes, I know it's a diesel, but it does rev like a push-rod gasser. 
I think the point of this thread was to find out what an N/A would do. It wasn't meant to be impressive times, just interesting for anyone who drives an N/A car.
And ROR, there is a point in revving these engines that high: because you rev to where the torque curve falls off, not where it peaks.  And I know the GC is the worst transmission ever made in the history of the world. It's just what came attached to the engine, and it works fine as long as I don't want to go faster than 130km/h, which is well over any legal limit around here.

Yes.

So you hit the next gear in the torque again.

well, even my old n/a, i wouldnt rev that high unless i was trying to make my passenger giggle..

and my old n/a was FAST.. it would go 100+mph on flat ground, GPS verified..

3200-3500 to keep up with freeway traffic, I can't imagine shifting much lower.

Thinking back to my NA days, I'm pretty sure SOP  was;
 foot to the floor
 clutch in
 shift gear
 clutch out
Never had any problem related to that.

oh yea, for sure.. you dont ever take your foot off the go pedal when you drive an n/a, even when shifting..

[Rising]

Flat foot shifting? Seriously? Won't that like instantly destroy my engine/transmission?

Guess I have a lot to learn about these little diesels. The only flatfoot shifting I've ever heard of is when you have a rev limiter cut spark at a lower rpm (ie your 4500 or wherever your gears usually drop back in) when your clutch is in. Makes some wicked sounds and flames out the exhaust on gassers...

Could something similar be done with our fuel shut off valve? Especially for those with the governor mod who could float valves shifting like that?

Back on topic: more times people!

I love this thread. It makes me feel better about having an under-powered little smoke machine.
Flat foot shifting works if you haven't governor mod'd your pump, and you still have a functioning governor. If you've messed with the max fuel stop or the fuel screw, your governor is probably not going to work right either. I haven't driven it that way on mine, but I'm guessing it'll probably over-rev.

For now, I'll just drive the piss out of it, and if anything breaks, I'll fix or upgrade it.

[745 turbogreasel]

Yeah, the gov  keeps you well below dangerous RPM for the engine, and you still don't make enough torque to hurt anything.
The faster you do it the less speed is lost, and every 0.5MPH matters.

Honestly my old car was much much faster. But there is something about driving this little beast that is so satisfying. Even though my mind knows 15 second 0-60 is miserable, it is so satisfying to see the change the little things add up to a couple seconds of performance change.

Someone has said before: Its more fun to drive a slow car fast then to drive a fast car slow.

That being said I can't wait to add some boost and run it again haha.

745: sounds reasonable ... I'd try it but with my throttle screw being out I know I can rev higher... I wish I had a tach : (

i used to shift it fast enough that it barely came up in RPM..

either that, or it was already on the governor.. lol

and they dont have enough power to worry about burning a clutch disk.. lol.

While shifting quickly might help your 0-60 time, it's he11 for the synchros in your transmission.
