whats the 0-60 book figure for the c20ne in a mk3 astra?

i did 8.5 0-63, that any good?

 

[Gaz]

the book 0-60 time on a mk3 sri fitted with the C20NE is 9.4 and top speed 120

 

[Joekont]

0-60?? I'd say next thursday probably

 

[Gaz]

lmao the funny thing the mk3 cav fitted with the same engine's book 0-60 time is 8.9 .. or as joeknot said it could be next thursday lmao

That time is for the 20SEH sri.

 

[Gaz]

no its not mate, the SEH sri fitted with the close ratio F16 IIRC has a longer 0-60 time as you have to use 3rd to get a true 60 mph. correct me if i'm wrong

 

[tomstickland]

Well seeing that the 0-60 for the Sri 130 engine in a MK2 is 8.5s, then the 15BHP lower engine in the heavier MK3 must be in the 9s. Though as you say, gearing could make the 0-60 better but not the overall acceleration better.

 

[adamSRi]

i got video evidence lmao

one thing i have noticed is that they do pull quite quick off mark etc. read somewhere they pull better lowend than the 16v ?

 

[tomstickland]

Nah you're tripping now.
Calibrate your speed by timing yourself against motorway markers.

 

[adamSRi]

i imagine its around the 9 mark if timed properly.

what 1/4 mile times/ 0-60 u get tom?

 

[tomstickland]

Still, it suggests that it's going pretty well.
My times go something like this:
20SER with Exhaust and air filter 16.2s
20SER with B+ head [email protected]
20SER with B+ head, lower final drive and weight loss: [email protected]
0-60 with same spec 7.3s

Currently its a bit lighter and making a tad more power (throttle sensor set up improved) so it should do 15s dead.
My acceleration calculator says that for me to make a 15.2s 1/4 mile then I should be capable of a 6.9s 0-60. So somewhere around 7s is possible. Bear in mind that I have to do 2 gear changes to get there.

 

[adamSRi]

20ser?
is that same as seh?

sounds impressive, phil said yours is rapid.

do the seh/ser share same gearbox as ne? f16 cr?
coz i only needed to change from 1st to 2nd to hit 60.

 

[tomstickland]

F16CR has same ratios as F20 which means they can make 60 indicated in 2nd but in reality they can't quite make 60 in 2nd, so you add another 0.4s to get to 3rd gear.

SER is same as SEH. Sri 130 engine.
I have F16 CR. But I had different final drive fitted. Went from 3.55 to 3.9. Which means I have to change gear at lower speeds and can drive round town in 5th gear. Ish. Steady 80 on motorway went from 3800rpm to 4200rpm. They're low geared as standard really.

 

[adamSRi]

ah right, cool.

that chip you tried out, did it not make any noticeable difference?
i also spoke to nova16v about it.

 

[dazcox]

Thats good going for the old 8valver for the 1/4 mile times. My best time with the old mk2 130 was a 15.7 with the seats missing and a timed 8.2 to 60
