Tuning / performance update

Gents since we cant get the ratios, thought some quick testing to at least provide data for us on current gearing.

Below is based on displayed speed (speedo, so errors there), testing redline in lower gears which seems to be at 7000 and some calibration at lower revs for higher gears @ either 3500 rpm or 2000-2500 in case of 5th and 6th. I think 6th is slightly under 50klm/hr per 1000rpm, but its very close. I am least confident about the max speed and klm/hr/1000rpm for 2nd gear, but its pretty close.

Max speed in the lower gears was a little higher than I expected, as I had previously assumed a bit over 6500 was the effective redline.

Gear Estimated klm/hr
/1000rpm Max Speed @ 7000rpm* Comments
1st 7.4 52
2nd 13.3 93
3rd 21.4 150
4th 30.9 216 may not redline in 4th, but go close
5th 40 280 max speed of 220 would be at 5,500rpm
6th 50 350 max speed of 220 would be at 4,400rpm

c'mon Sharkie - how's about those acceleration figures?

Need a dry weekend 1st ..... when I have time it rains and when I don't its dry ...

I was initially leaning towards just the H&R springs as i would still like to take the tig on some dirt tracks.

If you want to go on a dirt track, even just a decent dirt road, stay away from the springs ..... it drives like a GTI with the springs and any imperfection on the road is noticable.

It would only be one or two dirt tracks a year and the rest would all be normal road driving with a track day or two.

Probably still going with the springs as the dirt tracks are pretty much unsealed roads which my 20yo corolla can make it down.

20 year old Corollas could finish the Dakar

Hey John have you had that APR DP fitted yet?

[Sharkie]

Going in this morning .......

Expect to have it back in 2-3 days .....

Oops meant Johan Let us know your thoughts

[Sharkie]

Prototype APR downpipe and high flow cat fitted ....

Definately more power, but some testing still to follow, so will keep you posted ....

Any difference in exhaust note / spool up noise?

Hey sharkie, sorry to get off the topic a little...but re the springs you have fitted: How much lower has this made your tig? has it stiffened up the ride on hard corners?? no bodyroll?
