[mark_GSi]

did a 16.8 secs @ santa pod on sunday

is this a good time??????

[Dicko]

you need to loose the 17s next time and ull see high 15s

[epo]

did 17 seconds in me gte alls i had was k&n induction kit jan speed exhaust runnin on 15's

[Stuart]

get a magic 4.176 (or 4.18) FD and your laughing ;)

[YellowTurbo]

is a respectable time for 17's

[BC]

this is probably a stupid question but what difference do the size of your wheels make?

[epo]

big wheels = better top speed
smaller wheels = better acceleration
i recon ne way (thats wot i was told)

[Dan]

i agree with the gearbox mod cos i did this last week, the other 2 previous records for site times with 1.6 8v held by cp and mc were also aided by the famous 4.18 mod, as long as you dont mind revving at 4300/4400ish at 80mph in fifth instead of 4000rpm lol

[BC]

cheers for clearing that up for me.

[mark_GSi]

wots this 4.18 mod??

lost me??

[Ben (lurk75)]

replacing the final drive cog in the gearbox to aid with the quicker accelaration, i believe they use it out off a WR F13.

I have no idea about this just what ive picked up.

[elsey197]

i got 17.04 in my gte on sun and all i have is a pipercross induction kit and a scorpion exhaust and 16's!

next time my spare will, sub and shelf are comming out!
:wink:

It is possible to get 4.34 FD, Vauxhall part.

I got 16.2 secs out of a standard GSi lump with 16's and full interior so that time seems a little slow...........

where can this be found................?

[mark_GSi]

i dont think its running right neway, need it setting up, wot the address for velos????

they ne good????????

[Gunzi]

I went on Sunday and that time isn't great but you are running 17" wheels. The thing I noticed is that its was scorthin on Sunday this affected my time - I wasn't as fast as previous attempts. I got 16.29 outta a standard gsi running 15" wheels and full interior. But Sunday was 16.53 and no quicker (I had added a 4-2-1 manifold since last time I went). I was pushing the bugger down the queue with the bonnet up just so it would cool down.

[cornish]

Theres a 4.53 final drive for sale on www.rallyusedparts.co.uk

[Stuart]

damn it its in swansea. shame i dont have ?150 i can dispose of like that lol

[Gunzi]

Would this redue the top speed? the very top I could get was 130 in my 1.6 8v but would this be reduced by this different gearing to increase accelleration?

I'm guessing Vauxhall? LOL :P

Yes it will reduce your top speed. Not sure what it'll reduce it to tho.

[Stuart]

dan was on a 3.94 and went to a 4.17 (or 4.18 cant rember exactly) and i work out that he would loose about 3-5% from top speed

[Philsutton]

i got 16.4 at santa pod im my 1.4 8v, it has a ported polished head, piper cam vernier pulley, an a 4 branch. Still aint bad for a 1.4. Going down santa pod this sunday again.

Not really. Average 1.6's with zorst/filters etc but without head work and cams etc do 16.5/6.
If you had been competing in the Novaload Pod shootout you would have come last out of a field of 12 1.6's. The next slowest time was 16.63 - the fastest was 14.78
