1.3 grasstrack

[smiffy]

im going be building a 1.3 grasstrack car, so far the list off improvements are:

induction kit(cold air feed)
advanced timing
lightend flywheel
fully striped out
4-2-1 exhaust
lowered suspension

my questions to you helpfull pepole are:

1. which gear box will be better for accelration 1.0 or 1.3.?
2. will self drilled brake discs have a noticable amount off weight loss and will be less efficiant or the same.?
3. will removing limiter make a difference in the 1.3.?
4. will a uprated fuel pump make much off a diff and if yeah any recommendations.?
5. any other mods that can be done with out breaking the bank.?

you will probably need to match the g/box to the track you run smiffy (we used to change the diff for each different track on the ovals)
the limiter depends on what cams you have
and a raise in C/R should near the top of your list

 

[smiffy]

the track is your basic oval two straights of same lenght two corners of same bend and speed, the surface is hard to loose dry/wet mud/dirt,
the cams will prob be standard, and how do you raise the C/R (taking thats compression ratio)

 

[frank]

you will probably be holding it in 1 gear then eh (maybe 2) so you need to find out/test which g/box is best suited for the track you run eh (either the post 98 1.0 (4.45:1 iirc) or else the others
and you,ll probably find they,re all running at least 11:1 C/R

yeah useually in my 1.0 i keep it in 2nd, main thing that i think counts on this track is acceleration and handling
