what gear should this be done in
i thought it was
5 speed gearboxes in 3rd
6 speeds in 4th
answers and reasons why please

budgie

 

It should be the gear with nearest to 1:1 ratio, which regardless off 5 speed and 6 speed is normally 4th gear.

 

thanks nick
anyone else

budgie

 

anyone

 

Just out of interest, why do you ask?

 

my car was dyno'ed yesterday
and i was suprised to find out after
that it was done in 3rd
other dyno days ive been to have been done in 4th
just wanted to know how this could effect my results
mine is a 6 speed

budgie

 

weird you should say that peter. I had mine done yesterday and also in third. I thought the five speeds should be done in 4th and the 6 speeds in 5th to get the best 1:1 ratio

 

Both times my STi has been on the rollers at Power Engineering, the run has been in 5th If in too low a gear, it may not be loaded enough to make full boost? Would 6th possibly overspeed the rollers? My SECS told me that max. boost was 19psi although I'd seen over 21psi on the road. Max. speed was 143mph

thanks for the replys guys
but we seem to be no nearer a definate answer
i know the reason is due to ratios of 1:1
but which gear is this?

 

what did it make Budgie

 

thats the point arron
427/420
not very impressed

budgie

 

that doesn't sound right mate, jgm is on here somewhere i've just been talking to him he'll know what gear it should be

 

send him over here m8
would like another opinion
was expecting over 460

 

Had my RA on the rollers 2 weeks ago and the car was run in 3rd gear and it didnt make full boost. The only reason i can think it didnt make full boost is because of low the ratios of RA box,it wasnt loaded enough..basically it should of been run in 4th.

 

i thought it was down to gear ratios
if you look at the spec pages
06 sti in 4th is 1.1 ish
06 wrx in 3rd is 0.97 ish
my96 ra in 5th is 0.96 ish
this to me is the gear they should be run in

I had my scooby r/r'd at triton motorsport and it was done in 3rd they said it was because that is the power gear but i do make more boost in 4th 1.1 bar on the road due to the chip i have fitted but only made 0.94 in 3rd on the rollers.

Dyno Dynamics RR - Cars are run in 3rd gear.

 

02 wrx done in third gear, made ok figures too.

 

will depends on the RR rather than the car, the figures are only accertained by calculation, which can be different from RR to RR (as in make), due to how they are manufactured.

as said dyno dynamics are done in 3rd gear on most scoobs iirc
