alright.

ive had a TIM vac guage in for a while and its never worked properly always reads poor or fair and thats bout it. got another one the other day, and it still dont work properly.

any ideas?

im running a 998, that has been tuned by bill richards that works fine. changed all the pipes for it and it still aint working - any ideas?

thanks

i found that often a 998 doesnt have enuf vacuum to get the gauge to where u want it to be at idle it'll be in poor, etc etc, !! other cars maybe bigger engines will be the other way round they'll idle with the gauge right round to the max!!

firstly are you just taking vacuum from the same place as the dizzy gets it or are you using a seperate manifiold take off?? actual manifold pressure will probably be higher than the readout u get at the dizzy takeoff!!

Just got a smiths one now, sod tim and their gauge! Mine has no levels!

[JoeBodge]

its off of the dizzy vaccum take off - oh well - its only for show anyway - dont really use it.

thanks anywayz

u can buy a carb spacer that has a built in take off!! this should read a lot better on the gauge and its not too expensive!!

[JoeBodge]

ooh - do u no where to get one from?

thanks

i cant find them on minispares site but thats not uncommon, had no luck with minisport either. you could ring either and ask or im sure sum1 has a good idea where you can get them from. they definately exist.

aahh i was searching carb spacer and vacuum take off, i know it was there somewhere - manifold adapter

Yeh, u def need to get the vac from the manifold. Vacuum with vary from one vehicle to another because of compression ratio's , cam timing etc.
