since putting s/c gears on my 1275 turbo it doesnt seem to have as much grunt when the turbo comes in as it did before,is this because of the gearsor what???

It should have a little more. not that you would notice unless on the RR

Two things are infinite: the universe and human stupidity; and I'm not sure about the the universe.

maybe because of the different ratios it feels slower

could be,its just it doesnt feel theres as much oomph when the turbo kicks in,than what there was before

maybe there isnt......

you have had it in pieces, could be a chance you've disturbed the timing or something.

ive only had the box off,nothing more. stuart at vmax set the timing again for me,so cant see whats different

fair enough just a thought

must be a "perception" thing then and nothing else. only way to find out really would have been a before and after 1/4 or something like that to gauge performance.

Nobodies hid anything heavy in the boot have they

lol yeah probably just the thought

wondered what that anker was doing tied to the bumper lol

dan
this may sound silly but have you checked your tyre pressures ???

as i have said before give it time to bed in! this will
sapp a few gee gees

also the straight cuts by the nature of the design are more power robbing than helical gears

could always take it back to minispeeds rollers ?

dan take it to stuart and let him roller it

yeah, when can you fir me in stuart??? emai or pm me.

ps ive sent you an email about turbo head

fire the head on and roller it at stuarts

i basically want a head thats ganna give me a decent power increase,i wanna run 10psi without a cooler for now,got about ?400 to play with. whatd you rekon the average powet gain is for say a stage 3 eqivelant or a hot turbo head?

turbo heads dont need to be hot, do a search and there was a very long thread about the ins and outs of them

can't seem to get the pm or hotmail to work ,
tuesday ?
give me a ring

dan wait a little and do it right

please DONT forget THE MOST important part of your TURBO motor

THE INTERCOOLER

ok then,so i should get a head that is capable of say 10psi when the intercoolers on,but run it on say 8psi until i get the intercooler fitted yey?

or could it be run at a higher psi,say 12psi with a cooler??

give me the specs guys!


cheers for the help

stuart,think il put the rollers on hold until i get the head,otherwise itl need doing twice.

another thing,the adjuster nut on the fuel reg is loose,could fuel pressure be something to check, and is 3.5psi the setting it should be at?

wants to be spot on yeah, between 3.5 and 4.5 will do nicely.

fuel press reg 3.5 to 4 psi above boost
so set it static with pump running then it will rise the same above boost

10 psi ish the limit ish with no cooler

add a cooler and its like adding a extra cylinder

same boost but you will will be able to run higher boost figures say to 14 15 ish without detenation


do a search on intercoolers and get genned up dan

also on compression ratios

some ones selling intercoolers on
for sale section

Edited by BENROSS on 12th Mar, 2005.

So just whack the fuel reader on the pipe,turn on ignition and turn the adjuster until 3.5/ 4 psi is reached yey?

yep

so stu,what head would you recomend for the above requirments??

i must have more power,i must!!
