manual boost controller

im not sure if my turbo is putting out as much as it should ive been told that 13 psi is max for my little 2.4 unless the fuel is upped, but i wouldnt have a clue what its running at at the moment i just think it should have more of an effect when it gets going i will have it tuned once i get everything in i have a intercooler bov oil catch can and boost controller going in maybe even a snorkel down the track

I thought that the whole idea of turbos, supercharging, NOS or whatever was to force feed more air into the combustion chambers to enable the engine to burn more fuel.

You can run as much boost as you like, but if you aren't adding additional fuel, the engine isn't going to make any more power. BUT, the more power the engine makes, the hotter it gets, so if I were you, I would be looking for a pyrometer to measure the EGT as well.

"i have a intercooler bov oil catch can and boost controller going in maybe even a snorkel down the track "

Why fit a boost controller and a BOV (blow off valve)?
They both do the same thing in a different way?

i thought a BOV just dumped the extra pressure when you get off the gas

and a boost controller controlled the max amount of boost the turbo put out

Nah Dirty, the BOV is just to stop the turbo stalling when you get off the gas in a PETROL car. The throttle butterfly slams shut and the boost charge slams into it and stalls the turbo during gear changes.

The BOV allows the boost to escape but doesnt slow the turbo and allows faster spool up when you get back on the gas after the gear change.

Not needed in a diesel...no throttle butterfly (apart from Jap imports)

You will be fine with the boost controller but I do recommend getting the boost guage fitted first so you can see what yours is (or isnt) doing and make minor adjust ments yourself until you get the intercooler fitted and a good tune up!!

Sounds like you are having a blast!

sounds like a good idea with the boost guage unfortunatly i do have a jap import (Surf) not sure if it has a butterfly though.

and your right having a great time just bought it for 3 grand and then spent another 3 on it new front diff plus lokka suspension tyres and a duel battery system with 2 new batterys my mates giving me his old intercooler (as soon as he gets his arse in gear) another mate workes in a place were he can make or bend pipes for the instilation should have it all in early next year.

took it up the bush the other day to some good hill climbes and i remember last time i was there thinking i wonder what 4x4 could make it up that big steep narly ruttud track. MINE yay having a ball

nah dont stress, that was a tad tongue-in-cheek bout the throttle butterfly.

Some jap imports have an emmision butterfly in the cross over pipe. Isuzus do but not 100% sure about the surf. Nothin to worry about.

Sounds like you are on the right track to a great little truck anyway.

Glad to hear you are happy with your lokka, there are so uneducated scare mongers out there baggin them on the advice of a friend of a bloke they met down the pub one day 23 years ago......

They are great with buggar all drawbacks and endless benifits!

hi john its a diesel i wasnt 100% about the BOV but i can tell you i do need a catch can theres a lot of blow by and a lot of oil going into the air intake

you absolutely, definitely WILL need a catch can on your 2.4 (surf?)
Make sure the fitting and hence flow are at least the same size as the existing crankcase vent pipe.

i have read up on catch cans and diesels a lot of extra blow by if piping is too small you will pressureise the engine and break stuff

yes usually the first thing to go is the turbo seals, but could also be the crankshaft seals

Forgot to add.
I also added a boost guage to see what was happening before and after.
Also and EGT, and I find I have to watch that the temp before the turbo doesn't go too far over 600 deg, especially up hills. Might melt pistons :o).

what is a EGT

EGT - exhaust gas temperature guage.

On a diesel you can keep turning up the fuel for more power, well to a point, but that point is higher than a petrol.

And more fuel gets to a point where you are creating a lot more heat, but not a lot more power. You cam melt pistons. Hence the EGT, checking the temp of the exhaust gases.

Technically there is more to this than I have covered, but I think you get the idea.

learn something new everyday thanks

There are some good technicalarticles on this site.

Have a look at "why diesels are different".
