mini build
Turbo Mini Forums

i have counted the gaps and peaks, it is counting every tooth however on he composite log it shows a few of them paired up
i spent almost an hour tweeking the the threshold and hysteresis pots (R52, R56)
made no difference to the logs

sorry for the quality of them tm wouldnt let me upload the jpegs

this is the failed starts


this was a random 4th gear pull

256Kpa !!!

I make that 35psi+ - and it sounds very scary

I get 22.5psi

Hey Brett. The jumping out of gear when agressively closing throttle could possibly be down to the engine rocking? If the engine is fixed well with lots of steadies (all with good condition bushes ect), it could well be in the gearbox.

Just had a read through all of this, looks really good. Like the bonnet and exhaust!

Thanks for the education, guys, I am still on the upward learning curve here.

swapped the actuator over today, ive ended up using a modified GT17 unit
before fitting i thought on and measured the load required to pull the actuator rod
stock GT17 - 7.6kg to move it 8.3kg at the end of its travel
stock GT17 - 8.5kg to move, 9.2kg full travel
stock GT20 - 18.5kg to move 22kg full travel

no wonder i was getting 23+psi spike and settling down to 18odd psi

i acquired 2 GT17 units both different lengths/size strength but i had to modify the one i used i ran a die down the rod 3 inched further and chopped 2 inch off the end as itr was very long

Good news Brett.

Although I don't know why you'd want less than 20 psi ?

In the 13's at last!.. Just

3d mappable boost cant go lower than the base actuator boost

and to aid tuning the needle at 20psi i darnt take my eyes off the road

Oohhh, fancy.

In the 13's at last!.. Just

finished building this today works like a charm,
did not realise the carb is not central in the engine bay, so the hole in the bonnet looks like a pair of balls lol

tryed out my diy corner weighing scales, very impressed with the results and gave believable and repeatable numbers it is officially 633KG with almost a 66% / 34% distribution to the front
may have to rob my dads garage for the day to tweak them properly and do a geometry set up on it

Have you tried just plumbing the actuator straight into the snail with some 6" long pipe? Just to eliminate the chance of kinked pipe/faulty valve?

Ps the log goes straight over my head

It might be worth whipping your downpipe off and doing a bigger dump tube, can't see it making it worse? Got to be worth a try.

the dump tube is now 2inch mate look closely at the last 2 down pipe pics i posted
the s/steel flange has been opened out to the exhaust gasket too

Oh I see, so have you ground the flange to join them together?

Just re read your post when I wasn't half asleep lol, I may do the same with mine then.
