The singles were getting valve float at low revs with boost
The reccomend springs for that cam i think have 90lbs seat pressure .

Have slowed down a bit on it already due to having a couple of other cars of interest in the shed.
. The mk1 could be up for sale just need to find time to refit the cylinder head.

It needs a good detail
But the cylinder head is finally refitted and its going again

update.
Have done all the tuning with the microtech and very happy with the driveability over the old blow thru carb ( which wasnt too bad just no where near as good as it is now)

Put it on the dyno for a power run
Wastegate set to 10psi. And sounded great all the way through feels really good on the road very clean throttle response

Pretty good results for a stock pinto only mods being the 26661 cam and dual valve springs and the home made efi setup.and ofcourse the 300 dollar China spec turbo ramming close to 11 pounds off boost down its throat.

136.7 rkw first pull

It has gained alot down low. the response straight from idle is now really good and the power just rolls on so much quicker than it used to with the carb no noticble lag on the road just instant power on the crack of the throttle .also
No more excessive rich cruise mixtures like the carb use to have. Couldn't be happier with the new found driveability with efi

I have another boost setting to try just couldn't do it on the day so will be running it up again very soon hoping to get close 150 rwk at around 14 psi.

Will update in a couple weeks when its been back on the dyno with a bit more boost.

Boost has been turned up to Around 1 bar
Ready for another squirt on the dyno.

My mate filmed the boost gauge while trying to keep steady which is not always easy!haha .response is great with the new setup

not that the camera can justify the true noise, always sounds different  on camera but here is a link of the dyno vid.

Turbo's being in series with the exhaust system act as a muffler. It would be nice if they could sound like webers ;)

I disagree. in person they sound better.
Nothing better than nice quiet ish cruising then when that boost comes in and that gate opens. It soon out does the webber roar not to mention more power easily.

Agree with your comment on a low boost internal gate setup ( like a stock saloon) the noise is just.not there. Trust me in person they sound great in anger.plenty off rb or 2j powered vehicles out there that sound pretty dam good once they start making boost snd a few revs. The link from dyno was filmed with a go pro half way down the workshop and it just doesn't capture the roar the engine makes when the screamer opens. The in car one filmed with mobile phone gives a bit better idea but still nothing like the real thing.

And yes i do love the induction sound from webbers or throttle bodies. But why would you bother in a performance per dollar scale these days. Unless its for a certain class off racing .

Still not webbers but try this one.
Bit more boost makes a bit more noise
It also made 159.9 kw @ wheels after the boost change.

thanks mate, for the kind words, it has come along way, I have future plans  with the car have only just started playing with efi, there will be a lot more to come yet!!

Have driven the car to victor harbour and return last weekend,
first time have driven it on the highway with 100km/h cruise speed  was a little concerned if it would be happy sitting at the speed on the highway only having the 4 speed,
 
couldnt ask for a better cruise car, we cruised at 100km/h (speed limit for highway) for the entire trip even overtook some late model cars that were failing to atleast do the speed limit.
 
largish dia tyres (24inch dia 225/50/15s) it was quite comfortable on the highway speed limit engine was doing  just over 3000rpm, water temp was 88 deg and down to 86 on some of the downhill runs. 150 km return trip no problem and only used 1/4 of a tank. couldn't be happier with the amount of use the car is good for.
