Hah thanks. But no, not gonna weld it because I plan on improving lap times, not just drifting. Working viscous lsd is just much better than welded diff, with a welded diff you tend to get loads of understeer on turn in and I don't want that.
I'm not on planning on ditching the viscous lsd, because it can be serviced to perform very well. I'm planning on opening the lsd unit and putting new, more aggressively locking fluids in. Plenty people have reported this to have great results.
Problem currently isn't lack of power. It's putting it down. You can see it from the video. Accelerating out of corners is tricky. This is due to the viscous lsd, it needs some servicing because now it just spins with one wheel.
It's fine for doing few donuts here and there but on proper track usage it cant keep up.
Had my first trackday ever last weekend. Was loads of fun and car ran like clockwork (well apart from one of the two alternator belts flying away during the last track session). Also highlighted some much needed improvements for the car that need accessing before I go to the track next time. Hopefully with them next time I'll be able to get more laps in too and improve more on my driving too.

Mah favorite corner:
Then few pictures I found on the net from the event:
And couple of videos I edited. I tried to leave all the boring stuff out (cooldown laps etc) so hopefully you don't need to skip too much.

I actually have the how to power tune pinto book in pdf (IIRC I have two different ones) and they do show quite well what to do.
I only have injection heads actually (one what is actually ported already, but this is most probably going on top of another N/A pinto engine at a later date) and the one that is currently on this turbo car (intake side ported only), tho I think it will stay in the car as long as I have another head prepared and ready to be swapped.
There is just quite a few things that I don't expect to be able to do at home myself. Like proper valve seats fitting to be used with unleaded and double valve springs (I'm also gonna go for a bigger cam the current Burton 134 doesn't quite do it for me). The porting itself is quite a DIY job, but I think it should be done by the same guy who does the big valve conversion.
Maybe at some point in the future I'll start to practice to do it myself but currently it doesn't seem like a very wise option, after all the amount of money saved isn't very big either when you look at the big picture.
Yeah I have been considering it, but there is also occasionally good big valve heads popping up for sale for not too much money (pintos are quite common still around here) so might go for a ready one too.
+ I don't think I can do the big valve conversion myself.
++ I would like to use head from someone who is known to be good at it, since with that upgrade I'm also wanting to start to prepare for bigger bhp numbers. Practicing myself wouldn't possibly get as good results.
Imma gonna photowhore whit some new pictures of my "toy".
I'm only running 1.0 bar of sissyboost now (was supposed to go for 1.5 - 1.7 bar this summer) but upping the boost creates a problem with compressor surge so I have to invest for some properly ported big valve head before upping the boost.
Good thing I have been able to livemap it properly so the overall driveability has increased quite a lot.
Yes I know too much photos of one car but damnit I can't decide to weed out any more of them.
That reminded me of something. Where I worked a year ago at summer, we once had the opportunity to hear a presentation and one of the presenters was this quite experienced sales person. What I can recall one part of his job was to keep up the important relationships with big customers from all around the world.
One of his very important lessons was, that when you are hosting a visit for rich Kenyan businessman, you don't simply lead them to a Sauna's dressing room and start undressing your pants.
Imagining the possible facial expressions makes me still giggle.
It's very hard to judge physics from videos like that. Main problems for me at least are camera effects such as g-force simulation, hand animations and such.
I have found that only way to judge physics somewhat properly is from videos whit a skilled driver using a proper wheel (at least a G25 type of product) and that the recording shows the actual hand work on the wheel.
If that isn't available at least the incar view should have a 100% static camera. G-force effects tend to filter out all the little movements the car does and so the handling dynamics don't really show at all.
I like more natural look so neither of them are quite my cup of tea. But the left one looks like she has anorexia or something so maybe the one on right.
Actually looking at it I think that might be the older PC version. IIRC the one in my Nokia phone looked quite different because of the different screen type.
I heard V6 and a turbo, what's not to like? The audio clip itself is quite short and sterile, but if they wont use very muffled exhausts it should sound quite spectacular.
Altho I've never been fan of the modern type of supernaturally high revving F1 engine so that's probably why I'm more curious than skeptical.
Because it's a good engine management if you know what you're doing and are willing to spend some time DIY. You can get it doing pretty much anything you need but for half the money when comparing to the other systems...
