New article up!
This time is a brief guide for turbocharging using the 1975 technology.
Great guide! Nicely written and well formatted, definitely looks like it could come from an actual magazine!
I have never been able to find any success with low A/R ratios, however. The torque curve always peaks early and then drops, and horsepower suffers as a result. I have no idea how you were able to achieve identical torque curves with two different A/Rs, haha.
Do you think you post your engine with a few different variants for us to play around with?
Different turbocharger sizes on both compressor and turbine.
That is right. With the first two examples, the first one uses an AR ratio of 0.82 a compressor size of 50 and a turbine size of 50.5 with a medium intercooler. The second one uses an AR of 1.04 a compressor of 50.5 and a turbine of 40.5 with a large intercooler.
Remember, with an AR ratio lower than 1 you need a larger turbine and a smaller compressor. The disvantage of using a lower AR ratio is that the boost will fade out quickly in comparision to a larger AR ratio.
Here are the engines used in the article for you to take a look.

My small turbine/high AR version of the Eco engine:
Gets slightly better performance with 19.8% efficiency vs. the original 17.6%. The turbo spools quicker at 2100RPM vs 2300RPM and boost lasts longer through the torque curve. Costs are lower because I switched from throttle per cylinder to single throttle.
41mm compressor - 32.3mm turbine - 1.16 AR Ratio - 0.47bar boost
That’s a nice engine with a high economy for 70s standards. I forgot those engines have individual throttles xD.
Anyways, next close encounter is here. I was supossed to publish it yesterday but life happens. This is the 8 out of 10, so first issue is almost done!

as always, another good review, keep 'em coming
@cpufreak101 thanks 
EDIT: oops, wrong user name 
On to the next review!
I had a hard time finding cars that actually aligned with the body correctly, so bear with me with the pictures

What a fantastic review of the Civera. Thank you so much!
@DeusExMackia Well, thank you for sending it 
Next article, the decade of the communitasia!
With this, I close the first issue of the magazine. I was going to add a buyer’s guide section, but there is not much case now with the buyer’s guide thread. I’ll upload the full issue in a zip later. For the moment entries for the next issue are closed, as I want a to take a break from the magazine to finish some mods and to actually play some automation! thank you to all who send their cars and thank you to all the readers and commenters

love it 
@cpufreak101 Thank you. You know what’s interesting about the communitasia? It has the highest value/price coefficient! Almost twice than the previous cars that I reviewed (the Civera and the Combat). You really get a lot for that price.
In other news, links to download the full thing now in the OP.
@Sillyworld well then, guess i’m good at cheapness then lol, but anyways, now the question is, what’s the next issue going to be?

This is a fantastic collection rolled into a full issue. And produced so quickly too. Will you be planning to go through all the decades progressively?
well i just realised there’s a gold growing in here.
so i’m guessing the first volume are done?
i might try to send a car next issue since only recently i’ve finally gone active with my car company again.
Silly should take a break, not to burn out. His projects seem to be humongous.
Don’t know yet, maybe I start receiving entries in a couple of weeks, but I’m not sure yet, but squidhead is right, I want to take a break before I start doing the reviews again 
Thanks, it took quite a bit to get it done and that’s correct, I want to ver all decades (70s onwards) progressively. I was planning 3 issues per decade, but after seen what it takes to complete a full issue, I will do only 2 per decade instead. Next one will be still 70s cars and early 80s.
But I’m not taking entries yet

Any updates on this? I know you are taking a break but what is your current state? 
Using my genious intellects I have deducted that Silly isn’t taking entries yet. Im Sherlock like that.
