A cam

Stock down pipe only and 3 inch back (3 inch sports cat and silencer)
Ram Air
Moved AMM to just before throttle body
Stock fuel system

Afr guage sticks around 14-15 cruising
Flooring it drops to 12-13
From time to time does go upto 16 but comes back down.

Question is would it be safe to run it at 20psi?

i for got to add, it also has a fuel chip

Thanks for any input

Why do you want to run 20psi? Like, just because or is there a specific power goal you're trying to obtain?

I'd maybe suggest a different approach. The high compression engine is going to limit you in terms of the amount of boost you can safely run on regular gas. If we start talking E85 then some of this becomes less relevant.

What intercooler are you running? Stock volvo intercooler? Kenny has shown dyno proven like 20 wheel hp gains by going to the do88 unit.

That A cam is pretty meh. An enem 15V or 16V would give much better results than an oem emissions cam.

That stock downpipe needs to go.

The AMM needs to be moved over to pre-turbo so it will get an accurate reading. It wasn't really designed as a blow through and that ebay 50 trim is going to probably seep some oil that would be better to not get on the AMM. An upgrade to a 3" AMM is possible.

Couple the 3" AMM with some orange/white/blue/green top injectors from a FWD turbo car so you've got enough injector. You'll want a bigger in tank fuel pump too. Walbro or DW200/300. Upgrade the intake pump to one of those and then you can throw that under the car pump set up into the woods where it belongs.

If you're sticking with LH you'll want a chip for the ignition side too. Need to pull the timing back up high(and probably down low too but the 50trim maybe spools slow enough it won't ping down low).

The intercooler and cam upgrades alone would probably make more power at 12-14psi than your A cam and oem intercooler at 20.

If you are measuring the air going in, You have to recirculate the dumped boost because that is measured air. If you dump measured air it will over-fuel.

You will get much more helpful responses when you know a bit more about the different ways we have solved these problems. Then discuss which might be the best for you. If you are on a tight budget, save up a bit before the next move so you don't set yourself back with the ventilated block mod.

Generally no one here just hands you the answer for a question that has been asked a million times.

You don't need to blow through the MAF unless you are using a blow off valve. It's not ideal to have it after the turbo unless you really need to.

Exactly, what they said!

Also, there is never a need to personally attack someone on any forum anywhere. It's futile and unnecessary. As corny as it may sound, we should treat each other the way we would treat a cloned version of ourselves! Because I can't wait for the day I can clone myself and have him work on the car (while I berate him personally for (doing it all wrong!")

Honestly, I'm just glad this (Volvo) scene is still alive. #grateful

My apologies if I was toxic. This forum has always been very helpful to me and I have learned a lot. I have found I get better responses when I do a little research before I ask a question.
