Boosting a 301 (for fun)

(1/5) > >>

FormTA:

So, I have always wanted to mess around with boost be it a turbo or a supercharger... I know the 301 is not a good option but I have a couple of them. The ones I have are the weak ones too so that makes it an even worse idea but I have back ups. So, hear me out an just remember it's just an air pump so we could be talking about a chevy 305...

The 301 is 150hp give or take. I was thinking about installing a Holley sniper efi system on one here recently but then noticed they are capable of blow through boost. So, let's say I pick up a cheap Chinese turbo for cheap and fined somewhere to cram it in (even if it has to be under or at the rear of the car) and blow through the sniper efi. I am not trying to make big power here just add a bit to the car. It will be a 4 speed stick, so that should help maintain the happy spot. I would be fine if all it safely could do is 3 lbs of boost.  It's just for a tiny bit more fun.

The thing is I know nothing about boosting an engine or tuning so I thought maybe this would be possible if I used a self learning efi like Holley and because there are no efi intakes for the 301 just go with throttle body injection. Also trying to do it cheaply and for fun.

I don't know enough yet about the Holly Sniper setup to understand it's ability to connect and control spark though. I have heard there are electronic 301 distributors from 81 out there. I just don't know if it could control it and would I even need it to or could I just run the old stock vacuum advance unit. I would lean towards the electronic distributor so the ecm can tune it, not me though... or, could I take some other distributor and combine it with the 301 housing and make an electronic distributor that it could control.

And if it all goes sideways I have backup engines.

Any input or ideas on this would be helpful.

I think it sounds like fun. I am not mechanically inclined but I am pretty good at figuring things out. I would be up to the challenge for fun and entertainment! You are pretty good with this kind of stuff and I am sure you can do something crazy with it.

N PRGRES:
Its a 301, you can't make it any worse!  Sounds like a fun experiment!

Luke, this is the guy you should talk to https://ttaperformance.com/my-turbo-cars
Actually I think you already have a relationship. Isn’t this where you get your flywheel from? He probably is the most knowledgeable guy out there on th 301 turbo. He has integrated EFI and run 12.85 quarter miles with his 301 turbo TA.

FormTA:
Ya, I should probably give him a call. He runs them the way they were originally, a where the carburetor or throttle body efi is before the turbo. I want to have the TBI on the standard intake and blow through it. I'm not sure he has ever done that but I'm sure he would know more than I. I was hoping someone who has turbo something or who runs sniper efi will chime in too.
