For a smaller displacement street motor, go with a .81-.96 turbine A/R and a decent compressor size. I bought the 1.05 A/R housing and it spools SSLLOOWWW on my 318. I wish I would have known more and I would have got something smaller.

That's where I don't agree. Mine is a 1.32 A/R and a 96mm wheel...

With a 2600 (on motor only) stall. I could foot brake 1200rpm into the beams, grab the trans brake and floor it as soon as I staged the car. I could be to 10psi before the bottom bulb went on without an issue.

So zero boost to full boost in 1 second. I can also go from 8psi to 20psi in under a second after a I let go of the trans brake.

Just depends on what your definition of "slow" spooling is I guess. But mine is not bad at all in my opinion.

Here is a video of mine from rolling on the throttle in the car... you can hear it doesn't take long to spool up at all.

Here is one from a roll in first that I flat foot it. (you can hear the big ol' pedal hit the floor... lol

That being said, after I tightened the converter so it will only go to 2200rpm on motor, it's absolutely TERRIBLE on spool up. But I blame the converter, not the turbo A/R.

Just like anything, you just need to match the components to make them work good.

I imagine mine would spool well on a tbrake but off the footbrake with a tight converter it sucks

I believe that!

Plus with the 318, it isn't exactly a torque monster without the turbo.

It's winter here so I won't have any updates till spring.
M1 is VP Methanol for those that think it's a intake.

If your still building boost but it topped out you need a bigger exhaust housing, or complete bigger turbo

Oops World series 2013, but we will be there in 2014

Really liking the idea of putting a turbo on 383 in a slick old f5 belvedere 1 4door. Any advantages/disadvantages of using a 4 speed with that engine set up?

4 speed won't build boost as easy as an automatic will. No converter to load against at the starting line, no "flash stall" to make RPM from a roll.

I meant 65 not f5. So if I was to use a basicly stock engine, small cam, would a stock convertor work? Say a 2200 stall?

Just depends on what you're goals are. But if you keep the boost down, it won't break parts.

Anything will make power with boost. I think quickd100 has proven that.

Stock 318...

A tight 3500 stall made a night and day difference in mine.

But I have a Comp 280,480 cam in it also.

It's been ages since I've been on here.

The budget turbo Belvedere is still kicking, Msd 7531 box, C&S Aresol and a much larger turbo.
383 is still basically stock.

Hopefully I'll get it back to the track eventually!

Welcome back

Cool, glad to hear the old Belvy is still running!

Here is a pic @ Cordova for the World Series 2015. 62 years straight.
Last time they had that event before new owners moved it.

Foot brake column shift bench seat.
I melted the stock cast pistons before this launch.
I warmed it up on the return road.

My timing map was messed up somehow.... O well

I think the old girl held up good to 7 years if 20+ lbs of boost non intercooled.

I posted in this thread back in 2013 regarding my future 383 turbo plans for my '69 Super Bee... though Id share that I finally built mine and took it out for its maiden voyage just a few days ago.
