009's

[bose]

I have a TA 49 and Blue Tops.All my mods are in my signature.I am going to add a stock location stretch intercooler.I am told the Blue Tops may be too lean at higher boost.Will they?If so ,how do 009's work with this turbo?Bruce

I ain't Bruce but I can tell you 83's would work with that turbo.

They might be if you add ported heads and a cam. In that case I would go to 009's or 50's.

I'm not Bruce either.

I'm Bruce,
Ugh, I think I am anyway,

I wouldn't be at all afraid of 72s, and like Steve mentioned 83 might be a good call.

It's really a matter of point of view, if you consider running the injectors static as a viable answer you can get by with less. If you want true Tune ability, then you need to get serious about injector size.

From another post of mine:

Injector size AFR Grm/sec DC RPM
30 12.5 255 90 1360
40 12.5 255 90 1460
50 12.5 255 90 1510
55 12.5 255 90 1560
72 12.5 255 75 5150

Up until you have enough gas to get enough fuel with in a given DC you're just beating your head against a wall, if you want tuneability.

Just look at what happens when you actually get enough injector. With the 72s all of a sudden you have room to play with, and the 12.5 is a VERY CONSERVATIVE AFR.

I just wish I had a set of 72s right now for my car.
If I'd been able to run these numbers a year ago, I could have saved a boat load of time and effort.....

But, I have another answer, that might be even tricker,,,,
