Stroker engines and stall

[Ed Valvo]

To those who have stroker kits, how much easier is it to spool a bigger turbo? Say you have a turbo with a recommended stall of 3500 RPM on a 109 engine with 231 cubes. Would you be able to get away with a 3000 stall converter?

I went from a ~.033-0.040 over 231 to a 250 DLS stroker by Don Cruz. Also ported lower intake and swapped bowl ported stock irons for big valved GN1's, same 3000 stall converter and TE45a, spoolup lagged on the 231 but now almost as quick as a stock turbo and converter spools with the stroker. But it hits so much harder with the stroker, so 5 psi boost in the stroker feels like 20 psi boost on the stock GN, so it could be misleading that way. I also drive a stock GN around for the easy comparison. I'll probably upgrade the converter when I get a billet 6768 anyways. You can always try it out if you already have a 3000 stall to see what happens to save money.
