What to expect from stroker performance...

[bugnut]

Okay, I'll admit that I'm now down to asking hypothetical questions because I haven't had time or work space for starting on my 2017 project, but please feel free to feed my imagination.  I'm curious as to what to expect performance wise transitioning from a mild 1776 (Engle 100 cam, 1.25 rockers, dual Kadrons, 7.8:1 semi hemi heads, yada yada yada) into a much larger beast (2017, dual 45 DRLA's, 42x37.5 valves, 8.5 or 9:1 comp, Engle 125 cam with 1.25 rockers).  I've gone for rides in stroker-equipped VWs, but never have had the pleasure to drive one for myself, so I'm just curious as to what to expect in terms of the car's behavior. It's going in a '70 Bug with (to begin with) a stock 4.12 IRS box.  Car has CB drop spindles and discs up front and stock drums out back.

Any feedback from those that have memories of your first stroker build would be great.  Thanks in advance!  Grin

One of my earlier 2017 cc engines was similar:

42 x 37 CB Ultra Mag Plus heads (out of the box), Engle 120/1.25's, Kadrons opened to 46 mm (34 mm vents, jetted by AJ Sims), 7.9:1 CR, 5.4" rods, stock '68 Beetle tranny (4.125 R/P), CB dropped spindles, stock drums on all 4 wheels.

Stock-weight Beetle ran 15.1 seconds on 1/4-mile at 3,300 ft altitude...probably well into the 14's if you are near sea level  Drove very nicely around town and on the highway.
