OST-047: Skippy Replicate
Remember Skippy?? http://www.aeu86.org/forum/Thread-OST-03...ets-a-head

A quick refresher, I bought/built Skippy(FX16) to be a commuter. When I bought her the engine was junk, and I did a rebuild with the express purpose to maximize the engines torque curve in an effort to maximize fuel economy by having more power in the mid range to allow a shallower throttle angle while on the highway.......

Well, I ended up not needing the commuter and I put her up for sale. It took a while ($3500 FX16 typically does), but I sold her to 2 people..... One person bought her for her engine.... the other bought her because her chassis was in very good shape. Well, the chassis purchaser doesn't want to give up Skippy's engine! Meanwhile the engine purchaser wants his engine!

The engine purchaser will be using the original Skippy 4AGE for rally purposes....

Sooo... I've been commissioned to replicate Skippy's head..... so the chassis purchaser can also enjoy a FAT torque curve Wink

from another forum Wrote:cool to see a clean street FX16. Sad to see this one get 'unplugged'

so this is a 10.7:1 TVIS bigport .....with TVIS working ?
Torque looks beefy(for a na 1.6) from down low. Would be interesting to see a stock torque curve overlay/comparison
I'd imagine the FX drove strong?


close enough... (actual is 10.77:1)

how about a side by side????

Dyno on left is admittedly just from an advertisement.... but it is published data. With that said....... ( I hear some of you rolling your eyes.... Angel )

Whether or not you like the above comparison.... The FX drove very strong.... tough to get it to hook up in 1st gear Big Grin




This head is very dirty... but it is still uncut, and the cast(core) shift isn't too bad

Intake valves aren't too "skanky".... the exhaust on the other hand.... that can't help flow Confused

Intake side.... and chambers now shaped

Ports themselves have changed very little, only a tiny bit of blending, while the bowls and seats got worked - this is to help increase port velocity.

Chambers are all now deshrouded, once it comes back from its valve job, I'll set chamber volumes and finish the chambers
