Intro
In the next series of posts i hope to touch on some of the beastly builds going around. I gathered some info from the forums as well as Facebook. I hope these builds uncover possible configurations of the Colt. People spent a lot of time and money to make these various configurations work. Researching parts, RnD, fabrication etc.
More background information on build here, work in progress on updates

Judas
Roller Dyno @ 180fwkw
- EFR6258 @19psi (plenty more to go)
- Forged bottom end
- Jem's fabricator custom manifold to suit
- stock head and cams
"Basically boost pressure is opposing the valve spring, the valve doesn't close correctly, this results in inconsistent power output, sensitive to tune, and worst of all you don't make the power that it is capable of. thats putting it simply."
- A fellow Rcolt Modifier "Georg" Pointed out that it could be spark blow out.
"the spark is not strong enough you lost power @ higher rpm´s, the mixture clears the spark"
"have not tried it, but my tuner has noted it that it can be possible by horsepower over 300....the valve springs can make trouble, too @ higher rpm"
If maybe causing the inconsistent power runs
One difference is this manifold has gone for long runners, whereas Jems has gone short runners.
It is a similar design to my manifold custom made by Matt.
Love the lobster claw dump pipe.
