drag only 57 Posted July 5, 2017 Report Posted July 5, 2017 Full drag ported Alcohol 7mil drag motor 2 thru 5 overide, just freshen'd up and everything polished. I am selling for a customer that has a very fast 421 I built him and he's selling because he says it's to fast for him. This is an exceptionaly strong running motor, it won't disappoint! 39mm keihin alky carbs, V force, billet intakes direct drive lockup $3,500 plus ship. I have pics on FB but to large to load here I'll try to get some up soon, if someone knows how to do it from my phone let me know. Quote

Cause I'm pretty sure 7mil 73mm doesn't equal a 421....Sent from my LG-D722 using Tapatalk Quote

PaymentPlan Posted July 5, 2017 Report Posted July 5, 2017 Why do people drag port a PV? That's like putting PC'S on a Cub. Sent from my SM-G900V using Tapatalk Quote

Sent from my SM-G900V using TapatalkDo you have any idea how powervalves work? A drag ported cheetah is not like PC pipes on a cub at allSent from my VS990 using Tapatalk Quote

A drag ported cheetah is not like PC pipes on a cub at allSent from my VS990 using TapatalkWhat I mean behind that is why drag port a cylinder that has PV's, intended for a smoother power delivery. Why throw PC's on a Cub when it's meant to have Sharears? Metaphorically speaking.Sent from my SM-G900V using Tapatalk Quote
hercalmighty Posted July 5, 2017 Report Posted July 5, 2017 Well that's kind of the thing with powervalves. When the powervalves are down they mimic a low port and when they open they mimic a high port. When you drag port a cheetah you will lose some bottom but it's not like drag porting a serval. Your "metaphor" of PC's on a cub is way different. The Cub has fixed port timing set for a "drag" pipe. Putting a "woods" pipe on is just choking the motorSent from my VS990 using Tapatalk Quote

ClaudeMachining Posted July 5, 2017 Report Posted July 5, 2017 Hummm... Dunno what he really mean, but using power valve engine for drag is useless. Drag engine is on/off, no need for powervalves to had bottom. .Envoyé de mon SM-G935W8 en utilisant Tapatalk Quote

special06shee Posted July 5, 2017 Report Posted July 5, 2017 Top end( peak power) only wins races on PERFECT passes. Anyone that is a true racer of any kind will know that a perfect pass is like a unicorn... a broad, more forgiving power curve will usually take the win every time. Quote
special06shee Posted July 5, 2017 Report Posted July 5, 2017 Now im not saying a 80hp board curved motor will beat a pipey 110hp motor. Quote
PaymentPlan Posted July 5, 2017 Report Posted July 5, 2017 535 PV on pump. Nothing about this graph serves a drag purpose. Looks like good competition for a super serval. Sent from my SM-G900V using Tapatalk Quote
