Scratching my head here. New 990 pump, some run time but doesnt actually have a full pass on it. Didn’t have any data on the first few attempts....
Thanks Dave. Seems like the thing they call idle poppet on the square BV schematic has the same function as the pump saver poppet on a k valve...
I’ve never understood this schematic. What is the purpose of the idle bypass.? What size pills do you run in each poppet? I’m getting ready to...
I would expect .007 to maybe .009. wiseco runs tighter than anybody, probably .005 on that bore. i think somebody on here mentioned running .012...
4.5 leaves plenty of material. 4.53 or even 4.56 is fine up to about 2000 hp. Probably more. I ran a 4.6 bore up close to 1800 for a little...
Ya, i stumbled across that last year after having people squirt through the butterflies for years. Almost always at the head of the lanes it was:...
I usually start out with the blades as far shut as they’ll go without binding. Maybe .005 using small points style feeler gages. Those give you...
Sounds like blade gap is a little high. Adjust that and then lean it down until it stumbles on a decent throttle crack. Riches it back up a...
Is it hurting bearings? I used to pull 1 to 1.5 starting around 4 seconds to try to calm down a combo that was unhappy. I never figured out why...
I did a quick calc. Seems like the 6 will be fine with the return poppet right on the pump. Minimal pressure loss at ~8 gpm. It looks small but...
Dragster is currently running NA with Hilborn stacks and a 110 (or maybe 990) pump. I have a 6 an off the pump through the shutoff with return...
Huh, i think I found a pic of the type of blower you’re talking about. Never seen that. Wonder why they leave the front of the case intact;...
Not sure I understand without pictures but if you blocked the front of a retro outlet it has to be killing power pretty good. If I was taking a...
All the parts are on the property, just need bolted together. Im sure I’ll learn something I wasn’t expecting to but that’s part of the fun...
I’m going to try something here shortly. Small opening inlet on a 14-71 hhr. If cylinder head flow principals mean anything; inthink people say...
Thought sure I found the smoking gun. Figured out I could lock timing at 20 instead of 0 and if I put my inline coil tester on #1 it will fire...
I’ve read about diesel guys using a hoop with no gasket in between. Think a visner ring in the block with the head clamped down would be...
anybody ever tried this before? Like an Sce Vulcan setup except the oring is round.
Ron, this is CNP. No rotor. I’ve had this same BV on 3 or 4 different roots motors with 3 different 14s. All of those made more power than what...
Mike, I think it’s the same idea. I saw where Holley or maybe big stuff you can change the value of the timing lock function that allows you to...
