What size are those 5's?

Anyone know the size on a mach 4? 7x14?

It matters not to me how much it promises to make on #2, If the thing is no more reliable than a standard VP it is useless in my eyes.
Unless you have bottomless pockets.

very true but the one thing i have learned in life lol is that its hard to have reliable in the same sentence as drag truck or full blown pullin truck. i guess thats the reason 99% of shops and manufactures dont sell a warrenty with performance products. now that does not apply to everyone as there are people that do warrenty for performance and i am not saying its impossible to have a super high performance vehicle without reliabitity, it just takes MAJOR money to do it the right way i guess thats the best way i can put it. dont take this as an insult cause its not, just sayin my .2 as well.

 

Sounds like it'll be basically the same in reliability but if you have a proper supply side fuel system, there is not a big issue with the VP. That is why I went with a cam with a lobe to drive the 12v lift pump.

 

You'll want to consider valve springs when you do your cam so you don't float a valve. That is if when you did your head, you didn't do high peformance valve springs already. Just something to keep in mind.

 

springs will go with it for sure

 

Mach 4's have 7 holes IIRC. From what I remember they have the same hole size as the 5's and 6's. The hole size is less than you would think...

 

while I hope to see this "bad-daddy P-Pump killer" as much as anyone, I'd like to point a few small things out.

1) I know people who have P-Pumps that move so much fuel that it would make you deficate yourself, and even with some pretty retarded windmills, 900 reliable HP is no easy feat........800 streetable HP is not simple, so don't think you can call up your local megalo-mart and order you up a buncha parts and make it work. If it were that easy we would all be running 10's.

2) I have been hearing stuff about this pump for a while. It is fairly common knowledge that it is possible to make a VP44 flow a boatload of fuel, but it becomes terribly unreliable when you do so.

3) Think about how many trucks that you know of making 900 on fuel... Okay how many at 800? 700?......... Point is, there aren't that many, and if you think that 750 is street drivable, your name must be Joey Chitwood. I have ridden in a 750+ HP Prostreet truck with a PS driver and lemmie tell you, he was used to the power and it still was waaaay to much to drive around with. We were blowing away drag radials at 1\10th throttle, and an untimely sneeze or big fart could cause the truck to swap ends with you.

 

This sounds interesting, anyone hear anything new?

 

good message but its just a nice feeling knowing that they are coming out with new stuff for us VP guys that will have the ABILITY to make those kinda numbers on #2 only. of course i know it wont be a bolt on deal that will make 900hp righ out of the box but if it gets us close, then i am all for it. right now the highest HP VP truck on #2 alone has done 700.1 by Idaho. thats the highest with just plain jane #2 and if these new pumps will have the ability to go higher, then you just show me where to sign up lol. i dont know, i guess i am just really really partial to my 2gen and love them and hope they can compete with the 12v p pumps and now high hp common rail guys. i mean you can make high hp on anything with the addition of No2 but i would love to make HUGE #s on fuel only.

 

Right, but the beta tester for the new pumps olny cracked 7 bills right? I would just like to see a bit more before I jump on the bandwagon

 

It's going to be hard for anything to compete with the fuel available from the p-pumps. CR guys are running 750-800 and can turn boxes down and street drive reliably and less smoky. I don't think the VP will be as clean as the CR trucks because timing isn't controlled at the injector like the CR's. The VP's will only be as reliable as the std VP Bosch pump, but likely less because they'll be working harder. We all know the old adage, if you are going to play, you'll pay. That is part of it.

It's just nice to know that we as VP guys aren't being completely left behind at 600-650 hp and have a chance to compete with the other trucks if we so choose. Still, it'll be hard to make that jump if these new pumps are nasty dirty or are not reliable as now I can street drive and tow confidently with my 600ish hp truck. There is hope for us VP trucks and it'll be interesting to watch the beta phase of these pumps and as they roll out into the market to see how they perform. Just good to know we aren't completely red headed step children....I guess that title still goes to the Ford guys......

 

ture but there are more than one person makin these pumps and yes they are being beta tested

 

Like I said...the only test results up until now prove that this pump is just as capable as an SO pump... I'd like a bit more data than that

 

i agree with tim. it is probably too early to tell. i hope it does work and work well. maybe this new pump could bring more to the table as far as reliability, new electronics, new injectors, boxes, etc. although i wouldn't need one, my so pump flows more fuel than i can use right now. i hope it all works out for the technology of it.

 

i see what your saying i guess i am just being very optomistic as i really hope it workes out for us VP guys.
