It's going to be fun to sit back and see what happens......unless someone offers me to beta test one........

I'm guessing I don't have enough air to see the potential either though.

 

Let me know if you want me to try one of those pumps out.

 

I dont know a thing about their new pumps, but have enough data to tell anyone without a doubt that a Mach 4 is plenty big for any pump assembly one could put together in VP44 case. One can even run a Mach 4 behind a 13mm P pump in a conversion truck without problems.

Years ago we started a project to build a better VP pump. Reliability issues are a major stumbling block. If a guy wanted one to compete with and use one in a very limited fashion, perhaps it could work. Im talking about a few hundered feet on a sled pulling track or a handful of drag races. This is not a statement about their pump, but rather our pump we build 6 prototypes of.

We did not take it the final step and spend even more money to try and squeeze out more reliability as the cost was already in the thousands per pump. Perhaps these guys have it figured out??

Lets see some dyno runs, long term reliability testing, and comparison data to the current stable of VP pumps.

Machining tolerances are measured in .0000" digits on some of the internal moving parts. Adding size to these already stressed parts is a tough row to hoe.

I'm with you , I wouldnt mind being a piggy myself , have a superflow dyno just about ready , sence Don said the 4s are good enough I guess the 6+ will b ok

 

My P-pump is fully adjustable-----It's called my right foot!!!!

 

Yeah but that get's old at times for me...it would be nice to be able to turn it down

At the same time though...it's nice not having to do anything but lay that foot down

I agree and I agree!!

 

Glad I'm not alone

Does anyone know for sure what electronic package they're using? How are they calibrating it?

What about timming advance???????

 

Thanks for youe input Don. I was told 8 x .0016 is recommended, but if my mach 4's were a 7 x .0014 I'd be fine for now. Is it true all the mach injectors are 7 hole just in different sizes?


I need more fuel some kind of bad

 

I wouldn't give up on those 4's too quickly. Look what RowJ and MikeD are doing with them. The 4's are awesome injectors in my opinion. Great peformance when you turn your boxes up, but very well mannered on the street.

 

I wonder how a smarty is gonna work on these big pumps.

 

I can't wait to see a truck run with one of these pumps. It should be awesome with a Smarty, box, and some big sticks!

 

I just hope they work for more then six months being beat on. Kind of like the 14MM head on the VE.
