Blowers

going back to what i asked befour and i guess you are the best qualified person to answer this

what is the hp difference between the first K11 based units and the complete DMPE versions of the M5 if any?

cheers

Graham

 

The DMPE case and the X3 rotor produced 125 hp over the Kobe case and K11 rotored M5. This number has been confirmed by DMPE and two other testing facilities.

Enjoy your day

how does the ssi blowers compare to the rest

 

Thanks for the info Darren

I had an early M5 and as you know it was quickly superceeded, It
still cost the same as your currently advertising $13,500 for the complete deal,

im sure you understand i was prety pissed having spent top dollar and ending up with something that was less than "the best un modified blower on the market"
i got lucky and sold off all my equipment inc the blower,
and re equiped with later stuff, but as part of the constant battle for performance im once again looking at buying a new blower, which is why i asked about the billet stuff,

is the development of the M5 now complete??
id hate to be in the same position again

Regards

Blower displacement

Darren,

On another thread you previously stated the following, "Each inch of Rotor length nets 14.4321 cubic inch of displacement per revolution".

What I would like to know is how you arrive at that number and under what atmospheric conditions do you arrive at said number? Does this number change for various weather conditions or is it purely a mathematically arrived number?

In other words, I don't see how 548 cu. in. displacement at sea level would be the same at 4000 DA.

If there is a difference, and I think there is as far as a tune-up is concerned, is there a formula worked up to compensate for various weather conditions based on a known standard?

Thanks,

Robin

It will never be complete. I am always looking to improve our products. The M5 that you purchased was at our best at that point in time. And I do understand your point. However a bit like computers, always improving. The M5 has now settled in and changes are slight. Small changes to improve or further perfect, bolt in or on sort of items.

I’ve always got something im messing with, right now its screw and other new products on my plate.

Graham also I gotta say I think you car is very cool. That body seems to be loved or hated. I’m on the Love it side of the fence.

Mike: i am happy to hear ole Jonny is taking care of you. We appreciate you.

Cheers

I dealt with ERD and Salemi recently, both provided an excellent service and got me what i wanted when i wanted no fuss. They had my broken rear end converted to a flater in one week and back to me to make the next event!

In todays market it is nice to see companies that take care you and provide a good service.

Thanks Jon and Carl!

That number is the mathematical swept volume of our rotor. Look at it as the cid displacement as you do your engine. Yes atmospheric conditions affect everything that displace a gas. The engine, the blower and also our lungs. The math to calculate all of the changes required to perfectly equate all possible atmospheric conditions would be very involved as you can expect. There are many ways to go about this and most tuners have there own way of doing it.
To me this is the fun part of running a car after all the hours of work preparing it for competition.

Good luck

Darren

 

Ok thanks for the comments about the car it realy gets everyones attention here in europe, and the factory type paint job help with the overall effect a lot,

Sure i realize that development is never done it was just unfortunate that you changed both the rotors and case so all my stuff was obselete,

anyway thats the past i guess what im asking is when further developments occur will they retrofit the older blowers im thinking that unless you drasticaly change the case or rotors again anytime soon then they will and it will be able to be upgraded at a price of cource,

shall i talk to Jon about delivery dates payment ect

thanks
Graham

 

AJPE Billet cases

Chuck Ford makes the Billet cases. Also what some may not know is Alan Johnson is making Billet cases as well, Just the case not the bearing plates. I would say listen to DMPE they seem well respected in the Pro Mod market. Thanks for your post Darren.
