Don't worry about getting my respect. I just want to know who you are. I like to know who I'm not going to buy engines from.

Show some of your projects.......................................

Well then, that statement clarifies it all, IF TMP had bent someone over, dont you think it would have been all over the board? IF TMP's new 1600's dont perform, dont you think that this board will be first to know? Not one customer has said one negative thing about TMP, excluding open 72, and thats a mute point. Arguing theory and asking questions like that to try to catch someone in a slip up was what won Marisa Tomei the oscar in my cousin Vinnie. Your trying to protect people from being "bent over" and no one has been. Your arguing numbers that you say are unacheivable.

All I meant by that statement was that I understand blower eff. more than most people.
Where do you think whipples came from. Why doesn't Merc call their blowers whipples.
What kind of blowers do you think Racecrafters uses--they seem to be a litter bigger than Dustins.
Racecrafters bought all those blowers when they outlawed them on top alky drag cars---the reason why way too eff. Roots blowers couldn't compete.
A round blower or turbo is the most eff. compressor you can get--they just have to be spooled up to work.
As far as TMP working with Dustin It's because whipple is treading uncharted territory too.
Maybe someone can ask Dustin why his whipples aren't bigger
And if the company he gets them from will ever sell him bigger ones.

If your guys want me off this thread then see you later.

thats not the point, the point is R&D, obviously you have experiance, and if you choose to remain anon, thats your choice. The whole point of my other post was, that people need to chart the uncharted. Of course Dustin is working with whom he feels comfortable with, same as other boat manufacturers are working with people in R&D as well. I'm quite sure Reggie and Sterling have meetings and are trying experimental things. It doesnt matter to me who you are, I think your posts have been good.If you have an idea Talk to Steve and Eddie about implementing it. I fell if they make that HP, thats great, somoen somewher will come up with something better. I remember when turbos were looked at as time bombs as well...Rob

Lysholm needs to make a bigger blower.

While what you said is true, I would like to expand on this comment a little. A "blower" needs to be more thought of as an engine, assuming 100% adiabatic efficiency, a "blower" will move x amount of air at y amount of "blower" speed, much like an engine, assuming 100% VE. Now we add boost to the equation and the adiabatic efficiency drops off. Of course cubic inches of the engine the "blower" is on, better heads and "better" camshaft, affect the boost if we have the same "blower" speed (Think about it a second folks, if the engine can pump as much as the "blowers" can feed it, we would have 0 boost). Whipples have the best adiabatic efficiency on the market when it comes to superchargers... almost as good as turbo's if everything works together. It takes hp to drive "blowers". It takes less hp to drive Whipple's in comparison to roots style. The internal "pressure ratio" of a screw compressor can be changed at casting time, or by porting of the housing. This is how you can tailor the adiabatic efficiency for the boost range you will be using.

I do agree that Pontiac heads would yeild a better environment for achieving the high horsepowers talked about in this thread. I do not agree it has much to do with the intake ports(other than a bit less boost therefore increasing the adiabatic efficiency of the "blowers") but more to do with cam timing and the obvious superior exhaust port the Pontiacs and others have(The overlap cycle is our friend in "blown" applications as it contains the key to cooling the surface temps of the piston and chamber, and of course maximizing fuel efficiency). Making the horsepower with "conventional" heads is definately possible. The dilemna might be in controlling the heat generated at that high hp level.

Heat is energy, energy is horsepower. But, you must be able to control the heat or destruction will follow.

Time will tell if we are to see the 5 litre "blower"

p.s.NOBODY, I don't care who you are. It's good to communicate with people of above average knowledge in this area. I'm not looking for business here either.

Nobody is somebody!

Can I guess
3042HP?????

if shinny paint and polished aluminum are all you need to see to buy something , i have got a deal for you.

i was never a customer nor will i ever be. i don't buy snake oil.
