I'll agree and disagree. RPM is A controlling factor. No RPM, no boost. Using your example a little bit closer to earth, large bore engines such as used on tractors, some trucks, crawlers, etc. are turboed in some applications. Sometimes the engines might turn a max of 1000 RPM, so it is all relative. They create the boost because, with the bore size what they are, huge amounts of air is moved through the engine in one stroke. And this is a case where extra load will create extra boost. The engines are running at a constant RPM but put the crawler behind a big pile of dirt and you see the black fumes emanate from the exhaust pipe. You can hear the extra load spinning the turbos more. But that doesn't necessarily apply to trucks or cars.
Load can be achieved by going to WOT and the force needed to move the vehicle is the load. My point has been that with something like the H2, you are at it's threshold by trying to just move the truck and there is not enough engine left to create more boost upon adding additional load from a trailer. It's all about application.
Jonahs, I think I agree with what I think you are saying. I just thought the comment about RPMs wasn't entirely true. A turbo CAN be created that has boost earlier in RPMs thereby increasing torque and with proper control and wastegates handle the top side of RPMs and "overboost".

Not in disagreement at all Paragon. We both know you can't generate boost at idle. I was only making the point that boost can be generated at low rpm-high power settings. I really think we're all in agreement. And that's the advantage of turbocharging. Flexibility. Many think you have to wait for very high rpm before you can generate boost and that's not correct. In simplistic terms, it's all a matter of suck & blow.

I knew what you were saying but for the benefit of someone that comes along and focuses on that one point..... well it was a pre-emptive strike.

I thought I would mention this. I'm working on a SC deal but I'm also working with 2 different turbo co.'s on turbo ideas. Both seem very sharp and We are in the discussion and design stage. If I can not get SC deal then I'm working on the turbo idea. We are working on mapping the turbo to spool up quicker and at lower RPM as I do not want a stall speed converter and I want power sooner than 3000 rpm. Both are looking at how linear they can get turbo power to come on than just at 3000 rpm it kicks in and burns the tires off. I have explained once I get to 3000 rpm with the after market add ons the Girl runs quite well. I'm very disappointed at take off and hard to get her rolling. Spoke with one of the turbo guys this afternoon and he is going to a custom turbo build guy and have discussion. We are also discussng a twin turbo set up with small turbo's and sharp impeller twist to allow for quick low end spool up. We are also looking at twin turbo's where one turbo is designed with more low rpm spool and the second to spool up at say 3000 rpm. A chain reaction type set up where the first does one job and the second does a different job by kicking in at higher rpm. He has a computer program where he loads spec in and gives Him idea of what theoreticlly could be tried. I told Him if I have option of 500 Hp at wheels and 400 ft. pds. torque or 400 Hp and 500 ft. of torque I want the 500 ft. of torque as that will get H2 of line quicker. If I'm wroung here i need to know so please add Your 2 cents worth on this. This is a very serious topic with Me and I know there is a wealth of knowledge here to help Me get in this design what is actually needed.
I hope to have SC or turbo on by end of March or early April.
I would like opinion of heads up race with identical H2's in a 1/4 mile who will win TURBO or Magna Charger?
Everyone please share with me Your experience and knowledge of this topic. It very well may be incorporated into these designs. So serious knowledge and help is required as soon as possible. If I can get something designed then others would be available to try this out once We have used me for test.
Thanks Guys and help Me out here so it does not require to much longer to get this done. If You want Your comments private that is fine PM Me. I would really like everyone inputting on this. If We do something very different and it is not a patented idea I have already decided to do so and would be happy to include anyone that puts in ideas that gets used in this unique design. Seriouly We could have a patent for H2Source that We all benefit from by selling kits etc., we will just reimburse Me for the expense i incured developing it. If You are interested in being involved in a patent type situation if your idea is helpful in R@D PM Me so I can begin a list recorded and the idea You submit on the PM section so it can be saved by You and Me. It will cut down on disputes of who suggested what and at what date and time as it will be recorded by both of us in PM's. We can also display ideas in open forum to spur more ideas and keep open record of who suggested what if We patent. some of You have gotten to know Me better than others. I'm not a selfish person and anytime I can Bless others even in finances I always try to do it. I could keep this quite and do it Myself with the help I have inlisted but I would just like to do something for all You guys and gals that have welcomed Me unjudgementally and with all My quirks like writing novels. I hope to overcome that but the least I could is bring a financial blessing to you and Your family.
Thanks and let's get going on this. bring up in forum and then PPM me so that Your idea is double recorded to prevent disputes.

Notice the two stage turbos are used on diesels.
BTW, here is your answer. Go with the SC or single turbo setup. Then add a small 50-100 hp shot of this (I know I want to): http://www.holley.com/HiOctn/ProdLin...NOSNS/GM2.html (That may not be the exact part number)

I called Kenne Bell a few weeks ago and they are working on a NEW supercharger for the 2005's. It will be intercooled and have some really good power. They say it will be available in the next few months...

Good Job Ken. You have covered everything The Guys and I have been discussing for a month as well as some testing. You are as sharp I as thought You were. We have checked around and so far have not found anyone doing what I'm asking to be done in a gas burner. Not that it is not done We can not find it unless it is someone out in thier garage with one right now.
There is still a twist that i won,t reveal but in PM with those that want to help with ideas or let me bounce ideas of You. We are farther along than one would imagine. It could be done and installed by the next bigger show late in April or last week in March. If I do not end up delaying it with hospital trip. I informed them today i have a problem but keep going.
