Which one? ... Mr. F-16 attack Man :P

No .. I don't know what signifies a flat torque curve. 5+ Years of engineering school, and purchasing and riding V-Twin bikes does not mean I know, nor feel a single thing about a flat torque curve. (Now let's assume, that 'you'll' ***-u-me that I drive a Hardley.)

Take that tongue in cheek. What that really means is you can approach me with very technical details, but yet I require that you be very precise and consistent in your technical word choice and usage.

Example with emphasis: The "amount" = quantity of "power" remains "constant" ... and that means "linear?" ... oookkkk ... "constant" is "one case" of "linear." I believe I know what you're saying, but it seems we both need to be more clear in our arguments.

I don't doubt the effenciency of a turbine. How to get the turbine into its effenciency range is a challenge that 'all' "reciprocating piston heat engine" afficionatos relate to. In some cases, having a "less efficient" method of compressing air for an engine is the "best" engineering solution. We both probably agree that the whole drivability of an automobile is greater than the ONE variable, called the effeciency of a compressor. As far as the twin screw argument ... Whipple < Eaton < Twin Screw < Turbine < 100% efficiency.

Again ... I would really like to hear some of the forced induction ideas from Mike.

I've asked for MSM's input from the get-go, yet have only recieved your hashed out responses.

This IS his automobile we're referring to ... and FWIW ... because its such a high-revver, my interest is peaked to see how the hi-revving Hondas really perform.

FWIW, I have a pretty good adquantance here that drives a 12,000rpm balanced B18C5 built Integra GSR. He put on a Jackson Racing (Eaton) 10psi supercharger, and runs the thing with just over 10:1 compression. He's rpm limited himself to 10k rpm, but for street drivability, he absolutely smokes my EVO. Usuable boost, (where you feel the motor really come alive) comes on at 1500rpm, and effectively signs off at 8000rpm.

Please. At least we both can make less "***"+"u"+"me"+umptions if we're both on the same page.

Cheers,

jcnel.

P.S. oh ... i just had some time to think about effeciency in general ... as in the engine world, if you hold the rpm as constant as possible, you can push effeciency waaaay up. This is one of the reasons we run wastegates on our turbos. If the rpm is above or below the optimum, we don't want that.

On jet engines ... they always are running between 80% and 100% of their rpm range ... why? ... they build power only at a very narrow rpm range.

Hehe .. don't think I'll delve into "electronics" effeciency, but the concepts hold true there too. It probably enough for you to know that I am required to build in "slop" into my electronic designs because its the best solution.

On a supercharger ... the idea has been to sacrifice some of the constant rpm effeciency for a broader boost characteristic. Its a tradeoff ... personally ... I'm glad the supercharger boost boys have some way to get away from the whipple design.

 

i would love to look @ your friends dyno chart (integra kid) saying he whoops your evo probably isn't saying a whole lot.

 

About all I can add is to say that I like the very smooth power delivery of the supercharger. There are NO bursts in acceleration as boost or vtec come on. It's smooth, consistent and predictable all the way to 9000 RPM. Some 1/4 mile focused straight line S2K guys have had good success with turbo setups. Why anyone would focus on 1/4 mile with S2K is a WHOLE nother question.

I've driven a couple of turbo-charged S2000. Didn't like either of them. One ride in a supercharged S and I was sold.

As to efficiency? I have no fv'ck'n clue. Where does the car spend 85 to 90% of it's time on the track? ... btwn about 6,500 and 9,000.

 

Get em before the hair does

Mike you need to buy this!!!!!!!!!


Then your car would be so sexy i would **** myself.


Now with all this arguing I need to put my 2 cents in

[technical jargon]Superchargers lick my *****!![/technical jargon]

Ben

 

bwwwwwwahahhaahaha!!!!!!!!!!!!!!!!!!!!!!!!!!

 

 

'zat you Ray?
That body kit does look cool (if that's what you're talking about Ben) but he needs a wing too

 

Does anyone know who owns the Silver Evo that was out to RMR on friday night. He got a 12.2!!! That is awesome. Just curious what mods he has done????

 

That would be silverofs. I think he ran a 12.4 @ 112. He has LOTS of mods!

 

The silver one was Zach. He ran a 12.4..............He wishes he ran a 12.2.

Were you the guy with the black one in the parking lot?

 

Oh, my bad 12.4. But that is still awesome. Does he still have the stock clutch? No I have a Silver Evo. Mine was home in the garge. I rode with my buddy in the Silver STI.

 

No stock clutch.

 

Wow, that's amazing. With all the bad rumors I have heard about the clutch I am amazed it holds up when launching the car that hard.

 

He meant..............no, he doesn't have a stock clutch.


Zach where are you so you can answer ?

 

Evodude8, what part of Utah are you from?
