I'm in an argument with some Honda boys, I need a dyno with just rediculous numbers. So who's the big man around here?

Hust tell them there is a video with a guy putting 1011 rwhp. The video is in the ls1tech video site, probably under camaro. I just saw Tuesday night. The guy had a twin turbo 35th SS.

the ohio boys maxed out the same dyno at 1200rwhp i believe?

show them parish's TRUCK
its somewhere near 1khp now if not more
and well over 1k tq....

biggest street car dyno numbers i know of is the white chicago marko supra. 1200+ with teh ohio boys is pretty badass too.

Maxing out the dyno would be nice

Let's stick this to LSX series though!

Yeah, Marko did 1520 RWHP through a turbo 400 and a really loose converter, a little over 1900 at the crank; I wouldn't call him a dyno queen though as he runs mid to low eights at around 1200 rwhp on his street tune.

I doubt he's losing 380 HP through the driveline

Awesome numbers nonetheless!

SleeperSupra

At 20% drive train loss due to a loose converter and turbo 400 tranny this equates to roughly 1900 HP at the crank.

I think your main issue is that you are arguing with some Honda boys. Tell them in a very sarcastic manor, "I love Hondas, even thought about selling my car a time or two to get one". Then walk away. Kinda like arguing my grandma about politics or religion, I just stopped doing it.

When they tell you it is a 20% that may be 20% on a stock car. It doesnt take any more horsepower to turn the th400 with a 1900hp car or a 300hp car. So a 1500rwhp car is proably like 1550hp car. (not sure how much there is lost...)

Yes it does take more horsepower to turn the TH400 with a 1900hp car vs a 300hp car. Its based of percentage, so 20% of 300hp is 60hp, 20% of 1900hp is 380hp. Simple math there sport.

20% is 20% be it on 300 or 3000
not 20% on a stock car only...

So you donkies are telling me that the th400 gets heavier (which is the largest part of your loss, the heavier parts)as you add power? I dont think so! The converter might slip a percentage but if it is 20% then you need a new converter. The trans and converter dont change weight or diameter so how would it take more power away from the car as you add more power?

For instance... 20% of a 300hp would equal a 60hp loss (which means it takes 60 hp to turn the heavier parts of the drivetrain) These parts don't get heavier SO there is no possible way that the same car could eat up 20% of a 1000hp car (which all of a sudden it takes 200hp to turn these parts?). There would be a set amount of power that is lost (lets say 40 due to heavy parts) and the other 20 hp is lost due to converter slipage.

20% drivetrain loss is 20% drive train loss. Be it 300 or 1500.

Lets say your stock motor made 400fwhp, and your new Tinsihed/Overton setup makes 600 (just for comparison sake)

You lost 20% of 400 getting to the ground, thats what 80rwhp? makeing aound 320 touchin the pavement.
Your new setup makeing "600" will loose 20% due to drivetrain loss too, thats what 125rwhp. there for you put 475ish to the pavement.
(not taking into account for your new tranny/12bolt)

Drivetrain loss is a basic percentage that doesnt change. Its not a set amount of base horsepower that you loose, its a percentage of overall flywheel (motor only) power that you loose.

I didn't want to get into this debate but you're deadly wrong. Think about starting a lawnmower. It only takes so much energy to overcome the friction of turning over the motor to turn potential energy into kinetic energy. A guy who can rip the legs off a bull is going to have to work harder to start than me(is what you're saying)? I dont think so


Parasitic losses from friction are just that. Parasitic losses. To turn the same peripheral drivetrain equipment at the same rpm will take the same amount of energy regardless of if you're stock motor, turbo'd or anything else that matter. You're wrong plain and simple.

Id have to agree with you there Brandon , its a rough estimate 20% auto ,
15% standard shift type, and no the parts dont get heavier ( LOL ) its a ESTIMATE that has been proven over many years , you will loose more or less considering you combo ..
just my .02

call any shop that builds fast cars, and they will tell you the same
call W2W, Mike Moran, Hardcore, Eastside, HPE, etc, (just a few of the guys that are in the "big" game right now with their cars) You think that the Ronnie Duke 7sec F2R charged t/a isnt loosing somewhere near 20%?

hahaha, seriously its laughable. If that car has a t400/9" (once again for comparison sake, im thinking its a glide/fabed 9" however) and you think it will only loose the same amount of HP as a stock motored car would with the same drivetrain setup, you sir, are wrong.

I'm sure any of the big guys, would love to just loose that 60-80hp that a stock motored car would loose... That would be awesome.
