how fast are header equipped gle's?
 

lets say an otherwise stock 2k2+ auto is equipped with hotshot or cattman headers. can they pull on stock 6spd 2k2's? and by how much?

hmmm, that would be an interesting race. I think the auto may win. The drivetrain loss i dont think is greater than the gains from cattman headers on the 3.5 engine. Isnt that like a 20-25 @ the wheels gain? and normally arent the transfer of power from the crank to the wheels normally a 20 hp loss? (i remember the 4th gens having 190 hp and people putting out 176 or so stock?). Plus the power under the curve may be better wit the header setup....Interesting race nonetheless....

from a dig...the auto will have a chance of winning....that is if the 6spd messes up...it's very tricky to launch a 6spd too...but from a roll...the 6spd should still pull away....depends on wut kind of roll too....if it's 65 and above....the advantage is more towards the 6spd.....cuz right when the auto tranny hits 3rd gear....its a very loooong gear while the 6spd is still holding 3rd all the way to 92-93ish mph

Are those Cattman's really pulling 20-25hp more. It seems possible because the hotshots are showing 19hp (I think someone dyno'd them on the org)? Good question about who'd win. That would be a close one....

Easy answer! The 6 speed with the headers :laugh:

in a 1/4 race, i'd put my $$ on the auto. anything from a roll tho, the 6 speed has a better chance cause of the close gear ratios. but both are quick :)

and the word isnt "fast" (top speed) the word is "quick" (amount of time to get there)
very diffirent

and i would win :thumbsup:

Not if I were there... :hide:

we have the same car!

Almost the same... :naughty:

you always have to bring up the fact that you have HLSD unlike most people, huh?? :attention :D

puppet master has HLSD!?!?!

it still won't make his car quicker in a straight line.

yup...(i hope that wasnt a joke, cuz i took it seriously :bonk: )

i thought that it would make it a bit quicker, simply because the power to the ground would be managed a bit better than a non-HLSD max...

I heard two different stories....

1. Our maximas have so much TQ that the HLSD WILL NOT help wheel hop in a straight line race....it will only help our car's if it's exiting a corner

2. HLSD does help our cars in a straight line race becuz the power would be managed just like maxilvr06 said.....

can any body clear & confirm these scenarios?

Solid motor mounts kill wheel hop, not HLSD. It's good for curves, but doesn't really have an effect for straight lines...

No it won't, I never said it would... I was kidding around with Jason (Soonerfan)... sorry to cause any confusion... :grinno:

i went to a track and i had a run with a 6spd max 03, i have a 03 auto , both had EVERYTHING STOCK we did a run from 20 mph up till 100 we stayed neck to neck the entire way we did 5 runs out of the 5 runs he once got about 1/4 of a car on me, and that was when i took it up to 120.

This was a secured area where we had these runs.

yeah, when i said that i wasn't exactly expecting it to turn into an HLSD debate, but i was just commenting about how you said you and sooner's cars were almost the same, which to me, implied how you had HLSD and he didn't :thumbsup:
and don't get me wrong, if i had HLSD, i would be bragging about it to regular 6-spd owners as well :wall:

You didn't say anything, i wasn't putting words in your mouth ; ).

I was just saying, that's all. I threw an HLSD on my car remember?
Definatley makes the car more reliable in lousy weather, and when you wanna have fun around the twisties.

the stick better pull quick on the line... cause high end auto and stick are pretty much the same...i think auto would take

I agree... you can feel the HLSD help in the wet or snow... and even when gunning it around or out of corners, but that leads me to believe that it would at least help when you're launching, since like already mentioned above by Steven and Maxilvr06, the power to the ground is "managed" by the HLSD. The only time I think I've "felt" the HLSD work is when I've taken a corner in wet conditions and tried gunning it when I'm halfway out of the curve... the inner wheel feels as if its slipping but then the car still straightens out nicely when the outer wheel starts to pull more.

From my understanding, the HLSD works by shifting some power to the wheel with more traction while still supplying a little to the other wheel. An open differential transfers the power to the wheel with least traction (path of least resistance). Thus, if the car had HLSD, power would be distributed more evenly between the 2 front wheels leading to more traction on launches (assuming no/negligible wheel hop). That's why if ya took a car with HLSD and dumped the clutch at say 3000, you would almost always see twins left behind (I've tried this a couple times, its true). :gotme: I'm not pretending to know a lot about this, but just based on my understanding, it seems that with HLSD, launching would be better, so all comments/criticisms are welcome.

And yeah, wheel hop is only reduced by reduced flexing of the motor mounts and maybe the suspension bushings, not HLSD. Wheel hop is not the same as traction.



PS: I have HLSD. :ben:

exactly what i was thinking....that's why it would make more sense that an HLSD-equipped car would, in fact be better off the line...i think that most of these people are referring to a race from a roll, which really wouldnt matter whether you had HLSD or not, because the traction is pretty much already there, unlike from a stop...(if that made sense at all!)

not fair.... :mecry:

For those of you interested, I stumbled across another thread debating the effectiveness of LSD on launches (given that this was in the FI forum, so they're talkin waaay more hp to the ground than we are)... their opinion is that it doesn't help much...

so it looks like we have the same car after all when it comes to a straight line race.
and i would take you now since i have MT-90 and you dont :D
