LS3 How to increase horsepower increasing redline other than exhaust..... ?

VetteVinnie

Heads, cam, porting, supercharger....

You can't increase redline without a custom tune, but all of the above would require custom tuning anyway. Exhaust system alone won't buy you much without the supporting modifications. To get more air out of the engine, you must first get more air into it.

All it takes is $$$

DrKrieger

how much power do you want? It totally depends on how much money you are willing to spend.

To be able to sustain 190 mph for 20 minutes duration. Take an hour break to cool off and then do it again for 20 min at 190 mph. Is that even possible without breaking down. The limiter here is that its a wet sump engine. Can that be changed out or no.

How and why would you even sustain 190mph for 20 min straight?
there is not enough road for such a thing to even be possible

Couple things come to mind...190 mph for 20 min is 63 miles PLUS getting up to 190, and back down, adds several more miles so you're looking at 75-80 miles of asphalt.
As for the car you're going to need a lot more than a dry sump. Try twin turbos/blower, cam, exhaust, more cubes, etc...and plenty of laughing gas...which I think this whole exercise is about.

PMPerformance

I think the main takeaway is that there is no realm of possibility you are getting enough road to sustain that speed anyway making the conversation moot.

But to sustain any speeds in the triple digits for any period of time will involve a WELL built motor and even then, there is a short time it will be able to take that kind of abuse of even possible.
Heat kills parts! High speeds for extended periods of time= stupid high EGT’s which will surely melt things quick.
Ask anyone that does 1/2-1 mile events or regularly roll races.

Interesting. What one wants to do and what one can do are two different things. I can dream I guess.

PMPerformance

in the nicest way I can possibly put this, you are pipe dreaming my friend.

KLHughes

Lol

Do you think it possible to run 180 mph for about 12 minutes and the remains 8 minutes at 155 mph?

ruxvette

You need a hobby.

PMPerformance

Please explain the background of these questions to give us some scope of understanding if you are actually trying to accomplish a goal, or you are bored and just asking nonsensical theoretical questions online?

I think you guys are just feeding the troll at this point lol... 6 posts and mostly nonsense

VetteVinnie

And this is the most activity in six years of forum membership. I vote for drunken boredom. Been there.

Even Bonneville is only 12 miles. Canonball run, perhaps?

I stand by my above post... the biggest turbo money can buy... stock motor... send it bud

Open road racing......
