Whats your point? That discussion was about the speed limiter, this disscussion is about the rev limiter. 2 completely different things.

Im sorry if what I said came across that way. I was really frustrated today and hopped on here trying to get my mind on another subject. I was mostly wanting to attempt a theory I had and was hoping that someone would know of an easy way to raise the rev limiter that wouldnt cost very much because Im broke as s### right now. I just spent a ton of $ on other areas of the car which is kind of why Im trying to keep this as hush, hush as I possibly can. Once its all done Im going show everything in one thread. I will tell you that the turbo is a ct26 and my manifold is the most hideous thing anyone will ever see, but it works. The turbo was given me for free btw and I posted a thread asking what to do about the manifold which I eventually fabricated a working one.

The TSX that this guy has is the brand new one with the 3.5l V6, but it also dawned on me earlier today that up until yesterday my intake has been swimming in ATF because this happened https://www.clublexus.com/forums/per...s-one-out.html
To blow off some steam earlier today (because of a stupid girl not CL) I pulled apart my entire throttle body, cleaned the **** out of it and went for a drive and I think my sh##y mutant manifold is starting to fail, which is probably whats causing me to lose boost, but I still think 2nd gear is too tall and I would love to test my theory of raising the rev limiter to 7000 or 7500 rpm. I know doing a 5spd swap would be more ideal for what Im trying to accomplish but Ive been having a hard time finding a decent r154 or even w58 and like I said, I just blew way to much $ on other areas of the car but youll all have to wait 1 more week before you get to see it.

Dude if you want info on sc300 or 400 in colorado find FrankDMS. or go to the www.triplecrowndrift.com site. i think his email is frank@denvermotorsports.com

PS quit you BS crying stuff. and if your getting beat by a TSX something must be jacked up

I have been in this section of the forum for 4 days and I call total 100% BS. There are too many inconsistencies in this story.

You obviously missed my point. My point is that your statements make you sound like you're full of ****.

what size turbo are u running? big? little? single? twin? remote single?? i wanna know how big this turbo is that cant be spooled up fast enough by a v8

why would a v8 spool the turbo faster than say a v6?

Im not questioning your logic or being sarcastic I just really dont know alot about turbos and I like to learn wherever I can.

And im also assuming the bigger the turbo the longer it takes to spool?

Spooling=the turbo giving power to the engine?

Thanks in advance

We'll he's going with the generality that v8s are typically larger displacement which tends to hold true, as v8 under 4.0 liters are fairly uncommon and 6 cylinder engines over 4.0 liters are uncommon as well

With that out of the way, quick and dirty physics lesson for you

Force = Mass * Acceleration.

So with that in mind, if the acceleration of an object stays constant but it's mass increases, force will increase right?

A 3.0 i6 will move less mass of exhaust vs a 4.0 v8 at the same given RPMs, therefore the exhaust coming out of the 4.0 will have a greater force on the exhaust wheel of the turbo.

Now we go back to the initial formula, As the force on the exhaust wheel increases and mass stays the same, acceleration will increase. And we now have our faster spool time

thanks for explaining thaqt .

to show you how limited my knowledge of turbos are, I didnt realize till now that they are powered by the exhaust of the car its attached to.

Either no turbo or one of the coil packs is unplugged...or something. My W58'ed '93 ran mid to high 14's (time-slip verified) at sea level with everything else stock and an unplugged maf because my ecu was old and probably had half leaking capacitors or something.

Regardless, if you really were boosted you should go standalone and for under $600 you can build your own Megasquirt 3/X and install it. You would also need a wide-band which you should already have if boosted anyways. I got mine dialed in better than the factory tune [in most areas] within a week.

I would love to see a dyno of a stock 1uz revving to 9k lol. It would be a perfect parabola!

Maybe he meant the Turbonator lol

now that might make sense lol.... haha hey matt how much boost are you running exactly?
