Are standard K24s capable of about 500 whp with the right supporting mods and tuning? Thanks!

 

HI,Yes they are..No problem..Rear wheel..
I did it with my first Mods of a GIAC tune and Cargraphics exhaust...So have many others with a good tune and a good exhaust..

 

Yes, I believe so...

the recipe goes something like... free-flowing exhaust, upgraded 1.0 bar WGs, fueling support, good ICs and tuning should get there, +/- a bit.

However, if you don't already have one, you'll probably need an upgraded clutch too, to be safe, and if you're doing that, might as well do inlet piping "while you're in there," etc.

And, at that point, you've addressed the major areas needed for a rebuilt hybrid turbo K24 billet upgrade (18g or 20g or ???), or a turbo swap, to yield an even better result... which is why I think the seasoned guys say, "it's a slippery slope..."

 

k24, 1.0-1.1 bar FVD tune, small cargraphic exhaust only i made 516rwhp on 93. on stock wastegates, stock clutch, RWD on DYnojet. also inlet pipes didnt add any power at that level

After I did my 18g swap with my Cargrsphics exhaust ,then I put the inlet pipes on after that swap...They didn't help at all either?..Night and day difference in power/spool when I went to the Millek exhaust though.

 

Thank you prodigymb, that's very helpful as a solid reference.

 

And I am not a solid reference?...LOL

 

I should have used the damn multi-quote! You're solid too!

 

Thanks Buddy,now I will stop pouting because I thought I got caught BSing here..LOL...

 

Are you talking REAL hp or "tuner HP" ?

For REAL HP it's a huge struggle, K24 doesn't have the flow needed. You need to go from 475 OEM crank to a at least 560 OEM crank to surpass 500 true wheel hp. Exhaust, LWFW, fuel pressure, max boost, intercoolers, seriously dangerous ignition timing, will barely squeeze you to 540-550 REAL crank hp with K24 (as in >85hp gain from an OEM 996 GT2).

Maybe with meth or E85 and big injectors to cool the hot side you could force it over the true 500 whp limit but it's so much work, so if you don't want to be scared to blow the engine up every time you step on it, go for a turbo that can give a lot more airflow.

 

I agree.

-tune
-exhaust
-intake piping
-intercoolers
-waste gates ?
-lwfw

You are talking about 470ish.

That extra 30whp, will have to be 16g billets. Is it worth it 3.5k in parts plus labor for the extra 30-50awhp ?

 

You guys might want to do a search and see how many members have hit 500 REAR WHEEL HP on K24 with tune and exhaust.

 

18gs with open exhaust.. oEM wgs at 1.1 bar 525rwhp on a dynojet

 

Been here long enough to know a ton of people went over 500... tuner whp.

I even went 495 tuner whp with K16 turbos and exhaust once, just really aggressive timing and 1.0 bar boost. But real HP was just a 58 hp gain over OEM K16 (415 crank + 58 = 473hp crank). The dyno said 493 wheel hp though.

So, anyone looking for power needs to decide if they want a cool sounding tuner fantasy hp number, or a specific gain vs the OEM crank hp reference.

 

HI,,What do you mean by tuner whp?..I dont understand that term tied in with the Dyno numbers?
I have been on many dynos during my stages and have seen many dyno runs..I have been around for a while also But yet this is something I have not heard before in terms of output.
I have my dyno sheets from the Porsche Exchange where I did it and I also did back to back tests there on a product..
