That's why I won't be trying that first. not for a few whp.

 

With what I know about yourself, the way you are using your car and the turbo options out there...then sprinkle in budget due to an unexpected turbo going by-bye...I am sure you will be happy.

Like Markski said a tight car and proper tune are key. I know you are on the right track there as well.

 

The good thing about my situation is that i have a 2.54 mile dyno named Road Atlanta 15 minutes from my house. My data has updates every 2 second on my position relative to my fastest laps. I know immediately if Im faster on corner exit and on a straight if Im pulling ahead or not.

At the very least ill have more definitive answers on what works better on track and in what areas.

 

Dez, What do you use for data logging?

 

Traqmate with dash.

 

Assuming your cores are good, why not rebuild your K24s into a billet hybrid? Maybe what SamboTT@ByDesign is already suggesting, IDK.

 

per trackheavys goals, gotta plus 1 on the sambo's 16/24 hybrids. while not "billet" they are monsters for bang for the buck and provide near instant spool.

i'm a about 550 rwhp with them, and the usal supporting bolt ons. love em.

 

That actually sounds perfect. Do you have a dyno, or have you seen any posted here?

 

Car is astonishingly fast given all parts are simple bolt ons. As to dyno specs etc. I dont have but hit up Sam here.he knows them very well and they came from him.

 

Sam likes a 16/16 based Turbo for my application. So we are going to try that first. I did inquire on the 16/24 though.

 

My experience has only been with an x50 k24 and them my current 16/24,setup. Sam knows so I'd go with what he suggests ultimately. He's never steered me wrong.

 

K16 billetes are the way to go for a track guy period. Injectors , iCs and exhaust along with a good tune.

Are the injectors required? What about a 5 bar FPR too?

 

injectors give you much better injector/duty cycle margins. I did injectors just to have a safer set up...

 

Yeah, I'm sure those would work. But the OP mentioned that he lives over 4500 rpm on track and doesn't find his stock K24s objectionable for laggy response in his on-track driving. So I still think a rebuilt K24 with a higher flowing billet compressor wheel would be a good option for his specific situation (plus injectors and a track focused retune).

Heavy, who's tune are you running now? Will you keep that tuner or looking to change?
