wha twould i need to get 300+whp wiht the 91 octane tune...im getting the hks rs intake, hks dp, hks-hi power...what else?

 

Basically what I have I would guess. You could do it without cams, but they are so much fun!!

 

you can get 300whp+ on 91oct if you get rid of that HKS crap

 

what would i need? id like to have that hks hi power though

 

how much powe are you making without the cams? and do i need the MBC becuase wont the flash hold it at 19 anyways?

 

Arp head studs are always a good idea, along with Walbro 255, and a form of boost control set @ 20-21 psi. That should get you pretty close. With a dyno flash from Al.

 

can Al tune it to 20 psi or is the mbc required? what kind of inkake and dp should i use? i dont want to have to modify anything for them to fit without problems

 

my profile

 

I have VISHNU stage 1 and I got 298WHP avg on three runs. I think you should get close to 300WHP with custom tune You will need a fuel pump and run catless. There are several EVO's in Socal that are close to 300WHP. What is more important is the curve than the max power.

298WHP/298TQ for three runs with custom tune

 

what psi were you runing to hit 290whp?

 

23 tapering to 18 at redline

 

impressive number! woud you go for the stage2 in future ? if you will, what kind of cam combo do you prefer ?

 

23psi with 91 octane? wow, I thought it was too dangerous to go over 21 psi with 91 octane

 

23PSI is at 3500RPM's once it is over 4K the RPM goes down to 21. 23PSI at redline would be bad but at redline it is around 18PSI . With MBC and Dynoflash most people I know are running 19-20PSI with out taper while my tune was designed to taper.

 

I am done with engine mods since 300WHP was my goal. I made an additional 23WHP on 100octane gas. I think I have strong car since I made around 15WHP less than some cars with same mods plus cams&hotside
