just order a fp red . might get a e85 tune next week. Would 500 hp to the wheels possible guys. that is my goal.

 

ON e85 I dont see why not, with the right supporting mods.

 

Do you run the car at 29.5 psi daily.

 

hey guys, what is the max hp you can achieved with 93 pump gas with fp red and 272 cams. No others engine work accept for all the usual mods ., intake, exhuast, ect.

 

I'd say the max "safe" horsepower would be just above 400 whp, but a dynojet would throw out numbers closer to 450. Beyond that, you're starting to endanger (or at least minimize the lifespan of) the stock block.

My 2 cents, anyway.

 

+1

 

my mods are: hks catback, megan downpipe, o2 housing,test pipe, 1000cc pte,hks bov , upper and lower ic pipes, turbo xs intercooler, hallman pro mbc, koyo radiator, hks cold air intake,fp red 80mm. I really wanted about 500hp, would 93 pump ok, or e85 guys.

 

oh 1 more mods, brian crower 272 intake / exhuast cams

 

do i really gotta have head studs / , head gasket, for around 500hp.

 

Can't do that man.. If youre tuned for a certain psi you need to stick with it unless he changed your tune for something less potent for daily driving. Im sure he spent the time to get things perfect at 28 while at 26 you may be hitting cells that are actually more aggressive. Make sure he knows whats up so you dont put youself in a bad situation.

I do dual maps with different boost leaks and completely different fuel maps and timing maps because i found alot of my customers asking for a wicked pump tune then not running the boost i set them at. Most of the time its okay, but without logging every single boost you dont know what youre really getting.

Cheers!

 

I would run 28 psi just to be on the safe side. I had received bad gas on a few occasions and on 2 of my old cars kaboom......just my personal preference.

 

Thanks for the concern but I have my boost turned down but I only use about 10psi to get to work and home on a daily basis. Because I have the o2 dump I rarely go WOT on the street....too much trouble from the fuzz

 

The Electronic Fuel Ignition class that I took stressed thermal management, especially when it comes to forced induction engines.

It's the raised cylinder temps that are more the issue. There is a loose formula for offsetting every PSI you raise the induction pressure, unfortunately it escapes me at the moment and I don't have my class materials with me. When you consider some of the relatively cheap ways to guard against pre-detonation and knock, it seems a bit short sighted not to insure that you have off set the higher cylinder temps.

How many "charge cooling" mods have you done?

E-85 would be a big one, but you'll likely need double pumper, 1200cc+ injectors if you go through with it. (Edit, just saw your mods list)

I'm going to through this out for discussion, what about the Mishimoto Racing thermostat? Cooler block temps won't hurt. They are a cinch to pop in, only don't use any gasket goop. Just use the dry one that comes with it. I noticed 10 to 15 deg colder coolant temps when the engine is under load, at least according to the EvoScan logs.

(Edit, saw mods list etc...)

At 5800 ft, I figure that I'm around 475 HP / 460 trq (fluctuating with outside temps) FP Red running at about 29-30 with 272i/264e HKS (32 psi when I'm feeling gutsy), E85 with 1200cc's, double pumper, Nisei IC, and racing thermostat. Knock is very rare in my case, but so is the air up here, you might have concerns with SC's denser air.

These are all just thoughts. You might have already considered all this. A reputable local tuner's advice would probably be the best way to go about deciding just what you will need.

Hope it all goes well

 

There is no single answer to that question. It's not as if all cams labeled as having 272 degrees of advertised duration are at all alike. In one recent test, I recall a 50whp difference between two different '272 cams' in an otherwise identical setup. You'd be wise to read AMS' cam test before you follow through with your current plan.

FYI

 

Given similar mods, the same turbo, as well as the same fuel, then the same tuner should be able to safely tune for 1-2 more PSI on an Evo IX vs. an VIII.
