why not just get a race gas tune?

 

a fp-grn with a strong tune should get you close to 400 on 91 while using the oem maf.

what w/g actuator will you be using?

ditch the mbc & go ebc / ecu boost control via gm 3port as well.

may want to look into a good airbox too. a open air filter will hurt your power during the summer months.

HOT engine compartment air reduces power quick.

what boost levels were you running to get you the 360 dj whp?

 

400WHP with 91 Octane without Methanol is Impossible!
I have seen +400WHP Evoz on "OEM Evo IX Turbo" with Methanol.
You can Use E85 if you don't want to install Meth.!?
26-29 PSI and a good Tune will do the job on both setups!
Just remember to ask your self this:
Are you on your stock block? what FMIC will you use?
Good luck

 

not true, as i made over 400 dyno jet WHP on several occasions, all while using california's 91 octane with different mods too.

my latest dyno was 415.x It's making even more now

look @ the dyno chart below for my cosi M2 vs GSC S1 cam compare.

 

I think he meant it was impossible with the stock turbo. I definitely believe a green pulled this numbers.

 

This is from the OP& it's within my quote that he used as well.Yeah, on the stcok e9 turbo that would be very difficult.

 

FP GREEN + METH= 400 + HP (if tuned well)

 

Aby good numbers, which actuator did you use? Was that with the 100 cell cat?

 

I always liked race gas better..MUCH SAFER imo.

 

^ And more expensive

 

oem & test pipe.

i have a fp w/g actuator now...it eliminated the strange boost fluctuations after reaching the desired boost target between 3,700-4,400

 

if u want something safe i'd say go for E85 as long as its readily available in your area. that way you could increase the boost to achieve your power goals. you could put in meth but dont rely too much on it. make use of it as a safety net .

 

yeah it doent take much to hit 400whp in an evo and for "khara" i said 880 cause its a lot smaller then 1000 and for one it doesnt matter as long as they're not monsterous injectors it all matters on the duty cycle and a tune so you should prolly look into your research a lil bit more

 

Thats true.
It seems he did not read that i +400 on a stock IX turbo!
Aby@MIL.SPEC forgot that the post is about 91 octane and 400WHP.

 

False.

Ideal spray on an injector is 85% duty cycle. The fuel atomizes very well and the injector isn't going static.

If you use an injector WAY too big for your application, and your duty cycle is under 60%, then you are "globbing" fuel and not atomizing it... Performance suffers as a result.

You should always look for the injector that will peak at 85-90% duty cycle. No more, no less.
