What do you all think? The only thing there to help fuel delivery is a Walbro 255lph HP, and a Haltech E6K.



Do you all think its possible? ( nevermind all the "is it efficient" b.s. )

Stock fuel system is maxxed at 11psi...

11psi?





I think its safe to assume youve never had your car past 11psi, eh?

Haltech or no haltech..the 550cc injectors will fail at fullfilling a 19psi pull...unless the duty cycle is maxed and it creeps to 19psi, but not a steady 19psi.



Stock IC handles 10psi "OK" but I wouldnt be shocked to see it fall apart, per say, at 19psi....the rubber IC lines probably wont even hold.



Stock APEX seals take 22psi with the best tuning.



that fuel pump helps, but 19psi takes more then standalone and upgraded fuel pump...



Basically, my answer is NO! lol..



BTW, I have driven/worked on rx7s boosting more then 19psi if you wondering if i have experience with this...

Another quick note...



then stock fuel system will go past 11psi as long as its a creep, but you cant pound more then 11psi through 1st, 2nd or 3rd, etc...



normally a TII w/ open exhaust will creep up to 13-15psi on stock fuel system(ask ILUV88 and his AE,lol)...



also, my buddy's '87TII(roadkill669 on the forum) goes up to 14psi regularly if you floor it in 5th...



Of course, I noticed that in ur list of mods...no turbo is mentioned, the stock H18 will def not make 19psi,lol...

Yea you can run more than 11psi, but you'll go lean fast.



I have drove a t2 at 15psi, with just a fuel pump.. Guess what? It blew a week later....



If you think im full of ****, go ahead run 19psi on basically stock fuel system, LOL

Hmmm...Just as I thought.









The funny thing about all this is that last night I was running 19psi for the entirety of the night ( I tightned my boost controller too much ). It didnt creep. It just smacked right up to 19psi and held through all gears. Pulled VERY hard too.



Kinda makes me wonder where you all are getting all youre information...Is it all just second hand stuff? Has anyone here in this thread ( aside from me ) actually tried 19psi? Or even 15psi? I run my car at 15psi daily with no problems on stock injectors/IC.

My car has ran at 15psi for a good while and its still running strong.





And I did run 19psi. It felt really nice. I wanted to do it some more but thought better of it.
