Same stretch by the swamp.

 

Question: is the tq I'm making here going to be problematic for my bottom end? Running 20-50 amsoil with 100k on the block . My plan is to tune for big spike, switch to ecu boost, and taper boost to 20 by redline . Slightly lower than what the mbc allows

 

personally i would leave it below 400 ft/lbs. the initial big hit is the issue, especially when this is spooling like stock.

 

two overlayed, i think that this turbo can push a fair amount of boost in the midrange. Id like to use my IAT sensor to log some runs and see how bad its heating the air @ extreme boost pressures.

is that a good gain for the 4.5-5 psi push in the midrange?

 

id say so, works out the old rule of 10ft/lbs per psi just about.

i still think you've got a lazy waste gate and/or leaky BOV tho.

 

ya the spool is laggier then a green but at the same time its not really a bad thing in his case being on stock bottom end.

i still see the afr not leaned yet.. you lazy bastard.

 

lol, my logger is .2-.3 richer than my serial display. WOT my display reads 11.2ish, sometimes higher, I have to adjust my EVAL in evo scan every so often , of which I do not understand with the AEM WBo2, its supposed to be smart?

yes Im lazy!because i hear I could run 11.5 or better with no issues. I am about to put the car away soon, ill lean it out before i hit STM's mustang.


killer, I am counting on having this greddy type s sooner than later. The RFL does function mostly better than a stock evo 9 crushed, except for one thing which is some wild compressor surge rarely. Other than that, I DEFINITELY suspect the RFL from leaking at these elevated boost levels.\

PS: 18psi actuator will be here friday. pray for sunshine and dry roads, i will retune fueling entirely due to much needed closed loop changes.

 

sorry if this has been mentioned, stock cams still right? interesting thread

 

As per op, hks 272's

 

its raining here in PA.. if not yet there you're gonna get it im sure. i never heard of the AEM gauge drifting off by itself.. usually once its done its done. sounds like your eval was off and you're just getting it inline as you go at this point, unless you have a weak ground or something somewhere.

first post says hks 272.. close enough to stock though.

 

thanks. had those in my car for 4 yrs nice mid range hit with those. good luck with your car

 

i think there used to be an old trick with the RFL's of stacking washers somehow and getting it to hold better. been awhile since ive played with vta stuff, i got over it lol.

depending on how the winter goes, ill be running this turbo on stock cams starting in march, so we should have an interesting comparison. although, im prolly not going to push it as hard as you might.

 

I'm not sure what you guys are talking about in terms of lazy spool. He hits 24psi at 3500rpm and 30psi around 3800. Thats lazy for a stock 2.0?

 

yes it is.. that turbo should have 30psi by 3400-3500 according to my logs of a 71hta on 93. also his car is a evo 9.. mivec.. dont forget.

 

Well, I have 4 washers in there. But the greddy type s has adjusting spring boost reference to bottom of diaphragm and an oring seal. The rfl suffers at subtle lifts of throttle at high boost middle rpm. Rarely but.severe when it happens.


I think it can be made to spool quicker, the fp wga @ should be an interesting comparison.

Ceramic coated exhaust and hotside are in the works, I want to hold my own in street modified and tickle low 11s
