numbers aren't bad, I might expect a little more out of a dynojet though. let's not turn this into another ka vs. sr debate guys

 

Let me guess you dyno'd on 91 pump gas...
That seems about right.
Sr's are constantly fighting ignition on boost, if you raise the fuel (AKI) requirement to at least 98octane you will see higher numbers.
Street fuel sucks these days and sr's don't show the high HP numbers they did 10years ago. Most street fuel has 10% ethanol which will be a huge drawback on power.
Thats about a 7% loss in BTU output rather than using 100% petro base.
Your dyno is relatively correct.

No SR-KA debates, each engine show there own high and low points and sometimes can't be relevant to cost build. Everyone is different.
I'll close this thread if I start to see this conversation sway in the wrong direction.

Meeh, my friend Anthony has HKS stage 2 cams and a T28, with the enthalapy tune. He's barely braking 200WHP @7PSI with 91 pump gas with his red top SR. The tunes are over rated... I'll actually be fine tuning with an SAFC to get the pig richness out of it..

 

dude that dyno was wack.

some dude got 151hp 212tq out a KA.

if anybody is gonna get 150+ whp out of a NA KA its you dude.

not some random dude.

the only reading that made sense was Ant's.

 

There was an RB20det on that dyno that only made 150WHP...MU HAHAHAHA LOL.
A fully bolt on VG30de that only made 163WHP...LOL That dyno super sucked...
Anthony only measured 183WHP on that dyno, but he's really making more into the 200WHP range.
we were originally going to put enthalapy on blast until we realized how inaccurate the dyno was.
Bayarea240sx is having a dyno day with BRG racing in June because we were super disappointed with those results at freakmont.

 

Yeah big vinnie, it was on 91 octane. so you think if i was on 93 it would be any different.

i have no idea what your talking about Ayuadddict

I really dont want to go standalone. i know its superior in just about ever way than a ecu flash and a piggy back. but i dont think my setup is worth spending $1000+ on engine management. And i know a safc isnt going to cut it.

I have a buddy here that keeps preaching to me about efi specialists. they tuned his ecu for his ka-t. and hes been running 330whp on his dd for about 8 months now.

so im not totally decided about enthalpy

 

safc will cut it if you keep it below 550cc injectors lol... its nothing wrong with it. its a basic fuel controller thats all.. the issue is.. guys just feel that if they spend 1000 Plus on some EMS that they will have no issues lol.... hahahah is all i have to say to that and nothing more.

 

Yeah dude if your using a T25 at 11PSI your air is mildly warm. T25's are worthless at about 15PSI because they get too dang hot.
This means your cylinder temperature gets up there in heat range. A higher Octane will definitely mellow out the heat factor a bit and show better HP numbers, may not be huge numbers but better than what you had before..

I would use about 4 gallons of 91pump gas, and a gallon of either xylene , or Toulene.
Either that or order some TORCO or VP racing gas.. Those are all high potency octanes.

 

Biggahitme: so are you saying safc is fine UP TO 550's? because thats was im going to run here in the next 2 weeks.

BigVinnie: we actually have 93 octane here in sc, but i was forced to get 91. due to not having any fuel at all and that was the only thing available. with my t28 i will only run 93 in there. not every gas station here has it. some gas stations here even carry 95 octane, but those are very rare.

Has anyone here ran a n60 mafs rather than the z32 one? if so, how should i setup my safc to work with the mafs. thanks

 

awsome numbers.

Now its time for a T28 and bigger injectors

 

s13nismo

Yes the safc is fine and can control up to 550cc injectors.. when using the device in conjunction with wideband its an awesome tool.

i am running a N60 maf (wire up the same as z32 maf) which you can have from the older maxima's 89-94, they are also the same maf's that come with RB20's etc. I am not sure where they max out at in HP personally.. ill be able to tell you in a few weeks... from what i have gathered they are good for mid 300ish numbers

 

the gas station next to my house carries 100 octane and 116 octain but that ish is expensive

 

oh ok. ive read that the n60 is good to about 350ish. but im hoping for 280+ so that should be fine.

Anyone here knowledgable about the GTiR T28?

We have stations around here that carry race fuel too.

 

GT 28 usually comes with a good A/R. Allows you to boost just a tad higher than a T25. I'm pretty sure that T28's come in the same housings as T25's. N60 MAF is fine I use it for natural aspiration. Using the N60 will help your low end torque band....

 

i want my sr bigga saved me from wasting money lol but sounds nice man around here the highest octane we got at the pumo is like 93 but about 20 miles from me they sell jet fuel lol (to jets) but i get all the race gas i need my town is a racing town (imca)

 

huh, wasting money?

what do you expect from a 2.0 4cyl with a small turbo ?
