no fuel calculator will tell u that 4 550cc at 38psi and with 11:1 afr will give u 280 hp...and if it does its not accurate at all

 

when it says the stock ecu runs at 56-63% that means that...

the 86-88 turbo II making 183 hp. the 550cc's open to 56% duty

and the 89-91 making 200 hp. opens to 63%...

make more power with either. and both ecus will go alot over 63%....


and for the main post on this. there is no way you should be going lean at 10psi at 5000rpm... something else is wrong with your car. my S-afc at 10psi with stock injectors and FD pump is in the negitive %. as in I leaned it out!...

 

at 38 psi in the rail with the 13.2 AFR with 550 cc injectors and 220whp or about 275 flywheel hp they should be either maxxed or running close to it...u cant calculate this percicely since there is not enouf data...so on the car it should be diffrent.

like i said before, his fuel pump is either not working right, is wired wrong, or his injectors are clogged, getting a fuel pressure gauge will help diagnose the problem further...

 

Scott 89t2- you realize the 88 T2 was under rated in the US right? I dynoed 178rwhp STOCK, 5.5 psi, and so have many other people, so that comes out to around 215 flywheel hp, which was the hp in japan's infini...

 

That's what I'm thinking... from what people have said with their Warlboro/Safc results on dynos, no one has seemed to lean out at 10 psi besides him. That's why I asked when he last had his injectors cleaned and flowed. Thats how I blew my engine.

 

i got my car dynoed and i thought that was low for my mods (below) found out later on that my car is running really rich 10:1 a/f ive had it tuned a bit but nothing major and it goes heaps better. i also just bought a FMIC and its going on soon and with a dyno im hoping to get aleast 250rwhp

 

I've never heard such things!!

 

You're right.&nbsp In absolute value terms, it's a "small" number.&nbsp In reality, it kills gas mileage - if not retuned, it'll cause a 15 city/25 hwy FC to produce 12 city / 18 hwy mileage, which is horrendous for most people...

holy tripple post batman.

 

Yeah, I've noticed a big decrease in gas mileage.

Gsracer: maybe you should keep your post counting to yourself, or find a new hobby... we don't need people stating the obvious.

 

ted sucks

 

I'm a bit curious now... because your sig says 210rwhp @ 14psi. How much torque did you get, and do you have dyno's? I'd love to see what your torque/hp/afr curves looked like. BTW... I should also state the obvious, but if your turbo is just blowing hot air @ 14psi (which seems like it if you're making less power than T210thAnniv @10psi), then maybe that is why you don't need the bigger injectors. Also, is the 210rwhp corrected or uncorrected?

Thanks,

Boris

EDIT: oops, I just noticed that you were running rich, so partly-ignore the "hot air" comment )

 

Which calculator did you use, and what did you use for values? I actually just used a calculator as well, and my calculator supports my theory....

LMK...

Boris

 

Damnit that sucked...or am I trying to pad my post count?&nbsp Post *****? *grin*


-Ted

 

So which is the "*right*" to do do it?

A pump and a aftermarket FPR to regulate pressure back to normal?

 

Yes, but it takes time to do that.&nbsp Most people just buy an A'PEXi S-AFC (or equivalent) and jack the pulsewidths down.

if your car is tuned properly and u keep the same driving habbit your gas milages SHOULD NOT decreese

 

Kahren, I think he means untuned with just a fuel pump (increased fuel pressure).

 

I'm getting 12mpg on highway estimate... I have the #'s but have not done the calculations.

I think I have the bad gas mileage record for non-ported cars

I got about 180 miles on my last tank.

and the wierd thing is... there are no funky smells coming from exhaust except for normal, no bleeding sore eyes, no smell from the engine compartment, etc etc... though it does backfire a good bit and it bumps coming off the idle.

 

i just had one more question, i am getting the fmic soon and i was wondering if i should expect to gian boost or would it drop from the piping beening bigger? i heard both and i am kinda scared that it might boost alot from it...

 

a front mount is not going to increase your boost. However with the front mount it will be safer to run more boost as the chance for overheating the air and in return causing detonation is much lower. The stock top mount is in a pretty crappy location to begin with and over 11-12 pounds of boost it becomes really ineffective. If you have really hot air being thrown into the engine this makes detonation that much easier. You might notice a little more lag, but then some people say that a front mount had little effect on lag at all.

 

3 months later I was searching and I found this old post. Couldn't help but pass it up.

I'm in the mid 11's for a/f ratio at 10-11 pounds.

232 rwhp.

Still just the walbro.

 

Those are the same numbers my car got with RB Turbo back and AFC. I was only getting 8psi though.

220whp/215tq
