Stock ports. Stock turbo. No boost controller or S-AFC .

How's my A/F ratio? Not sure what it should be at. Decent power for mods in sig? What should i run the 1/4 in? What should i do next?

so you have intake, exhaust and injectors. if i were you i'd get a fuel pump (walbros are only 100 bucks) and an safc. you're running a little too lean between 5000-6000 rpms. get an safc and richen up that whole range between 4500 and 6500. with 201whp/201tq i'd guess you'd run between a 14.0-14.4 in the 1/4 mile @ 92-95 mph

EDIT: i find it odd that you have 720cc secondaries, a spearco FMIC, and no fuel controller and you're running *lean* at ~10 lbs.
buy a fuel pump. your stock one probably isnt keeping up with those big secondary injectors.

Wow, I would not floor your car above 4500 rpm until you find out why it is so lean. You are running damn near 14:1 above 4700 rpm. Did you put the 720cc injectors in the primary or something?

Like said before you need a fuel pump, fuel pump rewire to make sure the power is getting to the pump and a safc if you can get one. But never the less go back to the dyno.

And lay off the gas or you will be replacing a motor soon if you continue to run that AFR above 4500 rpm.

O.k. I wasn't sure if it had already had an aftermarket one from the previous owner. What should my ratio be at?

Are those numbers decent?

Wankel7

You should try to have at least an AFR of 12:1 - 12.5:1 under wot with full boost. Yeah, those numbers are good. However, consider the fact you got those running VERY lean. If you keep running like that consider your dyno run a nice momento from your toasted engine.

Check the voltage at the pump, change your fuel filter, and go with a walbro or fd pump

pretty cool

where is everyone gettin he is running very lean...? perfect a/f ratio is 14.1/1 a safe ideal a/f ratio is like 13.9/1

drago86

13.9/1 + turbo rotary = BOOM,.. do some research before you post.

I found my new walbro 255 on ebay for $75/shipped. Well worth it and a like 10 minute install.

please do not post **** like this or more people will be blowing their engines.

if you had cared to read, you would have noticed that he has a TURBO rx7m not an NA.

for tuning turbo cars you dont want an AFR anywhere near 13.0:1 AFR's or you will be buying a new engine. ideal afr's for stock turbo'd turboII's is high 11's low 12's.

i didnt see anyone respond to if those numbers are good. I think something is off. I put down 188 hp 194 lbs with my ae when it was stock except for the main cat was removed(precat still on) stock exhaust exept for mufflers and a cone filter. my best time was 14.4 with alot of wheel hop. Just something for you to compare to.

To be honest, I think the power numbers are lacking for your mods. Without a ported wastegate you should be seeing more boost and thus higher numbers. Of course it IS good you aren't boost creeping, but I'm wondering why.
