the red lines are what i came to the dyno with , and the blue lines are what i had after i tuned the S-AFC. the car has racing beat header, presilencer and catback. also has an intake , pineapple 6 port sleeves and the engines is mildly street ported(mostly the aux ports).

 

Looks like you have a slight 3800rpm bump. The SAFC really gave you about 10-15hp up top

 

no to bad for an n/a... it should rip pretty good

 

good numbers man! Nice to see some ppl actually goto the dyno

 

Kahren


Did you use a wide band and which one?
How hard was it to tune your S-AFC?

 

nice you revved the sucker to 8500rpm eh

 

wow, that pretty good!

mike

 

they used a "sniffer in the tailpipe" o2 sensor, not sure what wideband but teh box that it was connected to said dynojet on it.

it wasnt hard at all to tune the afc, u do a base run, look at teh fuel and go from there, dont lean out too much at a time since u can go too low and blow it if u a re not carefull. i tuned to those afr's from the research i have done. so its up to u what u tune to.

 

That's a pretty good advertisement for the SAFC!

 

WOW!! ...How much HP do you guys think I'd put down without the streetport, because that's pretty much all I'm missing.

Great numbers btw

 

Nice!

 

is that blip when the 5th and 6th ports open?

 

the blip at around 5k is the VDI (variable dynamic intake)

and the little dip at 3800 is the secondary injectors and aux ports start to open

 

Hopefully this has convinced you that removing the rev limiter is a waste of time.

 

What AFR numbers did you used as target?

BTW - Congrat on those numbers!!

 

How much did it cost to dyno that? How long did you tune it? S-AFC is like $400 right?

 

YOu can find an S-AFC on ebay for like 300 shipped. Mine was less but defective.
Check out the store they have it for like 350 plus shipping.

 

Nice numbers my man. Is that on stock ports? I cant wait to get another S-AFC, my other one got stolen from my room. I didnt even get to put it in, haha, anyways, how much did that dyno cost you? if its worth it ill do that or get that DIY Wideband and try from there. Hell, i dunno.

 

yep this has convinced me to stay under 8500
seems like shifting around 8200 would be best

i targergeted 12.8 from 6k and up
13.2 from 4k to 6k
and mid to low 13s 4k under

i bought the safc used for 200
i sat on teh dyno for about 30 mins and made 5 runs
this was 50 an hour for tunnig for this dyno day i helped organize i didnt even take the whole hour cause i felt that i didnt need to tune any more

 

What mods do you have done?

 

btw this is a stock FC dyno witha HEALTHY FC putting out 128 at the wheels







this is the diffrence btw from before and after the port PLUS teh addition of a header and pineappple 6 port valve sleeves(also as u can see my 6 ports werent realyl working right and had so much carbon that they werent really movign properly)

 

this is another comparasent with my car now and a another S5 NA with RB catback, highflow cat, downpipe and intake.

as u can see my car now makes more power EVERY rpm

 

please read teh first post again

 

Nice job Kahren. That's about what we put down in one of our street ports. Wanted to find out how your idle is with the street port and who did the porting. Much appreciated. I'm gonna use you as a goal for my GTUs.

Thanks, Rishie

 

nice numbers. Maybe I will get an S AFC. I need to figure out when I should hit the dyno. Thanks.
