just dyno'ed my FD 30 mins ago
 

297 rwhp, 235 lb/ft-thats quality:D

mods?

Nothing great to talk about without a mod list. :)

nice numbers, but let's see:

-mod list
-boost level (PSI)
-A/F Ratio

also, post a pic of the dyno sheet if possible.

mod list please!!!:)

sanfordman - you are a cracker, those number don't mean anything without your mod list!!!

K

Cool can we get a sheet or something with info. Thanx

I second that motion......WTF post your numbers and then disappear without giving a mods list or answering any questions.

my mods are as follows-
downpipe, midpipe, custom fabricated free flowing catalytic converter, cat back exhaust, hardpipe kit, greddy BOV, power intake and a s-afc. I have to scan the dyno sheet so it will be on later tonite. I was boosting 8.5, 11, 8.5. I would occasionally spike up to 13. If anyone tries to talk you out of an s-afc because they suck dont listen to them. I didnt have the money to spend on an FC commander so I went with the AFC. I bought it and installed it on the dyno-I had close to a 50!!! rear wheel horsepower gain just from the s-afc. My dyno sheet should reflect this becasue I ran a base run before auctaully tuning the afc and out popped 50 RW horses! Funny thing happened on the dyno, we had a peice of 2x4 to hold in the air flow sensor from the dyno in my exhaust and my rex definatly caught in on fire during one of my runs (it was pretty funny but smelled horribly and stung your eyes). Anyways- dyno sheet will be online sometime soon. Sorry about not listing mods-I was to excited and had to run to class because the dyno took to long.

BTW, do you have a street-port or something? That torque figure is low for that much hp. Also, where's the sheet scan and mods!

how would a fuel controller add hp? it only adds fuel so you don't lean out, it won't give you more power.

Was it a mustang dyno or a dynojet?

you said you had both a midpipe and a custom cat. I was just wondering which one you have because a MP takes the place of a catalytic converter.

close to 300rwhp is very impressive on 8.5psi!?!? I figure the spike to 13psi was during transision or what was going on? What was your A/F then?? 300rwhp at 8.5 makes me go WOW as much as rikki's 350rwhp at 11psi

Danny

Good eye :crzyeye:

Uhh. right... you do realize that just slapping on the S-AFC doesn't do a damn thing to your fuel map right?? I am not doubting you picked up 50HP somewhere, but I can tell you right now it was not from that pretty blue screen.

Matt

He probably means he bought a midpipe and had a custom cat welded into place.

WORD......that doesn't make any sense, either I am stupid but I don't see the point in that. Why would you buy a MP and then put in a high flow cat, why not just buy the high flow cat? Unless I am missing something, in which case could you explain what you mean.

Most of the time you can come out cheaper this way, however you might not necessarily get the same quality.

well, in reality if you buy a midpipe and put a highflow cat in from say a muffler shop, it would be cheaper than actually buying an FD specific highflow. And I agree that you can not make 50rwhp from just tuning the SAFC.

Danny

Where in Raleigh did you dyno it?

well i dont think that he made 50 hp from the s-afc itself, but if he was running rich enough before, i think leaning it out a bit could get quite a gain, dont you think? I have the S-AFC, but i avent installed it yet. Im waiting untill i break in the clutch to put it on.

this guy is sayin some weird ass shit, like custom cat w/ a MP. How the hell do u do that??? Oh and the AFC gains 50 HP, just like neon lights do right=-)

how could he be running rich if he's got all those mods and stock ecu. he'd have to be running lean. plus he's using the stock injectors which is pretty damn risky for anything above 280rwhp imho.

Gees let the guy respond, he has only posted 2 post and some of you guys are jumping all over him.

Personnaly I have a Super AFC and I had to lower my injector duty cycle about 10% all the way across the rpm range just to get to about 10.5:1 afr, the lower limits of the afr gauge. Eventually I went as low as -15% to get to about 11:1 afr. I did pick up a bit of hp but not that much.

On another note, I would like to see his afr :)

I'm sorry, but I would have to disagree on this one. Even if you are going by the 85% duty cycle rule, the car can make 305rwhp at 85% duty cycle of the PRIMARY injectors. safe and risky are relative terms, but a car with stock injectors can make well over 300rwhp safely IMHO.

Danny

Nice numbers your car pulled on the dyno.

His torque seems pretty good. I pulled 302 RWHP @ 11.5 psi and my torque was 243 (look at sig).

I was using my stock injectors and I was running @ 12.5 psi, which was still safe for my car. I didn't run more than 13psi, because I didn't want to take the chance with the injectors and I was using the stock ic at the time.

yeah i know, in fact i've seen cars make over 320 to the wheels w/ stock injectors. but tell that to my car sitting at the shop undergoing a $5,000 rebuild due to leaning out. broke an apex seal and scored both rotor housings at both spark plug holes. can never be too safe.

i don't know what your mods are, but i find it nearly impossible that w/ the loss of all the restrictions this guy has, that he would be running rich. then on top of that how can he lean it out even more for an additional 50hp. no fucking way.

Yeah, but he's supposedly only hitting 8.5 psi. I'm not sure how that's possible with those mods but....

Check out Wade Langham's site, he wideband dyno-ed a car with all the bolt-ons and stock ecu at 10 psi, the A/F was still low 11:1. At 8.5 psi, I'd imagine he's not running lean, even with just the stock ecu.

Anyways, many weird things about the whole tale.

Yeah, I posted that before I saw his mods, so I didn't see the midpipe. I would expect a lower torque/hp ratio with a midpipe.

My recent dyno showed 226 ft-lbs with 240 rwhp. Of course, I did have only 7 psi at 6500 rpm, so the hp should have been higher. So...I'll shut up now. :)

I agree that you can run 12 psi on the stock fuel pump and injectors I think that is almost a fact for the fd especially on a port that is very normal.
If you replace the fuel pump then you can run higher boost so the injectors aren't holding anything back.

fdracer: Maybe your injectors were clogged? Fuel filter? maybe you were getting high boost at night in cold temperature or something. There could be tons of reasons why you need a rebuild and were running lean.

Stop blaming the kid, let´s wait for the results, maybe he don{t know too much about mechanics or mods.

BTW who said that more than 238RWHP is very risky? and WHY?

Im sure he means he has a Hi flow cat.If its the same car im thinking of 93 silver on red,Its a custom made cat useing a 3" catco.

I can't believe you guys are jumping all over this guy without letting him respond with a dyno sheet.

Let me go scan my dyno sheet, I have a 255 horsepower run on the sheet where I was not running with the AFC tuned, then you will notice the largfe horsepower gain upon completion of tuning the safc. So in all reality, I guess that pretty little blue screen did give me 50 horses-The sheet will be on the internet soon (freind has scanner and he is not in dorm now). And I used a dynopak dynometer. And about the MP and cat-I took it to a shop which is owned by a guy who has raced rotary for 20 some odd years and he custom welds and fabricates his own exhaust peices, basically I have a 3 inch exhaust all the way up to the turbos.

^yenven knows who I am talking about and my car I think is the silver and red one you are talking about

Cool, geez

here it is fella's

here it is fella's

The 2 runs were I had only about 250 were without the safc, the other runs were with it

looks like you made the runs in 3rd gear

yeah, it was either 3rd or 5th gear, I didnt run it and my eyes were glued to the screen so I wasnt paying attention

what'd you do w/ the safc to do that? did you lean it out?

that is one pretty crazy dip at 5700rpm or so in the w/o afc dyno curve. And is just as crazy how much power dropped off after 6000 w/o the afc as well.

I"m still very curious as to on the 300rwhp run, what PSI was the car at that point?? And are you seq or non seq? looks like a non-seq to me.

Because your original post said something like 8.5psi. And 8.5 psi is still VERY impressive for 300rwhp. Or am the only one impressed?

Danny

oh yeah.....a/f ratios??

I was running around 8 psi, I am still sequential, dont know the A/F ratios, but I do know I was running really rich so we leaned it out a little and got 50 RWHP out of it-go figure (works for me though)

Where was this I ask again?

how is it possible you were rich w/ all your mods. i've never seen this. you should be lean if anything. let alone be rich to the point where you can lean it out for 50 more hp.

yeah, i still don't get it. But he IS only running 8psi, so we can all agree the stock ECU can hold the bolt ons with 10psi, but he's running 8PSI! gosh-darn, he's running 8psi with bolt ons and is getting 300rwhp. I'm jealous.
