Well, As I said long ago I would be the first to correct any error in claims. I hit 163.2hp with 155.9lb/ft @ around 7500. The hp and torque curves are nearly identical. This is with wired 6 ports (I absolutely hate how the car runs like this) but, my new air over mechanical actuation system is still in conception so I ran it as-is.

The scanner here is on my dads comp and I don't know his password so I'll post the graphs from school tomorrow.

I have a nasty lean spike at 4500rpm and the top end was near 12:1 so I have a lot of leaning out to go. (the dyno wideband kept reading lean so the tuner kept fattening it up) We also thought that lean spike could've been ignition related so we backed the timing back down to just ATDC. So these #'s are with a retarded ignition.

Feel free to post whatever you want in the meantime.

Some other rotary knowledgeable guys were there and seem to think the S4 ecu is the problem. I personally will be getting my aux ports functional again and will take it back to see how it does when its running better.

 

Yo,


Yep, the Dyno is evil. I thought I was gonna dyno 160ish...I did 140.

Good to finally see some numbers on the Supah NA Motah.

What do you run quarters in with that thing?

 

all the work you have and you're using the stock ecu? i'm curious about the 1/4 times as well.

 

I don't think the dyno is evil at all. I have 30 more lb/ft of torque than any other n/a graph I have seen and it's a straight line from 4 to 7K. My fuel issues and retarded timing account for the crappy top end, but pp13bnos' 167 is only 4hp higher than me running in horseshit tune... I know if we had done another pull with the timing at 10 degrees BTDC I would have eclipsed him with all else remaining the same. (and I still kicked his *** in the grunt department)

I was pretty tired when I posted the original post last night. The timing for these runs was set to 7 degrees ATDC. I had meant to say "retarded from stock timing."

The dyno graphs will surprize a good number of you. I'll be posting them after my final tonight.

I am dead broke... Doing this dyno run was a present to myself (with borrowed money) for getting the highest gpa in school I have ever attained this term. I can't afford a ******* stand alone so that is why I have what I do. Anyone wanting me to get a haltech feel free to send me one. I'll give you my address in a PM. My rent is going to double next month and my income is not. The car is not going to get anything special untill my finacial situation changes in a big way. So do me a big favor and just don't say "oh you need a different ecu," because I've known that for the last 7 months.

 

dude those are really good numbers if you are n/a and it looks like you are. I am yet to get my n/a on the dyno but would thrilled with #s like that.
but def try to get your car running the way you like it too. that is what is important. what is important is ae you having fun when behind the wheel, not #s.

 

I dont care what anyone says, those are some killer numbers for a NA.

 

I'm only pissed because I know it can and has done much better. Issac is a very knowledgeble tuner, but he fucked up my a/f maps before even doing a full pull. I had it pretty close to where I thought it should be and he hosed that before we even got a base reading.

You guys need to see the graphs... I'm betting I could've seen the high side of 180hp yesturday had the maps been left alone. I'm 1.5 points rich at my max power.

 

165 lb ft out of an NA oooooooooooooh it's not a 6 port motor haha nice job!!! sweet #'s truly an NA to ENVY

 

Jimmy, what are targeting for A/F Ratio? 12:1?

 

It dipped down into 11:1 territory around 5500 (after the lean spike of 18:1 and my torque peak of 155lb/ft) and then went back up into the fat 12/13's

I was looking for 14.2:1.

This IS a 6 port motor people.... Maybe only acting like a 4 but it is a 6 port.

I also have a confession to make about my torque curve. I was looking at the wrong printout. My torque curve is super flat and doesn't follow the hp curve. Its so close to my a/f readings I screwed up what I was looking at last night. When the a/f goes lean, my torque skyrocketed. (which also leads me to believe this was a bad dyno session)

Time for the final. I'll be back with pics in a few hours.

 

those #s are great but I am gonna have 2c 2 believe those tq #s. but nice pull, and be sure to post the #s next time after you get that thing leaned out on the top end.

 

Hey jimmy, one very important question to ask you...what mods do you have?!? I don't remember ever seeing what you have (what year is the car etc...more like what manifolds and block are you using). Those are some GREAT numbers, but I can understand why you are unhappy with them, that'd **** me off too. But think of what you do have and be happy til you can fix it .

 

screw the dyno. Run the 1/4!

 

Couple questions. First, what did you mean by more low end grunt than me? You just making more power down low than me? Also, what kinda dyno did you get it tuned on? Unless you had it on a Mustang, you ain't go nothin on me. If its a dynojet, add about 10% to my dyno, to compare to yours.

For your guys info, the GTU will be going back on the dyno very soon. Last time I had a working 6 port system, and the stock flywheel. As most of you know, I've gutted the 6 port system, and put a 17lb RB flywheel. If nothing else, it'll be interesting to see the difference a working 6 port system, vs a gutted system. Still running the Pineapple Sleeves though.

Its kinda a honor to be the bench mark of n/a 6 port horse power levels.

Also, are'nt you running a monstor street port?

Please post it soon Jimmy! And nice numbers. CJ

 

Ill beat you both sometime. Hell I might be close to both of you right now, cant wait for engine management...

 

Also, that thing makes some awesome torque! My car made a peak of 125.7, and my old efi peripheral engine only did 176. Now you're making some realy nice torque numbers. CJ

Also, If I get desperate, I allways got the blue bottle for backup. Then you can add anouther 150hp to my numbers easy.

 

Can you post a complete mod list for me. Id like to see what kinda of mods you have. Thanks.

 

Dual 2" manderl bent exuast (True duel), cone filter. Removed double throttle, and coolant flow to TB. Ported black elbo before TB. Ported upper, middle, and lower intake manifold. Pineapple Racing 6 port sleeves with removed 6 port actuating rods and rods through the sleeves. An extremely mildly ported 13B built by Pineapple Racing. Jacobs ignition wires, Short shift kit, with FD shift ****, T2 fuel pump (stock one broke), Hi-6. and a Apex S-AFC. 50-150 shot of nitrous. Sqeaky front left brake.

Last dyno 167rwhp@7500rpms, with working 6 port system, stock flywheel, no nitrous.

Thats a complete list, and hope it helps. CJ

I have a dyno sheet of a 166.4rwhp run, but never got the 167.1 one. The car also put down 170rwhp once, but we had the input weight on the dyno set at 3,000lbs, instead of 2780lbs. I'll post it.

 

Thanks man.

 

Maybe that thing would put down 180 with a larger street port.

 

when you see my dyno you'll understand where my 180hp comes from. the lean spike actually opened my eyes to how badly the fat condition was killing power. both the hp and torque numbers go through the roof when the fuel cut out.

I have to do some image tweaking (rotating and resizing the scans) and then the true analysis can commence. Should have stuff posted within the hour.

 

Come on, come on, let's see it

Looks pretty good! I'm surprised it's as smooth as it is at 6750rpm -- My car just barely fires correctly at 11:1 (anything richer leads to lots of misfiring). That's at 16psi of boost too, so I would think that it'd be even worse on an NA engine!

Wicked torque curve
