Im running the drop in Works filter, Works 76mm ceramic dp, Works HFC, Works intermediate pipe and muffler. Also have p2r flash with boost set at 20psi and tuned for 91 octane. From bottom to top, the lines are as follows: AFR, boost, torque, horsepower.

As you can see, the AFR's are REALLY nice. I think he gave me the wrong graph for my 300hp run, this was the run with stock filter hence the dip at the top and 5hp difference. We tested the works filter on 2 different cars, made 5-6 horsepower on multiple runs. The graph for the 300.3hp run was SMOOTH. I was very very impressed with the mail in tune. No dips, and torque is flat as a table.

Highly recommended! Specially since this mustang reads notoriously LOW

 

so are you saying that the car made 300 whp and 269wtq? or is it the numbers above, 269/241?? - also did you dyno the car stock and what did it make?? and what size intermediate pipe are using/ and which muffler?? thanks - steve

 

The 300/269 is corrected numbers on a low reading mustang. On a dynojet the numbers would be well over 300. Car wasnt dyno'd stock. On the same dyno on the same night, another friend put down 284 corrected. He has 3 inch works dp, works HFC, works drop in, and greddy titanium catback. He has no flash at all, and no boost controller, but he does have the works 3inch o2 houseing.

 

300 and 269 at the wheels correct?

 

Do you have a graph of what you made before the modifications?

 

That torque curve is impressive, i'm not sure if i have seen that on a stock turbo'd Evo yet...

 

I'm used to seeing the peak torque and peak horsepower numbers being more equal. But the torque curve does look very smooth.

 

Just thought about this one.. they tune for 20psi peak, so the torque spike won't be as high, but it looks more sane than ones I've seen. (usually see a big dip in the curve after peak boost) This torque curve is "as flat as Montana"

Does Works not recommend tuning above 20psi for safety reasons?

 

I have an VIII and I was thinking about getting the WORKS filter and 10.5 hotside. All I have is TBE w/ test pipe. I'm hoping to put up similar numbers. Although I don't have the MR DV tp hold as much boost.

 

Works does not recommend tunning above 20psi i spoke to oliver he said that if you have 4 people inside the car and ur going uphill u might pull a timing. I was talking to some guy he had vishnu tuned he's doing about 24 psi on 91

 

damn might even get some detonation when I'm hauling some cement for my deck I wouldn't get on the car with a heavy load uphill anyway

 

That trq curve is normal like most evo 9's. It doesn't seem to dip because the scaling on the sheet. If you look at the actual numbers you will notice it drops like other evo 9's do. from 269 at peak to about 200 ish past 7000.

Also, if these are corrected numbers, and it's Vegas in sept, well......

269.8whp@6468rpm and 241.8wtq@3558rpm look to be the uncorrected numbers. So that is what you where really making. Corrected numbers only work for bragging. Either way those are peak numbers anyway and its the actual curves that matter.

WCF = Weather Correction Factor.

 

ur 109 trap is about 325 whp on DJ.

 

What I meant by dip is that I have seen a lot of evo 9 tunes where there's a valley in the torque curve immediately after peak torque. It then picks back up after a few hundred rpm, but it doesnt looks as consistant as the graph in the OP. So I didn't mean that the torque curve eventually declines. That's always a given.. unless you drive an s2k.

However this dyno reads, his trap speed is not bad at all for a 20psi tune.

 

Trap speed of 109(them there braggin rites) that he is sporting makes me believe even "corrected" is conservative. WORKS tunes do dyno with a nice flat torque curve. I own one too..
