Funny you should ask, I have a video of the actual event. Watch at the last slalom and turn the volume up. You can her the pop and chunking that follows. WOT pulls to rev limiter bump out of every turn -- you know, the usual.

The motor was stock on E85 with 123,000 miles. I'm actually surprised it made it that far. I think it broke a rod.



I actually started with a stock 2005 evo in STU back in 2008 I think. But seeing how STU guys buy a set of new tires for each day of the week and have them shaved down to 1/16th the day they come off the rack, I'm not sure sure it's really all that low budget.

 

^^^^ sorry, my CTRL + Sarcastic didn't come through on that statement

 

Every time I watch that video I clinch!!! You do like your rev limiter tho. ;0(

any one else going to the Tour in Cecil??? C

 

What is the average HP/ Torque at the wheels that a STU Evo is making now in 2014 with 93 Octane gas tune?

 

Good luck getting that information out of any of the highly competitive folks... but to give you a taste, probably 250-280hp & 240-270 tq on a mustang dyno, more on differing dynos... much more than that and I bet it won't be shared publicly...

Also it isn't all peak power, but the area under that curve and the shape.

 

Thanks. When it happened I was in shock. I had a mic in the cabin and as you can see, I didn't say a word. Just coming off the end of the run all I could think was - what happened? Did I win? What's that smoke? Did I win? This is going to be expensive. Did I win?

Concerning the rev limiter, I've heard people express concern over this -- but what would be suggested? I don't think there's enough time to shift up then back down before the apex.

 

What is ur limiter set to? Perhaps it's the way your course is designed but I rarely hit mine, then again I may not be driving hard enough. Either your new motor should sustain the abuse you throw at it, I assumed.

 

^It really depends on how fast the course is. My limiter is at 8000 and I hit about 67-68 according to my datalogger. We have courses quite regularly where I'm either on the limiter, or I have to shift to 3rd. Last season we even had a ~85-90sec course where I was in 3rd gear 3-4 times (including once in a slalom).

 

WOW, thats a pretty fast course and Im assuming with decent amount of straight???
The courses in our region RARELY has a straight line long enough to top 2nd. for example. C

 

This was my 05 Evo in STU trim, 91 octane vs 100 octane tunes. Draw a line between them and there's your 93. Same tuner, same Dynapack dyno, though the 100 tune was a bit more conservative and done in hot weather. Stock intake, stock O2 housing, ported stock exhaust manifold, 3" turbo-back. I would expect the 06 cars to do better. The car placed well at national events (not with me driving!) so it was certainly competitive.

 

Brain –Thanks; I was actually expecting to be completely ignored

I don’t want to open a can of worms, but I guess I have to:

I searched everywhere and I can’t find any baseline/ idea. I understand that there are many ways to measure and deliver the power, and people will never give you the real numbers, but I can’t find anything…

How do you know if your tune is making competitive STU power? Tuners are not used to tune without touching the boost tables so this is not really the norm.

From Vorshlag Motorsports Evo X MR Build:
“Special thanks to Cobb Tuning Plano for all the last minute help prepping the car. Cobb aligned it and flushed the brakes the day before. The car never overheated, never detonated, and provided nothing but 320 whp all day long!”

(I am also running an Evo X but a GSR)__So Cobb was able to get about 320whp
with a STU tune back then, and since tuners are more knowledgeable with the Evo X now, maybe a bit more power is possible?

Can we have a STU horsepower gentleman’s agreement?

 

I seriously doubt thats gonna happen. 320 AWHP on STU tune is a bit high IMO. maybe possible with a IX or X with their Mivec, But most Ive seen are right under 300, tough to get more with so much restrictions. C

 

On a dynapack sounds about right, subtract 20-25hp for a mustang and you are competitive anyway...

evoX likely needs to have 320+, and still the weight will kill it when limited to 245s, this has been discussed many times in many other threads, lets not clutter 2014 STU thread with rehashing all that.

~says the guy in the mid 2900lbs STU car

 

Butt Dyno shared his latest STU dyno in this post: https://www.evolutionm.net/forums/9895368-post144.html

290whp for him on a IX. Not sure where an X would fall though.

 

Wait…what? The Evo X is not competitive in STU?.... no need to clutter the thread. I know.

I was genuinely trying to gather information about approx WHP because the lack of data regarding the X.
The only STU Evo X figures I have seen is the 320WHP from the Vorshlag quote above, and they were tuned with 93???

I figured that the IX should make similar or more power, also all the power figures a see are from years ago…but I understand it is a delicate topic, so let’s just leave it at that…

Hopefully I can compare some meaningful data this year with (Butt Dyno) since we both run in the DC area.

I am praying that my car is at least 3,400lbs, I should know soon.
