I'm not sure if you took the time to read the entire thread, so I'll repeat myself. DIFFERENT EVO'S PUT DOWN DIFFERENT NUMBERS!

My car put down approximately 220 HP bone stock on one Mustang dyno. I was in Dallas at Wasabi and saw a bone stock Evo put down 250+ HP. Should you check all the possible sources of leaks? Absolutely! Should you try to eliminate all the variables? Of course! Will all Evo's put down the same numbers? HELL NO! There are "freaks" out there that, from the factory, put down great numbers. The point I'm trying to make is that they are all different. That's why I suggested that he be concerned with only his car. Unless, of course, he wants to trade his in and try his luck with a different car.

 

Wait, say it again louder and let me put in my hearing aid But seriously, you're absolutely right in principle. But you gotta admit, a 30whp difference between his #s and everyone else on the same day, same dyno with the same mods/tuning is pretty extreme...

 

this is what I'm talking about ^^

 

Again, on the same day, same dyno, bone stock Evo's can be 25 to 30 HP different.

Go back and look at his numbers. After BASIC mods he put down 234 before tuning. What do you think he was making before the mods? Maybe 220? After tuning he was at 262. Sure there were guys making more. But what does that have to do with his car? He's got two boost gauges and he said he was running, I can't remember, like 20 psi. You don't have a leak if you can hold 20 psi. I had a leak and put down all of 168 HP (very humiliating). I couldn't even hit 1.0 bar. He's offered no info on mileage or number of launchs he done, so it's pretty hard to even suggest that he's got a slipping clutch. I'm sure Mark would have detected that when it was on the dyno.

Some guys cars just don't make big numbers, some do! Eliminate all the variables and worry about your car only.

Peace

 

maybe your baseline was low because you upgraded your fuel pump before you were tuned and were therefore running insanely rich. you have any air/fuel charts from the tuning?

 

Hey bro I went from 259 to 289whp with cams today. I was figuring more WHP but that dyno we were on reads very low. Look at the kid that put 550whp down in Tampa and then came to this dyno and only maxed out at 466whp. I am very happy with my tune and I think you should be as well. You are probally a bit over 300whp on a real dyno.

 

you dyno'd on a mustang dyno. they under-rate horrendously as the dyno actually applies a 'real life' type load to the car over typical dynos like dynojets. on a dynojet you'd make a crapload more whp. who cares, its all about seeing your gains and how much 'area' you've gained.

 

17K Miles, no launchs, never been to the track. This is a daily driven car. I understand different cars put down different numbers, but not to this extreme..even according to Mark. Mark gave me no explainatins other than maybe a boost leak, but to loose that much HP, and to have 2 gauges showing no problems it kinda wierd. The clucth could be slipping, but Mark mentioned nothing of it..and like I said this it a daily driven car.. no races.. no problems ever noticed with the clutch....

 

Hi,

Another thing to do is go back to the basics- check your compression, maybe change your plugs, etc. If everything checks out, you may just have one of the lower horsepower cars produced. As others are suggesting, the stock outputs cover a range, not everyone makes 271/276 stock at the crank. Don't get discouraged, though, just think of it as more of a challenge to get to your power goal. Even if you need a larger turbo or something along those lines, I am sure that your car is capable of 300 at the wheels, and I'm sure even more.

Good luck,

Never dyno'd!

 

Your dyno #'s are looks really good. With the addition of 272/272 cams one may expect to see ~30 hp and ~20-25 lb/ft of torque.

 

You keep saying I have two gauges and they indicate that you have no leaks. You will not notice a boost leak under full boost. You have to pressure test your car to see if you have a boost leak you can't go by the gauge. You could see a vacume leak at idle but a boost leak at wot is much harder to find. I live in sanford and can do a pressure test on your car if you want. I was at aerocomp today als, but did not run. I had the blue evo with the fmic and cams. If you want to pressure test your system I have a compressor and fittings to do it and we can look for leaks. If you want to do it pm me and I will give you my phone #.

 

Not exactly, Mark tuned mine on a Mustang dyno. You're right about the stock dyno, I pulled a 219.6. After my mods, which are almost the same as his, I ended up with 295.9. But like everybody says, ALL Evos come with different WHP...it's just the luck of the draw I guess.

 

This dyno read extremely low in every case dont worry about it. Mark was saying it was reading low. If you go somewhere else to dyno I am sure you will see a improvement. Honestly go to Tampa wherever the last meet was and dyno there i bet you are at 300whp.

 

Hey man nice to here from you.. after you left a evo with no cams and less mods pulled the same whp as you.. and he had a higher tq #....and he was b|tching...

 

Thanks, sounds like a good idea..can never hurt with a new set of plugs and I'll have to find a place to check the compression...
