Ok, the results are in. Ive had the M7 DFIC and exhaust on my car for about a month now. last tues. I went back to NGP to see what gains I've made after the ecu adjusted to the new mods. I must say that I was a bit disapointed with the gains. Ripper put down 186.6 and 166tq. That's up from 180.1 hp and 162tq. Thats a gain of 6.5 hp & 4ft.tq. I expected that much from just the exhaust and 4 or 5hp from the DFIC. Maybe if I get a tune from Lucky Dog or Helix I would pick up a few more. I spent 1624.00 before shipping for 6.5 hp & 4ft.tq., what a bummer!!!!!!!!! Where that effing m62

 

Ok now the info is there. First off, you will not see any HP gains at all from an intercooler on a dyno. You cannot push enough air through it to have the effect that it has when you are going 80+ mph on the road. Throw the dyno in a wind tunnel and thats the only way you will see what it does for your car. You have to understand the only time the intercooler is doing its job is when it has a lot of air moving through it, it cannot be measured while the car is standing still. Especially when you haev done a few dyno runs the engine is getting hot and running hotter and the power suffers since it is not being propperly cooled.

Also, ask Peter at M7 himself, no matter what exhaust you go with you are only going to see 4-5hp gain on any cat-back system, including his. Thats just the nature of the beast.

sorry for the long wait. Imust have hit the enter key and kept typing. I type real slow

 

time to drop the sc m45 or 62...
straight to turbo is the key to success.

 

You took the words out of my mouth .Exhaust systems will at best give you 4 or 5 hp no matter what the adds say. As for the intercooler they all will have a hard time showing gains on a dyno especially one that has the benefit of better flow such as your new DFIC. From what I can tell everything about that system was designed to capture flow to offer better performance. With out that air flow you are taking away the very thing that it relies on to perform. A fan will not cut it either . The real differance will only be felt by the improved driving experience which according to many is very noticable.

 

Which exhaust did you put on?

You might want to get ready for the onslaught that is about to hit.

Looking at his post it looks like he put on the "M7 DFIC and exhaust" so I am assuming it is the M7 exhaust.

Thanks!

 

RIPPER, what other mods do have?

 

This man speaks with wisdom

The DFIC will preserve hp rather than create it..... I have been monitoring my IAT for a couple of weeks and I can tell you that there is a difference when the air is cold...... I like the DFIC.

As far as a cat-back.... dyno it again in a week and see if the numbers are the same..... the Mini heatsoaks like crazy on the dyno


as far as the turbo goes.... I very much like the turbo only concept...... to make BIG numbers it is the way to go...... the 62 and the turbo are not in the same category..... I was just not comfortable with the turbo even though it is the fastest way (maybe the only way) to really big numbers. that being said I really like my car with the 62 on it.....

 

Same Dyno?
Same Temperature?
Same Humidity?

You may be experiencing the dreaded dyno inconsistency that drives many tuners crazy. Many conditions can skew the results.

Enjoy your car!

 

Exactly - which means that a car with ONLY a DFIC should not show HP/TQ gains over stock numbers but at best hit the stock numbers the engine should be producing.

 

correct me if im wrong... I've been thinking this in the back of my head for some reason and haven't ever posted on it.

Isn't even possible that the DFIC would actually slump your hp/tq numbers a bit on the dyno over the stock IC. My thought is, heatsoak asside, that the dfic being a bit bigger will provide a pressure drop over say the stock IC. Couple this with the fact that the dfic isn't made to use at a standstill and in my mind you actually have the chance to see smaller numbers since you aren't taking advantage of any of the positives of the DFIC.

of course... in application... the opposite is true.

either way. you may have spent some cash but your car is at least where it should be for a moderate amount of modding... and you aren't all that far off the magic 200 number.

 

did they strap a fan to your i/c ? they strapped this vacuum cleaner looking attachment to mine to force air thru it . they also ran the big!!!! fans too .

 

... there is a small pressure drop with the DFIC ... MSFITOY reports fractions of a lb and this jives with M7.... the cooling is very, very good.... I have been interested in this in maxing out the 62...... on the street the DFIC really performs nicely...... the stock piece will probably dyno the same if not better.... in fact there is a known comparison where on the dyno there was no difference (now that I think of it) when the car gets moving the DFIC works very well.... if it didn't why would two other companies copy it.....
