read in mc2 today that the gp puts out 218 compared to reg. works' 210 because of the redesigned intercooler. so are they saying the two cars are equal on the first pull then the gp has less loss on subsequent pulls? or are they saying that right from pull one the intercooler is better . if so then i'm getting a dfic asap!!! i mean are we talking about the tree no one heard falling in the woods or did it just fall on my head? (passes blunt to left).

 

The GP intercooler is bigger, so I'd say that the it's better from the start. The additional cooling outweighs the additional pressure drop across the IC. It's been suggested, though, that only half of the extra 8hp is from the IC. If I recall correctly, the GP also has a higher redline so it gets a couple extra peak hp at the top of the range.

 

so if i go get a dfic i'm gonna pull better than now ?

 

I don't know what you have now and I don't have first hand experience with the DFIC, but every review I've read raves about the improved power.

 

i'm doing 212 at the flywheel at 6000 .yeeeeees

 

How are you measuring the flywheel horsepower? Did you have your engine out of the car on an engine dyno, or is that an estimate based on a WHP measurement?

Does anyone know what kind of presure drop there is? I heard it was minimal & far less than stock. The IC looks to be about 1/3 larger, bigger is better....

 

yeah whp was 177 at 6000

 

And, they probably did something to the ECU map/timing as well....

 

Using the usual 12% drivetrain loss, your 177wHP approximates 201.1 crank HP, not 212

 

any pictures of this bigger intercooler??

 

Is the 12% drivetrain loss a fairly well-documented guideline in the MINI community? Is that for the automatic transmission, the five-speed, or the six-speed? Is there a difference between cars with the LSD and those with the open differential?

A 12% loss seems a little low, but none of my experience is MINI-specific. Getting 177 WHP from 212 flywheel HP is a 16.5% loss, which still sounds pretty reasonable to me.

12% drivetrain loss is what's agreed on by the MINI community. for the 6-speed manual. However the agreed 12% drivetrain loss i think might be because the 170 hp of the stock MCS is perhaps an understatement. I wonder if anyone has done that process with dynos that calculates mechanical drag (drivetrain loss) by letting the wheels slow down with the clutch in....

actually, this leads me to believe that perhaps the MCSs have 180-190 hp, because if you've ever seen a dyno readout of a JCW car, they tend to get around 175-180 whp. Maybe the 12% is being too conservative...

 

i was quoted 20% losses .

 

it is low 20% is what i was told .and no it was'nt a mustang . they said on a mustang it would've been way higher but we digress in other words(who cares?) what i want to know is ; will i get more oomph from the get go with the dfic? or are we talking just less heat soak over stock? if it's the latter then how can the gp make this 218 hp claimed based solely on an intercooler? defence rests.

 

^^^ I hope the 20% loss is accurate, because that means my '05 JCW put out 228 HP!

 

Based on injector duty cycles and an educated deduction in Brake Specific Fuel Consumption [BSFC], the 12% drivetrain loss figure seems reasonably close to accurate.

Beyond that, using the same figure at least gives all of us a level ground to Bench Race! LOL

 

see there you go . jcw claims 210 so i would think a modified s would meet this easily . it depends on the type of dyno i gather .

 

the important thing is going back to the same one and doing better . no ? see heat soak is not a worry to a daily commute if traffic's moving. so why waste the money ? unless it's better from the get.

 

I don't worry about it, I put on a water cooled intercooler. No power loss do to heat. My dyno shop said there is a 27% loss with and automatic. Mine is putting out 190 at the wheels.

 

if you achieve a lesser pressure drop across the IC assuming equal variables, you'll gain power. If you achieve a better thermal efficiency assuming equal variables, you'll gain power. ICs are a specific compromise of both

All ICs heat soak, no matter how big they are. Just a question of how long it takes to saturate and how long it takes to recover once saturated.

Bang for buck is fairly crap with ICs. But once you get a pulley i think that a bigger IC is a good idea.

 

sweet ,what are your mods?

 

okay that sums it up .

 

Exactly.

If there is a drop in presure you need to make it up with a lot more dense air. The IC is a benny & fairly new to an SC ( a nice touch from BMW ). It would be interesting to see the GP IC core & know what, if any, presure drop there is.
