I could get you some phone numbers. The $50K/hr might set you back though

Thanks again Matt

 

Thank you Matt.....

It's always great to see your baby take flight after months of testing
both through computer modeling and then finally a product to do physical testing on our favorite car the MINI....

The DFIC has become an overnight superstar in our arsenal of parts to make the MINI the best it can be, by allowing all the parts that make the MINI go faster, Go really fast

Thanks again Matt for showing all of us some real numbers.

Just to keep the debate lively and motivate this thread a little.
I've posted numbers that good for my GRS as well.
Different conditions though. As noted in my posts I usually did steady state testing since that's the easiest condition to replicate.

 

Thanks for posts Matt.....

 

thanks matt.....
your hard work is much appreciated

 

As always Matt,
Very useful and informative! your hard work is appreciated

 

Thanks Matt.

 

I somehow think I posted my "numbers" in another DFIC thread. The data-logging that I did was with the CarChip E/X which unfortunatly pulls data at only 5 second intervals, at least with the older versions...

I was however able to note lower peak IATs, and feel most telling, was that the peak IATs for my improved GRS happened at WOT, max speed. On the DFIC, I saw the temp jump just as bit after WOT, then go downward as the WOT run continued with increased speed. Neat to see...

Matt, thanks for the more thorough testing and analysis!

 

If the DFIC, compared to stock has about 0.5 PSI more pressure drop and the thermal efficiency is 71% vs. 64% (stock) how much should that change the Charge density and power? Also is it possible to quantify heat soak recovery times compared to stock? Thanks

 

because the thermal efficiency is really dependant on a lot of variables, most notably car speed, RPM and engine load. The first gives the volume of cooling air, the last two the volume of air going into the motor.

If you look at some of Andy's posts, he found stock TEs of some where in the 60s at redline in second, but as high as the high 80s cruising....

Dr O - So, if you had to rate all the IC's that you've tested, regardless of price which one would you most want on your car for daily spirited driving? Least?

 

So, is everyone in shock? 410 posts and finally a TE of 71% and things go quiet? Seems to me, as owner of DFIC#023, it's time to start talking about getting more cool/cold air into the IC and out (thanks, MSFITOY!)
More numbers are needed, of course, but the first numbers show high pressure drop and low relative TE, compared to the stock IC (something like >1psi drop, and only +7%age points gain in TE).
Nobody who has a DFIC has reported anything but amazing PoPo (to quote Hans Stuck) dyno results, so is this all placebo effect? I'd hate to think so--otherwise my DFIC is a grand's worth of bling, and I don't even have the polished one!
I'll confess I was expecting TEs of 90+%! The pressure drop doesnt bother me if I know the air charge is substantially cooler than with other ICs, but the Doctor's first numbers don't show this.
cheers,

 

I tried this in Post# 403.

Good luck

 

I think we are waiting for more TE testing under a variety of conditions other than redline in 2nd. Am I right Dr. O? There were a zillion posts before the data results! Don't be shy - Let's talk. The GRS with the M7 scoop showed about 5% more air (5% more power?) over stock and this has better TE than the GRS so are we talking > 5% over stock. My car dynos at about 180 WHP and I would love 9 more whp and better heat soak recovery.

 

insufficient data and eroneous conclusions are "blood brothers" my car runs stronger with the DFIC than the Alta or stock

 

Keep in mind that pressure drop has two main components, one of which is temperature drop, so the pressure drop should only worry you if the temperature doesn't significantly change.

 

Will, Is Matt's testing done? I thought that there was going to be more TE testing under different conditions. I have a DFIC on order and am particulaly interested in heat soak recovery - any info on this? Thanks

 

If you mean my GRS it isn't an M7 scoop. Joel's scoop does work very well though.
TE averaged ~5% better over numerous different test scenarios.

 

I'm sure there'll be more. More data certainly exists, we'll see what he provides.

 

Yep.
It is a holiday weekend so lets stop breathing down Matt's neck for a day

 

....unless we are breathing cold air under high pressure...everyone have a great weekend.

 

and I've got some ideas on heat soak recovery testing, but nothing final. Right now my car is in parts all over my garage (problems with a SC swap, job from hell for no appearent reason), so I can't ever drive until I get another SC pulley and put it all back together.

Matt

 

What's going on here? Why is Matt responsible for all these answers?
I hope he's getting paid.

 

Matt is not responsible..... he said he would and is making good..... We are fotunate that Matt is so generous with us at NAM and i have thanked him publically many times......

Thanks again Matt

 

My point exactly....
