i also have a m-7 coming.any help on mods. would

really help, thanks,doug

 

Well, we are off topic here, but I don't want to start a thread about this.
The M7 scoop is the perfect complement for the Alta IC at this point in time.
I applaud M7 for getting this scoop out as it is truly something that the Mini was in need of. Because of this I tread lightly on making any negative comments about this product
The mods I did to the scoop were something that I personally felt needed to be done to get the most out of it's design. Simply enough, I did a bit of surgery and some fiberglass work to open the final opening, resulting in about 30% more air flow into the IC. More could have been done, but it would have taken too much time and I needed the scoop ready for track day.

 

Any updates on the 19% + 4%?????????????


Alta have you done that testing?

 

At this point, we haven't test this out selves, and i belive everyone that bought the 4% put them on a 15% car. But if anyone is willing to try this and dyno before and after(with some stipulations), we will offer you a very good deal on the pulley.

 

Do you have any of the 4% left? Have you heard back from the 15%+4% installations that indeed there are no clearance issues when running?

 

Yes, we sure do have a couple left. They work just fine on the car, no clearence issues at all! The 2 left are special ones just for people to do some dyno runs with. Let us know!

 

Well, after performing the test here are some highlights:

1) the 4% crank pulley has no clearance issues...fits like a glove.
2) the 19% + 4% combo does create more torque lower in the rpm band, yet loses some at higher rpms.
3) intake temperatures were through the roof. On the first cold run with the combo, temperatures reached 216deg F (6500RPM) after the intercooler. In general, intake temps were 20-30deg higher than the 19% pulley alone.
4) The car experienced knocking on at least two occasions on each run with the combo.
5) Boost pressure was raised a little over 1 PSI on average. (readings were taken at the FPR).

Conclusion:
We are not satisfied with the tests! With such high intake temps, it's difficult to say the what the full potential of this combo can be. We will be revisiting this test soon with a larger TMIC and more fans hovering over the intercooler. Baselines will be redone of course with the stock crank pulley.

Though having a little more lowend is definitely fun on the street, we are not recommending this combo for anyone at this time

A general summary with some graphs can be found on our website here:

Good results! :smile:. But, I'm a bit confused. The numbers on the test seem weird cause you list the mods [basically the helix 13 19% deal with 380cc injectors, pulley, densos, a full alta intake [with hose], and a milltek catback and got 174/169 hp/tq. BUT, your tests on the stock car with full ALTA intake showed like 176/151. Am I missing something? Granted torque is way up, but HP is down, below the otherwise stock car. I gathered that the Mustang dyno was tre reliable, albeit with low numbers? Any thoughts? Thanks in advance! .

 

Kudos to ESE for pushing the limits and providing some excellent feedback. Keep it up!

 

keep it up! good to see an detailed search for results.

Must be the drinking water in PA.

 

Brian,

Consider water injection to help control those intake temperatures. There is a thread on this same forum that has some good information about this option.

Wow! This setup deffinately works. I haven't gotten a chance to dyno before and after yet, however I did go to the drag strip last night. Best time of the night without nitrous was a 9.0 at 79mph. With nitrous I ran an 8.6 at 85mph.

Before I put the 4% crank pulley and TMIC on the best I had run was 9.2's without nitrous and a 8.78 with nitrous.

Sixty foot times were in the 2.2's.

Oh by the way if you like the low end torque of the 19%... Well just come take a ride. The car is so easy to drive with so much torque.

 

Did you notice any of the bad pinging that ESE saw? What kind of software are you running? According to the AF graphs that they posted, you may be doing your engine some real damage. Look at the spikes. Good luck.

 

Nope didn't see any detonation. I am running a bigger intercooler then they are. Hence cooler intake temps. Also when I started spraying I was using high octane race gas just as a precaution.

I am using car chip for data logging.

 

Spillman, Great job and thanks for the feedback. Being that you are running the strip, are you rev'ing past the SC redline? Or do you have a shiftlight set to help you keep the rpms at the SC from biting you. Any reports on the street feeling of this combo? Again, thanks for the feedback.

 

Spillman, are you putting anything away for your rebuild?

 

Actually I am. I am tearing into the motor soon to change the pistons to something stronger. I might do chromoly rods or something like that too. After that I will be going to a two stage nitrous setup and running drag radials. Can anyone say 7 sec Mini?

 

I am going a bit past the supercharger redline between shifts. I am flat shifting so I see the GIAC red line for brief instaces.

On the street it feels almost like driving a tractor off the bottom. In 6th gear going up a hill at 35mph the car still pulls like there is nothing to it. Highway cruising is awesome. Need to get around someone before your exit? Press the gas and watch the speedo jump.

I am amazed that ESE was seeing 220 deg intake temps. I have the Alta TMIC and I have not seen anything above 160. I guess the intercooler makes a huge difference.

 

That's what I'm running, the Alta TMIC. I guess that's the difference in a dyno setup and actually running down the road. Wow, 160F at tops is very good. What about a boost comparison. Do you have that data? Looks like ESE was seeing a couple psi higher, or about 500 rpms sooner depending how you look at it. I don't see any sprayer, external or internal listed in your mods. Or do you use the external water sprayer that comes with the Alta? Thanks for all the public observations. I wish you a sub-7 .

 

Well, after looking into this, I'd have to say that temperature was the culprit here. The day I performed the intake testing, the temperature logged was around 90deg with a humidity reading of 53%. The day the crank pulley tests were performed it was around 75deg with a humidity reading of 43%. Though the deviation is still fairly large, it does explain why the readings were consistent on each of the respective testing days. I also performed twice as many dyno runs with the intake (14) as I did with the crank pulley(6). Cool down periods were also shorter during the intake tests.

Though the Mustang Dyno does factor in outside temperature...I don't think it can possibly account for the inefficient cooling capacity my MINI seems to have at high temps. :smile:

HP readings were higher on the intake tests since readings were taken up to 7000RPM, and the crank pulley tests were taken up to 6500RPM.

Good eye!

 

spillman,
Thanks for you hard work! I would assume 1/8th mile, not 1/4 mile. Have you done 1/4 mile runs with your car?

What boost did you see with your setup?

160 degree air temp is much better, that TMIC is doing the job!

Petrich brings up a good point that everyone should be looking at. Water injection!

QUOTE]

Yes it is 1/8th mile. I would love to go to a 1/4 mile but the 3-4 hour drive is deffinately holding me back.

I am putting out so much boost I threw a check engine light. I believe the factory sensor only reads to about 18.5. Correct me if I am wrong.

I am seeing about 18-19 psi in this summer weather. It should be higher in the winter.

 

Cooling capacity is fine. For a square foot opening, a 60 mph "breeze" moves over 5000 cubic feet per minute of air. So, for the IC, if you estimate the scoop effective opening at 20 square inches, that's abit less than 750 CFM through the IC. That's pretty serious flow!

If you model the grill openings as a square foot, that's over 5000 CFM. That's more than two SPAL 16" electrical fans (if I remember the flows right, I got one a while ago for my Mustang).

IF the mini were cooling capacity limited, then we'd all be overheating. since we're not, you're underfanned!

Build a box and get some fans with the right capacity. I'd go for about 1500 CFM, that will allow for simulation of higher speeds, and bigger scoops. To do it right, get some logger that does an output perportional to RPM, and then have the flow scale with engine speed.

But this also means that you should do something other than a couple industrial fans cooling the radiator. Or take a long time between runs, and run the electric fans off a different power source all the time.....

Just some thoughts...

Matt

 

I don't understand why a tuner out there on the MINI scene doesn't just fabricate a 'wind tunnel' with 1500cfm fan that can direct air directly into the scoop with the hood closed...hey, that's not a bad idea...maybe I could start making it and designate it as the 'MINI dyno standard .' Yes it may be a little expensive, but nothing in this life is free

Cheers,

Henry

 

Here they are. And for all of you that said the intercooler wouldn't make a difference... Today was very humid and hot so the numbers are a little low. The dyno was a dyno jet.

Run.003- 4% Crank+Alta TMIC @ 84 F
