Psi-Fi and Eric of Helix:
I have been waiting for update of your Turbo/supercharged Mini S fo a while now. Any new details?:smile:

 

Psi-Fi - that's exactly what I was going to suggest! Twin charge this baby! Apparently like Psi-Fi said, they're going to adjust the max boost for each gear. I can't wait - I'm pretty sure I'm going to do this to my next MINI...Wahoo!

But back to the original post, the MCS is not a dragster. Now in modded form (pulley, intake, exhaust and maybe ECU) it can be a fairly powerful fairly fast car, but a rocket it is not. But the big problem as has been mentioned is off the line. But for regular driving, the MCS is geared quite well for high speeds so many cars that would beat us pretty good in the 1/4 mile we could take on the highway. There's also loads of cars that'll beat us by 1.0-1.5secs 0-60 yet 60-90 we'd beat no problem. Add to that the MINI's ability in the twisties and we really have a phenomenal little sports car for the money, IMO.

 

Then again from what I understand from reading chasis design books, suspensions that you'd want on a dragster are significantly different than what you'd want on a car for twisties.

It would take about 50hp over stock, LSD, sticky tires, no heavy options like sunroof, lightened interior (maybe), and deeper gearing.

I am curious to see what some have done with either the new for '05 deeper geared trans or anyone running some sort of aftermarket gearing. The MCS is very long legged for a drag car, but is great in road courses.

 

We fully intend to have this on my car and tuned in the next 10-14 days. Erics car will get the treatment a few days after mine. We have all the custom pieces/parts in production right now and we are waiting on 1 part in particular so we can get the turbos on the cars. The turbo we chose for this application has incredible efficiency at our targeted power/boost levels so as not to cause too much heat rise in the system pre-supercharger. The kit will come fully tuned via our piggback ecu w Garrett Ball bearing turbo,530cc injectors,water/alcohol injection, Electronic Boost Control/boost gauge,BOV,Stainless downpipe with high flow cat,cast exhaust manifold,Custom silicone charge pipe and all hardware and oil/coolant lines and fittings needed for install. please express any interest to Helix as they will be handling sales and install of this turbo kit.

we will post pics,data,and some video as soon as we get the systems on our cars.

 

Setting up the boost schedule for low and high boost will greatly aid low speed acceleration but it will also lessen driveline strain due to torque multiplication of the transmission in the lower gears as well. Our goal with any system is to safely make power for both the engine and driveline.

 

Psi-Fi: sounds good seems getting closer.:smile:
A few small questions. Do you have to use 530cc injectors? Sems very large, why not some where in the range of mid 400cc. Will run rich if when the turbo is controlled by your piggyback controller to reduce boost if cutomer wants.
Aren't you planning to use an oversized intercooler to keep temps down?
As mentioned I am interested in the HELIX/SPI-Fi new install. I will be one of the first to have a Lsd in the Miin S cabrio. This would be perfect for a new Mini Varient to show its stuff. Good luck and happy-Landing.
One reason for the oversized intercoolercooler is the temp range in South Florida.

 

Who? When? How?

PSI-FI, thanks for posting your times. Have you dyno'd with those mods?

 

But he got in the 13s without the Nitrous. So....if you have 210-220 at the wheels...the car should be capable to get into the very high 13s. I guess you have to be good enough driver.

Alex

 

By the way, even Jeff did not get under a 2.1 sixty foot time. You can add to his mods the Evotech and Quaife too...

I will not discount the importance of a skilled driver...ever.


By the way, I think I lost 20% of my hearing to the Top Fuelers yesterday. How about a 4.68 @ 314.64!!

 

I agree, but I said 2.2 seconds, not 2.1 seconds. And it appears that his car makes 258whp with 50shot nitrous, which means the car w/o nitrous is probably in the 210hp range at the wheels. So I guess it can be done based off of his timeslips, dyno sheet, and people corroborating his story.

Just takes a lot of work and skill, which I have always agreed with.

 

2.1 w/ nitrous.

 

You're suppose to wear earplugs!:smile:

 

I believe the intercooler is the same. They are using the stock pulley on the supercharger and the turbo doesn't cause the heat build-up that a high-boost supercharger causes (as with 15-19% pullies). The stock intercooler should work fine.

 

"WHAT?"







I got caught off guard. I had my 2 and 4 year old sons with me. They had their plugs, but I forgot mine in the stroller bag under the grandstands. I didn't have time or ability to carry them down with me (I was alone, no wife) and get mine. I was too busy covering their ears!
....oh, and then Bob Motz's friggin' jet truck!

look here:

we flowed the stock intercooler and it flows very well for the size constraints we have to deal with. We are going to use a water/alcohol injection in our kit totally controlled by our piggyback computer. this coupled with the factory intercooler(we could add in a 3rd jet for intercooler sprayer) should more than suffice in this situation. As I stated previously we are using a very efficient turbo in this application and we are going to cool the pre S/C inlet as well as the post intercooler charges off with the water injection. I will tune a street setting as well as a race setting that will take advantage of the extra octane in race fuel(more aggressive timing and fuel map). As far as the injector sizing, as of right now I have tuned in the 420cc injectors and in my opinion they are not enough for what I want to accomplish with this car.

 

Anyone that knows me knows that I "loathe" dyno's but... according to a horsepower calculator my car with the aforementioned mods at a weight of approx 2900lbs running a trap speed of 96.6 has about 204whp. In this race I ran a PT Cruiser turbo I tuned. I caught him sleeping at the line and held him off on the big end. These little modded coopers can hold their own w a stock SRT-4/WRX once they get into 3rd-4th gear.

 

Ah, don't worry about your hearing. I understand it takes years for the effects to show up and by then you won't want to hear what's going on!

Nice video....nothing like standing next to a jet turbine and having it leave under full thrust..

 

Psi-Fi, for people with a reduction sized pulley, would we need to go back to stock size?

 

the tuning will be done for a stock size pulley. running a good amount of efficient cfm/boost into the supercharger running at stock speed will provide the lowest ait's. if you want more power simply push more pre S/C boost. Im going from my 19% back to stock this week.

 

I managed to peel off a datalogged 1/4 mile run. I know it's not an "official" timeslip, but I think the acceleration graph makes it valid-enough for comparision:



According to the datalogger:
0-60 MPH: 5.8 sec.
1/8 Mile: 9.2 sec. @ 81.0 MPH
1/4 Mile: 14.1 sec. @ 100.4 MPH
Unfortunately, no 60ft. time.
LOL, notice zero traction in 1st gear. I upshifted early to 2nd.

Cheers,
Ryan
P.S. Yes the ground was level!

 

The MINI wasn't built to go fast in a straight line... I mean, that's JMHO, but you'd be better off seeking out another form of motorsports that involved some corners - either the road course or autocrossing...

I noticed you're in Dallas?

 

Lets just say your run was official. That's very respectable! I'm hoping for similar results with my 05 JCW, after a little help.

 

It amazes me how many people are misinformed about the reaction time at the dragstrip.

Reaction Time (the time it takes for you to get the car off the beam at the starting line once the light turns green) is NOT a factor in your ET, nor your 60ft time. Those of you that have made "60 passes" and are still thinking the reaction time is a part of your 14 second timeslip, please listen up.


Otherwise, this is a good thread, keep it going. I'm a drag racing junkie and was curious as to my new Mini's performance. Looks like I have quite a bit of modding to do before it's presentable in 1320 fashion.

 

Your 10 to 14 days are WAY up LOL. Whats the latest on this project ?
