Well, I was predicting lower in the 16's in my head, but I was going with the optomistic 120hp, at the wheels. If you do an 18.5, you'd better have taken a nap in the middle . Changing your reaction time won't change the ET, the timer does not start until you move. What was your 60'?

 

Hey guys - just ran my stock '03 MCS up at New England Dragway, just for fun, to see how she'd do - at first I hit a few mid to low 16's and was pretty disappointed, but got her to 15.7's by the end of the night.

I'm bone stock aside from a K&N drop in filter, removed airbox shield, running stock GY runflats on s-lites, no passengers/excess cargo (for the lower runs).

My BIGGEST complaint - that clutch got heatsoaked FAST and became useless in 1st and second. WHAT gives? It seems perfectly fine now, and has always had a very low grab point, but after a few runs the thing just slipped like a banana. Is this common? Do I have to replace it if I plan on doing this ever again? It was obnoxious!

 

Wow, that's a strange set of symptoms. In my experience, a bad clutch has the symptoms of making it very hard to shift, and slipping in the upper gears, not the lower ones. Are you sure you weren't smoking the tires? I thought I trashed my clutch on a run my first time out, but found I was just a bit exuberant and smoking the tires.

 

Nope - DEFINITELY slipping clutch, because it would eventually catch and I'd feel the wheel start to spin, hop a little, and catch. And to boot, my grab point is definitely higher than it used to be - I always could get it to grab just a little bit off the floor, now it's about halfway up the pedal travel. I had hoped after letting it cool off it'd go back to normal, but no luck. Tried the 2nd to 5th shift on a steep hill, grabs and holds fine, but again, the grab point is definitely higher. Looks like it cost me some of the life of my clutch :(

 

It's been a couple years, but I pulled off a new personal best last night. 13.892 @99.89

Still running 15% pulley, Alta CAI, Magnaflow Cat-Back
I've added a RMW tune, now shifting at 7400 rpm.
I bolted up my old hard hankook autox tires (225/45/15). Looking at the 60', you can see that they don't hook much better than run flats :-P
My car weights 2610 without driver.

Maiden voyage down the 1320 last night.

'08 R56 with DDM street intake. Otherwise bone stock down to the run flat tires.

weather was PERFECT. 63 degrees, low humidity

R/T: .120
60': 2.39
330: 6.52
1/8: 9.95
mph: 72.04
1000: 12.88
1/4: 15.39
mph: 89.62

Good baseline.

 

Capital Raceway 9/19 Temp 66 deg. R56 MCSa JCW Stage 1
60ft 2.19
1/8 9.298 @76.84 mph
1/4 14.443
mph 95.79

 

What??? What kind of setup are you running to get that kind of time? That's M3 territory. I want that.

 

Went and found a calculator that didn't require a subscription, and here's where it ball parked me. (something like this I would say is only ever an estimation, I expect actual running to be different, much as the difference in estimating WHP and BHP on an assumed conversion factor)

16.090 @ 89.6
became
15.423 @ 92.884 MPH


The track scale put the MINI's weight with less than 1/4 tank of gas at 2935lbs

 

Wow, is 2935 with or without driver? I assume with, my loaded MCSC with all kinds of crap bolted to it is 2820 at 1/4 tank without driver.

 

great driving........
just think .......the record is only 8tenths away

 

Nice time Jason, you had that sucker hooked all the way thats for sure.

Is the track more of a muscle car test and tune

 

its totally obvious some tracks are faster than others, just like dyno's read differently. So comparing numbers from one track to the other is silly in my opinion. It's well documented the ABF drag car has ALWAYS clocked the fastest times at Englishtown, even with over 100 less hp

 

Summit Motorsports Park (used to be called Norwalk Raceway Park), is supposed to be one of the better tracks in the US (NHRA Sanctioned, used to be a IHRA track), it has a beautiful racing surface, they hold some major events there and the track prep is pretty good for weds night bracket racing, when I ran my best. My car seems to run about the same at the other local track which is no where near as nice of a track (full of cracks and patches, many fast cars won't run past the 1/8th). Assuming a decent launch, the biggest variables with my car seem to be ambient air temp and if I've iced the intercooler prior to the run. With the tracks being at similar altitude, I don't think I'm fast enough to see much difference from one track to another.

Cheers Jason, I'll mark that one on the map as If I move to the USA.....................

Cant believe you didn't come back with, its the driver of course Thats got be the time to beat with your list of mods.

How much do you weigh out of intrest? what hub horsepower or wheel horsepower have you seen on the dyno?

 

Hahaha...all driver, yeah, thats it!!! I think I'm a pretty decent driver, but seeing as I only make it to the drag strip 2 or 3 times a year, I know I still have room for improvement.

My car is about 2610 lbs plus roughly 185 lbs for me. When Jan tuned my car on a dynapack, it made 199.6 hp to the hubs. Am I correct assuming that "hub" hp and "wheel" hp are going to be roughly the same? Maybe wheel HP just a slight bit lower due to energy loss from sidewall deflection?

Jason

 

that's exactly why I said great driving.... maybe Paul will get it someday that the cars making 250whp-285whp are spinning so bad that its pointless on street tires

 

............maybe before they ban the nails in Jan will get that hp = mph, then again I think not.

You've got a set of MT on rims not doing nothing lend them out mind you there probably hard as arizona rocks by now

 

I'm surprised that it read that low to be honest at 2795lbs to run 99.89 you must have 250 + at the fly, I think the President of Brazil was walking raround the factory wheb they made your engine, enjoy a 1 in a million

 

maybe someday you will figure out hooking up the tires means more than hp
Then again........... Maybe not

 

Wow I didn't know that, thats where I must of gone wrong with Jeffs

TOO MUCH GRIP ON BLOCK TREAD TIRES

 

Paul,

How much injector do you need for 250+hp at the crank? This guys appear to be stock.

 

you won't be sending anyone into space with Pauls calculations
Finding the local 7 eleven might be difficult

 

We usually see more hp with stock injectors over 380s as they usually lean it out, I have seen 250bhp+ with 330cc, you just wouldn't want to be doing on 4 mile roadcourse for 30 laps

Its a bit like all the dyno numbers floating about, anybody else weighing the same as Jason's with the same mods is going to be pissed that they cant get near his times.

Its trying to work out why there are these freaks out there and how we can capture what they have and transfer it to other cars.

One of our customers with an 06 went 14.2 at 101 with a JCW 4-2-1 header JCW cat back and 15% Alta V2, GRS IC and Alta V2 CAI, and like Jason he could drive and it weighed 2700 with him in it (2.3s 60s)

 

I forgot to note them above, but I added the JCW 380cc injectors with my tune. I doubt the injectors themselves are adding any HP, but I wanted the safety margin for the extened WOT seen at track days.
