The only thing I don't really like about the traction control on the Mini is how sensitive it is. If I take a corner pretty fast and accelerate hard out of it, my tires might start to spin just a little bit because of the acceleration. Then the traction control turns on and apply's braking to the wheels that are loosing traction. Of course, this slows you down a LOT because it'll leave the brakes on for a good 15 - 20 feet, meanwhile I've got my foot to the floor, but I'm not going anywhere and I'm loosing seconds off of my time. I'm just glad I can turn it off at the switch of a button. It's for my own good I guess.

 

they should make a performance chip for that, like they do with ecus.

 

I'll just stick with turning it off when I'm autocrossing. I've gotten used to driving it so I'm getting better at giving it just enough throttle to pull me out of the corner quickly without losing traction.

ice box, no doubt. a cool air intake is very important with an SC. the cooler the air, the less detonation. and the JRSC has no IC, so a cool air is a great idea.

 

Oh yes you do...

(BTW, that's some funny ****, remmy. LMAO.)

 

Just to let you all know, i have a Jackson Racing supercharger and turbo on my 99 d16y7 and at 11psi on the supercharger i only produced 156Hp and with 11 psi on the turbo i produced 192 so you do the math the supercharger just gets.
way to hot!!! and the intercooler is the extreme advantage and just to let you all know the supercharger has lag too unless you rev it up to 2200 rpm and drop it, other wise the lag from dead to go is less on the turbo then on the supercharger.

 

man, this thread was getting quite and everyone was happy where it was going to end... then you post that crap and get it going again with your 2nd post. A s/c is instant boost, what part of INSTANT doesnt make sense? The second I get on the pedal, my boost needle shoots up to full boost. less lag on a turbo, ok... welcome to hcf.com I guess.

The reason your blower gets so hot is because you dont know what you're doing. You cant run 11 lbs. of boost on that thing without some sort of cooling system (water injection), so all you're doing is actually losing HP because of the added heat.

 

First of all, I'd like to see a pic of your dual boost setup. Secondly, Polo makes a good point. I can get away with 11psi from a SC on my SSEi, as it was designed for it. You have done alot of work on your car, but you're not quite there for 11psi yet, and should have an intercooler. I can't see you running more than 8-9psi without boost stacking and KR out the ying-yang.

And I'll back Polo up on the SC lag thing. No offense, bud, but that's just hilarious. If you see a lag, it's because you have so much KR, your ECU is pulling timing. There is no boost lag. If there is, it's measured in MILI-seconds.

I'd like to see your dyno sheets to determine exactly what's wrong. Your transition in boost from SC to Turbo should be well-defined in the logs, and I hope you had AFR data logging during your dyno run, too.

Another often-overlooked aspect of SCing and Turbo use is that most people look only at the PEAK hp. Many overlook torque, which is the major point of it all. Not only that, but don't look just at the peak value. How flat is the curve? At what rpm did your hp and tq peak at BEFORE the SC or turbo, and where does it peak now? How long does it hold peak before dropping off? How many rpm's are at 90% of peak tq with the SC? It's how the curve LOOKS, for 3 things....horsepower, torque, and AFR.

For example, if I had a civic that I popped a JRSC on, and my hp (theoretically) went from 100hp to only 120, then I took the SC off, and put a turbo on, and my peak went from 100hp to 130, the turbo may not necessarily be better if the peak with the SC happened 1000 rpms LOWER. The same applies to torque.

There's something very wrong with your setup. Let's see if we can figure it out with your dyno numbers (you've obviously run it on a dyno), and perhaps a data-logging scan during a dyno or street run.

 

i know im a little late, but if you have a turbo, especially a small one, when it starts to spool aren't you at max boost? thus creating more power at 3500 than you would with a SC?
