Whoever said that must not have any first hand experiance with the S/C.

You could do the Rotrex, and not need to deal with all the custom fabrication the turbo will require. But you lose the S/C whine, and are pricey. Look into RMW for more details/prices.

 

^If you're referring to me then you're right, I don't have any experience with the Sprintex, it was just an example. But the real point I was trying to make is that he could just do bolt-ons and tuning and have a very quick car.

 

I still think that with the power he is looking for that he needs to talk to Ben (BigShow) over on MT to get the skinny. Those guys have all spent money on various items and with the power that he is looking to make he needs to hear from them before he starts spending money.

 

Before spending any money the OP needs to weigh all the options. You dont just build a bad @$$ car off of impulse, you need a plan.

He is already on the right track, joining the boards. He just needs to do a whole lot of research, and planing. Talk with multiple manufacturers, tuners, suppliers, and people who have done what you want to do. Best thing you can possibly do when entering a build of this caliber, is to get educated.

 

That was my point. Those guys have done and are doing what he wants to do and have tried the various bits and pieces. So they can at least get him started with some solid information on where to begin. I may not like the lot of those guys but I respect the fact that they have done their homework.

Add to that the tuners (you and the others) can weigh in to help him as well.

We agree, don't spend a dime until you have a well laid out path and understand the cost driving it.

 

You should talk to Tüls, but it looks like he hasn't been active here in quite a while. He was part of the team that built the Fireball MINI way back in '06. His personal MINI (Hal) had a similar turbo setup and was good for 400-450HP. I remember him telling me one time that the stock bottom end is good for that, but you'll need to work out the Turbo, plumbing, and a good ECU tune.

Here's his engine bay:

 

thats one of the reasons im asking everywhere like crazy cuz i wanna know which will be better for me like a said the money is no problem i just wanna know which would have better results

 

i still havent find out why ppl are so scared or intimidated to go twin charged i havent get A solid answer of why i shouldnt do it they just tell me dont do it i believe if i go with the right tunning and right parts there should not be any problems im i wrong???

 

If you go the S/C route you can leave the internals alone, spend less money and get close to 300whp with the right combination of parts, but you'll prob. need to be on the bottle.

If you go the turbo only route it will be more expensive, but you'll be able to surpass 300 or even 400.

Twincharged Is ok to do with stock internals, you can get to 350 or so, but honestly it won't cost that much more to just go the turbo route and have much more potential. Also something to think about with twincharging, tuls himself told me that as much fun as it was because of the amount of instant hp & torque, 1st and most of 2nd gear were useless, with fwd cars that are as light as these turbo lag is a good thing when it comes to traction. Not to mention turbo only is easier on the driveline. (word around the forums is much over 350 or so and you're going to start breaking things anyway.)

Honestly like someone said earlier, you'd be suprised how fast a true 300whp mini is, personally I'd put a 300hp mini up against a 400hp awd subie anytime except off the line.

 

the reason people dont do twincharge anymore is because:

there are less moving parts with only doing one or the other
there is less heat transfer
tuning is hard.
And you get more efficient hp with choosing turbo only or a bigger supercharger only.

that is the main reasons that i have found

 

Let me put it this way. I could explain to you why you shouldn't bang your head against a wall, but if you've never felt pain, you wouldn't understand. I'm not afraid of banging my head against a wall, but given my experience, I don't think it's a good idea.
I watched Tuls, a very accomplished tuner, work for hours at an event trying to fix air leaks and various other problems (after having it installed for a while.) There is barely enough room for the SC under the bonnet, much less a turbo and all the associated plumbing.
Yes, if you had all the right parts, there would not be any problems. The problem is developing the right parts. Parts exist (or might), but thus far anyone who has tried using those parts has determined that while it sounds like a great idea, in practice it doesn't work so good.
So by all means, give it a shot, and if you discover the parts and tuning that make twincharging work for you, let us know!

 

Simple, cost. There is no "kit" that you can easily install so everything will need to be fabricated. It isn't going to be cheap to go the route you are thinking of going. Thus most people don't do it. The ones that have spent serious money to do it. You scoffed at 15K but you may very well spend near that trying to do what you want to do.
