Hello everyone. I have a 03 R53 with around 58k miles. It currently has a 15% pulley unknown brand that was on the car when I bought it 10k miles ago. Car been great to me. The car also has Alta intake. My goal is to have daily driver200 whp. I dont know where am sitting now but I got to do 10.008 @ 74 mph on the 1/8 with passenger, almost full tank of gas and extremely bald tires. I know that does not tell you hp but thats where am at acceleration wise.

I was considering exhaust, obx header, water/methanol injection and the smoother intake tubing. According to alta, I will see some gain there. I have no plans on doing anything internal to the motor so no heads or pistons or anyhting like that.... maybe if ill consider something, might put a cam but doubt it. Dont know if a intercooler upgrade for the money is worth it. Maybe I could get 200 whp some other ways.. thats why I need you guys opinion.

This is my car below.




This is my other one

 

200whp isn't hard, We get that pretty easy with adding an exhaust and header, or cam with our ECU tunes all the time.

 

4ag FTW!!!

 

Thanks! Its alright. No torque but the sound of the ITBs 165 flywheel horse power is like no other.

 

I have that much amount of horsepower with my mods listed below with a dyno graph included in my gallery.

 

Nice looking car there Just remember that all dynos are different. 200whp on one dyno may be 180whp on another. There are people here that say they have 200whp with a pulley and cat-back only You will at least need all you have, a cam and then get a good custom tune, then you will be close

 

Are remote tunes a good option?

 

no

 

Why??? No

 

Contrary to what hh posted, here is a satisfied customer of an RMW remote tune, https://www.northamericanmotoring.co...-tune-wow.html.

Here is a thread with a bunch of info on remote tunes, https://www.northamericanmotoring.co...-from-rmw.html.

Good luck.

 

Here we go again!

 

just a few thought before this gets too heated.....
IMO the problem with remote tunes is support. If you have a local guy who does tunes, get it done locally (it might not be the ultimate tune...but I bet it will be pretty good). That way if a tune goes bad, or you have a problem, you will not be stuck having to buy a re-flash from the dealer to get the car drivable till you can get the car re-tuned. (good bye 500+ tune, and 100+ for the dealer flash)...sure you might need some dino time, but hopeful the correction will be less costly than the initial....returning customer...hopefully.
Tunes are wonderful things....but they are not very permant unless you have the tool to reflash your own car.....just think, you bring your car to the dealer for an issues that you cannot figure out......the shop, to do what they normally do, reflashes your car to the most recent software (gives them a baseline starting point, and eliminates the possibility that it is a software problem)....some will refuse to work on a car unless they can do this. Now your 500+ tune is gone. If you have a somewhat local guy....you can maybe get him to refash it for a small fee. If the guy that did the tune also does some of the mechanical work on your car....even better!! Cuts down on the chances of loosing a signifigant amount of money...it is more than just a guy who does tunes while traveling. If you endup with the tool to do the remote tunes, so you can re-flash your stored tune, even better, and it might not be so bad. Not sure how most people do remote tunes, but there are pitfalls both ways.

 

All of this^^^.

 

Does anybody know if JAN's tool can restore your factory tune...and then go back to the custom when needed? it does seem like a neat system that helps to avoid some of the pitfalls of tuning.

Still not for the faint of heart.....but closer to being "user friendly".

 

Yes, you can restore your factory tune...and then go back to the custom when needed. You can hold 3 maps, 1st for factory, 2nd and 3rd for custom map.

 

I got 203whp out of my car with just intake, pulley, and exhaust. Not every car is that strong, but it is still easily obtainable.

 

stong car, must have been a wednesday built...

as for me...bak in the supercharged days I made 160whp with GIAC, 15% Pulley, intake and custom exhaust... either a monday or friday built...

Later down the road removed the GIAC software then got the Mynes tune and made 185whp...then added a header and made 195whp..

 

My sig line has my info just click the link - 204 at wheels

 

Im also putting 203 to the wheels, see my mods in my sig.

 

Recognizing there is a great variation in both "stock" cars and how modifications interact with both existing and other mod parts, it's very hard to create the shopping list or recipe for 200whp. However, from my (nearly) 5 years of experience with my car and other modified Minis, there are a few generalizations that I believe hold true:
1. Most common modifications to a Mini don't do much for WHP except for the supercharger pulley reduction. CAI, headers, catbacks produce very minimal increases.
2. You can be pretty sure of getting over 200WHP with a cam. All other methods have much lower probability of reaching that goal.
3. A good day on a friendly dyno can make you smile for a long time: any day on a dyno biatch and you'll never tell anyone what you got.
4. Many modifications are marginal at best, and prolly just a nice waste of money. Hence think about them before doing them--for example, a red MSD coil pack looks cool, but it does absolutely nothing for the car.
5. A Mini is not a drag car, and (despite the obvious exceptions, and there are only a handful) expecting it to be one is missing the point: it's a great handling, fun car. HP is never going to be its forte. Find a track where all you need is 100HP, but great handling, and you will beat most cars there. You will hardly ever use your HP.

Good luck. That's a nice looking car.
