Alan Posted January 21, 2019 Report Share Posted January 21, 2019 Hello, Here is the tune file for my 2003 MINI Cooper S that I race in GTS with NASA (National Auto Sport Association) and BMW Club Racing. https://drive.google.com/file/d/1JVhjpeVhWHSubJpOya5x56rsSomkDuUw/view?usp=sharing It is a stock MINI engine with 50 thousands over 9.3 to 1 compression pistons. Stock cam advanced 10 degrees on a Endyn big valve head. The SC is running the stock pulley producing 10 psi of boost max. It is a power to weight class so we attempt to get a flat HP curve, thus the unusually timing curve. Questions / Suggestions welcome. I am the tuner and still learning.

1320MINI Posted February 1, 2019 Report Share Posted February 1, 2019 Hi Alan, what power you trying to achieve? to get the torque up but keep the power low you could fit a camshaft with more lift and duration,then run a restrictor, This way you'll get more power and torque down low and stop it making loads up top.

Alan Posted February 1, 2019 Author Report Share Posted February 1, 2019 Thanks for the feedback! The dyno curves above give a 140 HP "average" using the GTS calculator. I can make 148 HP "average" and still be in GTS1. I have just fitted the KAVS JCW pulley in place of the stock size pulley. This should get me to at least the 148 HP "average". I'll know for sure by mid March. What cam are you thinking about? I was thinking about replacing the stock cam with Cat Cams 257 / 259 (street) cam. This is supposed to add low and midrange power. I was planning on restricting max HP via the E-throttle map. You mentioned using a restrictor instead? Thanks again! Quote Link to comment Share on other sites More sharing options...
1320MINI Posted February 2, 2019 Report Share Posted February 2, 2019 With a 11% pulley you'll probably pick up 10-15hp easy, You talking about the "461" Catcam? Down low it will make the same as a "469". Throttle is a good idea to restrict the air flow. Alan 1 Quote Link to comment Share on other sites More sharing options...
Alan Posted February 2, 2019 Author Report Share Posted February 2, 2019 Yes, I am talking about the 1302461 Catcam. And thanks for confirming throttle is good for restricting air flow. Quote Link to comment Share on other sites More sharing options...
Alan Posted April 24, 2019 Author Report Share Posted April 24, 2019 The MINI is now running in GTS2 with NASA & BMW. I recently replaced the Eaton M45 with the TVS 900 running the 70 mm pulley. I will shortly receive the 65 mm and 60 mm pulleys which I will use to get the car to the top of the GTS2 power/weight.
