My car is alive!
i saw so many comments about weak power,carbon deposit,etc and i was begining to believe those comments especially in hot summer days with 40 degres celsius when the car was struglle to build speed but ...
yesterday when i was channging oil and filters i discovered a broken (squeze) vacuum,that one that operate the airbox powerflap.I replaced and today i wanted to see if my car is improved.i have 116.000 km on the clock( cca 72500 miles) and i believe is a little laisy compare to my first tests from 2010 (45,000 miless)
A perfect day for that : 15 degrees celsius(60 fahrenheit), dry asphalt,
those are the results 1/4 mile in 13,01/ 13,03/ 13,02 / 13,02 and 0-62 mph 4,75/4.77/4.76/4.75 Trap speed cca 108 mph.
I AM VERY HAPPY with those results cause i was begining to think the car is to old and i have to sold her.
i have milltek non resonatev,valved with 100 cells cats but for my surprise i have an original map sw080 and i think i could say it is a stock car.
I will clean the valves( never cleaned before! and i will remap with a MRC soft).And i will make again some tests cause i dont believe in dyno.Just tests on real roads.
I have 2 engine fault codes : P0421 WARM UP CATALYST(O2 sensor i think) and P3019 exhaust flap valve n321 (the milltek fault code)
A very good thing - the clutch is original and i alwais launch the car with 4500 drop clutch(i think for maybe 50 times) and the only weak simptom is the pedal not returning immediatly(i think is the pressure plate or slave cylinder).I have one for spare cause sell Sachs(and many other brands)
So i have a stock performance car with 116,000 km on the clock that are running better that the factory claims - 0-100 in 4.8 and 1/4 mile in 13,2.Mine is 4,75 and 13.In 24 degrees i was achieving cca 13,18 drag times but that ones was with a very dirty air filter,old oil and defective vacuum hose.
In my previous posts i posted some slightly eronated times(the testing device wasnt mounted perfect and the trap speeds seems a little unrealistic.
All this performance facts and fact that i-ve just repainted,new wheels,new michelin tyres,new headlights,new projectors,new led rear lights,new window,etc make me say MY CAR IS ALIVE AGAIN.
I think i will keepit another 1 or 2 year cause im refalling in love with her.
My car is alive again!
Re: My car is alive again!
Just goes to show how a vacuum leak can effect these engines. Many have experienced vacuum leaks, glad you got it rectified.
What country are/was you testing in?

Money can't buy you love, but it can buy you a well sorted racecar
Re: My car is alive again!
1. great to hear you're excited about the car again. Good job finding the problem with the vac.
2. what testing device are you using for the 0-60 and 1/4 mile data? Pbox? Gtech? Etc. Post up the rest of the info like 60' times etc if you have it. Always fun to look at actual performance data. I too don't care much for the dyno...I'm much more interested in proving how fast the car is moving than how well ink sticks to paper.
3. launching at 4500 rpm is maybe a little violent for the stock clutch. I'd be more inclined to try launching off 3500 rpm.
4. that P0421 code could be:
a) defective O2 sensor. This will be sensor 2...the one AFTER the catalytic converter...the one farthest from the engine (and easiest to replace).
b) your car is telling you the milltek HFC are not doing enough...it's a catalyst efficiency code. Check to see if the cat on that side is still in good shape. This is a PITA though because it usually involves removal of the downpipe.
