When was the last time any of you put ur boxers on the wrong way?
I would bet that the above is more prone to happen then one sitting in HIGH boost instead of LOW....
most guys here spend 10 minutes warming up the car... then another 2 minutes cooling off the car... why then would any of us make a mistake of being in the wrong boost setting?
If you don't respect the motor and use appropriate fuel with boost YOU DO NOT DESERVE TO DRIVE THIS CAR NOR ANY OTHER TURBOCHARGED CAR.
I would not give this car with a EBC to a high school kid that's for sure....
just my opinion guys.... from experience.
markski

PS. Im not saying that this approach is superior to others... just different...
You can also blow your motor by downshifting from 5th to 2nd at high speed and there is nothing to stop you, so I agree with Markski.

I want to do a 0 to 300 KM and 100 to 300 KM...

Once you raise the boost and assuming you can get good traction you should be will into the 5's!

Not completly true, we can use a BC that the AEM,motec,autronic and etc controls, not a exernal one as you mean

SMR,
I have seen many 1000 HP conversion cars from Supras to vipers... and for some reason they all if not most of them had a external Boost controller...
my friend Marco who ran mid8s in his supra(2 years ago) and drove it the night clubs with me has one for example... and he is on AEM.
my point was that that is one way of doing it not the ONLY way... IM by far not an expert in this Im only sharing what I have seen...

Correct you can, but they rarely work as well as an external BC at high boost levels. At least in the Supra community, no ones relies on the Motec or AEM to control boost when running 7's. For a street car, I'm sure it would work fine for lower boost levels.

But back to the point between relying on either a BC or a Flashloader, I personally see no difference? Both approaches require a manual 5 second mental and physical input from the driver if and when they change fuels. Every car I know that runs different boost levels for different conditions needs some type of manual input from the driver. Like Markski said, if you can't remember to turn the boost down in certain situations, you should be driving a stock car with a warranty

Mark that a great run congrats!! Have you tried it in 4th not shifting? that would be a nice comparison with DMK's machine! It should shave a few off your time. I would love to see 60-130 on Ohio GT2's also...tom

In general terms, I am still not sure what that shiftless run achieves, this is not the way you would drive it on the street, nor the way you would race someone from a rolling 20mph, nor the way magazines test the cars, basically you will never be using your car this way.
A 2 shift 6.4s 60-130mph is certainly much more relevant than a "no shift" run, and it includes almost a 1 second shift time in the 6.4s. That being said, out of curiosity, it might be fun to know.

Tom,
I did but starting at 40 mph in 4th on gt35rs doesnt do... I tried.
I did it in 2 shifts in substandard temps and with the boost controller OFF...
meaning that it runs on spring alone... and they are .8 bard springs on TAIL 44 mm WGs...
mark

Im sure it'll take off like a bat with 1.5bars on a nice day even with the 35r's.

You are so right, there is alot of ways of doing it..Im just sugesting a few of them...Most customers i do like a external BC on the Japs turbo cars, but on the Porsche that have and super inteligent BC in the motronic i lke it to control things

I do this all the time and there is no problem with motec or other BC, same as extrenal BC... Using it in the EMS can give you some nice featers and there is alot more going on then dragracing, when thing should hold toghter for like 7 sec you can have and diffrent approch to things

Yes your correct, but Maybe Im wrong, it was agreed that it didin't matter How but the fastest time would count! Scott? Just currious because DMK had his fastest with no shifts....tom
