Hey guys,

just seeking some advice, when I hit second gear in full throttle, around maybe 4500-6000 rpm there is a huge flat spot. I can feel the car not wanting to go any harder, however after 6000 rpm it picks up again :S...... its not the sparks or coild as when i got my full 3inch zorst done, i had to do coils and sparks due to miss fire issues. The mods I have are:

3inch turbo back, Splitfire Coils, Apexi Pod. When i got the car dynod you can see the flat spot massively as the power dips off then increases to my peak power. The car is running 11psi with no boost controller, but i believe that also cause im running no cat.

Im thinking maybe the stock side mount cooler doesnt like that much boost maybe? Anyone else had the problem and been able to resolve it? I can post the dyno sheet if anyone thinks it will help,

cheers

Rich and Retard- Use the search function heaps of info.

In short if you wish to keep that boost level you will need to either remap the standard ECU or upgrade it.

      Jacks that fit under GTR lips that can reach the subframe?

      By MBS206 · Posted

      For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!

      Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
