How much power do I need?

[Fat Felix]

Hey everyone.. I'm sure you guys get questions like these all the time..And I did try searching, but have no idea what words to search for.

But I was wondering what I need to be fast as a stock 6spd 350z in a roll on..

Or how about a stock LS1 F-body? I know those are pretty darn quick, from a roll or launch..

My CA currently has a t28 from a GTiR, d/p, 3" catback, fmic, 450cc injectors, 255 walbro, z32 maf, and ecu chip.

Current boost is 0.9 bar.

Oh ya, what's max boost on stock internals and HG?

Thanks,Felix

Max boost on stocks... ALOT with proper tuning.

honestly u need to get your car tuned cuz u should be able to keep up w/ the 350 w/ those mods (assuming w/ tuning they net around 230-250 whp and a 350z probly puts down around the same to the wheels (250ish)and w/ that fuel system u could be running more boost tahn you are also (i dont know when that turbo starts blowin hot air....im sure sumone will chime in soon lol

thats my .02

yep, 350Z's are slow (stock)... you should be all over a Z with the level of tune you're at. Something isn't right with your setup if you're loosing.

HP aside, your car is around 600 lbs. less than the competition you list. Downshift and wave.

get a 3" downpipe, boost up to 17psi or so. wave goodbye.

I haven't actually raced any of these cars, since I just recently got my car..So this question is just hypothetical.

And I already do have a 3" d/p.. I am still currently running the stock s13 cat, which I plan on changing soon.

So what's max boost the stock motor can handle?And what's max boost my turbo is efficient for?

As for tuning, my ecu is chipped, but I am not sure what it's actualy doing(my fuel cut is at 7400 rpm though). I also do believe that I'm running pretty rich due to crappy gas mileage and pretty strong gasoline smell at start up(is that accurate?) What type of tuning do you guys recommend? Something like SAFC or getting my ecu redone? I was planning on getting a FPR to play with the aF reatio a little bit as well. Will ecu tuning take care of the need for a FPR?

Oh ya, what else do I need to be keeping up with the LS1 F-bodies?

THANKS!

You can't really ask "What is the max boost the stock motor can handle?" as that can't really be answered. That will vary for every turbo, every ECU tune, and a million other factors. As for your other question, that one I can answer, and it is about 1 Bar (14.7psi), maybe a little more.
