Giiioo Posted April 20, 2012 Author Share Posted April 20, 2012 is walbro 255 ok for that power? maybe fuel dampener is to restricted on N/A fuel system? Quote Link to comment Share on other sites More sharing options...
Nic Posted April 20, 2012 Share Posted April 20, 2012 Probably a silly question but you're using a UK spec ECU as well? Quote Link to comment Share on other sites More sharing options...
Nic Posted April 20, 2012 Share Posted April 20, 2012 is walbro 255 ok for that power? maybe fuel dampener is to restricted on N/A fuel system? The TT and NA use the same stock fuel pumps, the Walbro pump will be fine. Quote Link to comment Share on other sites More sharing options...

Noz Posted April 21, 2012 Share Posted April 21, 2012 BPU is around 400bhp, you must be well over that if your pushing whp. Quote Link to comment Share on other sites More sharing options...
Guigsy Posted April 21, 2012 Share Posted April 21, 2012 yeah. are the auto transmition losses like 70hp? i forget now. so 340 whp is about right. just checked mine made 380 at the fly and 300 at the wheels. so if that 340 is whp your going well.

Giiioo Posted April 21, 2012 Author Share Posted April 21, 2012 Car is manual now w58 Quote Link to comment Share on other sites More sharing options...
Noz Posted April 21, 2012 Share Posted April 21, 2012 I lost 71bhp through my w58 at 373bhp so not really a huge difference. What do you think you car should be running at, without the lean problem? Quote Link to comment Share on other sites More sharing options...
Giiioo Posted April 21, 2012 Author Share Posted April 21, 2012 My friend have supra bpu jap spec, 403whp on same dyno 18psi. He have fuel controller installed, i think it's big diferente 65whp on same boost Quote Link to comment Share on other sites More sharing options...

What do you think you car should be running at, without the lean problem? Gearbox makes no difference on power if it's not auto, at 19 psi boost minimum 360whp without afc and 410 whp with afc.

Giiioo Posted April 21, 2012 Author Share Posted April 21, 2012 Only think i want to realy know is if maf is limited on high boost or n/a fuel dapener is not good for tt fuel system Quote Link to comment Share on other sites More sharing options...
Noz Posted April 21, 2012 Share Posted April 21, 2012 I've never read any fuel limitations with the NA fuel dampener regarding high power NA-T setups, well past what power we are discussing here. From builds I've read they have TT's running 600+ with the stock MAF. This does depend on several other factors though. Could there be an issue with your o2 sensors, have you checked the voltages?

Giiioo Posted April 21, 2012 Author Share Posted April 21, 2012 Factory setup running to rich, it kills power, when you setup fueling, dual intake, fmic, 3.5 inc exhaust and downpipe, good fuel pamp 400whp is no problem with stock turbos Quote Link to comment Share on other sites More sharing options...
