Takeda intakes and Scangauge info

tbss370z · 10-17-2009, 09:11 AM

I installed the intake a few months ago and did get the same negative results on the dyno like several people here have noted. I ordered some universal aluminium heat shields and noticed lowered oil temps. I have not tested it on the dyno to see if there are any improved gains. I'll try to upload pictures when I get a chance.

I suspected the IAT's would be up there a bit... Any open element filter is going to suffer the same fate. Unfortunately we do not know the Temp differential that results in significant timing changes...

My Insulated and shielded filters run about 5 degrees over ambient when cruising at a steady rate, so that will tell you the differences in the shielding (Plus I have the fang vents, which should bring your temps down a bit)

On the A/F, I haven't set mine up yet for that, but anytime you are in "Closed loop" the MAF and 02's will make every attempt to keep fueling in the stochiometric range of 14.7. You'll see that number bounce around a lot as small sampling corrections are made. These can also be seen in the short term fuel corrections if you've set it up to read them. Go WOT (Open loop) and you will see the true A/F tuning. Ideal will be around 12.5 but chances are it will be richer than that (lower number). You can also set the scan gauge to indicate when it goes from Closed to Open loop

Thanks for the feedback modshack. A/F ratio looks to be steady at about 14.5 but Long term fuel correction is around -5 same for short term fuel correction. I am no expert, but take that this means I am still running rich. I can also hear it, there always is a nice popping in the exhaust when I shift down at higher RPM.

I wonder if Takeda will ever come out with the heat shields that they promised Amplified. I guess we'll have to wait until after SEMA...

But I will most likely change to Stillen G3 after this winter anyway

I don't know what Heat heats are, but lowering oil temps has no effect on intake temps. I wouldn't waste my money on another dyno run...

Can you post your dyno results and pics of the heatshields? I am really curious!
