Topgunz - air to air upgrade

Pauly Z · 04-10-2016, 09:33 AM

I'm more worried about performance with this supercharger, not the sound or smell.

Cats will most likely fail, clog your exhaust and go boom

So you are running test pipes?

I had HFC'S and switched out to TP's.....ur EGT'S will go up as ur F.I. so I just decided to go with the TP's to rule out burning them up.....There's not that much difference in sound between HFC'S and resonated TP's....but since smell and sound don't bother u go for the TP'S FTW!!!!...There's more to gain using them.

Check my sig. MD Arts

Cats are probably ok for 9psi or under. Better safe than sorry.

Topgun, do you have any video's yet?

Not yet, what are you looking for?

My car is currently down from needing to fit up some brackets.

Topz. ...at this point any Vids will do....even at idle with a couple of revs.....

Maybe like a quick drive with a under hood tour.

StillenZ84 · 04-10-2016, 05:15 PM

Im running Berk test pipes. Definitely recommend them over cats like Top said cats can potentially cause major damage.

One thing I forgot to mention is that the MAF voltage readings were exactly the same from side to side. This is important for proper idle. That means the Y pipe is split perfect so both sides, both throttle bodies are receiving the same amount of air.

I forgot to tell the tuner to take a screenshot or I should have snapped a pic of the laptop with my phone of the Maf readings. I am going to redyno and I will do it then.

On this note....since the MAF's are post blower and right before the Throttle Chambers then we're getting accurate AIT's now versus the Stillen set up which is pre-blower right? Were u able to log ur AIT'S on the dyno run?

I was reading on the variances between Dyno Dynamics and DynoJets and it seems that DD's always read lower than the DJ's. I think we use DJ's here as the standard. That is what I last used for my car in Denver when I hit 490whp. Here on the DD I hit 527 but it seems all research says to add 10% to 15% to convert to DJ numbers. If that's the case and we use the median of 12.5% then my car made 593whp! Which actually feels more accurate on the street. The car seems much faster than the 37whp difference in numbers from DJ to DD. It feels closer to that 75-100 mark. I did make 4psi more.

Using the supra calculator for dyno differences I made 627whp but I don't think it is that high. Toyota Supra MKIV : MKIV Specifications

If you google "Dyno Dynamics to Dynojet calculator" you get tons of the same research that they read at least 10% lower.

Anyone have real world experiences with the differences on the Dynos?

So i've had the opposite occur,

I hit 622 on a dyno dynamics but 598 on the dynojet

I don't really think theres a universal thumb of law that can apply, too many variables.

The local dyno is called "The Heartbreaker" because it is a Dyno Dynamics and reads low compared to others.
