Mishimoto Induction Tube

[DarkestHour]

What logs? This is all I have from them. It was a Time Attack classification dyno run so it was just hook up (DynaPak with no tail pipe sniffer, just OBD hook up) run, swap intake tube, run and then unhook. I can ask the dyno operator for any other info. The print out is I have on hand.

So how did you know the timing was reduced?

Question to anyone with this hose...does your on board computer read A/F weird after install? It seems to bounce around a lot and at WOT, won't go down for a bit.

That said, I didn't unhook the battery yet (maybe resets ECU?)

Nope. I've posted my logs in a thread I made not too long ago comparing Mishimito to JLT to stock.

I am going off what the dyno operator said. The car was having issues as soon as he was getting into the throttle for the run. He managed to get the ECU to not have load issues earlier in the 3rd and forth runs, as seen in the graph where it looks like there is a huge gain. That is why he told me that at 4k the graphs come back to actual data that is not being affected by the ECU removing timing, again what I remember him saying which could be incorrect, but I do remember 100% that at 4k and up all the runs are on par. This was not a tuning session so I did not expect anything further than numbers and a graph. I emailed the Dyno Operator to get some clarification.

The heavy load and steady RPM at the beginning of the pull is what he said caused the data to be off up until 4k. There was no saved data or logging. That is just from what he knows and his experience.

I'm no dyno expert. So I can't tell from your posts if the problem below 4k was from the dyno or operator not doing what's optimal to get numbers below 4k or from some problem with the tube? A mod that causes problems with a load below 4k would not be good.

Guy I got my Mishimoto tube from did back-to-backs with Airaid full CAI and this with stock box and K&N filter. Picked up max of 30 whp with the Mishi tube and stock box over the Airaid, and I recall about 15 at peak power. [MENTION=31127]ALUSA[/MENTION] you have the dyno sheets?

[MENTION=13955]ryant601[/MENTION], mine bounced a little bit on the first start-up after installing. Since then, no. It's been very smooth.

How/why would the Mishimoto tube have such large gains over the Airaid tube?

The runs after the tube was installed are actually better ( less load issue ) compared to the stock. As it was just for TA classification, was not something he tried to overcome as he knew what was going on and we were just looking at max power. It was just a basic $60 three pulls run that he let me do four runs and swap a part midway so I was happy. I wasn't looking to post damning data or a smoking gun to buy this part, just trying to get as much data out as possible as I have not seen a bone stock no tune back to back with this tube. I will be going back after I install my PP1 as well.

Not a real problem. My car feels quite a bit stronger between 3k-6k with the tube.

The Airaid tube has less volume between MAF and throttle body compared to stock and the Mishimoto tube. If you read Mishimoto's development thread on this part, they found that they lost power when they did a nearly constant cross-section tube compared to stock, and saw gains after adding the buldge, which replaces the resonator chamber. That chamber deals with the wave harmonics in the intake system, like the when the air hits a closed intake valve that it was heading towards and bounces back.

I'll try and watch/video mine to see if that happens. But I don't have anything to compare it to since I have not looked at that while driving. I might put the stock tube back on to get a direct compare. Do by chance know what it does with the stock tube connected?

I don't, but I feel like I'd notice it and I don't recall seeing it with the stock tube.

Really? It'd be interesting to see what the gains are after the fuel trims have settled. I wonder if these gains shown by the guy you bought the Mishi from and the OP are related to that?

In other words, comparing an Airaid that's been on the car for many miles and then swapping to a Mishi right on the dyno is not an apples-to-apples comparison.

Same if it was the other way around (guy with a Mishi on for many miles swapping to an Airaid on the dyno).

Ideally, I'd suggest another Mishi dyno after a few hundred miles and a handful of starts but I know dyno's cost $.

excuse my ignorance, but how does a simple tube swap produce that much extra power on a stock tune?

Same question with a CAI? Can it really be pushing that much extra air into the engine?

edit: a few extra HP/torque is expected, but over 6 seems strange to me.

As much as I'd love to believe it, I think it too sounds optimistic but I've expressed my thoughts on possibly why a few posts up.

I understand and agree with you. I will be doing the Ford Power Pack 1 and going back to the dyno again. I know that will be a dyno with the PP1 already installed as I want to put miles on it before I dyno. There is a local guy doing the Airaid tube, I might try and get him to throw my Mishi on to see if he gets different results.
