Here is an auto that has a filter on pump gas using the same setup, with two different maps. One for daily and the longevity of the stock automatic transmission and one for a more aggressive map.

Still the same fuel, just timing was removed :tiphat:

Yeah. They don’t publish or test that case. I already asked awhile back.

My custom designed intake with filter outflows a turbo guard. I’m hitting about 15 psi at only 6600 RPM.

Please see above

LOL, come on. You expect us to believe that with nothing to back it up.

Hence my post asking to see his dyno logs. :tup:

Senna-F1 12-20-2019 09:56 PM

Check the air to air intake options thread guys. Good lord. I’m not gonna post everything in three different threads. Eugene is the tuner, he’s seen my logs too. The boost logs are posted. We haven’t even begun to tune wot yet and there may or may not ever be a dyno. We’re doing remote tuning obviously, and that usually doesn’t include any dyno runs. But yeah, check the thread. Last time I’ll mention it. :)

I know. Unbelievable right? I’m very happy with it so far, but I still have more design and work to do.

To be fair it may be reading a bit more boost just like mine is. My omni 4 bar map sensor logs didn't quite match up with the dyno's boost reference. Dyno showed peak boost at 10.5-11psi yet map sensor swears it's closer to 13psi.

Yea agreed. Similar thing happened to mine. MAP reading was 14ish but gauge shows only 13ish. :driving:

I have 2 MAP sensors, and they both read the same thing.

For the rest of you, not you DrBacon:

Lets take a look at what Topgunz, Aaron himself, said about a design that was smaller in area than my design, and had a smaller air filter. The same design some of you on here not believing me actually liked! :) Turtle64b's design.

Turtleb64's quote: "Topz says that I should be getting 15-16 psi with my setup (he's seen more results from his kit than I have, so I trust him on this)."

Did you read that?

So I create an even larger opening, use ALL of that area, slap on a huge air filter and 6" velocity stack, and report 14.1-14.6 initially, look at and post the logs of 14.9, and everyone just shakes their head in disbelief. :ugh2:

So who is it really that you don't believe guys? Aaron? who looked at pictures of a more restrictive design and said thats good for 15-16 psi?

Or me? who opened up things even further, put a HUGE air filter on the end, and then posted the ECUTEK logs? Eugene also said I'm flowing so much, that my fuel setup with 485 pump, S1.SE FRS, and 1050x injectors is at 80% duty cycle with no room for E85. So even if my 2 MAP sensors are reading incorrect, my injectors are maxed trying to keep the A:F ratio on target. I'm *NOT* running rich at 80% duty.

:yum:

Sorry Nik, I've tried hard to get folks on the correct thread.

TopgunZ 12-21-2019 07:04 AM

We all know the struggle to squeeze boost out of these setups if you want a properly filtered setup. Yet we all see 10 to 11 psi on ours with the K&N filter with a pulley that pulls 2psi more than this car above with just an 8psi pulley but it is hitting 11.6psi. So if you put the 9psi pulley on you should see 13.6 psi with the K&N!

Anyone have an idea how this phenomenon is occurring here only?

So my original setup with filter made 12.76 psi with one map sensor and .86 bar on my 2nd map sensor. Essentially the same. I had mentioned this to you in another thread and asked about your thoughts on it. Eugene said it might be the cam timing. But in working with the filter later, I realized the small K&N has a larger flange opening than the SC and so comes with a silicone piece to fill the gap. At the time I thought maybe the installer did that, so I left it off and put the small filter on again. For maybe other reasons, like the filter had become a bit crushed, I was making now only 10 psi. Is it possible that gap piece wasn’t completely closed at the end and let more air in than normal? And if so, is it possible others are doing similar, and not getting a really tight seal at the filter? Just my thoughts. This may be complete non-sense as I had a coolant leak and so had to remove all the piping and put it back. I had some slight boost leaks after all that which may have contributed to the only 10 psi after.

You right brah. When my car was finally running correctly for the first time thanks to Adel, he was able to pull ~13.3 psi on the vehicle. And that's with 91 octane, brand new coned K&N air filter, 9 psi pulley, 3.0" SC direct pulley and 3.2" jackshaft SC pulley.

I don't inow where everybody is coming up with these boost numbers. When my car had the stock K&N filter and the 9 lb pulley, it made a little less than 11 psi.

When I went to the 2.85 sc pulley with the K&N filter it made 12.88.

When I went with the 3.47 jackshaft and 3.00 sc pulley and turbo guard screen it made 16.4.

All confirmed on the dyno.

Making a little less than 11 is the norm with the 9 lb pulley and this kit on over a hundred kits. How 11.6 on the 8lb is happening is a mystery.
