Have a look at the comparisons done by Rjohnson on my site...

Scroll down to bottom and you will see his findings.

I knew there was a reason I wanted one.

I don't understand the graph. Am I reading it wrong where I see the Scotty2 with 50-100* higher EGT except at 51psi?

The scotty2 is hotter than the FIPK unless the turbo is being overdriven?

brandon, the cornfused one.

Scotty

Brandon, I think you are correct. He mentioned to me that he pegged the gauge with the FIPK and not with the scotty II and hole. He also mentioned his turbo limit.
I have seen similar results with a lot of power and not enough turbo.

His last line says this...

-I am clearly pumping super heated air at WOT. Not as bad as many, but it is obviously my most limiting factor. No air system can overcome that condition, but the Scotty II does it better than any other I have tried.

Thinking about this more, I had DD 3's, EZ and TST drag with a B1 KS and never had those kind of temps. Is that turbo on that truck the same as the early B1 Kwik Spools?
The temps seem to be about 100 higher then what I was getting.

Hmmm.. was this done with the UNI or the aFe element? I wonder if that would make a difference. They're a different type of filter.. oiled foam vs oiled gauze?

Good catch Brandon...didn't notice that myself, about temps being lower with the FIPK II at lower boost settings. It was done with a Uni Filter.

I take lower boost setting readings with a grain of salt for two reasons...

1-As you probably know, it's difficult to hold an exact boost setting at partial throttle...at least it is for my turbo. Quickly scanning from boost - EGT's - back to boost, could be off +/- 5 psi!

2- Seems obvious to me that "cruise" throttle (hp) at 40 psi boost, for example, would give very different (lower) egt readings than WOT, wastegated to 40 psi.
I will be testing this theory within 2 weeks, with an external wastegate, mainly to re-evaluate TIP's.

Scotty - Rod reported several months ago that the KSB-1 had been modified...more open Turbine housing, and had passed the B1-2 in HP rating. Never got solid verification on this? Also, could my temp differences from your KSB-1 readings be due to my auto tranny?...or as Brandon suggests, due to UNI filter?

Has anyone done oil analysis testing for silicon ppm with the UNI filter?........I'm curious on how it compares to the AFE or the FIPK..........

Scotty

I've only had one report to me on the ppm of silicon with a UNI two stage.
It was right in the usual results I got from the aFe, 6ppm. I emailed to get the full report before Christmas and have not got a reply.

I am currently using two single stage UNI filters in my shaker hood and will be doing an oil analysis at the next oil change, which will have 10,000 kilometers on the oil.

Perhaps some manufacturers will post horsepower gains, torque gains, mileage gains etc. I post what I get from the user of the product.

Reports of folks using the UNI have noted unchanged or 40-50 F more reduction then the aFe so this result does seem a bit out of the ordinary.

Scotty,
So correct me if im wrong the hole really only makes about a 50degree difference.

Scotty

In comparison to a stock intake it is much higher. When comparing to other air intakes, the difference is still there but not as much.
I also have this feeling that the particular truck and its components are what is effecting the results of both products.

For example, I was running the stock HX-35 with the DD 3's and TST Comp and my egts where through the roof with the stock air intake. When I put the Scotty Air II on without the hole I saw a total of 150F reduction compared to stock under load. I also netted 225F reduction with the hole open under load. Once I put the B1 Kwik Spool on I saw about the same with normal driving but once I got under load towing or at WOT on a grade empty, the difference was 350F from the stock box. Cool down was faster too. Normal light throttle driving did not net more then 50F but once I had a load on or WOT on a grade, the Scotty Air II showed a better reduction in EGT.

There are several people who have a similar combination of add ons to the truck in question and many of them have switched from the stock box or another aftermarket box and have netted better results.

However, even if its at its max limits on the turbo, the testing at WOT throttle showed it saved at least 150F from the FIPK that pinned the pyro.

Getting another 50F difference at that level is still a good reduction over another aftermarket intake. Getting over 200F reduction compared to a stock box is great.

John P on here has a Scotty Air II and has tried several intakes and had netted better results with the Scotty Air II than any other intake. He has tried them all.

Scotty

on edit:
I should also add that the original Scotty Air just had the cowl inlet, adding the fender inlet netted 50F more reduction.

Awesome!.....Having no experience with UNI filters, I'm glad to here that there is some data suggests the new UNI's are on par with the AFE filters.
