Cool! By how much?

Btw.
Please run some before/after tests if you ever decide to get an IC.

I made the meeasurements on the week-end when I was logging data. Unfortunately I didn't log the IAT's as I was monitoring too many things at the time. But I can do some logs and make some graphs to see. It gets much cooler than stock at super-high speeds. I went to speed governor (155mph) a few times and I was watching the monitor and it really stays cooler after 120. Maybe there is air coming in from somewhere at those speeds. I don't know. But it's certainly not hotter than stock once in motion.

M&M has the pre and post dynos, which is very nice.
Btw. I was talking about Deck, you about M&M, I guess..

[ThomasMartin]

Well guys my dyno is the perfect base line to compare, im going to buy the cones tomorrow and than ill dyno and compare numbers to standard intake all dynos will be done with the hood closed

A dynojet, V2 + painted reflectors . It's going to be a baseline for DP+exhaust that comes next month. If I can find stuff locally I'll test this intake after the baseline. It's going to be hard to do empirically though, even if I do the best I can think which is to drive around like a mad man and pull right onto the dyno with the stock box run, then rip it off fast and put the dual cone on, there will still be adaption and such getting in the way of solid results.


M&M these IATs are charge air temps right? I'm talking about pre turbo temps, believe it or not it does make an important difference, maybe not so much on final HP, but on overall stress.

Ok, that's all nice, but how about in somewhat more typical speeds?
Driving in the city and stopping for the red lights every now and then might not get you to be the quickest from the lights

Yeah at normal speeds (up to 100mph) it isn't much cooler. Can't say its really hotter either. I mean your turbos suck from the intake and then it goes through the intercooler anyway. So if its a few deg hotter does it really matter? Its gonna' get cooled anyway. I can't believe that travelling at 80mph, the air is trapped there. Here's some pics BTW, this is a copy of the Terry Ghetto intake, which I guess is a copy of Shiv's prototype intake. Note the stock duct from the grille leading directly onto the cones. I'm not finished yet, I will add another pipe from behind the left hand side brake duct and channel cold air to the centre of the cones with that as well.

Hi ,i am planning to do something similar, will you take the cold air from the inside of th e wheelhouse as vip is doing, or have you found another place?

WOW, did you pit that together yourself? Was it difficult? You should post a DIY if it provides 20-25hp to the V2.

So with what you saying is that with an aa exede and and intake we can make 370whp?or even with a juice box?we already know the intakes make power up top,people bought the v2s to make that power with no other mods.

I'm sorry but I haven't even seen this kind of dyno before. Let alone dyno'd a 335 on one, at 5500' altitude. Have you? I suspect not. So how can u be so sure that an Xede or v1 can make the same power? I don't understand why you are expressing yourself with such vehemence when you are so plainly wrong with your conclusions.

FWIW, a car running at 5500' will be very close to the limits of its turbo capacity. What this means is that v2 will not be worth as much (over v1) as it is on a car running closer to sea level. This is not hard to understand. If you want, I can explain in greater depth. Seriously, I will. Just let me know.

I took it while we had the engine on the dyno for analysis.





Stole it from here

Wow, that was some serious spanking here! I would love to read your explanations, as I learned a lot reading your posts over the past year. But, truth be told, I would love even more you using that time to create a PROcede for the Porsche 955 TT!

o-cha, would be very interested to read your finding following the engine dyno run.

What was the output? How does it equate to the power loss figures that are bandied about, i.e. 12.8% for the manuals and 15% for the Autos.

Looks like a fascinating session.

Shiv,
I'm assuming you meant 5500 ft above sea level, not rpms?


To the OP, good numbers! I made 346 or 349whp (forget) on the original stock air filter w/ 21k miles on it w NO FAN on a dynojet......so the power is there. Surprising thing was after 3 runs the oil temp didnt get that high, 240ish w/ no air flow. I guess a few more runs would have cooked it a bit more. Stupid I know, but I was in a hurry.

[M&M]

I logged some IATS during a 10 minute period of peak hour traffic. Mostly sitting at the lights and idling. The ambient today was 22 deg Celcius. The car idles about 8 deg above ambient. It did creep up 5 degrees during the normal traffic routine, but it did the same with the stock airbox.

I will do some load testing at speeds when I get a chance but I know what will be good. The idling test is the best one for testing the cones. Reason being that at low or idling speed there is no airflow over the intercooler. So the IAT reading is basically the same as the temp pre-intercooler. Once you get up to speed the intercooler starts operating efficiently and the hot air is going to get cooled anyway. So testing at idle is effectively testing the temps of the air coming from the cones.

Keep starring at the post and all will become clear I actually think A4 might have missed the joke too.

Like I said in that "other" forum. 8 celsius (about 50 F) over a cold ambient is pretty high, can't really make any conclusions with other similar data to compare it to. But if it were 8 degrees over these ambients http://www.e90post.com/forums/showpo...6&postcount=19
you would be running hotter at idle then WOT.

Yea you can't really compare the two, nor should you really compare the post IC temps unless your goal is final HP. If it is your golden. If your worried about your turbos your some other color then golden.


I'll test it out though with a temp probe to get actual intake temps between the two in a week or so though.
