I am curious of your gains as well. I have recently bought the following pieces and have yet to install them (thanks Jag!)

EVO intake piping

RSS Plenum
EVO TB
EVO Upgraded Y-pipe

After talking with Markski I am unsure if I am actually going to put all this stuff in or go with the blow thru system. IS there anyone else here with 24/18's using this hardware? What kind of gains were seen?

 

This is a copy of a post made by 996ttalot over on Pistonheads

Okay so now for the interesting stuff. Neil sent me before and after runs, same conditions (IATs), same stretch of road. The only difference was that he had more weight in the second run, which is a shame because that affects performance, but you can see for yourself that the car is quicker. If we look at the figures below I will explain more [The left side is PRECONVERSION so the right side is POSTCONVERSION. Neil done several runs, so I have checked each to compare, but they are consistent.



1) Each entry is a timestamp in durametrics.
2) Neil was at full throttle on each - I could see this from the throttle position parameter.
3) He was in the same gear
4) He was on no boost at 2100 revs for each of the above, and then floored the throttle, which was shown by the increase in TPS.

Results
1. He is spooling quicker - the boost comes in quicker
2. The boost is higher - in some places by around 0.86 psi - okay that doesn't seem like a lot, but bear in mine the change that has been done her - the pipe and intercoolers.
3. He was quicker through the same gear
4. His AFRs are better. He is running less rich in places. It seems that the DME has adapted, and recognising the greater airflow. This would make sense.
5. His IAT at WOT (7200 rpm) is 6 degress less. His starting position is less by 3 degrees, same AT.
6. Difficult to judge the IATs, because until you go over 150, you really cannot see if they help to stop timing being pulled.

 

But you also probably have ICs that cost more then most guys spend on a total tuning kit... so thats hard to compare... also, too many variables to be a one to one comparison different turbos alone will change the results... different boost, tune, etc,.
Ics cores are very important... and it looks like those in the pic are entry level $1500 units.. ( nothing wrong but its the truth) and when you compare them to $10K cores then we really don't have much to talk about... not trying to sound ****y but true...
You really needed to do the same comparison on stock ICs... then it would give us the delta... you need to compare within your car before and after... not your car against someone else's car...
please don't get me wrong not trying to sound snobby...

I have used both the EVO inlet pipes with 2.5" IC's, 2.5" Y-Pipe with 75mm TB and RSS plenum AND the Protomotive blow thru MAF system. I feel there is no perceivable difference between the two at the K24/18G level with dual fuel pumps and larger injectors. It's more a matter of which do you prefer from an ownership standpoint. The blow thru MAF drives differently.

 

Ari,

I was in Markski's car last night with a Ford MAF and I didnt experience any of that. The car drove smooth and the RPM's didn’t jump on start up (I have the stock maf and on cold starts my RPMs jump up and down for about 10 seconds) You may have other issues with the car if that is what your experiencing.

Mark- Why dont you do a video of the car. Lets do some pulls too for the hell of it

 

My personal car with 1000rwhp does not buck down nor have a odd idle. It has the ford maf. We sell the intake systems with the ford maf and if the car has no boost/vacuum leaks and is installed properly coupled with a custom tune most of the clients do not have problems. Many high hp car run this set up. Nothing new.
I'll take some video clips and show you guys proof on one of my kits I put together. Sorry but I will proove the doubters wrong and as Vince said to me that he did not even know I was running the ford maf. It really comes down to the install and fine tuning. Just because one or two members had a less then expected experience does not mean that all such kits do the same... it really comes down to the install and fine tuning... mind you the video I will post is the start up file and was not even fine tuned for idle...
BTW, it's not like there are 10 other options... nor is the first option( stock maf) any safer running 600+rwhp then a ford maf... imagine running a car with what we call "blind calibration" when your past the stock maf readings...... that's what your doing on a stock maf that reads only 1500kg/hr @5volts vs ours that reads 3800kg/hr.
videos soon ....

No ari i dont im just on standard actuators by the look of them, but i havent tested them. If i was to fit one bar gates would it affect the tune, or is it just a case of fit them and set the crack pressure.

 

No offence taken but there are so many intercoolers out there but we never see the results how good they are,just wanted to compare.
My IC's are build in Belgium for a big German tuner and always tested on my car to see the results.There is so mutch info on turbochargers but never for intercoolers so I just wanted to compare that's all....

 

Guys,

You missed the point of the comparison - it was before and after the install of the ICs. So he had the standard ones in, we ran the tests, and then he installed the aftermarket ones. So the ones he has in there now are working better. Whether they will be good enough at 150mph + is another question.

Regarding the other topic, I have the Ford MAF, full blow thru system, k24/20g and it idles like a baby. I have the aircon switched on permanently. If i switch the aircon off, then it will idle a little more rough. Todd K told me to do that. So I totally agree what Mark is saying, if everything is set up right, then the FORD MAF works fine.

BTW, I did think looking at the technical manuals, that the aircon (until it is switched to low mode by the DME - e.g. full on driving, has a pipe that links to the fuel cooler, so unless I am wrong, having the aircon on keeps the fuel in check. Well that is what it looks like to me from the diagrams. All my performance figs were achieved with aircon switched on.

And BTW, we are running 12 cars tomorrow, all at various tunes etc, and some are std. I am datalogging the proto 5inch i/cs up to 200mph. So it will be interesting to see how they perform above 150.

 

I just took these today before it started to rain...
here is a start up on our big kit with the after market maf that is in question... you be the judge if it is drivable or not...

Here is our ski800GT set up at start up on warm motor with our aftermarket maf....

As ken says the tests were done back to back on the same section of road and the same temps , so show a real world change from the pipes and coolers.

Ken good luck for tomorrow, if i had knew it was so soon i may have came down to watch.

 

Ken,
Good luck and be safe! I will be watching for your PBox data with keen interest!!!
See if you can better that 6.6s...

I should be able to even on normal fuel it is just every time I have tried, I have a load of extra weight in the car! Not tomorrow though. Also have 50 litres of 104 race gas , which gives me another 5 points on the stuff I have been running.

Looking forward to 0-186 (300kph) times (hoping for less than 25secs), and I might do one top speed run. The straight is 2 miles long, so I probably have 1.4 miles or so before braking.

Just a bummer that my rear diff is currently on it's way out (just starting making the noise during the last week). We changed the oil (which was black and burnt) but the diff needs to be rebuilt.

Not sure how fast I will take her, but she'll be good for 200 that for sure.

 

We'll find out very soon mate... best get some zzzz's, early start !!
