    Tektrader Z32 Hoe, service me baby

    Re: all this and yet you still run a front mount?

    Well NO John.

    Example: R32 TT GTR Twin turbo implemented on an in line 6 with one big intercooler.

    Basically the same as a Z32 but in line positioned

    There is no cross over plenum on this car and each set of 3 cylinders feed the same placed turbo with a balance tube. Works in that !

    What I am gonna do it basically the same.

    Actually all your posts asked questions

    So you didnt seek comment?

    I think not researched at all from the looks of it. You dont seem to know the first thing about the pros and cons and have stated you wont search on the topic so how is it you plan to know anything?

    Some real world results....

    Heres a nice pic. Notice something in this? Look at the corners....
    [​IMG]

    This is an 11 second run on stock turbos.

    Few others for you:

    [​IMG]

    Sebs car, latest was an 11.2 at 128mph. Notice something lacking front centre?

    Gregs car, sidemounts, couldnt get a good picture, 10.19 @ 136mph FULL interior, a/c, the works.

    Rich's car: 10.2 @ 133mph

    [​IMG]

    Ask ANY of the major 300zx yank shops. They all use sidemounts for a very good reason. Having to use a front mount for high HP is just pure myth.

    SMIC Question

    Hi Guys,

    Just wondering were the air go's after going through the stock SMIC's. Does it go to the engine?

    Also has anyone taken the wheel arch panels out to let the air flow out that way?

    All of them have fog Light air ducts...

    That looks crap.. ruin the look of my Z

    :D

    Plus I need my fog lights to FIND ROO's at night.. or ill collect them.

    obviously not enough air flow, and they have to ruin the look of the zed by taking out the fog lights to add some air ducts.

    How funny is the first photo, even got his mirrors folded in !! I guess if

    you're chasing 1/100's of a sec. then everything counts.... :D

    I am more than willing to try at the drag strip though

    do a few runs with my FMIC pull it out and do a few with side mounts, see if I can get better times with Side mounts.

    Hey I tired that once when I was trying to beat Risk's 12.9 sec pass :)

    Didnt help me but.

    Far out... thats the shit.

    I am going to get one.. and Mount it in my SIDE mount locations...

    Good point

    J4Play you obviously don't know who this dude is. In the industry he is regarded as the GURU. There is a story on him in latest Zoom or might be another mag? He is a Guru in his field and I can't think of anyone better in Australia. He lives it literally 7 days a week. It is his profession and full time business for a start as well as extensive research and testing and training on the subject with qualifications in thermo dynamics something and refrigeration etc. He primarily deals in top end stuff only and mainly on very expensive race cars. Mostly intercoolers for drag cars. He made that huge 150mm thick mega dollar intercooler on the yellow show car zed YUMEE. He does raise the point though with me last night about theories and reality does not always follow in relation to intercoolers. He is big on testing where possible although he concluded that results usually follow the theory.
    Yes to do a proper test apples for apples is same car same day, same fuel etc and swap intercoolers or what ever the test is to be is best.
    I can only talk in general from having lots of zeds on our dyno and probably more than the rest of Australia combined for past two years that we have had the dyno and what we have found to date. Generally FMIC's are better at least ours are anyway. It is possible for some FMIC's to be worse than some corner mounts. They do cost lots more especially when you need to get large vented grill to replace the blocked factory panel between head lights as well as a larger radiator. Other disadvantages being a bit heavier as they are larger and also more pipe work, but this is out weighed by power increase and able to cope with hotter temps over close together hard runs on dyno or road or in reality where it really counts at the track.
    Re the cross over air thing, well the engine is a machine and does not know where the air is coming from it is not left hand or right hand air, he he. Balance pipe well there may be a difference but if there is I would think only minor as the pipes are duplicated and if going serious get a balance pipe made between intake pipes. Different intake temps yes probably depending on style of front bar. I have water spray on the lower part of the cooler mainly to help re this as gets less air flow.
    Saying a car does so many rwkw or quarter mile is not conclusive either way, as I often work by the saying, "Good is the enemy of better." A car can run a 10.5 second quarter for example with side mounts but may do better or safer with FMIC. So many variations of features on cars and design of front bars etc etc all generally speaking. Just to raise the point not to hang hat on that fact that because a car does certain time at track or rwkw on dyno does not mean it is the best it could do better or at least longer and safer to engine by keeping inlet temps down.
    As far as I am concerned both are better than factory and as far as what is best well we say FMIC for stock turbo's or larger turbo's FMIC is better but be aware of disadvantages. For BIG HP I say FMIC is much better to needed. Z1 workshop in USA who do some serious Zeds agrees and I think his might have the biggest hp zed in USA at least what I have seen or heard of over 1000rwhp on the bottle though and FMIC and he recommends FMIC for over 700hp as per his site see link below?
    Now I know I keep saying this but I will test both on my zed next week if have the time as engine goes back in prior to our track day and will be tuning and winding it right up. Expect well over 400rwkw with FMIC at least and will measure inlet temps and log on either dyno computer or Autronic or both. Will also compare rwkw. We will also test our current FMIC to PLAZMAMAN's which we will have available soon also. This won't be much power difference without tuning though. We can also measure and compare boost levels as 1 psi will be a decent difference in power. We expect less pressure drop from the Plazmaman intercooler to current. As a general rule 7 c increase or decrease in inlet temps equates to 1% increase or decrease in power. So if with our larger corner mounts even with two big fans inlet temps are say 14 c higher especially after a few runs which is my guess or more then at say 400rwkw this is around 8 rwkw less. Where it really makes a difference though is being able to advanced the timing a few more degrees by having cooler intake temps. This is what makes more than a few rwkw difference. For the track the larger size of FMIC also allows for more stable intake temps so again more power and safer. One hit or two on dyno prob not much difference from good corner mount to good FMIC. Come out to Mr Race Track and lets see.

    How are you going to test you car.......>>

    On the street? Those are the figures I want to see. How does it work on the road? in traffic? in reality? I don't drive on a dyno so the results of tests on one only tell me half the story.

    lol when when people around here start having 700+rwhp cars then

    maybe they can start testing your theory that front mounts are better then. Until then ALL major 300zx shops in the US INCLUDING Z1 state side mounts outperform frontmounts. Just so there is no misunderstanding your post.

    Plus the comment that air crossing the banks makes no difference is very wrong. Not only wrong in theory but PROVEN incorrect that Ive seen, data logged and dynod for myself.

    I'l await some more dyno info from you next week.

    Test Car

    Wizard is getting my old FMIC if willing to be a test pilot and fit our corner mounts then our FMIC? We know his stock corner mounts are no where and waste of time trying to tune it when in last.
    Re the dyno it is a good test in a way as easier to do exact simulation and can measure rwkw as well as intake temps and boost easier, but road yes and also track with lap top.

    Yep, that is what we need.......>>

    A bit of back to back testing on the street over a couple of days. Data on all sorts of temps (inlet, ambient, water etc) along with some power figures and maybe some 0 to 100 runs if anyone has a Gtech or similar. Perhaps then we can finally put this whole arguement to rest. Personally I don't care one way or the other, because I don't like the look of front mounts so wouldn't get one. That is just my personal taste though.

    GOOOOOD QUESTION

    No the air that goes through corner monts mostly hits a wall called splach trays.
    Although the engine bay on a zed is packed a zed with FMIC would still flow better than side mounts as hard to blow into a bottle. The factory vents to help air pass after going through side mounts are very small and not too good but can be improved on.

    Well

    Wonder why Z1 recommend upgrade from the large corner mounts to FMIC for 800 engine hp. Upgrade does that mean better and bigger. Same language so I guess so. They recommend FMIC for big hp cars?? Because side mounts don't cut it or FMIC not needed for lower hp cars which I agree and too costly but can still be better.
    Where do you see or believe " ALL major 300zx shops in the US INCLUDING Z1 state side mounts outperform front mounts" ? I did receive an email a few months back from Russell from Z1 re FMIC and side mounts and basically agreeing with me so?
    If you check the gallery or staff cars in Z1motorsports site you will see Russell's zed in there. Very tough road car in fact they say most powerful road going zed in USA and has FMIC verticle core though. 1050 rwhp.
    I have seen a few zeds on our dyno with stock turbo and lots of other trinkets including our FMIC 270rwkw and proven on track and can't seem to be able to get this with corner mounts at least not yet. So yes disadvantages but also good or better for stock turbo's too just cost too much for most which I understand. I don't know of anyone upgrading from FMIC to corner mounts but the other happens regularly.
    Only 2 10 second zeds in Australia both FMIC. Could do it with corner mounts? But not me thanks.
