pissa. yes, i suppose they are happy in their world of ignorant bliss. or maybe its us who are ignorant?.... hmmm, no, no, its them..
well yes and know The plenum actually doesnt feed the same side of the engine that the turbo is on anyway. A feed through FMIC like i said feeds the same cylinders as the turbo éxtracting power from. Apart from not doing the induction as the engineers óriginally designed. I cant see an issue. Whats different than feeding an in line 6 by doing this? same intention. As i said, I have decided to do this in any case so I will see if there is an issue. If someone would like to tell me WHY this is not OK I am listening. Arguments like "it is just not right" without reasons and facts wont hack it. Why is it not right!!
Sorry I honestly cant be bothered recapping it Feel free to search both here and ttnet. More info than you can ever want. At the end of the day do whatever makes you happy just dont imagine that your getting better performance. In fact you can easily be losing hp/tq and not know it. On my tuning I had a proven loss of something like 80-100rwhp/tq directly from my front mount not to the mention the long term damage running uneven pressures between the banks could of caused.
I care what it looks like, who would buy a Zed unless you cared what things looked like? Don't kid yourself. FMIC for me, looks tough, gets more air flow, and gives me an even better reason to get a nice twin pass radiator for track days (which arrived in the mail yesterday ) So even more bling for me!
Re: Sorry I honestly cant be bothered recapping it This exactly the sort of useless post I was hoping to avoid !! If you couldnt be bothered recapping, why comment with such a long email telling me you cant be bothered ?? :lol: Thanks for that. Now I will wait for a useful comment from someone who can be bothered. :LOL::LOL::LOL: P.S. There is a balance pipe between plenum sides anyway. You cant get uneven boost for each side.
all this and yet you still run a front mount? just doesn't make sense to me. i don't mind the look of a front mount and all, but to loose that much performance on it...... graham, yes there is the balance pipe, which does help (but isn't all that big is it now? ). All in all, there probably isn't a huge amount between sidemount and front mount. I doubt very much the difference between a well setup front mount and well setup sidemount would be 80hp. I like the sidemount. it keeps nissans tuned intake lengths correct, and as said it retains the balance mechanism of cross feeding. on an inline 6 you don't have different banks, so it can't really be compared. One bank, feeds one bank. Then there is no balance issue (besides individual cyclinder issues). I couldn't really quantifiy how important this is. Maybe check flow through balance tube. If it is reasonably large with stock configuration, then it will be even larger with front mount.
yep as I identified the problems and fixed them. most people dont and wouldnt have a clue as their car never gets extensively dyno'd or pressure sensors logged. If my car had been running a nissan ECU then I would of had one dyno run to check A/F readings that would of looked great but in reality on the road there would of been a huge hole in my torque curve as the problem just got worse and worse the hotter the car got.
Re: Sorry I honestly cant be bothered recapping it Are you serious? Is that because of your setup or ? Seems like an awfully largepower drop just from an intercooler! Cheers Adam
so it wasn't the frontmount that was costing you ~90hp, it was the fact that it wasn't setup correctly. so why say this: clearly that implies that the frontmount was to blame. so for all those with frontmounts who "wouldnt have a clue", can you please elaborate what the problems were. Also, why can't this be rectified with a nissan ECU?
No it was the direct cause of the front mount Again this was explained in previous threads so feel free to search on the issue or I'l explain it later tonight or tomorrow again.
Well you know what they say... a Simple life is a happy one, whereas we have to indure some minor frustrations (service more often etc.) but have a MUCH higher standard of life...
Why would people want to have a FMIC which feeds back to the same side? Why extend and have more piping and not just go good sidemounts along with a good body kit that exposes them well? The air hitting them on the side with a good body kit would pretty much be the same amount as being hit from the front regardless of the speed, due to the fact that they don't actually sit on an angle and that a well designed body kit would actually feed them air.. Just go a nice large and well designed SMIC unless you prefer the FMIC for looks.
think i remember now. issue with uneven airflow top/bottom? yep, this would result in huge power inbalance. as pointed out by IB, a vertical front mount would solve this prob i suppose. with all the money you've spent, i'm suprised you haven't gone for one of these. as you found, fitting bigger balance pipe pre-throttle solved the issue. perhaps a step all with horizontal bank frontmounts should consider.
You got it all now Dub Flash looks and thumpin stereo and trick interior and the snazzy girl friend to go with it and now your twin pass rad. Thanks again for prompting me to develop this. Re FMIC I was over at Plazmaman's last night seeing my new snazzy thicker expensive core low pressure drop and efficient FMIC. Gone with same design for now but may go vertical core in future. He is highly regarded in Sydney and around Australia as being the best in this field and funny thing is he says FMIC for zeds better than side mounts. Bottom line is FMIC is more expensive and require better cooling to radiator but results are better depending on design and type of FMIC and Corner mounts. For BIG hp one needs FMIC for various reasons and a big one being you can get much thicker with FMIC as corner mounts are limited in space. Won't mention much more direct air flow than side mounts and much larger volume even same thickness.
There is a autosalon ute here in the mts that has a cooler but no turbo! What the F! you say yeah I pissed myself, its not connected just pipes going no where. What a waste!:LOL::LOL::LOL:
not arguing, but i'd like to see some solid data. such as pressure drops, efficiencies. preferably both of these at various airflows. for what reasons does Plazmadude say FMIC are better for Zs thans side mounts. Does he have quantative details? saying something is better than another thing means nothing without evidence. is thicker better? in general, second half of IC does 1/4 the cooling. pressure drop however will increase with thickness. designing the best IC will always be a balancing act, where you have to balance efficiency and pressure drop. as for ducting, only an area of one forth the IC core area is required. Only minor gains are had with larger areas. Indeed, with regards to airflow considerations, the side mount ducting configuration is probably better than frontmount (kinda hard to explain why without diagrams). I've ripped all these facts from maximum boost (corky bell). john p, i'd be interested in hearing your thoughts about losing balancing effect of cross bank feeding.
If anyone was prepared to ask further If you look at sucessful FMIC pics you will see there is also a balance pipe between the incoming throttle body pipes. Which is exactly what I intend to do. Zisluv, If you care to reread my comments (given this is not my thread) I basically advised what I was going to do and didnt seek advice, but was willing to accept comments. It was you that started on the knocking of FMIC's. I don't need to search. I have done all the searching I needed to do and made my descsion. If you dont like em, bascially thats fine with me. I think its a bit rich for you to jump to the conclusion that anything I upgrade my car with, will not be properly researched, implemented and thus will be crap. Over generalized comments like you made are just plain misleading. It was only after J4play questioned you, that you eleaborated enough for everyone to see the basis of your comments If it can be done right. I will do it right. Just like every other thing I do. I beleive it is a good solution that I will use. It WILL work for ME ! Not everyone is a fuck knuckle when it comes to cars Matey. I learned early on, never presuppose what anyone knows. Very often assumptions like that, will leave you in the shit and looking like a dummy.
