Ricky@Race-Tech Posted January 15, 2013 Share Posted January 15, 2013 I haven't got a standard one, and to be honest don't think we will do any more. We are currently working on a super cheap intake. They haven't got velocity stacks inside. Just a taper on the base of the plenum. But the cost is more inline with others. If somebody wants one we can back to back test it against standard on the dyno. Price will be £250 fitted and tested for the first person. (£200 normally)Ricky, any chance you can post pictures of your standard and race spec inlet to show how they differ? Quote Link to post Share on other sites
Lew91 Posted January 15, 2013 Share Posted January 15, 2013 What about the actual plenum size and shape tho? Does that come into account or is it just the stacks them selves? Quote Link to post Share on other sites
Ricky@Race-Tech Posted January 15, 2013 Share Posted January 15, 2013 What about the actual plenum size and shape tho? Does that come into account or is it just the stacks them selves?Yes, you aim for a specific size, then the shape is used, along with any method to improve flow. I.e. stacks, base plate. To balance the flow across the cylinders. The shape is also important for a number of other reasons. The intake I have drawn up today actually will perform very will, and the construction method will keep down the cost. Quote Link to post Share on other sites
Lew91 Posted January 15, 2013 Share Posted January 15, 2013 Wow a lot more goings on then meets the eye then. I'm guessing it helps if all the internals are deburred and polished also? Quote Link to post Share on other sites

Ricky@Race-Tech Posted January 15, 2013 Share Posted January 15, 2013 Much less than you'd think to be honest. Surface finish doesn't make a deal of difference because of a "boundry layer" there is hardly any gas speed at the surface. Sometimes a sharp edge can help you, as it causes the gases to "tumble" and move in a certain direction easier.

Lew91 Posted January 15, 2013 Share Posted January 15, 2013 (edited) I've just read this and it answered a lot of questions, http://www.intengineering.com/intblog/archives/693I think if I was going to build one myself I would personally use raised stacks while making the runners as long as poss with them becoming thinner half way down. Think I would have a smoothed surface finish tho, not quite mirror but at least have a reading of 0.8 RA. Edited January 15, 2013 by Lew91 Quote Link to post Share on other sites
Ricky@Race-Tech Posted January 17, 2013 Share Posted January 17, 2013 Hello, Our very latest intakes are pretty much exactly as you have said. We always went for the raised stacks and realistically the longest runner that is viable within the construction. On the very latest intakes we tapered the runners as well and were happy with the results.

Just out of interest, and for future reference if he does a cheaper version with flushed stacks but still tappered and with the correct plenum size and shape would that be enough to support a 250-300 bhp build with out doing any damage and improving results?

pick1 Posted January 18, 2013 Share Posted January 18, 2013 I don't fully understand the inlet side of things but would there be any point uprated your inlet if I were runnin 250bhp cuz the standard one can support up to 300bhp as far as I'm aware Quote Link to post Share on other sites
ro55ifumi Posted January 18, 2013 Share Posted January 18, 2013 Standard inlet on mine @ 278 John Quote Link to post Share on other sites
Azz Posted January 18, 2013 Share Posted January 18, 2013 Socks ran 370+ on the standard one ! Quote Link to post Share on other sites
mattyD Posted January 18, 2013 Share Posted January 18, 2013 Socks ran 370+ on the standard one !Hmmmmmm. Standard one becomes a restriction after 350 so not really sure how that worked Quote Link to post Share on other sites
Josh@TunerLifestyle Posted January 18, 2013 Share Posted January 18, 2013 even if it makes little difference they look sexy and make a nice addition to the bay your all tarts Quote Link to post Share on other sites
Azz Posted January 18, 2013 Share Posted January 18, 2013 Hmmmmmm. Standard one becomes a restriction after 350 so not really sure how that workedI'm guessing he will he having a new one now from rece tech while his car is there because of that very reason pall Quote Link to post Share on other sites
Driver Posted January 18, 2013 Share Posted January 18, 2013 Just remember guys, although the stock inlet may be able to cope at 300-350hp but with a better designed inlet you could get a wider torque band or make power earlier and make better power at less boost. It's not always about replacing it because you have to but optimising your setup. Quote Link to post Share on other sites
mattyD Posted January 18, 2013 Share Posted January 18, 2013 (edited) I'm guessing he will he having a new one now from rece tech while his car is there because of that very reason pallYeh, no doubt he will be having a new one dude doesn't make sense that it made '376' one the standard on when it was Ricky himself that said it becomes a major ristriction at 350.......

rob_bower Posted January 18, 2013 Share Posted January 18, 2013 Just because it becomes restrictive at 350ish doesn't mean you can't run more just means with the correct inlet the same setup ie more efficient and effecrive inlet you will see more efficient outcome ie more torque, driveabity and possibly power.

mattyD Posted January 18, 2013 Share Posted January 18, 2013 haha, my bad! I was under the impression it hindered the setup after it had a certain amount of pressure flowing through but I will shhhhhhh now Quote Link to post Share on other sites

What are you suggesting? What doesn't make sense? There are gains to be had swapping intakes before 350hp, before 250 infact. But it doesn't mean you cannot go above that figure.

Simon Posted January 18, 2013 Share Posted January 18, 2013 The cruise car runs a stock toyota inlet: When it was running the 3037S three years ago on a 4E it reportdly made 480ps but on what fuel it doesn't say. http://minkara.carview.co.jp/en/userid/784493/car/747904/profile.aspx Quote Link to post Share on other sites
Ricky@Race-Tech Posted January 18, 2013 Share Posted January 18, 2013 It is probably heavily ported, on nitrous or race fuel or both Quote Link to post Share on other sites
Simon Posted January 18, 2013 Share Posted January 18, 2013 It is probably heavily ported, on nitrous or race fuel or both Never seen them use nitrous doesn't seem to be something thats used in Japan very often, but i would expect it was running some kind of race fuel as it was when they were racing with it quite a lot. Has been swapped to a 5E again since then with a HKS turbo and is about 320-340 ps. Quote Link to post Share on other sites
Lew91 Posted January 18, 2013 Share Posted January 18, 2013 So really then if some one was to do a budget inlet for cars capable of 350bhp or less it wouldn't really matter how they were constructed any way? Quote Link to post Share on other sites
