Supra Pilot

Again I have to say.... I understand all that what you are saying.......but the point I am making is 99% of people on here that put a ring in was because of 'boost creep/high temp'! THAT IS A FACT...... They use(d) a ring to cure that....... Stability yes, but the MAIn reason was to stop the above! It is all in past threads............. Whats the first thing that is said when people do a de catt, (besides saying boost pressure is unstable).. Typical thread on here.... 1/ Question : what next do I need to do? Answer : 'An EGT gauge' (on this forum) 2/ Ques : Why? Ans : to moniter and make sure you don't run hight tempts (with your new half done mods.) 3/ Ques : Ok thats done, I am getting quite high temps and boost raising to 1.4 etc.. Ans : wooooo, thats dangerous......you now need a ring to stop that 4/ Ques : Good ring fitted, boost now more stable, temps not so high 5/ Ques : Now car is fine, but boost limited and brought back down because of this..... 6/ Ques : Seems I have not gained much here really... MY Answer : because you have done half a mod(as I keep saying). and should of gotten a proper solultion from question 3/. 'Right this is a typical thread on here'..all the time....... Someone asks that first question and thats the immediate answer he gets swamped with! It's the wrong answer, thats the alternative answer...... Look I am not trying to be difficult guys,,, I may have said this all in a confusing type of way.....trying to type this at work here, in between my job... But as I said, there is no way you can say a ring is a benifit to power gain.....it is a cheap cure for a problem created by an incomplete mod...... End of the day, everyone does mods and spends loads of hard earned dosh doing this to achieve more power/speed (thats a FACT)....... Like to hear the big power supras on here say if they have a 'restrictor', sorry a ring...or have any of your big power machines you guys 'Nathan' built have one of these in them....

Sorry guys, I may have gone off abit there....I do applogize. Basically what I am saying in simple terms is everyones wants a de-catt as it is one mod that 'is' required if you want to gain more power... Which it does....but in some cases it does this sooo well that it results in too high a boost pressure, with a resultant high eng/exhaust temp. Which high boost pressure is good if used correctly and controlled, but you don't want high temps.... You want more boost thats why you re move the catts to achieve this....but putting in the ring, you bring/limit the boost back........ there are many ways to keep the free boost safe and useable after the de catt to make the mod purposefull...... So thats basically the point I am getting at here....... Chris the ring is good and safe yes.....but whats the point of doing a FULL de catt if you are gonna put another 'restrictor' in! Appoligizes to all

I suppose someone is going to want to try and explain another FAMOUS word ---- 'back-pressure' now........lol

Thank you Darren That is exactly my point.....95% of people on here are generally NOt technicialy minded(we do have many 'text book' mechanics/engineers)......and most here saw another did this and did that and got results etc, and want to do it too. ANyway the fact is the less restriction you have on any system(within reason), and especially a performance car the better. The basics of any engine is to get your juice in and out as quick and efficiently as possible.... it's called 'breathing' You take the catt's out for the engine to breathe better, she breathes better, the performance will get better.....simple and true(within reason and many other parameters). And most people that have done this, have noticed a difference! Including myself......... So basically it is benifical.... But then you are getting a down side with in the area of high exhaust temps etc.. this is very easily controlled or rectified. I won't say how, as there are many ways to do this! But the simple way I see it's been done on here is by the 'magic' restrictor ring...... Which as is proven is going back to square one again!!!!!! I wonder why those idiots in F1 or even in top fuel drag(fastest machines on the planet) don't use a Catt.... or even a silencer/baffle etc....just a raw manifold......

Hmmmmmmmm, thats unusual.............. . . . . . . . . . . . . . . . . . . Sorry m8, you looked for that......... Anyway have you check your 'wheel nuts!'

Yes Steve I am using '5's' on the plugs for now..... Matt you're not wrong there m8...(check your Pm's) 2 of the plugs (#2+3) had a couple hair line cracks on the ceramic insulation.... But the plugs themselves/on the whole were still in very good order... Dom

Nick, I personally don't like spoilers like that on ANY car, think they are suited for pure track cars. They are 'real' spoilers(purposefull)...not for cosmetics I will reserve judgement on yours as I think it needs to be seen live..... Those photos you took are not at all flattering(?), especially that rear shot.....I think that rear angle shot exaggerate the height etc of it..... Thank god for nice wheels though.....

Hi Syed, Thanks again for the info you passed on m8...... I used the 10W-40 Castrol Magnatex...... I have done a full service on here now, all filters, plugs + oil, plus a little tune up... It can all be done in under 2 hours easy.....(everything) I only need to get some new plug leads now.....so I will be ordering a set sometime soon... Of course this involves removing the throttle body assy again to change the leads! I have more photos if and when someone else tackles this....... Have a look at the photo below and see if you can spot the difference:eek:

I dissagree, Most here have done a 'de-catt' for more power(the big BPU) and then realize that the boost is running away/or gone too high. Going too high is not bad but it's the associated high temps to accompany this is not good... So to combat this, a quick fix is the magic restrictor ring........ This IMO is not really solving the problem as you are going back to square one in lowering the boost! When the reason in the first place(de catt) was to get MORE BOOST!!!!!! Seems like 'Pissing into the wind there.....' The real problem is not being address, 'High Temps'..... Many many ways to solve this problem.....but someone comes up with a 'quick fix' or cheap fix and says put this ring in,,,,, ok we will sir... And see's results that the boost is stable and all is well.......but what was achieved in the first place...nothing really was it........ When an exhaust system was designed, do you not think they thought about all this, 'restriction and flow etc', whats the best for the engine performance and turbo function....... Anyway I won't get into more about tis as I can go on with it and prove it more and more...... At the end of the day, you cannot convince me that a restrictor ring is required...... 'It is a cheap fix for a modification that is in complete!'

Once everything there is disconnected, just raise/move the throttle body to the side and you have loads of room to remove the PLug wires and then the plugs........ When done, the reverse is the order of the day!

Hi gents, just an update on this little gem here... I have just completed the plug change task..... Well most here were running scared of doing it because of what's involved as you saw from the Toyota maintenance manual and the corresponding real live engine photos........ I was actually told to make sure I put aside a 'WHOLE DAY' when going to tackle this job...... Anyway it is an absoult piss really, done it on just basic common sense... I have also attached photos etc for better understanding as the Toyota Manual is very misleading and seems to tell you to do lots more than is actually required for the task. Took me less than an hour to complete, having never done it before. Half hour next time MAX! Good Luck.......

A very sensible thread here....... I never understood the logic of fitting a restrictor ring in a pipe! I understood why people did it, but as I said it's not 'logical'! And I won't go into details as many here will get lost.........

The search button is your friend, do not be afraid........... . . . . . . . . . . . anyway m8, click here and your prayers will be answered.....

Sorry John, I have sent you a Pm regarding this m8... Come to think of it I am having a wee problem with my PMing. Tell me if you get it or not please...... Dom (I have now sent another to you)

Again, I still say 'springs'.....'coil-bind' edited as I had to add: Boot rubbers are quite obvious.....and as in your first post......'going round roundabouts etc.'........dodgy boot rubbers will make noise in a straight line.......

Matt I actually saw a car(a supra actually) with a similar contraption and with quite a number of wires from it----including a co axial cable...... And it was from a hands free phone set up with an external antenna. So just assuming it's possibly the same thingy.....

It's for a mobile phone.....external antenna booster.....(looks like)

Well it seems you don't seem interested in what it's really for... Just hope you wern't driving the car without it.....

http://www.streetmap.co.uk/newsearch.srf?x=612750&y=242250&z=1&ar=Y&isp=200&ism=500&searchp (click the zoom out button twice on that map-link and you will see 'woodbridge' in the top left corner...) Those coming from midlands/north will be coming down the A14, those from south and london, will be coming up the A12. The A14 and A12 meet at the roundabout where this tesco is situated.

I will post the link up later, but out of interest I will be from M11 jct 8(Stansted Airport jct) onto the A120, which meets the A12, which goes directly to the meeting point.

What springs/shocks have you got on the car?

You mean this!

No helmets AFAIK. Last one was quite casual..... It's just masive open space really, got to a twat to flip really:moo: I paid on the day, but I reckon this time may be better in advance as it may have a bigger turnout. And this time you know(will I know) what to expect, so it may be well worth it to pay asap. Dom
