General turbo engine bay tidy up!!

The other place I remember Aaron tried was getting the air from the vents by the windscreen wipers...

Can't remember why he moved it though unless it just didn't work :D
 
I am sure I have already said on this thread.

The best place for the air intake/filter is up high inside the front wheel arch behind plastic wheel arch line, this way it's col, is not going to ingest water.

Once you get an intercooler working backwards from turbo it should be straight run to intercooler, straight run to end of engine bay/wheel arch and then bend up inside wheel arch, you want as few bends as possible for the inlet track as this reduces spool up time of turbo.

And before anyone says it make a no differance, it does. Both of the cars I have have well known modifications to produce straight intakes, on integrale it requires a small cut to front panel and then weld a very small strengthening plate in move intercooler forward to produce straight run to turbo; on Celica its a a matter of buying smaller battery and swapping positions of intake and battery over to produce straight intake. On both very different applications it reduces spool up times by a couple of hundred rpm.

Yes I did have mine taking air from inside the scuttle panel, but when I fitted a different strut brace bar it took different route and had to change it.
 
thanks for that ;)
and yes you have said that before about the intake positioning(y) as i mensioned in one of the previuos threads above , im simply going to experiment with the space i have available and the new filter and see how things go, that way im going my own way :)

thanks for the advise
 
You're right to be individual, life would be dull if we all did things the same way!

In the end though if it does the trick then it doesn't really matter, but there have been a lot of people that have tried various ways so sometimes learning from other peoples experiences can help save some cash, remember these things aren't cheap cars to run and develop and most people can't affort trial and error. Also be carefull with the CDA's a lot of the Punto guys say they need cleaning more often than normal filters especially in turbo applications where you're sucking in more air than you actually use ;)

There are a certain things that should be a given on turbos that you must do. Fuel pump, fpr, brakes, oil cooler and probably clutch upgrade anything else is up to the individual. but if you get this far and hi boost the chances are you have enough power and anything else will just be tweaking

thanks martyn (y)
well ive got the pump,regulator,intercooler,uprated brakes,,,,,just the clutch to cand im getting the feeling that its telling me it wants changing,there can sometimes! be a veryslight slipping of the clutch under hard acceleration so im going to swap it asap to a brava 1.4 16v clutch as mensioned before ;) once my wallet has recovered a bit from only a few weeks as a turbo owner haha,,,,,,as warned

cheers :)
 
This is how I see it (and then I must get to bed!):

Theory. What you need to know is that high pressure air seeks out low pressure and that the highest pressure area on a car is the very front.

Just as air will try to skip round the sides of a car (and underneath and over the top), so it will try and skip round the sides of radiators, intercoolers and oil filters. You can force it to go where you want by building a baffle from the bumper to the sides of the rad (etc). The baffle needs some give in it or a small collision will take out the rad.

You can decrease the air pressure behind the rad by ducting air out: the vents on the Integrale, the Ford rally cars and the Elise/Elige are anything but cosmetic. Doing them properly, however, so they don't look like bits of plastic tat glued on is difficult: having them done professionally is expensive. In effect, these provide the air with a low pressure area it'll follow, and increase the air throughput. As turbocharging a car is pretty much about temperature control, it all helps.

A case in point, the oil cooler. Most (all?) turbo Cinqs have the oil cooler mounted on the extreme nearside of the car. Immediately behind that is the wheelarch liner. Vent that, just as on the offside of the Sei and you have a wonderful air extractor (the tyre spinning creates a super low pressure area). Box that all in with something like carbon or thin guage alloy sheet (do it right and it can be held on with velcro) so the air can't get confused and wander off somewhere else, then build a deformable structure out to the bumper. One less hot air source to worry about. ;)

thankyou mate (y)
does any one now what size fuel lines are used for the cinq?? i think its around 8mm,,,,as i am going to order some samco fuel hose for it for when if it the new regulator :)
 
right here is another update on the underbonnet activitys of the turbo :)
so far ive tried and failed to fit the new intercooler which is a pain! and is going to take some more work in order for it to take a place on the car! but on the plus side i have now mounted the pressure regulator (with gauge) ready to be piped up and also mounted an oil catch tank (also ready to be piped up) once the hose kit has arrived, the anodised bolts are now in there somewhere,,,,,as for the cool air ducting for the airfilter im still deciding on what to do so till the intercooler has been fitted it will remain in the hot engine bay :eek:
and its worth me saying my problem of the dreadful off-boost hesatation ive been having has been cured by a few good runs with 2 bottles of FORTE gas treatment in there,,,,it now has has a great throttle responce and this car flys!!! :D

RS2000 pump going in at the weekend hopefully!

Looking neat, but why the el cheapo boost controller mounted there (and Aaron will tell you that they're dangerous and to fit an electronic one, and he's right!) ;)

thankyou, yes good of you to notice, dont worry the boost controller is doing nothing at the moment as it is kept shut and an electronic controller will deffinatly be going on if there is to be any boost increase ;)
(it looks good under the bonnet haha) ive been looking at a few boost controllers on ebay but there so many to choose from and big price differneces to :)
any recomendations?
