Im wondering though, (and this has probably been covered before) but wouldn't the bumper restrict the airflow to the top 2/3rds of the intercooler and therefore be a waste of time? Would you get the same cooling effect from using an intercooler only half that height or does it still get enough airflow in behind there anyway? Luke. Sorry but to tell ya the truth i cant answer that one, I'll just ahve to wait and find out! Altho other people have done the same as me and dont have any problems as far as know...

Looking good stefan!
You might be able to keep up to my ED with some boost

why did you decide on a 2 piece flange? wouldnt a single be stronger? also is it 4 mm black steel aswell? also your hole size in the flange, how much smaller did you go? how is the flange for the turbo going to mounted onto the tubes? are you going to squish the 2 ends a bit? or will they fit fine with complete ends? you dont have any progress shots of you flange either do you? looks good, and ill keep watching Cheers Two piece allows for expansion without deforming flange.. There is enough air to cool engine and supply enough to cool air conditioner condenser as well.. So there's enough air for intercooler etc..Infact they are designed to stop air bouncing off ... On the manifold you find it better to angle cyl 2 and 5 ports towards centre or with 1/2 45* bend as it enters main manifold...

Just cylynders 2 and 5? it would even the flow and make it smoother with cylynders 3 and 4 on about a 60* bend aswell?
with the flow, will it make that much of a difference though? these manifold are built for internal waste gates aswell right? |

Correct but the centre two are almost inline with turbo flange which could be at 45* to engine flange plate...It's the 90* bends that should be avoided to prevent reversion rather than flow..Hot gases don't have too much issues flowing, cpmared to n/a engine... Its not uncomon to have 2+ to 1 pressure in exhaust to boost...

- plumb it into the manifold somewhere or - get someone to weld it onto the turbine....

Do what Ebs_4l did and weld it to the turbine housing

I think your cooler should be ok where it is. The cooling affect will radiate up to a certain extent through the core. Also being an engineering student im failry sure i read somewhere this year that the heat transference from the air flowing through the core will be in the vicinity of 50% of the difference in temperature!

I cant do that now because once my setup is up and running I'll be trying out a few differant exaust housings on my car... My turbo supplier is interested in what the results will be on a falcon. So all i have to do is buy the first turbo and then i send it back and he changes it to a differant housing... So I'm starting of with the Masterpower T60 approx620hp The specs to the T-60 are... floating bearing with 360deg thrust. Oil cooled. compressor T-seires T-60, 60.5mm/84mm .7ar comp housing using reflow (antisurge 4" inlet, 2.5" outlet) Turbine mpbt 74trim ( GT P trim). Housing options, .5ar, .7ar, .84ar, .96ar, 1.00ar So I'll start off with the .5ar and if I feel its choking the enging I'll probably swap it for .84ar and if i feel that is still choking it I'll then opt for the 1.00ar

dont even go there.... that divided the whole community, LOL most strongly disgree for the fact that they cant understand the mentality of chopping a hole in your new $1800 turbo.. others strongly agree, because they understand that a wastegate needs to be placed in THE most effective position, and be as an effiecient outlet as possible.. one thing i know is that i will never fit a wastegate outlet to anything but the turbine housing. for anyone reading this that hasnt read my too much boost thread, i can bet you that instantly, after considering those two options (manifold/turbine) you would have joined one of those two opinions... either would or wouldnt chop your turbo????? i understand that alone would make it hard for me to sell one of my exhausts, since i will only run a turbine outlet, but, if im to sell something, and gaurantee it works, then i want to know that it WILL work

Mr Kiss,
Sorry I didn't see your turbo size question thread earlier but it seems you have made a pretty good selection for a Ford 6. I would suggest you don't bother with the housings smaller than 0.84 A/R if you want to exact maximum potential out of rht P-trim 60mm wheel setup. I ran a 60-1mm compressor wheel and p-trim turbine wheel with 0.7 A/R compressor and 1.0 A/R split pulse turbine housing and made 400 rwhp on 19 psi boost on a 250 crossflow. I had massive amounts of backpressure, approximately 7 psi, some of which was caused by the turbine housing and some cuased by the exhaust system after the turbine housing. If you want to get good results from your turbine housing testing make sure you run the biggest dump pipe and exhaust you can fit. 4" dump if you can and then twin 2.5 or 3" to the rear with twin mufflers. It may sound like overkill but exhaust system backpressure will make it hard to evaluate the true restriction caused by the turbine housing. |

Hey with that turbo when did you start getting positive pressure???

With 5.5 psi boost 3300rpm I had 6.5 psi in exhaust manifold
At 19 psi boost and 5500 rpm I had 30 psi in the exhaust manifold. Of that 30 psi there was 19 psi equalizing the boost going in 8 psi in my 3" dump pipe and full system with 1 muffler 3 psi before the turbo I now run a T66 with 1.32 A/R and 3.5" dump finishing under the driver seat with no muffler. It is the only way I could make the power i wanted for drag racing. obviously I had to sacrifice streetability for this. I have a Cortina so ther is not enough room to get a 4" dump down past the crossmember without seriously hacking things. |

What i ment was when your driving around when did the turbo start producing boost??? (with the 1.00ar)
