tuning for turbo

[cougarman30284]

ok right now getting ready to put a t3 or t4 custom turbo setup on my 99 cougar 2.5 and was wondering when i get it tuned will that take car of all my cel lights

like ones bank 1 and bank 2 running to lean thats becsaue of the cold air intake im pretty sure so what i was wondering when i get my car tuned after install the turbo kit will that take car of all the lean and probs and make the turbo run right and no more cel lights reading lean i hate running lean

[brapple]

I am sure they can richen the car up if it is running lean with a tune but I don't think that is the best way to go about it ...


I don't see how an intake can make you run lean unless it is leaking air after the maf ... if you are running lean I would fix the problem first before tuning for a turbo


also what else have you done to the car? the duratec runs rich from the factory as it is, I don't see how it could be running lean unless there is a air leak ...

sounds like theres problems already without the turbo.
Eliminate the problem you have now before you proceed.
What else are you putting in for a turbo?? injectors, intercooler, and what type of tuning are you going to do?? which EFI system are you going to use??

[cougarman30284]

well im going to put 24lb injetcors from a mustang gt in doing the svt upgrade and intercooler dont know right now but i want at least 350 to 400 hp and getting a bigger fuel pump and fuel regleter and do not know what kind of tunning to get thats why i was asking

[TrackCat]

are you asking what stand alone system are you going to use??

400hp x .6= 240
240/6 = 40
40 add 20% = 48
You need 48lbs injectors and at that rate 55psi in the fuel line
I would also do a compression test on your car and varies tests to see what the condition of your engine is.
and have you lowered the compression of your engine yet? to reach 400hp you will need more boost and lower compression.

Are your calculations at the wheels?

Either way, 42# injectors have been show to safely provide 400wHP
36# are good to at least 330wHP, probably more like 350wHP.

That is because the rating is at 39-45psi depending on the manufacturer.

We generally convert the injector to a 'relative' injector size by going from 45 to 55psi fuel ration. This makes a 19# injector about like a 22# injector, and so on.

all calculations are BHP.
40 is whats needed to provide 400bhp. I always go 20% over so I will not overwork the injector.
350bhp would be 35lbs but add 20% so 42lbs is great.

So you do realize that I set down 330 wHP on 36# injectors with plenty of fuel left don't you? That is 400 BHP.

So I think your WAY overestimating the injector needs.

The 42s have made 400wHP and that is about what about 500BHP?

Sorry but clarify where you get your position please. Are you saying that injector size affects BHP??

I always use dynos that read off the hub or Engine Dynos for accuracy. I really don't spend time on dynos that measure power at the wheels.
As for 400Whp to 500BHP I would seriously fix the transmission and some lighter rims and maybe a stiffer suspension to cope with the Driveline loses. Oh and maybe new mounts and lighten the flywheel
