turbo'n my car!!

[rickles8099]

that is true.....but you could flow 250 cfm at 10psi, and you can flow 350 cfm at 10psi (these are just random numbers). Equal pressure does not always equal flow.

yes. but to do more cfms at the same pressure, you would have to increase the size of the piping/throttle body/intake manifold. and this is the point ive been trying to get across. a bigger turbo doesnt always mean more power.

Ah, fuck it... keep it going I guess.

[.:si:.]

and 10lbs of pressure is still 10lbs of pressure whether its from a big source or a small source.

the bigger source can push more air but when the air reach 10lbs of pressure in the system, the wastegate opens and you only get 10lbs of air. 10lbs of air with a big turbo equals 10lbs of air with small turbo.

agreed but how come my buddy put down 325 on a evo with stock turbo on 22 psi and put down 395 on the same evo with a gt35r on the same setup and 22 psi? answer me that...?

and silverstreak i have been looking into that stuff and i have the high flow cat for the evo 2 exhaust system and i know bout the valvetrain on the cats and im researching on the pistons whats the best brand out there...intercooler im researching that too....probably 2.5 on the downpipe im gonna talk to matt from htp bout making a 3" turbo back though so im not sure...for the turbo the 16g should be good...not too laggy and will be more than capable of what i am wanting considering evos can put down 28 psi with em...intercooler piping and all of that shit i can figure out too...hard piping would it be needed on my car i didnt think soo...help me out guys never turboed a car....need all the help that i can get....i got a guy with a 600+ hp srt4 and a 400 hp evo helpin me so thats a plus...thnk yu

alright. but at a given piping size, a larger turbo will run [insert number here] psi more efficiently, correct? at least as the desired psi number goes up.
that was my point... if you have ...say 2.5inch piping, and you have a specific horsepower goal (which would mean a desired cfm number), for the sake of efficiency, wouldn't it make more sense to run a bigger turbo at a lower psi than a smaller turbo at a higher psi

not always....I would like to know what kind of manifold pressures (exhaust) are built up before the turbo. I would think that a larger, more free flowing turbine would ease the pressure in the runners....making the motor just plain run more effeciently. You wouldn't have as much pressure fighting against the incoming air charge (for whatever amount of overlap you may have).

There is probably a lot that I don't look at....but I can't see how there wouldn't be a very noticable difference at say 15psi, between a gt30r and a tdo4-15g.

is 22psi on the stock turbo past the turbos efficiency range?

[.:si:.]

no thats there sweet spot they can put down 28 efficiently

alright guys still been doing some research on the whole turbo'n my car thing and this is what i have came up with...

i emailed synapse turbo...in new york!! supposably they know their hondas to a t...anybody heard of them..my buddy use to live in new york and said that they did some really good work but this is what they told me...

on a healthy b16 they could put down 300 w/ out internals on a good street tune...

they told me 6000 dollars for all of this installed and everything

gt28rs turbo(good response from what i was told)
spec stage 4 clutch
ram horn manifold
3" downpipe
3" custom exhaust
2.5" charge piping
garret core intercooler 24x6.3x3
tial 50 mm bov
tial 38mm wastegate
all the couplers oil lines and hardware
all of this installed
obd1 ecu chipped for neptune or hondata s300 ecu
then whichever one of the 2 computers that i wanted
neptune licensing fee
precission 550cc injectors
walbro 255lph fuel pump
bgk bkr7e spark plugs
complete dyno tune
street race tune
race gas tune
and daily driver tune..
all on a 8 map switch..

what do you guys think on the price...the set up...and the shop?

[J8k'S CRX]

im going to say it now. BE CAREFUL. ive had a few friends go down with the snail lately and i would hate to see that car be added to the list, so just be careful. and good luck.

sound expensive, that more then ill have in my entire built engine,and 400hp turbo set up.. so that on you
