Im thinking about installing a boost controller for my turbo, only problem is i dont know to much about them and have no experience using one, whats the difference between manual and electronic, im running seven psi right now and i know i can run more which is why a boost controller makes sense to me i can crank irt up to 9 or sometimes even 10 when i want. also whats the most i should push the car im not sure how much power the 4.0 engine could handle and the tranny. Please help

wikipedia is your friend

Boost controller - Wikipedia, the free encyclopedia

electric is suppose to be a little safer and more accurate
i'm using a manual controller. the only thing i dont like are the spikes

the 4.0s after about 9psi you have to worry about valve float
i would look into stronger springs before turning the boost up to 9+psi

electronic you just use a button to turn boost manual you turn by hand...
i run mine inside the car

IMO if your going to get stronger springs you might as well look in to a set of cams
see more power and run 9-10psi with over 400rwhp for sure

Thanks chris im also looking into the 70 mm throttle body, aluminum driveshaft and underdrive pulleys, maybe il just stick with what i have now and do everything next year, you have any type of price range for stronger springs and cams???

[turismo374]

also chris maybe eventually il go with supersixmotorsports what do u think about the ported cylinder heads, cams, head studs, and valve springs

[TurboLX]

are you that black turbo V6 down by DPA?

ssm is the only place with heads/cams for the 4.0

[turismo374]

lol no mine is blue and im in ny wheres ssm do they have a website i saw everything for the 4.0 on supersixmotorsports.com check it out what do u guys think

[turismo374]

lol im sorry you are talking about supersixmotorsports what do u recommend from there i was thinking the stage 2 they have a 4.0 at over 400 rwhp can the transmission handle that much?????

[Youngin]

stage 3 heads and cams.. you can do stage 2 but i thought stage 3 heads were required for cams

[itschristorres8]

what kinda tranny
and whats done to the rear end?
i dont sell parts for the 4.0 sadly
the most i could really do is P&P the heads order parts from supersix for you and assemble the head

i would do the minor bolt ons you wana do first then think about head work

[turismo374]

This is everything thats done to my car...

sts rear mount turbo tuned with diablo handheld at 7 psi
shorty headers
8.8 rear end with 3:31 gears and t-lok
i have a wideband air fuel ratio and boost gauge installed as well.

I want to eventually get a 70 mm throttle body, powerhouse aluminum driveshaft, underdrive pulleys.

and i guess the stage 3 from ssm and after all that a good dyno tune, i should get great power with all those mods i dont know how much boost i couyld safely run with all that, u have any ideas??? also how can i beef up the tranny to handle that much power i have to be pushing 500 hp with all that

[Youngin]

you can always get a racing 4r70w tranny

and are you running the stock 28spline or 31?

[her name is ponie]

STS huh

[turismo374]

31 spline

[Youngin]

are you gonna get forged internals?

[turismo374]

yes i plan on getting everything from ssm

[Youngin]

wow straight baller~

you getting the block or just internals

[turismo374]

stage 3 superheads im going to leave the car the way it is now at 7 psi the car is alot of fun now and im going to do everything else in the spring of 09 70mm throttle body aluminum driveshaft underdrive pulleys and the stage 3 superheads running as much boost as i can!!!! lol my only worry is how to make the trasmission stronger i mean the car is an automatic how can i make the stock transmission stronger???

[Youngin]

im telling you get a built 4r70w..
