This is my Dyno sheets, this one is standard only with a hks cat back 3inch and cold air intake.

TRDmod · Post by **TRDmod** » Mon Dec 11, 2006 10:28 am

This one is with a turbo netics 450 rated turbo. two settings here, high boost is 15.8 and the low boost is 12 psi. custom manifolds, cold air intake, 3inch.

Your boost curve sucks, any form of boost controller in there? KiwiMR2's old car held boost beautifully with fairly similar mods.

the first dynograph has no boost controller its standard
the second one looks a lil better, it has profec type s , the one with three dials

which on ar eyou refering to? the second ones boost curve doesnt look too bad
but the first one sucks i must agree, jsut standard..

The first one. The 2nd one is much improved, good top end there too

not bad for a GT4 with out touching the internal

keep it going

Where is the fuelstar dyno?

TRDmod · Post by **TRDmod** » Mon Dec 11, 2006 11:02 am

not there yet, february next dyno day. the guy that does my car will get his own dyno soon on the shore, which should make it cheaper to dyno my car and yours!!
but feb next TP dyno day.

im jsut a little concerned with the low end, as i changed the turbo, the low end suffered though the top end greatly improved, wondering how i can bring up the low end slightly up to make it a more flatter curve. any suggestions. (cheap ones):)

see, the thing is, it will cost alot to do the whole internal side of things

though, if anyone here can recommend a cheaper alternative to enable me to pump up the boost say.. 18-21 psi... let me know

i mean i know doing the pistons and rings would be cheap.. wel relatively cheap, i mean pistons retail go for 1400 with rings, install, lets say 2200 to do so.... if i do that, would that enable me to pump up the boost hardcore with out doing anything else?
i hear the conrods on gt4s are strong, and the piston is the downfall of them...

any feeback ont hat, cos i really want a lil more power for the cheapest price, sure i can do computer 2200, all the engine internals 4k probably. just exploring ideas... i know i got told that you might aswell do everything if your gonan do pistons... its not much more
but u know.... money is money....a nd i dont have that much of it im willing to spend on this four wheel liability:)

It'll cost you alot more than $800 to have a set of pistons installed

To improve the low end, you can either A. Install antilag B. Bump up the base timing :lol:

or C. Get some custom ground cams to help.
With a big turbo, you're never going to have the same low end power as a stock turbo, there is always going to be some sort of trade off.

Full boost at 4500rpm

Nice power though!

TRDmod · Post by **TRDmod** » Mon Dec 11, 2006 3:22 pm

the turbo is big ish
thts why
but the top end power is definately very fun
but looking for cheap alternatives to get low end higher

Steel flywheel.

Won't imporve the dyno results, but sounds like the only answer to what you want/want to spend.

Could it not hurt to TRY smaller intercooler pipeing? might be as simple as that? take what you got in to a pipe place and say replicate this as xx size as apposed to this being xX

TRDmod · Post by **TRDmod** » Mon Dec 11, 2006 3:45 pm

i see
what would decreasing intercooling piping do?

my theory: correct me if i am worng

because its smaller it takes less time to fill up and create a vaccuum pressure ont he pipes and intercooler
hence making it more responsive earlier on?

2.5 inch is plenty big enuf

Have you done any fueling mods?
My st205 made 206kw atw too, then it went bang :lol:

Lith · Post by **Lith** » Mon Dec 11, 2006 3:59 pm

Substantially improving low end really is only going to be done by going to a smaller turbo. What turbine housing does your turbo have? If its quite big (Ie, over .8x) then going to a .6x would bring things down a few hundred rpm. It'll still be nothing like stock, but should help and be a fair bit cheaper than changing the entire turbo.

Alternatively, sell the turbo and buy a smaller one - decide how much power you want.

decreasing the piping size may help response but it wont help with lag much.

The second graph looks nice power wise. I found torque didnt tune my car properly. Yours looks quite good.
