What 16g maxes out there? Link please preferably on a Tc.

 

I had the drift spec back when I first went turbo and it was 2.25 unless they redid it.

 

Just dump after the spipe and watch the numbers go way up.

 

doesn't megan advertise it as 2.5 inch... but outside diameter? and the inside diameter is more close to 2.25?

 

yeah that version is not equal length.

 

what exactly is "maxed out"??

junk the exhaust

its just a dyno you dont have to live by the numbers. real numbers are at the track

 

i meant a ported 16g with 20g wheel guy with a subie down here is making 360awhp and he thinks it has a little left in it

 

15k + 378whp = FAIL

i make 330whp @13psi and i have less than 3k in my setup

 

Were u end up gettin tuned?


OP:

Exh is your first issue. Second, what gas is avialable were you are?

Pump Gas can only go so far. Right around 18+ PSI is were u see massive timming needed to be taken out.

First Post Dyno Sheet.

Sorry to hear your still having issues. Does it feel good while driving? At that hp, You should have NO 3rd gear on the street.

 

Yeah Big Evo III 16G is rated to 380.

 

I am curious, maybe he is lacking timing in the setup? What standalone are you running? VVT-i tuned? Ditch the stock cams! Run an open downpipe to rule out exhaust restriction as a possibility.

 

megan's inner diameter is 2.25" the outter is 2.5". tsudo is a 2.5" exhaust

 

how much timing? it shouldnt be the manifold, the exhaust you may free up a bit.. megan has 2.25" section on one or more of the bends.. how is the turbo spool and boost build?

If afrs and timing good, consider doing the VVTi map. thats what im doing next time i get on the dyno

 

Ok guys, I will respond and post dyno graph when I get home from work later. I can't get on the site from my job and there's no way I'm trying to use my crackberry to get on more then I have too. In the mean time ill take a ride @ lunch and see where the boost is @, ect.

 

What I don't understand is the inner diameter is 2.25 and the outside 2.5? What the piping is .25"? Anyways it has to be timing and the exhaust restriction. Do what Bret said to do a cut out or jump to 3"

 

yep. they advertise it as a 2.5" but in all reality its not. from outter to outter it is a 2.5" but when you measure the inner its 2.25", which is false advertisement from megan.

tsudo is in fact 2.5" inner diameter.

 

^^ megan advertise its a 2.5, but ive heard it confirmed before it has sections with 2.25".. the pipe thickness cant be 0.25" though lol, is just sections of it that are 2.25

so yeah do as what mentioned, high boost on small exhaust is not good.. run using just the dp and see what happens

 

This post is a FAIL

 

i used the base map crush sent me a while back its tuned up to 14psi, we just made some minor adjustments and its still running rich w/ conservative timing

@trd how is my post fail?? 15k and 387whp is horrible

 

the road between low 300 and high 300 on these cars is an expensive one.

I would hate to see you cross that bridge with a tight budget in mind.
