I have an R manifold ,16t Angled, 3in Dp, 2.5 catback.
Ipd stage 2 17 psi Euro Tune.
Cbv Hd spring.
s60 t5 tcv(60k)

I am making 8 in 1st
15 dropping to 14psi @ Redline in 2nd
17psi droping to 15@ redline in 3rd

Have not had the chance to Run 4/5ht to redline.

I am Thinking about getting an Ebc and Fmic??? Would these help hold full boost better?

What Boost are you guys making and holding???

[Wagoneer855]

Mine drops about 1 psi near redline.

Don't bother fixating your time on holding full boost to redline. Have you seen how HUGE our hotsides are

[magicaljake]

that sounds about right....

what year is your car?.

just wondering

[Fake-R]

Stock TCV?

None the less, I hold boost. Turbonetics MBC, 19T, ipd tune, greddy bov, etc.

Same here (see mod list, below). About as fast as a Prius 0-30 mph with 8 psi in first. Every other gear is fine, though. Around 15/16 psi or so.

Good question, I neglected to mention that I am running a 2004 s60 Turbo Tcv with 60k (it was Free)

I have a hallman pro that I can install until I get an ebc..

Alot of s60 guys replace their tcv around 60k. I just hit 60k and plan on replacing mine with an ipd unit. Im not saying this is why your not holding boost but you might wanna look into that also as its and inexpensive mod/repair.

Boost fade freaked me out. 18T, 3" turboback and MBC. Still it faded.

So I bought a GT35. Problem Solved.

[Big Will]

Boost is limited in 1st and maybe somewhat in 2nd, I haven't paid attention but 3-5 boost roughly 16 PSI to redline. Mods in my sig.

I've been trying to get my car do to this since I bought the damn thing

S60R manifold, 3" unbaffled (but muffled) turbo back exhaust, n/a cams, fmic, flat flange 16t, custom Garrett 11psi wg actuator from ATP turbo and a Greddy Profec B Spec-II boost controller....I have 12psi at 6 grand I'm pretty sure that if I held 18psi to redline I'd be close to 300whp. At 12psi when I dynod I made 242whp...I'm eager to see what happens once we figure out how to hold boost. I think the only thing left in my equation is the wastegate flapper itself not sealing...it's the only possible mechanical reason that I wouldn't be holding boost.

[Boost3237]

With my old '96 850 I had stock everything except 3" turboback, 19T/tune, and MBC. It has ~240-250k miles, good compression and held 19psi all the way to rev limiter. When running 22-23psi it would fade to 20psi.

[L8 APEKS]

These threads are always so weird to me...I've never owned a boosted car that DIDN'T hold full boost to redline! I've also never seen a boost spike first-hand...

[randomdude]

^well, let him know your secrets

Same here, had 2 cars with the same motor in them though otherwise I've always had full boost to redline, I have though seen a couple boost spikes but that was due to other issues (one of which I melted the vac line off the bottom of the turbo effectively disconnecting my MBC) that was fun still I caught it cos I drive with one eye on the boost gauge and one on the tac.

^what does your other one look at?

Please Elaborate. What are your mods.

I am not calling anyone a liar ,but I have a M56h swap with Quaife, There is no way possible to build full boost. Look at nearly any forum, Wrx sti don't even make near their full boost.

In an automatic it is electronically limited , that and traction loss(open diff, With a M56h and quaife still not enough grip(225/45/17 On Zr Performance tires, Bf Goods & Bridgestone.

That and the gear ratios. Ipd says it can't happen.

[Black Betty]

First off I would never claim these mods as mine..but these are the cars mods
NA cams w/ QBM cam dial,Unorthadox racing underdrive pulley, S60R exhaust manifold ported and polished opened up to a t3 outlet 10mm studs, New HAHN Racecraft Super 16G turbo, Custom all Mandrel SS 3" exhaust own pipe has 1 SS flex bellow and a 2 bolt flange into a round borla XR1 muffler into another flex then some pipe into a magnaflow resonator then over the axle and another 2 bolt flange into an oval borla XR1 muffler out to a gibson rectangle polished tip, All custom aluminum intercooler piping 2" hot side 2.25" cold side w/ all blue silicone connectors and t-bolts, 24x10x3" bar and plate front mount intercooler w/ 2.25" inlet and outlet, HKS SS BOV, Ported intake manifold w/ NA 850 throttle body w/ 960 throttle plate, New FPR, Walbro 255lph pump, New fuel filter, S60R 465cc green injectors, Crank case breather kit recently replaced and plumbed into a catch can, BMC carbon fiber canister filter, Custom 2.75" aluminum intake pipe, MSD coil, OE cap/ rotor/ wires, Bosch Copper plugs gapped to .022, Greddy profec B electronic boost controller, Greddy turbo timer, 22psi, Custom tuned ECU for all my mods.


I really don't care if you think im lying or not, but I hold boost til redline and when 22 psi hits in first and second the tires light up and occasionally third as well.


Future plans are built motor.
