2002 Bah, Sold My
404whp/414wtq Wagon :(

Default Is 368whp/360tq possible on a vf30?

So quick question.. is this possible?:

This kid is talking so much smack about his car down at the dyno meet the other day. He then said he didn't have the dough to dyno. He states that his car is making 368WHP and 360WTQ. He states his car has:

108 Octane (368WHP, 360WTQ) and 93 Pump (330HP, 320
Vf30 @ 21.5PSI (Here is where I'm callin bs again, saying its "polished")
Utec with what he calls his (done by a ferrari mechanic map, timing at 29)
Fuel Rails
Sti Injectors/Pump
Hks Dowpipe/Uppipe/HKS Carbon TI Cat Back
Invidia Headers
STOCK TMIC
Water injection
Step colder plugs
Larger throttle body.. not ported.. New
Intercooler hoses
Underdrive Pullies (No Air Conditioning)
STI Intake Manifold
Injen Intake
Greddy Oil Catch Can
Exedy flywheel and clutch

I just don't see this much power out of a vf30.. NOR do I see a vf30 being that efficient at that PSI. I have a vf22 setup putting down 322.7whp, 304.8wtq.. on a rough tune.. dyno'd on a dynapack with a vf22 on 93 octane.

Maybe I'm just jealous or whatever.. but I don't see this happening without something up his sleeve.

Any other people think this is BS?

Whif Whif.....I smell a big pile of BS...i've seen some nice numbers come out of the VF30 and race gas, but not like that and not with a stock IC!

Well here's something to consider....

Now I want more and I just sold the 30. Not sure what I'm going to get.. probably gonna go for an used special sauce 20g.

If you're going to pay full price for the VF30, just skip it and just get the 18g. Or an used 1820. And if money is an object, then get the VF22.

There's the magic words...330 whp pump gas w/ VF30 w/water injection is very believable...especially if the dyno reads a little high.

The MAIN BS is 21.5psi out of a vf30 on pump through the stock TMIC. We're talking about losing over 3psi due to flow restrictions, meaning you're putting out almost 25psi into the system from the turbo. I managed to run 20-21 psi on pump, but that was with an APS DR500 and a vf34. Big Turkey ran like 23psi on C16, with the gate held closed by a massive helper spring. That was with a TXS FMIC as well, and that's where he set the "vf30 record" of 345/360.

I certainly do not believe a legitimate 368/360 from that car except with a lying, cheating/stealing dyno operator.

Heh.. I remember that pull... Close one eye, lean back, Anticipate a bang, heart not beating and you certainly are not breathing kinda pull.

I think 368Whp on a VF30 is possible if it was done at TXS or on a Hub type dyno. As power goes up so do the readings. Pay attention to trap speeds. Cars in that range on hub dyno's trap 110 give or take. What gets me is the 108 unleaded fuel.. Thats hard to swallow...

I didn't get that it was unleaded. Man, I would love some 108 unleaded! Where can I sign up?

What dyno was it on? Very dependent on the dyno. My car made 350whp/342ft-lbs on GRD's dynapack dyno and it trapped at 113mph with me driving it (I'm not a drag racer). Dan (triple-x) made 412whp on a EJ205 on the same dyno back in the day and ended up trapping 120+. So I wouldn't say hub dynos all read very high, it was almost identical to what I put out on Cobb's mustang dyno in SLC. I do think TXS' dyno reads abnormally high however.

As for this guy, the 108 octane might have been a mix of C16 and 93/94 or something. If you are running 29 degrees of timing and 21psi I think you could get those peak numbers out of a ported VF30. That's going to be on the ragged edge though.

DWX.. Very true.. Could have been a mix of C16 and 93. When I saw the 108 I thought of the 108 octane unleaded Sunoco stuff I used to run Bottome line.. I have had VF30s in the 340-350 range on Dynojets and The Dynapaks do read higher.. Especialy at those power levels..

Possible? Yes
chane of being BS..... = 80%.

Against him:
stock TMIC = Great grille for burgers and dogs while you make some pulls.
VF30 gate will not allow enough boost to obtain that much power (must be sprung)
It was posted on the internet

I'd say 360whp on a dynapack is far off from truth... vfxx on a 205 would max out about 340whp to maybe 350whp on race fuel moon, stars, quasars and all aligned correctly...

At the same time we have have cars that dyno 320+whp and trap 114+... 110mph heh.. I trapped 108mph on 267whp pump gas on the same dyno, so it's all speculation.

Hey man, that's what dyno numbers are all about! Speculation! Ask him to show us the dyno sheet, so we can see the TCF number. You can make a stock WRX show 370 on a DP or darn near anything else by playing with the correction factors.

Clark, can I get an order of fries with that? We could rig a FryDaddy up on the turbo hot-side, right? Maybe some tater tots?

On my RA 2.0 with STI TMIC on the dyno running 25-30 psi... my TMIC would get so hot it was insane. Rich and the guys where dumping water on the IC core to get it to room temp or close.. I would do one pull which is 9-10 seconds and midway that water would turn to steam...By the end of the pull the IC was DRY and when they dumped water back on it I could hear the sizzle from inside the car.. Crazy hot.

With my DR500 I made 4-5 pulls above 25 psi and a few around 30 and the exit side was actually cold.

I remember the TMICs down here in Florida in 100 degree heat - it was melting the plastic fan housing and at least three of us flash-burned ourselves on them trying to get them cool.
