Thats a negative. It will never spool like a 30.

ok fair enough, shoulda said it spools close to a vf30, i stand by my opinion that it wont be far off...
like i said my vf34 untuned probabaly spools at the same rpm that my tuned super 16g will spool, so thats cool with me .

The UTEC smooths out boost values so pay attention to the load site. I'm making target boost before 3500 RPM. I've hit 21 PSI in that same range as well. Tuning will not get you that much more spool so don't get your hopes up. Stock EJ205, stock exhaust manifold (not ported). Its all in the mechanics so free up the flow.
Can somebody help and let me know how to read this chart? appreciated, Drake

^^^ The only columns you really care about are the first two ... RPM and Boost ... At 3330rpms he's making 14.5lbs of boost ... Hope that helps ...

Like this :









All that + perrin turbo inlet hose + STI IC and 3" catless turboback. I really don't think I can free up much more. Plus the exhaust is all heat wrapped and the turbo is ceramic coated.

On a side note: The engine overboosted SEVERELY and blew a head gasket as a result of this porting and polishing. I solved it by P&Ping the wastegate.

Side note 2: if you play that video frame-by-frame, 40MPH to 60MPH goes by in 1.18 seconds. The new Dodge viper takes 1.80seconds to do the same acceleration

Where do you guys get the numbers for the super 16g? I thought it was the same as a big 16g from forced performance.

standard 16g=510
big 16g=550
evoIII 16g=575

Damn this thread is really selling me on the VF22. How do you think this will autocross. I would think worst case is that you slow the engine to 3k RPM's in a harsh corner maybe a split second of lag then booyah! Looks pretty sick.

my VF22 was laggier than my PNP small 16g.. BUT i also put in tgv deletes. the 16g is alot of fun on the lower band. I get ~10lbs by 3krpm and the rest follows quickly.

I will let you know this weekend I expect it to do very well on most courses, but I think a stock turboed car would do better on a very small course with lots of tight bends. The official COBB autocross car used a VF22 for a while, so its got to be pretty good
And on those tight courses... Bah, autocross represents maybe 0.0001% of the driving I do; big deal.

I autocrossed all of last season on a vf22. hella fun, but can be annoying coming out of tight corners. left foot braking would definitely help but i never got that good with that... i have an RA box as well. can't wait to play with the small 16g. funny thing even though the 16g supposably flows more than the 22 the 22 felt more powerful, maybe cause when it hits it hits hard.. but still perceptually it was stronger.

This on 5th gear, level road (slight decline actually).
I'm totally always autocrossing in 5th gear

Your autocross test is this:

Put car in 2nd gear.
Slow to 15-20mph to simulate a reasonably speed for a semi-sharp turn.
Stomp gas pedal and watch gauge.

Here you go

You can hear when I get on it; its just under 25MPH I think. It goes pretty well; some times, if the road is dusty or wet, it will spin all 4 at 40MPH

Try cruising along in vacuum at 40 and then flooring it for a proper comparison to the viper 40-60mph test...
